Now that Lan Yue is here, of course the three of them can't let her go and ask about what they saw on the road.
Mentioning what happened along the way, Lan Yue's eyes sparkled with inexplicable light.
Lin Yan couldn't believe it when he saw it, "What treasure did you find again?"
Thinking of Lan Yue's good luck, her eyes turned red with envy. It's a pity that I couldn't accompany him to the mines these two times, so I didn't get any glory.
She must go next time. The wheat has been planted and the important matter in her heart has been settled. Lin Yan feels that it is enough to leave this matter to others to continue to watch.
Lan Yue smiled gently and dug through the linen bag she was carrying behind her back. She took out a notebook and opened it to one of the pages. Pointing, "They're all here."
Shi Zhi grabbed the book and took a quick look at it. He wrote a full page. When he took a closer look, one of the items contained three roots of wild ginseng, and below was 3 pounds of seven-star lotus...
"Did you find all of this?"
Lan Yue nodded reservedly, "Yes, there are treasures everywhere outside. Of course you should bring them back if you encounter them."
Lin Yan couldn't bear it anymore, grabbed the notebook from Shi Zhi's hand, and read it carefully. The more I looked at him, the more jealous I became. God was indeed unfair. His preference was too obvious.
Lin Yan fixed his eyes on one of the lines and asked carefully, "What is this?"
Lan Yue looked closely at her finger, "I found it in the mine. I don't recognize it. It's like a kind of wild fruit. One is as big as the mouth of a bowl. The fruit is round. It grows on tall trees. I picked it. I brought two back."
"Where is the thing? Let me take a look." Lin Yan asked hurriedly. The fruit of an unknown tree might be useful.
"Let Lan Xing take it home. Let's go take a look."
Lin Yan nodded. He knew everything else. They were basically herbs, with many types and quantities.
Shi Zhi and Ye Cong were also curious, and they went to Lan Yue's house together.
When he saw the wrinkled fruit, Ye Cong said in disappointment: "It looks like it's wrinkled into a ball, so you can't eat it."
Shi Zhi sounded regretful, "It doesn't look good, it doesn't look like an edible wild fruit."
Lan Yue ignored them and stared at Lin Yan.
Lan Yue breathed a sigh of relief when she saw Lin Yan taking the thing in his hand. After a while, his facial expression soothed.
"It's true that it can't be eaten." Lin Yan said, putting the things down, ready to open them and look inside, and asked Lan Yue to find a knife.
"Since you can't eat it, what are you looking at?" Ye Cong was puzzled.
Lin Yan said: "It can't be eaten, but it can be used. I looked at the seeds inside. It should be a treasure and can be used in many places."
Shi Zhi became interested, "What is it and where is it used?"
"This is the tung oil fruit, the fruit of the tung tree. Peel off the shell and the seeds inside are good and can be used to extract oil."
"It's not much use to extract oil. We have too much hemp oil to eat." The oil shop run by Ye Cong's family has a good business, and they all make some hard money by extracting oil for others.
Since the oil shop opened, less than ten kilograms of hemp oil have been sold. Ye Cong is very dissatisfied with things that extract oil.
"I told you it's not for eating." Lin Yan emphasized, "What is squeezed out is tung oil, a kind of industrial oil. It cannot be eaten."
"Tung oil is a kind of dry vegetable oil. It has the characteristics of fast drying, light specific gravity, good gloss, strong adhesion, heat resistance, acid resistance, alkali resistance, anti-corrosion, anti-rust, non-conductivity and other properties. It has a wide range of uses. It is used for manufacturing paints, The main raw material of ink is widely used as waterproof, anti-corrosion and anti-rust coatings in construction, machinery, weapons, vehicles and boats, fishing gear, and electrical appliances. It can also be used to make oilcloth, oil paper, soap, pesticides, medicines, insecticides, etc.”
Ye Cong was dumbfounded, "So many uses?"
"Of course. With it, the wooden furniture we usually use can be coated with a layer of insect repellent, bright in color, and last longer."
Shi Zhi's eyes lit up, "What a good thing. We need to collect more tung oil fruits and let's press the oil for experiments."
Lan Yue came back from looking for the knife. When she saw their appearance, she quickly asked, "What is this?" When she left, they both looked regretful, but now their faces were filled with excitement. It must be something good.
Ye Cong repeated what Lin Yan just said, word for word.
Finally, he asked: "Are there many tung oil fruits?"
Lan Yue nodded, "In the mountains to the north from the mine, there are a large number of tung trees. They grow very tall, more than ten meters high, and bear a lot of fruits."
"Okay, when we go to the mine again, we must pick more tung oil fruits and come back." Ye Cong couldn't wait, he wanted to try the effect of tung oil.
Shi Zhi is also looking forward to it. There are so many uses for tung oil waiting for them to develop, so this matter cannot be delayed.
Lin Yan took the tung oil fruit and cut it open. The seeds inside were very full. She nodded with satisfaction: "Very good. Such a big tung oil fruit has more than half a catty of seeds. It is worth picking."
"When are you going to pick them?" Ye Cong wished he could go now. He was most curious about these novel things.
The tarpaulin and waterproof materials mentioned by Lin Yan just now also aroused Shi Zhi's interest. He asked Lan Yue: "Is the road to the mine determined?"
Lan Yue nodded, "The route has been determined. It took us a long time to go back and forth this time, just to clear all the difficult sections. After walking a few more times, the road will be clear. When we come back this time, we will see the ground The roads there have been built, so does the road to the mine have to be built like that?"
"Of course it needs to be repaired." Ye Cong said first, "You haven't seen a truck before. The road needs to be built wider so that the truck can pass. From now on, the truck will have to be used to haul ore. It won't work if the road is not repaired."
"Is the frame truck ready?" Lan Yue looked at them in surprise. Before leaving, she knew that they were busy making the frame truck, but she hadn't seen the real thing yet.
Lin Yan said with a smile: "It's done. This year's harvest of june and wheat will be done with a frame truck, and it has been proven that it works. One person can pull hundreds of kilograms of things. When this year's wheat harvest is completed, every family will not be short of food. After that, we started building the road.”
It was getting late. Seeing that Lan Yue was tired, several people left first.
On the way home, Ye Cong said excitedly: "When will the road be repaired? I also want to go to the mine."
Shi Zhi didn't leave either and was equally in high spirits.
Lin Yan said: "When the road is repaired, you all can go." But in his heart, he was thinking that it would take at least a year or two. By then they would have grown up and it would be time for them to go out and gain experience.
The mining team returned safely, and Sun City was very lively that day.
Every household is celebrating. Every time the mining team comes back, they bring back more ore and all the tools they need.
Nowadays, not every household has an iron pot or kitchen knife. Ironware is in short supply and the price is high. With more ore, the price will naturally come down.
As long as there is enough ore, you can make any tool you want. What more people want to have are sharp weapons.
Many people have realized that in the future they will not stay in the Sun City. Going out is inevitable, and they must prepare early.
During the family dinner in the evening, Lin Yan mentioned the tung oil fruit brought back by Lan Yue, and Hua Hong also excitedly said that the mining team had brought back more than two thousand kilograms of ore.
That night, most families were like Lin Yan's family, discussing the ore brought back by the mining team, hoping to buy the iron tools they wanted.
