Rebirth before the doomsday: I quietly emptied the city of supplies

After the earth kiln is built, fill the larger holes with small mud blocks to prevent the flames from jumping out and wasting firewood!

With each layer of stone stacked up, the clay must keep up without any gaps. Otherwise, when the kiln leaks fire when firing things, the temperature will not reach the target.

The quality of things fired in that way is completely different from what you imagine.

Try to touch the earthen kiln as little as possible during the burning process, after all, the earthen kiln made by hand is not very strong!

After a while, the charcoal needs to be cleared to change the oxygen! The burning time depends on the dryness and size of the clay. After it is hot enough, take out half of the charcoal in the kiln and put the things to be burned into it from the fire inlet.

Chen Yu heaved a long sigh of relief until the earthen kiln was more than one person high. It was not an easy task to build this earthen kiln. Now the earthen kiln is ready. It only needs to be air-dried for a while, and then enough coal or firewood is found to burn the earthen kiln with a big fire. After the fire, the earthen kiln will be even stronger. Then Chen Yu did not stop, but continued to dig a lot of silt from the bottom of the river. He used this silt to make bricks and tiles, although there is no sun now. But the temperature next to the freshwater lake is not low, and the excavated silt can be shaped by natural air drying. The excavated silt is made into cubes, placed on the cleaned sand, and piled up piece by piece. When the water gradually dries up and the square soil blocks gradually harden, they can be put into the earthen kiln for firing. And eating less bricks and tiles is inseparable from coal and other combustion-supporting materials.

Therefore, before starting to make bricks, Chen Yu had to stockpile enough coal and minerals.

When firing bricks and tiles, you cannot just use coal. If you add some other minerals to the fire, the fired items will be harder.

Almost without stopping, Chen Yu kept digging out silt from the bottom of the river, beating it hard, and then using molds to make square bricks, which he turned over to the sand on the side to dry.

Building this new shelter should only require a thousand bricks or so.

Chen Yu kept collecting silt from the river, making it into square bricks and placing them on the ground.

When all the silt in this section of the river has been collected, Chen Yu will move up and down randomly to collect the silt.

Although the shelter was mainly built with bricks, Chen Yu also used small molds to make tiles while making bricks. The process of making tiles is much more difficult than making bricks.

After all, each tile needs a mold to be fixed and dried, otherwise the toy tiles will quickly become straight when placed on the ground, losing the arched effect of the tiles. After a whole afternoon of production, Chen Yu finally made all the bricks and laid them on the ground into a large area.

Because of the influence of the mold, Chen Yu didn't make many tiles.

And due to time constraints, when the screen finished making all the bricks, it was actually getting dark.

A day passed like this, although the earthen kiln was completed and more than a thousand bricks were made using molds.

But Chen Yu still felt that the time was too short. Many of the things he wanted to do were not finished before it was dark.

In fact, there is no need to do anything else next. Apart from burning some more tiles, the rest is just to stockpile coal.

For one or two days, Chen Yu did not do anything else. He ran from the shelter to the freshwater lake and concentrated on studying his tiles. Chen Yu cut a lot of thick bamboos and split each bamboo into two pieces in the middle. Then he cut them into sections of a certain length to make them the right size for tiles. Afterwards, Chen Yu beat the excavated silt to shape it and evenly spread it on the bamboo pieces.

On the third day, Chen Yu used the cart he made last time to go to the coal mine. After a whole day of digging, he dug out two large carts of coal. . Everything is ready, only the east wind is missing. Now Chen Yu has prepared all the materials needed to make bricks and tiles. As long as the right time is right, he can start the furnace and burn all the bricks and tiles at any time. Chen Yu has other plans for making this large earth kiln this time.

After such a long period of use, Chen Yu's machete and axe were severely damaged.

Therefore, Chen Yu planned to use the high temperature of the earth kiln to re-forge the machete and axe in his hand after firing the bricks. This time, he did not plan to make cast iron tools again, although cast iron weapons are very hard. But cast iron is too brittle, and if too much force is used, the blade will easily break.

Now that he had this earthen kiln, Chen Yu could refine the machete and axe again to remove the excess carbon. To turn pig iron into wrought iron, only the modern method of pouring steel was barely feasible.

But now they are on a deserted island, and Chen Yu is restricted by various conditions. It is impossible for him to use the steel pouring method to make weapons for himself. The only method that can be used is the original forging method, which is to keep burning it with fire, and then repeatedly hammer it violently... hammer out all the excess carbon in the pig iron, making it infinitely close to the material of steel, which is considered to be barely casting the pig iron into wrought iron. And the black meteorite iron he found in the sea last time is still in the shelter. The impurities in the iron have been completely removed after the high temperature burning in the atmosphere.

Chen Yu wanted to try it out. If he could melt it, he could melt the meteorite into his weapon. This would greatly improve the hardness and toughness of the weapon.

Chen Yu did not waste the remaining time. After two or three days of air drying, the bricks had just reached the moisture content required for firing. Chen Yu had no time to pay attention. He kept sending bricks into the 3.6 earthen kiln and fired them fiercely using the coal-burning fire. More than a thousand bricks took more than three days to burn, and the coal was completely consumed.

After the bricks are fired, the next step is to make tiles. The production of tiles is relatively difficult, but firing them is much simpler. Because tiles are relatively thin, they can be piled up in large quantities in the earthen kiln for firing.

On this day, Chen Yu was firing tiles outside Tuqiao. Thousands of tiles were almost fired, and only one furnace was left to complete the work. . "Hiss, hiss, hiss! What bad luck! I bumped into a god today! Chen Yu, run!"

Just when Chen Yu was about to burn the last batch of tiles, She Er, who was wandering around, suddenly ran over quickly.

He screamed as he ran, and the grass on both sides of the road was pushed to the sides by his huge body.

Some trees as big as bowls could not withstand his impact and broke into several pieces.

"Um?"

Chen Yu hadn't come to his senses yet. What on earth had this guy done to cause trouble?

Chen Yu had always known that She Er's bad behavior would get him into trouble sooner or later, but he didn't expect that he would suffer retribution so soon. "Why are you running? I'm here. I'll hold up the sky for you if it falls!"
