The supporting iron-smelting workshop was built according to the plan every day, and the fate of all the masonry was manipulated, and when the dark clouds and wind hit, it was basically completed, and then it snowed. Pen ~ fun ~ pavilion www.biquge.info

Man can control the fate of masonry, but man's own fate is sometimes really difficult to fathom.

Just like when the wooden tablet that Ji Yun was anxious to show his skills after the snow was sent back to Yucheng, it was the happiest time for Jian Chen in the past few months, so he was so excited that he capitalized three to show his mood in the back.

If it weren't for the fact that the iron smelting furnace was delayed until the end of winter to complete the construction and asked for ore early, I was afraid that Ji Yun would be scolded, at least he didn't complete the task.

If it weren't for the fact that the workshop workers had already gone on strike once, so that Jian Chen didn't need to focus on the island for the time being, I was afraid that Ji Yun's wooden tablets would not be so valued.

If it weren't for the fact that there was such a big sabotage accident in the farm before, so that Jian Chen urgently needed to find a positive model to promote, I was afraid that the praise Ji Yun received would not be so exaggerated.

Of course, the most important thing is that on the day the wooden tablet was delivered, the people on the island noticed that Jian Chen was very happy. After some inquiry, many people learned that it was the small department called "Bud" that completed one thing that Chen Jian gave them.

A very strange thing that these people couldn't understand at all - Chen Jian asked the old Chinese people in this department to make two things before the snow.

A perfectly regular cylinder about one and a half steps long, about three inches in diameter.

A ball with the same diameter as a cylinder must also be regular.

Wood can be seen as a simple cylinder, but it is absolutely irregular; Centrifugal potter's wheels can also make simple cylinders, but they only look regular, but they are actually of different thicknesses.

As for the ball...... What looks like a ball is not necessarily a ball.

These old people thought about it for a long time, and they didn't understand what this kind of cylinder was for, but since it was Chen Jian's request, they also dug out their minds to ponder.

Until the day of the snow, several children were building snowmen in the snow and were using a pottery ring to pick the snow, and an old Chinese who made wax models in Xia Cheng suddenly thought of a way.

He found a large amount of beeswax, and then used the compass to draw a circle, and then used the three-mode principle of Tiefan that he learned before to make a hollow bronze ring, and after accurate hand-kneading, he measured it many times with the compass circle ratio, and finally determined that the hollow bronze ring was a near-perfect circle.

Then a large amount of beeswax was melted into a thicker wax column, the bronze ring was stuck from top to bottom, and a nearly perfect cylindrical wax model was cut by hand in two days by using vertical hanging line alignment.

It is then wrapped in fine clay on a wax mold and waited until the clay is dry.

Until the night before Ji Yun sent the wooden tablet back to Yucheng, the thick clay had been wrapped in the wax mold and dried, and there were no cracks, and then the heat melted the wax, and a perfect hollow cylinder mold was completed.

As for the ball, the method is similar, using the round plate drawn by the compass to make a round piece, cutting it into a semicircle with a ruler, rotating in the wax model to dig out half a sphere, the two layers of wax mold together to form a hollow, pouring clay into the hollow, and then breaking the outer wax shell after drying, a sphere that is considered perfect in this era has appeared.

Later in the night, these people hurriedly found Jian Chen, and Jian Chen couldn't help but praise a few words, and then told them to make a few more molds, and when the iron was smelted, they would cast a few of these cylinders with iron and choose the most perfect one.

Several people were puzzled, this solid cylindrical iron rod seemed to be useless. Iron was obviously extremely expensive, and the solid iron rod was extremely heavy, and they couldn't figure out what it was used for, but they still did it.

In addition, Chen Jian gave them one more thing: let them go to the supply and marketing department to get some tin, and grind and carve something by hand.

Chen Jian had already drawn a picture of this thing, it was small, round, and thin. On the front is a raised simple black and white bear yin and yang fish, and on the back is a simple ear of wheat, and there is a very simple word. Summer.

Tin is very soft, handmade is also very simple, can be cast or carved and polished, more than ten times easier than jade and the like.

Jian Chen's requirements are not too high, a total of sixteen pieces have been polished, and all of them must be exactly the same.

In addition to these sixteen identical ones, another one had to be polished, more precise than the previous ones, with more patterns on it, the front side was the kind of flower that grew towards the light of the sun, which was familiar to all the great rivers, and on the back was a curved river, which was thicker than the first, as if it was afraid that the metal used for melting and casting in the future would be too soft.

The above requirements are not what needs to be done now, so Chen Jian called that department "bud".

What these thirty people will do in the future are all things that are not needed for the time being but must be made in a few years, Xia Cheng has bronze, brass, gunpowder, high temperature, lead, wrought iron, arquebus, simple geometry, and some things do not necessarily have to follow the history of the previous life, they have to appear when they should be.

After those people left with the drawings and approvals, Jian Chen was extremely excited, the smelting furnace had been basically built, and the final internal repair work was being completed, and everything looked very good.

So much so that when he got up early the next morning, he smiled when he met people, and when Ji Yun's wooden slip was delivered, Jian Chen just had time to take a look.

After watching the beginning, I heard a commotion outside, and several riders from Xia Cheng were carrying some things on their backs, neither holding the flag of emergency, nor any uneasiness and panic on their faces, except for exhaustion, only joy remained.

"What's going on in Xia Cheng?"

"Good thing! Ji Xia, White Horse helped a few weak grassland settlements defeat a large settlement in the autumn and grabbed a lot of horses. Many settlements in the mountains and forests near Yangguan have moved to live near Yangguan, and they help cut a lot of grass in the autumn, and these horses should be able to survive. ”

"The wolf skin in the west led the people to raid a lot of villages in the winter, and a group of old slaves in our city were ransomed with public property, and they swore that they would never betray our city, and the new slaves took the place of those old slaves."

"A lot of children have been born this year, the population is thriving, the old people's health is still good, although the old grandmother is still coughing, but the body is still hard, that is, she needs to lie on her stomach at night, because she always coughs. Your mother gave you two more brothers, twins. ”

"The new army has changed into black clothes, and a while ago followed the white horse in the grassland and made many meritorious deeds, and the horses are all riding well."

"By the way, I also built a few small sailboats, and brought some things to Yucheng for the New Year, some steamed and sealed peaches, not much, one person can share a can, and by the way, the boat will stay here."

"Didn't you ask the company to raise some money to build Yucheng last time? Everyone took out a lot of them, and asked if they wanted slaves here. ”

"Nowadays, the Fang market between the various settlements is also very prosperous, and the Fang market in Yangguan trades with the grassland settlements every ten years, and horses, sheep, and skins can be exchanged for a lot every ten years, and there are some things we have not seen. Let me ask you if this thing is useful. ”

After speaking, the rider took out a leather cylinder from his arms, opened it and poured out some white powder, some wet, some already clumped.

"Where did this come from?"

"Do you remember that the steppe tribes are not short of salt? They had a large salt pan far north, which was brought by the nearby settlements. They use this kind of thing in the grassland, and the company said that they didn't recognize it, so they asked me to ask you. Know if you like these quirky stones or salt. ”

"Nitty?"

Chen Jian touched the feel of the white powder, which was a little slippery, and shouted at the red fish in the room: "Bring the jar of vinegar, and then the jar of spirits." ”

After bringing it all, Jian Chen grabbed a handful of white powder and threw it into the vinegar jar, and bubbles bubbled out in an instant, and the foam overflowed out of the jar along with the vinegar, and the smile on Jian Chen's face became more and more beautiful.

The liquor was dipped in some hemp fibers and ignited, and a pottery stick was found and dipped in a little powder and burned, and the pale yellow color made Chen Jian firmly believe in the judgment.

"Good stuff! How far away is that salt pan? Can you grab it? ”

The rider frowned and said, "I'm afraid I can't, it's five or six hundred miles away, where are so many people guarding there?" There were too many people to make up, and when there were fewer people, they were snatched back by the grassland tribes. There are a lot of these things, but it is a little troublesome to transport them, and a good clay pot and a horse of silk can be exchanged for a lot. ”

Jian Chen laughed and said, "Then don't rob it." When are you going back? ”

"I didn't say anything."

"Then you wait, go back and tell my sister that you may bring back a large number of these things by the plough in the winter, except for the horses, which are the most important, and the sheep and skins will be in the back. Tell the white horse, keep an eye on the movement over there, and if there are big settlements, go to the scourge, and unite those small settlements to rob them. ”

After finishing speaking, he laughed for a while, and he didn't know what he thought, it was rare for people in Yucheng to see Jian Chen happy like this.

And Chen Jian, who was happy to be like this, floated back to his room, unfolded the wooden tablet sent by Ji Yun, and was even more overjoyed, unable to hide the joy of several happy events in the past two days, picked up the pen and commented on the back of the wooden tablet, and wrote three big good words in the dragon and phoenix.

One is to write well, the second is to have good timing, and the third is really good. (To be continued.) )
