The necromancer just wants to plant trees

…

“‘Chaos Puzzle Lock’, as the name suggests, has the effect of making people’s behavior and thinking chaotic.

The three major mysteries of the gods are actually closely related——

The intellectual mystery lock allows the creatures on this continent to forget the gods and history.

If history is lost, people will be confused;

The civilization mystery lock blocks the possibility of civilization development, which is equivalent to locking the future.

Unable to see the future clearly, people are even more hesitant;

The Chaos Mystery Lock has the effect of completely trapping people in place and spinning around wildly.

Because thinking and behavior become chaotic, you may make up your mind to do one thing one second, and start doing the opposite thing the next second.

in this case.

Civilization on the continent of Irondor was almost completely undeveloped.

This is exactly what the gods long to see.

And when the confusion in people's hearts accumulates to a certain extent, they may again beg the gods to come and give them guidance.

This is also a loophole that the gods found when they painstakingly studied the rules set by the natural disaster mage after they ascended to Tianlun Palace——

If on a certain day.

The creatures on this continent welcome their return wholeheartedly.

Then it is really possible for them to come back. "

I see.

The third mystery lock is actually a chaos mystery lock!

Matthew frowned in reflection.

Check in your memory whether your behavior is also affected by the Chaos Enigma Lock.

"Is the Alliance of Seven Saints indifferent to this?"

he asks.

Margaret shook her head and said:

"Of course not. In fact, the legendary mages headed by the Seven Saints have made a lot of efforts to fight against the mystery locks of the gods.

But you also need to know that setting up mystery locks by the gods is a desperate effort.

They were careful and well planned.

If we want to counteract the influence of their mystery locks, the quickest way is to find the location of the mystery locks and then isolate them.

And in the process of searching for the three mysterious locks.

The alliance has actually suffered considerable damage.

Because the three major mystery locks are all in the outer plane, there are many evil forces watching them.

After the natural disaster mage left.

The Alliance lost the ability to single-handedly suppress the entire universe.

During that time, the atmosphere within the league was said to be depressing.

The three Tongtian mages have been busy working on the three mystery locks almost all the time.

The first thing to be found was the Intellectual Puzzle Lock.

The time is one week after the gods lowered the mystery lock.

It was discovered to be located in a secondary plane sandwiched between the continent of Irondor and the Abyss.

The gods have invested a large number of troops there to guard it, and there are suspected plane traps specifically targeting legendary mages and divine mages.

Although we cannot completely destroy it.

But with appropriate counterspells, the impact of Intellect Lock is greatly weakened.

As long as your intelligence is above fifteen points, you can avoid forgetting it by reading history books and hand-copiing deeds of gods.

You know, when the intellectual puzzle lock is not weakened, almost everyone has forgotten what happened before.

That was the most terrifying and depressing time.

However, in order to isolate the influence of the intellectual puzzle lock.

Lord Linde, one of the three great Tongtian mages, has to guard outside the secondary plane at all times.

For more than a hundred years.

His body was ravaged day and night by the starlight and rays of the universe.

The situation is said to be far worse than before. "

Speaking of which.

Margaret couldn't help but sigh softly.

"So the league's situation is actually not as good as people think."

But she just mentioned it.

Then he continued to introduce:

“The second thing that was discovered was the Chaos Mystery Lock, which was hidden on an abandoned planet in the star realm.

It was Lady Isabel who discovered the Chaos Mystery Lock.

And before that.

Do you know how chaotic this continent has become?

It is an understatement that a father and his son can kill each other, or that their friends turn against each other.

The life order of all races, including the human race, is close to complete collapse.

Just over three months since the Chaos Mystery Lock came into effect.

Irondor's population dropped by three percent.

This is a very scary number.

During that time, people's mental state was indeed close to the stage desired by the gods.

Everyone was at a loss and didn't know where to go. They didn't even know what was happening. They could only feel that something had been taken away from them.

This is the scary thing about mystery locks.

Sometimes I'm quite puzzled.

The Scourge Mage banished the gods and cleansed the realm, but did not completely deprive them of their authority.

This gave the gods a chance to fight back.

Regarding the follow-up processing of the chaotic mystery lock.

I actually don’t know much.

There are also various versions of gossip circulating within the alliance.

There is a saying that——

Ms. Isabel ate the Chaos Puzzle Lock on the spot!

These are the exact words of my mentor.

But I'm not sure if what she said about 'eating' was a metaphor or a real thing.

After that.

The effect of the Chaos Mystery Lock has also been greatly weakened. When reflected in the lives of ordinary people, at most, their living behaviors are relatively debauched——

But this is compared to the previous effect.

This is nothing.

On the contrary, Ms. Isabel herself seemed to be more affected.

She became a little nervous and a little crazy.

at the same time.

The remaining power of the Chaos Mystery Lock is more concentrated on the mages.

Especially the Alliance Mage.

So you can always find mages behaving in all kinds of strange ways.

I'm not trying to defend myself.

Maybe mages are naturally a perverse group.

But the impact of Chaos Enigma Lock on us is also real.

If one day you find that you have become a pervert.

Don't lose heart either.

It's probably no fault of your own.

It’s all due to the confusing mystery lock! "

Margaret said seriously.

Matthew thought about it carefully.

I found that there seemed to be no loopholes in what she said.

The information in this part is extremely valuable.

Matthew not only memorized it in his mind, but also took out his magic pen and took notes.

"If Isabel is what she is now because of the Chaos Mystery Lock, then it's really hard for the Alliance to attack her."

"But last time Ekmund and I talked about Isabel's drastic change in temperament, he kept silent about the Chaos Enigma Lock."

"He can't possibly know less than Margaret, right?"

Matthew thought secretly in his mind.

Ekmund may have deliberately concealed it, or he may have deliberately induced his feelings of hostility or fear toward Isabel.

Or simply, she doesn’t want anyone close to Isabel to be around her.

Then speculate further.

Is Ronan's banishment also related to Ekmund's obstruction?

Matthew didn't know.

The water between legendary mages was too deep. He just wanted to get some benefits, listen to gossip, and then stay away from them.

And in Margaret’s subsequent description.

Matthew also learned that the Seven Saints Alliance could not find the final "Civilization Mystery Lock" no matter how hard they searched.

In the end I had to give up.

However, the impact of this mystery lock is relatively small. After all, it does not affect the dominance of the alliance and will not cause much damage to the lives of ordinary people.

At best, productivity levels have stagnated.

Under the premise that Irondor has a powerful barrier package of the main material world.

No matter how prosperous the outer plane is, it is difficult to invade.

And to this day.

The gods even seemed to have taken the initiative to cancel the civilization mystery lock.

The smoke of war is a clear proof.

After listening to Margaret's long narrative.

Matthew rubbed his sore wrist and put away the dense notes properly.

"By this knowledge, I mean the three major mystery locks, including the history of the Blood Flag Kingdom. Did you get them all in the Great Library?"

he asked.

Margaret nodded happily:

"What? Are you interested? Do you want to introduce my best friend to you?"

"Her knowledge instillation techniques are top-notch!"

Matthew mused:

"It's okay if you go there and read by yourself."

Margaret blinked:

"It's not that simple."

"Books in the big library are not allowed to be borrowed. They can only be read in the library. But this process is not that easy. You will know if you try it once."

"Believe me, making money and then purchasing knowledge infusion is the most cost-effective way to improve, bar none!"

Matthew thought for a while:

"Actually, there is another way, that is, you buy knowledge infusion and then share it with me orally."

"I can pay you some points."

Margaret shook her head and said:

"This method is theoretically feasible, but in reality no one will accompany you to play like this."

"Mages who are willing to buy knowledge infusion are either not short of money, or like me, they have already paid off their debts through ordinary ways of making money."

"The most important thing is that mages are a group of guys who are particularly afraid of trouble. The process of sharing knowledge is too long. After all, there are only a few who are good teachers."

Matthew thought the same thing.

He indeed did not find any relevant content on basic knowledge remediation in various training courses in the league.

Perhaps these things have to be found in the magic academy that trains mage apprentices.

For more advanced knowledge, you can only rely on yourself to read in the big library or purchase knowledge infusion services.

The two of them walked and talked like this.

Along the way.

Engineer Margaret physically lined up four "minefields".

Less than three hours.

They arrived at the end of the spider tunnel.

And in this process.

Matthew also discovered the secret of the spider tunnel.

Every ten steps they take in the tunnel, the effect of "Spider Walking" will be triggered on their bodies.

This spell increases walking speed extremely quickly.

The efficiency is almost equivalent to that of a walking person driving "shrink the ground into an inch" all the way.

This is an amazing effect.

Matthew guessed that this tunnel was used by the Blood Banner Kingdom to transport troops during special times.

If similar tunnels were spread throughout the Blood Banner Kingdom.

Then this country's local war potential is undoubtedly very terrifying.

In order to study how the "Spider Walking Technique" is solidified in the tunnel.

Matthew pried a few bricks from the wall that were obviously magical and went back to study them.

The end of the tunnel.

The two passed through a trigger-type secret door.

The scene in front of me suddenly became clear.

They were currently on the mountainside of a gray-black volcano.

Head up.

Thick black smoke lingers in the crater all year round.

The old castle slightly below the crater was hidden in the black smoke.

The special landforms carved out by magma are filled with a strong smell of sulfur.

And looked down the mountain.

A majestic city rises from the foot of the volcano, extending from the foothills to halfway up the mountain.

The architecture of that city is full of purgatory style, with round towers and towering construction platforms everywhere.

…

"Hint: You discovered the "City of Volcanoes."

You discovered the castle "Red and Black"!

You discovered the Purgatory Tower, the Land of the Sky (Construction Platform) and the Evil Tree of Purgatory..."

…

The Volcano City is the capital of the Blood Banner Kingdom.

There are a large number of tieflings and infernal humans living here.

The old castle "Red and Black" is the origin of the Blood Flag family.

It stands in the east of the crater.

From a very high position, you can overlook the capital city at the foot of the mountain and the endless plain of purgatory below the mountain.

The two of them had already carefully studied the map given by Lei Jia before.

After leaving the tunnel.

Margaret quickly fired an "Invisible Sphere".

The two walked along the rugged mountain road towards the crater.

The cemetery of the Blood Flag ancestors is located on the back hill of the castle, only one step away from the crater.

If you take the normal path, you need to cross the atrium of the castle and pass through a densely guarded stone forest to reach the cemetery.

But Rhaegar's map gave a path that could go around the crater.

But this road is also difficult to walk.

In addition to the harsh terrain, this area is also dotted with a large number of quasai demons and daemons.

They are all slaves of the Blood Flag family, wandering here under the orders of the people in the castle, and vaguely blocking every road leading to the cemetery.

Fortunately, Margaret is not only strong, but also has endless ways to deal with various situations.

The two of them passed through the area densely populated by demons without any danger, and arrived at the crater of the volcano.

Walk here.

Matthew could even hear the boiling sound of magma in the belly of the volcano.

This volcano is not only an active volcano, it is very active.

"Red and Black" and "Volcanic City" can survive frequent volcanic activities. There is a high probability that there is some way to guide magma.

The two walked around for a small half circle.

Soon we arrived at the area surrounding the cemetery.

This place is shrouded in billowing smoke, and it is not an exaggeration to describe it, but a conservative statement of objective facts.

There is no devil wandering in the smoke.

But the entire cemetery is surrounded by "Purgatory Evil Trees" with hideous trunks.

The evil tree of purgatory will devour everyone who comes close. Even the legendary strong ones will find it difficult to pass through here smoothly.

As for wanting to fly over these evil trees, it is even more of a fantasy.

According to Matthew's perception.

This evil tree is integrated with the cemetery. When you try to fly upward and over the evil tree, the evil tree itself will grow rapidly to intercept you.

Although the cemetery was not laid out as a dedicated ceremonial site.

But its defense capabilities are hundreds of times stronger than Matthew's small cemetery!

When the two of them carefully walked through the smoke and approached the evil tree area, Matthew took out the three tubes of blood left by Rega.

He smeared one tube of blood on his and Margaret's palms.

Then the two of them extended their palms to the front.

Step by step, we approached the densely packed tree wall.

Rhaegar has the blood of the high demon Memphist. In theory, this blood has a certain suppressive effect on the evil tree of purgatory.

as expected.

After the tree wall noticed that there was life approaching, it did not immediately surround the two.

Distorted faces appeared on the bark of the evil tree.

Their branches, as hard as rocks, hung softly to the ground, clinging to the trunk and the ground like vines.

The twisted faces stared at the two Matthews coldly.

There is only a gap of about 20 centimeters between the walls of evil trees.

Matthew boldly inserted his bloody palm into the gap.

The evil trees on both sides suddenly softened sharply.

The twisted faces on the tree trunks showed panic expressions. They let out silent screams, and even the tree trunks fell to the sides like a crowd moving away.

A half-moon-shaped crack appeared in the middle of the tree wall.

Matthew and the two took the opportunity to get in.

With Rhaegar's blood.

They crossed eight tree walls in a row.

And just as they were walking towards the ninth tree wall.

Suddenly, a strange cry came from the sky.

Margaret pulled Matthew to her side, and the invisible sphere instantly opened!

Two seconds later.

A demon riding a giant mechanical bat flies over the tree wall.

As the bat flies, it sprays gray-white powder downwards.

Hoo ho ho.

The powder fell down like snowflakes.

And due to the obstruction of the tree wall.

The smoke from the crater can no longer be seen much here.

Visibility is greatly improved.

Both of them were a little nervous!

None of them were sure if the powder had anti-invisibility capabilities.

But fortunately, the devil in the mechanical bat doesn't seem to care about what's going on underneath.

After dusting the powder.

He went in the other direction without looking back.

Matthew breathed a sigh of relief.

But very quickly.

He discovered that after the white powder fell, the nearby Infernal Evil Tree became more active.

He glanced down.

"No, Rhaegar's blood is almost dry..."

He looked quickly at Margaret.

Nervousness was also written on the latter's little face.

However, she still reached out to catch some white powder and observed it.

A few seconds later.

She scattered the powder on the ground in disgust.

"It's bone meal."

Margaret clapped her hands:

"The Blood Flag family uses fine bone meal to raise the evil trees of Purgatory. No wonder these evil trees grow so well!"

"Let's go while these trees are eating!"

Matthew's heart moved when he heard this.

The two of them quickly crossed the last tree wall.

He calmly grabbed a handful of bone meal from the ground with Astra Claw and brought it back.

After successfully crossing the last tree wall.

The detailed information of this bone meal also flashed on the data column.

…

"Volcanic Bone Powder: It is blended from volcanic ash, sulfur essence and biological ashes, and can be formed by injecting a small amount of astral light.

Purpose 1: Regularly raising plants with volcanic bone powder can make the plants grow more than 20 times faster, and have a very high probability of having an "animal template";

In addition, volcanic bone powder can make the land more fertile and has a strong nourishing effect on specific plants.

Use 2: Bathing the undead with volcanic bone powder can strengthen their soul fire and improve their level.

Undead who take volcanic bone powder for a long time will have stronger bones and can greatly improve the level of the undead's "natural armor". "

…

It's a good thing.

If it weren't for the worry that grabbing food from the evil tree's mouth might trigger an alarm.

Matthew wanted to scrape all the ashes off the ground.

The effect of this thing is much stronger than the Druid's green growth liquid.

The strong point is that plants spawned by bone meal are not considered "creations that go against nature."

"If you have a chance, you must get the formula for this bone meal. All other raw materials are easy to obtain. Only the light of the astral world is a bit troublesome, but it is not without room for maneuver."

"The blending ratio is troublesome. If you configure it one by one yourself, the efficiency will be too low."

Matthew thought to himself.

As for the biological ashes, he plans to build a "skeleton portal" in the cemetery when he returns.

This thing is not cheap, but it can regularly recruit skeletons from the negative energy plane into the cemetery.

Those with good quality will stay and serve as reserve forces for the Skeleton Soldiers.

Those with poor quality can only contribute to Matthew's tree planting career.

Thoughts are fleeting.

Matthew carefully looked at the scene in his cemetery——

There was always a thick fog inside the cemetery, and visibility was also very low.

The two entered through the tree wall on the west side of the cemetery.

Follow the map directions.

This place is only a few hundred meters away from the "Sacrifice Room".

However, there are at least three Blood Flag family graves along the way, and the number of traps nearby is much more than in the Spider Tunnel.

the most important is.

In such a place, Margaret's elimination method is difficult to come in handy.

Because it's easy to trigger an alarm.

Matthew took out the amulet given by Rhaegar and wore it on his body.

The two used magic to detect traps and mechanisms along the way, and carefully avoided all potentially dangerous places.

Twenty minutes later.

They slowly passed by the grave of Grandpa Rega or Grandpa Rega.

The map shows that there are two more high-risk areas ahead.

The atmosphere in the cemetery was very depressing.

Even Margaret's little face showed a little nervousness.

It can be seen that this place of murder brings huge pressure to people.

The two of them touched each other for another half hour.

Finally, we passed the most dangerous areas shown on the map.

A building with a pointed top appeared in the heavy fog ahead.

The building is constructed somewhat like a pyramid.

But the base is sunk into the ground.

This is the entrance to the underground mausoleum of the Blood Flag family.

All tombs must be entered through this place.

The two of them wandered around the entrance for a while.

Because the fog is really too heavy.

Their perception is extremely blocked.

I just took two steps towards the entrance.

At the corner of the stairs going down, a skeleton suddenly appeared out of nowhere!

…

"Warning: You encountered the "Undead Guard (LV16)" of Blood Flag Cemetery!"

…

"who are you?"

"Why are you in this cemetery?"

The undead guard shouted sharply.

Matthew hurriedly raised the amulet in his hand and said according to the prepared lines:

"We are descendants of the Blood Flag family, and we came here specifically to worship our ancestors."

The undead guard looked at the amulet and said in a daze:

"To worship our ancestors, just look at the tombstones on the ground."

"How did you get here?"

Matthew wanted to quibble.

But Margaret stepped forward generously and held the bone hand of the undead guard, with a pair of big watery eyes full of admiration:

"Wow, you are Mr. Randall, the legendary most powerful guard in the cemetery, right?"

"I have heard many elders mention you. I saw you today. You are indeed very handsome!"

Matthew glanced at the skeleton's waist.

I found an inconspicuous wooden sign hanging on it——

Randall Annon.

The skeleton looked a little at a loss:

"I'm Randall, do many people really mention me outside?"

"Speaking of which, I have forgotten all the heroic deeds I have done during my lifetime. Can you tell me about them?"

Margaret said with a smile:

"Of course, but before that, can you sign your name for me?"

"You are the hero I admire the most."

Said.

She took out a piece of pure white paper and eagerly handed it to the undead guard.

Randall hesitated for a moment, and then took the quill under Margaret's expectant eyes.

He quickly wrote his name on the paper.

"Now, you can tell me..."

Before the undead guard finished speaking, Margaret took the piece of paper, shook it slightly, and then gave a stern order:

"Randall, kneel down!"

In an instant.

The paper became a heavy parchment.

There were many dense words on it, and at the bottom was Randall's signature.

Matthew glanced.

This is a slave contract!

"No!"

"you cheated me……"

Randall made an angry sound, but his body knelt down honestly.

Margaret proudly turned the contract to Matthew:

"Do you see it?

This is also one of the contents of the practical class.

When you encounter an enemy who is not very smart, a slave contract prepared in advance and packaged with disguise can solve many problems.

But the prerequisite is that it must be in purgatory or a plane close to purgatory.

Because the contract field is one of the core areas of purgatory, the creatures here are more subject to the effectiveness of the contract than elsewhere.

Even if the enemy in the main material world signs a contract in this case, it will be difficult for it to take effect because the laws there are more complete.

But Purgatory is different. The law here is that the power of contract is above all else. "

Matthew nodded to show that he had really learned this time.

Margaret does have a lot of useful information.

When I think about it, this is the last lesson.

Matthew's heart was filled with regret.

present.

Margaret ordered Randall to clear the way ahead.

She immediately asked:

"How much do you know about this tomb?"

Randall said bitterly:

"My memory itself is very incomplete. I only know that I must protect this cemetery and can only patrol a small area around here. I cannot go further."

Margaret looked at Matthew.

The latter nodded slightly.

Indicates that this is a very common situation.

Although the undead guards in the cemetery are of high level, many of them are actually earthbound spirits.

They are the undead who were forcibly detained in the cemetery. Even if they are conscious, they are quite miserable.

Margaret asked a few more questions.

The content of Randall's answer was not nutritious.

The group of people could only move slowly towards the tomb.

Along the way.

Randall suddenly asked:

"Do you know what I did during my lifetime?"

"I mean, without lying, I really want to know this, can you satisfy me?"

Matthew thought for a moment.

He realized that this might be Randall's obsession as an earthbound spirit.

Answering or releasing the Earthbound Spirit's obsession is risky.

Once it fails.

It may lead to a crazy attack from the earthbound spirit.

The priority of this attack may still be above Margaret's slave contract.

Logically speaking, you shouldn't answer.

But on the one hand, if they successfully resolve the obsession of the Earthbound Spirit, they will have a greater probability of harvesting the Earthbound Spirit's legacy;

On the other hand, Randall's memory seems useless for exploring the cemetery.

Matthew and Margaret discussed it for a while.

"Are you sure your answer is correct?"

Margaret asked suspiciously.

Matthew said confidently:

"Incredibly sure!"

Margaret nodded in agreement.

Matthew then said to Randall:

"You were a tomb robber when you were alive."

Randall was shocked:

"How can it be!?"

"I……"

"It really is……"

Randall stood there in despair.

His soul fire suddenly burned violently.

There was a flash of white light.

Randall's bones were scattered on the ground.

He completely disappeared.

Immediately afterwards.

A golden key appeared among the skeletons.

on the data column.

…

"Tip: Your ability "Peer Smell" is in effect.

Fellow Smell (Grave Domain): You discovered a tomb robber (Randall), who is 1.2 meters away from you at the moment.

You have successfully solved the obsession of Earthbound Spirit Randall.

You have obtained the "Master Key" bequeathed by Randall.

Master key: Insert it into any lock cylinder to open it.

This key can open any magical, divine or physical lock including the legendary realm and the divine realm.

Available times remaining: 2/10.

Note: This is a strange object commissioned by the God of Travelers from the God of Craftsmen. The purpose is to open a strange cage in which the Maid of Pain and her sisters are imprisoned. "

…

There is such a good thing?

Matthew picked it up and handed it to Margaret.

Margaret's eyes lit up, but she still returned the master key to Matthew:

"Keep it for yourself."

"The place I'm going to next will only be full of battles, and I won't be able to use this key even if I take it."

"It's just a pity for my slave contract."

The two moved on.

The light in the crypt became darker and darker.

White mist seemed to seep in from the surface.

This feeling of being blocked is very uncomfortable.

Matthew took Rhaegar's blood in his hand, holding the amulet in the other hand, and followed Margaret closely.

"Sure enough, I feel too much pressure from things like tomb robbing."

Think so.

Suddenly another skeleton appeared in front of him.

This time.

Margaret couldn't help but use the "Dead Soul Holding Technique"!

The latter froze in place.

Margaret frowned:

"Such a high immunity. I can only freeze him for thirty seconds at most."

"Will you try this time?"

As she spoke, she handed Matthew a disguised blank slave contract.

"What is this? In-class testing?"

Matthew was surprised that Margaret still maintained her attitude towards class even in such a dangerous environment.

But her actions made Matthew relax a lot.

He rolled his eyes.

I have an idea in my mind.

After a while.

The skeleton was released from the immobilization technique and shouted loudly:

"Who are you?"

Matthew waved Rhaegar's blood and amulet in front of him.

The latter was immediately confused.

Immediately afterwards.

The soldiers and Renesmee he secretly summoned suddenly swarmed up and pushed the skeleton to the ground!

Renesmee was so powerful that the undead guard couldn't break free.

Matthew slapped the contract in front of him.

Then he ordered Renesmee to remove the skeleton's hand, and then signed the contract with flying colors.

"Lokening Desli".

no way.

Who makes the management of the undead guards in the Blood Flag Family Cemetery so honest?

Everyone has a wooden plaque with their name hanging on their waist.

Matthew didn't even need to use the name, he just signed the other person's name and that was it!

…

"Reminder: You and Lokening Desli signed a slave contract amicably.

The slave contract is in effect!

You have obtained a new slave "Undead Guard LV15"! "

…

See this scene.

Margaret showed a happy smile:

"It seems that you have learned to draw inferences from one example."

Matthew handed the slave contract to Margaret.

The undead guards looked at them dumbfounded:

"You are obviously not devils, how can you be more unreasonable than devils?"

Matthew wanted to answer him.

But at this time.

A strange power surged into my heart.

…

"Tip: Your wonderful use of the contract has profoundly implemented the secrets of the devil, and has been appreciated by the remaining consciousness of Baator, the Lord of Nine Hells.

You have officially entered the contract realm!

In return for getting involved in the field, you will gain two of the following three abilities -

1. The contract is supreme (no matter where you are, you can make the law of "contract above all else" take effect as if you were in purgatory).

2. Substituting concepts (when making a contract, you can blur the two concepts to complete contract fraud)

3. Overlord contract (when making a contract, you can put forward some overlord clauses appropriately, forcing the other signer of the contract to accept them)."

…
