After Shang Qianlan returned to the room, Jiang Hao asked who was looking for her, Shang Qianlan answered truthfully what she had just done, and once again expressed her thoughts of not wanting to get married, although Jiang Hao had a sad face on his face, he didn't say anything.

At noon, the mother and daughter began to clean up and make lunch, Shang Qianlan remembered that Yu Zishi asked her to bring him when she cooked, so she made an extra one, but when it was time for lunch, Yu Zishi did not come back. Shang Qianlan took out Yu Zishi's share separately and put it in the pot, and went back to the room to eat with the family.

After a short rest, Shang Zhengqi planned to repair the Yu family's kitchen, collected some materials in the Yu family's yard, and then began to dismantle the Yu family's big stove.

Shang Qianlan was worried that she would be in a nest with Jiang Hao, and Jiang Hao would talk about Xiang Shi, so she also followed her to the courtyard and squatted in front of Shang Zhengqi's collected materials to rummage and pick them up.

Suddenly, a cracked branch caught her attention.

"What do you see?" Shang Zhengqi picked up a pile of wreckage, and when he took it out and threw it away, he saw Shang Qianlan holding a branch in a daze, and walked in to take a look, "It turns out that I looked at this, the fruit of this tree is very toxic, someone tasted it earlier, and almost lost his life." ”

Fruit is poisonous?

Shang Qianlan stood up with a look of anticipation, "Will you be nauseous and vomiting, and will you have diarrhea?" ”

"I haven't seen it, it was a long time ago, but I heard your grandfather say that eating fruit does cause vomiting and diarrhea." Shang Zhengqi was taken aback, his mouth was answering Shang Qianlan's words, but his eyes were staring at the smile on her face, how could Lan Lan seem to have heard great news?

Shang Qianlan didn't have time to think about how unusual her behavior was, and asked, "Does Daddy know where this tree is?" Can you take me to see it? ”

If her conjecture is correct, this is a business opportunity!

Shang Zhengqi took the branch from Shang Qianlan's hand and looked at it, making sure he was not mistaken, "There is a large area in the back mountain, because it is poisonous, no one in the village cuts it, but what are you doing there?" ”

"I'll talk to you slowly when I get to the place." Shang Qianlan deliberately sold Guanzi and blinked, "Let's clean up here and go up this afternoon to have a look." ”

Shang Zhengqi felt strange in his heart, but his curiosity was hung in the air by Shang Qianlan, so he simply organized the kitchen of the Yu family according to Shang Qianlan's meaning, and led Shang Qianlan to the back mountain.

As soon as she walked to the forest, Shang Qianlan's eyes were straight, that's right, these trees are tung trees!

"Dad, when it's the autumn harvest season, I have to trouble you to come up with me to pick tung seeds." Shang Qianlan roughly estimated the number of trees, and while talking to Shang Zhengqi, she walked deeper into the woods.

The tung tree is a treasure tree, in the ancient history books and medical books have recorded the wonderful use of tung oil, she has a limited memory, only know that the branches and leaves of tung oil can be used in medicine, but do not remember what the effect is, but she remembers a little, the seeds of the tung tree, tung oil seeds can squeeze oil!

Tung oil is toxic, but the oil that can be squeezed is particularly valuable, which can extend the service life of wooden furniture, not to mention the tedious processing, tung oil can also be one of the main raw materials for paint.

"Tung oil? You mean the fruit of the tree? Shang Zhengqi looked up at the treetops, now the branches of the tung tree are luxuriant, and he can see that the flower bones between the layers have not yet opened, no wonder Lan Lan said that he came to pick fruits during the autumn harvest.

Just, what does the poisonous fruit do?

"Dad used to be a carpenter, so he should know that furniture should be antiseptic, and the oil squeezed out of the tung oil can protect the furniture and make the furniture last longer." Shang Qianlan said the benefits of tung oil, and naturally finally pushed all the credit to the old man.

The person in front of her is her father, and if she doesn't find someone to blame, she will be suspicious.

"Can the oil from this thing do this?" Shang Zhengqi frowned slightly, half-believing Shang Qianlan's words.

The production of coatings for furniture anticorrosion has long been monopolized by the government, and when he used to be an apprentice in the town, the furniture sold had paint and no paint, and ordinary people could only afford to buy without paint.

If what Lan Lan said was true, wouldn't it be possible for the neighbors to use it?

"Is it useful, Dad will know when he tries it?" Shang Qianlan was very confident in her judgment, but there was still a question, "Dad, do you know who in our village can squeeze oil?" ”

The raw materials are there, she has to find tools, she can't build an oil press.

Shang Zhengqi thought for a while, "Uncle Li, who lives next to your Uncle Liu's house, is an oil extractor, and during the Chinese New Year, people in our village will go to him to extract oil or buy oil." However, tung oil seeds are poisonous, and your Uncle Li may not be willing to squeeze them. ”

That's right, everyone makes edible oil, and if they are mixed together, they will have to find her if they get into trouble.

Shang Qianlan pondered for a moment and decided to try something else first, "I'll think about this matter again, it's not summer yet, so don't worry." ”

She can't make an oil press, but she has helpers.

At night, Shang Qianlan silently recited 535 in her heart, ignored 535 when she entered the space, and went straight to the virtual screen under the tree.

"Don't even think about getting the blueprints of the oil press from here, that's not something you can make right now." 535 sensed Shang Qianlan's mood swings in the afternoon, and watched her run over, following her unhurriedly, and said quietly.

Shang Qianlan braked suddenly, can't do it?

"Old-fashioned oil presses are either cumbersome, or cumbersome, and it's a little more convenient, and it's hard for the host to find materials in this place, so according to the guidelines, the system won't give you drawings." 535 didn't wait for Shang Qianlan to ask a question, and took the initiative to explain.

"Guidelines?" Shang Qianlan furrowed her brows, "What's that?" ”

"All things exist for a certain reason or law, and if you do things beyond the scope of your own permission, you can't be accommodated by the world." 535 shook his round body, like a master in the academy shaking his head and reading.

Shang Qianlan gave it a roll of the eyes without any scruples, and said that the gods and gods chattered, both horizontally and vertically, and did not give it.

"But I'm a smart and capable elf who will definitely not let the host come in vain, so I tell the host a little secret." 535 Seeing that Shang Qianlan was dissatisfied, she became a dog's leg again, "The system can't give drawings directly, but the host can search for things related to the oil press, maybe find it again?" ”

Can she look things up here? Shang Qianlan's mood suddenly improved, and she opened the virtual screen according to 535's instructions, and found the search option on an extremely hidden page. However, when she clicked in anticipation, she was reminded that she needed to pay five achievement points.

"Yes, there is a fee." Shang Qianlan looked displeased, it's okay to collect the first point, she is only thirty points now, and five points is too high.

535 let out an embarrassed laugh and reluctantly said, "You get what you pay for, it's a little higher for the current host, but it's definitely worth the money!" Oh no! Great value for money! ”

Shang Qianlan glanced at it, but nodded with the idea of believing it.
