Shu Yunpeng doesn't know many people here, and even fewer people he regularly interacts with. Therefore, in addition to Huang Lang, he also invited Claire and Zhang Jingyi to accompany him, plus a few of them.

The dinner was very good, Shu Yunpeng personally instructed Qin Huaiyu and them to make it, and everyone ate very happily. Due to the lack of ingredients, the people here have long since stopped paying attention to cooking skills. Shu Yunpeng is not from here, although he is not a master of cooking in his world, but today he showed his hand.

"That's great!" After eating, as soon as she returned to the living room and sat down, Zhang Jingyi was full of praise: "I haven't eaten such a delicious meal for a long time!" ”

All agreed.

"Are you all so particular about food there?" Yi Ru asked curiously.

"Is this exquisite? If you see the full banquet of the Manchu and Han people, you will know what it means to be exquisite! Shu Yunpeng said, in fact, he had never seen it himself: "It's a pity, there are too few things to eat here!" ”

Starting from the trivial matter of ingredient comparison, the topic naturally turned to what Shu Yunpeng wanted to say. He started with the ingredients, talked about the basic extinction of wild animals, the complete extinction of domestic livestock, and finally talked about the plight of human reproduction itself......

"What I have been unable to figure out is, is all this irreversible?" He did work hard: "The era I live in coincides with the prevalence of the theory of the uselessness of reading, so I don't study very well. In my world, I'm semi-literate. Isn't it strange that there are so many people here who don't know anything even I know? ”

Although Shu Yunpeng claims to be semi-literate, he is still a person who is more willing to teach himself in his world. His eloquence is somewhat famous among acquaintances, and he is called a "doctor of sociology". His words, not only Claire, Zhang Jingyi and others were shocked when they heard it, but even Huang Lang, who was rich in five cars, was also shocked.

He knows that when a person is born and raised in this world, he will think that this world is what it is, but it is not. This is the so-called "I don't see the true face of Lushan, only because I am in this mountain".

Shu Yunpeng is an outsider, and he found that the problems that many people here ignore are normal. But it is undeniable that this is also a matter of using their brains. Shu Yunpeng is a person who uses his brain and thinks seriously.

"Mr. Shu really lives up to his reputation!" After Shu Yunpeng finished speaking, Huang Lang pondered for a long time before saying: "In the vast universe, the earth is like a leaf on the vast sea, and human beings are a group of ants on this leaf. ”

When he said this, he looked at everyone present, and continued in a heavy tone: "This group of ants who do not know whether they are alive or dead, claiming to be the "spirit of all things", but they are constantly ruining this leaf under their feet, and it is finally full of holes! ”

"The point is, this group of arrogant ants doesn't seem to have stopped," Shu Yunpeng said: "To be honest, Professor Huang Lang, I don't know how many members of your committee have seriously and carefully considered how to save the earth and save mankind?" ”

"You're right, people nowadays have become very impetuous, and they always have headaches and pain in the face of difficulties...... The pressure of survival is too great, and people are confused! ”

Huang Lang slowly, starting from the two global wars, has been talking until now. He told Shu Yunpeng that many things people didn't expect at first. When the consequences of war began to become apparent, few people around the world realized that the danger was coming. However, their voices are too weak, and some are even dismissed as alarmist.

It is generally known that radiation kills people. The Chernobyl nuclear accident in the 80s of the 20 th century caused the deaths of hundreds of thousands of Soviet troops and civilians, and more than one million people suffered from various degrees of illness due to the effects of nuclear radiation, most of them died of cancer, and the rate of neonatal malformations increased greatly. It's all in these textbooks. Even after 10,000 years, this is still a topic that is often brought up.

"However, there is a potential danger that humanity knows nothing about!" Huang Lang said: "When mankind realizes this danger, the crisis has already erupted! ”

Huang Lang told Shu Yunpeng that after the two global wars, there were several more local wars.

This was followed by several great famines and great global riots. The Great Famine and the Great Riot are no less harmful to mankind than all-out war.

When people feel exhausted, they find that there are less than 200 million humans left in the world. Moreover, many of the 200 million people are still old, weak, sick and disabled. With such a population base, the state inevitably disintegrated.

What's worse is that people in a state of no **, due to the lack of various resources, including food, continue to bully. Some knowledgeable people began to unite and call on people to abandon antagonism, give up prejudice, and stop hating and killing each other, and it was under such circumstances that the Earth Alliance was founded.

It should be said that in the early years of the Alliance's existence, its work was still fruitful. Because of the sharp decline in the population, the alliance called for the full intermarriage of all races, and the yellows, whites, and blacks were integrated in that era.

After learning from the pain, all the people began to work hard, and although the vegetation of the earth was basically destroyed and the land was seriously desertified, the situation still improved through the efforts of everyone.

However, unexpectedly, the potential danger quietly appeared during that time.

In the beginning, it was discovered that as long as it was aborted, nine times out of ten it was a male fetus. After birth, boys are also particularly susceptible to early death. Even when they do reach adulthood, most men appear to be particularly weak and have a short lifespan. After this state of affairs continued for a while, people suddenly realized, why are there so few men?

Terror gripped everyone's minds, almost causing a global panic: Is this God punishing humanity?

The alliance attaches great importance to this. They concentrated all the experts and technicians who worked day and night and finally found that the male reproductive system of the human being was devastating due to the action of radiation, which is the so-called Y-system collapse crisis!

All experts, scholars, and scientific and technological workers are committed to developing and researching targeted drugs and setting up effective prevention facilities. But it was already too late, and this punishment of nature seemed irreversible. In the end, protecting the few remaining men from harm became the first priority, and it was at this time that the construction of Central City began.

The idea was to create multiple cities like Central City. But unfortunately, the Jones people are coming! They also have a base on the moon!

War inevitably broke out...... After nearly a hundred years of tug-of-war, the earthlings, who had made great sacrifices, finally destroyed the Jones base on the moon, and destroyed the beautiful Moon Palace with half of it...... Moreover, the earth's ozone layer, which was already overwhelmed, has also become a devastation because of this war!

This increases the source of radiation by an order of magnitude----- from the sun's harmful radiation!

And the earthlings, the war has depleted the resources of a city with a protected system like Central City! The inability to build new cities meant that at least two-thirds of the population could not live in the central city, and this is how agglomerations appeared.

After Huang Lang finished speaking, there was silence in the room.

What else can be said? The whole process seems to be predestined. But what role did humanity itself play in this, pushing itself irretrievably into the abyss of extinction?

"If the collapse of the Y system cannot be reversed, will humanity disappear soon?" After a long silence, Claire spoke first: "Really, Professor?" ”

Huang Lang sighed heavily: "Yes." There are still men in our generation, and although most of them are no longer normal, they can barely sustain the continuation of humanity. However, the point is that there are almost zero baby boys born now! When this generation passes, the world will be completely devoid of men, and it will only last for a few generations if all the reserves of the human resource pool are exhausted...... Then, once that time comes, women will not have a chance to get pregnant and have children, and even girls will not be born in this world! ”

"So, isn't cloning going to work?"

"What a drop in the bucket!"
