"Before confirming my research inference, we called several other parties that day together, if it is really the end of the world, the power of the two of us alone is still too small. I also need to ask them about their current situation to confirm whether my inference is valid. ”

Zhao Xinghua called several other people separately, because it is currently in the vacation stage, it is a rare vacation for athletes who are undergoing closed training all year round, only four people can come over in Suishi, and the others go back to their parents' house or go to their girlfriends.

Half an hour later, Gao Liexiong of the orienteering team arrived first, and asked for a dozen beers for himself, but Yixi of the archery team came with his girlfriend, whose girlfriend was named Zhang Ying, and he was a junior at CUHK. Zhang Rui came alone, he has been depressed recently, he is very self-motivated, and wants to become the main member of the national climbing team, because he is 25 years old, and he is about to pass the peak stage of physical fitness for an athlete's age. But seeing the explosive progress of his climbing skills, he didn't have the opportunity to show it, and everything was ready. Wang Haiyang of the foil team and Wang Liang of the rock climbing team finally arrived at the same time, and Wang Haiyang also brought a friend, who introduced him as his former classmate, who is now working as a manager in a financial institution, named Li Zhi.

When the personnel arrived, they greeted each other and talked for a while, Zhao Jie signaled that he had something to say, because Zhao Jie was the oldest here and the most reliable person, and everyone still respected him.

"Now I'd like to ask you about your recent physical condition, and then have a theory of my own that I want to tell you." Zhao Jie officially opened.

Gao Lie Xiong was the first to express his position, saying: "Let me say it first, I can clearly feel the change in my physical condition, because I am engaged in orienteering, every time I go out to a certain destination, I am used to it as a drill, even in the city, this is a habit developed for many years, of course, I will not run and climb, but just plan the shortest route for myself and confirm the direction without using a compass." In the last few times I can feel a big change in my overall sense of orientation and fitness, I should say stronger, and if I had to describe it by a quantitative standard, I think I have improved by more than 30%. "Gao Lie Xiong is usually honest in appearance, but he is indeed a very careful person. Zhao Jie was very satisfied with Gao Liexiong's description and recorded it in his notebook.

"I would also like to say that since I have recently taken a vacation I can only go to the archery club to practice, and it is obvious that there is a big leap in archery, yes, a leap, and I don't think I can sum up my progress if I just use the word progress. And my eyesight is also a leap now, I don't want to use ordinary words to describe it, because I haven't deliberately experienced what the limit of my eyesight is, but it must be much better than normal people's eyesight. After saying that, her eyes looked at the beer saleswoman at the door, and Zhang Ying grabbed his ear and pulled it back.

Wang Haiyang continued: "My bounce and speed have also improved a lot, I can't compare them in a specific way like Gao Lixiong, but the improvement must still be great, and I am now sure that if I play, my opponent will not be able to stab me." ”

Wang Liang also said: "I haven't trained since I came back, but now my arm strength and finger strength are much greater than before, and I found it when I was exercising in the gym, and I was surprised by it for a few days." Is there any common reason why we see everyone improving dramatically now, Dr. Zhao? ”

Zhao Jie replied: "Yes, it was all caused by the accidental meteorite fragment that day. ”

Li Zhi, who was observing, had not spoken, and when he heard this, he began to focus his attention completely on this side. In his opinion just now, he thinks that it is the effect of these athletes after going to the plateau to participate in the training camp, because the altitude training in various countries is, to put it bluntly, to increase the human hemoglobin, which is similar to the existence of physiological stimulants. Hearing Zhao Jie's inference surprised him.

Zhao Jie continued: "The next words are just my personal inference, you can listen to it as a science fiction novel, believe it or not, and don't spread it after listening." Because my inference cannot be explained by the scientific scope of the current world, I myself think it is very absurd. ”

"Those fragments of meteorites we picked up, I believe they are preserved except mine, and yours are all gone, right?"

"If it weren't for taking pictures at the time and posting them on Moments, I would have thought it would have been a dream." Wang Liang continued.

"So it's a strange thing, a meteorite fell from space to the ground, and the friction through the atmosphere did not burn out, but later volatilized at room temperature. This question has also been bothering me when I was at the base. It wasn't until I returned to Suishi that I went to the laboratory of Ji University and conducted experiments, only to discover the weirdness of this meteorite, or it can't be said to be a meteorite, because it is alive. ”

Everyone was stunned, but no one interjected, waiting for Zhao Jie to continue.

"I put the stone in a confined space, and found that it was still in its original state, I knocked a piece of it in the airtight box, put it in another airtight container with liquid water, it melted quickly, I took a drop of the liquid of the water, put it under the microscope and found that there were many tiny organisms in the water, more precisely, virus-like species."

All the others gasped, and their hairs stood on end, could it be that they were infected by the virus, everyone had such a thought in their hearts.

Zhao Jie continued: "Don't worry, not all viruses are deadly, the so-called virus is called a virus because it is similar to the structure of viruses on the earth, it is a non-cellular form composed of a nucleic acid molecule (DNA) and protein, and it is an organic species between living and non-living organisms that live by parasitism, and it is a special organism without a cellular structure. It is a mechanism by which a piece of DNA wrapped in a protective shell is infected, and these simple organisms can replicate themselves using the host's cellular system, but are unable to grow and replicate independently. Viruses can infect almost all living organisms that have cellular structures. Viruses are highly parasitic and completely dependent on the energy and metabolic systems of the host cell, obtaining the substances and energy needed for life activities, leaving the host cell, it is just a large chemical molecule, which stops its activity and can be made into protein crystallization, as an inanimate body. ”?

"Meaning we're parasitized by viruses from outer space?!" Wang Haiyang asked in a trembling voice, hearing this, Li Zhi also lowered his intention to stay away from everyone.

"Don't be afraid that many of the genes of human beings are obtained from viruses, which play an unusual role in the process of human survival and evolution, and humans and vertebrates have obtained more than 100 genes directly from viruses, such as the enzyme system that copies DNA from humans themselves, and may also come from viruses, which are the promoters of the evolution of life and the support for the normal operation of the entire ecosystem. There are as many as 100,000 fragments in the human genome from viruses, and these viral gene fragments account for 8% of the human genome. ”?

When everyone heard this, they breathed a sigh of relief at the same time. This time, no one asked any more questions, and they all waited for Zhao Jie to continue.

"These viruses should be said to be benign and can help organisms to evolve genetically, but I can't speculate to what extent."

But at the same time, there is another uncertain factor, I don't know under what circumstances some organisms evolve in a benign direction, such as you. Some will turn into zombies, for example. After that, he looked at Zhao Xinghua, but Zhao Xinghua didn't take it seriously.

Yixi's girlfriend and Li Zhi heard the zombies and let out an "ah" together, feeling more surprised than they had just heard them become stronger.

"We have seen zombies in the plateau base, the previous nurse Jia Lili and a few who invaded at night later, Yixi's arrows were shot, and finally the zombie's heart was pierced." Hearing this, Zhang Ying looked at Yixi with adoring eyes, and seeing this situation, Zhao Jie did not continue to talk about the result that the arrow did not work.

"Doctor Zhao, you haven't said why the meteorite or virus combination did not burn at high temperature, but disappeared at room temperature, and we didn't put the meteorite or virus into the water?" Gao Lixiong found a question and asked.

"Yes, at that time I also wondered why in a closed box, it did not dissolve or volatilize, but when it came to water, it melted. The heat is high and it doesn't burn out. Zhao Jie asked himself.

"I took the big piece out of the sealed box again, and held it in my hand, I wanted to observe the change process with the naked eye, and when I took this solid virus combination into my hand, I found that soon the outermost layer of material was softening, and then soon the whole piece disappeared at a speed visible to the naked eye, and when there was still the last small piece, I quickly put it back into the closed box, and it stopped changing."

"Doctor Zhao, does it mean that you are now infected by the same virus as us? Hehe. Zhao Xinghua let out a wicked laugh.

Zhao Jie glanced at him and said, "It should be said that it is the same as them, not the same as you." ”

"I think it should be viruses that dissolve parasitism when they encounter a certain environment, and it should be that they have a prefabricated function that can distinguish whether the surrounding environment meets the parasitic conditions, such as temperature, humidity and air flow. As I expected, as I ventilated the airtight box, it began to soften again, ready to drift away with the airflow. When I approach them with flames, they harden again, and they secrete something like a substance, or this virus is not made up of proteins like our planet, but a molecule that we don't know, and it can protect itself in extreme environments. ”

"This is also why countries did not warn of the meteor shower in advance a few days ago, because normal meteors began to burn when they entered the atmosphere, and they basically burned out after the ground, and the normal monitoring instruments only monitored those meteorites with huge volumes, and the volume of these virions reaching the ground is the volume of their initial entry into the atmosphere, which is only the size of a football, and instruments and equipment on the earth cannot detect their arrival."

When everyone heard this, they were silent for a long time, unable to fully digest this unbelievable inference.
