The scorching flames jumped in the blast furnace.

Even from a distance, Chen Zheng could still feel the temperature in the furnace.

For the first time in all these hours of coming to this planet, today was so hot that he wanted to undress.

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

The thick hearth piled up with mud bricks emitted bursts of hot radiation, which made Chen Zheng's face red. But although the face is hot like this, the back of the head is still cold and cold, and the beads of sweat hanging in the hair are frozen into Xiaoice particles.

Chen Zheng held on to the handrail and regretted it while pressing the pedal.

If you bring a helmet, the back of your head is cold now. If there are armrests in both the front and back directions of the pedals, at least he can turn around and roast the back......

After a long time of tormenting in hot and cold, suddenly, a red light attracted his attention.

Out of the bronze!!

Chen Zheng's spirit was shocked.

I saw the position of the blast furnace outlet, like a magma liquid slowly flowing out of the V-shaped mud mouth, slowly filling the sand mold with pieces.

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

After continuing to step on the bellows for a while, until there was no copper water flowing out, Chen Zheng jumped off the pedal and looked at the fruits of his hard work with great enthusiasm.

The initial copper water had dimmed, revealing a somewhat reddish metallic color. In such weather, the ingots will not need to be completely cooled down tonight.

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

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

Although copper smelting was originally for superconductivity experiments, Chen Zheng had another thing to do before that.

He's going to build a house.

Originally, his plan was to build a hut after exploring the surrounding area, but later changed his plan due to the strange fish crystal, allowing Chen Zheng to sleep in the snow cave 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, but it is too simple after all, it is okay for a short time, and no one can stand living in this kind of place for a long time.

At first, Chen Zheng's idea was to build a snow room.

Cut large and small snow bricks from compacted snow, and then drop them one by one as if building a house, and finally the dome is closed, so that the snow hut similar to the Eskimo in the cartoon is completed.

This kind of snow room is much better than the warmth of a snow cave, and it can even make a fire inside, and I heard that it can even reach minus 18 degrees without melting, but I don't know if it's true.

But the SnowRoom is still a bit rudimentary after all.

If Chen Zheng's physical strength can't support it, then it's okay, since he has this condition, why do he have to use the snow room to make do?

In the past few days, charcoal burning and kiln building have all been completed by Chen Zheng independently, and he has been dealing with heavy logs every day. Although every day is not easy, he has done it one by one.

Spend more effort to improve his living conditions, Chen Zheng is still very willing.

Needless to say, the benefits of a wooden house are significant, but the amount of work is also significant. After a few days of experience in building carbonization ponds and blast furnaces, Chen Zheng also had some new ideas for wooden houses.

First of all, he chose a gentle slope far from the shore, cleared the surface snow, dug a one-meter-deep foundation, and first lit a few fires in it to dry the foundation.

The hard frozen soil first softened under the roasting of the flames, and then the white water vapor was gradually forced out of the frozen soil by the flames, and finally the entire foundation pool was roasted dry and hard.

After the fire was extinguished, Chen Zheng spread a layer of residual carbon and plant ash on the ground, and then made some charcoal to grind it into carbon slag, and spread another layer evenly on the foundation.

This work alone took Chen Zheng two days.

The slag removed from the blast furnace is not wasted and is laid directly into the dug foundation. The slag was covered with dry soil, and on top of the dry soil was a layer of slag and charcoal, and so on and so on, layer by layer, until the last meter of the foundation was almost filled.

In this way, the foundation is considered complete.

Originally, Chen Zheng also wanted to spread a layer of lime and sulfur underneath, but limited to the conditions, it could only be so.

The carbonized wooden stakes are driven into the ground one by one, and the thick wooden floors that have been cut are laid on the wooden stakes.

Originally, Chen Zheng was going to use tenon joints for these floors, but now that he has copper, Chen Zheng doesn't have to bother, and directly made some copper nails with red copper, and nailed the thick wooden floors neatly to the wooden stakes one by one.

With Chen Zheng's hard work, the foundation of a wooden house gradually took shape. Most of the floor of the house is floored, except for the kitchen and bedroom.

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

It was made of stones collected by Chen Zheng, and the thin mud of bone meal slipped through the cracks, and the lightsaber trimmed its shape, and the stove was very neat and tidy after it was built.

Behind the stove is connected is a flue, which leads directly into the bedroom. The bedrooms are floored except for the slag where the bed is located.

Above the flue, Chen requisitioned a hollow earthen bed with adobe bricks, then drove wooden stakes along both sides of the earthen bed, and covered the bed board against the earthen bed.

In this way, when the stove in the kitchen next door is on fire, the hot smoke will flow down the stove into the hollow earth bed, and after Chen Zheng's bed is hot, it will enter the chimney in the center of the house along the flue on the ground, and heat the air in the house again before it is discharged from the house.

After the ground is done, then the wall is followed.

Chen Zheng cut the rough wood into large pieces of uniform size, stacked them one by one to form a wooden wall, and the cross-section looked like a "V" stacked together.

In this way, due to gravity, the entire wall will be very strong even without rivets. In case of possible storms or other bad weather, Chen Zheng also made the house longitudinally reinforced with thicker columns.

After the walls are completed, it is time for the most important work of the whole wooden house - the upper beams.

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

Hang the girders, erect the rafters, and then start laying the tiles.

Pieces of U-shaped wooden shingles with a cross-section are overlapped positively and negatively, and each piece of shingles has been carbonized, and one bite and one piece are overlapped positively and negatively, forming this fish-scale black roof.

The walls were there, the roof was there, and Chen Zheng stood in the middle of the hut quite accomplishedly, and suddenly felt that it seemed to have a little taste.
