Two o'clock in the afternoon.
Li Yu walked on the wall, watching people coming out of the room one after another, pouring under the scorching sun.
The residential building originally planned by Ding Jiu and the others is almost completed.
There are two floors underground and four floors above ground.
The foundation was dug to 8 meters. This depth of foundation is enough to build more than 20 floors without any problems.
The foundation is large and solid, so even if there is vibration, it will hardly affect the building.
Li Yu was quite satisfied when he saw this residential building that was about to be built.
But when he moved his sight to the place where the bunker was originally built, he found that the progress of the bunker construction was extremely slow.
So far, the entire bunker has been excavated in less than 2 acres and the depth is less than 6 meters.
This is far different from the 5 acres and 12 meters depth they originally planned.
After searching around, Li Yu found Ding Jiu.
Ding Jiu was currently communicating with Xiao Qian, who majored in civil engineering.
Li Yu walked over. When Ding Jiu and Xiao Qian saw Li Yu coming, they stopped communicating and focused on Li Yu.
Li Yu frowned and looked at the two of them and said, "Why was the construction of the bunker at this progress when I left, and why is it still like this now?"
Ding Jiu saw Li Yu frowning and said quickly: "Mr. Li is like this. Our main focus now is on building this residential building. Originally, we also wanted to build the bunker first.
However, we found that such level excavation work is very heavy, and the construction of the drainage system will be very complicated. We have talked about this matter with drainage engineer Xu Zhen in the past two days.
If we still follow the original plan, it is estimated that with our current manpower, it will take at least three months to complete it.
The width is not a big problem, the main thing is the depth, 12 meters is a very large workload, and the depth of 12 meters is basically in the groundwater."
The underground water in Jiangnan is shallow. They have dug to a depth of 6 meters and water has come out.
When Li Yu heard this, his brows were still furrowed. He knew it was very difficult.
But this matter is very important. There is no way he can tell them that in more than a month, the volcano will erupt, and the world will become dark by then, with volcanic ash floating everywhere in the atmosphere.
Seeing that Li Yu was still frowning, Ding Jiu said: "Mr. Li, your father, I, and your second uncle also discussed this matter.
In the past two days, I have come up with a better idea, which is to build this bunker to its current depth and width for the time being, and then excavate it in the two mountains in the inner city.
If you choose to excavate on a hillside, you can dig up or down, and the amount of work will be reduced a lot.
Not only will the demand for raw materials be greatly reduced, but the stability will also be very high.
At our current rate of cement production, there is still some shortcomings in building residential buildings.
So we will build the residential buildings first, and then decide whether to use this plan after you come back."
When Li Yu heard this, he immediately understood.
The main reason why we do not continue to dig in the Second Outer City is because as the depth increases, the workload will increase geometrically.
Moreover, the amount of cement, reinforced concrete and concrete consumed is also an astronomical figure.
Just building this residential building has consumed a huge amount of sand and gravel.
Li Yu was on the wall, looking towards the two mountains in the city inside the base.
On those two mountains, a watchtower and a large solar panel were built on the top of the mountain.
There are also some wind turbines and the fan blades of wind power are still rotating slowly.
Seeing Li Yu looking at the two mountains, he seemed a little moved. Ding Jiu rummaged through the drawings in his hand, found one, and handed it to Li Yu.
"Nuo, Mr. Li, look, this is our planned drawing. These two mountains and forests cover more than 200 acres. Our idea is to build the mountain on the east side.
Excavate on the hillside in the direction of the sun.
Excavating a bunker with a height of 6 meters and an area of about 10 acres can be completed in more than two months.
How do you feel?"
"More than two months?" Li Yu originally watched with interest, but after hearing this time, he suddenly felt dissatisfied.
More than two months later, by that time, the volcano would have already erupted.
Now we just need to get these done as quickly as possible.
So he said, "Can it be done in a month? It's relatively hot during the day, so we can work two shifts and dig at night. Do you think it's feasible?"
Ding Jiu and Xiao Qian looked at each other and said hesitantly: "We can indeed speed up the progress at night. Now the residential building can be built tomorrow. It will be much faster if half of the manpower is used to dig the cave.
However, if we dig at night, will the sound be too loud and attract zombies?"
Li Yu thought for a while and realized that this was a problem, so he said, "If we mainly carry out low-noise operations at night, we can use heavy machinery during the day. Is this feasible?"
Ding Jiu thought about it and finally said: "Should, yes."
Li Yu said: "Okay, then follow this method. Complete the residential building as soon as possible. The decoration does not need to be complicated, just use cement walls.
But one thing you need to pay attention to is that the ventilation system and thermal insulation must be done well.”
Ding Jiu expressed his understanding.
Li Yu then asked him to continue working.
Seeing everyone in the base sweating profusely, Li Yu had no time to stop and rest.
A lot of things inside and out.
He found He Chao again and asked him to go out to collect building materials tomorrow, and at the same time contact the personnel stationed outside and non-staff personnel to ask them to pay attention to whether there were any strangers around them.
Once discovered, follow it immediately and report it to the Da Zhangshu Base.
In addition, He Chao also reported a problem, that is, it has become increasingly difficult to find and collect raw materials recently.
I traveled far today and found a steel plant in the northeast, but this steel plant is completely enclosed.
After they entered, they found that there were zombies inside.
These zombies are probably employees in the factory. Since the outbreak of the apocalypse, these zombies have not gone out, and no one has come in.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! After Li Yu heard the news, memories came to mind. There are indeed no large steel plants around Xincheng, but there are many rare earth mines and
Tungsten.
But in the northeast, there is a small city and an iron mine. It is not far from Xincheng, about a hundred kilometers away.
The base is currently under construction, residential buildings need to be built, and the newly dug bunker needs to be poured and capped, and finally filled.
Next, we have to carry out excavation work in the mountain.
And we can't spread our manpower too far apart, because there may be people coming from Chengzizhoutou.
He saw Xiao Jun's vehicles in Wengcheng.
A flash of lightning flashed in my mind.
He suddenly had an idea, Xiao Jun and the others could be allowed to do this. They had enough experience and strong combat effectiveness, so they could definitely be allowed to go.
It just so happens that it can be regarded as a test for them.
It's just that you need to use a suitable wording to talk to them about this matter.
After thinking about all this, Li Yu said to He Chao: "I understand. Tomorrow, tomorrow at the latest, I will give you an answer. Then I will give you manpower to deal with the zombies over there."
When He Chao saw Li Yu's answer, he suddenly felt confident.
The recent building materials incident has troubled him.
Cement, sand, steel bars, lime, floor slabs, stones, bricks, glass, metal, tiles, wooden boards, linoleum, waterproof coatings, doors and windows, iron wire, casing, PVC pipes, nails, sealant, glass....
.....
There are some things that are not available and they need to make them themselves, such as cement. They get the limestone themselves and then cement it at a high level.
Because the demand is too high, they have now built several small factories in the Second Outer City.
After Li Yu and He Chao finished chatting, they returned to the First Outer City.
A residential building in the Second Outer City, under the eaves.
Li Yu saw his third uncle and Xiao Jun chatting from a distance.
They seemed to be having a great time talking.
Li Yu walked over and said to his third uncle: "Third uncle, where is that little orange cat that has been following you?"
The third uncle turned around and saw Li Yu, and said with a smile: "Xiao Yuan took it for examination, saying it was to check whether there were parasites or anything like that."
Li Yu nodded and said to his third uncle, "I'll have a chat with Captain Xiao."
"Okay, you guys can chat," said the third uncle.
As he stood up and wanted to leave, Li Yu said, "Uncle Third, please listen together."
The third uncle sat on the stool again, said a few good words, and then drank the water by himself.
Xiao Jun's eyes were bright. He wanted to know what Li Yu wanted to see him for.
Li Yu smiled and said to Xiao Jun: "Don't be so nervous, I just have something to ask you."
Hearing this, Xiao Jun said politely: "Mr. Li, your words are embarrassing me. There are so many people in Da Zhangshu Base, why do you still need my help?"
Li Yu said seriously: "With more people, there are more things to do. Now the base needs someone to plant and protect it. New buildings are also being built recently, so it is very busy recently.
Our base adopts a points system, which you should be aware of."
"Uncle Li and Captain Lu have both told me." Xiao Jun said.
"Uncle Li?" Li Yu looked at Uncle Li suspiciously.
"Is the Uncle Li you are talking about my third uncle?" Li Yu asked.
The third uncle coughed and briefly told Li Yu about his relationship with Xu Chengcai, who was Xiao Jun's uncle.
Only then did Li Yu understand.
He smiled and said: "It turns out that we are all our own people. Hahaha, if you are our own people, I won't be polite."
Then he said to Xiao Jun seriously: "You also know that the weather is changing a lot now. Look at the current temperature, it should be 47 degrees."
Xiao Jun wiped his sweat and said with a wry smile: "Yes, this weather is indeed a bit difficult. But, what does this weather have to do with what I am asked to do?"
Li Yu said: “Last year’s high temperatures, extremely cold weather with ice and snow, and the subsequent locust plague have made planting very complicated.
This year's temperature is also extremely abnormal.
Therefore, I want to build some underground planting areas, or some bunkers, for indoor planting, so that food production will be more stable.
But now, building materials have encountered some problems.
I can't spare any manpower here at the moment, so I'll see if you're willing to solve the problem of building materials."
When Xiao Jun heard this, not only was he not dissatisfied, but he said happily:
"Of course I am willing. If there is something we can do, we should be willing. After all, you can still redeem points and food here, right. We still owe 100 kilograms of food. Haha."
Li Yu waved his hand and pressed it, saying:
"I haven't finished yet. Here's the thing. My people found a steel factory in the northeast. There are a lot of zombies inside, so we need some people to help lure the zombies away. Then my people can go inside and collect the steel.
, and some instruments and equipment were moved out.
There will be certain risks, take a look and see if you are willing to do it?"
When Xiao Jun heard that there were still many zombies inside, he was silent for a moment and said to Li Yu: "Okay, but I'm not very familiar with it there. I need someone to take us there."
Li Yu immediately said:
"That's for sure. I will send people to go there with you. The old Lu from our base whom I introduced to you last time will go with you, and He Chao and a few others. They are familiar with that place.
You can go together when the time comes.”
Xiao Jun nodded and said, "Okay, then there will be no problem."
Li Yu stretched out his hand and said, "It's a pleasure to cooperate."
“A pleasure to work with.”
.........
Xiao Jun and the others stayed in the first outer city of the base for three hours.
Later, I asked my third uncle to give them some basic daily necessities, some pots and pans, and 100 kilograms of rice.
He took them to the house on the side of the rural road 200 meters away from the base.
They lived in the same house where Lao Qin and the others first came to live.
The yard is still the same as before. It was tidied up by Lao Qin and others, although there is a lot of dust floating in it these days.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! But there is basically no garbage.
There is a well and a walled courtyard, which can accommodate Xiao Jun and more than thirty people.
.......
After explaining all this, it was evening.
Li Yu dragged his exhausted body back to the basement of the villa.
Basement second floor.
B2
The innermost room was locked.
Take out the key and open it.
Entering this room, there is a futon, a desk, and a pot of green plants.
There is also a painting hanging on the wall, A Thousand Miles of Rivers and Mountains.
Li Yu walked to the wall and looked at the painting.
Turn around and close the door.
Then he walked to the pot of green plant, lifted the green plant, and pressed it against a piece of floor under the green plant.
Kakaka——
The wall suddenly slowly slid to the left and right,
A downward step is exposed in the middle.
Li Yu took a flashlight and walked down.
After walking down about four or five meters, we entered an empty basement.
Li Yu touched the wall skillfully, and instantly the light in the middle of the basement came on.
Suddenly, the walls of the basement were filled with names of numerous people, as well as some time nodes. Except for him, no one else could understand the meaning of the symbols.
Some of them are such as:
August.△.
September.?!
...
At the end, where there were many names, Li Yu wrote a name: Xiao Jun.
Then he wrote a few more names.
Gan Shang: x
Ganxiong:x
Behind Xiao Jun, Li Yu hesitated for a few seconds before hitting a?
.....
On the far right side of the basement, there is a small steel door.
It was tightly closed and covered with dust.
Li Yu looked at it with thoughtful eyes.
