Oil City.

Workers in the buffer city continue to install container sentry towers and ultraviolet lights.

The snow is getting heavier and heavier.

Zhang Rufeng and others outside the buffer city wall were shivering from the cold.

But they cannot retreat yet. They must wait until the container towers and ultraviolet lights on the fence are installed before they can return to the city.

Two hours later.

The snow showed no sign of stopping, and the ground was already completely white.

In the snow, there are still sporadic survivors coming.

Zhang Rufeng couldn't bear it anymore in the snow, so he hid in the car and picked up the walkie-talkie to contact Xie Changshan to ask:

"Xie Changshan, tell me how long it will take!"

Xie Changshan was so busy that he replied after a while:

"Two hours, give me another two hours, and the sentry tower and ultraviolet lights will be installed!"

"Damn it, it will be almost dark in two hours!" Zhang Rufeng complained.

Xie Changshan quickly explained:

"Captain Zhang, there is nothing I can do about it. I have installed it as quickly as possible. You and your brothers can hold on for another two hours, just two hours."

"Okay."

Zhang Rufeng stuffed the walkie-talkie back into his pocket, put on the headset, buckled on the windproof mask, and walked out of the car.

As soon as he stepped out of the car, snowflakes fell on his head.

He started up and stood by the car with the gun in hand.

In the snow, these guards from the Civil Armed Forces Division were like a long human-shaped wall, protecting the buffer city behind them.

.......

In the trading market.

Workers braved heavy snow to lay heating pipes in Area C of the residential area.

Now all the rooms in Area A, Area B and even Area C are heated.

The room with the heating on was as warm as spring. The survivors in the room without the heating could only wrap themselves up tightly in quilts, huddle in bed and watch the snow falling outside.

Three hours after it snowed, the temperature dropped again.

It reached minus five or six degrees Celsius with a slight breeze.

After it snowed for several hours, most of the survivors, except for the construction workers, returned to the residential buildings.

The number of people in the business district suddenly decreased.

Only outside the No. 2 store, there was a long queue. These survivors came here to buy tortillas.

Trading market industrial area, white mist is steaming.

The entire trading market was much quieter than usual.

In oil city.

Uncle San was sitting in the office making hot tea. The heat from the radiator next to him made the whole office feel as warm as spring.

call--

The third uncle took a sip of hot tea and looked out the window at the falling snow.

He had contacted Xie Changshan just now, and it would take another two hours to complete the buffer city.

But it is already two o'clock in the afternoon, and it will be dark in two hours.

Tuk Tuk——

There was a knock on the door outside.

"Come in." Third uncle said in a low voice.

I saw Lao Huang and Ju Tianrui walking in together.

Ju Tianrui turned around and closed the door behind him, then said to his third uncle:

"Now, 2,000 buffer city wall guards have been recruited, and I have temporarily placed them in the temporary shelter in Building 6, North District.

We are now distributing cold weapons and windproof and warm clothing to them. I will let them go up when the mission to Changshan is about to end."

"Where is the team that is supporting Zhang Rufeng and the others? Who did you send?" asked the third uncle.

Ju Tianrui quickly said:

"Dongfeng and Zhang Tianfu, they are also ready and can go up the wall at any time."

"Um."

The third uncle nodded slightly, "Okay, I understand, then just proceed according to the original plan."

While Zhang Rufeng and the others were retreating back to the buffer city, someone also needed to be on duty on the fence for protection.

Otherwise, Zhang Ru and the others would not be able to retreat while guarding the buffer city wall.

After seeing what Ju Tianrui said, Lao Huang said:

"Minister, I would like to ask when the construction of the greenhouses in the buffer city will start?"

"If it's going to be built, will it have to be re-recruited? Or will it be selected from existing workers?"

The third uncle thought for a moment and said:

"Let's talk about the greenhouse tomorrow. We'll wait until the buffer city wall stabilizes."

"If you want to build a greenhouse, don't recruit again for the time being. You can go back and let Xie Changshan and the others select from the existing workers based on the number of labor required to build the greenhouse."

"OK."

........

Northern Territory.

The snow is like a swarm of wildly dancing butterflies, spinning wantonly over the ruins, mercilessly devouring the world.

The towering wall stands alone, like a desperate line of defense, guarding the fortress.

Above the wall, the iron-gray city wall was covered with snow, making it look even heavier, as if it was also filled with the sadness and heaviness of this land.

The guards shivered in the cold, like kites that had been stripped of all their strength, allowing themselves to be ravaged by the wind and snow.

Every time they breathed in, the frosty air condensed into ice shards on the tips of their noses, and the desire for warmth shone in everyone's eyes.

Changing of guard.

The person who was relieved of duty quickly ran into the guard tower.

Inside the sentry tower, the heat was steaming, and a layer of fine water droplets condensed on the walls.

That is caused by the large temperature difference between inside and outside.

Under the corner, several zombie corpses lay quietly, gradually buried by the heavy snow.

Tap tap tap——

Several wall-climbing zombies jumped under the corner of the wall, struggling to dig up the snow, turning over the thin layer of snow, and biting the zombies killed by the guards below.

When the wall-climbing zombies eat, their sharp teeth tear into the carrion of their kind, chewing the bones and making a clicking sound.

They quickly devoured the corpses of their kind and climbed up the wall.

But after crawling for more than ten meters, he was driven back by the ultraviolet light shining down from above.

When these wall-climbing zombies encounter ultraviolet lights, they are like mice encountering cats, and they flee down in a hurry.

Lying on all fours under the city wall, he raised his head and looked at the humans on the wall.

Seemingly unwilling, they climbed up the wall again, crawled to a height of seven or eight meters, and then ran parallel to both sides.

They are like geckos, wandering on the wall.

However, when they try to continue climbing up, they are exposed to ultraviolet light.

That is to say, it is snowing now, which reduces the distance of ultraviolet light.

Otherwise, these zombies would have no chance to climb up the wall. They might be exposed to ultraviolet light just by standing under the wall.

In a greenhouse in the northern outer city.

Green crops, full of vitality.

It was completely opposite to the ice and snow outside and the freezing temperature.

Huo Guanghua wore gloves and took a small shovel to dig up the cultivated vegetable seedlings and put them aside.

The cabbage seedlings they planted grew together after sowing.
