Qin Shou carefully planned the mine defense and drew figures on paper.

With virtual maps, the terrain of the southern mine has been clearly recorded for a long time, and the most suitable defensive formation can be designed based on the ready-made shape.

For old gamers, it is easy to set up defenses using game props based on the terrain.

Qin Shou was immersed in the design drawings and completed them as soon as possible. He could quickly start construction after taking down the mine.

Do things seriously and time passes quickly.

In the blink of an eye, three hours were almost dinner time. The research station used radio to contact Qin Shou, and Yu Shixiu asked him to go there quickly.

Qin Shouxin said that it was only two or three hours, why did he ask himself to go over? What can he find out at this time?

Yu Shixiu didn't say it clearly during the call, but just asked him to arrive at the scientific research station as soon as possible, which seemed very important.

Although I didn't want to be bombarded by Yu Shixiu's eardrums in a way that he dared not look down on him, what if something really happened?

Immediately drove a helicopter to the scientific research station and landed on the rooftop.

As soon as he got off the plane, Yu Shixiu brought people to greet him and pulled Qin Shou to walk directly inside.

"What's the situation?" Qin Shou asked hurriedly when he saw him so serious.

"We have done the simplest experiment, you'd better come and take a look!" Yu Shixiu said.

Qin Shou was full of doubts, thinking that there was something wrong with the experiment?

Follow the other party into the interior, put on protective clothing and came to the research room. Through the window, you can see a row of zombies tied to the test bed and unable to move.

The two zombies on the left are very quiet, unlike other zombies who keep twisting and trying to struggle, making a low roar.

"What do you want me to see?" Qin Shou asked curiously.

"Give it!" Yu Shixiu handed him a handwritten document.

Qin Shou took the document and opened it casually: "Experiment No. 1, male, 100% zombie-making degree, 100% virus density in the body, severe fracture of the left leg, damaged abdominal cavity, and lost a large number of internal organs... I said, what's the use of recording this kind of thing?"

"Science is rigorous, and of course the more complete the experimental materials, the better!" Yu Shixiu replied, "The key point is not this, you can see the rest."

"Focus?" Qin Shou turned his attention to the bottom, "I was vaccinated and observed. The external changes in the experiment were zero, and there was no sign of transformation. The density of the internal virus continued to decrease. The virus was cleared in 2 hours and 13 minutes, and no signs of survival were found. What's the problem?"

"Look back!"

Qin Shou turned a page: "Experiment No. 2, female, zombie degree, 100%, virus density in the body, severe neck damage, left eye loss... After being vaccinated, the external changes in the experiment were zero, and there was no sign of transformation. The internal virus density continued to decrease, and the virus was cleared in 2 hours and 7 minutes, and no signs of survival were found. Isn't this the same?"

"It's different. The virus clearance time of No. 1's experimental subject is 6 minutes longer than No. 2."

"..." Qin Shou was speechless, "What does it matter if the error is several minutes? Is this a very important thing?"

"No!" Yu Shixiu shook his head, "What's important is that after injecting the zombie virus vaccine, the virus in their bodies continues to die until they disappear. However, it did not transform from zombies into humans, but became a corpse that lost the virus."

"What's the difference between what I said?" Qin Shou spread his hands, "I told you that the vaccine is useless for zombies, and this conclusion has been confirmed. Congratulations on turning zombies into corpses. What are the benefits for us?"

"The experiment is meaningful!" Yu Shixiu said, "Although the zombies have not turned back into humans, at least the virus in the body has been completely eliminated and turned into normal corpses, and the immune virus should not be transformed again."

"Then what?"

"This means that vaccines can kill zombie viruses and work against zombies!"

"What's the use? A shot of a zombie can make it doom. I can kill it even if I shoot it with an arrow. Why don't I keep the vaccine for living people to use? I have to waste it on it?" Qin Shou shook his head.

"The most basic point is that killing zombies directly is simple. The corpse will pollute the environment and cannot inhibit the spread of the virus. Killing zombies with vaccines can eliminate the virus in the zombies and prevent it from polluting the environment!" Yu Shixiu replied seriously.

"I have other ways to deal with zombie corpses so that they cannot pollute the environment. Why waste vaccines?" Qin Shou shrugged.

He can decompose zombie corpses through the collection function, and there is no need to use vaccines.

Yu Shixiu said to Qin Shou: "Look carefully, although the experimental subjects No. 1 and No. 2 adopt injection methods, No. 1 is directly injected into the body, and No. 2 is injected into the mouth of the zombie. Since they can all take effect, it means that the injection method is not the focus, and the vaccine can enter the zombie through any method."

"What do you want to say?" Qin Shou looked at him in confusion.

"Have you ever thought that a large-scale treatment can be used with vaccines, and zombies can be eliminated without head-on combat!" Yu Shixiu said, "For example, setting up a moat, injecting vaccines into it. When the zombies enter the moat, water mixed with vaccines enters the body, they can remove the virus."

"Did you think about how many vaccines are needed to work in the moat? Will the effect be insufficient due to a large amount of clear water dilution?" Qin Shou asked back.

"These have been considered long ago and will be tested later!"

"No need to be so troublesome. Vaccines cannot turn zombies back into living people. Doing so is a waste of time and resources. To kill zombies quickly, there are many ways to do this."

Yu Shixiu thought for a while: "Before coming to Huajun, I saw fish and shrimps in Hanoi mutate, gnawing on similar species like zombies. Have you ever thought that if you indulge them, these fish and shrimps will continue to infect similar species, and sooner or later they will destroy the entire ecological environment. This is still the case in the river. If all marine organisms are infected, what kind of scene will it be? Vaccines can kill viruses and purify them. In the future, it may return clean oceans and rivers to humans. If they can eliminate zombies from all over the world, they will become a pure land, and humans will regain the four holy stars!"

"How many survivors survive in the world? Even if I keep making vaccines, I probably haven't eliminated the zombies of the Qinglong Kingdom until I die. Not to mention the entire Four Holy Stars, there are billions of people, at least fifty billion zombies! Besides, how big is the sea? It's not certain whether a river can work. The river water keeps flowing. Do I have to pour vaccines into it continuously? How many vaccines do I need? How can I not be diluted and successfully eliminate the virus in the water?"

"Maybe it sounds unrealistic. Science is about constantly exploring and turning the impossible into possibility!" Yu Shixiu said, "With vaccines, there is hope. If you don't try it, you will never know whether it will succeed or not. Maybe if you continue to study, you can find a way to successfully transform zombies back to humans!"

"If you have the intention to research, I may not be able to provide so many vaccines!" Qin Shou shrugged, "Of course, if you have the conditions, you will try to support you. Are there any other important discoveries?"

"Yes, look inside!" Yu Shixiu turned the document another page, "Before the experiment, I conducted a craniotomy on the experiments No. 1 and No. 2, and found a situation - the brain nerves of zombies are completely controlled by the virus, and all their behaviors are controlled by the virus. Most of the brain nerves die, but some are still alive, such as retinal nerves, connecting hearing, smell, etc. The retinal nerves are the weakest, indicating that zombies generally have poor vision, but the smell and auditory nerves are strengthened, several times that of normal humans!"

"I know all of these, and the information has been obtained in the battle." Qin Shou shrugged, "It's meaningless to me."

"If possible, I hope there are more experimental subjects, especially those variant types, to get more information."
Chapter completed!
