Gu Yunxuan continued: "Speaking of which, the terrible thing about the XV virus is that it can cause harm to the human body. After a normal person is infected, the body will lose the ability to move within a few weeks, and the reduction of ATP is just that, the brunt of the destruction of neuronal cells will be incapacitated, and finally lead to muscle stiffness, atrophy and death of the whole body. This characteristic of the disease is very similar to the later "ALS" disease, and some medical experts even believe that the formation and onset of ALS symptoms are greatly related to this XV virus. It is necessary to treat these two diseases differently, whether in terms of clinical experience or the summary of historical legacies, so that medical workers are at a loss, and they are completely unable to explain the independence of the two sets of theories......"

"Teacher, wait a minute!" Lin Han interjected at this time: "I can't be infected with this XV virus!" Because according to your description, this virus is invisibly transmitted to everyone anytime, anywhere. But I found that everyone around me was not performing like me, and they were all very healthy...... If I really carry this terrible virus, wouldn't it be ...... Isn't it ......?"

Gu Yunxuan smiled and nodded, explaining, "Your illness, the key point is this, it is a special case. The first thing you should think about is, if you can really pass the virus on to others, how can I still contact you in such a dangerous situation? Even if I'm tired of being old and alive, but Gu Wei is still young, how can I ask her to contact you too? Actually, it's easy to understand, you've been sick for a long time, right? If it is contagious, I am definitely not the first to be infected, your friends, relatives, and colleagues have already been recruited, and it is my turn to be afraid? Since the people around you were safe and sound, it means that you don't see that you are carrying the XV virus, but it is not contagious, which I have thought about in advance. ”

Lin Han pondered and felt that the teacher's words were very reasonable. But there are many doubts: when did this hellish XV virus quietly infect him through something, and he didn't know it?

Gu Yunxuan saw his question and said, "I went through the information just now, and your situation has only been a special case in the history of XV virus research, and it is still a special case that cannot be verified. If the facts of the United States people developing, experimenting, and finally recovering and destroying the XV virus are still well documented, this special case can only be said to be a legend, and there is no evidence to explain its authenticity. I'm not sure if there are any parties or insiders in this world who have this special case. However, it is also an indisputable fact to say that it is a 'wild history' and cannot be annotated in a record book. ”

Lin Han asked, "Special case?" In other words...... Something that is as poisoned as I am but doesn't infect others has ever happened? ”

Gu Yunxuan nodded heavily, and said, "Ten years ago, I went to the capital to attend a seminar, and I was fortunate to meet a retired veteran cadre of the National Military Commission, who had been engaged in some project research in the biological field of the army before he retired. During this time, we talked about the XV virus, and the old cadres smiled and said to me, 'This thing should not have been invented and developed in the first place, and the people of the United States always mess with some big baskets'. I felt the same way, and I shared my limited research experience on this virus with him. At that time, I felt that this kind of research had lost its meaning, a virus that had disappeared from the world, and why did I continue to spend energy researching blindly? So when we talked, I was more relaxed and didn't have any responsible attitude. ”

Gu Yunxuan raised his head and recalled that period of history: "But the old cadre frowned, as if he was deeply worried. I wondered what he was looking at, so I asked why. The old cadre said to me, 'There is an unknown history, or a legend, or a fact, in short, there is no truth to verify, and it has always bothered me. My previous leader was an authentic soldier, and later was honorably promoted to general in the early days of the founding of the People's Republic of China, and his life was full of legends, some historical materials about the XV virus, and as a generation that witnessed it, he left a very rich and detailed record. It is a pity that during the ten years of catastrophe, he himself suffered many injustices and was labeled as a reactionary and anti-party. Not only was his body and mind devastated, but even his home was raided no less than three times. Many precious documents were either burned or lost and abandoned during the turmoil...... Subsequently, the general also suffered from a very serious liver disease and was sent to a local hospital for monitoring and treatment. When he was dying, due to the relationship between work and personal feelings, I took my men to visit the hospital, and the general took advantage of the unpreparedness of the people, secretly took out a pamphlet from under the pillow and stuffed it into me, although he did not say much, but his eyes were full of entrustment and hope. I knew that this booklet might contain something very important, and I quietly carried it into my arms. ’”

Lin Han asked, "Is this booklet related to the XV virus?" ”

Gu Yunxuan said: "Isn't it just related? The above is a brief XV virus memorabilia, and almost all the representative and typical XV virus records are on the record. The old cadre understands that the general is entrusting the legacy, and obviously he still has a lot of worries that he can't let go of about the XV virus. His life in this life may be coming to an end soon, and he can't do anything more, so he chooses to hand over such an important thing to his successor, that is, this old cadre. ”

Lin Han said: "What is recorded in the booklet? ”

Gu Yunxuan said: "Very fortunately, the old cadre handed me all the copies of the booklet and told me, 'You are one of the top authoritative scholars in the field of biology in the country, and the horror of the XV virus is not only that it can cause fatal trauma to people, but also that it cannot be prevented and cured. In the face of this virus, scientific research institutions in any country in the world are helpless, and there is no way to study and crack effective countermeasures. And you, undoubtedly, will have to take on this difficult task and find effective resistance and cracking methods against the XV virus in the next few years, ten years, or even in your lifetime. ’”

Lin Han said: "But the XV virus has disappeared from the world, is there any point in studying it again?" As soon as the words fell, I remembered that what I said was very inappropriate, and it was clear that my infected person was now real, and he was smeared by the XV virus, which means that the XV virus has not disappeared, and it must still be hidden in unknown corners of the world.

Gu Yunxuan said with a smile: "What you said is exactly the same as the reply I gave to the old cadres at that time. I distinctly remember him squinting his eyes slightly and asking me meaningfully, 'The people of the United States said that it disappeared and was destroyed, do you really believe it?' My heart shook when I heard this, and I immediately raised my guard. At that time, I may have been a little stupid to do academics, and I didn't know why it was. How can a country like the United States, which is hegemonic and profit-seeking, easily believe what it says? In addition, after World War II, the world pattern has undergone great changes, and many military powers have expanded their arms race and stored their military strength in a desperate attempt to store their military strength in addition to the Cold War. Hello to me, hello everyone, secretly all the time to monitor every move of the other side, for fear that the new technology and new tactics in the military field will lag behind. ”

Lin Han said: "This old cadre still sees it thoroughly, and in the end, he is the leader of the national level, and he can stand higher and think farther." ”

Gu Yunxuan nodded in agreement: "Speaking of the ability to have a keen political sense and analyze the direction of the international situation, there is a world of difference between me and this old cadre, and the difference is too far. I understood what he meant, and at the same time understood the true meaning of someone giving me such an important booklet. I solemnly accepted the copy he had given me, and prepared to come back and devote myself to research. While the veteran cadres told me to pay attention to secrecy, they also hoped that I could make a breakthrough as soon as possible and study a way to fight the XV virus as soon as possible. ”

Lin Han saw Gu Yunxuan's expression very depressed when he said this, and asked tentatively: "Teacher, in fact, you haven't made any major discoveries worth being happy about in the past ten years, haven't you?" ”

Gu Yunxuan sighed: "It is difficult for a good woman to cook without rice, just the limited historical data records, as well as the pamphlets left by the general, at best, they are all on paper, and it is not easy to completely understand the XV virus." Six years ago, that veteran cadre made a special call to me and talked about this incident, but I didn't make any breakthroughs, and I felt very ashamed. He also smiled and comforted me, saying that this matter is no less difficult than ascending to the sky, and that it is unrealistic to think that I can crack the secret of the XV virus in one moment, and told me not to be impatient and rash, and to try it slowly. He also said that the pamphlet given to me represents his personal behavior and is not an official attitude. I understand that the old cadres told me this because they wanted to reduce the pressure on me as much as possible, so that I could calm down and concentrate on scientific research without worrying about some miscellaneous trivial matters. In this way, if you can achieve something in the future, you can be regarded as making a great contribution to the country; Even if it doesn't work out, it won't be a burden on me...... A month later, the bad news came that the old cadre had died in the capital. The only thread I could hope to be able to communicate and consult on XV virus research was completely broken, and the hope was even slimmer, and the research experiments in this area came to an end, and this waste was a full six years. ”

Lin Han also sighed: "Teacher, it's not that you don't act, it's just that the conditions are too harsh. If you want to make a difference, you have to be able to do it, right? Almost already a legendary virus, with little information recorded, put on whom, is just as helpless. ”
