"Found it!" Li Hang saw a label behind a truss.

He quickly ran in, and Second Uncle and the others hurriedly followed.

After rummaging around, they finally found the PVC-C conduit materials, which were piled up on the 6-meter truss.

Li Hang said to Second Uncle and the others behind him, "This is it, let's take it to the Second Outer City. I'll go look for some other needed materials."

Second Uncle and the others came with small carts, piled these PVC-C conduits on them, and then transported them to the Second Outer City.

At this time, in the Second Outer City, Zhou Ran and others had already constructed the iron fence and control system according to the dimensions, and the next step was to manufacture them.

There were also some circuit boards and other things in this workshop that could be used directly, so everyone started making them directly.

......

In the Inner City, Ding Jiu, Old Lv, and others cleaned up the mud and rubbish in the sewers.

Li Yu sat on the sewer cover, touching the turtle that Old Lv brought up from the sewer.

"Old turtle, what were you doing down there?" Li Yu tapped the turtle shell with his middle finger.

The turtle stuck out its head and stared blankly at Li Yu.

Li Yu withdrew his hand, looked up, and said slightly sentimentally, "Stay put, don't wander around, the storm is coming..."

At this moment, the sun was shining brightly, with no sign of heavy rain or floods.

Because of this, many survivors let their guard down, but Li Yu knew, when disaster strikes, it would be overwhelming.

...

Time ticked away.

Three or four hours later.

At this time, Lao Xie and others also brought in several big pine trees from the edge of the cliff with a truck.

The average diameter of general pine trees is only about 20 centimeters; the diameter of these pine trees was 45 centimeters, having grown for at least seventy years.

Li Yu, holding the big turtle, carried it to the residential area.

Such a Chinese softshell turtle, with a diameter of 50 centimeters and weighing dozens of pounds, must have lived for several decades.

This thing is great to keep at home.

The residential area also had a wall, but the wall wasn't high. Li Yu put this softshell turtle at the villa's door and let it choose a place to stay.

"Director Li, we've cleaned up here and can install the wiring system and iron fences at any time." Xu Zhen's voice came through the walkie-talkie.

"Good!" Li Yu immediately picked up the walkie-talkie to respond.

On the other side.

Lao Zhou was wearing a welding helmet, using carbon steel electrodes to weld the iron fence.

The plug board for controlling the line was fully enclosed with waterproof materials, and the entire line was covered with waterproof and heat-resistant materials.

In addition, the electrical lines were protected with an outer wrapping of PVC-C conduits.

At this moment, Li Yu's voice came through the walkie-talkie, "Xiao Hang, how is the progress over there? Old Lv and the others have finished here and can install it at any time."

Li Hang looked at Old Qin, who pointed to a finished iron fence and conduit, "Take this over for installation first, and bring the rest over later."

Li Hang nodded repeatedly, "Okay."

He then informed Li Yu, who asked Li Hang, He Chao, and Zhou Ran to take these things around the Big Camphor Tree Base to the cliffside.

Soon, Li Hang and the others drove the cars, transporting these items to the top of the cliff.

Li Yu, Ding Jiu, and a few others were now beside the boulder, watching as they slowly drove over.

In the sewer, Old Lv, Xu Zhen, and others waited below.

......

The sun slowly descended to the west, it was now 4 PM, and it would set in another hour and a half.

In the Big Camphor Tree Base, the wind blowing through the rice fields emitted a fragrant aroma.

Meanwhile, in the Research Room, a discussion was underway.

Bai Jie helplessly said to An Ya:

"Xiao Ya, you want fertilizer.

Just use organic fertilizer, I'll give you five methods.

First, ammonium carbonate fertilizer:

Method: 100 pounds of fresh cow manure (chicken or sheep manure works too), 1 pound of soybean powder, 8 pounds of calcium sulfate (gypsum powder).

Second: ammonium sulfate fertilizer.

Use 50 pounds of human excrement, 5 pounds of calcium sulfate (gypsum powder), add 20 pounds of water, stir and mix well, seal it for 10-15 days. This fertilizer is mainly used as topdressing, applied in furrows when needed.

Even if you want to use compound fertilizer, it's also simple.

150 pounds of human excrement, 100 pounds of superphosphate, mixed and piled, covered with mud and soil, generally ready in 7-10 days. Fertilizer made by this method can be used as both base fertilizer and topdressing. Due to its strong efficacy, it's best not to use it to soak seeds to avoid affecting germination rates.

......

Bai Jie finished in one breath and couldn't understand why An Ya didn't know this knowledge.

Sure enough.

"I know what you're saying, but I came to you for pesticides. Last time, the crops still had some insects. To be safe, can you make some basic pesticides for me?" An Ya said.

"Should've said so earlier..." Bai Jie mumbled, momentarily stunned.

......
