99% survivability [unlimited]

After the first injection of vaccines for Xia Zhiyi and the others, Lu Zhongshu recruited another group of people for a meeting.The discussion is mainly about vaccines, and I am afraid that the vaccine production method will be confessed to some people.

The three of Xia Zhiyi were temporarily isolated after the vaccination, because the dose of the vaccine was small, and they didn't even have any uncomfortable reactions on their bodies.Of course, it is also possible that the vaccines given to them are different from Yi Yan's, and the resulting effects will also be biased.

In fact, the base is not without animals. Generally, when experiments are successful, animals are used for experiments first.But animals are different from humans, and the purpose of directly using them in human experiments is to speed up the progress and better convince the people at the base of the effect of the vaccine.

Even if many people think about the sequelae, it is worthwhile under the current circumstances.With a body that can resist zombie poison, even if you are accidentally caught and bitten when looking for supplies, you don't need to worry about it.

The survival rate of going out will undoubtedly be greatly improved.

Even if some people need to be sacrificed to obtain the vaccine, it has been successfully developed, and the improvement will depend on the efforts of others in the future.

But now that the vaccine has clearly been confirmed on Yi Yan, but he hasn't received the notification from the system, Su Mian has two guesses.

One is that the vaccine has sequelae and time limit, and the other is the coverage of the vaccine.

But since the task needs to be completed in just a few days, and they have no way of learning about the time limit of the sequelae so soon, Su Mian also feels that Lu Zhongshu can still be trusted on this point, so the point may be the coverage of the vaccine?

But does it really have anything to do with this mission?

"Actually, I was thinking that the task of [helping in the research of vaccines] has no way of saying whether it will be successful or not."

Yi Yan and Su Mian did not participate in this meeting. Although Yi Yan was freed in theory, he was actually guarded against him.He was also isolated in the room where he slept yesterday, Su Mian insisted on staying with him.

The two made some guesses about the mission. Su Mian shared her thoughts with Yi Yan, and was taken aback after hearing the other party's response: "But isn't Lu Zhongshu's mission to develop a vaccine?"

"He never said that his mission was to 'successfully develop a vaccine'. I guess his mission may be the same as ours, and he may have given the illusion of successful development."

They didn't get the exact information about Lu Zhongshu's mission. Similarly, Lu Zhongshu tended to guess about their mission.Except for the fact that the survival time of the main task is confessed to each other, neither side actually knows what the side task is.

It's just that Lu Zhongshu happened to be developing a vaccine, and they were very active in this matter, with the same goal, so they didn't ask more questions, and they defaulted to what they guessed.

Yi Yan's guess is not unreasonable, but the real point is actually not mentioned.

"But why is there no prompt in the system?"

"This may not be known until we survive to the end."

No matter how much entanglement continues, the problem cannot be solved. At least they all feel that they have done their best.In addition to the previous help, Su Mian donated her own blood, and Yi Yan became the No. 1 experiment.

These two points are the most intuitive and definite help.

In the evening, someone knocked on their door. It was Xia Zhiyi and others who were released, and said to Yi Yan in a low voice: "After discussion, they plan to develop a vaccine in batches."

What Xia Zhiyi concealed was that they were going to continue looking for new "victims".

Su Mian's blood only produced one vaccine, and the blood extracted from the victim's zombie did not have many vaccines.Now if you want to make a batch of vaccines, you need a lot of blood that meets the requirements.

It was also because Su Mian participated in this vaccine research and knew everything, so they said this to Yi Yan in front of Su Mian.

"When are you going to act?"

"Just tonight, this time, we plan to cheat first."

Today's vaccine test was not deliberately hidden, so most people in the base knew that the vaccine was successfully developed.

But they also know that researchers and people who are more useful to the base are the first to enjoy the right to be vaccinated. Ordinary people may have to wait for a long time.If other bases exchange materials for vaccines, and the number of vaccines is limited, they may not be able to hit them.

The more ordinary people are, the more afraid of death they are, and the higher their desire for vaccines.They are also the least likely to know how the vaccine is developed, so Xia Zhiyi said, use a lie.

Now his face no longer has the heaviness that he saw that day, like a messenger of justice, he can say "this is all for the better survival of human beings".

Survival of the fittest is a very realistic problem.

When Xia Zhiyi took Yi Yan away, he said to Su Mian, "Doctor Lu said that the next batch of vaccines is mainly for medical staff. As his assistant, you will definitely be able to get it."

Although Su Mian didn't need to be vaccinated, he still nodded.

Judging from Lu Zhongshu's test of Yi Yan's blood, Yi Yan has antibodies and is still human.This is different from Su Mian, Su Mian's blood is similar to that of a person who just turned into a zombie, so now it is certain that he should be a mutated zombie.

After nightfall, Su Mian lay down on the bed first, but couldn't fall asleep no matter what.

Yi Yan came back early, as if he didn't do anything.Knowing that Su Mian was curious, he even took the initiative to tell about the situation tonight.

In the last operation, they knocked people unconscious and took them to the laboratory, but this time they sent people to the laboratory by themselves.

Because Xia Zhiyi said to that person: "This is to secretly select a few weaker people to see if the reaction to the vaccine will be greater. We came to you quietly because we are afraid that other people will have opinions, so don't tell others."

To be honest, these people were the most afraid of death. Hearing what Xia Zhiyi said, he left with them in a nervous and excited mood.

Yi Yan's objection was that he was afraid that the person would not be easily deceived, so he could only use the same method as last time.But since the other party cooperates, of course he doesn't need to do anything.

"Tomorrow is the last day." Yi Yan just turned off the light when he heard Su Mian muttering beside him.

"Um"

"I always feel that the last day may not be so easy to spend." Su Mian looked at the gradually clear ceiling. There are always difficulties in the dungeon. It was originally difficult to develop a vaccine, but now it has succeeded.

Since the focus of the main mission is survival, the difficulty should also be in this place.

Don't look at Su Mian as if she doesn't have to worry about surviving whether she is on the side of zombies or on the side of humans, but no one can guarantee that there will be no accidents.

"Sleep, I'll find out what's going on tomorrow."

This sentence is right, if there is something, you will know it tomorrow?Su Mian obediently closed her eyes, letting go of her consciousness.

【Remaining time: 24 hours】

The weather was still extremely sunny. After waking up, Su Mian and Yi Yan came to the laboratory together.

Lu Zhongshu seemed to have stayed up all night, and had been extracting blood from new zombies with the two researchers, and making new vaccines in batches.

He also had the same idea as Su Mian, thinking about increasing the number of vaccines as much as possible on the last day.

"It's the last day, let's do more." When he was having breakfast, he smiled and said to Su Mian.

"In short, the main mission of our survival must be completed, and if the progress of the mission is about the same, there is a high probability that we will meet again in the next instance."

Lu Zhongshu seemed to be looking forward to this, and wanted to make a secret sign with Su Mian.

"But I think, even if I meet again in a new dungeon, I should be able to recognize it quickly." He seems to be very confident in himself, but this is not necessarily just bragging.

Although Su Mian has a different face in each dungeon, many places are actually similar.Every body he possessed was formed on the basis of his original body.

Whether it was the person who helped him in this dungeon, Su Mian felt that it was not good for the other party to keep talking, so she replied, "Then wait until the next dungeon."

He meant to say that we can only know if we will meet in the next dungeon, but in Lu Zhongshu's view, this sentence undoubtedly got a response, and it is natural that Su Mian is also looking forward to meeting him again.

"In order not to make people suspicious, I will tell them later that I have given you the first shot of the vaccine." His voice unconsciously softened.

Su Mian nodded, the food in her hand was finally finished.

Lu Zhongshu returned to the workbench again, and Su Mian, who didn't need any more help, sat with Yi Yan, who also had nothing to do.

"Are you looking forward to meeting him in the next instance?" Yi Yan asked suddenly.

"It doesn't feel like it. It depends on the arrangement of the system." Su Mian thought for a while. In fact, it might be really necessary for him in this Lu Zhongshu, but it's not sure when it comes to the next dungeon.

"Then do you want to go to the next instance with me?"

Su Mian turned her head and looked into Yi Yan's eyes.Lu Zhongshu once asked if they came together from the previous dungeon, Su Mian's answer was "I don't know".

He hasn't been in contact with other players for a long time in each dungeon, and he has never carefully analyzed their character.Because in his opinion, the personalities of the people that each dungeon comes into contact with are completely different.

Because he understands his own particularity, he is more willing to believe that every dungeon encounters a different person.

But if he thought about it carefully, he seemed to be able to see some familiar shadows from Yi Yan's body.

"you...."

"It's bad! The door of the base has been opened, and the zombies from outside are pouring in!!" Someone shouted loudly in the building, breaking the supposedly comfortable atmosphere.

All of a sudden, the surroundings were full of commotion, everyone rushed to the window to see the situation, Su Mian and Yi Yan were no exception.

They are in a tall building, and they can see the situation of the base gate at a glance.It seems that it has become a paradise for zombies.

Without the wall that separates the inside from the outside, the zombies outside followed the scent to look for their prey inside.
