When repairing the "bicycle", Wang Dong also knew that it was not called a bicycle, but a waste of grain collectors.

Because in that world, food is scarce, and it is very expensive. However, a grain of grain is very small, whether it is harvested or dried, it is inevitable that the phenomenon of scattering will occur.

Wang Dong remembers that when he was a child, when there was no harvester, he used to harvest by hand and with a sickle.

Harvest is often started when the wheat is still green, but when the harvest is finished, the wheat is yellow, dry, and with a little force, the wheat grains will fall down. And now, with the combine harvester, there is still this phenomenon, sometimes even more than before, and it is even more scattered.

If the harvester is serious, there will be less scattering, and if the harvester is so-so, then sorry, the wheat must be everywhere.

Maybe some people didn't care at the time and couldn't see it, but when it came time to plant corn, many wheat grains sprouted, and they were often in large patches, large patches.

Wang Dong once estimated that one acre of land would cost about two catties of wheat. Some people may think that these two catties of wheat are nothing, and if they are exchanged for steamed buns, there are only a few, and even if they are sold, they are only more than two yuan.

But this is only one acre of land, if it is ten acres of land, a hundred acres of land, a thousand acres of land, ten thousand acres of land...... In that case, it would be a considerable amount of food.

"Wow, that's so much"? Thinking of this, Wang Dong checked the Internet to see how much arable land there was in the city. However, after an investigation, it was found that there were 3.5 million acres of cultivated land, and even if only 3 million mu was planted with grain, according to two catties per acre of land, it would be 6 million catties.

It's just a city, and if it's a province, how much is it? So much, how many people can be saved?

Wang Dong lamented that although the country is rich in land and resources, and it is also a big grain country, it is only a balance of payments, and even some, such as soybeans, will be imported in large quantities.

In the east, fine, in the remote mountainous areas of the west, food is still scarce.

"It must be repaired, no matter how much gold is needed." Wang Dong swears that this machine is really too useful, not only for himself, but also for many people in need.

"Otherwise, let's build a factory." Wang Dong estimates that the grain will be piled up at that time. However, it is better to sell grain than to process it deeply, in that case, the value will be higher, and the profit will be greater.

Since it is a business without capital, Wang Dong plans to donate most of the profits to report to the society when the time comes.

"Hey, let's think about it." Wang Dong was depressed, it would take millions of gold coins to repair the machine, but he was only about 100,000 gold coins when he was full, and he was still short of nearly 900,000 gold coins.

"Or, devour real-world garbage"? Now there is a lot of garbage in the society, more second-hand goods, waste cars, mobile phones, stainless steel doors and windows...... The whole nine yards.

But Wang Dong calculated, these things, when recycled, are not expensive. If you want to save 900,000, you have to be a mountain of second-hand goods about a kilometer high.

"Forget it, let's choose the more expensive one." The more expensive ones are nothing more than gold, silver, jewelry, jade, and jade.

"By the way, let's use jade jade." Wang Dong suddenly thought that he had seen a master of jade carving before, carving a piece of fine Hetian jade into jade pendants, earrings and the like, but in this process, it is inevitable that there will be leftovers.

And these leftovers are all a small piece, a small piece, the root is not enough to carve anything, so the value is very low.

In order to test whether this was the case, Wang Dong decided to test it. So Wang Dong drove to the town, and then spent 200 yuan to buy two identical jade pendants. When he got home, Wang Dong picked up a hammer and smashed one of the jade pendants into several petals.

"If that's the case, then it's easy to do." Wang Dong was very happy, the result was really the same as he expected. The value of the gold coin that was thrown into the jade pendant and the value of the gold coin of the smashed jade pendant were very similar, and the difference was very small.

There are so many jadeite and jade carvings every year, and there are a lot of leftovers over there. Wang Dong thought about it and decided to go to the capital and take action. After all, in the sea of clouds, there is not much jade processing, and if you want leftovers, even if you have them, there will not be a lot.

But the capital is different, Wang Dong believes that not only the leftovers of 900,000 gold coins, but also 9 million, can also be collected.

"Dongzi, Weiwei has been gone for more than ten days, I'm always uneasy in my heart, otherwise, you can go and see it again, Weiwei's girl, she has never been far away, and I don't know if she will take care of herself." Liu Xia and other places were all busy, so they pulled Wang Dong and said.

"Well, okay, Mom, I'll go tomorrow." Wang Dong originally wanted to go to the capital and ask Su Yu if he was interested in selling rouge rice.

Moreover, Wang Dong also misses his little sister a little. Thinking of Wang Wei's personality and the personality of his roommate, Wang Dong decided that Wang Wei would not have any problems.

"Well, this capital, but it's farther north than we are here, I heard that in winter, it's much colder than ours here, I washed a few thick clothes yesterday, you can bring them over tomorrow." Liu Xia misses her daughter a lot, but she can't do the train herself, so she has to let Wang Dong go to see it often.

"Okay, I got it, I'm all set". Wang Dong was also speechless, and last night, he called Wang Wei and said that he would go to the capital in the next few days.

"Big brother, bring me some tomatoes, fruits from our orchard, fish from our pond, and spicy chicken, and" ......

Wang Wei actually asked for food.

"You little gluttonous cat, you know how to eat". Wang Dong scolded with a smile, but still, prepared a lot of food for Wang Wei.

"Nana, do you have time, let's go to the capital for a few days." Because it was a weekend, Li Na stayed at home and didn't go to class.

"Go to the capital, but, I don't have time, tomorrow my mother said, let me go home, I hate it." Li Na said with annoyance that she usually didn't see her mother summoning her, but this time, Wang Dong wanted to take her to the capital and was going home.

"That's okay, anyway, in the future, there will be opportunities." Wang Dong originally thought to himself that tomorrow would be Saturday, and there would be no classes on Saturday and Sunday. Li Na didn't have to go to work, she was invited by Wang Dongcai. But now, I have no choice but to give up.

Wang Dong brought not many things this time, most of them were food, and the rest were some of Wang Wei's clothes.

Of course, Wang Dong still brought ten catties of rouge rice, facts speak louder than words, only when he sees the real thing, can Su Yu have a rational judgment.

Because this time, in a hurry, it was decided by Wang Dong that it would be better to take the high-speed rail. Because the family is close to the sea and the mountains, it is corn, which ripens relatively early.

Elsewhere, it should have just begun, and in some places, it will take a few days. Wang Dong decided that the best thing would be to be able to repair the machine before the autumn harvest.

Otherwise, what is the use of waiting until autumn and winter, when the grain has sprouted, and then collecting it back?

"Phew, I'm back again". It was only about four hours before Wang Dong came to the capital.

"It's here, it's here, it's you're in a hurry"? Wang Dong had just gotten out of the car, and Wang Wei's call arrived, and including the call from the car, it was the fifth.

"It's here, where are you, the train station, it's still our school, I'll go get it for you." Wang Wei was very happy that the eldest brother could come, compared to the junk food at school, Wang Wei had been looking forward to the meals and fruits at home for a long time.

"It's still at the train station, half an hour to you." Wang Dong said angrily, ten minutes ago, he was still on the train, how could he get to the school gate! (To be continued.) Mobile phone users, please browse and read, a better reading experience.
