Doomsday: Humanity shrinks 100 times

Chapter 43 Unexpected Guest
After they had thoroughly understood Zou Yunxin's special abilities, they ended the discussion.

Regarding the future application of this ability, Lu Yuning decided to first make a weapon to enhance the team's combat capability.

As for what to do, Lu Yuning hasn't figured it out yet, but this bomb is quite powerful, so he can make a few first, just in case.

A lot of rust was removed from the iron nails. Some of it was wasted in the previous experiment, but at least three or four more can be removed from the remaining ones.

There is no need to rush this matter, there are more important things at the moment.

The main purpose of this trip was to collect plastic, and nails and paper towels were unexpected gains.

With enough plastic, we can build sanitary facilities first.

The main reason is that the public sentiment is indeed quite urgent. The scenario is as follows:

"Yu Ning, the bathroom needs to be renovated. When I went there just now, I saw an ant. It's not ready yet..." Zhang Qian blushed and stammered about her experience. Her voice gradually became smaller and smaller.

"Well, we have enough materials. Let's start work today." Lu Yuning looked at Zhang Qian's expectant eyes and almost raised his hands to make a promise.

However, according to the previous plan, the sewage system must be completed first. This is considered infrastructure and subsequent expansion must be considered.

For this purpose, Lu Yuning discussed it in detail with Zhang Qian again.

At this time, Zhang Qian was holding a small wooden stick and writing and drawing on the ground.

"The total length of the sewage pipe is 60cm. I can't estimate the diameter at the moment, but it needs to be slightly wider, otherwise it might get clogged."

"Yeah." Lu Yuning wrote it down carefully.

"The vertical drainage pipe runs from top to bottom, with a vent at the top. The horizontal pipe is connected horizontally to the main drainage pipe, and the connections between the drainage pipes should use an oblique tee."

"Ah?" Lu Yuning was stunned when he heard the second sentence.

According to him, all he had to do was to build a main pipe and then connect each water inlet to the main pipe.

What about vertical pipes, horizontal pipes, and oblique tees? So professional?

"Oh, the oblique three-way connection can mainly prevent the blockage and accumulation of dirt." Seeing his strange look, Zhang Qian hurriedly added.

"Or, you can tell me how to do it." Lu Yuning was sweating profusely.

"Oh, that's fine. We just need to make a horizontal pipe temporarily. Now the sewage is mainly used for the bathroom. If there are new facilities later, we can connect them to the system in the same way." Zhang Qian nodded.

Under Zhang Qian's command, Lu Yuning finally knew what to do.

First, do as he thought, and build a supervisory line from top to bottom, straight to underground.

In fact, only this part has the heaviest workload. The other parts are all technical things. Just let Zhang Qian tell you how to do it. Lu Yuning felt a headache listening to it.

Therefore, if the sewage pipe is placed in the tree trunk, the workload is quite large, as the trunk needs to be dug through first, and it will be extremely difficult to maintain later.

Just put it on the tree trunk outside. Considering the aesthetics, you can cover it with wooden materials later.

The plan was finalized, and Lu Yuning completely transformed into a pipeline construction worker.

Wu Xiao was responsible for delivering materials to him, Zhang Qian was the construction director, and the remaining two had to be responsible for the surrounding safety and act as cheerleaders.

After a busy period of work, several people finally finished completing the entire sewage system before dark.

After this, Lu Yuning learned a lot of knowledge. For example, not only the joints are important, but the horizontal and vertical turning points of the pipes cannot be made into right angles. In short, according to Zhang Qian, this can prevent blockage.

The horizontal pipe has been extended to the bottom of the girls' dormitory, and all that's left to do is build the bathroom.

The next morning, Lu Yuning got up early.

I wanted to study the specific method of building a bathroom, but an unexpected guest suddenly came to visit.

A chipmunk that hadn't been seen for a day appeared in his sight. He thought it was Xu Qi, but he didn't expect that the person lying on the chipmunk's head was actually Xu Lele. Something happened to Xu Qi, this was Lu Yuning's first reaction.

He put down what he was doing and quickly went to meet him.

Xu Lele had been looking around for a while, obviously not knowing the specific residence of Lu Yuning and the others. However, when he saw Lu Yuning running over, his expression immediately lit up, and he jumped off the chipmunk's back slowly.

Her face was pale, and there were bloodshot eyes. She came straight to the point: "Brother Yu Ning, my sister is sick. She, she..."

She hesitated for a long time, and was a little anxious, but tears fell first.

Xu Qi is her only relative now. One can imagine how desperate this five or six-year-old child would be in doomsday if something happened to Xu Qi.

Lu Yuning stepped forward and rubbed her head to calm her down, then said softly, "Sister is sick. How is she now?"

"The situation is very serious now. My sister told me to come and find Brother Yuning if anything happens to her." With the comfort of Lu Yuning, Xu Lele gradually calmed down.

Lu Yuning thought for a few seconds. Although it was the end of the world and he should not be involved, he still couldn't bear to ignore the two sisters.

Then he said, "Lele, don't worry, let's go to the pavilion together."

After saying that, he ran back to the shelter to meet Wu Xiao and Zou Yunxin, then hesitated for a moment, knocked on the door of the girls' dormitory and called Zhang Xinyue.

Mainly considering that there may be some inconveniences, she knows more.

The others were not allowed to go with them. After all, they were not going there to fight, and having too many people would be useless.

When Zhang Xinyue heard that Xu Qi was in trouble, she looked worried and hurriedly followed the two of them to climb onto the chipmunk. The three of them and the chipmunk hurried to the pavilion.

"Brother Yuning, can you save my sister? My sister always tells me about you, saying you're very powerful. You must have a way, right?"

Xu Lele asked timidly on the way.

Before Lu Yuning could speak, Zhang Xinyue spoke first to comfort her:

"Of course, Brother Yuning is very good. You saw the tree hole we live in, right? It was all made by Brother Yuning, so don't worry. Tell me what happened first."

"Yeah, sister, I have a cold." After listening to Zhang Xinyue's words, Xu Lele became much more energetic and obviously had confidence in Lu Yuning.

"cold?"

Lu Yuning and Zhang Xinyue looked at each other and saw the confusion in each other's eyes.

Lu Yuning understood that he had a cold. It was probably because he caught a cold in the rain yesterday.

But from what Xu Lele said, Xu Qi was already in critical condition.

Otherwise, Xu Lele wouldn't have sneaked out.

"How can a cold be so serious?" Zhang Xinyue was a little confused and whispered to Lu Yuning.

"It's possible. Now that the human body has shrunk so much, the symptoms may be more severe. Especially if there is a fever, it may be more terrifying." Lu Yuning said solemnly.

"fever."
