The water mist is mixed with the mountain smoke, and the sky is nowhere to be seen.

A hazy fog swept over the sky and covered the sky.

After crossing Wuyi Mountain, we headed straight to the direction of Dazhangshu Base.

Heavy fog refers to a weather phenomenon in which water vapor in the air condenses to form a large number of water droplets, resulting in a significant reduction in visibility.

Therefore, in some places with relatively high altitudes, the temperature is lower and thin rainwater drips down.

A mighty heavy fog came.

.....

Big camphor tree base.

Inner city.

Li Yu was sitting on the sofa on the balcony, smoking a cigarette, frowning.

A whole day has passed since the time of heavy fog in his previous life.

But there has never been heavy fog at Da Zhangshu Base.

However, Li Yu also had some guesses. In his previous life, he was closer to the ocean, but now he is staying at the Da Zhangshu Base and is farther from the sea.

But even with such speculation, Li Yu always felt uneasy.

If the fog doesn't come, it means that things have changed in his life.

The heavy fog is coming, which is also a great challenge for the Da Zhangshu Base.

In this anxious mood, there was a sound of footsteps behind me.

Hearing the sound of footsteps, Li Yu knew who was behind him.

She suppressed her inner anxiety, put a smile on her face, slowly turned her head and said, "Are you awake?"

With a happy smile on her face, Yutong came over and sat next to Li Yu, then put Li Yu's arm on her shoulders.

"What are you thinking about?" Yutong raised her head and looked up at Li Yu and asked.

Li Yu was stunned for a moment, then said: "I'm not thinking about anything, I'm in a daze."

"Liar."

Yutong looked at Li Yu and said, "A woman's sense of smell is very sensitive. I feel that you are a little uneasy. What's wrong?"

When Li Yu heard what Yutong said, he smiled and said:

"Didn't I tell you a few days ago about Qingyuan's speculation about the foggy natural disaster? This has never happened, and I feel uneasy." Li Yu said.

Yutong thought for a while and couldn't help but said:

"Is there a possibility that what Qingyuan said is wrong? After all, there is no scientific basis for this."

Li Yugang wanted to refute, but he stopped.

He said, "What you said makes sense."

He stood up slowly, helped Yutong up and said:

"Didn't you say yesterday that it was too boring to stay in the room? Come on, I'll take you out for a walk."

After Li Yu finished speaking, he actually didn't say the second half of the sentence.

It's possible that there will be heavy fog soon. When the fog starts, you won't be able to see anything outside.

Yutong's eyes lit up when she heard that she could go out for a walk.

So he walked quickly, walked to the side, picked up his coat, stretched out his right hand and said: "Let's go!"

Li Yu smiled, took Yutong's hand, and walked downstairs.

Half past two in the afternoon.

The sun is just right, not too warm or too cold.

Li Yu and Yutong were walking on the sidewalk in the inner city. There were solar street lights on the left and right sides of the sidewalk.

In the chemical factory near the Fourth Outer City, Kong Shuang rubbed his eyebrows and said to Xiaolan: "We use membrane separation to produce nitrogen, and pressure is the most important..."

Xiaolan nodded and asked: "Sister Kong, the air temperature and electricity are both good now. What else needs attention? I'll write it down."

As she spoke, she took out a small notebook and a pen from her pocket and prepared to take notes.

Kong Shuang thought for a while and said:

"First of all, the clean membrane separator over there.

You must know that the membrane separator is a core component and needs to be cleaned regularly. When cleaning, you first need to remove the membrane separator, rinse it with clean water, then wipe it dry with clean gauze, and then blow it dry with clean air.

Second, check the pressure gauge: Regularly check whether the reading of the pressure gauge is normal. If it is not normal, it needs to be adjusted or replaced.

Third, check the air path: Regularly check whether the air path is smooth. If there is any blockage, it needs to be cleaned in time.

....."

After finishing speaking, she looked at the filled liquid nitrogen and frowned slightly.

"I don't know why the city lord insists on producing so much liquid nitrogen. Although the liquid nitrogen is originally made of air, it consumes too much power to produce it non-stop. Alas..."

Kong Shuang didn't know about the zombie generator until now.

Although Lao Dong knew about it, his second uncle and Li Yu had repeatedly stressed to him not to let anyone know about it.

Old Dong also understands that the more you know, the more dangerous it will be, so he has never told Kong Shuang about this matter until now.

Kong Shuang has been working at the Da Zhangshu Base for some time and has some knowledge of the base, but she has never been able to understand one thing. The energy consumption of the Da Zhangshu Base is very large, but it does not rely on firepower, steam, or even oil to generate electricity.

Just relying on the solar panels in the base, she estimated that they would not be able to support the base's electricity consumption.

However, no matter how many doubts she had in her heart, she did not ask any questions.

Whatever the base wants her to know, she will know sooner or later.

She should not let her know, but she found a way to figure it out. On the contrary, it may not be a good thing, but a bad thing.

Curiosity killed the cat.

Just at this time.

A dozen men pushing carts walked in from outside.

"Captain Lu." Kong Shuang said quickly after seeing him.

Lao Lu nodded, looked at the latest batch of liquid nitrogen produced, and said, "These are all filled, right? The city lord asked me to put this liquid nitrogen on the wall as soon as possible this morning."

Kong Shuang nodded and said, "Yes, it's all filled."

As she said that, she looked at Lao Lu and reminded:

"By the way, you must pay attention."

"Liquid nitrogen absorbs a lot of heat when it vaporizes. Contact with skin can cause frostbite. Protective gloves must be worn when handling liquid nitrogen."

Lao Lu smiled and raised his hand and said, "Don't worry, we have all put them on."

Kong Shuang felt slightly reassured when she saw their protective gloves.

Then he said: "Okay, you can move out."

Later.

Lao Lu then led people forward, loaded the tanks containing liquid nitrogen onto the trolley one by one, and then pushed the trolley towards the wall.

This chapter is not over, please click on the next page to continue reading! On the wall.

On average, every thirty meters away, there are several liquid nitrogen tanks and a simple spray device.

"Huh - Captain, when are you going to use this thing?" After bringing up the liquid nitrogen, a team member asked, wiping his sweat.

Although Lao Lu knew that it was because the city lord was considering the natural disaster of heavy fog, he didn't quite understand the relationship between liquid nitrogen and heavy fog.

However, even if he did not understand the city lord's orders, he would still carry them out.

Li Yu has led the people in the base to resist natural disasters time and time again, and has completely convinced them.

"Don't worry about it, just do it!" Lao Lu didn't know how to explain it, so he said impatiently.

After hearing this, the team members shook their shoulders and stopped asking, and quickly pushed the liquid nitrogen tank placed on the wall to the edge of the wall.

"Captain, when our shift is over, let's go to the recreation room and play two strokes?" Xiao Wang, a member of the team standing nearby, asked.

Long before the end of the world, Li Yu had stocked up on some indoor and outdoor entertainment supplies, including billiards, table tennis, basketballs...

A gymnasium was even built in the inner city just to allow the people in the base to relax after being busy.

In recent years, natural disasters have continued, making many people in the base unable to go out, so they can only rely on these to pass the time.

When Lao Lu heard this, he glanced at Xiao Wu and said:

"Okay, do your duty well and go back after you're done."

Immediately afterwards.
