"What?" Liu Bi was also startled after listening to General Lu's words, and kept thinking about it in his head, seeing what way to resist it if the zombies found out about the refuge.

"Let's make these crystals into potions first, and let the three captains pick the ones that perform better and let them use the potion." Liu Bi asked General Lu to find the three captains, and then he took the crystals given to him by Moya and went to the seventh layer to make the potion.

Moya brought back a total of five crystals, and there were originally many crystals, but Moya was scared away by the mutant before he could pick them up.

Five crystals were put in, and soon the five potions came out, and after waiting for a few minutes, General Lu and the three captains came down with five people.

Among the people who have used the potion before, only Lu Wen and Ye Qiguang have mutated special abilities, Lu Wen's bullet time, which is an ability to slow down the speed of time, Ye Qiguang's ability is very magical, it can metalize the whole body, which can make his body stronger, just like metal.

Each of the five people took a bottle and drank it, but unfortunately the five people mutated a special ability alone, I didn't expect that person to be Brother Dong, and the ability he mutated was more practical than being able to make it huge, that is, to make the whole body bigger.

"Okay, let's get acquainted with it, and what's your name?" Liu Beep asked everyone to familiarize themselves with their improved body, and then asked Dongge's name.

"Hello director, I'm Lin Dong of the third team." Lin Dong showed a panicked expression, but judging from the words and tone, it was not as manifest, and the mutated special ability was also in his pocket.

"Lin Dong is very good, master your ability well, and the future shelter will depend on you." Liu Bi didn't care about Lin Dong's current state, now for him, as long as he could resist the attack power of the zombies, he would not be angry with any attitude towards him.

"Okay, let's go down first, we need to have a good talk."

After a few people left, General Lu and the others were a little angry at Lin Dong's attitude, and the others were fine, but Ye Qiguang, the captain of the third team, lost his temper.

"What does Lin Dong mean, did he pretend before?" Ye Qiguang was very angry, he used to think that Lin Dong was a very humble person and friendly to others, but he didn't expect a 180-degree turn in his attitude as soon as he mutated, which made Ye Qiguang feel cheated.

"Alright, okay, sit down." Liu Bi felt that he still needed a place to sit down, so he let the system build here, without too much decoration or anything like that, it was just a big round table and chairs, General Lu looked at Ye Qiguang, who was furious, and immediately asked him to sit down first.

"No matter what his attitude is now, these things will be put later, and the main thing for us now is to think about how to deal with the upcoming zombies."

"yes, but will the zombies find us? We shouldn't be found hiding in the vault, right? ”

"Not necessarily, we don't know what the mutants in those zombies are, so we can't be sure that the zombies won't find us." Ye Qiguang is not wrong, mutants cannot be compared with ordinary zombies.

"Anyway, we're going to prepare according to what they'll find, and we can't let everyone go up to the ground floor and seal off the ground floor now." Liu Bi still thinks that the worst plan is used to prepare, the central garden on the ground floor is a lot of places that like to go, because the sunlight here is the best, and you can see the sky, and the top of the central garden on the ground floor is a large piece of transparent tempered glass, and everyone likes to stay here whenever they have time.

In the current period, people must not stay on it, and if the zombies really come, they will not be harmed.

"Agreed, but can we only defend passively?" Gong Jianjun was very helpless that he could only defend passively.

"There's nothing we can do, but can we do a trap outside?" General Lu thought that he could make some traps at the gate of the shelter, after all, passive defense is very difficult, if you can use traps to destroy some zombies.

"Yes, zombies don't want people, and they are very lethal to traps. Let's dig a few big holes and stick some spikes and stuff into them. Liu Bi thought this idea was very good, so he agreed with General Lu to get it.

"Well, I'll leave this matter to you for a team, by the way, the director doesn't know how about the defense of our gate? If the mutant comes, will the door be able to resist it? ”

Speaking of the gate, Liu Beep was also very helpless, after all, it had only been long since the gate was repaired, but now it may be destroyed again.

"The gate can defend against ordinary zombies, but the attack power of mutants is unknown."

"How do you defend the gate when it's opened?"

This is a big question, what if the zombies come in?

"yes, what should we do if the gate is broken, no, we must not let the gate be destroyed." Liu beep slapped the table, he absolutely couldn't let the zombies in.

"Then just guard the gate, you go and have people prepare a longer weapon, and I will build an urn city at the gate."

Originally, Liu Bi wanted to wait until there were more materials to fence off in the shelter, but now there is no way but to build a small urn city in front of the gate with the remaining materials.

After the urn city was built, the people of the material team were shocked when they came out, but they had already attributed this ability to the ability mutated by Liu Beep.

"How are we going to go down?" The members of the team holding the shovel were a little puzzled, this Gong Jianjun brought a few hemp ropes, the urn city was not very high, only two meters high, and the people pulled the rope and went down to dig the soil, and then the people of the other teams began to carry the spikes, most of which were wooden spikes cut down from nearby trees.

"There are humans on the queen's side, and there is a lot of energy." The mutant who didn't have any zombie traits said.

"Well, let the green and yellow hairs go." Although the zombie queen won't care about them devouring each other, she still wants to control it, so that this opportunity must be given to the yellow hair and the green hair, the mutant seems to have guessed it early, nodded and ran to inform, the green hair and the yellow hair were very happy to receive the news, and set off in the direction of the mutant, and the zombie queen also added the green hair's zombie group, which made the green hair more confident in what would happen later.

Green Fur thought to himself that he must get more this time, and if possible, he must eat Yellow Fur together.

Green Hair thinks like this, Yellow Hair actually thinks the same way, and he has made a lot of preparations.
