According to Sun Aiguo's introduction, the mystery of the research center has also been unveiled little by little. The research center is an abandoned strategic material reserve site, which was established during World War II. In fact, the same is true of the original body.

During World War II, it was a natural cave. The mountain people dug roads and built a shelter according to the shape of the cave, where they stored some necessary daily necessities. After the war, the government took over the site and built a research center without much change in appearance. It is indeed claimed that the geological structure here is not stable enough, and because the mountaineers have no scientific planning and indiscriminate excavation, this place is already dangerous, and there is a danger of collapse or landslide at any time.

The villagers are very realistic, and when they hear the government's righteous explanation, they slowly don't dare to get too close to here. In this way, an isolated research center was built. And for better protection, the government has also designated the area as a national protection base, and a lot of wild animals are stocked in the mountains. The houses they saw halfway up the mountain were all left behind by some respected local villagers a long time ago. The old people did not want to leave and continued to live, but the younger generation had already moved away.

Biochemical biology research has many limitations in the world. Huaguo is a country that is very concerned about its national image and has to accept these restrictions. But there are some studies that you can't do if you don't want to. Just like nuclear weapons, one is needed for economic development, and the other is for deterrence. If China had not developed nuclear weapons in those years, it would not be known what its status is in the world today.

So this research center can only be secretive and secretive. The first generation of researchers were patriots who were passionate about scientific research. They are preoccupied with academic research. Moreover, the people of that era did not have too many requirements for the state and individuals. In addition, the country has found many people who have been orphaned by the war. Grew up in the research center. Those who have the ability will take over scientific research, and those who are not capable will do the work of preservation and hygiene. Anyway, I can't do without it.

In this way, the history of Huaguo for decades, and the history of this research center for decades, it is said that there are 4 or 5 generations. Some people never leave the center in their entire lives, from birth to death, and have never even seen the sun, moon, or stars.

Sun Aiguo is already in his 70s, and they are only the successors of the second generation, and they are also orphans collected by Huaguo at that time. They won't leave here except for academic exchanges.

And here is the research. Varied. Only what you can't think of. It is said that there are hundreds of projects, and these have certain results. Those who failed were not counted. There are all kinds of mythical beasts, mythical animals, extinct animals, genetic mutations or genetically heterozygous animals.

Originally, these subjects were strictly controlled. And it's also multifaceted control. For example, when it is not necessary, the test subjects are anesthetized. And the experimental cabins are all the highest level of surveillance. It's a tyrannosaurus. You can't easily break out of the door, let alone be injected with general anesthesia? But all that changed when the end came.

When the apocalypse broke out, they didn't feel anything in the research center. It's just that some people fainted inexplicably. And their research is done day and night. As a result, some of the test subjects escaped. Some of the staff in the monitoring room also fainted. Therefore, it is not possible to control the situation in the first place, shoot the fleeing test subjects, or activate defensive measures and close the department's laboratory.

You can imagine how chaotic it was. And when those who fainted woke up, the situation was even more dire. Some of them have activated abilities, and more of them have become zombies. Because although it is a body specially cultivated by the state, it lacks exercise and sunshine, and its physical fitness cannot be compared with people outside. So they mutate at a higher rate than the outside world.

Troops were also stationed here. By daylight the next day, the army and the remaining researchers had stabilized. Start a gradual clean-up layer by layer, zone by zone. And for those who faint or are injured, isolation measures are also applied.

In the first few days, this practice still worked. But the good times didn't last long, especially after a rain. Of course, they didn't know it was raining outside. They only noticed that the test subject, which was otherwise manageable, had suddenly changed. Some suddenly become larger, some become irritable and bloodthirsty, and some come back from the dead.

And these test subjects, after the anesthetic is no longer effective and the defenses are destroyed, they are not humanly controllable. So this time it became them who were cleaned up. Originally, there were still a few hundred people, almost a thousand people, but by the time they were chased to this control room, there were only 22 left.

The entire research center has only three floors, but it does cover an area of nearly 10,000 square meters. This is mainly due to the fact that some of the subjects are quite large. And they also divide it into living areas, education areas, etc. But now, all they have at their disposal is a meagre 50 square meters.

And this central control room can open every door of the research center, and you can also view every corner. However, they damaged a lot of equipment during the previous cleanup, even their mains power supply. So when they entered the control room, a lot of the place was a black screen. And in order to save power, they can only turn off unnecessary equipment. And so when they came in at the end of the season, they didn't notice.

The doors of the three entrances cannot be opened, because if these out-of-control test subjects escape, it will be the entire country of China that suffers. It's the subject's madness, and they know it.

"Do you have any test subjects of snakes?" A person couldn't wait to ask out. The biggest threat they encountered along the way was the mutant snake.

"Snakes? Of course. ”

"How long are your test subjects?" This time it's the end of the season asking.

"Well, the biggest one should be around 30 meters. Right? Sun Aiguo turned around and asked a young man, he was not in charge of the project, but this man was one of the assistants to the person in charge of the project.

"There are many species of reptiles, among which snakes are one. There are 4 in total, two males and two females. The longest one is 31.4 meters and the shortest one is 17.9 meters. ”

The longest recorded snake in the world is less than 12 meters. They didn't ask why the snakes here were so long. If it had been before, they might have found it difficult to accept. But after seeing the end of the world and the mutant snake, they thought that there was a dinosaur standing opposite, and they were not surprised. (To be continued......)

PS: It's a holiday tomorrow, and I'm going to take Ben Ben back to my grandmother's house, and I'm temporarily in a state of no network.
