It's the day of the market again, after Xi Baolin went to work in the toothbrush workshop, Xi Yuexin was alone in selling tooth powder on the market day, and before going to Huangshui Town, Xi Yuexin specially discussed with Xi Baolin about squeezing tea seed oil.

"You've decided to cooperate with Shopkeeper Song?" After listening to Xi Yuexin's plan, Xi Baolin asked again.

"Well, Dad, I've already thought about it, our family has no power and powerless, once tea seed oil becomes a must-use oil for every household, I'm worried that our family will not be able to keep this oil extraction technology, although I don't know what the origin of the owner of the Song shopkeeper is, but since his owner can open branches all over Zewen Country, it means that his owner is not weak, and the only powerful person we know is the Song shopkeeper." Xi Yue said with a heavy heart.

"Well, what you say makes sense, just do what you say." Xi Baolin pondered for a while and then nodded in agreement.

"Okay, I'll go to Shopkeeper Song after selling the tooth powder, and then I can read a few words with him by the way." After Shopkeeper Song promised to teach her to read, every time she sold out of tooth powder on a market day, Xi Yuexin would go to Fengsheng Grocery Store to find Shopkeeper Song to read.

"Go ahead." Her daughter is so diligent and studious, Xi Baolin is very pleased.

In Huangshui Town, Xi Yuexin sold a hundred packs of tooth powder, put away the black cloth used to set up the stall, and went directly into the Fengsheng grocery store.

In the study, Shopkeeper Song was reconciling the account, Xi Yuexin didn't bother him, found a chair to sit down, and waited quietly.

After Shopkeeper Song finished checking the account, he found that there was an extra person in the study, so he asked with a smile, "When did Yuexin come?" Why don't you make a sound? Waited, right? ”

"As soon as I arrived, I sat down, and the shopkeeper Song was busy." Xi Yuexin replied with a smile.

"Okay, let's learn a thousand words today." Listening to Xi Yuexin's thoughtful words, Shopkeeper Song smiled happily, stood up as he spoke, walked to the bookcase, pulled out a book and handed it to Xi Yuexin.

When Xi Yuexin stepped forward to take it, she also said her intention today: "Shopkeeper Song, I still want to discuss something with you when I come today." ”

"Oh? What's the matter? Hearing that Xi Yuexin had something to talk to him, Shopkeeper Song was immediately interested.

"It's the mountain land that my family bought." Xi Yue replied calmly.

"Thinking of a plan to make a fortune?" Hearing Xi Yuexin mention the mountains, Shopkeeper Song's eyes lit up and asked.

"Actually, what my dad and I really wanted to buy was not mountains, but trees." Xi Yuexin explained.

"Trees?" Shopkeeper Song was puzzled.

"Well, this kind of tree is called the tea oil fruit tree, and the fruit it produces can be used to extract oil, and the oil can be used for stir-frying." Xi Yuexin explained in as concise words as possible.

"Can the fruit be squeezed for oil?" Shopkeeper Song thought it was a novelty, he had lived for decades, and for the first time he had heard that the fruit of trees could be squeezed for oil.

"Yes, this oil is called tea seed oil, which is a type of vegetable oil." Xi Yuexin nodded and said.

"What is vegetable oil?" Shopkeeper Song frowned and asked, why are there so many novel words in this pleasant heart?

"Let's put it this way, now we don't use fat lard to squeeze out of vegetable frying, called animal oil, trees, vegetables, weeds, all belong to plants, and the fruit squeezed from them is not called vegetable oil." Xi Yuexin patiently explained.

"Oh, that's the way it is, everything that moves is called an animal, and what is planted in the field or grows in the mountains is called a plant." Shopkeeper Song nodded quietly and said.
