I really don't want to be a rebel [infrastructure]

Although Cheng Jingwei couldn't understand those complicated terms, he helped solve most of Luo Shixing's problems, especially the kiln car problem.

Luo Shixing felt that the kiln car was a bit difficult to handle, so Cheng Jingwei said calmly, "Use stone."

Anyway, the kiln car that Luo Shixing asked for was not too big. Most of the Ouluo tribe still used stone tools. Their smelting technology might not be very good, but the level of stone tool production was really good, at least better than Datang.

Of course, this is probably because Datang no longer needs to use stone tools, so the technology of making stone tools can naturally be discarded.

Luo Shixing couldn't imagine how to use stones to make kiln carts, but Cheng Jingwei took a few slaves to the quarry to find suitable stones, and hewn a stone cart.

Because it is a kiln car, the requirements for the stone car are not so high, as long as it will not be burned.

Stones are also used for the wheels and axles. Luo Shixing watching them make it is an eye-opener.

In this era without sandpaper, they actually used bark and sand to polish. He had never thought of this way of polishing before.

After all, this kind of technology is really meaningless... It is impossible for future generations to teach it. At most, it will be passed in history class, and it is impossible for Luo Shixing to memorize it.

The only disadvantage is probably that it is difficult to find a particularly large stone to make a stone cart. The final stone cart is only about one meter long and wide, and it is directly square.

Although it seems to have met Luo Shixing's requirements, this is the overall length and width of the stone cart, and the thickness of the car body is included, and what Luo Shixing requires is a long style with internal fighting, so if this kind of stone cart is placed with bricks , can't place much at a time.

However, Luo Shixing was quite satisfied, it didn't matter if he couldn't place much, at most he needed more stone carts, at least they could be used.

What's more, their brick kiln is not that big.

So Luo Shixing stared at the construction of the brick kiln here, while Cheng Jingwei led people to dig stone carts in the wind and rain.

Luo Shixing once went to watch. At first, he thought that the chiseling of stone carts should use more brute force, but he didn't expect that it would require some skills, especially the choice of stones.

It cannot be too hard or too brittle, and shale and the like are directly excluded from the selection.

Luo Shixing didn't have much say in this aspect, and he could tell the characteristics of these stones, but stone tools were super-class existences for him!

He and Cheng Jingwei have been busy for half a month, and the brick kiln and stone carts have been built, and the connected parts in the middle of the stone carts are also connected with hooks made of stones.

After the stone carts were ready, they did not rush to open the kiln. Instead, they placed the stone carts on the track and let the slaves push them forward from the entrance. After the carts came out from the exit, the slaves at the exit Just hook the shackle of the front car with a stone hook with a handle, and then drag it out.

After the first car exits, it is quickly unloaded, and then pushed all the way to the entrance through the side track.

In order to facilitate the entry and exit of the stone carts, the entire track was set in an oval shape by Luo Shixing.

The empty car test went well, the car was fine, and the inside should be fine, and then the loading test was carried out.

Fill the kiln car with bricks that have been dried in the shade before continuing to push in.

This time it can be clearly seen that the push is more laborious, but the advantage over the previous one is that the car has been pushed in before, so the people in front are also pulling the car out with force.

Although labor-intensive, the end result was good.

After confirming that there was no problem with the kiln car track, Luo Shixing took a deep breath and looked at Cheng Jingwei a little nervously.

Cheng Jingwei patted his head: "It's okay."

Only then did Luo Shixing shout: "Light it up!"

The internal combustion chamber is ignited, which means that the first batch of bricks is about to start firing.

Although he had known for a long time that there would be such a day, Luo Shixing still felt a little excited, and this was a big step for them.

It's amazing to think about it. These days, it is impossible to live in a brick house without financial strength. However, now that they are clearly poor, they seem to be able to live in a brick house ahead of schedule. Suddenly, they feel like skipping a grade to study.

I don't know if it was because he was too happy, but something went wrong with the first batch of bricks.

After coming out of the drying room, Luo Shixing frowned when he saw the color of the bricks. He touched the bricks and said, "This...the inside of the brick kiln is not hot enough."

He almost said that the temperature was not enough, but he thought of the word "no temperature these days" when he said it, so he changed it temporarily.

The batch of bricks that came out was a bit whitish in color. Luo Shixing knocked on the bricks and listened carefully, and found that the sound was also very dull.

Cheng Jingwei asked: "What's wrong? Isn't it very strong?"

Luo Shixing shook his head: "No, this brick is a typical underfired brick, and it will happen if the temperature of the brick kiln is not enough."

Seeing Cheng Jingwei's disbelief, Luo Shixing asked someone to bring a stone hammer, put the brick on the ground, hammered it down with the hammer, and then... nothing changed.

Facing Cheng Jingwei's doubtful eyes, he was silent for a moment, then handed the hammer to Cheng Jingwei and said, "Come on, hammer hard, use as much strength as you want."

Only then did Cheng Jingwei realize that Luo Shixing was not strong enough just now, and after taking the hammer, he smiled and said, "Then stand a little farther away."

He was worried that he was too strong, and when the bricks were smashed, pieces would splash out. This was uncontrollable and dangerous. The little lynx was easily injured if it stood close.

Luo Shixing stood aside, then watched as Cheng Jingwei raised the stone hammer and smashed it down forcefully, his head turned around in an instant, and the pieces flew into pieces.

Luo Shixing came over and took a look at the fragments and said, "This is a typical unfired brick."

Cheng Jingwei was also a little worried after hearing this. The inside of the brick kiln is not hot enough, which is very troublesome. He has to change the structure of the brick kiln or change the fuel.

However, both of these are not easy to solve. First of all, there is no way to solve the fuel problem. They can only use pine branches and firewood. But if the structure of the brick kiln is changed, it may involve dismantling the existing brick kiln. There is a high probability that the mud bricks will not be used.

The waste of manpower and material resources is not one or two points.

In fact, Luo Shixing also didn't understand that the structure of this brick kiln was a serious tunnel kiln. He had calculated very rigorously according to various formulas before, so how could the temperature not be enough?

If it weren't for the high temperature inside the brick kiln, he would have wished to go in and see for himself.

He walked around the brick kiln, and he could feel a slight heat wave standing outside the brick kiln. He stood in the part of the internal combustion chamber, looked at it and thought about it, and suddenly understood one thing - the tunnel kiln of later generations is in this part There is a mechanical blower.

The presence of the blower allows the fuel to burn more fully, and their lack of this one thing leads to insufficient internal temperature.

Luo Shixing rubbed his face and said, "Okay, I know what to do now."

Cheng Jing was stunned for a moment: "Huh? Have you thought of a way?"

Luo Shixing said, "Just get a blower and add it."

"Blower?" Cheng Jingwei was at a loss, another word he had never heard before.

Luo Shixing quickly said, "Oh, it's the bellows."

Cheng Jingwei understood this time: "This is quite simple."

In the Tang Dynasty, the use of bellows was very common in smelting and various occasions. Cheng Jingwei was interested in all kinds of swords, guns and sticks since he was a child. A sword that is unparalleled in the world.

It's a pity that what happened later was enough to bury the dreams of all teenagers.

But now he is very happy that he has learned about this matter, and said very generously: "Leave this to me. You have been very busy with this brick kiln recently, so take advantage of these two days to rest."

Luo Shixing thought for a while and tilted his head and asked, "What kind of bellows do you want to make?"

Cheng Jingwei was at a loss: "Is there anything special about this?"

Luo Shixing raised his chin slightly and said, "I know you haven't thought about it that much. Most of the bellows in the Central Plains are manpower. We have unique conditions now. Why don't we do something different to save manpower?"

Cheng Jingwei followed his gaze and asked, "Water?"

Luo Shixing nodded seriously and said: "That's right, there is a kind of bellows called water row, that is, hydraulic bellows. I think the water flow here is not bad, and it should be able to drive it."

Cheng Jingwei was silent, this...was beyond his knowledge.

Luo Shixing didn't say anything, he took advantage of time travel, so naturally he has no right to say that Cheng Jingwei doesn't know much.

He even said: "But since you have volunteered, why not let me go back and draw a picture, and you make a model according to the picture. If there is no problem with the model, continue. Anyway, if you can make a model, you will basically make it bigger. Bellows, come and watch when the time comes."

Hey, recently he has to run so many times for this brick kiln every day, he feels that his legs are getting tired!

Cheng Jingwei heard him put his hand on his shoulder and pushed him back, saying, "Okay, go back and see if the model symbol meets your requirements."

When Luo Shixing and Cheng Jingwei went back, they found that Wei Siwen and Alezhen had come again.

Alezhen not only came here by himself this time, but even brought his three children.

The three little bean dings clasped their fists to salute him very politely. They wanted to bow at first, but they were too young to control their bodies so well, and they almost fell headlong in the middle of bowing.

After hastily supporting the three little bean dings, Luo Shixing nodded with his hands behind his back and said solemnly: "There is no need to be too polite. I still have something to do as a teacher. You can play on your own."

Cheng Jingwei followed behind him and looked at him holding his non-existent belly with his hands behind his back, grinning so obscenely.

After the three little Doudings shouted: "Look at Tutu." After running away, Luo Shixing turned his head and looked at Cheng Jingwei expressionlessly.

However, Cheng Jingwei was too cunning, and quickly restrained the smile on his face, showing a nonchalant look.

Alezhen, who was on the side, realized that he had found an older child as a teacher for the three children, and couldn't help laughing too.

Luo Shixing snorted dissatisfiedly: "What are you doing here? I don't have much time to cook these days."

Wei Siwen and Al really had their purpose exposed, and they blushed immediately.

Oh, Alezhen's skin is a little darker, I can't tell.

He was also thicker-skinned, and just said, "It's nothing, just come here for a stroll out of boredom, and let the three children come over to identify the door, after all, they will study here in the future."

Luo Shixing also felt a little guilty after hearing this. Since the three children became apprentices, he hasn't attended a single class.

He scratched his head and said, "Oh, let them wait a little longer. The brick kiln is almost done, and there is only one problem to be solved. The next thing is to wait for the bricks to be fired, so I can give them lessons."

Alezhen said casually: "Just tell me if you have any difficulties, and I will help you solve them."

Luo Shixing laughed and said, "You really can't solve this."

A Lezhen's eyes lit up instantly when he heard it. Generally, what he couldn't solve meant that the local level could not be reached, so Luo Shixing would definitely come up with more advanced things.

He asked curiously, "What are you going to do?"

He said that because Luo Shixing had already taken out the clay tablet, and he remembered that every time Luo Shixing took out this thing, it meant that he was going to make a new thing.

Luo Shixing responded, "Yes, the inside of the brick kiln is not hot enough and needs to be heated, so I plan to get a hydraulic bellows."

After hearing this, Alezhen was extremely excited, stretched out his hand to hold Luo Shixing's arm, bent down to look at him and asked seriously, "You...you know how to make bellows?"

Luo Shixing was taken aback by him, stared blankly at Alezhen and nodded.

Al really took a deep breath, got up and started circling on the spot, looking very excited.

Luo Shixing couldn't help but quietly took two steps back and walked to Cheng Jingwei's side and whispered, "You...don't do this, it's scary."

After hearing this, Alzhen waved his hands at him and didn't say a word. After turning around twice, he turned his head to look at Luo Shixing and said, "If you can make this... a hydraulic bellows, I'll give you a salt well." !"

Luo Shixing:? ? ? ?
