Apocalypse Rebirth: 3000 million won at the beginning

Chapter 674 Waterproof Materials and Fertilizers

The wall on one side of the cliff is [-] meters away from the cliff.

Although the distance in the middle is only [-] meters, there are still some trees, but because of natural disasters, most of the trees above are dead.Only a row of thicker trees remained.

Afternoon sun, with warmth.

The breeze blows slowly, blowing off the pine needles on the pine tree, rustling and falling.

These stout pine trees have survived the severe cold and heat, and have rooted deep into the ground.

At noon, the temperature reached more than [-] degrees, making people feel that winter has passed.

The temperature of the sun shines on people's bodies, and the breeze is not dry, making people feel very comfortable.

Song Qi and Shang Xueer on the fence saw Li Yu and the others get off the car, waved their hands, and shouted to Li Yu and the others: "Mr. Li, what are you going to do?"

Li Yu covered the sun with his hands, raised his head to see the two people on the fence, and said, "Repair the sewer, you guys watch from above, and if you find zombies, let us know."

"Okay, then you must pay attention to safety!" Shang Xueer shouted.

Li Yu beckoned to show that he knew.

Immediately, Lao Xie and the others carried the rope on their backs and walked towards the cliff.

Because of the trees ahead, the pickup truck could not reach the edge of the cliff directly, and they had to walk a short distance.

Several people carried guns and spears on their backs, walked through the row of pine trees, and soon reached the edge of the cliff.

Lao Xie carefully stood on the edge of the cliff, estimated the position, and then let the rope down.

Wang Cheng tied the rope to a huge rock six or seven meters away from the cliff.

The rope hangs down.

Li Yu took out the walkie-talkie and said to the two people in the sewer: "Lao Lu, the rope is down, did you see it?"

Lao Lu was stuck on the iron railing, saw the rope hanging down three meters away, and fed back through the walkie-talkie: "Pull another three meters to the right, the current position is wrong, we can't reach it!"

Hearing this, Li Yu said to Lao Xie: "Pull it to the right for three meters, and it didn't align with the position below."

"Okay." Lao Xie pulled the rope and pulled it over.

"Yes, yes, stop." Lao Lu, who was below, saw the rope floating past the iron railing, and quickly stretched out his hand to pull the rope.

Li Yu hurriedly told Lao Xie to stop.

Lao Lu took the rope and tied it to the iron railing, which was very firm.

Then he stepped back and said to Xu Zhen: "Okay, old Xu, cut and cut this iron railing, and they will pull it up."

Xu Zhen took the cutting machine, stepped forward, and started cutting.

beep-

The cutting sound was sharp and loud.

Lao Xie heard the sound of cutting from above, and immediately let go of the rope to prevent the iron railing from being cut later, and the gravity falling would bring him down.

Xu Zhen cut for 10 minutes, and finally cut off the welded steel plates on both sides of the iron railing.

But he held on to the iron railing, and the iron railing did not fall down.

Turning his head to Lao Lu, he said, "Lao Lu, remind them that we have cut the iron railing and let them prepare for the response on it!"

Lao Lu immediately took out the walkie-talkie.

After receiving their news, Lao Xie, Wang Cheng and the others stood beside the boulder.

"Okay. Push it down." Li Yu contacted the two people below through the walkie-talkie.

Immediately, Xu Zhen pushed the iron railing outside forcefully.

Bang!

The iron railing fell to the cliff, but soon because it was tied with a rope, the rope pulled the iron railing.

Hit the cliff.

Lao Xie and the others on the cliff saw that the rope was quickly tightened, so they walked over slowly.

Four or five people grabbed the rope and pulled it up vigorously.

The iron railing is still a bit heavy, but fortunately it is not high, otherwise it would be troublesome to pull it up.

A few minutes later, Li Yu looked at the row of pine trees behind him, and said, "Saw off those pine trees later, and drive the car over to pull them, or it will take too much effort. Later, Xiaohang and the others The newly completed iron railings are estimated to be heavier, and we cannot pull them alone."

Lao Xie wiped off his sweat, nodded vigorously and said, "Sure, there is a chainsaw in the car, and I will saw it now."

Lao Xie called two people and walked towards the pickup truck.

Only a few tens of meters away, Li Yu and the others sat on the boulder, smoking, watching Lao Xie and the others drive the car under the pine tree and saw off the few pine trees in the middle.

As the few pine trees in the middle were sawed off, the field of vision became much wider.

Lao Xie and the two drove over.

When they drove over, everyone worked together to carry the iron railings onto the car.

Immediately, several people used the same method to lift up the iron railings of the other drainage outlets.

Lao Lu and Xu Zhen in the sewer asked the people in the city to move down the cleaning equipment, and then began to clean up the silt and garbage in the sewer.

Xu Zhen climbed up from the sewer, gave Li Hang the photos and videos just taken, and gave Li Hang the measured details of the size of the iron railings, and asked Li Hang to make according to this size.

When Xu Zhen and the others climbed up from the sewer, Li Yu and the others also drove a pickup truck back to the inner city from outside the fence.

After receiving Xu Zhen's size requirements and video photos, Li Hang rushed to the small factory in the second outer city without stopping.

At this time, Li Yu got out of the car and saw that Xu Zhen was the only one here, and asked, "Where are Ding Jiu and Lao Lu? Are they still down here?"

Xu Zhen nodded and said, "Yes, they are still below, using cleaning equipment to clean up the sediment and sludge below."

"Well, okay." Li Yu nodded slightly.

Then he turned his head and said to Lao Xie behind him, "Don't waste the trees you sawed off just now, go out and pull those trees back."

Those pine trees are relatively strong, and it is very rare to be able to survive such a severe cold and hot environment.

Lao Xie nodded, took two people into the car, and then drove out of the base.

In the sewer, Ding Jiu and Lao Lu are cleaning up the sediment and garbage in the sewer.

It was the first time since the outbreak of the end of the world that they cleaned up the sand inside. Ding Jiu scooped up the sand with a shovel. Sweat dripped on his arms, and he took off the mask.

The smell is too strong here, but it is too stuffy to wear a mask all the time, so I had to take it off to breathe a sigh of relief.

The second outer city.

Li Hang, Zhou Ran, Lao Qin and others were sitting in a circle, discussing issues such as iron fences and control lines.

"If you want to put the control lines in the sewer, they will definitely be submerged in water, and the wires must be completely covered with materials. I remember some PVC-C casings that Zhu Xiao bought from the next city before. I don't know where to put it."

He Bing listened carefully to Li Hang's request and said after looking at the pictures on the iPad.

Under normal circumstances, whether it is cooperative personnel or non-staff personnel, some materials and equipment brought in will be transported to the inner city.

After a long time, more and more things have been hoarded. Some things that are more precious in Li Yu's view are stored in the cold-proof and heat-insulated underground warehouse.

For more things, a relatively large factory building was built in the inner city, and then all the things collected from the outside were put into it.

In fact, the cooperators sometimes exchange things that are not on the list, and sometimes Li Yu and the others think that they may be able to use materials, and they will also exchange them for food.

Since the cooperation model was launched, this factory building, which is stockpiled with various materials, has been expanded many times.

The second uncle got the food processing factory, so he found an area for them to use from the factory building where the supplies were stored.

Zhou Ran also nodded and said:
"Well, He Bing is right. If you want to bury this line in the sewer, PVC-C casing is fine. And this material has many advantages.

1. Good heat resistance: PVC-C hot and cold water pipes have good heat resistance and can be used in high temperature environments. They were often used in chemical plants, oil refineries and other fields before.

2. Strong corrosion resistance: It has excellent corrosion resistance and can be used in acid, alkali, salt and other chemical environments.

3. High strength: It has high strength, can withstand greater pressure and tensile force, and is suitable for occasions under pressure.

In addition, this material is very light, and it is easy and fast to carry it. "

When Li Hang heard this, he got up immediately and said to everyone, "I'll go find it right away. You guys have to find a way to make a controllable iron railing. My brother said it should be stronger. At least stronger than before!"

After speaking, he ran to the inner city. On the way, he happened to meet Erjiu and Li Zhengping and others, so he briefly talked about it, and dragged them to look for PVC-C casings.

When the second uncle heard about this matter, Li Yu took it very seriously and became serious.

Immediately said: "Okay, I'll go with you, Zhengping, I'll talk to the factory later, don't produce it for now, let's go find this material together."

His nephew held an unusual position in his heart.

From the beginning when the outbreak broke out, Li Yu began to plan for the farmhouse and let them come back.

Later, with his wife and children, he returned with difficulty for thousands of miles, and was on the verge of death in Jiefang City.

If the little girl hadn't just seen Li Yu and the others outside Jiefang City, she would have died long ago.

After arriving at Dazhangshu Base, after waking up from a coma, he found that his parents were still there, his elder brother and elder sister were all there!

When he was in Jiefang City, he was on the verge of life and death and starvation; after waking up, he once suspected that he was dreaming, but the facts told him that it was true.

Since then, he has achieved [-]% trust in this nephew.

Because he has seen the cruelty outside, and because he has been robbed, injured, and his relatives died with his own eyes, he knows how right it is for Li Yu to act ruthlessly.

Although in his opinion, there were many things in Xiaoyu that he couldn't understand, but he didn't ask.

He cherishes everything he has now, so he will listen to Li Yu very much.

Not only him, but basically all of Li Yu's elders did not put on airs in front of him.

At the beginning, Li Yu's grandfather and grandfather set the tone: here, Li Yu is the master!
.........

Seeing how enthusiastic the second uncle was, Li Hang didn't think too much, so he ran to the warehouse with them.

Li Hang used to tinker with messy things before, and a few days ago, he and He Bing made zombie generators. He came here to search for the materials needed, so he is more familiar with this place.

Standing in front of this wide stocking factory, he thought for two seconds, and then walked towards the factory door in the middle to the right.

slam-la-

He opened the shutter door, ran in, and opened a closed door.

In order to protect various materials and equipment inside, two doors are set up.

After entering, there is a hall inside, and there are some trusses inside. Li Hang searched each truss, and there are some labels on the trusses, and the labels are the classification words of some things behind.

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

He ran in quickly, and the second uncle and others hurriedly followed.

After a bit of rummaging, I finally found the PVC-C casing material that filled the 6m trusses.

Li Hang said to the second uncle and others behind him: "That's all, let's take it to the Second Outer City. I'll find other materials to use."

The second uncle and others pushed a small cart, stacked these PVC-C casings, and then transported them to the second outer city.

At this time, in the Second Outer City, Zhou Ran and others have already constructed the style of the iron railing and control system according to the size, and the next step is to make it.

In this workshop, there are also some things like circuit boards, which can be used directly, and everyone started to make them directly.

.........

In the inner city, Ding Jiu, Lao Lu and others cleaned up the sediment and garbage in the sewer.

Li Yu sat on the sewer well, stroking the tortoise that Lao Lu brought up from the sewer.

"Old tortoise, why do you think you went there?" Li Yu tapped the tortoise's shell with his middle finger.

The tortoise stretched out its head and looked at Li Yu blankly.

Li Yu withdrew his hand, raised his head, and said slightly with emotion: "Stay well, don't run around, the storm is coming..."

The sun was shining brightly at this time, and there were no signs of heavy rain or flooding.

Because of this, many survivors let down their vigilance, and Li Yu knew that when the disaster came, they would be devastated.

……

Time passed little by little.

After three or four hours.

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

Ordinary pine trees have a diameter of more than 20 centimeters. These pine trees have a diameter of 45 centimeters and have grown for at least 70 years.

Li Yu hugged the big tortoise and carried it to the residential area.

Such an old Chinese tortoise with a diameter of 50 centimeters and a weight of tens of kilograms must have lived for at least several decades.

This thing is good to keep at home.

There is also a fence in the residential area, but the fence in the residential area is not high. Li Yu put the tortoise down at the entrance of the villa and let it choose a place to stay.

"Mr. Li, our side has been cleaned up, and the wiring system and iron railings can be installed at any time." Xu Zhen's voice came from the intercom.

"Okay!" Li Yu immediately picked up the walkie-talkie and replied.

the other side.

Lao Zhou is wearing a welding helmet and welding the iron railings with carbon steel electrodes.

The plugboard for controlling the circuit is fully sealed with waterproof material, and the entire circuit is covered with waterproof and heat-resistant material.

In addition, the circuit wires are externally packed with PVC-C sleeves to protect the wires inside.

At this time, Li Yu's voice came from the walkie-talkie: "Xiaohang, what's the progress over there? Lao Lu and the others have already done it, and they can install it at any time."

Li Hang looked at Lao Qin, and Lao Qin pointed to a pre-made iron railing and casing, "Take this first and install it, and bring the rest later."

Li Hang nodded again and again: "Okay."

Immediately after talking to Li Yu, Li Yu asked Li Hang, He Chao, and Zhou Ran to take these things around the big camphor tree base and come to the cliff.

After a while, Li Hang and the others drove the car and transported these things to the cliff.

Li Yu, Ding Jiu and the others are now beside the boulder, watching them drive slowly over.

In the sewer, Lao Lu, Xu Zhen and others were waiting below.

.........

The sun was slowly setting to the west, and it was already 4 o'clock in the afternoon, and it would go down the mountain in another hour and a half.

In the base of the big camphor tree, the wind blows the rice, exuding a fragrant smell.

In the scientific research room, there was a sound of discussion.

Bai Jie said helplessly to Anya:

"Xiaoya, you need fertilizer.

Just use soil fertilizer directly. I will give you five methods.

First, ammonium bicarbonate fertilizer
Method: 100 catties of fresh cow dung (chicken manure and sheep manure are also acceptable), 1 catty of soybean powder, and 8 catties of calcium sulfate (Plaster of Paris).

Second: ammonium sulfate fertilizer.

Just use 50 catties of human excrement, 5 catties of calcium sulfate [Plaster of Paris], add 20 catties of water, stir and mix evenly, and seal it for 10-15 days. This fertilizer is mainly used for topdressing and ditching with time bytes Follow up.

Even if you are afraid that you need to use compound fertilizer, the method is very simple.

150 jins of human excrement and 100 jins of superphosphate are mixed and stacked, and the top is sealed with soil. Generally, it can be used in 7-10 days. The fertilizer made by this method can be used as base fertilizer and topdressing. It is best not to use it for seed mixing, so as not to affect the germination rate.

 …”

Bai Jie finished speaking in one breath, she couldn't figure it out, An Ya should know this knowledge.

as predicted.

"I know what you said. I asked you for pesticides. I found some bugs in the crops last time. Just in case, you can prepare some basic pesticides for me." Anya said.

"I should have said it earlier..." Bai Jie was stunned for a moment and murmured.
