I am a pirate in Ming Dynasty

The act of lighting a fire becomes sacred and full of ritual.

Marvin and others stood in front of the finished floor heating tunnel. The floor heating tunnel they made was made of mud. After all, there was no hard object when the roof was capped.

Yue Heng on the side used a slightly different method. He found a few large pieces of bluestone and laid them on the passage.

Marven looked at it and couldn't help but mocked: "Yue Heng, are you trying to cover the entire classroom with stones?"

Yue Heng also knew Ma Wen. This guy had been to their class many times and was not very good with their class.

Listening to the other party's sarcasm, Yue Heng's expression remained unchanged, and he opened his mouth and said: "Be yourself, this is all in the experimental stage, how can you be sure that your mud can be directly burned and solid without cracking?"

Marvin snorted and said, "You seem to be able to find so many rocks. Even if you succeed, you still won't be able to complete it."

Yue Heng turned his head and ignored the other party, and tried to turn on the heating through the simple passage.

If the fire is lit from one end, there is no need to seal it. If the three-meter-long channel can successfully transport the hot air, it will be in vain.

The function of establishing a passage is to ensure that there is no smoke leakage. If it is done directly indoors, the house may be blackened and no one can live in it.

The flames were lit, and the temperature in the entire yard seemed to rise.

Ding Xiaoquan squatted on the excavated mound and looked at Yue Heng beside him: "Did we pile it up too easily? I don't think it will collapse easily."

Marvin glanced at the top with a displeased face, looking at the top that was smoothed with mud. He looked embarrassed, so he said in a low voice: "Ugly, it's a bit ugly. At worst, take some time, and don't underestimate us." What if my work is useful?"

Ding Xiaoquan glanced at the dried mud on his hands, imagining how the mud on the ground would look like drying, and suddenly felt a little embarrassed.

Yuan Taotao was the most serious. He wiped the mud for a long time, and his palms were already frozen, and he didn't know how he persisted.

At this moment, Yuan Taotao hoped that it would succeed. The flames rose and a lot of smoke rose in the whole yard.

The villagers lying on the courtyard wall suddenly choked and fell down, and their faces were all gray.

Isshiki squatted outside and coughed, and some students were so moved that they shed tears.

"You have to make a chimney to come out," Marvin said with a thoughtful look on his face.

Among children, not many have this awareness.

Watching the fireworks, some of the children looked thoughtful, while others endured the choking smell.

Yue Heng next to him also suffered greatly. The passage he made was poorly sealed. Even if he tried his best to break it in, smoke still leaked from the gaps between the bluestones.

It is conceivable that if this was built inside a house, wouldn't it choke people to death?

Yue Heng asked others to light the fire while he flipped through the manuscript. The concrete mentioned in the manuscript seemed to be used for the cover, but he had never heard of it.

Yue Heng read the manuscript carefully. Many of the things in it were specious and he had never even heard of them. However, there were annotations in many places, indicating that the things could be found in books.

He immediately said to his classmates: "Don't burn it yet, wait until I come back."

In everyone's surprised eyes, he left in a hurry.

Naturally, Qin Shang would not understand what was happening here, because at this moment he was facing an unexpected person.

"Teacher, why are you here?" Qin Shang asked in surprise.

The man in front of him was dressed in tattered Taoist robes and covered in mud. He didn't know where he came from, but Qin Shang recognized him at a glance with his iconic appearance.

"It's bad luck, don't mention it. I met a weirdo on the way. He has no habit of respecting the elderly at all."

"Forget it, I had a fight with him. The little guy was so angry that he almost gave me a leg."

"Qin Shang, you have been slacking off recently. The energy in your body is not as good as before. It seems that the teacher is not here and your study progress has fallen behind."

Qin Shang shook his head with a wry smile. He is a child and has almost no time to rest these days because of school affairs. It would be good if he could practice Qi every day. It is basically impossible to expect him to be the same as at home.

"It doesn't matter, the teacher is here. From today on, I will help you regain your previous strength."
