……

Fengqing Village, southwest corner.

The color of the sky here is noticeably darker than elsewhere, and a thick dark substance floats in the air, as if it is a pond of green algae.

Xu Mu and Liangchen soaked in it, and nothing happened.

For ordinary people, dark matter is the poison of mutation, but for the supernatural, this thing is the best tonic, the medium of control of the elements.

Xu Mu silently replenished his abilities while carefully observing the ancient tree that shook in the night.

Its withered trunk was glowing at this time, and it was psychedelic, and it involuntarily wanted to walk past.

His eyes were slightly condensed, it was attracting people to the past, why?

Seeing him look thoughtful, Liangchen swallowed a mouthful of saliva silently, and suddenly had a bad premonition in his heart.

Pollution sources, there are pollution sources in this village!

Xu Mu, is it for him to solve this thing?

Liangchen looked frightened and couldn't help but take a step back.

He is indeed a genius of the gold and silver firm, and his strength is also very strong, but if he wants to deal with a pollution source, it is indeed a bit immeasurable, if there is no absolute strength to suppress it, cleaning up the pollution source will be an extremely time-consuming process, and it will be a stalemate for three or five days, which is a common thing.

And the ability reserve of the first-order ability can't last at that time, or even three or five hours, because within the range of the pollution source, all creatures will be transformed into aliens, and when the darkness is thick to a certain extent, it will automatically summon white bone skeletons.

The supernatural needs to spend their minds to eliminate the aliens, and at the same time, they also have to purify the pollution one by one with special charms, which is too complicated and dangerous, so even if it is a first-stage pollution source, it needs a second-order anomalist to clean up.

And looking at this ancient tree with monstrous black gas, the dark moonlight that swayed and fell from time to time fell on the bricks and tiles, and even caused trembling.

Non-living organisms even have to mutate, what will be the quality of this source of pollution?

……

"The key to the source of pollution is not the ancient tree, I always feel that there seems to be something buried down there."

Xu Mu used his shadow ability to go deep under the tree, and after perceiving it carefully, he came to a conclusion.

He did not perceive the pollution on the body of the ancient tree, but sensed an extremely strong energy under the ancient tree.

It's like someone buried something in the roots of an ancient tree.

"Gotta find a way to dig it up."

"You're a psychic powerhouse?"

Liangchen swallowed a mouthful of saliva and looked at Xu Mu in surprise.

Being so far away, he could perceive it so clearly, and even the specific location could be found, which was a bit beyond his comprehension.

And isn't this guy playing with knives?

"Buzz!"

The totem buried in the ground seemed to sense that someone with an ability was approaching, so in the interval between the two of them, it automatically released a large amount of evil energy, and the billowing black gas spread to a hundred meters away, and many flowers and plants were covered inside.

Xu Mu's eyes condensed slightly, this was aware of their arrival, so the pollution source broke out in advance, do you want to prevent them from entering?

"It's self-conscious!"

Liangchen exclaimed, this pollution source has autonomous consciousness, it seems that the situation is even more serious than he imagined, this is a characteristic that can only appear in the three stages of pollution sources!

"Brother Xu, this level of pollution source is not something you and I can solve." , Liangchen's face was solemn, he had already retreated, and he didn't even want to stay for half a second, so he retreated back immediately, "Before the pollution has completely exploded, let's retreat quickly!" ”

Xu Mu was immersed in this thick darkness, the pores of his whole body were opened and absorbed, and when he saw that Liangchen was leaving, he dragged the other party by the hand:

"Let's go? Why go. ”

His expression was surprised, the source of the third-stage pollution was not a third-stage ghost, as for such a fuss!

"You don't have to worry about being polluted, of course you don't have to."

Charles glanced at Na Liangchen pitifully, the source of pollution in the third stage is indeed terrifying, even if it is only a prototype, it can also pollute the body of the supernatural person for a second time.

Normally, the body of each person with an ability has a limit to carry the ability, and if this limit is exceeded, or the purity of the energy absorbed exceeds the level that the body of the person with the ability can bear, then the person with the ability will mutate.

But where did he guess, Xu Mu would not be afraid of this at all, it would only make him stronger, and in just a few moments, his internal injuries would recover a lot, and this source of pollution was simply a moving blood spring!

Xu Mu turned his head and looked at Liangchen suspiciously.

Such a good place, he can't find it if he wants to, and you still want to run?

But the latter, at this time, was looking at him with the eyes of a monster.

"Brother Xu, you don't need elemental energy to protect your body, aren't you afraid of being infected!"

Liangchen couldn't break free, so he gave up struggling, his whole body was wrapped in earthy yellow elemental energy, and the darkness of the outside world was blocked out, unable to erode his body.

"Brother Xu, I think we should withdraw quickly, it's really too late if we don't withdraw!"

Liangchen looked around, those flowers and trees had changed at this time, the branches of the big trees had turned into sharp blades, the grass was covered with dense eyes, and even the surrounding wall tiles seemed to slowly stand up and take on a human form.

His voice was already tinged with a cry.

"There are a lot of strange ghosts, please bother my brother, help me lure them away."

Xu Mu pulled out the knife on his waist and said coldly.

He could feel the ground tremble slightly, and then dozens of skeleton aliens crawled out of the nearby ground.

These skeleton guards didn't attack, but obediently guarded around the ancient tree, obviously not wanting Xu Mu to get close!

In order to get rid of the source of pollution, he first had to approach it.

It's just that in the source of pollution, these strange ghosts can "come back from the dead", so he can't waste time on the strange ghosts, and only by solving the source can he solve the problem fundamentally.

And the existence of these strange ghosts, although it will not kill him, will be very troublesome, after all, now, in addition to being physically stronger, not afraid of pollution, there is no lethal ability, to deal with the strange ghosts, you still have to use that hunting knife.

"You don't need to do anything more, just attract some strange ghosts to attack me, and if you can't bear it, you can leave."

With another command, Liangchen was patted on the shoulder by Xu Mu, and then his eyes widened.

"Are you crazy? This is a third-order source of pollution! ”

"I know."

Xu Mu stared at Liangchen's eyes:

"So, can you help me get them away?"

"If you can't resist it, you can go first, but you must not sell me!"

He pulled out his hunting knife and stared at Liangchen viciously, he was very suspicious of this kid's character, and it was really not a wise choice to teach him his back, but there was no other way now.

Liangchen is dumbfounded, get rid of the source of pollution?

He didn't know where the confidence of this guy in front of him came from, and he actually wanted to take the initiative to drill into this source of pollution.

Playing with knives, is the spirit so bad?
