Honghuang, I am engaged in science and technology in the Wuzu

“It’s so pretty!”

“We will all live in houses like this!”

“I heard Brother Hao say that such a house can shelter from the wind and rain, and it will no longer be frozen in winter, Brother Hao is really powerful!”

“Such a strong house, even a fierce beast has nothing to do!”

With the curious voices of everyone, the house was covered with the last tile, and at the same time announced the completion of the first building of the Redstone tribe.

Unlike the humble huts, which can only shelter from the wind and rain, this is the first formal man-made structure in the flood wilderness, and it truly has the ability to protect humans.

Especially the hardwoods that are as strong as steel make the house exceptionally strong.

This building, which Fang Hao called the tribal hall, was specially designed by Fang Hao to resist the cold above minus 30 degrees.

The whole hall is 30 meters in circumference, three meters high, circular, in the center of the village, which will be the most important building of the tribe.

Next to the hall is an ancient tree, the only tree left in the village, this large tree is three hundred meters high, five meters in diameter, with lush branches and leaves, and bears a lot of fruit on it.

The reason why the Redstone tribe was able to survive and persist for hundreds of years was that the fruit of this big tree was a great contribution.

This is a fruit like an apple, each fruit is the size of a watermelon, and this fruit has a miraculous effect on saving lives, if you are injured and eat a fruit, it will be good for a few days.

In fact, this can be regarded as a kind of spirit fruit, I don’t know how many injured tribal members have been saved, so it is regarded as a sacred tree by everyone in the tribe.

The wall of the tribal hall is composed of solid wood columns, each column is about one meter in diameter, up to three meters, buried three meters underground, very strong, the wooden wall has a total of two layers, if in winter, Fang Hao will put thatch in the middle of the wooden wall, so that it constitutes a thick wall, both windproof and warm.

This is a temporary construction method, Fang Hao plans to fire steel in the future, it will be more durable and warmer, but this kind of house is not suitable for summer use, it is too hot inside.

The main beam of the tribal hall is a stone pier, a stone pillar made of granite, buried deep in the ground, and the reason why Fang Hao chose to build the hall here is because he values it and can solve the trouble of the main beam.

There is a distance between the stumps and the stone pillars of the wall, which are built from ten-meter-long columns and then tightly tied to the stakes, and there are currently no woodworking tools, so there is no way to put them together more firmly, only rope.

It is inevitable that the rope will slowly age over time and then rot.

The tiles of the hall are thick bark, which play the role of tiles.

This forest is full of big trees, some trees have lived for hundreds of thousands of years, the bark is very strong, Fang Hao chose a strong bark.

This is up to ten centimeters thick, and the bark is firmly tied to the beams, which can play a role in sheltering from wind and rain, and the tile structure can be used for gout.

If it snows, Fang Hao is also ready to cover the roof with thatch, so that it is more insulating.

The reason why Fang Hao built the house like this is because it refers to the architectural design of the north.

On Earth, buildings in the north and buildings in the south are different, and the biggest difference is the thickness of the walls.

The walls in the north are generally strong and heavy, while the building walls in the south are thin.

So in winter, the south has a colder feeling than the north, and in the summer there is a feeling that the north is hotter than the south.

Because the building in the south is easy to dissipate heat and has no heat preservation function, while the building in the north is very thermal insulation and has no heat dissipation function.

Of course, entering the 21st century will not feel obvious, if the installation of air conditioning everywhere is warm in winter and cool in summer, this is the research results of many scientists in modern civilization, reflecting the greatness of civilization.

“Let’s continue to build the torch, everyone carefully remembers, in the future, you can also build the torch independently.” Fang Hao said, and began to teach everyone how to repair the torch.

Built in the center of the hall, with a radius of ten meters, this is a large torch used for people to gather for heating.

Because of the closed environment, it is also necessary to build ventilation ducts, which can also be heated by the ondol, which can avoid extreme cold, Fang Hao set the minimum temperature to minus 60 degrees.

The smoke window adopts the rural smoke window structure, which can effectively ventilate and avoid fire in the hall.

Because the torch is relatively complex and requires high air tightness, everyone spent two days to build.

“Burn fire!”

With Fang Hao’s order, the flames began to burn, but to Fang Hao’s surprise, as the fire in the kang started, thick smoke began to fill the entire hall, choking everyone to tears and flee this terrible room.

“Fang Hao, what’s going on?” Outside the house, Feng asked in surprise, she thought that this time she would definitely enjoy the warmth of the torch?

Now the temperature is getting worse and it is starting to get colder.

“It’s okay, don’t worry, the reason why there is thick smoke is because of the design flaws, but we can burn charcoal to solve it.” Fang Hao’s mind turned and he thought of a way.

“But where is so much carbon to burn?” Susu, a woman in the tribe, asked about the carbon, which she knew, the black object left behind after the fire, which can burn.

“It’s not hard to get a lot of carbon, we can burn charcoal.” Fang Hao said.

Born in a mountain village, he saw charcoal burned as a child, and as a child, carbon was a must-have for heating in winter.

“How do you burn carbon?” Feng asked.

“It’s very simple, you can burn charcoal directly using the brick cellar.” Fang Hao said, and began to explain the principle of charcoal burning to everyone.

Charcoal-fired wood is the most critical, and the carbon fired will be burnable, odorless and warm.

First of all, dig an arc-shaped cave with an upper radius of one meter and a middle radius of 1.5 meters, and dig a horizontal exit at the bottom of the cave, 0.4 meters wide and one meter high.

The second step is to strengthen the carbon cave, use a large fire to burn the cave, and burn the fire in it for 30 minutes every day, the longer the better, until the cave solidifies, so that you can start burning charcoal.

The third step is to put in the wood, put the selected wood into a cave to burn according to a wooden strip about one meter long, and wait until there is a certain amount of bottom ash.

After the temperature of the cave rises and the redness, all the wood is put into the cave, and there should be a gap between the wood.

Wait until the surface of the cave wood is on fire, you can seal the upper wellhead, and then seal the lower transverse wellhead, of course, to maintain a tiny gap so that the cave continues to maintain high temperature.

At this time, the cave will always be smoking, and after waiting for more than ten days, the cave will gradually turn into green smoke, and finally no longer smoke, at this time, the cave can be completely sealed, so that the fire in the cave is completely extinguished.

After the cave cools, the high-quality charcoal comes out.

Of course, charcoal burning is not so simple, there are many technical requirements, those who are experienced to burn carbon is more useful, charcoal burning technology brings together thousands of years of technology crystallization.

For example, carbon is divided into many types, such as carbon for heating and carbon for steelmaking are different, and the carbon technology requirements for steelmaking are very high.

Fang Hao only understands a little about charcoal, and using carbon to make steel is Fang Hao’s next plan, and the charcoal burning technology still needs to be improved by the tribesmen.

As a result, the Redstone tribe began a vigorous charcoal burning campaign again, and the entire tribe became a huge construction site, the cottage range continued to expand, and the wall was constantly updated.
