Desperate Night.

Chapter 159 Pollution 159
Ding, ding, ding.

The knocking sounds that continued to spread in the camp added a touch of liveliness to the entire silent forest.

These days, it seems that the high-risk black disaster has been repelled, the red value concentration of the surrounding air environment has also dropped a bit, and there are fewer strange shadows. It seems that the red value concentration cannot support the revival of so many black disasters in one breath.

Peace and tranquility suddenly descended upon the Black Wind Camp.

Yu Hong followed the edge of his cave and chiseled out large square stones more than one meter long and wide from the mountain wall in the direction away from him.

These stones are about 15 centimeters thick, not very regular and uniform, and weigh about half a ton.

But in front of Yu Hong, they were just ordinary small stones. He grabbed them with one hand, one on each side, and stacked them all in the center of the camp.

In order to avoid the underground formation structure, Lao Zhou and Lao Li had already cooperated to dig the foundation in advance, revealing the black wind formation underneath.

At this time, the two were squatting beside the large foundation pit, observing the structure of the Black Wind Formation buried underground.

Some silver-gray networks like plant roots were revealed in the black soil pit.

These networks are spread all over the pit, sparse in some places and dense in others, as if they were really grown naturally. However, the linear structure of the network is made of materials similar to metal or rock, and it is obviously a man-made product.

After the two saw the base of the Black Wind Protection Formation, they had been squatting here discussing it for a while.

This man-made product aroused great interest in them.

Seeing Yu Hong coming, the two stood up.

"Boss, we have almost enough stone for the stone fortress." Li Runshan pointed to a large area where hundreds of square rocks were piled up.

"Then the stones need to be polished and leveled, and adhesives such as cement joint glue are needed."

"I can't do anything about the adhesive." Yu Hong shook his head.

"Then let's just use the dry masonry method." Old Li nodded. "The next project will be larger, but the dry masonry method cannot build a stone fort that is too large."

"It's okay, it will get better slowly." Yu Hong nodded.

After getting confirmation, Li Runshan took Lao Zhou with him, and the two began to measure data with tools.

Yu Hong didn't know these technical skills, so he stood further away. He looked at the outer courtyard in the distance, where Dr. Xu was playing on the swing with Nana.

A few days ago, at the request of his daughter, Mr. Li built a wooden frame in the yard, hung two ropes and tied wooden boards to it, and it became a super simple swing.

The whole process takes no more than twenty minutes.

This guy is really good at manual work. He works so quickly even with injuries.

Cough
Suddenly a slight cough was heard.

It’s Doctor Xu.

Yu Hong frowned and looked at Xu Ruoying who was pushing Aisina on the swing.

Her face turned pale, and she covered her mouth with one hand and kept coughing.

"The weather is getting colder, so we have to add more warming equipment. Otherwise, it will be troublesome if we get sick from the cold." Ding Shao walked closer and whispered.

She buried Yao Feiling outside the secondary safety zone, under the largest and thickest old tree, and then carved her name on the trunk as a tombstone.

After a few days of recovery, she can now walk slowly in the yard outside the camp.

But because he was not an official member, he could only continue to live in the wooden shed.

Warming equipment
Yu Hong actually already had some preliminary arrangements.

He didn't say anything, but looked at the entire inner courtyard of the camp.

'The water from the cooling of the nuclear power plant can be completely recycled, and the heat can be used to surround the camp to form a warm and constant temperature structure. However, the heat dissipation will eventually cause other black disasters. Once the stone fort is initially built, the insulation layer is applied, and the hidden symbols are installed, it should be fine.'

Hearing Dr. Xu's cough, he turned his gaze and looked towards the small cave No. 2 on the other side of the breeding house.

"We can first introduce cooling water into Cave No. 2 to ensure the temperature of the breeding box. Then bury it directly underground into the camp yard to ensure a basic temperature."

Mushrooms, cockroaches and lizards all require a certain temperature to grow. If it is too cold, the yield will drop sharply.

After all, neither cockroaches nor lizards are self-heating and homeothermic creatures.

This is what Yu Hong planned. In the past few days, he has completed the reinforcement of the radiation grenades, and Black Seal can also start a new reinforcement task.

After making up his mind, he looked at Ding Shao.

"How long will it take you to recover?"

"The medicine here is quite effective. It will be cured in about a week." Ding Shao said honestly.

Yu Hong glanced at her abdomen with a little surprise, and he didn't hold back when he kicked her.

It only takes a few weeks of rest to recover. Obviously, he once again confirmed that Ding Shao is a very good type among the enhanced humans.

"Okay, I'll prepare something for you then." He said in a deep voice.

The little stammerer's appearance is easy to recognize, so there is no problem with that. The main thing is that I am not sure where she is now.

"Okay." Ding Shao nodded. She also knew that the fact that she could stay in this camp for such a long time unconditionally was already a buffer time given by Yu Hong to allow her to recuperate.

If you delay any longer, you might really be kicked out.

After arranging the tasks, Yu Hong returned to the cave and closed the door.

He pressed one hand against the wall and closed his eyes.

'Reinforce the cave safe house and strengthen the drainage outlet of the nuclear power generator cooling water pipe into a mesh root structure in the direction of.' Yu Hong imagined in his mind that the cooling water pipe was bending, branching, and thinning into thinner water pipes.

The water pipes go deeper and deeper, covering the walls of the cave, as well as the cave of another breeding house No. 2 next to it and the open space underground in the inner courtyard outside.

"Should we strengthen the cave safe house?" Black Seal asked as expected. A black line flew out, and soon a dark red countdown appeared on the wall.

'16:42.'

The time is okay.

"Yes."

After confirming the start of the countdown, Yu Hong began to practice the Thunder Leg.

Cough cough cough.
There was another coughing sound coming from the yard outside, but this time it was not from Dr. Xu, but from Old Zhou.

Yu Hong frowned, feeling a sense of urgency.

He glanced at the detector beside him, which showed the temperature: 3 degrees.

'Once the temperature comes up, everything should be fine,' he thought.

Time passed slowly, and it was early the next morning.

The moment when the black seal enhancement ends.

More than ten centimeters underground in the entire inner courtyard camp, the soil suddenly blurred for a moment. The next moment, some neat black thin water pipes appeared.

Water pipes as thick as a little finger are evenly laid underground in the inner courtyard.

The cooling hot water from the nuclear power plant began to flow out continuously through the new pipes, radiating a large amount of heat into the cave and the inner courtyard camp.

Slowly, the temperature began to rise slightly.

Yu Hong walked to the door and looked outside through the viewing window.

After a while, Lao Li and the other people who were working on the construction site were the first to feel the warmth. Li Runshan's eyes lit up, as if he had thought of something, and hurried over.

"Boss? It seems to be getting warmer outside?" There was a hint of speculation in his expression.

"Yes, I did it. I used engineering machinery to work underground and laid some cooling water pipes to dissipate the heat from the nuclear motors and keep everyone warm." Yu Hong nodded in response.

"Construction robot!" Old Li's eyes lit up. "Can I..."

“No, it’s subject to wear and tear. We should try to do what we can ourselves. Otherwise, when the robot is worn out, it will be gone and it will be difficult to use it in the future.” Yu Hong made up a reason.

"Okay." Lao Li felt that it was really wise to follow Yu Hong. Listen, construction robots!

Too high-end!

In his entire life, he had only heard of this kind of high-tech gadget in the news from the Silver Tower.

Old Li passed the news to others, which immediately caused everyone to cheer.

The drop in temperature has become a problem that everyone is concerned about recently.

It was so cold that everyone was less and less willing to go out. They all stayed in the house, keeping warm by blocking the wind and covering themselves with blankets.

Now, the camp is gradually warming up and we don’t have to worry about getting sick from the cold anymore. We can come out and move around freely.

Now that such a big problem has been solved, there should be no problem in the future.

Yu Hong thinks so, and so does Lao Li.

But on the second and third day, everyone in the camp, except Yu Hong himself, started coughing.

"Something's wrong!"

Yu Hong had just condensed the sixth internal energy, and before he could feel happy, he was frowned by the continuous coughing.

He came out of the cave and walked on the inner courtyard, feeling that the temperature in the camp was noticeably higher.

"boss."

Li Runshan and Zhou Xueguan were discussing something under the lamppost. When they saw him come out, they hurried over.

"Boss, I'm afraid we're in trouble." Li Runshan said with a serious face. He immediately couldn't help but cough a few times.

"Isn't it a cold?" Yu Hong asked.

"No, it's purely pharyngitis. Doctor Xu concluded that it's probably an air problem." Li Runshan replied.

"Air. Is there an air purifier in the camp?" Yu Hong asked in a deep voice. Last time, Lao Li brought back so many small electrical appliances, and he let them divide them among themselves, and he didn't ask any questions.

"No, the core of that thing is to replace consumables. Without consumables, the machine alone is useless, so I didn't take it." Li Runshan felt a little regretful.

"Besides, we can't be in an isolated space right now. Even if we use an air purifier, we don't know if we can isolate the source of the coughing." Zhou Xueguan coughed and added.

".Old Li, let's speed up the construction of the stone fort. Once it's built, everyone can hide inside so that the air can be filtered. The premise is that this cough is really caused by the air." Yu Hong continued.

He suddenly felt very tired.

I originally thought that there was only the Black Disaster in this world, and as long as I kept getting stronger, I could keep it stable by resisting the Black Disaster. Now there is a problem with the air.
One layer after another.
He suddenly wondered what the future of humanity in this world would be like in such desperate environmental changes.

Just like this, just to live purely, you need to try your best.

"First, we need to determine what in the air is causing the cough. I'll test this," Yu Hong sighed.

"Oh," Lao Zhou sighed and said nothing more.

"After Doctor Xu used a breathing valve to filter the breath, the coughing was significantly relieved, so she was sure that there was some floating matter in the air that caused us to cough." Li Runshan said.

"Then use the breathing valves. I will check the others. Once confirmed, we will speed up the construction of the stone fortress together." Yu Hong nodded.
