The Vault began to tremble unknowingly, and a very large hole appeared in the ceiling of the basement floor, which turned out to be a pseudo-mutant whose ability was to self-detonate, and he came to blow up the entire parking lot.

"!" Seeing that the zombies began to enter the underground, Liu Beep scolded, he didn't expect that there was such an ability, the ability of that pseudo-mutant can only be used once, but the power is actually great.

There is no way, Liu Beep can only let the system quickly repair the ground, and then take some people to the basement layer to kill the zombies that run down.

The rest of the people continued to defend on it, and the first basement floor had been destroyed, and although the explosion did not destroy the second basement, the basement floor was blown up in a mess by the explosion.

There are about hundreds of zombies running to the basement level, and Liu Bi has only brought more than 20 people down now, but there is no way to do it, after all, there is more need for people on the ground now.

Liu Beep pulled up the seat with vines and smashed them at those zombies, he didn't think that he could kill these zombies by relying on them, so he could only rely on the vines to attack, although the vines strengthened his strength, but they did not give full play to the power of the star vine, the star vine is a very magical vine, its own strength is very strong and the power of the amplitude does not emit its full power.

Now Liu Bi is already planning to be a summoner and beast trainer, and now he wants to exert the power of vines.

Xingteng pulled up the seat and smashed it at the zombies who were a little farther away, while Liu Beep took a knife to kill the zombies who approached.

Although there was nothing to do on the second basement floor, there was still a sense of tremor, but fortunately, at this time, no one here would have been scared and screamed, but the ceiling was still covered by some dust and other things on the plants.

Liu Beep commanded the vines to pull the tables and chairs and smash them at those zombies, the vines were obviously much more powerful than Liu Beep, and the four vines grabbed the tables and chairs and could knock down several of them, and soon half of the hundreds of zombies were already dead.

"Well, it looks like I'm really too weak." Liu Beep saw that there were fewer and fewer zombies and felt that he was really too weak, and he obviously didn't develop all the abilities of Xingteng before, and he had always used Xingteng as a protective gear and a drawstring to use, but now it seems that his previous ideas were wrong.

"It's good that I don't think I'm suitable for recklessness." As a post-90s generation, I naturally have a martial arts dream in my heart, but now it seems that it is better to stay behind.

"You go up and help defend it, I'll leave it to me." Liu Bizhen said to the people behind him, but he didn't expect it himself, but now it's okay that these people can go back to defend.

The ground has been repaired, but now the repaired ground is not as hard as before, and Liu Bi can feel some debris falling from it when he is fighting, and it may not be long before this place will be blown up.

"Damn, I'm out of material now!" Liu Bi was a little worried, there were not many materials in the shelter, and now the shelter was not self-sufficient, and all the materials were found from the outside, and the number of times the shelter went out in recent times was relatively small, and the resources brought back were naturally relatively few.

And the urn city that has been built and repaired several times before, as well as the two city walls, are very consuming of those building materials, although some can be recycled later, but some will still be lost.

The situation on the basement floor is quite good, but there is not so much optimism on the ground, now the commander is Gong Jianjun, Gong Jianjun looks at the zombie group with a dark face, and now he has been fighting for more than two hours, everyone is already very tired, even if they are strengthened, they are already exhausted, after all, they have been fighting without stopping, but there are still so many zombies, he doesn't know how long it will take him to kill these zombies.

"Team Gong, it's not good, the ammunition for the mortar is running out!" At this time, a person suddenly shouted at Gong Jianjun that his ammunition was about to run out, and the others also found that their ammunition was running out at this time.

"What!" Gong Jianjun was shocked that mortars were a very good weapon to deal with these zombies, if the ammunition was gone, their lethality would drop a lot, and General Gong glanced at the box beside him, and there were only two Molotov cocktails left.

Gong Jianjun immediately ran to the material management office, he wanted to know if there was anything else that could be used, as for the Molotov cocktail and ammunition, don't think about it, because Liu Bi had already taken out all the things.

Except for some ammunition and mortars that were lost outside, the rest was basically used to deal with zombies.

There is no one here anymore, Gong Jianjun doesn't care about those who directly destroy the door and then rush in directly, it's still very big, but Gong Jianjun has also been here several times, so he ran directly to the place where the weapons were stored, but there are not many things here, and after all, the shelter is generally not collected, and when he saw that there was nothing here, Gong Jianjun immediately left.

"Why is there nothing left?" Gong Jianjun went around several places, only to find that some of the materials in the shelter had been used up at this time, and seeing that there was nothing left, Gong Jianjun could only run out, at least after going out, he could kill a few more zombies.

Gong Jianjun went in for a few minutes, but a lot of changes had taken place outside, the mortar ammunition had run out, the ceiling of the basement floor was broken again, some zombies began to run to the basement floor, and most of the remaining zombies began to impact it.

Boom, the last Molotov cocktail was smashed out, and everyone was already holding the weapons in their hands, ready to wait for the zombies to rush up, and then they also rushed over to resist the zombies.

"What now!" Gong Jianjun raised his head and sighed when he saw this scene, and then rushed out as well, he couldn't let these zombies rush in, there were still his wives and children inside.

"!" Liu Bi now also had to wield the knife in his hand, there was already a circle of zombies around him, even if Xingteng was so powerful, it still couldn't withstand such zombies, Xingteng was only second-order after all.

Now the four vines are pressed by a lot of zombies, the vines can't struggle, and Liu Bi has no way to get the vines out now, he can only barely resist now.

"If I die, I must survive and contract a powerful mutant beast again." Liu Pi gritted his teeth, he had already decided that if he survived, he would immediately find a powerful mutant beast, he really didn't want to continue like this.
