He plans to make use of the ten acres of yellow sand land at the top of their village, where to plant gastrodia, although this thing is also wild, but the output value cannot be guaranteed, so as long as he can mass-produce, this thing will definitely be popular in the Lingnan area.

And he can use hemp oak trees to grow fungus, but if these things want to get rich, they will have to wait at least a year or two later, and what Jiang Wei needs most now is time, so he plans to go to Chang'an.

Thinking carefully about the topography of Shangwan Village, Jiang Wei took out a quill and began to draw sketches on the paper, from noon to afternoon, when the sun was in the west, Jiang Wei was busy with the things in his hand.

As soon as I rolled up those drawings, I saw my grandmother coming over with a porcelain bowl, Jiang Wei hurriedly got up and took it in her hand and said, "Grandma, why are you serving things again?" ”

"This is your lunch, your father and mother have left long ago when they come back to eat, this is for you. I'll give you a hot one, so let's eat it. Xing'er, I'll tell you that grandma is not very old, don't listen to your father's nonsense, I don't have any problems repairing the canal. On weekdays, your father and mother won't let me go to the ground, so now I should be allowed to go to the canal, right? ”

Jiang Wei smiled and said, "Grandma, isn't it good for you to go out and walk around, chat with those old people in the village, and bask in the sun?" Why do you keep thinking about work? We are all repairing the ditch like this, and there is no one to take care of at home, so I will find you a good job, and in two days I will build up the wall of our yard, catch a few chickens, and catch two pigs back, and then you will be responsible for feeding them and helping us cook by the way, what do you think? ”

"You kid, that pig is a foodie, what are you raising it for? And we can't afford that chicken. People have nothing to eat, where can they get anything to feed the chickens? ”

Jiang Wei was noncommittal about his grandmother's words, these days people can't raise chickens and pigs, and there are even fewer of them, pork is something that only untouchables will eat, and ordinary people naturally disdain it, but Jiang Wei let pigs not be raised for food.

In this era of low productivity, the best thing about raising pigs is actually to step on manure, for some craftsmen, wheat straw is used to make clothes, straw hats of raw materials, but for ordinary people in addition to blocking the roof to increase the temperature of the bed, the only thing left is to make a fire for cooking.

But if you let the pig step on the manure is different, the excess straw can be used as fertilizer, now we have not used the habit of using farm fertilizer, even if there is no fixed place to go to the toilet, the only way people can think of is to get some silt from the river or water to increase the yield of grain, as for farm fertilizer does not seem to have this concept.

In this cow can not be eaten. Pigs are lowly things, only chickens, ducks, fish and sheep are considered to be the things that are eaten by superior people, chickens are completely a burden for the poor, it is good to lay eggs, if you don't lay eggs, then the problem is big, and what you eat every day can make people have a toothache.

Jiang Wei didn't argue with his grandmother, whether it was before or later, one of his ways to deal with the old man is that I can listen to what you said, but I will never copy it, selectively forget, just don't contradict them, as for some things, although adults are thoughtful, they are not suitable for young people to do.

After eating the things in the bowl, Jiang Wei was half full, but he didn't say anything, but took the drawings of the things on the table, said to his grandmother, and hurried out of the door and rushed towards the river.

If you want to say that there are still many people and great strength, it is impossible to build this dam in seventeen or eighteen days, but after these young people from Shangwan joined, it was completely different.

Because of Jiang Wei, they didn't complain about the lack of people in Bayuan, but they worked hard to repair the dam as soon as possible and then build their canals, so these people worked extremely hard. After more than half a day's work, a group of forty or fifty people was stunned to empty the large stones that could be moved around the embankment. An experienced river worker stood on a makeshift wooden frame and instructed the young men to put the boulders into the river and set them up with the previous stones.

To say that Jiang Wei's father is an expert in these things, but Jiang Wei is completely a layman, seeing everyone's enthusiasm, Jiang Wei shouted at the right time: "Folks, do a good job, and when you are done with this while, I will teach you a good way to increase the yield per mu by at least one-third." Plant our inferior fields with the yield of their superior fields. ”

"Jiang Wei, if you want to say that you are an expert in this brain, but your father is much more reliable than you in this kind of crop, otherwise he will not be able to support your two brothers, we would rather believe him than believe you."

An uncle who knew each other began to make fun of Jiang Wei, Jiang Wei laughed and said: "It is said that the back wave pushes the front wave, and one wave is stronger than the other, if you don't believe it, just wait and see." Jiang Wei didn't say anything, and rushed towards Shanwan Village with those river maps.

The dam looked to be completed in a day or two, and Patriarch Liu was looking forward to Jiang Wei's river map. Now when he saw Jiang Wei coming, he hurriedly greeted him and said, "Nephew Jiang Xian, how do you think the situation in our village should be handled?" ”

"I suggest digging a canal along the side of the loess layer of Jieshan Mountain, circling the mountain, just enough to let the water flow through the top of your mountain field, and build a canal at intervals to the bottom of the mountain, the canal is dug higher than the water level, and let the water in the canal circle around the mountain on weekdays and then return to the Bahe River, if you use a wooden board or stone to block the canal during irrigation, raise the water level and let the water level cross the river, you can complete the irrigation."

"It's all very simple, where to start, how high the terrain, how to connect, it's a question."

"I've already drawn a map of the river in the general direction, are you ready for landmarks, hammers, red paint, etc.?"

Patriarch Liu nodded and said, "It's ready." “

"Well, now that you're ready to bring a dozen young men with good labor, take your things and follow me up the mountain."

"No problem"

"Here, cut down the mountain, build it with stones on the outside, and help it with earth." Jiang Wei drew a line, and the river worker who was in charge of writing the landmark drunkenly spoke.

The river worker scratched his head and said, "Brother Jiang, it's obvious that the south side is higher than the north side, is the water level still up if you still help here?" ”

Jiang Wei shook his head and said: "What you see is only the surface, sometimes seeing is not necessarily believing, the south side is just a mountain bulging outward, which makes people think that the south side is protruding at a glance, I don't believe you go to the actual measurement to know where it is high and where it is low." ”

Hearing Jiang Wei's words, the river worker was speechless for a while.
