The scorching flames were jumping in the blast furnace.

Even though he was far away, Chen Zheng could still feel the temperature in the furnace.

Today is the first time he has been here to take off his clothes since he has been here.

However, although it was so hot, he just thought about it and didn't really take off his clothes based on his reason.

The thick furnace made of mud bricks emitted bursts of hot radiation, which made Chen Zheng's face flush. However, although his face was so hot, the back of his head was still cold, and the sweat beads hanging between his hair were frozen into small ice particles.

Chen Zheng held the handrail and regretted while stepping on the pedal hard.

If he brought the helmet, the back of his head would be cold now. Leathers say that if there are handrails on the front and back of the pedal, at least he can turn around and bake the back...

After a long period of suffering from the heat and heat, suddenly, a red light attracted his sight.

Copper is out!!

Chen Zheng was shocked.

I saw that the location of the blast furnace discharge port was like magma liquid slowly flowing out of the V-shaped mud nozzle, slowly filling the sand molds.

After condensation, they will become metal ingots of the same shape and size.

After continuing to step on the bellows for a while, until no copper water flowed out, Chen Zheng jumped off the pedal and excitedly looked at the fruits of his hard work.

The copper water that flowed out initially dimmed, revealing a somewhat reddish metallic color. In such weather, the copper ingots would not be able to completely cool tonight.

The charcoal in the blast furnace was burned out, and Chen Zheng also opened all the vents, but even so he waited for a day and a night before completely cooling down...

After cleaning the furnace and repairing the lower inner wall slightly, Chen Zheng took out a large amount of slag and residual carbon.

Although copper smelting was for superconducting experiments, Chen Zheng had another thing to do before this.

He wants to build a house.

Originally, his plan was to build a small house after exploring the surroundings. Later, the plan was changed because of Yu Shuijing's incident, which allowed Chen Zheng to sleep for more than a week.

After all, the snow cave is a means of survival. Although it can maintain a temperature above zero to a certain extent, it is too simple after all. It is OK for a short period of time. No one can stand living in such a place for a long time.

At the beginning, Chen Zheng’s idea was to build a snow house.

Use compacted snow to cut out large and small snow bricks, then fall the snow bricks one by one like building a house, and finally close the dome, which is like a smirk in the cartoon.

Such a snow house is much better in keeping warm than a snow cave. It can even make fire inside. I heard that it can even reach 18 degrees above zero and will not melt. I don’t know if it is true.

But things like Ice House are still a bit simple after all.

If Chen Zheng’s physical strength cannot be supported, it’s just that. Since you have this condition, why do you have to make do with the Ice House?

Chen Zheng has done the charcoal burning and kiln construction independently these days, and he has dealt with heavy logs every day. Although it is not easy every day, he has done everything after all.

Chen Zheng is still willing to spend more effort to improve his living conditions.

Needless to say, the benefits of wooden houses are good, but the project volume is indeed very large. After several days of experience in building carbonization pools and blast furnaces, Chen Zheng also had some new ideas about wooden houses.

First, he chose a gentle slope far away from the shore. After cleaning up the snow on the surface, he dug out a one-meter-deep foundation. He first lighted a few fires inside to dry the foundation.

The hard frozen soil first became soft under the barbecue of flames, and then the white water vapor gradually became forced out of the frozen soil by the flames. Finally, the entire land in the foundation pool was roasted dry and hard.

After the fire was extinguished, Chen Zheng evenly spread the residual carbon and wood ash on the ground, then made some charcoal and ground it into carbon slag, and evenly spread it on the foundation.

This work alone took Chen Zheng two days.

The slag cleaned out of the blast furnace was not wasted, and it was directly spread to the dug foundation. Dry soil was spread on the slag, and a layer of slag and charcoal were spread on the dry soil. Then it was spread up layer by layer, and the foundation at the last meter-deep depth was almost filled.

In this way, the basic part is completed.

Originally, Chen Zheng wanted to lay a layer of lime, sulfur, etc. below, but due to the limited conditions, this is the case.

Push the carbonized wooden piles into the ground one by one, and then spread the cut thick wood floors on the wooden piles.

Originally, Chen Zheng planned to use mortise and joints on these floors, but now there is no need to worry about having copper. Chen Zheng directly made some copper nails with red copper, and nailed the thick wooden floor neatly on the wooden stakes one by one.

With Chen Zheng's hard work, the foundation of a wooden house gradually took shape. Most of the floors in the house were covered with floors, leaving only the kitchen and bedroom parts with other plans.

In the kitchen, Chen Zheng directly compacted a thick layer of dry soil and carefully slapped a stove.

It was made of stones collected by Chen Zheng, and it was slit with the mud of bone meal. The lightsaber was tamped with shape. After the stove was built, it was neat and beautiful.

A flue is connected behind the stove, which leads directly into the bedroom. Except for the bed where the bed is laid, the floors are laid in other places in the bedroom.

Above the flue, Chen Zheng built a hollow soil bed with adobe bricks, then built wooden stakes along both sides of the soil bed, and covered the bed board with the soil bed.

In this way, when the stove in the kitchen next door is lit, the hot smoke will flow along the stove into the hollow soil bed. After heating Chen Zheng's bed, hence entering the chimney in the center of the house along the flue on the ground, heating the air inside the house again before being discharged from the house.

After the ground is finished, the wall will follow.

Chen Zheng cut the thick wood into ""-shaped large materials of the same size, stacked them into wooden walls one by one, and the cross-section looks like "V" characters stacked together.

In this way, due to gravity, the entire wall will be very strong even without rivets. In order to prevent possible storms or other bad weather, Chen Zheng also used thicker columns in the house to strengthen the vertically.

After the wall is completed, it will be the most important project of the entire wooden house - the upper beam.

Even though Chen Zheng is extremely powerful now, it still took him a whole day to go up the beam. It took Chen Zheng a lot of time to hang the beam, killing a lot of brain cells. In the end, he used ropes and pulleys to pull up little by little.

Hang up the beams, put up the rafters, and then start laying the tiles.

The cross-section of U-shaped shingles overlaps forward and reversely. Each shingle has been carbonized, and one piece of them overlaps forward and reversely, forming this fish-scale black roof.

With the walls and the roofs, Chen Zheng stood in the middle of the cottage with great success, and suddenly felt a little smell.
Chapter completed!
