It was raining non-stop outside, and everyone in the shelter was a little gloomy, it had been several days, but General Lu had not been found, although he knew that General Lu might still be alive, but he had not come back for such a long time, everyone's heart was still a little uneasy, and bad things came one by one, yesterday a large group of zombies rushed to the shelter under black pressure, this time Liu Beep saw more than a dozen demons in the zombie group.

"Now we have to think about how we can fend off the zombies." There are many more zombies this time than the one in Xiadao, but Liu Beep feels that these may not be all zombies.

"Can the cannon kill all those zombies?"

"No, the reloading time of the giant cannon is relatively long, and the zombies are about to arrive, and now it is raining, so the sight is not clear, so the mortar is not easy to aim."

"Then we can only fight in close combat?" Everyone thinks that it is impossible for so many zombies to fight in close combat.

"Mortars can be used, but they are not aimed very accurately, and because of the rain, the filling of bombs will be slower, but I have built two layers of urn cities inside and outside, we can consume a little bit, and then use the cannon to blow up those demons, and we still have a lot of traps."

Liu Bi has prepared a lot of things this time, it shouldn't be that he has been preparing for these, after all, he has been guarding against the arrival of zombies again, and he doesn't regret that the materials of the second giant cannon are not enough.

At this time, the phone called and said that the zombies had appeared in the line of sight, Liu Beep immediately took everyone up, this time the zombies were obviously much faster than the last time, and the mortars had been placed in the outermost urn city, and they had already tried to fire a shot.

But the sight is not as good as when the sunny day is good, only a few sporadic shots hit, but the damage is not much, everyone is actively adjusting, but after the first shot is launched, the zombies have already run halfway, and seeing that the third shot is out, those zombies will come to the wall.

"Retreat to the second wall." Liu Beep directly ordered everyone to retreat to the second wall, and as soon as everyone heard it, they immediately retreated to the second wall, and then started from scratch to prepare for launch.

Liu Beep threw down the wooden plank used to connect the two walls, and then looked at the zombies, and the outermost wall had a lot of spikes made of iron, and some bombs were installed, Liu Beep believed that this would be able to resist them for a while.

But the accuracy of the giant cannon is not so good, after all, those demons are different from the previous one, which one of the people who came to the shelter before was very large, and they didn't need to aim and die with a shot, and the current demons were not fat, and the distance was too far for them to dodge during that time.

However, it was a bit of relief that some zombies were killed incidentally.

At this time, Liu Beep threw Xiaobai and the tassel down, he planned to let the tassel and them resist first, and the mortar continued to attack the back row.

Tassels and Xiaobai are two sharp weapons, and the tassel grabbed Xiaobai and rushed down, not to mention that this car can kill a lot of zombies after it gets bigger, so the speed of the zombies has been slowed down a bit, but now the zombies have arrived not far from the first city wall.

"Hurry up, hurry up!" In fact, the second platoon has already had some mortars here, and the operators here are all mercenaries Yes, mercenaries have appeared now, and these are all mercenaries recently, and their obligation is to help the defense of the shelter, so they have also been trained as mortars, but they have not been trained for a long time, so the accuracy is not very good.

Where are the tassels and Xiaobai killing zombie demons, of course, they won't agree that three or four demons are here immediately, Tassel and Xiaobai are fighting and pushing, they mainly drag down the speed of zombies.

Boom~ A huge cannon shot hit the zombie group, and now Liu Bi has also changed his strategy, he thinks that if the demons can't hit it, then just hit the zombie group, so that some zombies can also be reduced, after all, there are so many zombies, even if you don't use those demons, those zombies can kill Liu Bee.

However, the tassel and Xiaobai have almost reached the limit, and the tassel escaped immediately with Xiaobai, and Xiaobai also had some more wounds on his body, it seems that the demon is still powerful.

In this way, those zombies rushed to the bottom of the first urn city wall and began to attack the city wall, but when they rushed over, they still had to be pierced by the ancestors' iron thorns, and some were directly pierced by iron thorns, of course, it was useless for the zombies to be pierced, they could still move, but this also trapped them.

At this time, Liu Beep looked almost done, and pressed the button, and the bomb installed on the wall exploded, and the entire wall was directly exploded, and the zombie group was killed by the fragments that exploded directly.

However, the zombie group did not close these and continued to run on the wreckage of the city wall, and the mortars continued to attack, but there were still so many zombies, but the mortars and giant artillery had killed a large part of the zombies.

"Why are there so many zombies!" Liu Beep saw that he had already arrived at the zombie group under the wall, but now there was no way, Liu Beep could only lead some people to rush down, and first resist the zombie group, and couldn't let them attack the city wall, but they rushed up as soon as they got the demons and pseudo-mutants.

The tassel can resist three demons, Liu Beep can barely fight against one demon, Xiaobai can barely fight against two demons, and most of the rest of the people can barely fight against some demons and mutants, among which the more powerful one is Gu Yuan, she has now been promoted to the fourth order, fighting three demons alone, and has been pressing them to fight.

Unconsciously, the shelter has also accumulated a lot of masters, Liu Beep leaned on the vines to barely resist the demons on the opposite side, these demons don't know why, now they all start to use weapons, and their weapons are still very powerful.

Liu Beep is fighting against a female demon, her whole body is covered with purple scales, and she will be invisible from time to time, but although this demon will be invisible, she still holds two shiny daggers in her hands, but in terms of strength, it is really not very good.

Liu Beep can't still kill one or two zombies, this demon seems to be very timid, as soon as Liu Beep becomes fierce, she will be invisible, and then find an opportunity to sneak attack.

"I'll go." At this time, Liu Beep's arm was cut, and Liu Beep immediately stabbed it, but nothing hit.

It seems that this demon knew that Liu Beep was wearing rattan armor and hurt Liu Beep, so he began to look for Liu Bee, who was not wrapped in rattan armor.

However, at this time, the rattan armor on Liu Bee's body suddenly became more wrapped in the whole body, and the previous rattan armor only had some on the legs of the upper body and the armor and lower body, and now not only the head but also the others Anyway, the whole body has been wrapped in rattan armor.

The demon was startled when she saw it, and it seemed that she had no way to attack.
