The entrance of the Eastern Federation Base is built between two high mountains, the names of these two high mountains are called Shuangsheng Mountain, the two high mountains of Shuangsheng Mountain are more than 3,000 meters above sea level, there are two guard towers on the top of the mountain, standing in the guard tower, even if you do not borrow any instruments and auxiliary equipment, you can clearly see the wind and grass within a radius of ten miles, and the field of vision is extremely broad.

Ten miles away, there is a rolling crater, this crater is called the Yuhuan Mountains, the Yuhuan Mountains surround the Shuangsheng Mountain, and there is only one exit, that is, the Pass Mountain.

The pass mountain is facing the entrance of the base, and it is the only way to enter the Yuhuan Mountain and go to the Eastern Federation base.

Today's earth, mutant creatures are rampant, although there are no high-level mutants within a radius of thousands of miles with the base as the center, but once out of the base, you will encounter some mutants without the slightest intelligence, most of these mutants are below the D-level strength, and can be classified as weak-level monsters, with the strength of seven or eight meters per second, and often attack the base in groups, so every once in a while, the base will send D-X troops to clear up a few times, and come to train troops to maintain the peace of this area.

These mutant creatures without the slightest wisdom have a brutal temperament and no sense of crisis, as long as they see an active lifeform, they will go up and attack, Gu Shuang just walked out of the base and encountered the siege of these weak-level monsters.

At this moment, Gu Shuang had a big magic knife and a gourd hanging around his waist, wearing a black suite, carrying a simple bag on his back, and holding a small notebook in his hand, while in front of him was a group of monsters with a lion's head, a wolf body, and blood-red pupils like a wolf and not a wolf, like a lion and not a lion, were surrounding Gu Shuang in the middle, grinning his teeth, ready to attack.

This monster is called the wolf lion beast, the body is two meters long, the weight is about three hundred catties, the danger level is below the D level, and it can be dealt with with with a gun.

Gu Shuang is investigating why they mutate and how they reproduce.

"This kind of monster should not have an awakening Yuan Wheel, and they can't absorb the energy in the air without the Awakening Yuan Wheel, but they still mutate, and it seems that as long as the dark particle energy comes into contact, it will make people mutate..."

Gu Shuang carefully observed and studied, he ignored the danger, and stood in the center of the wolf lion beast herd, calmly doing his own thing, as if these terrible monsters around him were air.

"Roar!"

A wolf lion beast couldn't bear it anymore, it roared and fiercely pounced on Gu Shuang, and when its accomplices saw this, they also moved in unison and launched an attack on Gu Shuang!

At this moment, the sky is full of the shadow of the wolf lion beast, ordinary people face such an attack, even if they have a gun in their hands, they can't parry, but Gu Shuang's expression is very flat, I saw Gu Shuang 'snap' the black diary, and his left hand pulled the big magic knife, only to hear the flash of the brush knife, and when Gu Shuang's big magic knife was returned to the sheath, this group of wolf and lion beasts that were still in the air turned into boxy pieces of meat, and they rained down from the air like raindrops.

"It can only roar, it doesn't break the limit of thinking, it's the same as the beast before the mutation, but the strength and speed are much stronger...."

After Gu Shuang opened Heisi's diary and recorded a stroke, he squatted down and released his mind wave to check the corpses of these wolf lion beasts.

Through the thought frequency, Gu Shuang found that only the skin layer on the surface of the body of these wolf and lion beasts was mutated, and these cells had turned into mutated cells like black holes, and the structure had completely changed, but some of the muscles and internal organs inside still remained their original appearance.

"This is an incomplete mutation, it seems that the mutation process is indeed as I expected, it is a long time, after sixteen years of evolution, the external image of this group of wolf and lion beasts has changed, but the inside has not yet mutated, but over time, as long as they are given time, when they also change inside, I believe their strength will gradually improve..."

Gu Shuang stopped his pen and looked at their brains with his thoughts again, and was shocked to find that the brain tissue cells of these wolf and lion beasts had begun to mutate.

"Brain tissue mutations are occurring, and cell mutations on the surface of the skin have been completed.... If their brain tissue mutations are complete, will they awaken their minds? ”

Gu Shuang was a little unsure, after he recorded this information, he put away the diary, pulled out the big magic knife, and used the big magic knife to pick a piece of wolf lion beast meat.

"If this thing is eaten, will it cause mutation?"

Gu Shuang looked at the part of the organization of the wolf lion beast on the tip of the knife, doubts flashed in his eyes, and after thinking about it, Gu Shuang raised the fire and prepared to roast a piece of wolf lion beast's meat to eat.

He has a mass core, and if he finds something wrong, he can use the mass core to suck out some toxic substances at any time, so Gu Shuang is not worried at all, this thing will damage his body.

About half an hour later, the roasted golden wolf, lion and beast meat was freshly baked, and Gu Shuang didn't think about it, so he took a bite of it.

"Huh!? It's unpalatable."

Expecting that the taste of barbecue in the high school entrance examination did not appear, Gu Shuang felt like he was eating a piece of charcoal, and felt unpalatable and bitten to death, but even so, Gu Shuang gritted his teeth and spit out a small piece of his stomach, ready to experience its transformation.

After throwing away the other meat, Gu Shuang closed his eyes and began to savor the piece of meat that he had eaten.

The structure of the human body, the way to obtain energy is simple and crude, after a small piece of the meat of the wolf lion beast was eaten by Gu Shuang, it first fell into the stomach and began to be decomposed by the stomach acid in the stomach.

In fact, after the Yuan Wheel awakened, Gu Shuang could use the Yuan Wheel to squeeze the energy in it, so that the digestion speed could be accelerated and the eating efficiency could be improved, but Gu Shuang did not choose to do that, thinking that he wanted to experience this process and analyze its difference.

When that small piece of wolf lion beast's flesh began to be decomposed by stomach acid, a strange scene appeared, some invisible, but indeed existent, energy, began to erode Gu Shuang's stomach pouch, wanting to change the structure of the stomach pouch.

"It seems that eating the flesh of mutated creatures will also cause mutations, mainly because the cells of mutated creatures contain dark particle energy..."

With a move in his mind, Gu Shuang squirmed his stomach through Yuan Energy, causing nausea, and after spitting out the undigested meat, the mass core of his right hand moved, and the harmful substances and dark particle energy in his body were all inhaled into the mass core and turned into pure energy.

The mass core is extraordinary, and the ontology is life, which is probably an existence that has undergone mutation or evolution, so it is not afraid of the mutated effect of dark particle energy.

"Where does this dark particle energy come from? Is it from the universe? Or do you say...."

After stepping on the fire for barbecue, Gu Shuang took the diary, looked up at the lead cloud above his head, and began to think about the source of the dark particle energy.

After the catastrophe, the lead cloud above the head persists all year round, like a planet about to die, the last breather.

"There are so many unknowns, too many mysteries, I need to solve them one by one...."

Gu Shuang closed his diary and returned to the road with the Great Demon Knife, preparing to investigate while looking for the light particle energy that could be used for human evolution.

This time, the destination was the territory of the plant species, the territory of the plant species was in the south, 10,000 meters away from the Eastern Federation base, Gu Shuang walked back and forth a few times, and said that he was very familiar with the road to the plant species.

Out of the pass mountain, it is a desert plain, the plain is vast and boundless, and the soil is dry and yellow and red, as if walking on Mars.

The name of this plain is Feixia Plain, the negotiation place between Gu Shuang and the patriarch of the Gangyi clan was on this plain, that day, Gu Shuang went to the meeting with a single knife, the patriarch of the Gangyi clan Yuan Tiangang handsome his own clansmen came, Gu Shuang in order to fight for the right to speak, and the master of the Gangyi clan, the six-winged tengu fought several times, the two sides came and went, the fight was dusty, the sky was dark, and in the end, Gu Shuang relied on the thirteen knives of the Shocking Hong to defeat the six-winged tengu life form and won the victory.

Later, Gu Shuang and Yuan Tiangang sat down at the negotiation table, and Yuan Tiangang was about to take back the quality core, but was interrupted by an unexpected mysterious woman.

Gu Shuang still didn't know what Yuan Tiangang and the mysterious woman said that day, but fortunately, the quality core was preserved.

At this moment, Gu Shuang revisited the old place, and couldn't help but think of the mysterious woman, and couldn't help but stop, frowning and thinking.

"On that day, Yuan Tiangang said that I had seen that woman, who was that woman?"

Gu Shuang recalled slightly, but the memories seemed to be broken, and he couldn't remember who the woman he met was, as if it was a memory in his mind, which was deleted unconsciously.

"Because it's one of the anomalous species, I just can't remember..."

Gu Shuang scratched his head twice, among the four major mutants on the ground, the special species was the most peculiar, Gu Shuang deduced that they came from the starry sky, because, there was a strange creature that hinted at him.

"Huh?"

Gu Shuang stopped suddenly, he clearly remembered that a strange creature had hinted at him, those special species were all from the starry sky, but at this time, he couldn't remember the name of that strange creature no matter what.

"Forget it, don't think about it..."

Gu Shuang shook his head and stopped studying this issue.

"According to classified federal information, there are five anomalies on Earth, of which one of them is counted as the steel family, and the other four are... Hey? ”

Gu Shuang's mind was confused, he had all these confidential information firmly in his mind, but for some reason, he forgot what the names of the other four special alien species were.

"How so?"

Gu Shuang's consciousness was wrong, and after thinking about it, Gu Shuang took out his bag, took out a silver watch-shaped communicator from his bag, put it on his hand, and prepared to contact the base to inquire about relevant information.

Some confidential materials of the Federation belonged to the jurisdiction of Sun Gan's information troops, so Gu Shuang directly contacted Sun Gan.

Gu Shuang's authority level is very high now, and as soon as he explained his intentions, Sun Qian ordered to help Gu Shuang retrieve the files of the special species.

But, strangely, something happened, when the people in the archive opened the file of the anomaly, they only saw a blank space!
