The ghost said calmly: "When a marathon was held in Los Angeles, the United States a few years ago, a terrorist bomb detonated, which caused a lot of panic. A Chinese student was killed. The terrorist used explosives made of pressure cookers.

Because the pressure cooker has a very good sealing property, the effect can only be achieved when the internal pressure breaks through the peak. Do you know what the filler is? It is ammonium nitrate. Well, it is a kind of fertilizer.

The fertilizer "ammonium nitrate" is an extremely unstable substance. In the past few years, an agricultural vehicle filled with ammonium nitrate fertilizer exploded and destroyed most of the village. So the power of this thing is still considerable."

After the ghost said that, everyone suddenly realized that no wonder he said that there are some farms. Indeed, there are agricultural supplies shops on the farm, and hundreds of tons of fertilizers are piled up. It is not difficult to find ammonium nitrate fertilizers.

The ghost cleared his throat and continued, "We can bury some mines outside the corpse pit at some distance, use the principle of short-circuiting wires to lead out a wire, and when the target appears, the connection circuit forms a short-circuit detonation."

We were all confused when we heard it. The ghost said it very easily, but the specific operation was not that simple, right?

Ghost added: "I suggest we go back to the farm and pull back all the ammonium nitrate fertilizers we found, and then pile them on the hillside inside the valley. Don't transport them into the valley. That thing is more dangerous. When the landmines are made, I

Take the men to the hillside, and the women don’t participate.”

This sounds scary. I didn't show off this time and insisted on learning to do it. In my eyes, the fertilizer that the ghost mentioned is almost the same as explosives.

Seeing that we were still confused, the ghost introduced in detail: "This thing is made into a landmine. You have to be careful when using it. First, it is waterproofing and wrapped with plastic bags and tape. In addition, it is to avoid accidental injuries.

, Usually the wires are connected to a special control room, and no one is allowed to move without any movement. A dedicated person must be taken care of. In actual combat, the position can be set according to the terrain, that is, first set up the terrain to guide the zombies to the vicinity of the mine array, and

When the zombies attack the obstacle, a crowded and accumulated effect will inevitably be formed. The obstacle ahead is not broken, and the subsequent zombies are crowded up again. At this time, the detonation can achieve a better effect. However, the burial point is set.

It is necessary to carefully calculate that the maximum number of zombies is eliminated without causing major damage to the obstacles."

After the ghost said this, our hearts became clearer, so everyone decided to send some men back to the farm tomorrow to find the fertilizer ammonium nitrate.

That night, we closed the gate of the castle and sent a small team to patrol the roof of the castle. Others went back to rest and rest. This night, in addition to the whimpering roars of zombies falling into the corpse pit from time to time, we were still living

It's considered peace.

The next day, everyone got up early and went to the corpse pit to check. One night, the number of zombies falling into the pit increased a lot compared to yesterday. It seems that if no measures are taken, these zombies will be able to step on their companions sooner or later.

The body crawled to the side of the corpse pit.

I looked at the hillside opposite the pit, and there were suspicious figures and slight sounds deep in the weeds. This mountainous area is not peaceful. I wonder if Zheng Dali's guys have been taken to the nest by the zombies?

Humans, I have some sympathy, but thinking about their methods to the girls, I feel refreshed!

The corpse pit surrounded the valley without leaving any living mouths. In order to pass the big pit, we made several solid movable bridge ladders, erected high walls that could climb the castle, and knocked down to pass the corpse pit because the pit was too wide.

This bridge ladder is not solid and can easily break in the middle, so this bridge ladder is quite thick and solid, and it doesn't matter even if a strong man with a hundred kilogram step on it.

Ghost, Canaan, Sunshine, Tianxu, Chen Da, Shan Qi, Haiyang and more than a dozen men, with our assistance, passed the bridge ladder, and rushed to the entrance of the passage halfway up the mountain with the cover of weeds.

When they entered the wooden door, they would be able to move all the way until they went out of the cave on the other side of the mountain. We set up some obstacles at the entrance of the cave on that side, and could not stop the people who would cause damage, but could stop the zombies with simple minds.

.

They went back to the farm to find the ammonium nitrate fertilizer. I don’t understand this and thought ammonium nitrate was a fertilizer. Canaan said no, there are many kinds of fertilizers, including urea, diammonium, and ammonium nitrate are just one of them.

And the ghost's target is ammonium nitrate.

I silently prayed in my heart that they could find the fertilizer they needed smoothly and transport it back safely, and never have anything to do!

You know, the corpse groups have entered the mountain, and the environment outside the mountain can only be worse!

When they go, they will have to come back tomorrow as soon as possible.

We who stayed in the valley were not idle either. We were patrolling closely the corpse pit. When we saw zombies breaking free from barbed, we would get rid of them. The corpses at the bottom of the pit were accumulated more and more. If this continues, a wave of corpses will come over.

, you can climb up by stepping on the body of the previous zombie!

But now the risk of going down the pit to clean up the corpses is too great. Every minute, new zombies emerge from the mountain and fall into the pit. Aile and I looked at the piles of zombies that are getting taller and taller in the pit, and frown.

Frown.

"Sister Duo, you can't do it anymore. It's almost one meter high. Even the clumsy zombies can climb up on the body." Aile'er was worried.

"Okay, the pit must always be prepared to pick up the people who clear the corpse and provide cover." I had no choice but to dig the corpse pit in a hurry. In order to surround the valley as soon as possible and not to destroy the underground springs, we did dig.

It's too shallow.

Zhang Xiaomei and Adam, who were patrolling the valley with us, and Tang Xiao, a few more people went back immediately to call some young and middle-aged men to come over, and they did it as soon as possible. Some of them jumped to the bottom of the pit to carry the corpse, and transported it to the opposite side of the pit to pile it up, forming a

With a barrier, the corpse group will not fall into the corpse pit because of the blind present. If there is no human attraction in front of you, the zombies will turn around when they encounter obstacles.

During the cleaning process, they also carried the zombies trapped on the barbs to the pit. This job is very easy and they have to endure the stench that comes to their faces. Although they are all wearing gloves, they are also wearing them.

It is inevitable that some corpse liquid and rotten meat will be rubbed. The careful Tang Xiao distributes the masks we brought from the community to everyone, which can also relieve the pain of breathing close to the zombies.

Half-grown teenagers like Zhao Yue, Daningzai, Xingzai, and Xiao Zhan also joined the work. The women were responsible for guarding the ground inside the corpse pit and were always ready to cover them back to the ground in the valley.

There are many scattered zombies on the mountain, and they like to form groups, with at least four or five heads per wave. Zhang Xiaomei just pulled a dead body from Adam and Daningzai at the bottom of the pit, and then pounced on the weeds behind her.

A short zombie came out, and Zhang Xiaomei's two swords were still on her waist. Before she could draw the sword, the zombie was approaching!

We all saw the other side of the pit and screamed in surprise.

Zhang Xiaomei had no choice but to roll out to one side. The zombies were empty and fell into the corpse pit. Zhang Xiaomei had just breathed a sigh of relief, and two zombies rushed out of the weeds around her, only two meters away from him!

At this time, Zhang Xiaomei had already taken the opportunity with both swords. He quickly evaluated it. The zombie on the left was closest to him. In less than a second, he rushed towards the zombie and inserted the sharp blade into the zombie's temple.

At the same time, the zombie on the right had already pounced behind Zhang Xiaomei.

Zhang Xiaomei had just twisted her body, but saw the zombie behind her lying softly on the ground, and Tang Xiao's hands were still holding the short spear that pierced into the corpse's brain.

Tang Xiao had just dragged a dead body beside him and came over to free Zhang Xiaomei's encirclement in time.

"Brother, thank you! Oh my god..." Zhang Xiaomei didn't know Tang Xiaoyu's name. She was about to ask when she saw two other zombies crawling out of the grass behind Tang Xiaoyu.

Before he could warn Tang Xiao, he quickly rushed towards the latter with a knife, which scared Tang Xiao again. He thought that this guy was so angry that he even wanted to cut the knife, so he hurriedly flashed to the side.

When he realized that Zhang Xiaomei had already exploded the head of a zombie. Tang Xiao hurriedly used force to pull out the short spear from the head of the dead zombie on the ground and flew towards the remaining one.

The two zombies became dead without any suspense, and Tang Xiao smiled at Zhang Xiaomei again: "Thank you, buddy, will you repay the favor so quickly?"

Zhang Xiaomei glanced at the weeds with vigilance and replied, "I like others owe me more, hehe. What do you call me? My name is Zhang Xiaomei."

Tang Xiao was stunned again, obviously "shocked" by the handsome young man's beautiful name, but he quickly replied: "My name is Tang Xiaoyou, but I am Xiao from Xiao, where are you?"

Zhang Xiaomei saw that the grass became quiet again, so she turned back to Tang Xiao with confidence and said, "I am a small little guy. Xiaoyou guy, a few zombies pop up from the grass from time to time. We really have a little on the back of our heads.

Eyes, let's take turns, you look at the grass, I'll move zombies, if someone is tired after a while, then change them, what do you think?"

Tang Xiao thought about it again, and it was only like this. It was indeed quite dangerous when he was caught off guard by a zombie just now!

So the two set up a temporary group, one standing guard and the other working.

Adam and Daningzai were at the bottom of the pit and didn't know what happened. They couldn't see Zhang Xiaomei and Tang Xiaoyou at the location, but they could see a few of us. Only from our nervous expressions and screams did they understand.

A small danger that happened just now.

We were screaming in the pit, but we were separated by a big pit and couldn't get over to support us. In fact, I am very confident in the skills of these young men. With their reaction and combat ability, we will deal with these zombies.

It’s no problem, but it’s mainly because the incident happened suddenly, which scared us very much.

The others also learned from these two guys, working in groups, the weeds were too close to the trapped corpse pit, and only one person was sent to stand guard. Even if you issued a warning, it would be too late. You still need a special guardian partner, and the other person

Only then can you work with peace of mind.
