Wang Yang blew a breath at the rising small flame. The flame thrived and spread to all directions, rising among the chocolate-colored mud bricks, and soft fire tips emerged...

This is a technical job, and the refining technology in later generations has developed to an extremely complex stage.

Wang Yang would not. He, like the first batch of brick-burning people in history, slowly explored the world.

He didn't know what would happen, nor did he know whether the first group of people who discovered the bricks were intentionally done or unintentionally promoted.

He only knows that he is doing it and is working hard for it.

Because of hard work, focus and no giving up.

The temperature of the flame is not high, and the red fire is grilling the charcoal vigorously. If you want to ignite it, no matter how hard you light it, you can only make the charcoal appear a little bit of sparks, and there is no sign of burning.

The temperature was not high enough, and Wang Yang knew this very well, so he waved to the adults holding the broom.

The broom was made of a large number of needles, which was very sparse. Later, Wang Yang collected leaves in the forest and processed them to make them into a dense broom.

The wind was swept, and the protruding air blew into the flames.

"Huh ~" The flame roared, and at that moment it became terrifying, and the hay burned rapidly.

Wang Yang kept adding hay to the fire to the fire, quietly waiting for the charcoal to change.

At this moment, the charcoal changed significantly soon after, and reddish Mars appeared on the outside, and a ball of blue and red flames flashed, and the charcoal was caught.

Wang Yang signaled everyone to continue fanning, in the constant wind, the temperature of the charcoal rose, and Wang Yang, who was standing by, seemed to face the sun, sweat kept flowing down.

He refused to take a step back and kept adding charcoal to it. While maintaining the flame temperature, he hoped that the temperature could reach a higher temperature.

In the absence of a kiln or a closed environment, the temperature of the charcoal cannot be preserved and evaporated in the air, making it difficult to effectively and quickly increase the temperature.

The temperature of the burning brick needs to reach a very high temperature depending on the required function and quality.

Not to mention too much, Baidu should have it, and no matter how low the temperature is, the quality of bricks will naturally decrease.

Maybe it's not called brick, but Tao.

Wang Yang was thinking, what would the ancients do if they discovered that they could burn bricks for the first time? Their conditions must be much simpler than themselves. What can the bricks they burned for?

As I thought about it, steaming steam emerged from the mud bricks.

The air-drying and sun exposure in the previous few days only allowed the moisture on the surface to evaporate, but the moisture inside was still not removed. It rose at this moment.

Wang Yang narrowed his eyes and made everyone increase the strength of the fan.

After slapping for a long time, everyone was a little tired, and the speed of the slap slowly slowed down. Wang Yang quickly asked the others to take over and continued to maintain the wind speed.

He dared not neglect the temperature of a brick forming is very high. Without a closed condition, he can only rely on the speed of the wind to speed up the energy evaporation of the charcoal and maintain a higher temperature.

Even so, Wang Yang suspected that he could only stay at around 600 degrees. This should be the limit, and he was very unsure.

What kind of brick can be burned out at such a temperature? I'm afraid it's not satisfactory.

Because of this, when Wang Yang designed these bricks, they were smaller and thinner than modern ones to ensure the transmission of temperature.

As the water vapor rises, the surface of the mud bricks undergoes slight changes, and the surface slowly becomes rosy, as if it is stained with flames. The small red dots do not appear at the same time, but appear little by little like particles, and then slowly gather and connect, just like rain slowly gathering into a river.

Wang Yang's eyes lit up slightly, and there was a change.

After adding some charcoal to it, Wang Yang took the initiative to take over the next shift fan and fanned it wildly.

After burning like this, it took a whole day. After a few rounds of change, Wang Yang went up and slapped him three times.

As soon as I was replaced, I went to add charcoal and stared at the bricks with my eyes tightly, never leaving for a moment.

The bricks lived up to expectations, and all the surfaces turned dark red, perhaps because they were dyed a little dark by the ashes of charcoal, unlike the bright red bricks I had seen.

He didn't know whether this was a good thing or a bad thing. It might be because the temperature was not high enough, or it might be different from the clay raw materials used in modern times.

The others were tired for a day and watched for a day. Under the night, Suo no longer lit the bonfire and gathered here. He carried the bone spurs from afar, skewers of the meat and sent them to the barbecue.

This method is obviously not a good method. Everyone was blown by the heat wave and wanted to peel off their skin. It seemed that it would not be cool enough if they were not like this.

The meat was not roasted well, and the heat quickly swallowed the outside and burned the meat, but the inside was not hot yet, so the one who served was speechless.

Wang Yingying roasted a piece of pretty good meat and gave it to Wang Yang.

Wang Yang's face was dark and his hands were also dark. From time to time, he felt itchy on his face, and then he applied it. He took a large amount of charcoal at will, and his eyes never left the brick in front of him. He chewed a few bites mechanically, added a few pieces of charcoal, and chewed a few bites.

Just looking at it, I knew that he was not in the mood to taste the taste. He was completely full of food. He was completely crazy. On his dark face, he had a pair of blood-filled eyes that were still motionless, with a focused expression, and looked dull and silly and cute.

No wonder Xiaohong and the others always want to kiss him, so they should kiss her cute look.

Thinking of it, she looked around vigilantly, seeing if there was any woman who didn't know how to see him, and sat behind him, helping him catch lice while not letting others disturb him.

She didn't know what Wang Yang was doing, but it was definitely something very important to the tribe.

After catching it for a while, she lay on Wang Yang's back and fell asleep.

The progress of burning bricks did not stop, and it was impossible to stop. The adults stayed up late and were very tired. Wang Yang wanted to go up and slap them for a while. When his body moved, he suddenly found that Wang Yingying was leaning on his back and sleeping soundly.

She slept peacefully, felt Wang Yang's movements, and unconsciously tightened her arms and wrapped them around him.

"Well... it's a problem to have a sister." He said so, but he did not get rid of it, but adjusted his posture and continued to pay attention to the progress of burning bricks.

The brick burned for another day, and Wang Yang never slept. Whenever his head was shaking, he slapped himself and muttered in his heart: "Take out the status of the college entrance examination!"

The bricks did not change again during the whole day. Wang Yang thought that it might not change, so he asked everyone to stop and no longer fan.

Everyone was very tired, but they all took turns to rest. Wang Yang was even more tired than them. He didn't close his eyes for two days and one night. The drive away could not help but bring him a bowl of water and asked him to go to bed.
