Zhang Han finally calmed down the emotions of his mother and others, but when he was leaving, he took out a sketch from his arms and handed it to Chang Jinquan to read.

"That's it, so it looks big?"

"Well, the diameter is more than two feet high."

Zhang Han in his hand is a sketch of a big waterwheel, this thing also appeared on both sides of the Yellow River after the middle of the Ming Dynasty, this is a good thing to take water, almost day and night to take water, is the crystallization of the wisdom of the people in the water-scarce areas on both sides of the Yellow River, Zhang Han has seen the real thing when he travels in later generations, and he was amazed at that time, but such a good thing has not spread at all, whether it is a place with a river or a very water-scarce area, there are few such big waterwheels, one is difficult to build, the second is costly, and the third is that no one has taken the lead in promotingAt this time, the Ming Dynasty, information dissemination was only faster among scholars, in the people, fifty miles away from the village is to go far away, only a few people in a hundred people are literate, and this literate person has few opportunities to enter the gentry class, and rarely has the opportunity to accept information dissemination, so it is like another world across hundreds of miles, not to mention that many people have never heard of it, even if they have heard of it, they are powerless, and they have no ability to create such a thing.

Technology, manpower, material resources, and determination are all indispensable.

Chang Jinyou's eyebrows widened, obviously very happy, flicked the drawings in his hand, and said with a smile: "Leave this matter to me, I will definitely do it for you!" ”

Zhang Han's farm has more than 5,000 acres of land, most of which are dry fields that are inconvenient to get water, but a lot of land is not very far from the river, a large waterwheel is built, using water power to draw river water, send it to the ditch, and enter the acres of land, a waterwheel can irrigate about 500 acres of land, although the cost is not expensive, but how to calculate it is also a million profits.

Zhang Han plans to first transform his own acres of land, if there is an opportunity to buy a large amount of land, select and breed good seeds, plant sweet potatoes and corn and other crops, increase the yield to solve irrigation and fertilizer, so that the grain output in this area will be greatly increased...... Buying grain is one thing, and when a large-scale natural disaster strikes in a few years, it may be more difficult to buy grain, and it would be best if you had mastered a large grain-producing area.

Fortunately, there is a considerable plain and Yanghe River on Datong East Road that can be used for irrigation, and if the natural environment is worse, Zhang Han will give up.

"I'm tired of my uncle......" Zhang Han said with a smile: "Guan Zhuang is Li Xiangfu Lao Li, I have sent him a letter, he will listen to his uncle for everything, and Li Changnian, he is the head of the craftsman who makes utensils, I asked him to take people to listen to his uncle's orders, and find Zhang Chun for the silver, I have already approved him for three thousand taels of strips and sons, if it is not enough, the uncle will ask him to go to the silver treasury to receive ......"

"Three thousand taels ......" Chang Jinquan shook his head on the side, and said dissatisfiedly: "It's just nonsense, three thousand taels is enough to buy grain, make a water wheel, isn't this nonsense." ”

"You know what." Chang Jin is like a child who has just gotten a novelty toy, and immediately turned his face and said: "With such a waterwheel, the people are no longer afraid of drought, and the things that benefit the people can be compared with silver." ”

"Big brother, I think you just want to have fun......"

"In front of the juniors, don't talk nonsense."

Chang Jin made a flick of his sleeves, everyone else laughed, even Chang Ning pursed her lips and smiled, shaking her head slightly, she couldn't be clearer about her father's thoughts.

"Guys, I'm leaving."

Just now one by one, Zhang Han will not say more, he turned over on the horse, his eyes swept over, and finally saw the faces of Chang Ning and Yang Liu in the crowd, his heart was soft, almost wanted to get off the horse again, but this feeling of children's love was finally defeated by reason, the horse whip in his hand waved, the horse rushed forward, and in the blink of an eye he went out of the alley to North Street, everything on the street was as usual, Zhang Han's destination only a few people knew, and those who saw him only thought it was another ordinary trip, Not too many people cared, only a few shopkeepers happened to be at the door, greeting Zhang Han from afar, Zhang Han didn't have time to return the gift, and when those people chased them out to see, Zhang Han rode out of the dust, and he was already far away from many people.

……

"The front is the East Sixth Store, stay there for one night, get up tomorrow morning, and go to Zhangjiakou at noon."

Liang Xing has been ordered to patrol the branches many times, manage the dart masters in various places, the situation and distance of the various branches are very clear, he is a natural good guide, the temperament is also witty and humorous, like to laugh, the person who speaks out of the tiger, there is a breath of unstingy breath on the body, even if it is changed, it can not be changed thoroughly, this way down, Sun Jingting and Liang Xing have established a shallow friendship, Chang Wei is behind the two big brothers, running before and after the saddle, this kid has a sweet mouth and strong eyesight, and the friendship with each other is not shallow in a few days, With Chang Wei here, I don't feel lonely, listening to this kid giggling every day.

Sun Jingting is in the east of the shop and Zhang Han and his party converged, he took two servants, a total of three people, Zhang Han with Chang Wei and Liang Xing, Li Dongxue and others, the escort accompanied by more than 20 people, a total of 33 people, the team is divided into three sections, the front is Duoer and Wang Yikui a few people as a beam, the back team is Li Laibin and the Zhao family brothers escort the tail of the team, the middle of the 20 people can act calmly, and a few horsemen who are good at riding were ordered to Tang Ma, they are responsible for reporting and giving orders back and forth in the three teams, and also have the responsibility of a sharp whistle, In case of any mutations and conflicts, they can join up with the Beam or the Rear Team for a while.

This time, almost all of the people Zhang Han brought out were first-class good players, and the skills of the dart masters were not much weaker than those who did not collect the night, and the two sides actually had some heart, and they competed with each other in riding skills first, and after a few days of hard work, they touched each other's bottom, and the arrogance of the night masters was restrained a lot.

The middle team was mainly composed of the dart master and Zhang Han and others, and each of them, including Chang Wei, issued a firecracker.

In the past few months, Wang Debang has not wasted, each fire gun is carefully made and rolled, the iron is the best Fujian iron, the materials are sufficient, the process is becoming more and more refined, and each gun is very heavy in his hand.

"The gun weighs seven pounds and six taels, is six feet four long, four dollars for medicine, and three dollars for bullets...... What a gun, what a gun. ”

Sun Jingting straddled and rode on a horse, holding a firearm in both hands, chanting words in his mouth, looking intoxicated and fanatical.

Just when he was resting at the tip, he loaded the fire gun and sent it a few times, these days as long as Sun Jingting rested every time, he took a companion, the horses were taken care of, and the diet was also taken care of, and there was no need to do everything himself, so he had time to study the fire, Sun Jingting didn't think so, and the ordinary scholars of the Ming Dynasty, Sun Jingting did not agree with firearms, and did not have a real understanding of the safety and power of firearms, when he hit the first stone on the side of the road, when the gravel burst out within dozens of steps, That kind of jaw-dropping look, Zhang Han still felt funny when he thought about it a few days later.

There are some things that are useless no matter how much you talk about if you don't do it yourself.

In the twilight, the East Sixth Store is like a monster across the north end of the road, you can see a huge building complex from afar, the whole East Sixth Store not only has the source of customers from Datong here, but also the crowd of people who come to the south of Jizhen to hit the tip, there is an official road obliquely through Zhangjiakou, just here and the official road of Datong intersects, and the final point is Zhangjiakou, at this distance of thirty miles, once you miss the time, it is best to hit the tip here, many cautious businessmen do not say that they do not rush to the night road, Even after the afternoon Shen Shi will never be on the road, as soon as the business comes out is half a year, a year or even a few years, I don't care about such a little rush time, when the end of the world, all kinds of chaos have risen, the businessman's sense of smell is the most sensitive, no matter what, it is safety first.

In this way, the business of this branch is very good even if there is no support from Datong, after eliminating the group of bandits of the Zhou brothers, Datong business has become safer, and the number of businessmen from Datong has also soared.

"Bang!"

In the twilight, there are more than a dozen lanterns hanging at the head of the door of the East Sixth Store, of different heights, scattered, and the dusk twilight, there is a complex feeling of desolation and warmth, everyone is watching the situation in front of the store from a distance, but there is a loud noise on the side, everyone looks back, Chang Wei is smiling and retracting the fire gun in his hand.

"Chang Wei," Zhang Han said majestically, "next time you do this, take back your firecracker." ”

"Brother Han, I don't dare." Chang Wei has an advantage, he listens to what he says, and he can change his mistakes.

He responded first, then put the fire gun in the pocket, and after seeing Zhang Han nodding, he smiled and said: "I just changed the scattered iron sand, and I saw a flock of birds in the treetops, so I couldn't help but shoot it, and I want to roast it at night......

Zhang Han smiled: "I know that your kid has a demon moth, why don't you hurry up and take a look, how many are down?" ”

"Uh-huh!"

Chang Wei happily agreed, Le Ma ran in the direction of the woods in the south of the road, Zhang Han looked at his expression, I am afraid that he is usually detained by Chang Jinquan, and then he came out, although he is sensible, after all, he is still a half-big child, there are firecrackers, there are birds, he can endure not fighting, then it is not this age.

He didn't think about himself, he was too mature, and no one in the team thought that he was more than two years older than Chang Wei.

At this time, the gong suddenly sounded on the side of the East Sixth Store, and in the rapid sound of the gong, the door of the store was closed, and there were several places on the roof of the front where people could stand, almost in the blink of an eye, and there were figures in these places, each of whom was either holding a bird gun or a bow and arrow in his hand, and they were standing on a high place looking at this side, and the weapons in their hands were also pointing to this side.
