The life of the doorman was even more dull than Wu Chong imagined.

Except for the first day of coming and touching people, the rest of the days are resting. People like the man in green keep the doorman for some special time periods, so most of the time, they have nothing to do.

Taking advantage of this time period, Wu Chong went to the warehouse to pick up a lot of things.

At the same time, he also went to the library of the young man in green, and as a high-level guest, he had this permission. In the library building, Wu Chong finally learned more news. For example, the immortals he had been asking about before solved the secrets of pollution.

There is also some common sense of Penglai Immortal Island.

The martial artists of this world, after the demon skill is sealed, will produce a lot of pollution in the body. These pollutants cannot be eliminated, but can only be mitigated by transfer, and there are two ways to mitigate them.

One is the suppression of internal strength, which Wu Chong has already explored.

However, this kind of method treats the symptoms but not the root cause, and the speed of normal people's cultivation of internal strength will definitely not be able to keep up with demon skills.

The second is the method used by the immortals of this world.

Life burns!

This method is mysterious, but in fact it is a kind of life exchange.

The essence of pollutant substances is indelible and must be attached to the negative energy of human beings. After perceiving this trait, a group of 'immortal elders' who wanted to survive thought of a way to transfer.

They put some ordinary people in captivity, and when their own polluting power explodes, they transfer these indelible forces to those ordinary people in captivity. For those ordinary people, even some cultivated martial artists, polluting substances are high-level energy that they cannot afford. Once the pollutant enters the body, it will frantically erode their lives, burning them out in an instant.

Even the weakest immortal leader, a pollution transfer requires more than a dozen lives.

Not to mention the strong ones.

The more powerful the 'Immortal Chief', the more lives will be consumed by the transfer.

This is also the reason why there is no war in this world, and the three immortal islands are high, not to maintain world peace, but because they regard the ordinary people in this world as their own crops.

"That's cannibalism."

Wu Chong put down the book in his hand and finally understood why Xu Zhou was reluctant to choose this path.

Putting down the book, Wu Chong opened another one.

This is a record of Penglai.

Penglai Xiandao is one of the forces with the longest inheritance. It is known as the three major immortal islands together with the abbot and Yingzhou, and it is the first batch of immortal forces in the world.

How it used to be the Three Great Immortal Islands, there is no detailed record in the book, but since the last hundred years, there are a lot of records. For example, the 'Xianmen Ceremony' that Penglai Immortal Island will hold every once in a while has a detailed description.

Penglai is located in the clouds, sitting and watching the prosperity of the world.

There are hundreds of immortal chiefs inside, and the immortal chief who is in charge of the immortal gate ceremony is an elder of 'no desire' foreign affairs, and his strength is unfathomable. In the eighty-eighth year of Penglai, there was a gang of 'no disaster' immortals who provoked each other and were killed.

"Desireless?"

It was the first time that Wu Chong knew about the realm behind the disaster-free realm recorded in the book.

The three old things that hacked him at the beginning were so strong.

Although for him now, demon skills are not so valuable, but the losses he has suffered can't be counted! And his Aoki Gong can be resold outside, which is different from the demon skills seen here by the man in green. The demon skills here are all marked by power, and if you sell them, you will be traced.

"It's easy to do when you know the realm."

Wu Chong read some more information about Penglai, and then threw the book aside.

"Mr. Wu, there is a task on Childe's side......"

The voice of a servant came from outside the door.

"Got it."

Putting down these books, Wu Chong got up and walked out.

Enjoying the benefits of others, it is natural to pay a price, which Wu Chong has been prepared for.

Three days later.

Wu Chong returned to the house.

A simple assassination mission where the enemy is a three-phase door.

These big people in White Deer City are amiable on the surface, but behind their backs, their brains are about to be played. But for Wu Chong, none of this has anything to do with him.

He contributes and exchanges resources from the other side.

Fair trade, no bullying.

That's it.

Another half a month passed.

On this day, Wu Chong felt that something was wrong as soon as he opened his eyes.

The demon skill that had been condensed in his body for a long time had finally reached a critical point.

Aoki Gong.

It's the third floor!

In the next moment, the power in his body erupted like a volcano, and this power raged wildly, quickly eroding his entire body.

Countless gray powers spawned from this power and began to affect his body.

Sensing this change, Wu Chong suddenly stopped his movements and began to concentrate on dealing with this suddenly growing force.

"The three internal skills have gradually become unable to suppress this force, and I need more powerful internal skills to do it."

Wu Chong struggled to control this force.

As he ran over and over again, the number of marks on his body began to increase rapidly. The gray marks condensed by this kind of demon skill quickly spread all over his body, and those demon skills that spread in his body were slowly absorbed under the traction of the mark.

The hidden dangers brought about by the breakthrough have finally been suppressed.

"Unless it is transferred, if it goes on like this, I will sooner or later follow Xu Zhou's old path."

Sensing the thirty new marks in his body, Wu Chong's face was a little gloomy.

Demon skill is a double-edged sword.

Don't look at the fact that he now has more than thirty marks, but these marks are all hidden dangers, and every time he calls it, he is one step closer to going crazy. Now he could feel a large amount of disease gray mist gathered on his body. This kind of thing will kill people if it explodes completely.

"The way to burn life is to cure the symptoms but not the root cause, even if I want, there are not so many people who come to transfer me."

Wu Chong thought about the solution.

After thinking about it for a while, I finally returned to the goal of internal strength.

He always felt that if he wanted to really solve the hidden dangers of demon skills, he still had to rely on internal skills.

Maybe in the field he hasn't touched, there may be some special internal skills.

"Someone."

Thinking of this, Wu Chong made a decision.

"Mr. Wu."

As the object of the focus of the young man in green, Wu Chong is equipped with a group of subordinates who serve him.

"Go to Zhuang Kun and ask for a handwritten book from the Library Pavilion."

The number of times Wu rushed into the library this month had been used up.

But it's not a big problem, doesn't he know Old Man Zhuang? This relationship doesn't have to be in vain. Anyway, it's useless for the old man to save so many times, so it's better to lend it to himself.

"Yes."

The subordinate quickly retreated.

When there are no tasks, they are really doing a good life.

After a while, Wu Chong took the handwritten book of the green-clothed boy borrowed from Zhuang Kun and stepped into the library again.
