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

Han Cheng simply calculated an account.

The adobe made in the tribe was 10 centimeters thick, 20 centimeters wide, and 40 long.

Suppose that the wall is built two and a half meters high and 40 centimeters thick, it would also require 137,500 adobes.

Yesterday, I tried to build soil for a day, digging with soil and mud, and carrying the made adobe aside.

Twenty-five men of the tribe participated in the labor, which was almost all the main force of the tribe, and at the end of the day only eight hundred adobes were made.

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

That's not counting the time it takes to get the dried ones to where they need to be.

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

And this is when the people in the tribe do not do anything else and go all out.

If you add to that the fruit picking, burning the trees to grow rape, and getting grass for the deer and rabbits, and so on.

It was almost ten months before the adobe was ready and moved into place......

Later, it was necessary to dig some foundations and mud to build up the adobe piece by piece to make a wall, which also took a lot of time and effort.

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

it, it's so hard to make something!

Han Cheng couldn't help but want to scold.

It can't be done according to this method, the effort is too great!

For a few days, Han Cheng was thinking about this thing that made him frown.

It really gave him some eyebrows, and this method was to use the plate construction method to build the wall instead of adobe.

Until the Qin and Han dynasties, and even later dynasties, many of the city walls were built using the plate construction method.

This is also the main reason why in ancient wars, one side diverted water to irrigate the city, and after a few days, some parts of the city wall would collapse.

Compared with making adobe and then gluing it together with mud to build a wall, the pattern construction method is much less labor-intensive and time-saving.

It only needs to use boards to support both sides and two ends of the fence at the place where the fence is to be built, and then make the mud directly into the space enclosed by the board, and then make the mud strong.

The walls built in this way are one, and in the absence of steel bars, cement, white ash, and rice in the present, such walls are much stronger than those built with adobe.

After Han Cheng remembered the version construction method, he also slapped his brain, and his thinking was restricted again.

In later generations, the most common types of walls were steel, cement, and bricks, and now even white ash is rarely used.

The plate construction method is basically rarely seen, and even if there is, it is also used when laying the foundation or playing the 'circle beam', and a very small layer is used.

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

If there is no brick, it is replaced with adobe, and if there is no cement, it is replaced with living mud.

It wasn't until he realized that it was too labor-intensive, time-consuming, and not very solid, and after meditating hard, that he suddenly remembered the method of plate building, the ancient craft of building walls.

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

The difficulty of building the wall discouraged him, and in order not to lose his confidence, he began to pour chicken soup for his soul.

It wasn't until he recited Mencius's "Born in Sorrow, Died in Peace" that his brain became enlightened as if it had been struck by lightning.

The original text is like this - Shun is in the acres, Fu Shuo is lifted between the plates, the glue is lifted in the fish salt, Guan Yiwu is raised in the Shi, Sun Shu Ao is raised in the sea, and Baili Xi is held in the city.

Therefore, the heavens will descend on people, and they must first suffer their minds, strain their muscles and bones, starve their bodies and skins, and empty their bodies......

This chicken soup, what benefited Han Cheng was not the fact that the heavens descended from the sky later, but the sentence at the beginning, 'Shun is sent in the acres, and Fu Shuo is raised between the plates.' ’

Sure enough, if it's okay, you still have to read more books and pour yourself two more mouthfuls of chicken soup.

As soon as he remembered the method of plate building, Han Chengcheng stopped the senior brother's action of making adobe.

However, there are some difficulties to overcome in the construction of the fence by the plate construction method, the most important of which is the foundation of the wall.

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

But laying the foundation is also not easy according to the current tools and means.

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

The simplest, of course, is to kill the tree first, and then burn it down.

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

But if this were to happen, the construction of the wall would have to be postponed, because it would take a long time to scrape the bark of the trees and wait for them to die and dry up.

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

But there is no way, and with the current production conditions, it can only be the first to endure.

Han Cheng led the people to make a large-scale move on this forest.

The first to be unlucky were the trees that happened to grow on the line that Han Cheng had drawn out to build the wall.

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

After removing the last bit of bark from the root of a big tree that could not be hugged by one, even the strongest elder brother had to stop, wipe the sweat from his head, pick up the kettle at hand, and pour it down with his neck up, and then let out a long breath and feel more relaxed.

The senior brother is actually quite curious, because if it was placed in the past, in such weather, they would not have much strength in them, but now it is different, enduring this hot work, he still feels that he has more strength than before.

He attributed this to the fact that the Son of God had brought them abundant food to feed them every day.

Looking at the Divine Son who was still looking at the sky not far away, the eyes of the senior brother were full of respect, it was precisely because of the guidance of the Divine Son that the people of their Qingque tribe could live such a good life now.

At this time, seeing that Miko was looking at the sky seriously, everyone, including him, subconsciously held their breath and condensed, for fear of disturbing the communication between Miko and the gods.
