Guoyun: My system comes with Marvel's black technology

At the same time.

In the Super Trading Area, all three weapons and armor that Tang Xiaofan auctioned had the Castle Lord bidding for them.

And the frequency of bidding was very high.

Obviously, there were many people who could see the current situation clearly. So what if they were low-level weapons?

At this stage, broadswords and maces were divine weapons!

No matter how you slander them, there will always be people who know the goods and rush to buy them!……

"Tang Xiaofan!"

"Qualified to be my opponent!"

On a mountaintop somewhere in the God and Demon Continent, there stood a young man with his hands behind his back.

In his field of vision, a dozen wyverns about 20 meters tall were hunting a group of wild elves.

Perhaps because of the direct summoning, the wyverns, creatures at the top of the food chain in the world of Western fantasy novels, were not as invincible as described in the novels.

As larvae, his wyverns had very weak physical and magical defenses.

The concentrated acid sprayed was not powerful enough to scare even humble and weak creatures like wild elves.

On the contrary, when they saw the wyverns, the wild elves took the initiative to attack, as if they had seen treasure, with greedy eyes.

"Ogre, the strength is not much different from that of wild elves!"

"My wyverns are currently not strong enough to attack an ogre tribe."

"But, they will eventually grow up!"

"One day!"

""My castle will be stronger than Tang Xiaofan and stand at the top of the God and Demon Continent!"

The young man was very confident.

His flying dragon castle would surely be able to look down on the world!

Tang Xiaofan was just a roadblock on his path to growth.

Just kick him away!

……

On a boundless plain,

Bear Grylls is leading his ancient giant bears to hunt a herd of bison.

Compared to the first day when they were chased by the bison, his ancient giant bear team can now hunt these herbivorous monsters easily.

"Tang Xiaofan is one step ahead of me!"

"But soon, I will catch up with you!"

Bear Grylls is also full of confidence

"I have collected 100 soul stones."

"After this hunt, we can upgrade the military structure!"

He looked at the level 10 elite bison not far away.

He would take down this boss tomorrow at the latest.

As long as the soul stone exploded, his ancient giant bear could take off.

In his opinion, as long as he upgraded the military structure, he could surpass Tang Xiaofan.

……

In other parts of the God and Demon Continent, there were also many castle lords who were full of confidence.

They believed that Tang Xiaofan was only leading temporarily.

They would catch up sooner or later.

Because they had top-level troops!

They were the chosen ones!

……

After putting the item on the trading channel, Tang Xiaofan suddenly saw a friend request. He was moved and clicked on it for the first time.

It was a reply from Ke'er:

"Tang Xiaofan, is it really you? Ke'er was so happy. She didn't expect that she could actually add Tang Xiaofan as her friend. Hehehe!"

The next moment, another message came.

"Mr. Tang Xiaofan, Ke'er's army is the Dark Iron Dwarf, specializing in mining, smelting, and crafting equipment!"

"The castle is located in the underground world."

"There are stone mines and iron mines around."

"I have stored all the stones and iron ores collected from the stone mines. I can provide refined iron and stone materials."

"It is estimated that there are more than a thousand units per day!"

"Does Tang Xiaofan need it?"

Tang Xiaofan replied:

"I want both. What's the price?"

Ke'er:

"One unit of food for four units of refined iron, one unit of food for ten units of stone, do you think this is okay, Mr. Tang Xiaofan?"

Tang Xiaofan was stunned. He thought he would have to pay a little.

After all, refined iron is precious.

Unexpectedly, the exchange price given by Ke'er was lower than the market price.

Yesterday, he saw a price in the trading channel for one unit of food in exchange for three units of refined iron, and no one was willing to exchange.

Now, Ke'er is willing to use four units of refined iron to exchange for one unit of food for him.

What does he want to do?

Tang Xiaofan:"Didn't you see the price others have marked in the market?"

Ke'er:"Yes! But Ke'er wants to maintain a long-term cooperative relationship with Mr. Tang Xiaofan. If it is a fair price, when there is more refined iron in the future, you may not buy from Ke'er."

"Tang Xiaofan is so powerful"

"Being able to cooperate with you for a long time will also be beneficial to Ke'er's Black Iron Castle."

Seeing such a reply,

Tang Xiaofan couldn't help but label Ke'er as a shrewd businessman!

She seemed to have lost money.

But in the long run, she made money.

After all, Tang Xiaofan is recognized as the strongest castle lord. In the early stage, using the price difference of one unit of refined iron can establish a long-term cooperative relationship with him, which is very meaningful for investment.

In the middle and late stages, let alone the price difference of one unit of refined iron, even if a box of soul stones is placed in front of Tang Xiaofan, he probably won't be tempted.

Tang Xiaofan replied:"We can cooperate! I will come to you when I collect food!"

Ke'er:"Great!!"

Tang Xiaofan asked:"How did you smelt iron ore into refined iron?"

Refined iron is one of the materials for upgrading towns.

But so far, no castle lord has been heard of who can smelt iron ore into refined iron.

Originally, Tang Xiaofan thought that only his own blacksmith shop could smelt refined iron, but he didn't expect that Ke'er could do it.

Ke'er:

"Hehe! My dwarf accidentally stepped on a cockroach while mining, and unexpectedly, it dropped the blueprint of a smelting furnace. I have already built the smelting furnace, and as long as I throw iron ore into it, I can get refined iron!"

Stepping on a cockroach to death, the building blueprint dropped??

Tang Xiaofan was stunned.

His farmer had killed at least five or six hundred wild monsters in the past few days.

But he didn't even see the shadow of the blueprint.

"Cockroaches?"

Tang Xiaofan looked at his black technology castle.

He didn't know if there were any cockroaches in the castle.

If there were, he wanted to step on one to death to see if he could get the blueprint.

……

In the underground world of the Gods and Demons Continent, there is a level 2 castle.

In the mining area outside the castle, a dozen Dark Iron Dwarves are working hard to collect iron ore.

Above the castle yard, black smoke is billowing from a 30-meter-high smelting furnace.

Near the smelting furnace, there are several Dark Iron Dwarves who are constantly throwing iron ore into it. There is also a little girl wearing a pleated skirt and with a gray face standing next to her directing

"Everyone, work harder!"

"I found a great client!"

"He is the lord of the most powerful castle in the Continent of Gods and Demons!"

"We in Dark Iron Castle will soon be able to live a good life!"

"As you command, Princess Ke'er!"

The Dark Iron Dwarves worked even harder.

Mining, smelting... the sound of"Yo Hey" never ceased!

This is a hardworking army, so of course they have to be well fed and well-drinking!
