99% survivability [unlimited]

It takes a lot of time to build a base, but it only takes an instant to break through.

Obviously, the gate of the base has been completely occupied. Countless zombies poured in from the gate. They attacked the people fleeing at the gate indiscriminately. No one could close the gate again.

This led to more and more zombies entering the base, and the number could not be solved immediately.The siren of the base had sounded, and everyone in the building quickly closed the door and drew the curtains.

The people in the exercise base to prevent the zombies from breaking out have still done it. At this time, the best thing to do is to hide in the building and not go out.As long as the zombies can't see the target, they won't gather here, and they are safe for the time being.

But the most urgent thing is to find a way to close the opened door, so as to have a chance to clear all the zombies in the base.

"What the hell is going on, how could the gate of the base be opened?!"

"What are the people guarding the gate doing?! Why were the zombies brought in!"

In the midst of panic, someone questioned with an angry and broken voice.The opening of the gate of the base would definitely not be done by unconscious zombies, it could only be man-made.

This undoubtedly means that everyone is going to die, but now that the vaccine has been successfully developed, who would be so overwhelmed?

"Yes... did any of them know about that?"

Someone asked in a low voice, with fear on his face.

Su Mian didn't know that just yesterday when the vaccine was approved as a success, Lu Zhongshu had a meeting with some people, and a complete list of "victims" was already listed.

Because Lu Zhongshu was the "murderer", they didn't even hesitate to name some names.Just like Xia Zhiyi, some people were classified as "useless".

These people were unilaterally sentenced to death by them, and death is only a matter of time.

It is only this group of people who will become obsessed when they know they must die, and do such things with the mentality of 'why should I sacrifice, if I am going to die, then die together'.

Lu Zhongshu obviously thought of this too. He had no intention of continuing to make vaccines. He stood by the window and raised a corner of the curtain to look at the situation outside the building, and then looked at Yi Yan with a gloomy expression.

"What happened yesterday?"

"Xia Zhiyi and the others were aboveboard when they brought people here, and the last time they brought people here, they disappeared without explanation. Even the weak will have groups. Some of them disappeared for no reason. You will think they can't guess what's going on. ?"

Today's living environment is so small, those who don't make much contribution to the base are living in a cautious way.

You can make the situation worse. For example, when they are collecting supplies, someone will say: "Why does he have the face to take supplies?"

"If I were him, I would die outside without causing trouble to others."

"So much material wasted in vain."

From a peaceful life to the end of the world, they have become mouse-like existences. Their hearts have already squeezed a lot of negative emotions, which is a stage that will explode at any time.

If they could have the awareness of "self-sacrifice", they wouldn't have to survive even lying on their stomachs.

But until now, the development of a vaccine is tantamount to breaking their last straw.It's really not surprising if they do these things.

The point is no longer how they knew about it.

It was also because Lu Zhongshu hadn't given any advice to Xia Zhiyi and the others before, thinking that it was the last few days and all his attention was on developing the vaccine.

And Yi Yan is not the leader, and probably won't dictate what other people do.

Who would have known that on this last day of survival, new side missions appeared.Guarding this base within a day, the system is really giving them a problem.

Lu Zhongshu didn't care about the life and death of other people in the base, but obviously he should also have the same task as Su Mian and the others, to protect the base.

He didn't ask Yi Yan any more. It's more important to do the task than to pursue the responsibility after the matter has come to this point.

Su Mian saw that Lu Zhongshu took off his long white coat and rolled up his sleeves, obviously he didn't intend to stay in the laboratory building any longer.

"Walk?"

Yi Yan beside him nodded, at least at this moment he had reached a consensus with Lu Zhongshu.Since the base is to be defended, the first thing to do is to find a way to close the gate of the base.

The only thing that makes Lu Zhongshu regret now is probably that he didn't expect to give himself a vaccine made with Su Mian's blood, otherwise he would be able to let go of his hands and feet better.

He thought about it, and looked at Su Mian: "In your current state, will zombies attack you?"

Su Mian shook her head honestly: "No, they seem to regard me as the same kind."

"That's good."

Su Mian obviously doesn't have much combat power, if the zombies won't attack him, then he can take him to participate in the next action with peace of mind.

Staying in the laboratory is called hiding, not "guarding".

The door on the first floor was tightly blocked, and medical researchers who usually do research and don't lift heavy objects have started to pile up some desks at the door.

In this way, people outside cannot come in, and people inside cannot get out.

It was obviously impossible for the three of them to leave the building and go to the first floor, so they had to jump from the second floor.He first gave some instructions to the two researchers, and then brought Su Mian and Yi Yan to the side of the second floor where the zombies hadn't come yet.

After all, Lu Zhongshu has several dungeon experience, and his physique is not bad, so it is not difficult for him to jump from the second floor.

Like Yi Yan, he has experience in jumping from high places.

Yi Yan landed almost at the same time as him, then turned around and stretched out his hand to Su Mian above.Without the slightest hesitation, Su Mian jumped in the direction of Yi Yan.

A series of actions were carried out quickly, and when Lu Zhongshu realized that he wanted to pick up Su Mian, Su Mian had already fallen into Yi Yan's arms.

Lu Zhongshu couldn't help but take another look at Yi Yan. Even though Su Mian looked light, his weight was still there. Yi Yan caught Su Mian very easily, which proved his physical strength.

Of course, Lu Zhongshu may not know that Su Mian actually has a "wish".But this also cannot be said, Yi Yan does not have such a good physique.

Yi Yan put Su Mian on the ground, besides the gun, he and Lu Zhongshu each took a steel pipe.The most indispensable thing in the base is weapons, even in the laboratory building there are many.

Just in case, even Su Mian took one, and then he realized that the weight of the steel pipe was not something he could swing at will...

Lu Zhongshu is more familiar with the environment of the base, so he can take the path that avoids zombies as much as possible.It was inevitable to encounter a few zombies on the road, and they were turned into after the residents in the base were infected.

As the only person in the base who is confirmed to have an absolute antibody against zombies, Yi Yan is at the forefront and takes the lead.Gunshots have been heard not far away, and it is obvious that other people with bases have already launched operations.

When Su Mian and the others arrived at the gate of the base, they saw Xia Zhiyi and the others fighting with the zombies.

They also wanted to close the door of the base, but there were too many zombies in front of them, and they had almost no place to hide. As soon as they appeared, they became the target of being chased and attacked by the zombies.

It is not a wise choice to use a gun at this time, because the loud noise will only attract more zombies, but if they don't use guns, they are no match for so many zombies.

These people don't have such vigorous skills as Yi Yan, and the steel rods in their hands are almost bent by them. The worst thing is that the number of zombies that one person will deal with is several times that of them!

One of them was holding the steel pipe against the zombie's teeth, but behind him, another zombie was about to pounce on him.The other people couldn't help him at all, seeing that he was about to be bitten——

"Bang—" the gun in Lu Zhongshu's hand fired bullets without hesitation. While causing the zombie to fall, the loud sound also attracted the attention of the zombies.

They turned their heads in unison, and then froze their movements, as if they had no ability to attack.The other people who were fighting hard had time to breathe, and quickly swung the weapons in their hands, blowing the heads of the zombies in front of them.

The frozen zombies finally started to move again, slowly walking towards Su Mian.Then there was the roar of the truck, and someone successfully drove to the car to support.

The truck came all the way and crushed a few zombies, which relieved their pressure even more.But in the end, this is just a temporary solution, not the root cause. The number of zombies has not decreased, and even seems to be increasing.

Su Mian and Yi Yan ran to the parked truck, and he was picked up and pushed onto the truck by the other party. The others also came here one after another and jumped onto the truck.

The truck has a height that zombies cannot climb, so it is safe for the time being.

Looking at the faces in front of him, one could see that the team led by Xia Zhiyi's three vaccinated people came out to deal with the zombies, as if they had been pushed out.

"Why did you bring him here too?" Xia Zhiyi frowned at Su Mian who was standing beside him, but the message was not that Su Mian was in the way, but that he was worried that something might happen to him.

But Xia Zhiyi obviously didn't have time to continue to ask about this matter. The roar of the zombies became more and more loud. When they turned their heads, they could see a large wave of zombies approaching the door.Even the zombies who were a little further away from the base were attracted by the movement here.

The glass window at the back of the truck was opened, and Lu Zhongshu said to Ferro who was sitting in the driver's seat: "Drive out of the base, we will attract the attention of the zombies, and take out as many as we can."

"it is good!"

After getting Fei Luo's answer, he looked at the other people on the truck: "Two people go down and close the door before attracting zombies, which one of you will go?"

The opening and closing of the doors of the base requires manual labor, so as to prevent the doors from failing and better control the height of the doors.The action of closing the door is more dangerous than the action of attracting zombies on the truck.

"Can't we just go?" There was a moment of silence in the car, and Yi Yan looked at Lu Zhongshu.

Lu Zhongshu didn't refuse either, and met Yi Yan's gaze.

"You're right, let's go, the two of us."
