I am a Primitive Man

? Han Cheng looked a little disappointed when he saw the unburned wooden sticks that were revealed after the soil was dug up.

This method really does not burn carbon.

The sticks that were pulled out were very similar to those that were burning and were suddenly extinguished by water. They were all covered with black carbon on the outside, and unburned wood inside.

This thing is far from the carbon that Han Cheng has seen in later generations, and it cannot be called carbon at all.

Although he felt that this method was a bit mysterious before he opened it, he still had some expectations. Now that he opened it and the truth came out, it was inevitable that he would be a little disappointed.

Wu, who stood watching from the sidelines, was also full of disappointment.

He had been expecting last night that there would be some changes in the firewood that was solemnly buried in the soil by the Son of God, and it would be best if more firewood could grow out.

Seeing that the result is actually like this now, he also feels uncomfortable.

I feel that the Kangzhuang road I thought of is far away from the tribe, and there are faint signs of being completely sealed by thorns...

Han Cheng is now a little distressed. He only has a half-knowledge of charcoal firing, and the first attempt failed. He has no good solution for a while.

He looked at the people who were watching him because he didn't know why, and let them continue to do the work that they didn't finish yesterday.

Tietou and others went to harvest the thatch, and the lame and wood cut the wood pieces and burned them in the fire before polishing them.

Han Cheng squatted by the messy fire pit, picked up a piece of blackened wood that was burnt outside, and studied it carefully in front of his eyes, his eyes showed a look of thought.

In this situation, Han Cheng suddenly wanted to recite a poem, which was the famous The Charcoal Seller written by Bai Juyi.

It's not about the difficulty of burning charcoal, the difficulty of sympathizing with the old man, or the indignation about the disturbance of the people in the palace city, but because of this, it reminds me of some experiences of the charcoal seller in burning charcoal.

The charcoal seller cuts firewood and burns charcoal in Nanshan. His face is dusty and smoky, his temples are gray and his fingers are black...

The first two sentences of this article describe the hardships of the charcoal seller burning charcoal, but Han Cheng has seen something else through this layer.

It is his method of burning charcoal that really doesn't work.

Because judging from the experience of the charcoal seller, he is very likely to be a loner, old and weak. If he uses the method Han Cheng used to burn charcoal, not to mention the rest, he will just cover the burning firewood with sand. This is very difficult to do.

Because the covering is slow, these branches are all burned by fire, where will there be carbon?

Han Cheng didn't know what others read from The Charcoal Seller, but he did read from it at this time that his method was not good, although he couldn't explain the reason clearly.

Wu stayed here with Han Cheng for a while, then got up and went back to the tribe. After hesitating for a while, he came to the edge of the rabbit circle, where he lay down and licked the rabbits every day.

It's just that compared with the past, today when he was stroking the rabbit, he seemed a little absent-minded.

Han Cheng squatted there thinking for a long time. When he stood up, his legs lost all intuition. After staying in place for a while, he gradually came out of this sour feeling.

He called Hei Wa, and together they carried the firewood to the clay kiln near the small river.

As the weather gets colder, Hei Wa has not made pottery clay for several days.

Together with Han Cheng, Heiwa put the firewood he was carrying on the edge of the earthen kiln. He couldn't help but feel a little puzzled. The last batch of clay embryos were fired a few days ago. What did Chai come to the kiln for?

Do you want to use this kiln to burn charcoal?

Heiwa is not a stupid person, and he quickly guessed Han Cheng's intentions when he got in touch with what Shenzi had done before.

It's just that the incomprehension in my heart is more intense.

The entire tribe counts him as the one who has dealt with this earthen kiln a lot. The earthen kiln is well ventilated, and after putting in firewood and lighting it, it will burn blazingly.

Now that the Son of God brought so much firewood and put it into the kiln, wouldn't it all be burned? Where can there still be the kind of charcoal that the child of God said...

Han Cheng was also thinking about this matter in his heart, but he didn't have much idea. He could only do a little experiment, looking for experience from repeated failures.

With the help of Heiwa, firewood was placed in the kiln where the mud embryos were originally placed, and firewood was placed in the bottom of the kiln.

The top of the earthen kiln was blocked by two large pottery panels, Hei Wa took out the original fire booklet and blown out the flames, then looked at Shenzi inquiringly.

Han Cheng naturally knew what Heiwa meant, hesitated for a moment, then nodded lightly.

After receiving Han Cheng's confirmation again, Hei Wa didn't hesitate anymore, first lit the dry grass, and then lit the dry wood. Not long after, the matches at the special stove under the earthen kiln were already burning blazingly.

Not long after, the firewood placed in the kiln also started to burn.

So much firewood was burned together, and the fire was very strong. Even though the earthen kiln was covered with pottery panels, the hot flames still came out from the gaps around them, and rose high.

Hei Wa looked at all this, and suddenly remembered that Shen Zi had someone cover the burning firewood with sand yesterday, and couldn't help feeling a little anxious.

After all, this kiln has great uses, and he spent a lot of effort to build this kiln. Wouldn't it be a pity if it was buried like this?

Then he looked back and forth to one side, and found that there were only Shenzi and himself here, and he hadn't brought a bone shovel, so he obviously wouldn't bury the kiln. This made him, who loves kilns, feel relieved.

But then he realized that something was wrong. If it wasn't covered with sand, wouldn't the firewood placed in the earthen kiln be burned out?

Han Cheng had already considered this point before. The combustion of flames requires oxygen, and he still has the most basic common sense.

After looking at the fire for a while, Heiwa was asked to go to the side first and move the broken large pottery fragments and some stones discarded there to the side of the kiln.

After waiting for a while, he asked Hei Wa to use these things to gradually block the fire opening under the clay kiln.

As the burner port shrunk little by little, the air entering inside gradually decreased, and the flame became much smaller without the arrogance it had before.

It's just that the flame inside the clay kiln still hasn't been completely extinguished, which is related to the gaps in the burner hole under the clay kiln. After all, Heiwa used pottery shards to block the burner hole, and it is impossible not to leave some gaps.

Han Cheng also has a tangled face now, don't completely seal the fire, he is worried that the firewood inside will be completely reduced to ashes, seal it completely, and he is afraid that these firewood will be like the one he picked up from the ground today, Half-baked is also uncomfortable.

After struggling like this for a while, I finally decided to burn it like this first, and if it doesn't work, I will seal the burner completely with mud next time.
