The next day, Jiangdian Town.

Li Chu's words played a role yesterday, and there are still a lot of people who come to Jiangdian Town today, and everyone is looking forward to looking at Li Chu and wanting to see what livelihood problems Li Chu said today.

High-tech is also coming.

Yesterday's slap in the face returned to yesterday, Li Chu was so cautious about what he proposed, Gao Xin was also very curious, looking at this Li Chu recently, he never targeted for no reason, since he said so, there must be something big, so he also came to take a look.

Li Chu was the earliest, and he came to Jiangdian Town early in the morning with a team of township soldiers.

The local residents of Jiangdian Town looked at Li Chu coldly, still so hostile and wary.

Li Chu didn't bother with this group of people, and if he wanted to find someone, it was a blacksmith who lived in a vacant lot next to Jiangdian Town.

There is also a blacksmith in Rufen Town, but the conditions there do not quite meet Li Chu's requirements, Li Chu needs a boiler that can burn iron into molten iron, this thing is troublesome to customize, and Li Chu will not operate it, anyway, during this period in the Northern Song Dynasty, there were many blacksmiths with boilers.

The horse blacksmith here in Jiangdian Town happens to have a boiler, which is why Li Chu set the location here.

At the southern entrance of Jiangdian Town, there are several soldiers leading the way at the entrance of the town. From Rufen Town, everyone knew that this was Li Chubing, and gradually many people came and gathered in the open space on the blacksmith's side.

Fortunately, this place is also big enough, able to accommodate a lot of people, let thirty soldiers to maintain order, make a human wall, and separate this book from some distance, the main thing is that the things that Li Chu wants to tinker with are too dangerous, and when the time comes, this group of people will rush in excitedly, which will cause a lot of damage.

In the clearing, there was also a large pile of river sand, which was picked up by more than 30 soldiers in baskets when they came from Rufen Town this morning.

On the ground, there are also five boxy boxes made of wood, divided into upper and lower, with a hollow in the middle, each box is 50 centimeters high.

On the other side of this vacant land, on the side of the house, there is a boiler, and the charcoal fire inside is very strong, and you can feel the scorching temperature inside a little closer.

The blacksmith was loading some scrap iron or small pieces of iron into the crucible, and there was already a crucible burning in the boiler.

Li Chu glanced at the crowd around him, and there were quite a few of them.

Gao Xin, Boss Gao walked to the middle of the field, Li Chu didn't let the soldiers stop him, at this moment Gao Xin and Li Chu were chatting, all of them were some marginal words, and occasionally tested each other, but they didn't test any results.

Gao Xin wanted to ask Li Chu what he was doing, but Li Chu only silently replied with four words: "Just look at it." ”

Looking at the people around him, it is almost the same, and the iron in the boiler is estimated to be almost melted.

Li Chu separated a pile of fine sand, poured some water into it, moistened the sand to the extent that it could be pasted into a block, and then stopped, and then took one of the square boxes.

This box, called the sand mold, has two layers, connected by hinges, Li Chu opened the upper layer, poured the sand into the mold with a shovel, filled the lower part of the mold, and pressed it slightly.

When Li Chu made this thing, he also deliberately placed the mold in the middle so that the surrounding crowd of onlookers could see it clearly.

"Didn't you say that there is something about everyone's livelihood today, what is Brother Chu doing?"

"I don't understand, it looks like I'm tinkering with something."

"Shazi, Brother Chu brought sand all the way here, what is this for?"

In the crowd, some people were talking and discussing each other, but they were all confused by Li Chu's actions, if it weren't for the fact that Li Chu brought a team of soldiers to maintain it today, looking at the formation as if they were very serious, otherwise some people would have left impatiently.

Gao Xin was even more curious, he stood next to Li Chu and saw it more clearly.

Li Chu's movements didn't feel like he was discussing issues such as everyone's livelihood, but more like children playing with mud.

Li Chu started to put sand in the middle of the pressed fine sand with his hands, set out a pit the size of the outline of an iron pot, and then used a sieve to sift some washed sand and adjust the size of the pit in the pit.

This kind of iron pot is the kind of iron pot with a handle and pot on the big stove in the rural homes of later generations, that is, it is several circles smaller in size, and the diameter is 35 cm, which is re-customized from the system.

Li Chu put the iron pot into this pit, then filled it with sand with a sieve and sifted the fine sand on it, and then filled the gaps around the iron pot with the washed sand inside, and finally shoveled in the sand and buried the entire iron pot.

After being buried, Li Chu's whole person stood on this box and trampled on it, tamping the sand.

"How do I feel that everyone has been tricked by Brother Chu, and called the big guy all the way here, just to watch him play with the sand."

"I don't think so, although Xiao Chu used to be a bastard, but Xiao Chu has been very good recently, so he won't joke with everyone on this kind of big right and wrong, and you see Xiao Chu looks serious, where does it look like he's playing?"

"Uncle Li is right, I think Brother Chu is doing this, it must have a deep meaning, you might as well wait, you should be able to know why Brother Chu is doing this."

……

After about that, the sand was gently pushed away, leaking out of the iron pot inside, and then the sand in the iron pot was pulled out, and the iron pot was flat and tamped around, and then the lid was turned up from the side to cover it.

The top cover is the same thickness as the bottom one, and the middle is empty.

Li Chu bent some of the thick iron wire to make a cross, put it inside the upper lid as the inner structure, and then began to bury the wet sand in the upper lid, filling the entire box with sand.

Three soldiers were called, and they stood on it and trampled on it together, and after touching it, they also brought a stone hammer and hammered it vigorously, tamping the sand again.

In this way, a simple sand mold can be regarded as a semi-successful one.

Open the box up and down, the upper half of the upper body of a protruding sand mold is formed, carefully take out the iron pot in the lower half, the lower half is a concave sand mold lower body, Li Chu sprinkled a little lime into the lower body mold, and put the iron pot in and pressed it, and then the protruding mold of the upper body was also sprinkled with a layer of lime, and a sand mold was completely successful.

"Hey, this thing ......"

"Although I can't understand it, this thing made by Brother Chu looks very beautiful."

"I can see a little bit of a doorway, and it feels like a brick factory, like a mold."

"Mold? What is a mold for? ”

Gao Xin was also puzzled, at first at this moment, he would no longer be stupid to think that Li Chu was really playing with sand.

At this time, the iron in the boiler also melted into molten iron after a high temperature of 1,700 degrees.

After removing the impurities on the molten iron, pour the molten iron into the recess of the lower body of the sand mold, and then close the sand mold.

Bursts of white smoke rose from the box, causing the onlookers to be amazed.

After four or five minutes, Li Chu opened the sand mold up and down.

The molten iron has cooled and solidified, and the upper body of the sand mold has also lost its agglomeration at such a high temperature, and it has scattered into fine sand.

When Li Chu lifted this iron pot high......

Gao Xin was stunned.

The crowd of onlookers was also stunned.
