The word hibernation in biology, usually refers to some animals by reducing their metabolic levels, to survive the cold temperature, difficult to obtain food winter, in many science fiction novels, the word is usually the image of stuffing people into a freezer, after a period of time to take out and thaw, history is said to have such an example, it is said that a person was frozen in the snow mountain decades ago but did not die, and was later found alive - although the current science and technology can not do this, The human body contains a lot of water, and freezing will increase the volume of water in the cells, causing irreversible damage to the cells, but Han Le has always believed that this day will not be far away - but, when this fact really happened to him, especially when Qiao Yiyu said this advice in front of him, at that time, he still couldn't help but wonder if he had heard it wrong.

There were not many people on the train back, Qiao Yiyu sat opposite him with one hand on his chin, and was slowly explaining to him the principle and process of hibernation: "This is a backup mechanism of the artificial immune system, artificial bacteria can regulate the body's endocrine by automatically synthesizing chemicals, and greatly reduce the level of metabolism to maintain life...... Its security is absolutely reliable, and the process is not complicated. First of all, let's go into hibernation together, because the whole mechanism relies on chemistry, as long as I command the artificial bacteria in your body, you can do it, cut off our physical practice after making sure that the hibernation is complete, and then I wake up, in the hibernation state, the artificial bacteria in your body will always maintain the synthesis of related chemicals, so that you can always maintain the hibernation state. ”

Han Le thought about it carefully, and after roughly understanding, he asked: "Then there is no need to cooperate with the cooling and the necessary sterilization ......."

Qiao Yiyu patted his head: "I didn't think about this...... If I hibernates, I don't need this, because my artificial immune system will work, as long as the surface of my body is clean and there is a small amount of air, but you ...... In this case, we have to buy a refrigerator......"

Han Le still couldn't avoid worrying: "Won't the low temperature freeze me to death?" When he said this, the "I" in Han Le's mouth seemed to be a stranger, and he didn't look angry at all.

"No," Qiao Yiyu said, "this mechanism already has an antifreeze function. ”

Han Le carefully guessed with his own science fiction background: "Is it for use in space?" ”

Qiao Yiyu glanced at Han Le with some surprise: "Yes...... You're very responsive. ”

"Your time...... Do people still live on Earth? Han Le was a little bolder.

"No," Qiao Yiyu shook her head, "but it's still in the solar system." ”

"And are there any people on Earth?"

Qiao Yiyu glanced at Han Le deeply and didn't answer the question, Han Le understood this look - not that he didn't want to tell him, but asked, "Are you sure you want to know?" Han Le thought about it or forget it, he was able to accept the suggestion of hibernation largely because of his expectations and imagination for the future, if the future was just a sentence from Qiao Yiyu's mouth, it would be too boring - it would only add to his troubles.

"Then how long will I probably hibernate," now that he had decided to accept it, Han Le felt that it would be better to ask the question clearly, "Wait until my illness can be cured?" ”

Qiao Yiyu nodded, he could understand Han Le's concern: "It may take a long time...... I can wake you up a few more times in the middle, if you want. ”

Han Le originally subconsciously wanted to say that it was not troublesome, but after thinking about it, he still didn't say it, after all, it was difficult for him to imagine what it would be like for him to wake up for a few years, or even decades, if he could, it would be better to adapt more, the future may not be happy - if he woke up and happened to encounter war or famine, it was better to lie in bed and wait for death as soon as possible.

After getting off the train, I took the subway back, inevitably passing by the milk tea shop, Zhang Xin and Sun Xiaoyun were very busy, during this time because of Han Le's problem, Qiao Yiyu almost handed over the entire store to them, according to the new commission method, two people can almost raise three or four hundred yuan a day - even five or six hundred at the peak, and the commission for ten days is higher than the salary in the past two months,

The two were obviously a little caught off guard when they saw Han Le, according to the previous statement, Han Le was their leader, if he came back to work, then maybe life would return to the past, but after chatting a few words, this little worry was gone, Han Le laughed at himself that he was going to spend a few years traveling - this is not a lie, travel in time, Han Le himself thinks so.

"Brother Han, if you don't die this time, you will have a blessing," Zhang Xin said with a grin, and then pointed to the next door a little mysteriously, "I heard that their leader is still in the hospital and hasn't come out."

mentioned Zhu Yuxiang, Han Le remembered that he didn't know his situation yet, Qiao Yiyu knew a little: "I heard that I just heard about the dangerous period, and the recovery is okay." In fact, Zhu Yuxiang woke up and kept calling and texting her, saying that every time he had a high fever in the hospital, he had the courage to fight the disease as long as he thought of Qiao Yiyu...... Qiao Yiyu could only smile at this.

Zhu Yuxiang, Zhou Hai, Radish Head...... I don't know how long these people can hold on for love after they "hibernate", and without themselves, will Qiao Yiyu find a fake boyfriend again? On the way home, Han Le was thinking wildly.

After arriving home, Qiao Yiyu went online to check the news about the freezer, and asked Han Le to refer to which one is good, many products have food displays, and most of the freezers that can be placed next person are used to store food.

The freezer that can meet the requirements is basically the same as what Han Le has seen in the supermarket, which is very different from Han Le's previous imagination of hibernation - whether it is in movies or TV, cryonics seems to be a very complex technology, not to mention that the body has to be filled with various tubes, and it has to lie in a special nutrient solution, but the image Qiao Yiyu showed him is largely no different from a dead pig placed in it, which is also an important reason why he has never been able to rule out his fear of hibernation.

"In fact, the dormancy technology is really not complicated," Qiao Yiyu prefers to call this technology hibernation, because this technology does not take the path of animal hibernation in bionics, "as long as it solves the problem of human tissue structure not being destroyed, as well as bacterial infection, although low temperature can not eliminate 100% bacteria, but you have artificial bacteria in your body, I can do sterilization for you every few months, or half a year......

"I didn't disbelieve you," Han Le said to Qiao Yiyu, "I just ...... A little scared, give me a few days to get used to it. ”

Qiao Yiyu's efficiency was very fast, and the next afternoon, he commanded a few workers to move a huge freezer into the living room - because the door of the room was too small, so it could only be placed here, obviously, this was different from Han Le's imagination, he felt that he should be in a closed cabinet when he hibernated, not like a great man - the living room obviously has this public attribute in a sense, although this is his home, maybe no one will come in after he falls asleep.

Han Le stared at the big guy in the living room, his eyes were like looking at his crystal coffin, and when Qiao Yiyu was away, he also secretly went in and tried the feeling - hard, very cramped, and completely different from sleeping in bed, because both sides were closed.

After Qiao Yiyu came back, he checked his body as soon as possible, and then asked him with a frown: "How do you feel about your body in the afternoon?" ”

Han Le touched his forehead: "It seems that the weather is a little hot." ”

Qiao Yiyu glanced at him worriedly: "It's because you have a low-grade fever, and you haven't noticed it yet...... But don't worry, it's just a slight infection, not a big deal. Han Le knew that if Qiao Yiyu was not there, it would easily become a big problem.

Han Le originally wanted to argue that I was at home all day, but he still didn't make a sound, even if he stayed at home and didn't move, as long as he was still breathing, his body would inevitably come into contact with a large number of bacteria, which made him realize that it was really not too romantic to tie his own safety to Qiao Yiyu - for Qiao Yiyu, he was a burden, even for himself, he could not completely lose his freedom and live dependent on Qiao Yiyu. It's like love and marriage, the former is consciously voluntary, but even under this premise, once it becomes marriage, that is, with a part of external coercion, the relationship will unconsciously begin to deteriorate, from rights to obligations - no one likes obligations.

And in a large sense, the binding force of this relationship between Han Le and Qiao Yiyu is much greater than the coercive force of marriage - in the marriage, the husband and wife quarrel and separate or something, if Qiao Yiyu throws Han Le away, Han Le will lie in the morgue within a month. This kind of restraint is equivalent to losing personal freedom for Han Le, and it is also a huge moral burden for Qiao Yiyu.

"Or," Han Le hesitated for a long time while eating, "I'll hibernate tonight." ”

"Have you done everything you have to do?" Qiao Yiyu said, thought about it again, "Have you told your family?" "This is a problem that must be considered, if Han Le does not appear for five or six years, or even seven or eight years, it will definitely arouse the suspicion of others, even if he has made a will in advance, the possibility of accidents cannot be ruled out, and it is still a trivial matter to fight a lawsuit for the inheritance, but if Han Le is found to be hibernating at home, he will definitely not be able to hide it.

"I've called." Han Le nodded. To all the people he knew, Han Le said that a serious illness made him realize that life is too short, so he decided to travel around China - he also specially found a bunch of travel articles to post on his QQ space as evidence. Based on his experience at home in the past few years, no one should come to contact him - this also made Han Le feel quite pathetic, and he found that he seemed to be completely disconnected from this world.

"As long as you feel like you can, then tonight."

……

After dinner, Han Le went to the barber shop in the community to push himself a short flat head, and after coming back, he took a serious bath, and finally got into the quilt naked, staring at the door in a daze, he knew that according to Qiao Yiyu's plan, he would come over after he fell asleep, and on this bed, he would go into a dormant state with him, and the whole process was said to take three to five hours, and during this period, he would sleep more and more deeply - and finally sleep no different from a vegetative person.

After that, Qiao Yiyu will wake himself up, and then put him in the freezer, and after 24 hours, he will be completely frozen into a whole piece of frozen meat inside, and Qiao Yiyu will monitor the room for three days to make sure that there is no big accident - but Han Le feels that this is no longer important to him, because he will not be conscious at that time, even if he dies by accident, that is, he will die, and he will not be in pain, so he will be treated as if he died in the hospital at that time.

Qiao Yiyu mentioned that dormancy was a common behavior in her time, just like people nowadays go to travel - travel is to designate a place, dormancy is to designate a certain time, and in space, the two often coincide, the speed of light barrier always exists, and the meaning of time and space is almost the same for people.

The more he thought about this question, the more Han Le felt that he couldn't sleep, the huge fear and curiosity made his heart pound, and he began to subconsciously think about what it would be like when he woke up, whether he would open his eyes and see robots, open the window and see the sky full of flying machines......

I don't know how long it took, the door was opened, and Qiao Yiyu, who walked in the door, glanced at Han Le: "I thought you were asleep." ”

Han Le didn't know what to answer, and at this time, Qiao Yiyu sat down next to him and asked him, "Do you want me to help you?" ”

"Are you still hypnotic?" Han Le smiled stiffly.

"No, it's artificial bacteria that have the function of synthesizing hypnotic drugs."

Han Le nodded slightly, and then Qiao Yiyu's slightly warm hand covered his forehead, and then Qiao Yiyu lay down beside him, Han Le understood at this time, just like if she wanted him to hibernate, she had to hibernate herself, and hypnosis was the same.

Gradually, Han Le felt relaxed, because the tension caused by the ambiguity of this action receded like a tide, and the gentle warmth and comfort started from Qiao Yiyu's hand, and gradually spread to the whole body, Han Le turned his head, took one last look at Qiao Yiyu, and then closed his eyes. Consciousness gradually began to drift and diffuse in this comfort, and the thoughts that had been echoing in my head just now disappeared one by one like soap bubbles, and finally turned into nothingness.

Four hours later, Qiao Yiyu woke up first, gently leaned his face to listen to Han Le's breathing—almost inaudible, and his chest did not rise and fall at all, which showed that hibernation had worked. Qiao Yiyu took a look at the time, April 15, 3 a.m., 2013.

Han Le's body was not heavy, and Qiao Yiyu didn't feel too difficult to pick him up, but because the freezer was not particularly large, it was inevitable that she bumped twice when she put it in, and the auxiliary system prompted her to apologize, but Qiao Yiyu knew that she didn't need it.

The refrigeration process is carried out slowly, from the ambient temperature of 24 degrees to 3 degrees, Qiao Yiyu has been relying on hand testing and operating switches to extend the time, to ensure that the ambient temperature and body temperature have been falling synchronously, more than ten hours later, Han Le's low temperature reached a predetermined value and stabilized, at this time his body surface was covered with a layer of light frost, if there was a third person present, he would not think that Han Le still had the possibility of being alive, thinking that this was the first scene of Qiao Yiyu's murder.

Using a CPU fan on a computer and two conduits, Qiao Yiyu made a simple ventilation device to prevent carbon dioxide from being deposited under the freezer for a long time and causing hypoxia, after doing this, Qiao Yiyu knew that her work was basically done, she closed the windows of the room, locked it, closed the curtains, and then took out her suitcase from the room, closed her eyes, and let the box be like a liquid, and slowly soaked the freezer, like coating the entire freezer with a metal film- The film can achieve a breathable effect while blocking most of the bacteria, and at the same time prevent intruders from seeing Han Le in it, if someone plans to use a hard method, Qiao Yiyu will also know at the first time.

The next thing to do is to wait, it is not difficult for Qiao Yiyu, she turned on Han Le's computer, found a few games that she had seen Han Le play and began to play - originally Han Le said that he would teach her to play together, but unfortunately found a suitable opportunity.

The next morning, Qiao Yiyu received a call from Zhu Yuxiang, in which he said that he had been discharged from the hospital, Qiao Yiyu congratulated him, and then told the other party that he was now at the airport and was going to travel to other provinces with Han Le - before Zhu Yuxiang asked them where they were going, he hung up his phone.

Zhu Yuxiang came once in the afternoon and knocked on the door for half an hour, but no one responded, and at noon the next day, Zhou Hai also came over once and knocked on the door the same, but no one answered.

In the evening, Zhang Xin called, it was about reconciliation, Qiao Yiyu said that he was not free in the past few days, and asked him to stay first.

On the third day, Qiao Yiyu found a diesel generator on the Internet, and it was delivered to the door less than five hours after placing the order, and the workers were a little surprised what the big cabinet in the center of the living room was, Qiao Yiyu only said that it was a laboratory material - it needed to be kept refrigerated, so it was necessary to make a set of backup power supply. Although it is unlikely that Shenhai will lose power, it is also necessary to take into account the unexpected.

Early in the morning of the fourth day, Qiao Yiyu checked his wallet, keys, and mobile phone as usual, but after going out, he folded back and put an electronic clock on Han Le's bedside table next to Han Le.

The sun was shining outside, the freezer was cold, and objectively time was not treated differently because of this. It's just that for the current Han Le, time has stopped the moment he fell asleep, but for Qiao Yiyu, it has been going on - the fate of the two people has a small fork here, Han Le is unconsciously waiting to wake up one day in the future, and Qiao Yiyu will continue her ancient life in the 21st century.
