The people in Changzhen Village are more literate than those in Changjiang Village. There are at least two or three students who can read and write in the village. Tong Wenyao wrote down the method of composting on a piece of paper and handed it to him.

Zhang Fu took it carefully, then folded it on the bag before saying goodbye to her.

Tong Wenyao wasn't sure if she could compost the land in time for spring planting, as it would have to be spread on the fields. Seeing the two little ones staying with her in the villa, playing with their toys instead of taking in the scenery, she took them to where they had composted the land. Uncle Du followed behind and said, "There's a war on the border. This piece of land originally belonged to Landlord Hu, but he was worried about an attack, so he sold it, packed his bags, and is now heading south!"

Tong Wenyao looked at a large area of ​​land with several hillocks protruding from it and asked, "Are all these being used to make compost?"

Uncle Du nodded and said, "It's been about ten days. Tomorrow I'll have someone tear down the hillocks and spread the fertilizer on the ground. Landlord Hu had someone tidy up this piece of land earlier, so now we just need to spread the fertilizer."

Tong Wenyao nodded and said, "Use a shovel and an eight-foot rake to do it. It's best to cover your mouth and nose with a cloth, otherwise the smell will choke you."

Uncle Du nodded and said, "Okay." Tong Wen Yao thought about it and decided to let them get a cloth mask so that they don't have to tie it.

She will draw the shape of the mask when she gets back, and then she can ask Aunt Shu and Ping'an to embroider it.

Uncle Du was looking for someone to spread the fermented fertilizer on the fields. The pungent smell blew towards them with the wind. Tong Wen Yao frowned. The smell was not very pleasant, but it could ensure a good harvest, so she could endure it for a while.

She said, "Uncle Du, you can pay more for the workers you hired. This smells bad. Thank you for your hard work."

After hearing this, he said, "Don't worry, young master! I have arranged everything."

The winter melons that Tong Wen Yao brought from Cangzhou last time can be planted after the Dragon Raising Day next month. As for the Hami melons, they can be planted half a month later. Just make sure that the melon seedlings will not be frozen.

However, she guessed that the weather would not get colder at this time, but to be conservative, Tong Wen Yao still asked Uncle Du to start planting next month, but she might have gone to the south by then.

That night, Min Zhi also came back. When he heard that the boss was there, he immediately ran over.

"Boss! You're back." Tong Wenyao asked him to sit down and asked, "How's the construction of the cement building going?" Min Zhi scratched his head and said a little embarrassedly, "Boss, we just laid the foundation. I estimate it will take another seven or eight days to complete."

"Thank you for your hard work, running back and forth every day. When the house over there in the cement building is built, you can live there too." Min Zhi smiled and said, "Boss, it's close to home, and if I don't come back, who will look after me?"

Tong Wenyao didn't dwell on it after hearing this and said, "It's up to you."

Thinking of the two people that Zhang had sent today, she said, "Some people will go to the cement building to learn in a few days. You can find someone to teach them then." Min Zhi said, "Boss, what will we do if they steal our business in the county?"

Tong Wenyao explained, "After this team learns, they will go to the capital to build houses. Manager Zhang has also promised me that they will not do it in Yuguan County. However, if you expand your scope, we will control the production materials and they will have to buy from us."

After hearing this, Min Zhi didn't dare to say anything, but he believed in the boss's judgment.

I will figure out the method of making glass in the next few days. When the time comes, the county magistrate will come to see it. As we agreed before, he will give me 20% of the profits. If I am not here, you can ask Uncle Du to accompany the county magistrate. I will study how to make glass in the next few days.

Min Zhi didn't know what glass was, but since the boss said so, then this was a way to make money.

Seeing his puzzled expression, Tong Wenyao patiently explained, "It's a transparent thing. It can be installed on the window. In this way, sunlight can shine into the room through the glass, and there will be no need to light candles in the room.

After learning about it, Min Zhi became even more curious. If it wasn't dark outside, he would have probably dragged his eldest brother out to make glass.

"Boss, will it get wet if it rains, and then break?" Tong Wenyao said with a smile, "Rainwater won't break it. It's mainly if you hit it with a sharp object that it will break."

Xin'er said, "This is much better than window paper. Window paper will be damaged if burned by fire, but glass is not afraid of fire."

Tong Wen Yao touched Xin'er's head, "You clever ghost!" Xin'er made a face at her, and then went to play with Wen Jiang. Tong Wen Yao placed a lot of toys in the villa here, so Wen Jiang and Xin'er were reluctant to go out all day. If she hadn't dragged them out to see the composting in the afternoon, they would not have wanted to go out!

Seeing that it was getting late, Tong Wen Yao said, "Min Zhi, if you don't go back to sleep, will you be able to get up the next day?" After finally driving Min Zhi away, Tong Wen Yao went upstairs to take a bath and slept comfortably.

The bed here is relatively soft, made of fine wool. Tong Wen Yao rolled around twice comfortably on the bed.

Early the next morning, Tong Wen Yao took Xing'er to the back mountain with the method of making colored glass in her hands. A place dedicated to making glass had been opened up in the back mountain, and sand was piled on the side.

She called Guan You and said, "Guan You, put sand and limestone into the crucible in a ratio of three to one, and continue to burn the fire. The temperature should be about the same as that of burning lime. When the material in the crucible becomes a mass like liquid, put it into the mold." The mold was made of the material used to make crucibles, and its size and shape were about the same as those of modern windows.

Tong Wen Yao had previously thought of using iron to make a mold, but the temperature was too high and it would melt. The crucible happened to be able to withstand it, so she simply used the material used to make the crucible to make a container for the glass of water.

However, it may take more than two or three days to complete the firing.

Tong Wen Yao originally planned to stay here, but considering that Xin'er and Wen Jiang were in the villa, she returned to accompany them. She would bring them to the back mountain the next afternoon and ask Xing'er to keep an eye on them. She would come here to see if the glassmaking was completed and whether there were any mistakes that would cause the firing to fail.

At the same time, the barbarians launched another attack on Dongsai City. This time, Tong Hong led his men to fight to the death and beat the barbarians back again. Dongsai City also suffered heavy losses. From the original 40,000 troops, 15,000 troops were lost. Now, Dongsai City only has 25,000 troops.
