As he ran forward, Qin An's memory of this wolf beast also became clear, as if someone had suddenly opened a door of memory in his mind.

The Chinese wolf, also known as the Tibetan wolf and the Mongolian wolf, is a subspecies of the gray wolf. They are survivors of the Ice Age and originated about 300,000 years ago.

This wolf had been living on a prairie until the end of the world, and Qin An judged that this place should be somewhere in Inner Mongolia through the landscape of the characters in its memory, because he saw many yurts appearing in the memory images.

After the end of the world, some wolf corpses in the wolf clan turned into zombie beasts, and this wolf was bitten in the battle with zombie beasts, and finally awakened into mutant beasts. Obviously, the chance of mutation of a beast like a wolf is very high. Before the end of the world, animal protection organizations counted that the number of wolves in China was less than 2,000, but now mutated wolf beasts seem to be seen in many places.

Soon after the mutation, this wolf ushered in a second mutation, its body began to grow, and the gray hair on its body also turned white, becoming a second-class plains wolf, characterized by a very fast speed on the plains.

Later, new mutant species appeared in the Mongolian steppe, that is, those strange mutant insects, these insects took root in the soil, combined with the roots of plants, and then created countless mutated plants, and finally formed such a dreamy forest.

These things were the conclusions that Qin An came to after combining the memory fragments of the mutant wolf beast that had just awakened and the knowledge recorded in the book "Records of Creatures in the Last Days" that Guo Xiaomei gave him. In the ten days of the Beicang Dark Road, Qin An would read the book Guo Xiaomei gave him when he was fine on the boat, after all, he also needed to know more about the creatures of the end times, so that he could know what mutant beasts were dangerous and what mutant beasts were harmless.

Soon after, the mutant wolf beast ushered in the third mutation, becoming the mutant beast with the highest mutation level in the mutant wolf pack, and naturally became the wolf king.

Once, a third-level xenomorph zombie eagle came to the forest, and its existence posed a great threat to the wolves.

Therefore, when the zombie eagle landed to prey on its companions, the wolves launched a siege on it, and in the process of the battle, the wolf king evolved for the fourth time, his body became larger, his muscles became stronger, and at the same time, he had the ability to make a loud roar as a sonic attack, becoming a fourth-level blast plain wolf, and finally killed the zombie eagle.

There are many types of mutant wolf beasts based on wolves, and there are dozens of them recorded in the book of post-apocalyptic creatures, Qin An has read this part of the content, so he can also know the names of mutant wolf beasts according to their characteristics.

In this way, the Burst Plain Wolf has been living in the dream jungle as a fourth-level mutant beast, until a few days ago, a group of second-level zombie rats came to the north of the jungle, and the number of these zombie rats was tens of thousands.

When the rats meet the wolves, the difference in numbers makes it impossible for the wolves to defeat their opponents.

During the battle, although the fourth-level blast plain wolf killed thousands of zombie rats, it was also seriously injured in the end, and its body was infected with a large number of T viruses.

Half of the zombie rats were wiped out, and the remaining half scattered and ran away, and the fourth-level blast plain wolf fell in a pool of blood.

At this time, the wolf king was covered with the stench of corpses, and this smell made the other mutant wolves in the wolf pack very repulsive.

They roared at the Wolf King, wanting to lay him down and kill him, which was a natural occurrence between the biomes. Only the strongest individuals can become the wolf king and bring the tribe to more prey, while the unstrong wolf king can only be abandoned or killed.

The mother beast of the fourth-level blast plain wolf is an ordinary second-level mutant wolf beast that was bitten after fighting with the new wolf king, and finally could only use her teeth to support the injured fourth-level blast plain wolf and left the territory.

Today, a few days later, the fourth-level blast plain wolf is seriously injured and is about to starve to death, the TC virus in the body is completely unable to resist the excess T virus, and the mother beast can feel that it is about to die, which still has nothing to do with IQ, but a strange way of soul communication between beasts. And this way of communication does not have an exact meaning, but it can make the she-wolf feel the state of the fourth-level blast plain wolf.

The she-wolf needed food, and she also wanted to bring some food back to the dying fourth-level blast plains wolf, so she left her side.

The fourth-level popping plain wolf lay there dying, and in the end, what he ushered in was not death, but the fifth mutation under the combined action of the T-virus, C-virus, and TC virus in his body! Become a brand new level 5 mutant wolfbeast!

Level 5! It is a dividing point for mutant creatures, and from the fifth level onwards, these mutated creatures in the last days will not only have great changes in their bodies, but also their genes and souls will also have a qualitative change under the action of the T virus.

The so-called T virus is just a name given to it by humans, but in fact, the T virus is not a virus, it is much more magical than a virus.

It has vitality and energy beyond human imagination, and can combine with most of the material elements on the earth, and then form a new substance with various strange physical and chemical properties. And the creatures made of these substances are naturally strange.

In the book of Doomsday Creatures, there is no record of the fifth-level mutant creatures, which means that when the version of the "Doomsday Creatures" in Qin An's hand appeared, the doomsday biology team in the western Tibetan base had not yet discovered that there were already fifth-level mutant creatures in this end-of-apocalyptic world.

In fact, this is also normal, after all, fourth-level mutated creatures are very rare, let alone fifth-level ones? In other words, it is not easy to evolve to the fifth level. This wolf beast can do it, in addition to a little bit of luck, it may be more because of the proportion of its body material composition, which is different from ordinary wolf beasts, which causes it to finally evolve to level five again and again, which is actually a talent, which will only be revealed in the last days.

It was a coincidence that Qin An came, not long after the fifth-level mutant wolf beast had just mutated, his soul had parasitized into its body.

Qin An's current feeling was that this wolf beast had become more intelligent, although it couldn't be compared to the wisdom of humans, at least it should have already understood how to think about things.

I ran for a distance of about three kilometers, but it didn't take much time.

Between the several giant trees in front of her, the mother beast was confronting more than a dozen black mutant wolf beasts opposite, and the wolf roar just now came from the mouth of the mother beast.

No wonder I was attracted by this wolf roar, this can be regarded as a kind of cry for help from my mother.

Obviously, this she-beast accidentally entered the territory of the wolves when she was looking for food, and now she is no longer part of this beast tribe like her own wolf king.

Qin An stood by the big tree for a moment, and then shook his head helplessly, since he has become a beast, he must do something that a beast should do.

Thinking of this, Qin An stepped forward, walked to the side of the mother beast, and then bared his teeth at the dozen or so mutant wolf beasts opposite, and let out a weak roar.

He didn't want to look too rude and violent, after all, he was a beast.

The female beast found that Qin An's wolf body suddenly appeared in front of it, and she actually yelled at Qin An twice cautiously, and then retreated a few steps back, letting out a low wolf roar from her throat.

It seems that after this wolf evolved into a fifth-level wolf beast, its appearance has changed again, and the mother beast has made it unrecognizable.

What to do? I don't know how to wolf myself! I knew it would be better to learn a foreign language in the first place.

Qin An teased himself in his heart, and then casually roared at the female beast twice, what he wanted to express in his heart was: Mom, don't be afraid, I am your little Beibei.

When Qin An didn't expect it, the female beast seemed to understand her roar, relaxed her vigilance, and slowly walked to her side to smell the smell of her body.

What a hell!

Ignoring the female beast that was observing his body, Qin An set his eyes on the dozen or so wolf beasts opposite, and found that they seemed to be full of fear of himself like the previous female beast.

This is also normal, after all, he is now a fifth-level mutant wolf beast! It's not even recorded in the book of Apocalyptic Creatures, so it's impossible to figure out if it's the first one to evolve to level five in the apocalypse.

Standing in place with the wolves on the opposite side, looking at each other for more than ten minutes, Qin An finally lost his patience, he raised his head high, and found that there were not too many branches above here, and he could even see the moon! This round of bright moon is so full, the night is already very deep, right?

Opening his mouth, Qin An felt his blood begin to boil, and the muscles of his body were pushing each other, making his bones make a sound! Infinite power turned into a rhythmic breath, and finally into a wolf roar!

This roar resounded within thirty kilometers of Fang Yuan, causing countless birds to fly and countless creatures that slept at night to be awakened!

And where the sound wave passed, the trunk of a big tree with a diameter of half a meter was shattered, which shows how powerful this sound wave is.

The dozen or so mutant wolf beasts on the opposite side, as well as the mother beasts beside them, were completely shocked by this roar, and they all knelt on the ground one after another, and let out whimpering sounds, which meant that they surrendered to Qin An, who was also a fifth-level wolf beast, and the fifth-level wolf beast would once again become the king of this group of wolves!

In a small forest almost twenty-five kilometers away from here, Qin Xiaoyan was lying on her bed and couldn't sleep peacefully.

It's twelve o'clock at night, why is she insomnia? It's been a long time since I've had insomnia, and I sleep in bed on weekdays!

It's all that damn Qin An! It made her upset, and sure enough, it was right to leave Qin An! She obviously didn't feel any love for him anymore, so why did she care about him? What a contradiction!

A wolf roar suddenly sounded, startling Qin Xiaoyan.

It seems that the sound is coming from a long distance, and it is estimated that it is twenty or thirty kilometers, right? It's supposed to be a big guy!

This dangerous beast area is indeed a dangerous place, so I'll take the students into it tomorrow! I have the ability of the heart of a desolate beast, so I should be able to ensure the safety of those who travel with me, right?

Oh, my God! She would think of so many useless and boring things, could it be that this was all because Qin An appeared again and disappeared in front of her eyes. Really don't like the feeling.

Qin Xiaoyan focused her attention and didn't intend to think about these things.

After concentrating, Super Hearing turned on at the same time, and Qin Xiaoyan could hear the conversations of everyone in the camp!

Eavesdropping on others unscrupulously is actually a very wonderful thing, Qin Xiaoyan's heart finally calmed down, and she planned to listen to other people's privacy and slowly fall asleep.
