Chapter 686 The most dangerous moment has come! [5000 character chapter]

The floodwater rushed into the mountains and forests outside the base. It just reached the rural road and began to fall back.

As you can see from the camera, the floodwaters are falling back very quickly.

It soon fell back to about one-third of the distance from the national highway to the rural road in the Da Zhangshu base.

In the duty room.

Li Yu looked at the chair that he was slowly loosening his grip on, and looked at the cheering crowd with a smile on his face.

Immediately, he said to Li Tie: "Tiezi, fly the drone and check the situation further away."

Upon hearing this, Li Tie immediately stood up, picked up the drone from the table in the corner, opened the door of the duty room, and placed the drone in the heavy rain.

Li Hang has equipped this drone with a small raincoat in the past two days, mainly to protect some key parts from getting wet from the rain.

Buzz——

The drone took off quickly. The rain was heavy and hit the drone. Just as a strong wind blew, the drone shook violently and almost hit the wall.

Li Tie quickly raised the height of the drone.

The drone flew dangerously over the duty room. Watching the drone slowly rise, Li Tie finally breathed a sigh of relief.

As the drone rose higher, the duty room gradually became smaller. Looking out over the base, Li Tie couldn't help but gasp.

Outside the base, where the rural road is, many zombies slowly walked out. These zombies got up from the water and came straight to the Da Zhangshu base.

"Brother, come and take a look, there are so many zombies!" Li Tie turned around and shouted to Li Yu.

When Li Yu heard this, his eyes narrowed and he hurried over.

At present, there are nearly two thousand people in the base, including inner and outer cities, plus cooperative personnel and non-staff personnel who have not been released.

This amount of population will inevitably attract a lot of zombies.

This time the flood washed away all the zombies in the northern city.

The zombies are like a tidal wave, and the zombies in the water are really like a tidal wave, a mass of darkness.

As the flood flowed, many zombies were rushed to the side of the country road. It seemed that because they smelled the strong human breath here, these zombies tried their best to resist the force of the flood and swam to the side of the country road. .

The flood was so strong that it pushed some zombies up, and also washed some zombies farther downstream.

Seeing this scene, Li Yu immediately ordered: "Everyone go to the fence and observe the situation of the moving knife at any time. If the height of the pile of zombies in that direction exceeds ten meters, open the second layer of moving knife."

The crowd rushed out armed with firearms and raincoats.

It rained heavily.

Everyone braved the heavy rain and quickly dispersed to various locations on the wall.

The duty room towards the cliff.

Originally, this place was nearly ten meters shorter than the main entrance, so the drainage of the Da Zhangshu base was discharged in this direction.

The rainwater flowing down from the mountains and forests also gathers here.

When the floods rushed over, they also poured into the lake under the cliff.

The water level of the cliff lake quickly rose to a height of forty or fifty meters.

The edges of the lake were flooded, and the water flowed further downstream. However, the valleys downstream were also flooded.

Fortunately, the drainage outlet of the Dazhangshu base is still dozens of meters away from the highest water level. As of now, it is still safe.

But with the heavy rain and floods, zombies not only appeared at the gate, but also appeared in all directions of the wall.

At a height of more than 7 meters on the wall, the mobile knife on the first floor is constantly operating, creating a sharp blade.

Keep cutting some stacked zombies in half.

The bodies of many zombies were severed from the waist. Half of them flew up one or two meters, and then fell heavily down.

The other half collapsed directly into the pile of zombies and was quickly devoured by the zombies inside.

Clang, Clang, Clang——

The sound of moving the blade is loud, but it is not very noticeable in the heavy rain.

The rain was pouring, slapping against the walls and raincoats; the occasional thunder and lightning sounds were louder than the sound of the blades operating.

Boundless zombies come rolling in.

This is the time when Dazhang Base has faced the most zombies.

It was also the heaviest rainstorm ever.

In the heavy rain, these zombies are not afraid of death, and their stacking speed is twice as high as before.

soon.

In the direction of the west gate, there are Yang Tianlong, Li Zhengping, Wang Cheng, and Lao Qin.

Staring at these zombies, they moved super fast in the heavy rain, almost able to match the running speed of an adult.

It was as if someone had been given an adrenaline shot, full of madness.

The current wall height of the base is 28 meters.

The mobile knife is divided into three layers:

The first layer: distributed at a height of seven meters, with the largest thickness and number of guillotines.

Second level: Distributed at a height of thirteen meters, the knife is the fastest and can quickly cut off the heads of zombies.

The third layer: Distributed at a height of 20 meters, the switch blades are sharp and relatively thin, and the last layer of protection.

The swarming zombies quickly piled up to a height of seven meters desperately, and were quickly swallowed up by the knife.

The knife made an unpleasant friction sound and seemed unable to bear such a heavy weight.

Kakaka——

Yang Tianlong hurried to the duty room and shouted to Lao Qin: "Open the second-floor mobile gate knife quickly, quickly, quickly!"

Lao Qin did not hesitate and directly opened the mobile gates on the second and third floors.

Buzz——

On the fence.

At a height of 13 meters or 20 meters, two levels of movable blades extend out.

The moment the knife was extended, the heavy rain hit the cold blade of the knife, making a roaring sound.

After the thick blade stretched out, it began to rotate slowly.

There are three layers of movable knives. The middle layer of movable knives rotates clockwise, and the upper and lower movable knives rotate counterclockwise.

The zombies were stacked very fast. After reaching a height of seven meters, because there were too many zombies, several of the guillotines were temporarily suppressed. Make the speed of the knife become extremely slow.

Continue to stack higher on the wall.

ten meters.

Thirteen meters.

The zombies are stacked up, taking on the shape of a triangular pyramid.

△

It's just that there is a right angle of ninety degrees near the wall. /|

The higher you go, the fewer zombies there are.

Clang, Clang, Clang——

The zombies who climbed to this height were quickly decapitated by sharp blades.

The upward stacking speed of the zombies suddenly stagnated, and the progress of climbing up suddenly froze.

On the other side, Li Yu saw zombies stacking up very fast at the gate. So the base alarm was sounded directly, and the danger level was raised to level two.

And asked Li Hang to open all the three-layer gate knives on the fence here and increase them to maximum power.

There is an area in each duty room where the blade can be controlled.

But the duty room at the gate can control the duty rooms in all directions on the fence.

After the three-layer gate knife was opened, the tide of zombies climbing towards the base of Da Zhangshu from other directions slowed down.

The wave of zombies rushing over this time was too ferocious.

Perhaps because they have been soaked in water for too long and their strength has been strengthened in the heavy rain, these zombies have become extremely mobile!

The maximum power of the mobile knife is turned on, and its strength is strengthened.

In an instant, the mobile gate knife, which was suppressed by the zombie wave at a height of seven meters on the wall, moved suddenly to both sides like a wild horse running wild.

Wow——

At the front entrance, the wave of zombies that were originally stacked in a stalemate at a height of thirteen meters suddenly collapsed.

The zombies at a height of seven meters under the wall were directly thrown away by the knife.

The zombie wave is like stacked building blocks, with the middle layer removed.

The zombies that were more than seven meters above the ground fell straight down.

The tide of zombies collapsed.

Everyone's hearts, which had been hanging just now, suddenly fell to the ground.

Everyone on the wall realized that this zombie wave was unusual.

The tide of zombies collapsed, and many zombies died under the wall.

Immediately, many zombies focused on those dead companions and gnawed on them.

Li Yu remembered an experiment done a few days ago, which was to kill zombies in the distance, and then attract some zombies to pile up in the distance.

So he immediately took out the walkie-talkie and shouted to everyone on the wall:

"I'm Li Yu. Pay attention in all directions. The wave of zombies is too fierce this time. You can use the experimental method we did at the front door to kill the zombies in the forest tens of meters away, and reduce the speed of the knife on the side of the fence." Pressure. Don’t be stingy with bullets and shells, the first priority is to protect the wall and defense line!”

Li Yu took the walkie-talkie and repeated it three times.

Replies came from other directions.

"receive."

"receive."

"receive."

"receive."

Almost at the moment when the news was sent out, Yang Tianlong raised a bazooka from the duty room, and fired a cannonball towards a mountain depression tens of meters away.

In the heavy rain, the shells with a red tail light went straight to the mountain where the zombies ran over.

bang——

The shells blasted away a large area of ​​zombies, and in the heavy rain, the corpses of the zombies were blown into several pieces.

Li Zhengping also took a submachine gun and shot in the direction Yang Tianlong had just shot.

The bullets kept pouring in that direction like running water.

There is a wooden box next to him, this wooden box is specially used to put some bullet casings.

In the apocalypse, bullets can still be made, but bullet casings involve too much and are very troublesome to make.

So basically, the bullet casings they use are recycled and reused.

In the heavy rain, the gunfire at the base rang out loudly.

Li Yu looked at the zombies under the wall, and was attracted by the dead zombies in the forest. The tide of zombies that were originally six or seven meters high gradually decreased to only four or five meters high, and he breathed a sigh of relief.

The situation was critical just now, so he also shot and killed the zombies in the woods.

But he also felt sorry for the bullets, so after the situation improved, he changed into a crossbow and shot at the zombies on the other side of the mountain forest on the wall.

The sky was as black as ink, and the accuracy of shooting with bullets was not high.

So Li Yu asked Li Hang and Cannon to take out the necessary searchlights on the wall, take out one light to illuminate the distant forest, and move the other light to see if there is a relatively high pile of zombies around the wall.

Under the illumination of the searchlights, the mountains and forests in the distance can be seen more clearly.

The distance is only thirty or forty meters.

In addition to more electricity in the base now, there are more arrow feathers.

Some time ago, I asked non-staff and cooperative staff to make a lot of arrow feathers.

In the third-level combat readiness state, more than a hundred people including Lao Luo, Lao Bi, Lao Yi, Lao Qin, Lao Zhou, He Bing, Ju Tianrui, and Xiao Jun among the people from the outer city were on the entire wall.

Now, nearly three hundred people gathered on the wall.

Almost every few meters on the fence, there is a person standing on it guarding the fence.

Bows and crossbows are distributed to everyone, together with firearms and shells to block zombies.

There are a total of sixteen high-beam searchlights on the entire fence. At the gate, except for the two on the watchtower and the two outside the duty room, all of them are turned on.

In addition, there are fifty solar street lights on the fence, which were originally used with cameras, but are now all turned on.

In the big camphor tree base, under normal circumstances, basically just turn on the solar street lights.

Searchlights are not used frequently, in the past to save energy, and later to make them less conspicuous in the dark.

But at this time, all of this was forgotten.

A searchlight, just the light bulb has a washbasin, so standing next to the searchlight will feel a little hot, and the power consumption is astonishing.

It is because of the zombie generator that they dare to spend so much.

A searchlight, in the absence of rain, can shine hundreds of meters away, very bright.

At this time, all of them were turned on, and outside the big camphor tree base, it was as bright as day.

The water droplets were like lines, which slightly affected the illumination of the searchlight, making it unable to shine farther. However, it was still able to illuminate very clearly dozens of meters away from the base.

A wall as bright as day.

Boost the morale of everyone on the wall.

Looking at the zombies outside the wall, Ju Tianrui's scalp felt a little numb. When he heard gunfire in the outer city just now, he felt that the situation was a little critical.

But when he was called up by He Chao, he saw that the zombies climbed almost half of the height under such a tall wall.

Zombies stacked up to a height of more than ten meters!

And even with the mobile knife, they can still be stacked so high.

Really scary.

Later, I learned from Yang Tianlong next to me that the flood was a disaster.

When he heard that the rural roads outside the base were flooded, he was a little shocked.

After all, the big camphor tree base is on a high ground. If the country roads halfway to the national highway are submerged, what about Xincheng?

Just thinking about it makes my teeth sore.

Holding a bow and crossbow, he aimed in the direction of the searchlight and shot at the head of a zombie.

Whoosh——

The arrow feather cut through the rain line and successfully hit the head of a zombie.

The zombie fell down, and several zombies came quickly from all directions to snatch the corpse of the dead zombie.

But there were two zombies, just after touching the body of the dead zombie, they were shot to death by Yang Tianlong and others next to them.

These zombie corpses are like a snowball, getting bigger and bigger.

There are zombies being shot to death constantly, attracting the attention of zombies who have just arrived here, and successfully reducing the pressure on the switch knife under the wall.

Finally, it all fell into a balance.

Some of the zombies were scattered around the wall and piled up, but the highest height was 7 meters and they could no longer climb up.

The reason is that another part of the zombies, attracted by the corpses of the same kind, ran towards the pile of zombies in the forest outside the wall.

Under this strategy, the base finally returned to a relatively safe state.

The floods continue.

The melting snow from the Tanggula Mountains, coupled with heavy rains in the upper reaches, concentrated into the dam and submerged it.

This flood will never end as long as the heavy rain continues.

After the situation stabilized, Li Yu patrolled around the wall and appointed several people in charge to be responsible for the protection in their respective directions.

Once a problem occurs, people on the left and right must go to support.

Under the heavy rain, everyone fought in the rain and maintained a certain balance.

Li Yu made a schedule. The heavy rain was still falling, and it was impossible for all of them to be on the wall all the time.

A detailed battle plan must be developed.

Five duty rooms, 300 people.

The duty room certainly cannot accommodate that many people, and it is not necessary to stay in the duty room. It is just that five teams are set up based on the duty room.

This side of the main entrance is duty room No. 1.

Li Yu is the person in charge, and the secondary person in charge is Li Hang. In addition, Lao Yi and others are assisting here.

Duty room number two.

The third uncle is the person in charge, the second person in charge is Lao Lu, and Lao Qin and others are around to assist.

Duty room number three.

The uncle is the main person in charge, Li Gang is the secondary person in charge, and Ju Tianrui and others collaborate.

Duty room number four.

The second uncle is the main person in charge, Da Pao is the secondary person in charge, and Xiao Jun and others cooperate.

Duty room number five.

Li Tie is the main person in charge, Yang Tianlong is the secondary person in charge, and Lao Zhou and others collaborate.

There are three hundred people, except for the No. 1 duty room at the main entrance, which faces the greatest pressure, so it is equipped with one hundred people.

Fifty people were arranged in other directions.

In addition, the total number of people in the inner and outer cities is 400, except for these 300 people for protection.

In the outer city, He Chao led 20 people, armed with firearms, to control order in the outer city.

In addition, Zhu Xiao, Zuo Ruxue, Guo Peng and other non-staff personnel were asked to control those collaborators in the outer city.

Once you find someone who wants to take advantage of the opportunity to cause trouble, they will be killed without mercy!

In addition, Li Yu simply asked these collaborators to assign some less important tasks and found something for them to do.

In the inner city.

Let Ding Jiu, Li's father and others hold firearms and form an inner city team to protect the stability of the inner city.

In order to provide stable logistics, Li Yu asked Li's mother and Yutong to bring twenty or thirty people to supply food and other things.

The closer the crisis comes, the clearer Li Yu becomes about one thing.

You can’t use someone you don’t trust enough!

Human nature is greedy, and human nature is inherently evil.

Otherwise, before the end of the world, in some countries outside, every time there is turmoil, there will be burning, killing and looting.

He won't give those collaborators in the outer city a chance.

In fact, being able to get people from the outer city to come up is already his bottom line.

These people in the outer city, after getting along for so long, most of them are members of the army.

Moreover, they were assigned bows and crossbows, and there were various responsible persons in charge, so the chance of problems was not high.

Now a grasshopper in a boat.

A battle plan was drawn up, and the tide of zombies outside the wall was stabilized by the use of the two methods of using switch knives and crossbow shooting to attract the attention of zombies.

People who did not need to come up in two shifts began to return to their respective posts.

After the tide of zombies stabilized, the number of people on the base returned to 150.

No one can fight for a long time 24 hours a day.

Even working in two shifts already made them exhausted enough.

The zombies outside the wall seem to be endless, and they keep coming here.

But no matter what, Da Zhangshu Base finally managed to survive heavy rains, floods, and waves of zombies!
