[5000-word chapter]

The floodwaters rushed into the mountains and forests outside the base. They 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 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, overlooking the outside of the base, and Li Tie couldn't help but take a breath.

Outside the base, where the rural road is located, many zombies slowly walked out. These zombies climbed 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, 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 washed to the edge of the rural road. It seemed that they smelled the strong human scent here, so these zombies tried their best to resist the force of the flood carrying them downward, and instead swam towards the rural road.

.

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

Li Yu saw this scene and immediately ordered: "Everyone go to the wall and observe the situation of the moving knife at any time. If the stack of zombies in that direction exceeds ten meters, open the second level of the 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 facing 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 valley downstream was also flooded.

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

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

At a height of more than 7 meters on the wall, the mobile knife on the first floor is in constant operation, producing a sharp blade light.

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 heavy rain.

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

Endless zombies are rolling in.

This is the time when Dazhang Base has faced the largest number of 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 as fast as an adult.

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

The current base wall height is 28 meters.

The mobile knife is divided into three layers:

The first layer: distributed at a height of seven meters, has 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 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 then the knife was quickly swallowed up.

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

Kakaka——

Yang Tianlong quickly ran 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 stacked up very fast. After reaching a height of seven meters, because there were too many zombies, several of the knives were temporarily suppressed, causing the speed of the knives to 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 that climbed to this height were quickly decapitated by sharp blades.

The zombies' upward stacking speed suddenly stagnated, and their climbing progress suddenly froze.

On the other side, Li Yu saw the zombies stacking up very fast at the gate. So he immediately sounded the base alarm, raising the danger level to level two.

And asked Li Hang to open all the three-layer gate knives on the fence here and increase them to the 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 tide 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——
