Go mining again

Others also looked at Lin Yan eagerly, asking why he couldn't eat the good chestnuts.

Lin Yan didn't show off, and said directly: "The hairy chestnuts have other uses, but they are gone after you eat them. These three hairy chestnuts are very important."

The others looked at each other in confusion, wondering what else could be used for such delicious chestnuts. Shouldn’t the delicious ones be used to fill the stomach?

"The pulp of chestnuts has a high starch content."

Bai Chen exclaimed: "It can be used to make paper."

"That's right. Adding starch to the slurry can be used as a glue to make the paper smoother, wear-resistant, and oil-resistant. This solves many problems." Lin Yan only remembered this when he saw Mao Lizi.

Everyone present was excited. Papermaking encountered obstacles, which forced them to slow down and change their plans. They were under great pressure.

Hua Min immediately said: "So that's it, then these chestnuts really can't be eaten."

"The chestnuts are of great use, but there are only a few of them. Who dares to eat them?" Shi Zhi continued.

Huang Ying blinked, "I'll go to the city to find some more chestnuts. These few are still too few."

"Who can still keep their hairy chestnuts?" Shi Zhi felt that there are too few people like Hongying. Basically, they are all people who eat delicious food as soon as possible.

"How would you know if you didn't look for it?"

Hong Ling said: "There is still more than a month before we can have fresh chestnuts. We should concentrate on smelting iron. When the fresh chestnuts are ripe, we can save some for later use."

Lin Yan nodded, "Hong Ling is right. Let Bai Chen test these chestnuts first. We still have to concentrate on making iron."

Everyone no longer covets chestnuts, they immerse themselves in eating, and then get back to work after eating.

The day passed quickly.

When he came home in the evening and saw Hua Hong, Lin Yan asked, "What did you do today?"

"Clean up that land. Everyone who went there today is doing this. It will be cleared out in a few days." Huahong drank some water and set up the pot to fry the meat.

"I heard that you get paid for your work. How much does Grandma earn in a day?"

"The young and strong laborers are paid 2 cents a day, but the old lady is only given 1 cent."

"That's not bad. I can buy 5 wild eggs."

Huahong nodded in agreement, "Yeah, it's just tiring, but everyone is happy to be able to contribute to Sun City. The smelting plant is for ironwork, and everyone hopes it can be built as soon as possible."

I am in a hurry every day, and June 1st arrives in a blink of an eye.

The office compound has been built, and the five departments and the arbitration tribunal have moved in. With the efforts of countless people, the main body of the smelting plant has been built, leaving only the burning furnace and the smelting furnace.

The results of the laboratory are gratifying. It has created two broad-backed broadswords, three large axes, two spears, three iron bows and arrows, heads, sickles and other tools. It can also make iron wires of different thicknesses. Finally,

The thin ones are 2 mm in diameter and are used as bow strings.

Shi Zhi also made rulers and weights out of iron, using them as measurement standards.

After Hua Min and Shi Zhi's continuous experiments, they made a ceramic model, which is more durable than a clay model and is much more efficient.

When it comes to pouring ironware, the efficiency has improved a lot after having a clay model. The clay model is for one-time use, but the ceramic model can be used several times.

The ceramic mold can be disassembled and assembled. After the molten iron has been poured and cooled, the ceramic mold can be disassembled and used again.

Kurotsuchi's military headquarters has also been established, with 200 people divided into ten squads with squad leaders, and five squads with squadron leaders.

After personally testing the power of broadswords, spears and bows, Kurotsuchi strongly requested that once the smelting plant is completed, a batch of weapons should be produced immediately.

With weapons at hand, the military planned to form a team of people to mine. This proposal was agreed by everyone. Now that everyone has seen the usefulness of iron tools, it is foreseeable that the demand for iron ore will increase greatly.

After seeing the results of the laboratory, the arbitral tribunal immediately made new arrangements, and more people were invested in the construction of the smelter and the firing of ceramic models.

Lin Yan led others to design the iron coins.

It is a hollow circle with an outer circle and an inner square. In order to reduce the difficulty of pouring, only the amount and a sun figure are marked on the coins.

There are differences in the size of different amounts. The 100 yuan coin is the largest, with a diameter of 3 centimeters and a thickness of less than 2 millimeters.

This is not only to reduce weight, but also to save raw materials. Iron is very useful.

After the coin shape is designed, we start designing the pottery model.

After working for more than half a month, I finally got it done, just waiting to pour the iron coins. At this time, the smelting plant was also completed.

On June 18, the smelting plant started working. From that day on, people came and went every day and it was in full swing.

Minting is done jointly by the Finance Department and other departments. The foundry is managed by dedicated personnel and is located in a secret place in the smelting plant. There are anti-counterfeiting marks on the pottery molds, and each batch is different.

Two days later, the first batch of iron coins was minted successfully, all with a denomination of 1 cent, totaling 100 yuan.

This is the first batch of coins from Sun City, which is of great significance. The arbitration tribunal unanimously decided to pay 2 cents to each person who built the smelter first. Let everyone see what the coins look like.

With the first batch, the second batch was quickly made.

The plan for the first coinage is 100,000 yuan. Each of 1 cent, 2 cents, 5 cents, 1 jiao, 2 jiao, 5 jiao, 1 yuan, and 2 yuan will be minted for 10,000 yuan. These small coins are what people need most every day.

5 yuan, 10 yuan, 20 yuan, 50 yuan, 100 yuan each makes 5,000 yuan.

Since iron ore is limited, priority must be given to making weapons, so the first minting will be completed in multiple times.

By the beginning of July, the first batch of ore was used up, and fifty bows, three hundred arrows, twenty broadswords, and thirty spears were made, all of which were distributed to the people in the military department. The rest were made into some iron coins.

and various tools, among which machetes, axes, sickles and heads account for the majority.

Equipped with weapons, Kurotsuchi led one hundred and fifty people on the road to the mine again.

Most of them were people who had been there last time, and the rest were selected from people in the military department.

The whole city stood on the central avenue, watching the mining team set off. Although they had already gained experience and brought back ore, and the equipment was greatly improved this time, every time they went out, they were worried.

Lin Yan was still on the list. She strongly requested to go, but the others couldn't resist her, so they had to send someone to protect her.

This time Lan Yue is also on the list. Her mental strength is strong and she has reached C level. She is only a little behind Lin Yan. Traveling with her will be of great help.

Huahong also wanted to follow and take care of Lin Yan, but was rejected by her daughter.

There are many things at home, and I need Huahong to stay behind. It’s time to harvest chestnuts, and the second crop of june is almost ready. The green onions and leeks planted in the ground have grown.

There were too many things to do, and Lin Yan felt that Hua Hong didn't need to run around with him, so this time it was Mao Mu who took care of Lin Yan.

Huahong watched her daughter's figure getting further and further away, feeling worried that she could no longer stop her. She was extremely reluctant to leave her, but she couldn't follow her.

Ye Zi patted her shoulder and comforted: "It's okay, Lin Yan will come back safely. Last time she came back with so many people. This time she is fully equipped and accompanied by warriors who will protect her."

."

Huahong nodded silently, knowing it in her heart, but she couldn't stop thinking about it.
Chapter completed!
