Qin Lang had collected the steel chains and steel ropes of the Flame Demon that Xiao Huo had slain before, because he felt that the value of those steels was good, but after entering this Black Tower, Qin Lang couldn't wait to throw away all the steel he had picked up before like garbage, because the tables, chairs and benches inside this Black Tower were made of much better steel than the weapons of the Flame Maniac Demon!

So after a glance, Qin Lang decided that the steel he had picked up before was actually garbage, and he should have thrown it away earlier.

Although the Black Tower is very large, there is only one "shopkeeper" in charge of transactions: both the shopkeeper and the teller.

However, the teller was dressed in a way that was not anything but extraordinary, and in terms of dress alone, he was on par with Hagrid.

This teller looks like a human nobleman, except that it has two goat horns on top of its head, which is the devil's sign!

The goat's horns on their heads are indeed the devil's symbol, but Hagrid said that the tellers in the Black Tower are not really devils, they are just "headdresses" with goat horns, so the goat horns on their heads are actually ornaments, and their bodies are devil's servants - devil's servants!

Devil servants are neither demons nor humans, although they appear to be fully human.

In fact, the true identity of the demon servants is that of human beings who have made a deal with the devil, and after their death, their bodies and souls may be "mortgaged" to the devil, so they become demon servants.

Devil servants have no consciousness or will of their own, they are only the most faithful servants of the devil, or they can also be called lackeys.

These demon servants, they were human beings when they were alive, because of the deal with the devil, they obtained the power or ability beyond ordinary people, so that they could survive better than everyone else in the human world, and they could live a high life, but these lives all need to pay a price, and the price is that after they die, they will become demon servants, and they will always do things for the devil and be the devil's servants.

"Honorable guest, what do you want to make a deal?" The servant was a handsome young man, but it had no breath of life on it, like the undead, but it was a little different from the undead, who wandered aimlessly, and the servant could faithfully do things according to the devil's will.

"What are the trading rules here?" Qin Lang asked.

"Equivalent exchange. The servant said.

"What is equivalent exchange?" Qin Lang asked.

"It's that you can trade your stuff with us in exchange for what you need. As long as we have, we can trade it. The servant explained very respectfully.

"Lingdan, can it be exchanged?" Qin Lang asked.

"Absolutely, and very welcome. The servant replied with a smile, "But I wonder what the honored guest wants to exchange for the elixir?"

"There should be no shortage of the best refined steel here, right?" Qin Lang asked.

"Of course. The demon servant said, and with a gesture of his hand, a cabinet on the top of this black tower was immediately opened, and then something flew out inside, which was a whole square piece of 100 refined steel, and it was a unique 100 refined steel in this world, and it could be used to refine magic weapons.

This piece of steel is about one cubic meter, black all over, with a clear texture on it, Qin Lang knows that it is a naturally formed steel pattern, this thing cannot be faked, just like the Dan pattern of the elixir, it is a natural thing, people who know the goods, at a glance, can see the truth through these textures.

Obviously, this is the real refined steel in front of him, and the things Qin Lang picked up before were all garbage in the garbage.

"How do I exchange the elixir?" Qin Lang asked.

"A superb elixir can be exchanged for such a piece of steel. The servant replied.

"Then come for a thousand yuan!" Qin Lang was not ambiguous at all, since it could be purchased with a spirit pill here, it was exactly what Qin Lang wanted.

Although the demon servant was a little surprised, he quickly calmed down, and only respectfully reminded Qin Lang: "Distinguished guest, are you sure that you want a thousand pieces? In addition, we need to test your elixir before we can trade, I don't know what you think?"

"The elixir is for you. Qin Lang directly threw a superb elixir to this demon servant.

The demon servant's eyes lit up, and he quickly examined this elixir: "It is indeed an excellent superb elixir, if you are willing to trade it for a superb elixir of the same quality, we can give you another hundred pieces of steel." ”

This demon servant is indeed a fair deal, and he knows that Qin Lang's superb elixir is in good condition, so he gives Qin Lang an extra hundred fast steel as compensation.

"Deal!"

Qin Lang directly handed a gourd superb elixir to this demon servant.

The demon servant took the elixir, and then naturally a piece of refined steel fell in front of Qin Lang, and Qin Lang directly included it in his own small world, and directly refined part of the refined steel and integrated it into his own small world.

Qin Lang's small world already has the prototype of the Kingdom of God, but he also knows that it is not the real world of the Kingdom of God, and if he wants to further improve his small world, he still needs to use more worlds to temper. Integrating into this hundred refining steel, it is quenched by the method of the five elements, the hundred refining steel of the second layer of this abyss is very special, and integrating it into its own small world can make Qin Lang's own small world more stable and enhance its "golden" nature.

One thousand and one hundred pieces of refined steel were all taken away by Qin Lang, and this first transaction was naturally completed smoothly.

What this demon servant said was right, the weight of a hundred refined steel was indeed several times heavier than ordinary steel, but this was not a problem for Qin Lang at all.

In addition, this first transaction is just a temptation, and the next transaction content that Qin Lang proposes is the real transaction: "I heard that you can trade anything here, but don't you know that you can trade Godhead here?"

"If you want to betray your godhead, we can make a deal. However, if you want to buy the Godhead, I'm afraid it will take some time because it is out of stock. The servant replied. It seems that the power of the Godhead can be purchased in this black tower, but because there are too many creatures who desire the power of the Godhead, it is out of stock.

Qin Lang didn't expect to be able to buy godhead power here, and even if he could buy godhead power, it must be some low-level godhead, and it was impossible to buy a godhead like a true godhead like the Golden Armor Divine Spirit.

Buying the power of the Godhead was not a temptation from Qin Lang, and he then asked: "Forget about the power of the Godhead, but I don't know if you can buy the power of the world origin or the small world of the monk here?"

"This ...... Distinguished guest, I am really embarrassed by your request. The demon servant really showed a puzzled expression, "The things you need are scarce. Of course, if you insist on these things, you can trade them, but you need to pay some special price. ”
