Dazhangshu base, buffer city.

swish swish——

The mortar in the mixer rolls back and forth, and the sand, gravel and cement are often fully mixed in the mixer, and then poured toward the placed formwork through the delivery pipe.

The formwork is filled with tied steel bars horizontally and vertically, and the viscous concrete is poured on the steel bars to fill the gaps.

Some collaborators use a mixer to vibrate the concrete to ensure that the concrete can fill all the gaps in the formwork.

Crunch!

After Le Ziqing and others entered the buffer city of Dazhangshu Base, they stopped in the right area.

In the current buffer city, all kinds of building materials are piled up like hills.

Crash--

They dumped the sand from the truck on the ground, and one truck after another drove in and dumped the sand out of the truck.

Every building material here is sorted and piled in different locations.

But even so, the construction site still looked a bit messy due to the vehicles laden with materials driving back and forth, causing some sand and gravel to shake out.

Less than a hundred meters away from here, there is a cement factory that was built not long ago.

In the cement factory warehouse, there are piles of cement more than ten meters high, layer upon layer, which looks very spectacular.

These cements have just been produced and need to be stored for a period of time.

The newly produced cement is hot and cannot be put into use immediately, otherwise it will affect the growth strength of the cement.

The temperature of freshly bagged cement will be relatively high after it is delivered. It will be hot to the touch and cannot be poured into concrete immediately.

Because the properties of various ingredients in hot cement have not been fully stabilized, the stability of the cement is unqualified. Only when the cement fully releases its heat can a stable effect be achieved.

But it cannot be left for too long. If the cement exceeds two months, its strength will decrease.

This point was emphasized by Fusheng in the base especially to the construction workers at the construction site.

After unloading the sand, Le Ziqing looked at the time and it was already four-thirty in the afternoon.

It was too late to make another transportation trip, so he said to Shi Jingsheng behind him:

"Jingsheng, you ask the brothers to drive the electric truck to a charging point to charge, and I'll go find someone."

Hearing this, Shi Jingsheng looked around, leaned over and asked in a low voice:

"Brother Le, are you looking for Lai Dongsheng, the inner-city employee, to give you feedback on Zhang Shunzi?"

"Well, this bastard is affecting our ability to earn points, so we must sue him." Le Ziqing looked gloomy.

"Hey, I'm waiting for your good news."

After receiving Le Ziqing's accurate reply, Shi Jingsheng had already thought of the picture of Zhang Shunzi being defeated.

Le Ziqing glanced at Shi Jingsheng and said angrily:

"Drive away quickly, there are other convoys coming from behind."

.....

Lai Dongsheng has a rather special status in the Da Zhangshu base. Although he is only a middle-aged man with low knowledge and culture, his relationship with Li Yu's family was very good before the end of the world.

After the apocalypse broke out, he stayed in the inner city without a fixed position. He went to help wherever he needed someone.

After the projects in the inner city were basically completed, he couldn't take any time off and took the initiative to apply to help in the buffer city.

He is responsible for vehicle entry and exit registration. Just after passing the weighbridge, Le Ziqing had already said hello to him.

But because there were other teams queuing up from behind at that time.

He was also in the car, anxious to transport the raw materials to the material storage area, so he did not get out of the car to report Zhang Shunzi's incident to Lai Dongsheng.

Back in the buffer city, less than fifty meters from the entrance, a pavilion was set up in this place. There were several tables in the pavilion, and four or five people were sitting there.

Opposite the pavilion, there is a weighbridge. Every transport truck entering the buffer city must pass by and weigh the materials on the truck.

Based on this weight, they calculate contribution points in proportion to the partners who go out to transport materials.

These collaborators will exchange these contribution points for food and other materials.

Le Ziqing walked to the weighing scale. At this time, there was no convoy entering, and Lai Dongsheng and Yu Lei were chatting.

He dusted himself off and walked straight towards the pavilion.

Yu Lei saw Le Ziqing walking under the pavilion and said with a smile:

"Hey! Lao Le, today's transportation mission is over. Your transportation volume was good today. Have you found a new sand quarry?"

Le Ziqing walked to the shaded ground of the pavilion, feeling much cooler without being exposed to the hot sun.

"I still took a risk and went to the Gongjiang River to mine river sand. Although it is convenient to mine, there are always some zombies suddenly running out of the river, making it difficult to work."

Hearing what he said, Yu Lei nodded slightly.

He could understand what Le Ziqing said, as he had done the same thing before.

Generally speaking, sand is collected from rivers, mountains and oceans.

There are many kinds of them, including river sand, mountain sand, sea sand or natural sand, which is a natural mineral resource.

In recent years, due to the extensive use of buildings and foundation projects in the Dazhangshu base, as well as the impact of heavy rains and floods, the mountain sand near the Dazhangshu base has become increasingly difficult to mine.

River sand is relatively easy to mine, but it has a very big disadvantage, that is, zombies like water. When mining river sand, you will always encounter some zombies running out of the water.

It's easy to get caught if you're not careful.

Lai Dongsheng, who was sitting in the center, nodded towards Le Ziqing, "Be careful, mutant zombies are much more likely to appear now than before."

"Well, thank you Brother Lai for reminding me."

"Brother Lai, there's something wrong with one of my electric trucks. Do you have time to take a look at it?"

Le Ziqing saw so many people here, including several non-staff members.

I thought of an excuse and took Lai Dongsheng aside to chat.

This kind of snitching must not be discussed in front of everyone.

If these non-staff personnel heard it, if one of them had a good relationship with Zhang Shunzi and the news reached Zhang Shunzi's ears, Zhang Shunzi would definitely cause trouble for him.

After all, he is a person from outside the city. Although he does not have direct jurisdiction over him, he can still find ways to put some shoes on his feet.

Therefore, it is best to tell Lai Dongsheng secretly about this matter in private.

Lai Dongsheng was surprised when he heard this and said: "If you have a problem, go to the maintenance factory in the outer city. They are professional. I know how to repair trucks. These electric vehicles are not the same as fuel vehicles. I can't fix them."

Lai Dongsheng has done many jobs before, including a period of time as a car mechanic.

But the technology is not particularly good.

Lai Dongsheng's answer was already within Le Ziqing's prediction, and he said quickly:

"You are so humble. I have seen your skills with my own eyes. When we were on the weighbridge the day before yesterday, you were the one who found the problem with the truck and fixed it in twos and twos."

"There is still a queue at the factory for maintenance. I have to go out to transport sand tomorrow. I can't wait that long. If you are tired, please help me take a look. It's not a big problem. It's just that there are always abnormal noises when driving."

"Please help me, there are no cars coming here anyway, not to mention Brother Yu and the others are here."

Lai Dongsheng is very popular in the base, which is related to his down-to-earth and helpful personality.

Hearing what Le Ziqing said, he felt that it was not unreasonable.

It only takes one trip, "Okay, don't blame me if it can't be repaired. If it can't be repaired, go find a repair shop."

"Thank you Brother Lai."

Lai Dongsheng explained to Yu Lei here, looked at the registration data on the form, wrote it down, and followed Le Ziqing.

Don't mess with this data. The points of those who cooperate are based on this data.

Although he has a good temper, he is also quite careful in his work.

It should be noted that he has always been more careful.

Yu Lei is an old man at the Da Zhangshu base. He had a broken leg before, otherwise he would have been promoted to an outer city employee long ago.

Let him watch from here, and there shouldn't be any problems.

After leaving the pavilion, Le Ziqing took Lai Dongsheng towards a ruined wall to the west.

The buffer city is very large, and many areas have not yet had time to be built.

Within the buffer city, there are still some residential buildings built before the end of the world, but some of these residential buildings have collapsed, leaving only ruins.

"Xiao Le, the electric truck charging place is not here. Why did you bring me here?"

They were next to a broken wall, about fifty meters away from the buffer city wall. There was a big tree growing next to the broken wall. Although the weeds on the ground had been cleared a few days ago, they have grown again in the past two days.

Some.

The cicadas are chirping and the air is stuffy, making people easily irritable.

Le Ziqing looked around and found that there was no one there, a miserable look appeared on his face.

"Brother Lai, I have something I need your help with."

"Help, where is your car? If you don't pull the truck out, how can I help you repair it?"

"The truck is not broken, I just want to see you for something else."

"You kid, just kid me, I'm busy..."

With that said, Lai Dongsheng walked back on the road.

No matter how good-tempered he is, he cannot accept others lying to him.

"Brother Lai, wait a minute. I have my own reasons. It was difficult to talk because there were so many people. This matter is of great importance and I think I must tell you." Le Ziqing grabbed Lai Dongsheng and begged.

"oh?"
