99% survivability [unlimited]

Sacrifice is required to achieve results.

Lu Zhongshu was able to persuade the aborigines of this dungeon to implement such a plan, which shows that he still grasped the psychology of these people in the current environment, and should also think about this issue from their perspective.

In addition to the guarantee that "a vaccine will be developed within three days", some pressure should have been exerted.It's just that Su Mian was not involved in this plan.

In the current situation, it's not just a unilateral decision made by their players, but also the path chosen by the people in this dungeon.When it comes to survival, the responses that humans can make are always unexpected.

Su Mian is not qualified to judge this kind of decision, when he was in the crowd, he became one of them.Besides, he really didn't arouse too much sympathy.

The person tied to the chair became more and more quiet, and then he even twitched occasionally, which was not considered a struggle, and only when he moved occasionally could people feel that he was still alive.

Su Mian felt that Lu Zhongshu had almost drained all the blood from this person, and if they were placed in the order in which they were drawn, one could find that the color of the blood was gradually getting darker.However, because of the extreme timing of zombification, it is not very obvious.

After finishing this matter, Su Mian was free. He stood at a distance and watched Lu Zhongshu and the two researchers study the freshly drawn blood.

The two researchers who analyzed the blood quickly showed joyful expressions on their faces. Obviously, this fresh blood is very useful.This kind of research continued for another day. In the afternoon, Lu Zhongshu took some blood again, and did not call it a day until evening.

"Thank you." After the research came to an end, the two researchers packed their things and went back to rest.

"I can finally sleep well today."

"Yeah, it's finally going to succeed." They said as they walked out, seeming to have forgotten that the person who was forcibly turned into a zombie had a relaxed expression on his face.

Maybe it's because they don't have the slightest sense of guilt because they didn't move their hands, or maybe it's because the research is very successful, and they can finally feel at ease.

"Are you surprised by their attitude?" After the two men left and closed the door, Lu Zhongshu asked Su Mian who was looking at the door.

"No." Su Mian shook her head.

"I said that I will do it myself, and they are not responsible for this matter." Whether Su Mian was telling the truth or a lie, Lu Zhongshu also explained.

In fact, I can really understand it. It's more about seeing their attitude towards this kind of thing from this kind of dialogue.They could not evade Su Mian from saying such things, obviously they put Su Mian, who was here to help, into the same camp.

Su Mian just won't take the initiative to do it, but she won't really stop them from doing it.On the contrary, it was Lu Zhongshu and Yi Yan who kept it from him, as if they were trying to reduce his guilt.

"If you hurry, the vaccine will be successfully developed tomorrow." Lu Zhongshu took off his gloves and went to the sink to wash his hands clean.

The vaccine was developed within three days because Lu Zhongshu said the time was too long. After all, he also needs a certain buffer time. It is not a good thing to complete the task when the date is approaching.

Extending the time can also prevent accidents and provide opportunities for adjustment.

"However..." Lu Zhongshu looked at Su Mian with a different emotion in his expression. "His blood is not as effective as yours."

What Su Mian has been thinking about, the other party finally gave him the answer.He didn't think it was Yi Yan who took the initiative to say that the blood was his, and he was prepared to be guessed by Lu Zhongshu.

"Since my blood is useful, why...?"

"I have already said that toxins and blood extracted from zombies that have not turned into zombies are needed to develop a vaccine, but a vaccine has been developed without such zombies. What do you think other people in the base will think?"

"They will think that I secretly found someone to do the experiment, and maybe they will come to me to question. Instead of this, it is better to make it clear to them directly and let them go to these 'not helpful to the base. Those who have made a contribution to the vaccine."

Except for the medical staff, the men in the base have to go outside to find supplies, otherwise there will not be much supplies in the base.

But in such a large base, there will always be "very few" who can no longer produce labor force, and they will also be eliminated by the end of the world.Out of humanitarianism, these people can still live in this base.

The people who had accidents while searching for supplies all died outside the base, and these people didn't come back from the battlefield, so it can be said that they really didn't make any contribution at all.

In fact, most people in the base would be dissatisfied with this kind of people, but there are many reasons for leaving these people in the end.

Lu Zhongshu persuaded them to attack these people secretly, and became a victim of mankind's march towards a better future.He was not someone who would stay in this world forever, so of course Lu Zhongshu would not care what people in this world would think of him in the end.

"And with the means I have now, every vaccine needs some blood as a primer. If only your blood is used, you may be sucked dry, right? I understand the reason why you hid yourself slowly before. If you let this The other people in the base know that you have been bitten by zombies, and I'm afraid they will treat you as an alien."

"So whether it's to help you hide the secret, or to take this step, you need other victims."

As long as everything starts, the second and third will become natural afterward.

"You can stay with me from now on. I have already prepared the room for you."

Lu Zhongshu's previous words were a little threatening and telling Su Mian that it is safest to stay in this laboratory.

"Then I'll go and talk to Yi Yan?" Su Mian didn't refuse this time, but just changed his place of residence. When the vaccine is successfully developed tomorrow, he only has two days to survive.

As long as there are no new tasks coming out, the two days should pass quickly.

"No, I've already told him about it." When Lu Zhongshu said this, he subtly assumed a superior victorious attitude, as if he had finally achieved something.

But even if he said that, Su Mian felt that Yi Yan was not someone who would not talk to him after agreeing to Lu Zhongshu, and subconsciously felt that there was something wrong with what Lu Zhongshu said.

"Let's go, I'll take you to your room." Lu Zhongshu had already arranged everything in the laboratory. He didn't intend to kill the zombified person. He should continue to study tomorrow.

The two opened the door of the experiment and went out, but saw Yi Yan standing outside the door.He was standing by the window, leaning against the wall and looking out of the window, when he saw the two people coming out, he straightened up.

"Why are you here?" After a moment of surprise, Lu Zhongshu frowned.

"I have an obligation to protect the safety of this building, isn't it normal to come here?" He walked to Su Mian's side and continued, "Su Mian and I have walked all the way in this dungeon, of course we have to be together, I think He doesn't want to be separated from me either."

Now Su Mian believed that Lu Zhongshu must have told Yi Yan about this in advance, and Yi Yan agreed, but he didn't mean to let him live here alone.

After saying this, he looked into Su Mian's eyes and asked softly, "Is that right?"

The sentence "I don't want to leave" is a bit strange no matter how you look at it, Su Mian directly skipped this question, and turned her head to ask Lu Zhongshu with a not-so-good face, "Can he come and live with us?"

Undoubtedly, he asked this question because he hoped that Yi Yan would stay. Although it was strange, Yi Yan gave him a much stronger sense of security than Lu Zhongshu.

He asked this question, and Lu Zhongshu couldn't say no.

"We lived together a few days ago, just ask Dr. Lu to arrange a room for us."

This time, the subtle feeling of being a winner appeared in Yi Yan's body.The momentary sense of peace between the two of them yesterday has completely dissipated, and it seems that they have returned to the sense of mutual exclusion when they first met.

But in the end Lu Zhongshu arranged a room for them, but obviously, it was not the "prepared room for you" that Lu Zhongshu said earlier.

It wasn't messy, but it didn't look like it had been carefully tidied up inside.There are two beds inside, which are remodeled hospital beds. There is no bathroom inside, so you need to go to the bathroom outside.

It can be said that the environment is much worse than the place where I lived before.

"Good night, I hope I can bring you good news tomorrow." After Lu Zhongshu finished speaking, he looked over Yi Yan before closing the door for them.

Su Mian's mood didn't get any better because of his words, and then she and Yi Yan went to the bathroom outside to wash their mouths and face, and when they returned to the room, they chose the inner bed.

Yi Yan was not affected by such an environment, and he said something to Su Mian when he was still sitting on the bed: "When I came, I heard that Dr. Lu, who was living independently, moved into a double room."

"..."

He felt that Yi Yan seemed to be in a good mood when he said this, but he didn't understand.

The modified hospital bed is rather high. When going up, Su Mian just sits on it without turning around to let her knees go up first. It is more convenient. She still takes off her outer pants when she sleeps, and the T-shirt that fits will be used when doing this action. Show your waistline.

When he climbed into bed and lay down and looked at Yi Yan, he seemed to feel that the other party seemed to be in a really good mood.

"Go to bed first, I'll turn off the light."

"Okay." Su Mian nodded and lay down. In summer, she doesn't need to cover her with a lot of quilts. It's enough to cover her lower abdomen to prevent colds.He watched Yi Yan turn off the light and closed his eyes.

[Remaining time: three days]

Like a countdown to three two one, the system's announcement brought Su Mian a little excitement.In the morning, he still went to help the laboratory. Although he didn't have anything to do, Lu Zhongshu didn't mean to let him leave.

He didn't let Su Mian go out for lunch until noon.

Yi Yan didn't leave either, he had lunch with Su Mian, and then walked towards the laboratory, and saw two excited researchers coming out of it.

"Successful! We can finally have some confidence!"

There were even some tears on their faces, and then they went out to call all the personnel for a meeting.

This obviously means that the vaccine has been successfully developed. Su Mian and Yi Yan stepped into the laboratory together, and saw Lu Zhongshu sitting in front of the laboratory table, with two vials in front of him.

Unlike those two experimenters, there was not much excitement on his face.
