Chapter 51

But even these three walls, which add up to only 1,100 meters, are still a huge project for the Qingque tribe.

Han Cheng simply calculated an account.

The adobe made in the tribe is a large adobe ten centimeters thick, twenty wide and forty long.

Assuming that the wall is built to be two and a half meters high and 40 centimeters thick, it will also require 137,500 pieces of adobe.

Yesterday, I tried to build soil for a day, including digging belts and mud, and moving the finished adobe to the side.

Twenty-five people in the tribe participated in the labor, almost all of them were the main force in the tribe, and they only made 800 pieces of adobe in one day.

Even if you are proficient in all the technologies in the future, based on 1,000 pieces of adobe per day, it will take more than four months, almost five months, just to build the adobe.

This is not counting the time to transport the dried to the desired location.

Considering the cloudy, rainy, thundering and windy weather, it will take six to seven months just to build and transport the adobe...

And this is when the people in the tribe don't do other things and go all out.

If you count things like picking fruit, burning trees to grow rapeseed, making grass for deer and rabbits and so on.

It will take almost ten months to get the adobe ready and move it in place...

Later, some foundations will need to be dug, and the adobe will be piled up piece by piece with mud to form a wall, which will also take a lot of time and effort.

After doing the calculations like this, after removing the two or three months when he couldn't work outdoors in winter, Han Cheng found that in the autumn of the next year, he didn't know if the fence he wanted could come out!

Damn it, it's really hard to make something!

Han Cheng couldn't help but want to curse.

It is impossible to make it according to this method, it takes too much effort!

For several days, Han Cheng was thinking about this matter that made him frown.

It really gave him some clues, this method is not to use adobe, but to use the block method to build the wall.

Until the Qin and Han Dynasties, and even later dynasties, many city walls were built using the plate-building method.

This is also the main reason why some parts of the city wall collapsed after a few days when one side diverted water to irrigate the city during a war in ancient times.

Compared with making adobe first, and then bonding the adobe together with mud to build a wall, the block building method saves much effort and time.

It only needs to use boards to prop up the two sides and the two ends at the place where the wall is to be built, and then put the reconciled mud directly into the space enclosed by the boards, and then beat the mud firmly.

The wall built by this method is one piece. Now that there is no steel bar, cement, lime, and rice, such a wall is much stronger than that built with adobe.

After Han Cheng thought of the version building method, he also slapped his forehead, and his thinking was restricted again.

In later generations, steel bars, cement, and bricks and tiles were the most commonly used for building walls, and now even lime is rarely used.

The plate-building method is basically seldom seen, and even if there is, it is also used when laying foundations or 'circle beams', with very few layers.

So when Han Cheng was about to start building the wall, the first way that came to his mind was to have bricks to build.

If there is no brick, it will be replaced by adobe, and if there is no cement, it will be replaced by living mud.

It wasn't until he realized that this was too labor-intensive and time-consuming and not very strong, and after thinking hard, he suddenly thought of the plate-building method, this ancient craft of wall-building.

And the most direct reason that reminded Han Cheng of this skill was that Han Cheng encouraged himself.

The difficulty of building the wall made him a little discouraged. In order not to lose his confidence, he began to pour chicken soup for his soul.

Until he chanted Mencius' "Born in sorrow,

After Die in Peace, my mind became enlightened as if struck by lightning.

The original text is like this-Shunfa was raised among the farms, Fu Shuo was raised among the boards, Jiaoge was raised among the fish and salt, Guan Yiwu was raised among the scholars, Sun Shuao was raised in the sea, and Baili Xi was raised in the city.

Therefore, when heaven will send a great mission to human beings, they must first suffer from their will, exhaust their muscles and bones, starve their skin and skin, and empty their bodies...

What benefited Han Cheng a lot from this piece of chicken soup was not the fact that God sent a great responsibility to people later on, but the sentence at the beginning, "Shun was born in the farm, and Fu Shuo was held in the boards and buildings." '

Sure enough, I still need to read more books and pour myself two mouthfuls of chicken soup. Wouldn't it be a surprise if I didn't drink it?

The first time he thought of the method of building bricks, Han Chengcheng stopped the big brother and the others from making adobe.

However, there are still some difficulties to be overcome in the construction of the wall with the plate-building method. The most important thing is the foundation of the wall.

If you don't lay the foundation and build the plate directly on the ground, it will inevitably be unstable.

But it is also not easy to lay the foundation according to the current tools and methods.

In addition to these, there is another problem of clearing the forests that grow in this area.

The easiest way, of course, is to kill the tree first, and then burn it with a fire.

In the west of the tribe, more than 300 square meters of trees have died. These are the masterpieces of Han Cheng and the others.

However, if this is really done, the construction of the fence will need to be postponed, because it will take a long time to scrape these trees and wait for them to die and dry up.

This was unbearable for Han Cheng who was in a hurry to build the wall.

But there is no way. With the current production conditions, we can only be the first to endure.

Han Cheng led the people to attack the forest on a large scale.

The first unlucky ones were those trees that happened to grow on the line that Han Cheng had drawn to build the fence.

The weather in early summer is extremely hot, especially now, without a little wind, the whole world is like a steamer, making people breathless.

After peeling off the last bit of bark from the root of a big tree that couldn't be hugged, even the strongest senior brother had to stop, wipe the sweat off his brow, pick up the water bottle at hand, and pour water on his neck. After going down, the breath was slightly salty and cool, and then I let out a long breath, feeling a little more relaxed.

The elder brother is actually quite curious, because in the past, in this kind of weather, they would not have much strength, but now it is different, enduring the heat and working, he still feels stronger than before.

He attributed this to the fact that after the arrival of the Son of God, he brought them plenty of food, so that everyone could eat enough every day.

Seeing Shenzi who was still a child looking up at the sky not far away, the elder brother's eyes were full of respect. It was because of the guidance of Shenzi that the people of their Qingque tribe could live the good life they are now.

At this time, seeing Shenzi looking at the sky seriously, everyone including him subconsciously held their breath, for fear of disturbing the communication between Shenzi and the god.
