I am a primitive

But what is different from the past is that the fish caught are not directly transported back to the cave, but are cleaned up on the spot by the small river, and then salt is rubbed on them. The place where the pottery came down to dry.

This is to make dried salted fish.

Those in charge of doing this are some minors in the tribe who can do light work, women with weaker physiques, and of course, lame.

Han Cheng didn't let them throw fish's viscera and fish scales at random, but dug some pits 20 meters away from the river bank and close to the downstream, and threw the viscera cleaned out every day in these pits. When it was time to call it a day in the evening, some dead grass was thrown on top of these internal organs, and then evenly covered with a layer of soil.

Go on in this order, after leveling a pit, change to another pit.

Of course, Han Cheng didn't do any more useless work.

In doing so, the environment can be protected, and fish viscera will not be filled everywhere by the river, and secondly, it can be fertilized.

In autumn, he was going to plant a crop of rapeseed. Now that he had the opportunity, he naturally had to make some preparations in advance.

The construction of the fence is a huge project for today's tribe. Han Cheng roughly calculated the amount of work. Even in autumn, it cannot be completely built.

And autumn is the season for food storage. In order to avoid the problem of food storage from greatly affecting the construction of the wall, Han Cheng took advantage of the hot weather to dry some fish in the sun.

The place specially used to store food in the tribe was circled by thirteen large tanks. In the circled space, under the guidance of Han Cheng, a layer of mud embryos that had been made first and dried in the shade was spread. The mud embryo was covered with a layer of broken animal skins, and on top of the animal skins was a thick layer of hay.

This is the place where the sun-dried fish is placed.

With these three layers of protection, it will not be so easy for the tide to rise up from the ground to play with the dried fish!

As for the empty tanks around them, they are also used to store food.

The bottom of these cylinders is also cushioned with adobe.

Storing food in this way can not only play a good moisture-proof effect, but also save a lot of space.

After he didn't have to worry about food every day, the wall planned by Han Cheng was also put on the agenda.

Han Cheng didn't want to make the wall smaller, because after building the wall, he wanted to build a house inside the wall, build some pens for raising livestock, and at the same time leave enough places for the people in the tribe to rest and play.

It is precisely because the wall is not easy to build that Han Cheng wants to build it well. Otherwise, he has spent a lot of energy now, but he will not be able to keep up with the situation in a few years. If he pushes it to re-expand, it will be a big loss up!

He has been wandering outside the tribe for the past two days. Under the premise of taking care of the terrain, he can basically build a wall that is 300 meters wide from north to south and 500 meters long from east to west.

Because the northernmost side of the wall is the mountain wall where the tribal cave is located, the mountain wall on this side is high enough, so there is no need to build a wall.

In other words, only two walls of 300 meters and one wall of 500 meters need to be built to enclose a sufficient safe space for the tribe!

Chapter 51

But these three walls, which add up to only 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 13 centimeters thick, it will also require 500 yuan of adobe.

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

There are 25 people in the tribe participating in labor, which are almost all the main force in the tribe, and they only made 800 yuan of adobe in one day.

Even if you are proficient in various technologies in the future, based on the 1000 yuan 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, growing 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 a lot of 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 rarely 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 remembered the plate-building method, an 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.

It wasn't until he chanted Mencius's "Born in Worry, Die in Peace" that his 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 later part of the story, but the sentence at the beginning, "Shun was born in the farm, and Fu Shuo was held between 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?
