I can go back to the mysterious age

The light turned yellow and bright, and the lines on the magic box on his hand gradually became clear, as if they were a symbol made up of ripples on the water.

Card Xiu thought of the wisdom rune on his chest, which was a palm-sized black ouroboros with an overall "∞" shape. There are scales on the body surface, which slightly reflect a black-purple light.

The stripes on it are similar to those on the bottom of the magic box.

He couldn't help but recall the message of the Wisdom Rune.

Its name is Ouroboros, which is the Holy Grail of blood that brews the blood of immortality, and is also the rune of wisdom that guides the climb forward.

Ouroboros comes from the mysterious Oyin civilization, and is said to be one of the five cornerstones leading to infinite greatness and endless distance.

"So, the patterns on the magic box may be related to the five cornerstones in the legend of Aoyin civilization? Or are they simply a product of that era and have a unified aesthetic pattern?"

Card Xiu muttered a guess, but his intuition made him prefer the first one. So Ka Xiu directly opened his shirt.

Revealing a body with some slender and thin muscles under normal conditions, the skin has a jade quality, as if the surface is covered with a transparent body. When the aura is restrained, no one would think that this body is actually a violent and brutal fighting machine.

In front of him, on his chest, the symbol of the wisdom rune appeared.

Under the yellowish halo of the chandelier, it appears slightly black and purple.

Card Xiu glanced at the upper right corner. Behind the Ouroboros symbol of the Wisdom Rune, there was a long charging progress bar, which was already full. During this period of time, he had killed countless dark creatures, especially dead blood, and almost created a Blood Spirit Society. Naturally, it is enough to absorb the essence of disaster.

However, Kaxiu had already used the once-a-year improvement opportunity of the wisdom rune when he created "Golem Secret Martial Arts".

Therefore, the effect of the wisdom rune is temporarily on cooldown.

On the sofa, Ka Xiu carefully observed the pattern of symbols on the back of Coupan's Box, and then looked at the symbol on his chest. The more I think about it, the more I feel that the two are very similar and connected.

Under the light, the wisdom runes flickered slightly. Quietly, the black and purple Ouroboros logo seemed to move.

Card Xiu caught this momentary change fiercely, and the fighter's observation and reaction abilities were far beyond that of ordinary people. He was sure of his judgment, the Ouroboros symbol had just rotated slowly.

He narrowed his eyes and thought quickly in his mind. Ka Xiu suddenly thought of the Coupan's Box in his hand, so he grabbed the box's hand and moved it closer to his chest. Sure enough, the Ouroboros symbol that had always been stable on his chest started to rotate.

The scales on the body moved slowly, and the node where the snake's head bit the snake's tail also began to move on a fixed track, very slowly.

Ka Xiu's eyes became strange.

Wisdom runes generally do not cause any movement, either in normal times or when absorbing the essence of disaster. Only when he accumulates enough calamity essence and upgrades once a year.

The Ouroboros symbol will then begin its rapid spinning cycle.

"..."

Card Xiu couldn't come to a conclusion for the time being, so he decisively pressed the bottom of the box straight towards his chest. Visible to the naked eye, as the distance between the two gets closer, the Ouroboros spins violently and accelerates.

The black-purple light on the surface suddenly became intense.

The lines on the bottom of the magic box also lit up, as if in response to it. The blue-purple glow flickers, blurred and dazzling.

Snapped.

The two runes were finally stuck together.

Ka Xiu trembled violently, and he felt as if a hot iron was attached to his chest. Wave after wave of high temperature penetrated the skin and flesh, seeming to sweep through the entire body quickly.

In a trance, the location of the wisdom rune. It seemed that some liquid was being secreted continuously, hot and invisible. Penetrates from the body through the bones and viscera, and cuts through the muscle membrane.

Finally it flows out of the skin and is absorbed by Coupan's box.

The moment the change occurred, Ka Xiu grabbed the magic box with his five fingers and could tear it off with just a thought.

But for some reason, he felt in his heart that it was best not to stop this change. There was a faint voice telling myself.

There are advantages to the situation at hand.

So Ka Xiu followed his intuition. He believed that a fighter's instinct of seeking advantages and avoiding disadvantages would never harm him.

Time passed by minute by minute.

Ka Xiu gradually shifted his gaze to the upper right corner of his sight.

The progress bar for accumulating the essence of disaster behind the wisdom rune is suddenly shortening, as if it has been squeezed out by something.

I don't know how long it took, but there was a clicking sound in my chest.

He looked down and saw that the indestructible body of Coupan's Box had cracked. Materials that were similar to metal but not like metal fell down one after another, decomposing and dissipating in the air. Under the light, it looks like a fleeting silvery mist.

A palm-sized book page fell into Ka Xiu's hands with a clatter, and the protective shell of Coupan's Box was unexpectedly unsealed.

He instantly contacted the rune of wisdom.

There must be an important relationship between the two, which leads to resonance and the Devil's Book falling out of the box.

Card Xiu took a deep breath and took another look at the wisdom rune on his chest. Fortunately, there were no weird changes.

He pulled his clothes back down.

Looking at the legendary devil's book in his hand.

This is a book with a black hard shell that feels extremely smooth, and the hard shell material is like an animal carapace.

On the surface of the Devil's Book, a ferocious skull logo is vividly displayed, which seems to highlight the evil content in the book.

On top of the skull are five gems of different colors.

They are all diamond-shaped and only about the size of the fingernail of your little finger.

Five gems, three very dim. Only the front two lights up, showing a very charming warm color.

Card Xiu looked around at the appearance and found nothing else before slowly opening the page of the book. Wow… Wow…

Blank, blank, blank.

All pages are in their original colors and have no content at all. The paper pages are as thin as cicada wings, but quite tough. Ka Xiu pulled hard, and it was amazing that such a thin page did not change at all. It's just that no matter how magical the material of the book is, it's useless without content. Is this a blank notebook?

He clearly remembered that Black Peacock said that the devil's book in myths and legends recorded evil forbidden arts and maps of ancient ruins. As a result, the Devil's Book was obtained, but the reality disappointed Card Xiu. He couldn't help but feel a hint of regret in his heart.

All the calamity essence he had accumulated during this period seemed to have been consumed. Although it could not be used originally, Card Xiu still felt very short-changed. For the first time, he doubted his intuitive judgment and couldn't help but read the book several times.

However, all pages are still blank.

Kaxiu was not willing to give in, so he used various methods such as burning, water immersion and low temperature. He also called Feng Liusi Saint Feinan to help.

After struggling for an hour, there was no result.

Just when he was about to give up temporarily, the image of the shell of the Book of Devil appeared in his mind again. If there's anything unusual about this book, it's probably just skulls and gems. So Ka Xiu studied the shell for another half an hour.

Hard work paid off, and he actually found it.

The solution turned out to be.

Press the two shining gems with your fingers and inject energy into them. The person who created this book is a genius.

You can imagine the stringent requirements for unlocking book pages!

After Ka Xiu injected his energy, the two shining gems dimmed again, and the first two pages of the Wordless Book had more content. He didn't rush to look at it, but used his courage to test the other three dim gems again.

It has no effect, and the content of the book page does not increase.

Card Xiu pinched his chin and quickly thought that the Devil's Book might need to be charged to unlock the content. The charging of energy is obviously related to the wisdom runes that were running before.

In view of the fact that the progress bar of the nature of disaster in the vision status bar is exhausted.

Card Xiu thinks that the energy needed for the Devil's Book is probably the essence of disaster, or the spiritual blood transformed from the essence of disaster.

The calamity energy he gained from almost killing an entire Blood Spirit Guild was only exchanged for the charge of two gems. This made Card Xiu a little unhappy and at the same time he became curious about the contents of the Devil's Book. The more expensive something is, the more valuable it is, right?

Ka Xiu suppressed his curiosity and continued to think about the harsh conditions for use of the Devil's Book. If you want to see the content of this book, it is not enough to be charged with the essence of disaster. The person who uses this book must be a fighter among the secret martial arts practitioners.

In other words, it is a human being who is a fighter or above and can freely control his spirit. Therefore, dark creatures cannot. They are naturally unable to control the spirit, and can even be said to be the enemy of the spirit.

"Dark creatures cannot read this devil's book..."

Ka Xiu came to a simple conclusion, thoughts racing in his mind. Finally, I kept this guess in my heart, calmed down a little, took a sip of hot tea, and opened the book.

Only two pages of the Devil's Book appear after charging.

First page.

Ka Xiu took a serious look and immediately stayed where he was.

Golem! ! ! ! ! !

how come? !

His breath was stagnant, and his heart almost jumped out of his right chest. The dark creature formed by his own dark biological transformation is the golem. The source is the vascular mutation caused by the meteorite that last traced back to Black Rain Villa. When looking back this time, this mutation seemed to be triggered by the fragment of the door, which directly caused Card Xiu to evolve and go berserk during the battle, almost turning into a demon.

Logically speaking, the golem should have been uniquely born by chance. How could the Devil's Book have its contents?

Ka Xiu suppressed his shock and continued reading.

The content of this page seems to be an introduction to dark creatures like golems, and there is a ferocious and huge golem pattern on the side.

It was exactly the same as what Ka Xiu saw in the black cocoon.

Next to it is the introduction.

Demonic Colossus: A powerful physical monster born from endless disasters, ranging from four to ten meters in size, possessing terrifying brute force. It is the ultimate fighting machine that combines speed and power.

Ranked fifth among all dark creature ultimates.

"The final form of dark creature?!"

Card Xiu caught the key points at a glance, and combined some of the information he had obtained before, he integrated some of the intelligence.

Then draw conclusions based on the content in the Devil's Book.

Dark creatures are one group after another, and each group will have a theoretical king. But not all ethnic groups can give birth to the ultimate body. Perhaps only a powerful ethnic group has the opportunity to transcend evolution over a long period of time.

It can be called the ultimate body, it can be called the dark original body.

For example, Yumira, the legendary ancestor of blood, is a vampire.

Its image seems to be a huge terrifying bat. The so-called blood ritual of the blood clan is left by Yumila. It also prays for Yumila's power to purify the original blood.

In addition, there are the totem wizards of Shiwandashan.

Their power comes from the king hidden in the deepest part of the Hundred Thousand Mountains, the Totem King Caceres. The aura that escaped unintentionally while sleeping in the mountains changed the surrounding environment, causing animals, plants and even inorganic matter to mutate and produce totems.

There is also the Blood Spirit Society. Their high-level dead blood condenses into a resonance body, which is particularly like the prototype of the ultimate body.

Since Ka Xiu went back several times and traveled all over the world, he has not seen any trace of the ultimate activities of these dark creatures.

He thought of the legendary Totem King of the Hundred Thousand Mountains who had long since fallen asleep, the True Ancestor of Blood who had disappeared, and the death of the high-level vampires he encountered in the ruins when he last traced back. We have temporarily come up with a guess that the environment has changed. The world does not allow the original body to appear freely?

Or gaining terrifying power also comes with a price.

The price is a long period of sleep?

He took a deep breath and continued scanning.

The content on the page clearly introduces the various characteristics of the dark creature golem. Including but not limited to body structure, survival habits, eating habits, various combat states, and natural instincts.

Just like an encyclopedia, the analysis is quite comprehensive.

Sometimes Ka Xiu's heart moves when he reads the content. The core of his golem secret weapon is to imitate the state of the golem, whether it is the outbreak of battle or physical transformation. His fighting style was explored by himself, mainly relying on a combination of physical strength and boxing skills.

And now there is the exposition and explanation of the Book of Devils.

Can I try to stimulate the various fighting states of the golem and even its various talents and instincts in the golem state of the golem's secret martial arts? For example, the smell of blood is mentioned in the book page.

This is an instinct of the golem. As long as the enemy is stained with its own blood during the battle, the smell of blood will be found wherever he hides. Unless the distance is too far and the time is too long.

Card Xiu continued to look down, and he was still unsatisfied until the entire content of this page was over. He lacks knowledge about golems and needs this supplement. Only by knowing yourself and the enemy can you be victorious in every battle.

Ka Xiu obviously understands himself better now.

He raised his head and let his eyes go blank, as if he was digesting the excessive pressure accumulated from the information in his mind. After a short rest, Ka Xiu suddenly turned over a page, revealing the second page of the Devil's Book.

"The Secret of the South Dou", the map of the ruins where the secret is located.

Snapped!

He almost threw the Devil's Book on the coffee table.

When drowsiness came, he gave him a pillow, and Ka Xiu, even though he was slow, understood what was going on. The content revealed in the Devil's Book is the important information he wants to know most recently!

Could it be that this is a universal wishing book of knowledge? !

I had a sore back the next day, but luckily I was checked and given some medicine.

For muscle and bone pain, apply it everywhere.

I recommended a book by a friend, the title is "This BOSS is too outrageous", here is the direct link, if you are interested, you can read it.
