The doomsday sky is covered by thick clouds, and the world seems to be shrouded in gray.

The heavy snow was as gentle as a feather, but swept across the earth ruthlessly, covering everything with a layer of cold white. The snowflakes danced in the air, spinning and floating, and finally fell on the wall.

Snowflakes cover the top of the wall, like a layer of fine white silk, while the snow on the inside of the wall has formed hills, and the winding paths taken by people can be vaguely seen.

buffer city.

Jie Changshan looked anxiously at the convoy coming in from the gate, and then looked behind him. There were dozens of trucks lined up behind, and the trucks were filled with stones and sand.

These sand and stones were prepared to fill and seal the door after Zhang Rufeng and others came in.

As one car after another drove in, Jie Changshan's nerves were tense and he did not dare to relax for a moment.

He has been working continuously for two days and has not slept for 48 hours.

Not sleeping for the past 24 hours made him extremely uncomfortable.

But more than 36 hours later, his brain became extremely clear.

At this time, he began to feel drowsy again. He squatted on the ground, holding a handful of snowflakes in his hands, and rubbed his face vigorously. The cold snow made him wake up instantly.

He stamped his feet to warm up his body.

The hot breath you exhale drifts away.

Ten minutes later.

Chen Er, who was at the back, drove in the last car, opened the window and shouted to Jie Changshan:

"Commander Xie, everyone has come in, we can seal the city!"

"good."

Jie Changshan was shocked when he heard this and shouted towards the truck convoy behind:

"Lao Fang, let them drive over and start blocking the east gate!"

After hearing what Jie Changshan said, Fang Jingxin, who had been waiting for a long time, immediately asked the truck convoy behind him to take action.

A truck loaded with gravel drove over, reversed the truck, and more than 20 tons of stones on the truck bed tilted out.

The surface of these stones was covered with a layer of snowflakes, but because it had just snowed not long ago, the ice and snow were not frozen particularly tightly, so they fell over and scattered on the open space in the middle of the gate.

Then another car drove over and tipped over.

They moved very quickly, dumping truck after truck of sand and gravel.

Ten minutes later.

The gate, which was originally nearly ten meters high, now only has the last two meters left.

During this period, there were some members of the Civil Armed Services Department on both sides of the gate watching, guarding against zombies from outside taking advantage of this gap to get in.

In addition, where the sand and gravel are dumped, there are excavators and forklifts to push the sand and gravel up and try to leave a better road for trucks to drive on.

In the last two meters of space, the excavator climbed to a slope made of sand and gravel.

There are hundreds of cubic meters of sand and gravel piled underneath.

Bang, bang, bang!

Use the excavator bucket to dig up the sand and gravel next to it and try to fill the gap between the bottom and the top of the gate.

The most efficient among them is the Doomsday Big Mac. This doomsday chariot was transformed from a giant loader. With the bucket installed, it can scoop up nearly 40 cubic meters of sand with one shovel.

Equivalent to the volume of sand that a heavy truck can load.

Under the operation of the giant loader, another ten minutes passed.

They blocked the East Gate completely and tightly.

The width of the buffer city wall reached 6 meters. They not only blocked these six meters, but even extended it by four to five meters behind the wall.

If there are people or zombies outside who want to dig in, they must dig at least ten meters before they can dig into the buffer city.

Moreover, as time goes by, this pile of sand will be covered by snow, melt, and finally condense with sand and gravel into a huge and hard object.

At that time, if people or zombies from outside want to come in, they will never be able to come in unless they use bombs to explode or use a large drilling rig.

In other words, we have to wait until the weather gets hotter and the snow and ice melt, and excavation will become easier.

"Stop! That's enough, let them stop!" Jie Changshan saw that the east gate was almost blocked and immediately asked Fang Jingxin to stop.

Boom boom boom——

Crunch——

The giant loader stopped.

Dai Jiusheng, who was driving the loader, patted the steering wheel and sighed:

“It’s so exciting!”

In the past, he often saw this Big Mac in the trading market, and he often saw people repairing and maintaining this Big Mac.

But there is a barbed wire fence around to prevent people from getting close.

After driving today, the experience was great and he felt the dominance of driving a super large loader.

"Hey, Lao Dai, Fang Gong asked us to drive this car back to the trading market." Behind Dai Jiusheng, Liu Hengshan patted his shoulder and said.

"Okay."

.......

On the buffer city wall.

Dongfeng saw Jie Changshan and the others stopped below, and knew that the east gate of the buffer city was blocked.

"Finally, everything is sealed."

Sizzling——

At this moment, the intercom suddenly rang.

"Captain, there is a group of survivors outside the south gate who want to come in. We told them that the city has been closed, but they still won't leave..."

After hearing Liu Youguang's voice on the intercom, Dongfeng cursed in his heart:

Damn it, it was such a coincidence. If you didn't come earlier, you wouldn't come later. You had to wait until the door was completely blocked before you came.

"Leave them alone, don't let them in."

Putting the walkie-talkie away, Dongfeng thought about it and decided that he still had to go and take a look.

In just a few hours, five to six centimeters of snow had fallen on the fence.

He stepped on the snow with one foot deep and one foot shallow, and walked towards the south gate.

He and Zhang Tianfu jointly guarded the buffer city wall. He was responsible for the east and south areas.

Zhang Tianfu is responsible for guarding the west and north sections.

He walked from the east gate to the south gate for a while before he got here.

When he arrived here, the group of survivors outside the south gate still hadn't left.

"The captain, that is, they were unwilling to leave even to death. They even wanted to dig out the sand and gravel below, but they gave up after digging for a while."

"Also, two waves of zombies came just now. I saw that they couldn't resist, so I helped them and killed those zombies."

This chapter is not over yet, please click on the next page to continue reading! The south gate has been blocked with sand and gravel for two days. In such cold weather, it has already frozen, and it is impossible to dig it open with manpower.

Dongfeng looked at the group of survivors below, there were about thirty people.

Each one looks like a little snowman in the blizzard.

There were still more than a dozen corpses lying on the snow. It was unknown whether these corpses were their people or the zombies that Liu Youguang and the others had killed just now.

After thinking for a few seconds, Dongfeng picked up the horn and shouted at them:

"I'm the person in charge here. You go away quickly. We can't let you in. Go away quickly. If zombies come later, we won't help you anymore."

Under the wall.

The survivors who were shivering from the cold surged.

One of the men, who was carrying a black cloth on his head, lowered the black cloth on his head.

His face was red from the cold, and he raised his head and shouted upwards with a trembling voice:

"My name is Chang Yichang. Please let us in. We really can't hold on any longer."

"There are women and old people in our team. Even if you don't save us, you can still save them."

His voice was trembling and hoarse.

I don't know whether it was because I was cold or because I was too nervous.

After hearing his words, Dongfeng sighed, with a trace of struggle in his eyes.

He shouted to Chang Yichang below:

"I'm so sorry. You also saw the sand and stones we used to seal the city. We can't open the gate now."

Chang Yichang pointed at the wall and shouted:

"You can use the rope to lower us down and hoist us up..."

When Dongfeng heard this suggestion, it seemed feasible.

However, the order personally issued by the minister is that once the gate of the buffer city is closed, no one or zombies can be allowed to enter.

Although he felt that these people were indeed pitiful, letting them in was a blatant violation of the minister's death order.
