I am a Primitive Man

　　 But these three walls that add up to no more than 1,100 meters are still a huge project for the Qingque tribe.

　　 Han Cheng simply settled an account.

The adobe made in the 　　 tribe is a large adobe with a thickness of ten centimeters, a width of twenty, and a length of forty.

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

　　 Yesterday, I tried to make a day's soil culture, even digging the soil belt and mud, and transporting the made adobe to the side.

　　 There are twenty-five people in the tribe who participate in labor, almost all of them are the main force in the tribe. In one day, only 800 pieces of adobe have been made.

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

　　 This is not the time to transport the dried out to the required place.

　　 Taking into account the weather such as overcast, rainy, thunder and wind, it takes six or seven months to build and transport the adobe...

　　 And this is still under the circumstance that the people in the tribe don't do anything else and go all out.

　　 If you count fruit picking, burning trees to plant canola, grassing deer and rabbits, etc.

　　 It’s almost ten months after the adobe is just finished and transported in place...

　　 It is necessary to dig some foundations and build up the adobe blocks into walls with mud, which also takes a lot of time and effort.

　　 Calculated this way. After removing the two or three months when he could not work outdoors in winter, Han Cheng discovered that by the autumn of the next year, he didn’t know if the wall he wanted would be able to come out!

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

　　 Han Cheng couldn't help but wanted to yell.

　　 It’s impossible to follow this method, it takes too much effort!

　　 For several days, Han Chengdu was thinking about this thing that made him frown.

　　 really gave him some eyebrows. This method is to use plate construction instead of adobe to build the wall.

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

　　 This is also the main reason why in ancient times, when one party drew water to fill the city, some parts of the city wall would collapse after a few days.

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

　　 It only needs to use boards to prop up the two sides and two ends of the wall where the wall is to be built, and then put the muddy mud directly into the space enclosed by the boards, and then make the mud firm.

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

　　 After Han Cheng remembered the printing technique, he shot his forehead straight, his thinking was restricted again.

　　 In later generations, steel bars, cement, bricks and tiles are the most common for building walls. Nowadays, white ash is rarely used.

The 　　 plate-building method is basically rarely seen, that is, there is, it also uses a very small layer when laying foundations or ‘ring beams’.

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

　　 If there is no brick, use adobe instead, if there is no cement, use live mud instead.

　　 It wasn't until he realized that this was too labor-intensive and time-consuming and not too strong, and after thinking and meditation, did he suddenly think of plate-building, this ancient wall-building technique.

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

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

　　 It wasn't until he read Mencius's "Born in Worry, Died in Ease", that his mind felt like being struck by lightning.

　　 The original text is like this-Shun was issued in the acres, Fu Shuo was held in the printing plates, the glue was held in the fish and salt, Guan Yiwu was held in the sea, Sun Shuao was held in the sea, and Baili was held in the city.

　　 Therefore, the heavens will descend on the great responsibility and the human beings, and they must first suffer their minds, work their muscles and bones, starve their skins, and empty their bodies...

　　 This chicken soup, what benefited Han Cheng a lot was not because the heavens descended from the great responsibility and the people, but the beginning sentence, ‘Shun was sent out in the acres, and Fu said it was held between the printing plates. ’

　　 It’s okay, I still have to read more and give myself two bites of chicken soup. Doesn’t this come with surprises?

　　 The first time he remembered the printing technique, Han Chengcheng stopped the big brothers and the others from making adobe.

　　 However, there are some difficulties to overcome when using plate construction to build a wall. The most important thing is the foundation of the wall.

　　 If you don't lay the foundation, you can directly build the plate on the ground, it will definitely be weak.

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

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

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

　　 In the west of the tribe, there are already more than 300 square meters of trees that have withered, UU Reading www.uukanshu.com These are the masterpieces of Han Cheng and theirs.

　　 But if this is really done, the construction of the wall will need to be delayed, because it will take a long time to scrape the trees and wait for them to die and wither.

　　 This is a bit unbearable for Han Cheng, who is eager to build the wall.

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

　　 Han Cheng led a large-scale maneuver on this forest.

　　 The first unlucky ones are the trees that just grow on the line drawn by Han Cheng to build the fence.

　　 The weather in early summer was extremely hot, especially now. Without a bit of wind, the whole world is like a steamer. It is so suffocating.

After peeling off the last bit of bark from the roots of a big tree that could not be hugged, even the strongest big brother had to stop, wipe off the sweat from his head, pick up the water bottle at hand, and irrigate his neck. After going down, it was slightly salty and cool and white, and then he exhaled a long breath, and felt relaxed.

　　 Big Brother is actually quite curious, because if it were in the past, in this kind of weather, they would not have much strength, but now it is different. After enduring this hot work, he still feels stronger than before.

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

　　 Looking at the **** son who is still looking at the sky as a child not far away, the big brother's eyes are full of respect. It is precisely because of the **** son's guidance that the people of their Qingque tribe can live such a good life now.

　　 At this time, seeing the **** son look at the sky seriously, everyone including him subconsciously held their breath for fear that it would disturb the communication between the **** son and the god.
