Following Mr. Chen, after climbing the city wall, Mr. Chen asked about the city defense situation, while Shen Rui used his eyesight to look around.

On the far horizon, many vague alien beasts appeared faintly, followed by many ordinary beasts.

Wild wolves, wild sheep, wild dogs, wild boars, wild rats... these are the most common sources of abnormality, followed by crows constantly circling in the sky, occasionally driven away by sparrows.

The appearance of crows is often the beginning of a war.

When wild beasts develop intelligence, the ecological balance loses its regulatory role.

Just like when man first grasped the power to conquer nature, he began to destroy nature unscrupulously, multiplying, cutting down, overharvesting, and burning, turning large green areas into deserts and green water into black water. In the end, he had to bow his head to nature. .

I think I have conquered nature, but in fact nature doesn't care at all.

Human beings have deeply understood this. The earth does not need to be saved by humans. All humans need to save is themselves.

But these alien beasts, who have just mastered power and wisdom, don't understand this yet. They are still like human beings in their early childhood, wanting to conquer the earth by their own strength.

So they desperately expand their populations, use their wisdom, and avoid the regulating mechanism of ecological balance.

"Approximately how many have been observed so far?" Shen Rui asked a mutated sparrow that landed.

"There are probably hundreds of thousands of them around now, and there are many wild beasts coming within a few hundred kilometers." The sparrow returned.

Shen Rui nodded and continued to look into the distance.

Hundreds of thousands of pigs are not much for the land of a county. In peacetime, there are hundreds of thousands of pigs in stock, let alone other animals.

But that is based on the productivity of modern industry and agriculture. The natural ecological environment in the wild cannot support such a large community, not to mention that many of them are exotic animals.

They swarm here, and the herbivores will soon eat up all the food in the wild, including a lot of bushes and grass. The carnivores prey on the herbivores, kill each other, and finally attack the human castle.

This is the new ecological balance currently being formed.

As Shen Rui thought about it, he looked from a distance and saw that there was indeed a fierce conflict between the strange beasts.

For wild wolves, the wild sheep that swarm over are simply food delivered to their doorsteps. Instead of chewing on human bones, it is better to eat these guys first.

Soon the wild sheep were hunted one by one, but the mutated goats seemed indifferent and only guarded some lambs. They were not bothered by the hunting of ordinary wild sheep at all.

As for what those wise wolves did, Shen Rui, who was looking at him, was slightly shocked, but felt that it was reasonable.

He saw a red wolf, raised a fire on the spot, threw the wild sheep into it, smoked it dry and roasted it.

He saw another white wolf, which actually summoned ice and snow and froze the dead wild sheep on the spot.

After these things were done, there were many ordinary gray wolves, under the shouts of the different wolves, carrying the food on their backs and transporting it to the rear. They seemed to be making military rations and food for the winter.

Among them, there are also wild dogs and rats that come to take a share of the pie. Of course, those who are eligible are only those who are alienated.

No wonder the abnormal tides in the north are largest in winter and much smaller in summer. It is precisely because winter is cold and it is easier to preserve food. At this time, they can kill each other and not waste precious nutrients.

The situation in the south is different.

Shen Rui frowned, and a huge pressure suddenly arose. These alien beasts, they attack the human castle, not just to reduce the pressure of survival, but more like artificial training of troops.

Eliminate the ordinary beasts, leaving the alien beasts, and then pass through the human castle to eliminate the garbage among the alien beasts, leaving only the elite.

These elites will breed ordinary beasts in the next year, and if they continue like this, I am afraid that in another thirty to fifty years, these castles will not be able to resist them!

They have no humanity and choose the cruelest and most bottomless death competition, but they have to admit that this road goes very fast.

"It seems that you understand a lot of things." Mr. Chen on the side said with concern.

"Yes, Mr. Chen."

"Call me Uncle Chen. I'm actually a few years older than your father. Don't call me that again." Mr. Chen said kindly.

"Okay, Uncle Chen," Shen Rui changed his title naturally, "These strange beasts seem to be using us to eliminate the fittest."

"Yes, you should have studied history and seen the history of the rise of the Manchu and Qing Dynasties. In fact, the Manchu and Qing Dynasties are also full of internal contradictions, but they set up the Ming Dynasty as a target to unite as one and use the Ming Dynasty to hone their army and learn from it. Nutrition and strengthening yourself. The same goes for these strange beasts." Mr. Chen taught seriously.

"Well, it's very similar. Sure enough, history repeats itself." Shen Rui nodded, fully agreeing with this point.

"However, we humans are not the corrupt Ming Dynasty. Although we still have many problems, there are still many people who are greedy for life and afraid of death, and many people are scheming, but there are more solutions. After all, we have entered modern civilization and have long known how to use science. Methods to solve problems!" Mr. Chen encouraged, "And they are far from learning science."

"Well, I've always believed that."

The soldiers standing on the city wall all showed excited expressions, and their morale improved for a while.

But suddenly someone asked:

"What if these strange beasts also learn our science?"

When everyone heard this, they immediately stared at him angrily. The man was wearing a gray team uniform and had an ordinary appearance. Seeing everyone angry at this moment, they were a little trembling.

"Haha, don't blame him, many people think so," Mr. Chen pressed his hands to signal everyone to be quiet, "But, I want to say, if the monsters learn science, they will no longer be scary. Human brains and hands can It is the most suitable for developing science.”

"When they put their energy into learning our science and copying us, they are doomed to fail. But we can use this time to thoroughly study the emerging subject of special particles. That's when a complete counterattack begins."

"I see, that's right. Are we still afraid of comparing science with mice? Unless they become humans." Someone cheered.

Hearing this, Shen Rui didn't smile. He thought of the mountain tiger, that strange tiger that could transform into a human.

How did the other party modify the structure of his body through special particles? Transformed from a tiger into a human?

Could it be that the opponent is not the third level on the surface at all, but a convert after the ninth level!

His expression changed, and he remembered a book he had read, which mentioned his conjecture about the ninth level.

That conjecture means that at the ninth level, physical practitioners can already directly control cells throughout the body through special particles, and then control genes.

The genetic difference between tigers and humans is actually far less significant than their appearance. You must know that the genetic similarities between pigs and humans are extremely high.

Mr. Chen seemed to notice Shen Rui's worry and came over and patted him on the shoulder, signaling him not to speak.

Shen Rui is not a real high school student, so of course he will not say anything that damages morale like the guy just now.

However, it can be seen that in the hearts of the people at the bottom, weirdness is really scary.

Humans have so many advanced weapons, but they can't exterminate them. Instead, they are compressed into the castle and defended.

And all of this is done by special particles that are invisible to the naked eye and can only be sensed by the mind.

"Look, that group of wild wolves and a group of newly arrived wild boars are killing each other!" someone shouted excitedly.

Shen Rui looked up and saw a group of wild boars, led by a large wild boar, attacking the wolf that was processing the food on the assembly line!

Dust was flying, screams were loud, blood and flesh were flying, and it was a mess.

No wonder this player is so excited. Probably in the eyes of the opponent, this kind of cannibalism can greatly reduce the defensive pressure in the future.
