Zhang Yuntian has been thinking about this matter, he once said in the last final exam, but anyone who is excellent in the performance can get the opportunity to visit and study in the central DNA storage room, I heard that there is a perfect DNA comparable to Superman, just this point, just listening to it makes people excited.

"Let's go, the car is already downstairs, it just so happens that I am free this afternoon, I will take you to visit, and by the way, I will discuss with you about the G virus vaccine!"

A titan in the medical field like Yang Qingfeng, the whole federation can be compared with him, and he can be counted with one hand, so if in normal times, he says to discuss and discuss, in fact, he is humble, and he actually wants to point you out.

But now that he said this to Zhang Yuntian, the founder of the G virus, he was seeking truth from facts, and he was really just discussing and discussing.

The two said goodbye to Deng Qingshan, took Yang Qingfeng's special car, and returned directly to the headquarters of the Federal Medical Research Institute.

The institute is divided into two parts, above ground and underground, and the above-ground part is only a two-story building, mainly a rest room and office area for researchers, which looks very shabby and shabby.

The underground part is particularly magnificent, extending down to a depth of twelve floors, with the light room and the archives occupying more than half of the floors.

Under the personal leadership of Yang Qingfeng, the two came to a vaccine room on the negative third floor, looking at the trash cans full of instant noodles and fast food boxes, and the chairs arranged in a long row on one side, Yang Qingfeng and the medical staff around him seemed to have been studying here for many days, and even eating and living here.

"Come, Yuntian, look at this!"

Yang Qingfeng pointed to the screen, on which was the appearance of the G virus deity under a high-powered microscope, with teeth and claws, vaguely releasing something like electricity between them.

"According to research, these viruses are discharged to the brain of the dead host to achieve the purpose of controlling the movement of the corpse, and you see, the result of the antibody I developed will be injected into it!"

Immediately after the screen moved, some slightly smaller cells entered the side of the G virus, and slowly merged with it, and then the shell of the G virus began to gradually disintegrate, and the internal gene chains were scattered, breaking into pieces little by little.

"Success?" Zhang Yuntian looked at the screen excitedly, this antibody can effectively kill the G virus, does that mean that human beings are saved?

"Alas!" Yang Qingfeng sighed, "It's a shame to say, in fact, this is not a success, because the vaccine can produce antibodies against the G virus, but although the antibodies can kill the virus, they cannot replace the vaccine!" ”

Without Yang Qingfeng's too much explanation, Zhang Yuntian nodded, indeed, antibodies are equivalent to the antidote to the G virus, if a person is infected by zombies, as long as he is injected with antibodies without dying, then he can come back to life and return to normal, but if he is infected next time, he still needs to re-inject antibodies, so antibodies can only solve a temporary urgent need.

But in the end times, who can always act with a lot of antibodies? And if you are surrounded by zombies, whether you can have enough time to use antibodies is also a question.

The vaccine is different, once it is injected into the human body, it will stimulate the body's cells to produce antibodies against the virus, so that when the G virus invades, the cells will reactivate the antibody mechanism according to the memory to prevent humans from being infected, so the latter is the solution once and for all.

"Elder Yang, I have a DNA similar to a G virus vaccine, can you help me take a look?"

Zhang Yuntian took out a crystal carrier from his pocket, which contained the DNA of the necropsy vaccine.

"What? Did you make a vaccine yourself? Where? ”

Yang Qingfeng was a little surprised.

"I designed it myself in a rented house during the holidays, but there are still some loopholes, I need your help to take a look and adjust it!"

Zhang Yuntian can only make up nonsense, do you want to say that this thing was taken from the end of the world? G virus too?

Yang Qingfeng's eyes widened in disbelief, knowing that he had led a research team of five people and fought hard in this real room for a month before he could barely make antibodies, but he could not make a virus vaccine suitable for human vaccination.

And Zhang Yuntian was in a rental house, and he didn't even have real equipment, and he developed a vaccine alone? This can't be described as a genius at all, it's simply a genius.

Yang Qingfeng entered Zhang Yuntian's vaccine DNA into the computer, and after a while, the screen reappeared on the screen with the picture of normal human cells, and then the necropsy virus invaded, and the immune system immediately gave feedback and slowly produced antibodies.

In the second test, when the G virus invaded again, the immune system made antibodies again based on the memory and cleaned up the G virus.

"Cheng... It worked? How did you come up with the idea? ”

Yang Qingfeng looked at Zhang Yuntian in surprise, he couldn't believe that this was a vaccine DNA designed by a young man in his early twenties, and it was successful in one fell swoop without being verified by trial and error! The probability of this is much lower than winning the lottery.

Zhang Yuntian's face flushed, and he continued to make up: "I have actually been thinking about the DNA structure of the vaccine, and one night when I was sleeping, I had a dream, and when I woke up, I designed this DNA according to the dream, but I didn't expect it to be effective!" Merely... I feel that it still has zài shortcomings, and I can't tell where it is, Yang Lao is experienced and knowledgeable, so I would like to ask you to help take a look and improve it! ”

In fact, the development of vaccines requires continuous practice and attempts, and Yang Qingfeng's team and equipment are many times stronger than those in the last days, but after all, the time is short, and it takes only one month to develop antibodies, which is already very good.

It took several years to develop the apocalyptic corpse vaccine, and after several batches of scientists repeatedly conducted human experiments, it was only after such a semi-finished product, if Yang Qingfeng was given enough time, it would be impossible to develop the finished product.

Yang Qingfeng smiled, "Okay, you kid, not only have strength, but also good luck, I think you don't call me Yang Lao in the future, call me Lao Yang, I'm about to learn from you!" ”

Zhang Yuntian hurriedly waved his hand, "No, no, I'm purely a blind cat who has encountered a dead mouse, a problem of probability, a problem of probability!" ”

Yang Qingfeng smiled and was noncommittal, there are too few people like this who are young and promising, and who are not proud of their achievements.

He put the necadory vaccine into a virus simulator to run it, and it didn't take long for him to discover the problem.

Indeed, the behavior of the vaccinated people is too strange, their eyes are extremely empty, and their expressions are very relaxed, as if the whole person's soul has been suddenly drained away, and the only proof that they are still alive is the heartbeat, blood pressure and breathing displayed next to the system.
