"When I was pushed out by the doctor yesterday, I really thought I was dead," recalling the near-death experience last night, Han Le still has palpitations, and after being able to speak, as if he was deliberately trying to prove that he was still alive, he began to say endlessly, "I can't feel that I still have a heartbeat and breathing, and I feel like I have lost my weight and float in the air...... I finally know where some out-of-body experiences come about......"

Qiao Yiyu just listened quietly on the edge of the bed, and when Han Le spoke, her hand kept pressing on his back, looking like she was helping him.

"I heard from the nurse that you saved me with serum?" Han Le began to care about the reason why he survived, "Is it because you future people have immune antibodies?" ”

"Sort of." Qiao Yiyu said a word, she didn't want to explain this problem in detail, technical problems are a lot of things, and it is basically impossible to explain the principle of each link clearly.

At more than 7 o'clock, a group of doctors gathered around Han Le's bed, and their eyes staring at Han Le made him a little panicked, one of the older ones took the medical record card in front of Han Le's bed, read it again very seriously, and finally asked him and Qiao Yiyu: "Really except for serum, you haven't used any other drugs?" ”

Qiao Yiyu nodded: "No, we just tried it randomly, I heard on the Internet that this might work, because I wasn't infected, I think it might be because I have antibodies in my body......"

A group of doctors turned their heads to each other, this kind of discussion has been going on for a while in the office just now, Qiao Yiyu's serum They have also appropriately extracted some of the try, and even done basic experiments in the laboratory, but they have not achieved such a "miraculous" antiviral and recovery effect as Han Le's body, so the doctors' opinions on how Han Le suddenly got better - after excluding the serum, that is, the previous conventional treatment measures, there is no difference between Han Le and other patients, It's just that doctors will focus on medication according to the actual situation of the patient.

As for what Qiao Yiyu said, it is just a simple folk statement, whether there are antibodies in the serum of the uninfected person, considering Han Le's condition last night, even if there are antibodies, it will not have much effect - by that time, the virus is no longer the most critical factor that threatens life, the destroyed immune system, sepsis, and large-scale bacterial infection are the most fatal keys, and the doctors are concerned about whether in this process, whether it is because the patient mistakenly uses any home remedies to produce an ultra-high-efficiency bactericidal effect- But judging from the words of the nurse and Qiao Yiyu, it seems that this situation does not exist, maybe everything is just an accident - such examples in medicine are not impossible, but relatively rare.

Now Han Le's physical condition has basically returned to the condition of three or four days ago, although it is still in a dangerous period, but the situation has begun to improve significantly, and the most surprising thing for doctors is that this improvement seems to have regional characteristics, such as the chest area that first recovered, Han Le's lung inflammation has basically disappeared now, and it has metastasized to the abdomen after a few hours - the nurse guessed that the reason for this situation may be because of Qiao Yiyu's "massage", but this statement was scoffed by the doctor, if the massage can kill bacteria, So what do you need a hospital for? Just ask a few masseurs to come. This phenomenon may be understood as a psychological effect that can barely be said to be in the past.

But no matter how much the doctors don't understand, the recovery of Han Le's physical condition is indeed an indisputable fact, in the morning, Han Le also drank a big bowl of soy milk, and after eating, he was hungry and wanted to eat - but he was stopped by the nurse, because of the previous vomiting and inflammation that has not subsided, Han Le's gastrointestinal function is likely to have not recovered, and the doctor needs to observe the next reaction.

After the doctors left, Qiao Yiyu suddenly looked at the window and yawned loudly, at this time Han Le noticed that Qiao Yiyu's spirit seemed to be worse today than before, so he asked, "You didn't sleep yesterday?" ”

"Hmm." Qiao Yiyu nodded, she had spent most of the past 24 hours studying information about the artificial immune system, and she had to pay attention to the situation in Han Le's body at any time since the injection of serum, so she couldn't even spare the two hours of sleep.

"Then you go to sleep first," Han Le said embarrassedly, "You see I'm fine." ”

Qiao Yiyu shook his head: "Don't worry, I'll go to sleep in the afternoon." ”

Han Le noticed at this time that from the time he woke up to the present, Qiao Yiyu's hand had never left his body, of course he would not think that this was Qiao Yiyu's intimate act with himself, so the explanation was obvious: "Is this related to my illness?" ”

Qiao Yiyu didn't answer, just nodded, she didn't want the nurses and doctors to know the news, in that case, it would be really endless, and after a while, she just whispered to Han Le, "I'll tell you later." ”

Han Le naturally understood that Qiao Yiyu's motive was to keep it secret, so he didn't ask again, but after waiting for a while, he saw Qiao Yiyu leaning on the edge of the bed, and after dozing off unconsciously, he still suggested: "Why don't I change my position, you can sleep on your stomach, this ...... Does it have an impact? ”

It doesn't have an effect, the artificial immune system runs automatically, and this is not a martial arts novel that uses true qi to force poison - but it seems that it still has an effect, there is still a lot of imagination, so Qiao Yiyu lay on the side and began to doze off, but she told Han Le to pay attention to the body to maintain contact with her hands, it is best to change positions every once in a while, she dare not guarantee that Han Le's condition will suddenly recur.

Maybe she was really sleepy, maybe it was because of her good sleeping habits, Qiao Yiyu fell asleep quickly, Han Le adjusted her sleeping position slightly, turned her head to the side of Qiao Yiyu, and watched Qiao Yiyu put her head on her other arm, and her long breath hit the surface of the protective suit, condensing a slight mist. Because of the barrier of this fog, her face was not as real as usual, but Han Le felt that Qiao Yiyu at this time was more real than anything he had seen before, and through the gloves, he could even feel the other party's warm body temperature.

Even Han Le himself didn't realize that he could barely move his gaze away as soon as he touched Qiao Yiyu, if Qiao Yiyu was awake, maybe Han Le would have restrained his gaze a little, but now, even if the nurse came to check on the situation, he was unwilling to move his attention away from her face. Thinking of his previous thoughts of thinking that he was high and wanted to keep a distance from Qiao Yiyu, Han Le scolded his hypocrisy in his heart for the first time - if he really did what he thought at the time, and consciously kept his distance from Qiao Yiyu or even cut off the relationship, what a great regret it would be in life!

……

In the next few days, Qiao Yiyu would come to Han Le every day to give him a four-to-five-hour "massage" to recover from his illness as soon as possible, and the facts proved that this did have extraordinary effects. On the second day after he got better, Han Le's test report showed that he no longer had any avian influenza virus in his body at the moment, which means that he can be transferred from the isolation ward to the general ward, and then he can go through the discharge procedures as long as the inflammation in other parts of the body completely disappears and the body indicators return to normal.

This is undoubtedly good news to celebrate, but Han Le noticed that no one seemed to be in high spirits for the news - several relatives were almost numb and disbelieving when they listened to the doctor's introduction of this "medical miracle", because these words were equivalent to saying that their waiting and expectations for the past few days had all come to naught, and some of them even contacted real estate agents...... Even Qiao Yiyu only smiled reluctantly after hearing the news, and her attitude made Han Le feel a little uneasy.

On April 12th, on this day, Han Le felt that his body had fully recovered, although he still felt a little weak, but he did not have the high fever and discomfort from time to time when he was admitted to the hospital, when the doctor was rounding, he asked the doctor when he could be discharged, the doctor looked at his test list today, frowned - and called the nurse over: "This data is correct, right?" ”

"That's right?" The nurse took it and checked it again, "What's wrong?" ”

"Why can't the white blood cells go up," the doctor whispered to himself, and then explained to the nurse, "I will do a blood test for him at 12 noon, and the report will be sent directly to me." ”

Then he turned his head and smiled at Han Le: "Don't worry, it's not a big problem, it's just that we have to observe for a while." ”

"How long will you be observing?" It was the same thing two days ago.

"It depends on the speed of recovery, don't worry, anyway, this epidemic is also paid by the state." The doctor thought that Han Le was worried about the hospitalization fee.

Qiao Yiyu was next to him while speaking, and after the doctor left, Qiao Yiyu said to Han Le: "I'll help you out for a walk, I have something to tell you." ”

Han Le realized that what Qiao Yiyu was going to say was probably related to the abnormality that the doctor said, and it was also likely to be related to her behavior of saving herself, Qiao Yiyu had not responded positively to this question in the past few days, and she didn't ask herself—he knew that she would naturally say it when Qiao Yiyu thought she needed to say it.

Han Le had been in the ward for too long, and when he came in, it was still just spring, and it seemed a little cold, but now that the temperature has become fast, Han Le, who deliberately came out with a few more clothes, found that he felt hot. In the hall, Han Le saw several reporters carrying cameras negotiating with a group of nurses and security guards, asking them to disclose the specific casualty figures......

Han Le was actually able to leave by himself, but in the past few days, because of the inertia he had developed from "curing the disease", he still habitually let Qiao Yiyu's hand stick to his body, as if doing so could bring him a great sense of security. After the two of them went downstairs, they didn't go far, they found a stool and sat down under the shade of a nearby tree, and within a few seconds, Qiao Yiyu said: "Han Le, although I had to save you at that time, I was tantamount to harming you by doing so." ”

Han Le shook his head: "I don't know what you mean by hurting me, but I know that if it weren't for you, I wouldn't be sitting here talking to you right now, but being bowed to in an urn." ”

Qiao Yiyu didn't accept Han Le's comfort, but slowly began to talk about her worries: "I'd better tell you about the artificial immune system first, so that you can have an understanding of the problem......

This knowledge is actually not complicated, and it may not be as much as the knowledge points mentioned in a biology book, and Han Le has no difficulty in understanding it, he still participated in a biology knowledge contest when he was in high school! What Qiao Yiyu said is actually no more difficult to understand than human biology - it is just that various effector cells have been transformed into nanomachines with special functions, and the process has changed from a spontaneous complex stress response to a strategy developed by a program and monitored by a calculator.

"Will these robots reproduce on their own? Will it turn into another Resident Evil or something? In the process of listening to the story, Han Le's thinking was too divergent, and he didn't care about himself, but about human beings.

"Theoretically, no, although the mechanical structure of these artificial bacteria is small, but without the premise of computer instructions, there is no function, it is no different from nano dust, in my time, because this process has even gone a lot of ways, so it is very strict." Qiao Yiyu explained.

"But because of this, there are many strict restrictions in the use of the artificial immune system," Qiao Yiyu continued, "that is, one system is not allowed to be used on two different people unless it is absolutely necessary, because the whole system is tailored according to the inherent immune information of the human body, and if we are in this situation, there will be certain sequelae." ”

Han Le felt that he had already guessed the answer, combined with some biological knowledge he knew, as well as what the doctor had just said: "Is it going to attack the human immune system?" ”

"That's not the point," Qiao Yiyu shook his head, "This does happen at the beginning, but the behavior patterns of artificial bacteria can be regulated by the system, and if the regulation is not done well, they can also be inactivated by interrupting the command...... The bacterial communication process is carried back step by step through energy and its subtle, fixed-frequency electromagnetic waves, up to a few centimeters allowable for interruption, so it's easy to do this. ”

Then Han Le couldn't guess, so he could only listen to Qiao Yiyu continue.

"The point is that the body's immune system will actively attack the bacteria, because they don't have the matching glycoprotein information in their body, and this immune information is only linked to the implanted person's genes. However, these bacteria are artificial structures, and their structural stability is much higher than that of ordinary cells, so there is no way to be eliminated by the immune system. Immune cells, mainly white blood cells, will only attack in vain, and then one by one they will die of indigestion...... For the human body, this foreign substance is simply another virus. ”

"Won't they decrease with metabolism?" Han Le understood what Qiao Yiyu said, this is similar to a weakened version of AIDS, except that the HIV virus attacks the immune system actively, while this "virus" is passive, but the results are the same - at most, this virus is weaker. Strictly speaking, it is more similar to transplant rejection. But they are not viruses after all, if they do not carry out any activities as Qiao Yiyu said, of course, including proliferation, then they will definitely gradually decrease with the body's metabolism.

"The artificial immune system is designed with this factor in mind, and in order to avoid waste, it is minimized because the raw materials for the manufacture of this bacterium are not provided by the human body itself...... This kind of bacteria in the human body will automatically attach to those important organ cells around, very fixed, only in the process of sterilization will be in a free state, according to my calculations, according to the normal level of human metabolism, the number of bacteria in your body may take more than 30 years to completely metabolize......"

"More than thirty years!" Han Lexin said that if AIDS can live for so long, then AIDS is not so terrible.

"So what do you mean? I'm still hopeless? Han Le was still overshadowed by these words just now because of the joy of escaping.

"Don't be so pessimistic," Qiao Yiyu shook his head, "At least there is no danger in the short term, and even if you are infected with other diseases due to weak immunity, I can temporarily replace the immune system with these artificial bacteria." ”

After Han Le heard this, instead of feeling sad, he was a little excited: "Then do you mean that as long as you are not near me, I will be very dangerous?" ”

"That's what it means," Qiao Yiyu said, and then she noticed Han Le's somewhat abnormal attitude, "Why are you so happy?" Did you know that if I wasn't there, maybe a common cold would kill you? ”

Han Le secretly muttered in his heart: "Then I'll follow you all the time." ”

Although Han Le didn't say it, it was not difficult for Qiao Yiyu to detect his intentions, and she understood it after a little thought-after understanding it, she could only shake her head and smile bitterly, the ancients were really ...... Even things that matter your own life will be linked to love regardless of importance.

"Low immunity is just one of the possible outcomes," Qiao Yiyu coldly used the relevant knowledge he found on the Internet to break Han Le's romantic fantasy, "It is easy to have fever, malnutrition, and it is possible that it will cause infection due to long-term lack of white blood cells, which will induce other diseases or tumors during the period...... Just the fever, think about the sins you've suffered these days. ”

These few words made Han Le regain his consciousness a little, thinking about the days he had spent in a high fever during this time, it was really ...... Han Le naturally knows that the opportunity to come into contact with viruses and bacteria in his life is almost every moment, even if he stays at home every day, he can't avoid it, unless he is like a foreign glass baby, he builds a sterile room for himself, all meals must be strictly disinfected, and he goes out to wear bubble clothes......

Not to mention whether the cost of realization can be afforded, just imagining such a life model, Han Le feels unacceptable, if that is the case, he must be crazy.

"Is there a solution to that?" Han Le asked with a glimmer of hope.

"There is always a way," Qiao Yiyu looked at Han Le and said, "but it depends on how far you can accept it." ”
