99% survivability [unlimited]

Seeing Su Mian and Yi Yan come in, Lu Zhongshu slowly stood up from the laboratory table. "Now I have good news and bad news, which one do you want to hear first?"

Neither Su Mian nor Yi Yan replied. They didn't think that the vaccine development had failed, so the good news should undoubtedly be this. What they needed to know was actually only bad news.

Seeing that they didn't respond, Lu Zhongshu continued automatically: "Well, the good news is that the vaccine has been successfully developed, and you should be able to guess the bad news."

Yi Yan nodded cooperatively, while Su Mian reacted after thinking about it.

The vaccine has been successfully researched—but the broadcast of the mission did not give them any hint that the mission was successful.

"I think, maybe the vaccine will not be considered successful until the vaccine is officially effective. It seems that I was right to prolong the time. Sure enough, the dungeon will become more and more difficult to deal with."

Lu Zhongshu reached out and put his hand on the back of his neck, loosening the sour neck that had been caused by bowing his head for too long.

"After that, I have to find someone who was bitten by a zombie after voluntary vaccination, tsk."

It's not difficult to zombify people, but the people who test the vaccine had better do it voluntarily.Lu Zhongshu has absolute confidence in the vaccine he developed, but human psychology is not willing to be the first guinea pig.

For others, there is no certainty that the vaccine will be successful.If you force it, it will create hatred in that person. If it succeeds, that person who maintains reason and hatred will not know what to do.

But I have to say that finding such a person will be easier than finding someone who voluntarily turns into a zombie.

Yi Yan walked forward to the side of the experiment table, glanced at the things on the table and asked, "How many vaccines are there now?"

"Two, one uses Su Mian's blood, and the other uses his." Lu Zhongshu gestured to the zombie who was still tied to the chair. All gone.

"In terms of effect, of course the previous one is better."

"I can inject one, but I want Su Mian's blood." Yi Yan said, not negotiating conditions with Lu Zhongshu, but making a decision.

"Okay." Of course Lu Zhongshu would not refuse the mouse that was sent up, even if he and Yi Yan had a disagreement, he would not feel sorry for a vaccine.

Besides, with Yi Yan's statement, there is no fear that no one will try another vaccine.

"Doctor Lu, everyone is waiting for you in the meeting room." Soon a researcher came in from outside and said to Lu Zhong.

"Okay, you guys go with me."

The three of them went upstairs to the conference room together. This time, there was no noisy feeling like last time, but a piece of silence.

Everyone present looked at Lu Zhongshu with complicated eyes, and they were more surprised that he had actually developed a vaccine.In fact, it's hard to judge whether they knew that Lu Zhongshu was experimenting with living people. Su Mian felt that not everyone knew about it.

The meeting this time was very brief. It was Lu Zhongshu who announced the successful development of the vaccine and will test the results this afternoon.The reason why he asked Yi Yan to come with him was to tell these people that he had already found someone who would volunteer to be a test subject.

The same news was also passed on to Xia Zhiyi, just as Lu Zhongshu thought, when they heard the news that Yi Yan offered to be vaccinated first, many people began to move around.

But they still had reservations, hoping to see the results of Yi Yan's vaccination first.

The location of the experiment was set on the first floor of the laboratory building. Yi Yan sat on the new chair to prevent him from turning into a zombie. Xia Zhiyi and other combat forces stood in the innermost circle to deal with emergencies. The researchers stood on the outer floor.

There were whispering voices all around, and among them there was no lack of people who doubted whether Lu Zhongshu's research was really successful, and most of their eyes were sympathy and admiration for Yi Yan.

The two researchers involved in the research of the vaccine were also very nervous. After all, success in theory is not the same as success in practice.

Lu Zhongshu was standing in the middle, and it was Su Mian who was in charge of delivering things for him.The two of them can be said to be the calmest among the people present. Su Mian believed that Lu Zhongshu would make the first experimental subject succeed, so he would definitely not let Yi Yan have an accident.

Otherwise, if he failed, not only would he not be able to complete the mission, but the trust of the base people would drop significantly, and they would no longer listen to him.Yi Yan probably thought so too, so he offered to be the first one.

The needle took out the liquid in the vial, and Lu Zhongshu sterilized the place where Yi Yan was going to inject the vaccine, and then slowly injected the reddish vaccine liquid into Yi Yan's body.

It seems like a simple action, but the only thing that makes the surrounding quiet is the sound of careful breathing.

Yi Yan tensed his muscles for a moment, and his expression changed.Those medical researchers took a step back subconsciously, but they didn't make any judgments immediately, but continued to watch Yi Yan's changes.

Because they all know that vaccines carry some viruses, and they will definitely react after being injected into the human body.

Apart from the tense muscles in his whole body, Yi Yan showed no signs of losing control. Lu Zhongshu started talking to him, asking him how his body felt, and also confirming whether he lost consciousness.

"It's going to be a little uncomfortable, but it doesn't make the brain spin out of control."

"The vaccine is not considered mild, and I am afraid it will require physical fitness."

"After that period of time, there is no other feeling."

Yi Yan responded to Lu Zhongshu's question sentence by sentence. He lowered his head and looked at the place where the vaccine was injected. The skin there was temporarily turned pale, but now it is slowly recovering.

The people around have also discovered this, which shows that the vaccine is really effective. They finally put away the worry in their eyes with joy. No matter what, as long as the vaccine is effective, they have hope.

According to Yi Yan's words, the vaccine is not suitable for one-time injection. For ordinary people, it may be safer to inject in batches.

After waiting for half an hour, Yi Yan's expression returned to normal, but for safety's sake, he should have little chance to leave the chair today.

He was sent to the laboratory upstairs, under the care of Xia Zhiyi and the others.Except for some special time, Yi Yan will stay in this chair today.

Even though they had already heard his answer, Xia Zhiyi and the others stood in front of Yi Yan, they were still carefully asking him how he felt.Yi Yan will respond, and describe it in detail as much as possible, so that Xia Zhiyi and the others who are destined to be the first batch of vaccination targets will be prepared.

The remaining vaccine was taken away by Lu Zhongshu to reduce the dose. He also knew that not everyone has Yi Yan's physique, and the first experimental subject was Yi Yan, which really avoided some accidents.

Lu Zhongshu made three doses of the vaccine, that is to say, the next person needs to be injected with the vaccine three times, and the interval between them needs to be calculated.

Su Mian stayed by Yi Yan's side all the time, and didn't go back to that room to sleep at night, but made a bed on the floor.Compared to Xia Zhiyi and the others who had to take turns keeping vigil to watch over Yi Yan, Su Mian could still sleep until dawn.

Although the ground was a bit hard, but thinking that Yi Yan could only sit and sleep, he felt much better.What's more, when he first came to this dungeon, he did the same thing about laying the floor.

[Remaining time: two days]

The curtains in the laboratory are not ventilated. After a rainy day, the sky turns sunny again, so the dazzling sunlight falls on the eyelids, which makes people lose the desire to continue to sleep.

Su Mian opened her eyes and saw that Yi Yan was no longer on the chair. He was standing with Lu Zhongshu Xia Zhiyi and the others, talking in a soft voice.

He was the only one who was still sleeping at this time, and these people deliberately lowered their voices so as not to disturb him.As for why he didn't leave, he probably wanted to wait for him to wake up.

Su Mian sat up slowly. Standing up from the ground was more difficult than getting up from the bed. Feeling that his head was still a little confused, he sat for a while longer.

The sunshine was on the side, making him narrow his eyes slightly, he yawned a little, and saw that Yi Yan had already walked in front of him and stretched out his hand, intending to pull him up.

Su Mian stood up following his strength, because he hadn't taken off anything yesterday after laying on the floor, and felt that the clothes on his body were messed up as soon as he pulled them.Yi Yan stretched out his hand to help him straighten out the folds of his clothes, and asked him to wash his face first to wake up.

After a day, Yi Yan, who did not show any abnormalities, was finally allowed to act freely, but facing the re-emerged sun, what he was about to do depended on whether the vaccine had any effect.

The signal that the task is completed still hasn't come, the vaccine is no problem, I'm afraid it won't be until Yi Yan is bitten by a zombie and he's all right again.

It was another mighty army, and this time there were also some excited base residents gathered around.

The purpose this time is that if Yi Yan is to be bitten, there is no need for the zombies to show mercy. Xia Zhiyi and others offered to go out with Yi Yan. In order to achieve the best results, Yi Yan did not choose to be caught by the zombies, but Sacrifice yourself to be bitten by a zombie.

Then, he exploded the zombie's head.

After being bitten by the zombies, he couldn't go back to the base directly, but everyone knew the horror of the spread of the zombie virus. After a period of time, he didn't see any abnormalities in Yi Yan, so he was asked to go back to the gate of the base and sit down again. Get on that chair.

But in fact, the effect of the vaccine is already obvious, and it can definitely prevent the zombie toxin from spreading in the body.

There were already cheers behind her, and a little weeping in her ears, and Su Mian turned her head to realize that it was the two researchers.

If they still can't produce results after forcibly turning people into zombies, they can't live with their conscience. Now that the vaccine is successful, no one will reprimand them on this point.

But according to what Lu Zhongshu said, if the current technology still needs to rely on fresh blood to develop a vaccine, there will definitely be sacrifices in the future.

Lu Zhongshu drew Yi Yan's blood, and after a while announced that Yi Yan's body had developed absolute resistance to the zombie virus.Afterwards, led by Xia Zhiyi, three people were willing to try the vaccine whose efficacy was reduced and needed to be administered in batches.

Everything seemed to be going in a good direction, but for Su Mian and the others, that was not the case.

Because the system broadcast of the successful development of the vaccine still did not appear.
