Everyone gasped, feeling that these little demons in their hands were even more terrifying.

They've eaten people?

Lao Xu continued: "Judging from all kinds of signs, there should be more than a few humans here who have eaten rats. You've also discovered that they have a strategy. It was from above and down, and then the army of the underground swept over again. From this, it can be seen that they have a lot of experience in attacking large creatures, and this large creature is very likely to be us. ”

Everyone shuddered, never expecting that there would really be a thing of rats eating people.

The soldier asked again, "Are these rats that eat people poisonous?"

When asked these professional questions, Lao Xu was also very happy to explain to everyone, and said while working:

"Actually, from a scientific point of view, these rats should be cleaner than the rats in the outside city. Because this is the depths of the earth, far away from human society. There are very few bacteria that can thrive in such deep ground. They have not crawled through stinking ditches and garbage heaps, so in theory, there should be fewer viruses than rats in the outside world. ”

"However, I don't know what the actual situation is, because there is one problem that I haven't figured out yet. ”

The crowd was already fully interested, and asked, "What's the problem?"

Including Li Xun, they all pricked up their ears and listened with interest.

Li Xun is very interested in these very professional knowledge.

Captain Zhang, who was indifferent to anything, and the two indifferent young men also stopped what they were doing, looking at Lao Xu with blank eyes, waiting for him to tell him about the problems.

Lao Xu earned everyone's appetite, and was very satisfied with being looked at with such adoration, and said with a smile: "Work hard, work, I'll tell you while working." ”

Everyone hurriedly lowered their heads and worked, but a pair of eyes were staring at Lao Xu tightly.

Lao Xu just wanted to speak, but Lao Niu interrupted: "What are you doing with your appetite, it seems that only you understand." ”

Lao Xu just wanted to refute, but Lao Niu said in a loud voice: "This question is not difficult to understand, what bothers us is actually the problem of food sources. You know, this is hundreds of meters underground, and judging from the available information, the rats in this rat hole seem to be imprisoned by something and can't get out of this cave. So the question is, what is the food of all things in this cave? It can't be, hundreds of years have evolved the ability to skip food, right?"

Lao Xu glared at him and answered:

"Lao Niu is right, this is a very important issue, I think this can be explained in terms of water source, because the water hole leads here, and there must be water underground. But the food source is very troublesome. If we know what their daily food is, we may be able to know how much bacteria they have compared to the outside world. ”

The old cow laughed.

Everyone didn't know why, they didn't know why he was laughing.

Expert Xu glanced at him and muttered, "Sick." ”

But the old cow said, "Old Xu, are you stupid? Isn't it easy to find out what their usual food sources are? ”

Lao Xu was stunned, his face was slightly red, he was a little ashamed, and secretly scolded himself for ignoring this stubble, it was really embarrassing.

As he spoke, the old cow broke open the belly of a mouse with a dagger.

After opening his stomach, he was startled, and hurriedly threw away the dead mouse in his hand with an exclamation: "Damn!"

Everyone was stunned and looked at Lao Niu suspiciously, but they didn't know why he reacted so much.

Lao Xu wondered, "What are you doing?"

The old cow gasped a little frightened, and said with some disgust: "See for yourself." ”

Lao Xu picked up the disembowelment mouse and took a look, his hands shook in fright, and he hurriedly threw the dead mouse out, his face was cloudy.

The old cow asked, "See." ”

Expert Xu gasped: "It shouldn't be, it's not scientific, it's impossible." ”

Li Xun asked curiously, "What's impossible? What's wrong?" What are they eating?"

Expert Xu said in a deep voice: "Eat yourself!"

"What?"

The crowd was in an uproar.

Li Xun hurriedly walked up to the dead mouse and took a look, his eyes widened, but he saw that there was still half of the undigested mouse tail in the stomach of the mouse.

Exclaimed: "Cannibalism?"

Lao Niu's face was very solemn at this time, and he said, "This is something that has never been heard of in the entire biological world. Because rats are very intelligent and are not the kind of imbecile creatures that only know how to eat instinctually. Intelligent animals will cooperate and know how to work as a team. And with teamwork, it is impossible to kill each other, let alone use the same kind as a source of food. ”

Li Xun said loudly: "No, this is a Gu rat!"

Everyone looked at Li Xun suspiciously, and asked what a Gu rat was.

Li Xun said in a deep voice: "This is the favorite way for the Gu cultivators in Miaojiang, put the poisonous insects together, let them kill each other, devour each other, and the last strong one left behind is called Gu." This Gu rat is the same as a Gu rat, someone put them in this cave and raised them in the way of raising Gu. ”

"These rats can't get out, have a limited food source, and naturally devour their own kind. If I'm not mistaken, after hundreds of years of evolution, a law may have been born in their internal group. My guess is that every cycle, there will be a corresponding number of weak people in the group, and then the other rats will kill these weak people and eat them. ”

"This is an extremely cruel law of the jungle, the whole group of rats is limited by food, maybe not too much, but the individual strength, will become stronger and stronger.

Each rat will become more and more ferocious and brutal, in order to get more food, and so that he will not become a weak person to be eaten.

This is how to raise Gu rats, I don't know if there are Gu rats in other parts of the world, but I guess this should be Gu rats. ”

Everyone shuddered when they heard this, and they didn't expect that there was such a big secret hidden behind this little mouse.

The intentions are sinister.

It's horrible, it's scary to think about.

No wonder the rats in this rat hole have such a powerful attack, such a brutal behavior, and such a ferocious manner, this is a group of rats raised by people by means of raising Gu.

God knows, in this group of rats, has evolved a more powerful king.
