Since Lan Yue came, of course the three of them couldn't let her go, and asked about what they had seen on the road.

Speaking of what happened along the way, Lan Yue's eyes flashed with inexplicable brilliance.

Lin Yan looked at it and was incredulous, "What treasure did you find again?" ”

Thinking of Blue Moon's good luck, her eyes were red with envy. It's a pity that these two trips to the mine failed to accompany them, and they didn't get stained.

Next time she must go, the wheat has been planted, but the big thing in her heart is, Lin Yan feels that this matter can be left to others to continue to watch.

Lan Yue smiled gently, and pulled out the burlap bag she was carrying behind her, only to see that she took out a notebook and opened it to one of the pages. He pointed and said, "It's all here." ”

Shi Zhi snatched the notebook, took a cursory look at the full page, and took a closer look at one of the three wild ginsengs, and below was 3 catties of Seven Star Lotus......

"You found all this?"

Lan Yue nodded reservedly, "Yes, there are treasures everywhere outside, of course you have to bring them back when you encounter them." ”

Lin Yan couldn't bear it, snatched the book from Shi Zhi's hand, and read it carefully. The more I look at it, the more jealous I become, God is really unfair, and the preference is too obvious.

His gaze was fixed on one of the lines, and Lin Yan asked carefully, "What is this?" ”

Blue Moon leaned closer to look at her finger, "Found in the mine, I don't know it." It was like a wild fruit, one the size of a bowl, the fruit was round, and it grew on tall trees, and I picked two of them and brought them back. ”

"I'll see where the stuff is." Lin Yan hurriedly asked, the fruit of a tree that he didn't know might be usable.

"Let the blue star take it home. Let's take a look. ”

Lin Yan nodded, everything else is known, basically all herbs, there are many types, and there are quite a few of them.

Shi Zhi and Ye Cong were also curious, and they went to Lanyue's house together.

When he saw the crumpled fruit, Ye Cong said disappointedly: "I look at the crumpled ball, I can't eat it." ”

Shi Zhi's tone was regretful, "It's not good-looking, it's not like a wild fruit that can be eaten." ”

Lan Yue ignored them and stared at Lin Yan.

Seeing Lin Yan take the things in his hand, after a while, his facial expression was soothing, and Lan Yue breathed a sigh of relief.

"It's true that you can't eat it." Lin Yan said, putting the things down, preparing to open them to take a look inside, and let Lan Yue find a knife over.

"Since you can't eat it, what else are you looking at?" Ye Cong was puzzled.

Lin Yan said: "You can't eat it, but you can use it." I look at the seeds inside, it should be a treasure, and it can be used in many places. ”

Shi Zhi became interested, "What is it, and where is it used?" ”

"This is the tung apode, the fruit of the tung tree. Peel off the husk, the seeds inside are good things to be able to squeeze oil. ”

"It's useless to squeeze oil, we can't eat enough hemp seed oil." The oil mill opened by Ye Cong's family has a good business, all of which are to squeeze oil for people to earn some hard-earned money.

Since the opening of the oil mill, less than ten catties of hemp seed oil have been sold. Ye Cong is very optimistic about oil extraction.

"It's all said it's not food." Lin Yan emphasized, "What is squeezed out is tung oil, an industrial oil, which cannot be eaten." ”

"Tung oil is a dry vegetable oil, which has the characteristics of fast drying, light specific gravity, good gloss, strong adhesion, heat resistance, acid resistance, alkali resistance, anti-corrosion, anti-rust, non-conductive, etc., and has a wide range of uses. It is the main raw material for the manufacture of paints and inks, and is widely used as waterproof, anti-corrosion and anti-rust coatings for construction, machinery, weapons, vehicles and ships, fishing gear and electrical appliances, and can be used to make oilcloth, oiled paper, soap, pesticides and medicines, insecticides, etc. ”

Ye Cong was dumbfounded, "So many uses? ”

"Of course. With it, the wooden furniture we usually use is coated with a coat, which can prevent insects, the color is bright, and it lasts longer. ”

Shi Zhi's eyes lit up, "Good thing." If we want to pick more tung oil fruits, we will squeeze the oil for experiments. ”

Lan Yue came back from looking for knives, saw their appearance, and hurriedly asked, "What is this?" "When she left, the two of them looked regretful, but now their faces are excited, it must be a good thing.

Ye Cong repeated what Lin Yan had just said, word for word.

At the end, he asked, "Are there many tung pewberries?" ”

Lan Yue nodded, "In the mountains to the north of the mine, there is a large area of tung trees, which grow very tall, more than ten meters high, and bear many fruits. ”

"Okay, when I go to the mine again, I 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 of tung oil waiting for them to develop, and this matter cannot be delayed.

Lin Yan took it and cut the tung oil fruit, the seeds inside were very full, she nodded with satisfaction: "Very good, such a big tung oil fruit, the seeds are more than half a catty, and they are worth picking." ”

"When are you going to pick it?" Ye Cong hated to go now, he was most curious about these novelties.

The tarpaulin and waterproof material mentioned by Lin Yan just now also aroused Shi Zhi's interest, and he asked Lan Yue, "Is the road to the mine confirmed?" ”

Lan Yue nodded, "The route has been decided, we have come and gone this time, and it takes a long time on the road, that is, we have cleaned up all the difficult sections." After a few more walks, the road will come out. When I came back this time, I saw that the roads in the fields had been repaired, and the roads to the mines should be built like that? ”

"Of course it has to be repaired." Ye Cong preemptively said, "You haven't seen a frame car yet." The road should be built wider so that the rack car can pass. In the future, it will be necessary to rely on rack trucks to pull ore. If the road is not repaired, it will not work. ”

"Is the rack car ready?" Blue Moon looked at them in amazement, knowing that they were busy making a frame car before leaving, but they hadn't seen the real thing yet.

Lin Yan said with a smile: "It's done, this year's harvest of thorn and wheat is pulled by a rack cart, and it has been confirmed that it can indeed be used." One person can pull hundreds of pounds of things. When this year's wheat harvest was complete and the family was not short of food, they began to build roads. ”

It was late, and a few people saw that Blue Moon was tired and 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 never left, and he was also in high spirits.

Lin Yan said: "When the road is repaired, you all go." But I was thinking in my heart that I would have to wait at least a year or two, and then they would all grow up, and they should go out to learn more.

The mining team came back safely, and it was very lively in Sun City on this day.

Every family is celebrating, and 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 kitchen knife, iron is tight, the price is also high, and with more ore, the price will naturally drop.

As long as there is enough ore, you can make whatever tools you want, and more people want to have sharp weapons.

Many people have realized that they will not shrink in Sun City in the future, and it is inevitable to go out, and they must prepare early.

At dinner as a family in the evening, Lin Yan mentioned the tung avocado brought back by Blue Moon, and Hua Hong also said excitedly that the mining team brought back more than 2,000 catties of ore.

This night, most of the families were like Lin Yan's family, discussing the ore brought back by the mining team, hoping to buy the iron tools they wanted.
