Shu Han and Su Yu are not stupid people, and after Tan Yongming said it, he suddenly figured out the joints, "Darwin, the fittest survive, and the unfit are eliminated." This is the meaning of Tan Yongming's words, because oxygen enrichment will bring about the crazy growth of bacteria in the human body, resulting in high temperatures, causing huge damage to the internal organs and organs of the human body, and the vast majority of people will die in it.

Only a small number of people will survive, who will? Naturally, people with a drop in body temperature can adapt to the high temperature caused by the growth of germs in the body through the drop in body temperature, so as to produce antibodies in the process, and its low temperature is inevitable, because this can effectively inhibit the growth of bacteria in the body, so as to achieve a balance in the oxygen supply in the body, so people with low body temperature can live to the end.

After figuring it out, Shu Han and Su Yu had a feeling of sudden enlightenment, and Shu Han muttered: "This is really possible, but what could cause the oxygen content to rise suddenly?" Now that the desertification is so serious, the greenhouse effect is melting the glaciers in the north and south poles, and the carbon dioxide content is getting higher and higher. ”

"I'm afraid it can't, I think, Tan Yongming is right, the reason why people's body temperature will become lower in later generations is likely to be related to oxygen content, but the extinction of human beings today is not necessarily related to oxygen, it may be that human beings died out for what reason, resulting in a general increase in the number of green plants on the earth, which leads to an increase in oxygen content, which is the reason for the second wave of human extermination, but it will definitely not be the first wave."

Su Yu reacted at this time, and these words were like a basin of cold water, poured on Shu Han's body, and he said eagerly: "Then this doesn't mean that he didn't say anything, we still don't know what will happen in the future." ”

"This at least lets us know some possibilities about the future, Shu Han, this is already the most reliable guess, you cheer up, we haven't got an answer for so long, we won't be bad for a while." Su Yu couldn't help but persuade, Shu Han, shook his fist, and then the unwillingness in his heart was unbearable, and he said to Tan Yongming: "I'm sorry, I was a little impulsive just now." ”

"It's okay, I'm just thinking about it." Tan Yongming said a little embarrassed, seeing that the atmosphere was a little embarrassing, Su Yu opened his mouth to help, diverted the topic, and said, "Brother Ming, how did you think of this?" It really didn't occur to me that the death of humanity could be due to oxygen. ”

Because the three of them shared secrets together, Su Yu's title for Tan Yongming also changed and became more intimate, Tan Yongming was a little uncomfortable, but he also followed Su Yu and said: "Because human beings are not all extinct, if there is a super huge flash flood, volcanic eruption, or a super-large-scale earthquake movement, then it is probably difficult for human beings to exist in this environment."

You can look at several mass extinctions between the Cenozoic and Paleozoic eras, whether it is the Ordovician mass extinction or the Permian mass extinction, which is caused by a huge crisis caused by volcanic eruptions, more than 90% of the life on the earth will die, of which chordates are almost all extinct, and humans are among them.

For those of us who need too much material in a day, we simply can't get enough nutrition in a short period of time, and the entire human civilization will be in violent turmoil, and it will not be possible to exist for hundreds of years and still be able to see those buildings.

As for the second evidence, it is because according to Shu Han, the world he went to is only about 300 years away from now, if it is really a spontaneous mass extinction event on the earth, even if it is the most Ordovician mass extinction caused by the rise in temperature, it will take hundreds of thousands of years, which is already the shortest mass extinction time, and the others are either millions of years, or tens of millions of years, if it is really an independent mass extinction of the earth, then it is probably difficult to have reservations.

After all, with the current ability of human beings, some small-scale disasters cannot cause complete turmoil in human society, and with the use of science and technology, human beings can completely avoid it in advance, and when the disaster passes, everything will be as usual, so it is impossible to be a small disaster.

After these are excluded, there are not many disasters left, nothing more than a sudden increase in oxygen levels, or a sudden change in the earth's environment caused by the greenhouse effect, or an attack on the earth by an alien civilization, and a huge war within mankind itself, thereby changing the earth's environment.

As a result of the rapid deterioration of the earth's environment, I can't predict the next few guesses, so I can only make one or two guesses about the oxygen content, so I thought of this possibility and said it casually. Tan Yongming said in a very professional tone.

Su Yu on the side patted Tan Yongming's shoulder and said, "You still call it a casual remark, our brothers have never thought about such a detailed question, Tan Yongming, you are a friend, we really have to make a deal." ”

Shu Han on the side looked at Tan Yongming and said, "Then what do you think is possible to change the oxygen content of the earth?" ”

"There are many reasons for this, but it should not be the so-called nuclear war, this can be ruled out, Su Yu also said that many buildings in Hai'an City still exist in later generations, that is more than 300 years, if a nuclear war really breaks out, a megalophone like Hai'an must be the target of attack, and it is impossible to have landmark buildings remain.

So I guess that in addition to the possibility of aliens that cannot be judged by reasoning, it is nothing more than greenhouse gases that cause the earth's temperature to rise, plants to begin to multiply, and at the same time, the rise in climate temperature leads to the increase in the temperature of seawater, and according to many scientific journals, there is a large amount of combustible ice in the underground seawater, the scientific name of combustible ice is natural gas hydrate, and the chemical formula is CH?· nH? O, because when mined it is very much like ice, it can be ignited with fire, so it is called combustible ice. ”

"These combustible ice are buried hundreds of meters below the seabed, and the perennial temperature is about 10 degrees Celsius to 17 degrees Celsius, it is said that our reserves in the South China Sea are very rich, and it is one of the primary choices for clean energy in the future, but the melting point of this combustible ice is only 20 degrees Celsius, that is, if the environment continues to be polluted, carbon dioxide emissions are too large, and the earth's ozone layer continues to be destroyed, so that sunlight can pass more through the ozone layer on the earth's surface, thereby causing the earth's temperature to rise, Combined with the increase in the temperature of the seawater, which causes the combustible ice beneath the seawater to spontaneously combust, it poses a great danger.

Combustible ice will produce a lot of water and carbon dioxide after it burns, which will continue to increase the temperature on the earth, and a lot of water will make the sea level rise, and eventually a large amount of land will be submerged, which is also the same as Su Yuge said before, there are many differences between the surface distance in a hundred years, so this is very possible.

The rapid rise of carbon dioxide will cause a short-term lack of oxygen for human beings, while plants will get this carbon dioxide, as well as more sunlight, so as to grow rapidly, and it is entirely possible to cause the final outcome of the world experienced by Shu Hange in three hundred years. ”

Tan Yongming's reasoning made both Shu Han and Su Yu fall silent, and finally Su Yu spoke: "Brother Ming, I regret it a little now, I told you about this matter later." Tan Yongming smiled and said: "It's nothing, my speculations are just my own thoughts, the changes in the world are always based on our thoughts, who knows what the real reason for the destruction of the earth is?"

Besides, even if what I said is right, there is nothing we can do about it, global warming, that is not something that the three of us can solve, is it possible that we can still get all the leaders of the world to declare that they will no longer industrialize, and then everyone will slash and burn? Isn't that worse than the apocalyptic situation? ”

When Tan Yongming said this, the eagerness in Shu Han and Su Yu's hearts was instantly extinguished, and after drinking the wine in the cup, Shu Han sighed and said, "So I really don't know, why does this God want me to see the scene after the apocalypse?" I always thought that it was for me to save humanity and human civilization, but now it seems that it is a joke. ”

"Shu Han, don't be too discouraged, life and death are fateful, wealth is in the sky, I can open this point better than you think, and Tan Yongming's detection may not be accurate, after all, he explained everything in these words, but what about those abilities? As you said, in your world, there is a group of people who are different from ordinary people and have special abilities, so what are they?

There are still many questions that cannot be solved, maybe the answer is not so, but there is another mystery? Su Yu comforted, and Tan Yongming on the side also said: "That's right, and even if the earth is really destroyed in nine months, your apocalyptic experience will be very useful for our survival in the future, after all, no one else has seen this scene, but you have really experienced it, maybe God gave you this ability, not to save human civilization, but to let you restore this world to its original state?" ”

"Brother Ming is right, besides, the power of heaven is unpredictable, what God wants to do, how can we know, or just a coincidence, Shu Han, according to me, the bridge to the bow of the boat is naturally straight, let's take a step by step, after many people know the future scene, most of them eat and wait to die, and some are crazy, maybe they are stupid, we have been unremittingly tracking clues, and we are still singing to make money and raising funds, compared to others, it is already very hard, don't be presumptuous."

"I know, it's almost time, let's go back and rest." Shu Han said with a wry smile, he has put a lot of effort into this, and now he wants him to accept the reality, accept the reality that the earth may be destroyed in nine months, it is really difficult for him to do it, Su Yu and Tan Yongming are not like this, Su Yu invited the two to sleep in his house that night, Tan Yongming insisted on refusing, he must go home.

"I miss my mom a little bit, and I want to go back and see her," he said. There was a little bloodshot in his eyes, mixed with tears, Su Yu couldn't bear this fourteen-year-old child, so he patted him on the shoulder, and then hugged the little brother, and when the two separated, Su Yu's chest was wet.

"Cut, this kid, I miss my parents a little bit." The smile on Su Yu's face at this time was even more ugly than crying, Shu Han looked at him and said: "Sometimes I really envy those who don't know the truth of the matter, how happy they are, how happy they are, how happy they are, how happy they are, obviously at the age of seventeen or eighteen, it is the time of presumptuous youth, but like an old man, he cares about the changes in the world and the future of mankind."

Sometimes when I think about it, I think it's funny. Saying that, Shu Han really laughed out loud, and Su Yu on the side also laughed with him, and said: "That's right, I'm about to become a little old man, you say, this kind of thing, how can it be put on your hands, if you change anyone, I don't bother to care, Shu Han, if you are still alive in nine months, you have to be my grandson." ”

"When you're a grandson? Call Grandpa to listen first. Shu Han naturally will not be polite, the two of them played for a while and fell asleep directly in the living room, and when they woke up the next day, their heads were dizzy, thinking that there were classes today, the two of them were busy and were about to leave, and suddenly remembered that the three of them had received an invitation to the summer camp of Beijing University, and they could prepare well at home these days, without going to school to report, and strive to get a good score back.

Only then did he quickly put the bag down, and after waiting for a few minutes, the sound of ringing the doorbell sounded outside the door, Shu Han saw Su Yu lying on the sofa and fell asleep again, so he walked over and opened the door by himself, "Tan Yongming, come so early." Shu Han said, the person who came was Tan Yongming, it was not yet seven o'clock in the morning, and Tan Yongming was too early.

"Well, I suddenly thought of a possibility, and I wanted to come and talk to you." Tan Yongming said.

"Come in and say." Shu Han looked at the residences on both sides, and then stretched out his hand to let Tan Yongming in, Tan Yongming said as soon as he came in: "Yesterday you said that people in the end of the world have all kinds of abilities, I suddenly thought that in many documents, it is said that human beings in the prehistoric civilization era have strange abilities, for example, in Plato's book, there is a country called Atlantis, it is said that people there can live to be four or five hundred years old, and will not grow old for life, and in China, there is also a legend that King Wen of Zhou entered the Western Queen Mother State and was blessed by the godsAre these so-called gods and city-states the so-called supernatural people? ”

"Aren't these all legends?" Shu Han frowned and said, he has also heard these stories, whether it is China or a foreign country, in every nation, there will be some gods and some heroes, they have skills that human beings have not mastered, but these are often the results of exaggeration in the process of the singer's transmission, as for those gods, most of them are ignorant of the ancients, do not understand the changes of the natural climate, so they are worshiped as gods after anthropomorphism, Shu Han never thinks that these things can be true.

When human civilization dies
