Chapter 675 The sewer is done, causality theory [seeking monthly ticket for subscription]

The production of chemical fertilizers is not difficult for Anya, a master's student majoring in agriculture.

However, the preparation of pesticides requires more professional chemical knowledge, so she came here to find Bai Jie.

Bai Jie, Anya, Meng Yu and others took a gamble and came outside the Da Zhangshu Base to ask for help when they were about to freeze to death and starve to death in the previous winter.

It was a coincidence that they came here, and there happened to be Lao Lu in front of him who passed the test and joined the Dazhangshu base.

At that time, Li Yu was also thinking about the future ratio of men to women in the base.

Later, I heard Lao Lu say that these women are very talented, and they all came from Jiefang City.

In addition, my aunt and second aunt came forward and said that when they were in Jiefang City, they also received little care from Bai Jie and the others.

This world is very wonderful, planting a small cause often yields a good fruit.

Bodhisattvas fear causes, while mortals fear consequences.

Li Yu's experience in the last days made him not like to have too much relationship with others.

But my aunt, second uncle and others have received their favor, so they have to pay it back.

This is Li Yu's eschatological principle: repay kindness with kindness, and revenge with hatred; if someone gives me one point, I will pay him back three points;

The intention was to save their lives, but they did not expect that the arrival of these people greatly enhanced the soft power of the Dazhangshu Base.

Agronomy, chemistry, medicine and a little poem have brought great benefits to the Dazhangshu base.

If they hadn't met Xiaoshi, maybe Lao Luo and the others wouldn't have joined, and they wouldn't have told Li Yu where the tanks and mortars were...

Without Anya, it would be difficult to establish such a large-scale plantation with high yields, and it would also be difficult to build an underground planting base. Without stable food output, it would be impossible to support the expansion and cooperation model of the Da Zhangshu Base...

As for Bai Jie, Anya, and the others, because of Li Yu's rescue, because they pulled them out of that utter despair, their gratitude is beyond words.

Loyalty to Li Yu is directly boosted!

Especially after coming in, the development base is such a humane place, they are even more reluctant to leave.

At the beginning, they were worried that a place with such a strong human touch would not be able to adapt to this cruel end of the world.

Later, they realized that what they thought was too simple!

Face the enemy decisively and ruthlessly! Even cruel to the point of being a little perverted.

But when they saw this, they didn't feel disgusted, but became more fond of the big camphor tree base.

This kind of cruelty to the enemy gave them a sense of security, and Bai Jie fell in love with Li Yu beyond measure.

And when they faced Li Yu, Li Yu showed gentleness like a spring breeze. This strong sense of conflict and contrast made them a little confused, and then they cherished it.

After they understood, they realized that Li Yu regarded them as his own.

Tough on the outside, soft on the inside.

It wasn't until much later that I realized that what Li Yu said when he stretched out his hand to hold their hands was true: "If you join us, you will become a family."

………

On the cliff watch room.

Shang Xueer and Song Qi were on the wall, watching Li Hang and others driving slowly past.

Li Yu looked at the vehicles passing through the pine trees, threw the cigarette butts to the ground, and then stamped them out with -.

"Are they all here?" Li Yu asked when he saw a refined iron railing on the car, dragging some PVC casings.

Li Hang said: "No, I have moved this one here for now. Uncle Qin and the others are making other ones and they will be done soon. I will go back and move them here later."

"Yes." Li Yu nodded slightly, indicating that it was okay.

He Chao and He Bing, who came with Li Hang, put down the iron railings and PVC casings together.

Lao Xie quickly went over to help and carried these things to the car.

Ten minutes later, everyone moved their things out of the car.

Li Hang walked back to the car, turned to Li Yu and said, "Brother, I'll go back and transport the remaining iron railings first."

Li Yu waved and let him go.

Immediately, he said to the people next to him: "Let's get started and transport these things down quickly. Lao Lu and the others are waiting below."

Then he notified Lao Lu and Xu Zhen below that they would be ready to respond at any time.

Lao Xie and others tied the iron railings with thick ropes, and slowly lowered the iron railings with huge rocks as a barrier.

soon.

Lao Lu and the others saw the iron railings, then stretched out their hands to take them, followed by the PVV-C casings, and put them down one by one.

Watching everyone doing things in an orderly manner, Li Yu also looked at the situation around the cliff.

Just while waiting for Li Hang and the others, Lao Xie took a telescope and saw some movement in the woods next to the small mooring under the cliff.

But in the end I realized it was a bird, so I didn’t care.

But Li Yu still looked at the surrounding situation cautiously. Although zombies rarely appeared during the day, they could still be seen occasionally.

Everyone moved very neatly, and they transported the iron railings and other things to the bottom in less than 5 minutes.

………

sewer.

After Lao Lu, Xu Zhen and others took over the iron railings, they immediately began to install and carry them.

Due to the space of the sewer, only two people can barely stand side by side, so Lao Lu held the railing, and Xu Zhen installed it.

The sound of spot welding, accompanied by the strong light of electric welding, made Lao Lu turn his head to avoid damage to his eyes.

Xu Zhen, wearing a welding helmet, welded carefully, then fixed the PVC casing in a special way and pulled the line connection to the back.

Wang Cheng, who came down together, finished the PVC casing and lines bit by bit. The lines led directly to the well in the inner city, and then went up...

Time passed bit by bit.

Li Hang successively transported several other iron railings and PVC casings.

After Xu Zhen welded the iron railing, Wangzi pushed it and it was very stable!

I looked at the plug-in board protected by waterproof material. This plug-in board can control the opening and closing of the iron railing.

"Wangcheng, is the line connected?" Xu Zhen shouted towards the back in the sewer.

"Okay, it's already connected to the top and can be turned on at any time."

Their voices echoed in the long passage.

"Let's drive it and see if it works!"

"Okay." Xu Zhen stood down the well and shouted to Ding Jiu above the well: "Ding workers, turn on the electric switch and see if the iron railings open and close smoothly."

Ding Jiu then said: "Okay, I'll start."

He raised his hand and turned on the electricity introduced from the inner city.

Xu Zhen and Lao Lu pushed back slightly and looked at the iron railing.

This iron railing is much heavier than the original one, and it is made of waterproof material and is stronger.

boom--

Power is transmitted, and the iron railings slowly open outwards.

This iron railing cannot be opened inward, but can be opened outward to facilitate the discharge of sedimented sediment and garbage inside.

"It's done!" Xu Zhen shouted towards the inside again: "Turn it off and try."

Ding Jiu immediately lifted the switch again.

On the edge of the cliff, the iron railings of the sewer slowly closed!

Xu Zhen checked and tested several more times, and finally the iron railing was completed!
