Zhao Shiwen didn't know what Fang ruxiu was thinking. He was still competing with Fang Yicheng and trying to pick the tea. Finally, he thought of a good way. He climbed up the tree and shook it desperately, and then the fruit fell from the ground under the tree. Hehe, he smiled at Fang Yicheng, and then picked up these mature tea on the ground.

Fang ruxiu thought this method was good, so she simply shook it in the tree by Fang Yi, the most powerful one, and picked up the tea on the ground with Fang Yicheng and Zhao Shiwen.

After shaking a tree, she tested it one by one and picked the fruits that had not been shaken down.

In this morning, she picked up all the four sacks she had brought. Fang ruxiu felt that it was a waste of time for the four people to come once, so she asked Fang Yizheng to go back to dinner with three children. She was still working here.

"Sister, I'd better stay?" Fang Yizheng said.

"It's all right, it's all right. Just bring me some rice later." Fang ruxiu said, "I like to work all at once. I don't like procrastination."

"Then I'll stay too," Fang Yizheng said.

"How about that? Yicheng and Shiwen have been busy all morning. It's time to go back and have a rest." Fang ruxiu said.

"It's all right, I'm not tired." Zhao Shiwen pursed his mouth and said, "since these days, I've been eating and drinking at my sister's house. My sister also taught me to read and write, and my aunt made me new clothes. Therefore, I feel full of energy now. It's better for me to accompany my sister on the mountain. However, how dangerous you should be as a girl."

"Your little mouth can really say that I'm from nvxia. What's the danger?" Fang ruxiu said with a smile.

"Your sister, I'll stay too." Fang Yicheng also said, "Shiwen is not tired, and I'm even less tired."

"All right, all right. Listen to me. Go back and have a rest. Come back later. Remember to bring me more sacks."

Fang ruxiu gave a final tone and asked Fang Yizheng to take these children back, while she continued to be busy.

After they all left, Fang ruxiu sat on the mountain to rest for a while, took out food from his own space to eat, and then continued to be busy.

In the afternoon, Fang Yizheng came up to deliver rice to Fang ruxiu, and the two children also came up, but everyone's efficiency was worse than that in the afternoon. After all, they were tired.

It took several days to take all the tea on the mountain back home. The sun was good these days, and Fang ruxiu dried them all in the yard.

Ye and Fang Changfu didn't know what these tea seeds were for. Fang ruxiu picked up several black tea seeds from the pile of tea seeds with shells, rolled them hard with stones, and then pointed to the yellowish liquid rolled out on the ground and said:

"Mom and Dad, what do you think this is?"

"It's sticky, like oil?" Fang Changfu was an old crop handle after all. He recognized it first.

"Yes, Dad, you're really smart. You'll get it when you guess." Fang ruxiu exclaimed.

"Well, ruxiu, what kind of tea seed oil did you specially ask these children to accompany you to pick it on the mountain for several days?" Fang Changfu seemed to have something to say and didn't agree with the tea seed oil.

"What's the matter? Is there anything wrong?" Fang ruxiu asked.

"How did you find the oil in the tea seed?" Fang Changfu asked again.

"I found it by chance when I went to the mountain at the beginning of spring this year." Fang ruxiu answered honestly.

"I thought you read it from a book and said it was called tea seed, which can be used to extract oil." Fang Changfu said with some tears and laughter: "The things you observe in life are very detailed, which is very good, but have you ever thought that when we peel oranges we usually eat, a large amount of citrus oil will splash out, but it may not be able to eat!"

Fang Changfu waved his hand and said, "this thing is like the orange peel. Although it has oil, it may not be able to eat. No one wants it. It's thanks to you taking it as a treasure."

After listening to Fang Changfu's words, Fang ruxiu was also a little embarrassed. Well, there seems to be a little truth in his father's comparison of tea oil with citrus oil, but this tea oil is really different from citrus oil, but how can I convince him? I knew I saw it occasionally from an ancient book, but now it's hard to explain.

When Fang Yizheng saw Fang ruxiu and listened to Fang Changfu's words, he kept silent, so he comforted: "sister, don't be sad. Anyway, brother is fine. It should be like going up the mountain to play for a few days. Besides, it's good to use it to burn a fire after drying."

"Yes, sister, we're both idle at home anyway. We'll do two days of work in the mountains and exercise as exercise." Fang Yicheng also comforted.

"You don't have to comfort me." Fang ruxiu said with a smile, "are you all worried that I can't think about it? Don't worry, it won't, and this tea seed can really be used to extract oil."

When they heard Fang ruxiu's words, they all looked at her curiously.

Fang ruxiu explained, "it's strange that I didn't explain it clearly to you before. In fact, this tea seed can extract oil, which I saw in an ancient book: there is a tree named Camellia oleifera, which is as low as an umbrella, with light brown and smooth bark, oval leaves and serrated edges. Its fruit has a thick shell, seeds in it, and its color is black. Its son is called tea seed, which can extract oil, and its oil color is clear and fragrant."

"That day I went to the mountain and found the Camellia oleifera. I didn't dare to believe it at first, but then I knocked it open with a stone to confirm my guess. I confirmed that this is the legendary Camellia oleifera, because I specially asked my eldest brother to pick it on the mountain together."

Fang Ru embroidered solemnly and blustered Fang Changfu. Fang Changfu said, "is this true? But if so, there were tea trees in the mountains when I was very young, and many people cut them for firewood because they were useless. If I had known earlier, it would be great."

"Yes, so I should read more books. If I didn't see this occasionally in books, I would have seen it that day and couldn't recognize it." Fang ruxiu took this opportunity to preach to Fang Yicheng.

In fact, Fang Yizheng and Fang Yicheng are already admired by each other's ruxiu. No wonder, my sister knows everything. It's because she has read a lot of books. They didn't think about how many books Fang ruxiu can read at the age of 12. They just feel that Fang ruxiu knows a lot and works hard.

After drying for a few days, most of these tea seeds burst open. Fang ruxiu had told ye that as long as the tea seeds, the outer shells of those tea seeds are used for fire or other purposes. At the right time, cultivating straw mushrooms requires these straw shells and sawdust. Fang ruxiu thinks that after the tea seed shells are rotten, they can be used to cultivate straw mushrooms.

I've been busy for several days. I've spread out a yard of tea seeds before, but the tea seeds that are really used to extract oil are not much compared with the tea seeds, but they are not less. There are four loads in total. That's four loads of tea seeds in several days. I just don't know how much oil these tea seeds can extract, but in Fang ruxiu's memory, It looks like 40% to half.

Here, four loads of tea seeds are said to be 300 kg, that is to say, at least more than 100 kg of oil can be squeezed out, which makes Fang ruxiu happier.

Oil in this era is a very precious thing. When I first came here, the Fang family fried one dish at a time, but I was only willing to take a carrot head, dip it in the oil pot, and then put a circle of oil on the pot, just dip it in the bottom of the pot.

So at that time, the dishes of the Fang family were not delicious at all. After all, the saying goes that more oil is not bad. Of course, boiled cabbage and radish without oil and water are not delicious.

"Dad, where is there a place to squeeze oil near here?" Fang ruxiu asked.

"There's one in our town. We'll just pull it by ox cart," Fang Changfu said.

"That's good. Let's pull it over tomorrow." Fang ruxiu said.

"OK." Fang Changfu nodded and agreed. He also wanted to have a look at the so-called tea seed oil. After all, ordinary peanut oil is almost fifteen Wen a kilogram, while rapeseed oil is ten Wen a kilogram. Even if the tea oil is no longer worth money, it still needs eight Wen a kilogram? If you can squeeze more than a hundred kilograms of oil here, it will be equivalent to more than a dozen silver.

Early the next morning, Fang Changfu drove the cattle to squeeze oil from the town. In ancient times, there were many oil pressing processes. First, it was fried. After frying, it was crushed. After crushing, it was steamed. After steaming, the oil powder was put into the iron ring there to make oil cakes, and then put into the chamber to start the final pressing process.

This process is all manual, so it takes a long time. It was not until the evening that Fang Changfu came back from town with an ox cart.

Fang ruxiu was the first to greet him and said, "Dad, why did you come back so late? Even those who went to school in Yizhi came back soon."

"Our family used a lot of tea seeds to crush this time, so it took a long time," Fang Changfu said.

"Oh, did the master of the oil mill say anything?" Fang ruxiu asked again.

"I asked a question or two, but they didn't take it to heart." Fang Changfu said, "many people in this place take some strange things to extract oil. Many people even pick the small tea seeds on the tea tree to extract oil."

"Oh." Fang ruxiu nodded, and then helped Fang Changfu unload the tea oil and tea cakes from the ox cart.

This tea oil is filled with five large iron barrels in that small iron barrel, and there is another half a barrel. Fang Changfu said that each barrel can hold 30 kilograms of oil, that is to say, more than 160 kilograms of oil were squeezed out of the more than 300 kilograms of tea seeds.
