Han Cheng's original plan was to wait until the next day to open the kiln, but the kiln was opened in the afternoon.

It's not that he was impatient, but he found through the gap on the top of the kiln that the firewood inside had basically been burned to ashes, and the temperature of the kiln had also dropped, so he opened it early.

Han Cheng took a stick and stirred the earthen kiln, which seemed much emptier. Some ashes that still barely retained their original shape were shattered into pieces.

Han Cheng sniffed, looking helpless.

He asked Heiwa to reopen the sealed fire hole, clean up the ashes, and then carry firewood to load it into the earthen kiln.

After some work to light the fire, he found a bone shovel and a clay pot and mixed a pile of mud.

After burning for a while, Han Cheng asked Heiwa to block the fire mouth again with stones and tiles, and then used the prepared mud to apply a thick layer on it to completely seal the gap below.

After the fire hole was blocked, the firewood quickly went out due to lack of oxygen.

By this time, the sky was gradually darkening. Although Han Cheng was anxious to know the result, it was not a good time to stay outside for long, so he went back with Heiwa.

Nothing happened that night. After getting up the next day, Han Cheng washed himself with hot water from the fire he had boiled earlier. He tied his clothes tightly, put on his hat, and took Heiwa out.

Some people who had nothing to do besides waiting for breakfast to be ready also followed...

Tietou has become more and more hardworking now, which may be related to the fact that Ruhua gave birth to a little Ruhua half a month ago.

Early in the morning, I worked with two people who often cut grass to feed the deer. We used hoes, shovels and brooms to clean out the deer dung in the deer pen, and carried it to the dung pile some distance away from the east side of the wall. These were excellent fertilizers and we couldn't bear to waste them.

Han Cheng originally thought about making a hole in the wall so that he could use a bone shovel to shovel the manure out directly. But he later thought about it and gave up because the wall was too thick and it was difficult to make a hole.

Secondly, the presence of such a hole will greatly affect the firmness of the wall, and this hole is also a safety hazard.

In later lives, he saw many people's cows being stolen through this hole.

It is said that the cattle thieves are very skilled. They can slightly expand the manure opening, which has a side length of no more than 30 centimeters, and pull out such a big cow. Until now, Han Chengdu still doesn't understand how they do it.

Another thing is that the dung pile on the outer edge of the wall will reduce the wall's defensive capabilities. In order to prevent people from climbing up the wall along the high dung pile, we have to arrange special people to take care of the deer.

After all the manure was removed, Tietou used a bone shovel to scoop up some of the "foam" that was piled on the edge of the deer shed and evenly spread it in the wetter areas of the deer pen.

'Mozi' is a mixture of finely crushed dry soil, broken leaves, and grass leaves, and is very dry.

After cleaning the deer pen, sprinkle a layer of it on it to make the deer pen clean and the deer comfortable.

After finishing all these in a hurry and getting some hay for the deer and three lambs to eat first, Tietou and his two companions walked out of the courtyard gate and headed towards the earthen kiln beside the creek, where a lot of people had already gathered.

After a night, the earthen kiln had already become completely cold in such a cold night.

Han Cheng asked someone to open the earthen kiln with some trepidation, and the scene inside the kiln disappointed him again.

Most of the firewood inside was not fully burned. In addition to the half-burned ones, there were many that were not burned at all.

Some of the ones in the center have been completely burned to ashes.

Han Cheng watched for a while, then started to take out the obviously damaged firewood in the kiln and piled it next to the kiln.

Everyone looked at the Son of God's expression, and many of them kept silent. Without the Son of God saying anything, they already knew that the charcoal still had not been burned.

What kind of good stuff is the charcoal that the Son of God is going to make?

With the power of the Son of God, how could he fail so often?

The curiosity of the people in the Qingque tribe was aroused even more.

"Ha ha"

Han Cheng suddenly laughed out loud while holding a piece of black charcoal in his hand.

This piece of charcoal is much lighter near the center than the wood that has not been burned through.

Moreover, unlike ordinary charcoal, which is easily broken, this piece of charcoal still retains its original shape.

To make a not-so-good analogy, it's like a person who suddenly becomes countless times darker. Although the color has changed drastically, you can still tell what he looked like before.

Find a wooden stick and tap it gently, it will make a crisp sound.

This is not much different from the charcoal that Han Cheng saw in later generations!

In addition to this piece of charcoal, there was some scattered charcoal in the transition area between the center and the outside. Han Cheng asked Heiwa to get it out quickly.

Heiwa and others saw that the Son of God looked quite high-spirited and knew that he had some idea of ​​what he was going to do.

Seeing that the Son of God was also happy, they naturally did not dare to delay and quickly took out all the scattered charcoal.

Han Cheng picked and chose, and selected a few unburned pieces and threw them aside. He looked at the charcoal, not knowing whether there was a pound of it, with a smile on his face.

With so much firewood, only such a small amount of charcoal is produced. The efficiency is shockingly low, but it is indeed very good news for Han Cheng.

This proves that his idea is correct, and all he needs to do in the future is to continue to improve on this basis.

Someone in the tribe informed them that breakfast was ready, and Han Cheng carried the charcoal in a small basket and went back with everyone else.

After washing my hands again with warm water, I started eating.

The people of the Qingque tribe now wash their hands more carefully than in the summer because they have discovered the benefits of washing hands in winter and keeping their hands clean.

Before the Son of God came, most of them would have cracks on the back of their hands in the winter.

Not only do these cuts make the dark and dirty hands look even uglier, but the most important thing is that they are painful.

Ever since the Son of God came and asked them to wash their hands frequently, they rarely have cracks on the back of their hands in winter.

Even if one or two people's hands are frozen, it won't be as horrific as in previous years.

Those children who didn't want to wash their hands in winter, after discovering this benefit, started to wash their hands very carefully.

After breakfast, Han Cheng found a brazier, scooped out some charcoal from under the big vat and put it in it, then lit the charcoal from the small basket and checked its quality.

These charcoals are very good and produce almost no smoke when burned.

Because it is always in a dark fire state, it burns very slowly and takes longer than simple firewood to burn.

Han Cheng nodded, found two chicken wings, put them on a thin stick, and grilled them over the charcoal fire. After they were grilled, he gave one to Wu and ate the other one himself.

I took a bite and found it tasted good. It didn't have the smoky smell of the past and was much smoother to eat.
