The discovery of the coal mine excited people throughout the valley.

This made Su Yunnuan a little surprised. She thought that ancient people didn't know enough about coal. Looking at the excitement of these people, it was obvious that she was wrong.

Zhou Hu's face turned red with excitement, and he stood at a high place: "This is the blessed land of Cave Heaven! Think about it, everyone, it seems that whatever we need, there is it here. What is this omen? That must be when our Qi Family Army once again becomes famous in the world.

An omen, right?”

"Yes! Yes!" Many people raised their arms and shouted. The momentum was different from ordinary people. Even the children became excited.

Zhou Hu jumped down from the high platform to Lao Zhaotou, clasped his fists and said, "Village chief, please organize people to go into the mountain."

Old Zhaotou nodded: "Okay!"

Su Yunnuan finally saw the bustling scene in the valley. These people used the simplest method to carry coal back, but in just half a day it was like black coal.

How can this work!

Su Yunnuan went to the Chang Sheng brothers and asked them to make a unicycle. The unicycle was not difficult to make, but it took time. The Chang Sheng brothers specialized in making wheels with the highest technical content, and others helped make the wheels. Su Yunnuan suggested

Install box boards on the wheelbarrow so that more can be loaded and it will not fall off easily.

When Lao Zhaotou saw the wheelbarrow, he led people to build the road the next day. The chopped wood was dragged back and placed in the open space. The children who were weak used machetes to repair the thin branches, pulled out the bark, and dried it in the sun.

Dry wood is easy to store and has many uses.

Su Yunnuan came up with the idea of ​​making paper.

Just do it. Su Yunnuan asked Xiaoliu to take the children to pick off all the leaves, put the thin branches and bark together, and followed the direction of the river until she stopped where the river entered the ground.

A reservoir is dug here. Caustic soda is used in raw material processing. This becomes a natural sewage outlet and will not pollute the water source in the valley. As for where the water goes, Su Yunnuan doesn't think so.

It was something she should consider. Being able to deal with the pollutants to the greatest extent was already her limit.

After half a month, the water retention capacity of the reservoir was tested after it was dug. It was excellent. Su Yunnuan asked the people who delivered goods to Yonggu County to try and buy a lot of caustic soda. After mixing the raw materials according to the amount of water, these raw materials were mixed.

Soak in water to degumm the raw materials before proceeding to the next step.

Su Yunnuan was not idle during this period. She would only take a nap unless she was tired and anxious, and spent the rest of her time making pills.

Grandma Zhong was not idle either, leading women who knew how to do needlework to make cotton-padded clothes.

Xiaoliu collected various materials. Su Yunnuan told him that rice straw, wheat straw and various tree barks and rattan barks could be used to make paper. He firmly remembered it in his heart and led his friends like little ants every day.

Busy in the valley.

Grandma Zhong stood on the second floor of the main house, looking at the busy scene in the valley. She tilted her head and said to Su Yunnuan, "Does Nuan feel any changes?"

"Grandma, Uncle Wu is helping me. I don't know why, but he is really attractive." Su Yunnuan said.

It was as if a switch had been pressed on the people in the valley. There were no more people fishing or playing chess by the river. Everyone was doing what they could. This was a scene that had never been seen before.

Before, I tried very hard to mobilize everyone's enthusiasm, but even with the help of Old Zhaotou, the effect was not as good as now.

Grandma Zhong nodded: "Perhaps they all hope that this will become the last piece of pure land for the Qi family army."

"Yes." Su Yunnuan believes this very much. Even if she leaves the valley one day, everything here will belong to Qi Xuan, and those who belong to Qi Xuan will belong to the Qi family army. After all, those who earn wages for everyone cannot be allowed to do so.

Frozen to death in the snow.

Grandma Zhong sat down and said, "We agreed to go out once a month. It's been more than half a month now. Are you ready?"

"It's almost done. Let's send it over one after another. I don't know how Master Liao's family is preparing outside." Su Yunnuan rubbed her forehead: "I always feel like there's not enough time."

Granny Zhong patted Su Yunnuan's arm: "Don't be in a hurry, take your time. You can't eat hot tofu in a hurry."

This is the truth, but time waits for no one.

The production of sugar balls has not started yet, which means that the spies disguised as businessmen cannot leave the valley for the time being.

Let’s wait until this batch of supplies is sent away.

Su Yunnuan really felt that time was running out, but it was difficult for her to fight with two fists, and there was no one idle in the valley.

Suddenly, when the agreed time came, Su Yunnuan did not go out this time. Old Zhaotou led the team to Qingniu County. They wanted to go to Yugu Village. Su Yunnuan asked Old Zhaotou to see if the Feng Ling Army trained by Pan Yushuang

If you are qualified, if you can, escort the supplies to the front of the battle. At least it can help Liang Shiru reduce some pressure. Although Liang Shiru is also training troops, the supplies are of great importance and cannot be careless.

When you come back, bring back the sheep and piglets. Soon there will be a natural pasture here, providing a steady supply of nutrients.

And she wrote letters to her adoptive father, Qi Xuan and Pan Yuhu respectively. The adoptive father mainly talked about the sources of supplies and hoped that the adoptive father would reward them. After all, people like Liao Hong were businessmen, and they would win people's hearts by doing what they liked.

Qi Xuan's letter mentioned the prince's bloodline, which required Qi Xuan to make up his mind. Pan Yuhu's letter was more like a letter from home, telling him about the changes at home and urging him to pay attention to safety.

After sending these people away, Su Yunnuan plunged into papermaking. Xiaoliu was not big, but he was very smart. As long as Su Yunnuan came here, he would follow him every step of the way.

The retting raw materials need to be pounded to make paper pulp. The paper pulp seeps into water and becomes slurry. It is then interwoven into a thin skin-like wet paper on a paper scooper made of bamboo mats. After drying in the sun or air, it is peeled off to become paper.

The process was like this, but the actual operation was not smooth. Su Yunnuan and a dozen people were busy day and night at the edge of the valley, because papermaking cannot be separated from water sources, and the disadvantage of the warm climate in the valley is that there are many mosquitoes.

But Su Yunnuan didn't cry out in pain, and everyone was affected. They tried and made mistakes over and over again until the first piece of paper was successful, and the valley immediately echoed with the voices of children announcing the good news.

I don’t know when it started. Whenever an item is successfully developed in the valley, everyone will know about it.

Han Fengyu, who was making wine, heard the commotion and looked back with a smile on his face. It was great. Compared with the Dasheng Kingdom outside, although this valley is much smaller, the sparrow is small and has all the internal organs.

Lao Wu was making adobe bricks, and he laughed when he heard the noise. Without wiping his hands full of mud, he strode toward a yard.

"Brother Chu! Did you hear that? The eldest lady has made paper, but you still hide your ink-burning skills? Isn't that a bit unreasonable?" Old Wu spoke in a loud voice and raised his hand to open the door.

.

The door was opened from the inside, and a man in black walked out of the house: "You really have some skills. Let's go and see how good the quality of this paper is and whether it is worthy of the ink of my Chu family."

Old Wu smiled and shook off the mud on his hands: "Let's go, if you have the ability, follow this trick. The Chu family's ink is good, but I heard that Dongfang family's paper is not allowed to be used by anyone."

I’m using the Chu family’s ink.”

Chu Shicheng suddenly stopped and looked back at Old Wu with an unkind look: "Wu Ziliang!"

"Hey, you're still angry. If I were you, I wouldn't be angry. Take this opportunity to make paper that's better than Dongfang's. That's your real skill. What do you think?" Old Wu looked at Chu Shicheng with a smile.
