The sun shines down, and the scorching temperature rises.

This kind of heat makes it easy for people to imagine the world as a big furnace, and people are like ores being tortured in the furnace.

Some people with more developed imaginations would even worry about whether they and others would be melted by such a high temperature like the ore in the furnace...

Under the shade of a tree, Han Youli was busy working with sweat all over his forehead.

His body was already soaked with sweat, but his movements did not hesitate at all and he was still busy at a rapid pace.

While he was busy, a clay stove with a diameter of about one meter and a height of more than one meter was made.

After finishing it, Han Youli didn't even take a break. He went to the side and brought back a lot of firewood, put it in the newly built clay stove and lit it.

This is to dry it as quickly as possible so that it can be put into use.

After lighting the fire, adding enough firewood and making sure it would not go out in a short time, Han Youli walked hurriedly under the scorching sun and came to the pile of coal piled there.

He picked up a shovel that was lying there and began to shovel coal into a wheelbarrow.

After shoveling inside twice, Han Youli stopped what he was doing.

He stood here and thought for a while, then took out the coal that he had just loaded into the cart.

Then he put the shovel aside and stopped using it. Instead, he started loading coal stones onto the wheelbarrow with his hands.

He picked the larger ones.

This is also the biggest reason why he gave up the shovel and started to load it directly with his hands.

When using a copper shovel, even if you control it carefully, some small pieces of coal will still be shoveled up and loaded onto the truck.

If you install it by hand, you don’t have to worry about this problem at all.

The weather is hot and the sun is scorching.

These coals have been exposed to the sun for a long time. In addition, they are extremely black. The black is extremely pure and they absorb heat very well. So they feel hot when you touch them.

Even though Han Youli's hands were covered with thick calluses, he could still feel the scorching temperature.

But he did not stop. On the contrary, his speed became even faster. As soon as the large piece of coal touched his hand, he picked it up and threw it into the cart.

In a short while, the cart was filled with coal.

Han Youli, whose hands were pitch black, held the handle of the cart and trotted towards the place where he had just made the stove.

When he arrived here, the fire in the stove had become much smaller. Han Youli did not dare to stop and quickly put down the cart to add firewood into it.

Only after adding all the firewood did he help but let out a long breath, took the water gourd beside him, pulled out the cork and poured in a large amount of water.

After being busy until this time, he was finally able to sit down and rest for a while.

There is a reason why Han Youli works so hard.

The most important thing, of course, is to verify the ideas in one's mind as soon as possible and strive to advance the iron smelting technology in the tribe to a higher level as soon as possible.

Able to make better iron and iron tools faster.

Secondly, I was grateful and touched by the arrangements made by my second brother.

After learning about his idea, the second brother, who is now the person in charge of the Tieshan residential area, not only did not laugh at or scold him, but instead gave him a vacation directly, so that he didn't have to do what he was doing before and could verify his idea with peace of mind.

Such arrangements and treatment made Han Youli particularly excited.

This is the excitement of being trusted and recognized by others.

So he was holding back his energy.

That is to verify your idea as quickly as possible!

No matter whether the subsequent result is good or bad.

After verifying it, you can continue with your previous work and delay your work as little as possible.

With this thought in mind, Han Youli sat here and rested for a while. When he saw that the fire in the simple stove was becoming less strong, he stood up again and added firewood into it.

After adding the firewood, he did not continue to rest, but picked up the shovel beside him and started digging the soil. After digging for a while, he carried the pottery jar to a distant place and brought back two jars of water. He poured the water on the shoveled soil and started to mix the mud.

By the time he had mixed the mud, the firewood in the mud stove was almost burned out.

Han Youli felt it and when he felt that the inside of the clay stove was already hard enough for use, he stopped adding firewood.

He stood here and waited for a while, until the fire was completely extinguished. After thinking for a while, Han Youli used a copper shovel to shovel out the charcoal and other things inside the stove and put them aside.

Then he began to use his hands to pick up the coal blocks that had been pushed in by the wheelbarrow and place them inside one by one.

After filling it up, Han Youli began to scoop up the mixed mud and seal the top of the stove.

Only a hole about the size of a bowl was left at the very top.

After doing all these things, he took a deep breath, lit some branches with the charcoal that he had just shoveled out and had not yet been completely extinguished, and then put these branches and charcoal into the sealed mud stove through the gap at the top.

Compared with firewood, coal itself is difficult to ignite, let alone ignite under such circumstances.

Han Youli tossed it back and forth for nearly half an hour before he finally managed to light it.

After lighting it, Han Youli paused here for a while and turned back to the tribe's kitchen.

First, he washed his hands, feet and face thoroughly with water. Then he came to the pottery jar under the shade of the tree, lifted the lid on it, scooped up a ladle of cooled water boiled with lotus leaves and drank it all in one gulp. Then he filled a gourd of water into the water gourd he carried with him, covered the gourd with the lid, and left, returning to where the stove was.

There was smoke rising from the top of the stove, and sometimes the smoke was a little yellow in color.

Along with it, there was also some rather unpleasant smell.

Han Youli came here, put the gourd in his hand aside, and began to observe the burning of coal in the furnace.

After seeing the flame from the hole on the top, he lay on the ground and checked the holes around the bottom of the stove that were close to the ground one by one to see if there were flames burning in these holes.

Before the flames reached these places, Han Youli sat down against a tree and waited quietly.

This is what he came up with.

The method used is also the simplest charcoal burning method in the tribe.

The source of his idea and inspiration was very simple - ordinary wood could not be used to smelt iron, copper and other things because the temperature was not high enough. However, after it was turned into charcoal through some means, it could do things that were not possible before.

Coal itself is very easy to use. Before experiencing these things, its performance was even better than that of charcoal. So if I use the same method on coal once, will coal become even more easy to use like wood?

Now that coal has become easier to use, when it is used to smelt iron, can the speed be increased a lot?

Han Youli sat here thinking about these things. The more he thought about it, the more excited he became. He couldn't wait to know the outcome of this matter.

Want to verify whether this matter is really as he thought!

After a while, Han Youli stood up from the ground again, walked to the stove, and lay on the ground to check.

The flame still did not burn down.

Although he felt extremely anxious, he still had to be patient and wait here.

"Do you think he can come up with anything good?"

"Who knows? He has done it so many times before..."

"How is this possible? He is not the Son of God, nor is he one of those smart people in the tribe. He is just a person like us. He simply doesn't have that kind of brain..."

"He thought of a good idea to burn coal the same way as burning charcoal? This guy is crazy about becoming famous. Coal is coal, not wood..."

At a certain distance from Han Youli, some people couldn't help but speak, whispering, and pointing at Han Youli who was busy.

Their words were full of disapproval of Han Youli's behavior, which was different from theirs, and even revealed a hint of sarcasm.

In their perception, people should do their duties, and people like them should do the same or similar things as them. They should not do things that are unrealistic or completely different from them.

Such people and such mentality are never lacking in any era.

Han Youli didn't know these things, but he had felt some of them over the past few days.

This made him retreat a little at times, but his love for some things made him ignore these people and continue to work hard towards what he wanted to do.

As the sun was setting, as Han Youli was waiting expectantly, the fire finally spread down from above.

He lay on the ground and watched carefully. When he found a hole that turned red and he could see the fire inside, he would use a large ball of mud to seal the hole tightly.

This process lasted for about half an hour before he sealed all the holes one by one.

After blocking the hole at the top of the furnace, Han Youli sat there staring at the furnace, or what could be called a kiln, in front of him, in a daze, feeling both excited and nervous.

Full of reverence, yet also somewhat uneasy.

But you must succeed!

He secretly clenched his fists and thought this in his heart.

If I fail, I will have let down my second brother.

Moreover, those who often work with me should laugh at me and talk about me again...

Time passed by little by little and night gradually fell.

Due to the special nature of the work here in Tieshan residential area, there are still people working under the light in many places at night.

But the people who work at this time are no longer those who work during the day.

These people have been replaced at this time.

Many people came to Han Youli.

In addition to the second senior brother, there are also those people who work with him and whom Han Youli doesn't want to see.

Because these people always like to give him advice and make fun of the things he likes to do when they have nothing to do.

However, because Second Senior Brother, the manager of Tieshan Residential Area, was here this time, these people did not say anything unpleasant this time.

But there were too many of them, and some of the expressions they revealed unintentionally, still made Han Youli feel uncomfortable and unhappy.

“You can open it and take a look.”

After a while, Han Youli secretly gritted his teeth, pushed aside all the distracting thoughts in his mind, and spoke like this.

Whether it succeeds or not, you always have to see the results. Even if you can’t see it today, you will still have to see it tomorrow.

These people will say unpleasant things and laugh at themselves as usual.

"Then open it and take a look."

The second senior brother next to him also said with a smile.

Seeing this, all the hesitation in Han Youli's heart disappeared.

He took a long breath secretly, walked to the sealed furnace, knocked open the upper layer of the kiln with a copper shovel and pushed it aside.

As the sound of something falling to the ground was heard, the entire small kiln opened.

The second brother held the torch in his hand close to the cracked kiln to see what was going on inside.

The kiln, which was originally full, now had a lot of things missing, leaving only about three quarters of it.

There is not much change in color, it is still pitch black.

There is some dust in some places.

Just seeing this scene, Han Youli couldn't help but let out a long sigh.

What he feared most was that after opening the kiln, he would see that the coal that had been put in would be completely burned, leaving only some coal ash.

He reached out his hand to test it and found that the coal blocks that had been processed by the charcoal burning method were not very hot, so he picked up a piece with his hand and held it up.

As soon as he got it, Han Youli felt the difference between this piece of coal and ordinary coal.

This piece of coal is obviously lighter than the previous ones.

If you look closely, you will find that there are many small holes on the coal.

Han Youli looked at the thing in front of him and for a moment he didn't know whether he had succeeded in making it.

After all, he had never done these things before, and the people in the tribe had never done these things before.

The second brother also picked up a piece of burnt coal between his fingers and looked at it.

"Tomorrow, we will use this coal to smelt a furnace of iron and see how it works."

After a while, the second brother said...
