Why do they exist? Isn’t it because after the Human Realm Evil Demon Crystal is purified, it can become a common regional evil demon crystal? Dozens of Human Realm Evil Demon Crystals can obtain dozens of regional evil demon crystals as long as they are purified, and the transaction consumption only requires no more than ten regional evil demon crystals, which is simply huge profit.

"Sir, how many human-domain evil devil crystals do you need to consume if you purify a piece of regional evil devil crystal?" Old Zhou thought in his mind, and looked at Tang Yu with a gaze and asked.

"How many human-domain evil devil crystals need to be consumed? What does it mean?" Tang Yu didn't quite understand what Lao Zhou meant. His purification was just based on a piece of evil devil crystal. Why did he need how many human-domain evil devil crystals?

"Sir, isn't the purification method you used to extract the pure evil spirit and demonic energy from the human domain evil spirit and demonic crystal and inject it into the consumed regional evil spirit and demonic crystal?" Lao Zhou asked in confusion.

"What's the matter?"

Tang Yu was stunned when he heard this. He had never heard of it. There was such a purification method. How could he submit it? It was batch filling! Compared to his purification method, it was many times simpler.

"Sir, I met a guy before, who could consume fifteen human-domain evil devil crystals and purify them to an area-wide evil devil crystal." Old Zhou simply took the bottom of Tang Yu and told Tang Yu completely his trump card.

Tang Yu believed that even if that person had such ability, Lao Zhou would definitely be at least 1 to 20, or even 30, to exchange it for the evil demon crystal from him, but compared with his ratio, it was still much worse.

Because he is simply a human-domain evil devil crystal, it is equivalent to an regional evil devil crystal.

Although there are not many purifications every day, Tang Yu believes that he has the ability and extracts tens of thousands, hundreds of thousands, or even millions of evil demon crystals a day.

"How much can he purify in a day?" Tang Yu really didn't want to use the word purification to get the evil demon crystal in this way.

"It's more than 30,000 yuan!" Old Zhou thought for a while and said.

"More than 30,000?" Tang Yu sighed in his heart, knowing that he still needed to continue working hard, and said, "Then can't you exchange it from him?"

"He is not in Weiyu City now?" Old Zhou smiled bitterly and said, "Since he suddenly left Weiyu City half a year ago, he has never come back, so I don't know where he went. Otherwise, how could I exchange it for people like Lu Gui or Luo Menbo?!"

First, he traded 100,000 regional universal evil devil crystals from Lao Zhou and gave him two million human evil devil crystals again, Tang Yu asked Lao Zhou to take him to the trading market in Weiyu City, wanting to visit here and see if there is anything you need.

After Lao Zhou obtained two million human domain evil demon crystals, he left again and helped Tang Yu arrange it to exchange for more common regional evil demon crystals.

Weiyu City is a big city with a population of billions, and the trading venues are very large.

The trading venues here are different from shops because they mainly trade in exchange for goods.

After all, things that can appear here are relatively precious. Sometimes they can’t buy them with evil magic crystals. People are unwilling to exchange the precious things into evil magic crystals, but choose what they need.

It is precisely because of this that this trading market is not very large in area, with only one street, less than one thousand meters in length, but it is crowded. There are nearly 100,000 people gathering on the streets less than one thousand meters, which is not considered the stall owners on both sides.

Such a place is a bit similar to the antique trading market on the earth, but it is definitely much more advanced than the antique trading market.

Walking among the crowded crowd, Tang Yu's eyes kept sweeping around the stalls on both sides. Although there were many precious things, to be honest, he could hardly use them.

"What's that?"

Suddenly, Tang Yu's eyes stopped in front of a stall wearing red clothes and the stall owner was a poor little girl.

This stall is very small, with an area of ​​less than half a square meter, and there is not much on it, only a green fruit.

The fruit looked a bit like green plum, but a mysterious aura was revealed on the whole body. This aura felt a bit like the power of the law, but Tang Yu did not expect what the law was.

There were three men standing in front of the stall, two of whom looked at the little girl with filthy light and kept making "tsk tsk" sounds, and they were obviously not a good thing.

The other one is a man who looks more steady. He is squatting on the ground and carefully studying the fruit. His eyes are filled with an extremely curious look.

"Little girl, I really need this thing and want to study it, but I really don't have the inner elixir of Kunyun Leopard on me. Otherwise... I will exchange it with you with other monsters and demon pills? Is the inner elixir of Xuanxuan Guiyuan Beast okay? That's a monster that is more advanced than Kunyun Leopard." The steady man looked at it for a long time, finally raised his head, looked at the little girl eagerly, and his tone was a hint of pleading.

But the little girl shook her head stubbornly, bit her lip lightly, and said, "I only need Kunyunbao's inner elixir, I want to save people."

"Little girl movie, the inner elixir of Xuanxuan Guiyuan Beast is worth at least more than ten Kunyun Leopard's inner elixir. We Brother Yun gave you face and were willing to exchange it with the inner elixir of Xuanxuan Guiyuan Beast. Otherwise, do you think this kind of garbage fruit can be exchanged for Xuanxuan Guiyuan Beast?" One of the two men who had been staring at the little girl with dirty eyes and suddenly said with a cruel face.

The little girl was obviously startled, and then she retreated, clasped against the wall, curled up into a ball.

"I...I don't want it. I want Kunyunbao's inner pill to save people. I don't want the Xuanxuan Guiyuan Beast." The little girl said aggrievedly with a hint of crying.

"Za Ling, shut up." The steady man showed a hint of dissatisfaction on his face, shouted fiercely, and then looked at the little girl kindly again and said softly: "Little girl, why not do this! Look at the inner elixir of my Xuanxuan Guiyuan Beast, it is more valuable than the inner elixir of Kunyunbao. It is also much more valuable than your fruit. Maybe it is even more attractive to use the inner elixir of Xuanxuan Guiyuan Beast to exchange the inner elixir of Kunyunbao, right? I think no one has come here!"

Tang Yu almost sneered. The three of them were obviously red-faced and white-faced. Although the steady man's tone was always soft, the gloom in his eyes was obviously visible that he was not a good thing at all.

The little girl was obviously moved.

Tang Yu frowned. Not to mention it, he felt that these three people were just cheating this little girl. Although he didn't know what the inner elixir of the Xuanxuan Guiyuan Beast was, he felt that with the appearance of these three people, they probably were not good things, and their value was definitely not as good as this green fruit. Maybe the little girl exchanged it and wanted to exchange the inner elixir of Kun Yunbao.

Secondly, this green fruit seemed to be very attractive to Tang Yu, making Tang Yu feel that it was always summoning itself, so Tang Yu really wanted to get this fruit, so naturally he would not let others snatch it.

Third, Tang Yu happened to have Kun Yunbao's inner elixir. Since this poor little girl needs Kun Yunbao's inner elixir to save people, then he exchanged it with her and just treat it as a helper. Anyway, it's useless for him to keep it.

"etc!"
