This sentence made the strong people present silent.

No matter how proud they are, they all know that a very simple common sense human being who claims to be the "spirit of all things" and "ruler of the earth" is actually far less powerful than self-proclaimed and can completely rule the entire earth.

So far, more than 90% of humans still live in 1% of the surface area. They would rather crowd these areas with good weather and suitable environments like honeycombs than, and dare not, to advance towards the vast and vast mountains and rivers.

Not to mention, most plateaus, deep valleys, deserts, rainforests, seas, and underground are not suitable for human survival at all.

Rather than saying that humans are the rulers of the earth, it is better to say that humans are prisoners of the earth, trapped in a small cage by their own weakness.

"Eliminate all intelligent life underground", a gentle and clever sentence, but in practice, what should I do?

If humans had a way to completely eliminate snakes, insects, rats and ants, they would have done it eight hundred years ago, and they would have to wait until today?

Even ordinary rats cannot be completely extinct, so what confidence do you have? What are you talking about completely eliminating the rat race civilization?

"I admit that the rise of underground intelligent life is indeed a great challenge to human civilization on the ground. It is an incalculable difficulty to completely curb the threat from underground. This is an unprecedented threat. It is simply an enemy from another dimension, which is different from the threats we once imagined from the cultivation world and the illusion and demon world."

Guan Shanzhong said with a serious expression, "However, because the enemy is difficult to eliminate, you might as well not eliminate it, or even think about how to eliminate it. What is the difference between such a method of stealing the bell from the way of burying your head in the sand and pretending that it does not exist?

"Chu Ge, I'm not saying that the rat civilization will definitely become the enemy of human civilization. What I want to say is that if we want to eliminate the threat from the underground, now is the best time. The further we go, the threat index and the difficulty of elimination will increase in geometric levels. The reason is very simple, because the other party's reproductive power is too strong.

"With sufficient resources, ordinary mice can develop and mature in a few months and can produce several litters of cubs a year. These cubs can join the breeding army in less than a few months. In this way, they become two, two, four, and eight. The entire group of rats expands a hundred times in a year, which is common.

"Suppose there are a million mice under the ground in Lingshan City now. According to the calculations of zoologists and environmentalists, this number is still far underestimated. Then, if it expands by one hundred times a year, it will be a full 100 million, two years, and three years. Can you imagine the number of rat civilizations in three years?

"The opportunity is fleeting. If we hesitate for a while, aren't you afraid that the entire underground of Lingshan City will become a rat world after a year or two?

"At that time, no matter these... you can understand the heroic and fearless rat race that you can understand whether it is good intentions or malice, they have no choice but to rush to the ground and use their fangs and claws to seize new living space for their descendants!"

Before Chu Ge was completely awake, the information he spoke intermittently had already been highly valued by his superiors.

Countless sociologists, zoologists and psychologists have discussed together the possibility of mice forming civilization.

Assuming that the "rat civilization" really exists, the most terrifying advantage is undoubtedly its unparalleled reproductive ability.

The overwhelming number and wisdom comparable to human beings are definitely the most terrifying threat to human civilization.

All of them are adults, and they are already past the age to judge things by "goodness" and "evil".

It doesn't matter whether the rat race is "good" or "evil".

What is important is that their rapidly expanding number and the scarce resources underground will inevitably inspire an irreconcilable contradiction, which drives them to point the battle flag to the ground in the end. Even if the "gods" they once believed in, they cannot stop their desire for survival.

Therefore, many strong men nodded, agreeing with Guan Shanzhong's judgment and worries.

They also stabbed their sharp eyes at Chu Ge, wanting to know whether Chu Ge was confused for a moment, whether the woman's kindness broke out, or whether he thought about it carefully.

Chu Ge thought about it for a long time.

What Guan Shanzhong is worried about is also what he is worried about.

His eyes were not blind, so he could naturally see how terrible the rat tide was, perhaps even more terrifying than the insect tide of the same level.

However, after going deep into the Kingdom of Tooth and learning about the social form of the rat civilization, Chu Ge had a deeper understanding of this issue.

"Major Guan and everyone's concerns are naturally very reasonable, but on the other hand, can we reach such a consensus?"

Chu Ge said with a bright look, "The biggest threat to the rat civilization is its number. Only by forming a overwhelming tide of rats can it be scary enough. If it is just one or two little mice that awaken their wisdom and cultivate into spirit, there is nothing scary at all?"

Everyone looked at each other, Guan Shanzhong nodded on behalf of everyone, "Of course, we have discovered many monsters that are lonely. Even the prehistoric beasts that are overturning the rivers and seas are not surrendered in front of our missile destroyers and aircraft carrier formations, or are beaten to run away from the head and run away, and have to escape into the deep sea to lick your wounds?

President Yu and Director Mu also said that the authorities can open the door to the monsters that are single. Whether it is the extraordinary association or the special agency, including some special forces within the military, there are examples of raising monsters and allowing them to serve humans. They do not have to be killed.

Chu Ge said again: "Then, if it weren't one or two rats, but ten thousand, one hundred thousand or three hundred thousand or five hundred thousand rats with wisdom, do you think it would definitely pose a serious threat to human civilization?"

"this……"

Everyone frowned.

"It seems that everyone does not think that 300,000,000 wise mice will definitely shake our great civilization. Therefore, the key issue is the number. If there is a way to limit the terrifying reproduction ability of the rat race, we may not necessarily choose the most extreme route." Chu Ge said.

"The words are right, but how can we limit the number of rat tribes? Can we hide deep underground and spend nightlife secretly? Can we still use flashlights to shine them in and distribute safety supplies to others?" Guan Shanzhong said a cold joke expressionlessly.

"This is the key to what I want to say. I found that everyone is trapped in a misunderstanding of thinking. Everyone thinks that since ordinary mice can be born, a rat who awakens wisdom will definitely inherit the same level of reproductive ability and willingness."

Chu Ge said, "But, based on my observation, this speculation may not be valid."

Everyone was slightly stunned, and a "buzzing" discussion sounded in the ward.

President Yu's eyes lit up and he leaned over and said anxiously: "Chu Ge, please explain clearly, what exactly does it mean!"

"You will know if you think about it carefully. Take human civilization as an example. Our fertility rate has never been static, but has been constantly changing with the continuous development of the economy and society."

Chu Ge talked freely, "Generally speaking, the poorer the more you are, the more chaotic the more you are, the lower your level of civilization, the worse your medical conditions are, the more you are displaced and war-torn, the more you want to live.

"The richer, more stable, better medical conditions, and advanced civilization, people have higher level pursuits that transcend material things, and the lower the fertility rate.

"In the global war-torn era two or three hundred years ago, it was so common for a woman to have three or five children, five or six children during her childbearing age. There are also many people who have given birth to more than ten children and finally feed two or three children. Therefore, when the medical conditions are slightly better, countries around the world have experienced the era of "population explosion". It is normal for the population to double or quadruple in just a few decades.

"But, have you ever seen a 'population explosion' that lasts for decades, hundreds of years, and continues to explode? Often when the population and economic development reach certain limits, an invisible hand will twist the switch, and the fertility rate will naturally become lower and lower.

"Today, it is the same, like Lingshan City, which is located in the core area of ​​the alliance, known as a fertile land, and is not particularly scarce in places. People are not very enthusiastic about giving birth. Often one or two or two children are the limit. However, in the wilderness of the border of the alliance, those lawless and turbulent places, people will make every effort to give birth. Regardless of whether they can raise or not, they must give birth to ten or eight before they can stop.

"There are naturally profound political, economic, social and even moral and ethical factors here. I won't talk nonsense, I just explain such a fact.

"If someone takes the fertility rate of the alliance border and the wild land, it is naturally ridiculous to think that young citizens in Lingshan City are wondering why they are unwilling to have more children and more blessings.
