The wasteland that once belonged to Xu Yu was surrounded by a wall.

The wall is made of bluestone, and every twenty or thirty steps, there is also a guard tower.

Dozens of men and women are busy clearing weeds.

Recruited stonemasons and carpenters are also in full swing to build infrastructure and masonry walls.

Zhen Yan accompanied Yuan Xu and others and walked on the ridge.

Not far from them, there was a pond that had just been dug up.

"Did you put the shrimp fry in the pond?" Looking at the pond, Yuan Xu asked.

"It's already in." Zhen Yan replied: "I really haven't seen the shrimp given by the child, it's red, and it looks quite vicious." ”

"Alien species, of course you haven't seen them. What Yuan Xu ordered him to put in the pond was actually a crayfish that sold well two thousand years later.

Crayfish is not a Central Plains species, it can adapt to very harsh environments, and it is extremely reproductive.

In the absence of natural predators, it will not be long before it becomes a scourge.

Bring it to the end of the Eastern Han Dynasty, of course, together with the cooking techniques.

No species, no matter how fertile it is, has no chance of becoming a disaster as long as it is deemed to be edible.

"How are you going to plan the fields?" Standing on the ridge, Yuan Xu asked Zhen Yan.

"I plan to plant all novel crops as Childe explained." Zhen Yan replied: "Spices occupy less land, and more land is used to grow tomatoes and other crops. ”

Speaking of tomatoes, Zhen Yan subconsciously swallowed his saliva.

He clearly remembered that when Yuan Xu set up a banquet, there was a dish called tomato scrambled eggs.

The taste is pure, and he still has a long aftertaste.

Yuan Xu nodded: "Is there a plan for the farm?" ”

"It's been planned, but it's not decided where to build it yet." Zhen Yan replied: "There are too many chickens, ducks and geese on the market, and I don't really want to invest in them." I'm going to raise some turkeys and ostriches that my son once mentioned. ”

"Turkeys and ostriches are very valuable, they are not easy to raise, and it is difficult to sell." Yuan Xu reminded: "You can think about it. ”

"It is precisely because it is worth a lot of money that it is necessary to raise it." Zhen Yan replied: "If others can't sell it, I can still solve it." ”

Yuan Xu nodded: "Selling goods, you are indeed very strong." I also believe that it can be sold. ”

Zhen Yan replied: "With the full support of Gongzi, the farm will definitely be prosperous." ”

"Whose land belongs to the neighborhood?." Yuan Xu looked outside the wall that had not yet been closed.

"It's all terra nullius." Pang Tong replied: "In the past two years, many people have left Yecheng. Although there is a return, many of the old owners of the land are gone. ”

"Plan another 4,000 acres for the farm." Yuan Xu commanded.

"There is land nearby, but it is very barren." Pang Tong reminded: "Do you want to change the child?" ”

"The poorer the better." Yuan Xu said: "Fertile land is used for planting, and barren land is used for breeding. ”

He pointed to the wasteland outside the fence and asked Zhen Yan: "What is the plan of the farm there?" ”

"There will definitely be no mistake in the place chosen by Childe." Zhen Yan replied.

"Tomatoes and other crops, you can't always count on them." Yuan Xu reminded: "The farm should be high-end, and the crops that are easy to grow will be spread sooner or later, and once they appear in the market, the value will fall below the bottom line." You need to plan ahead so that you can grow more valuable crops and raise more expensive livestock. ”

"I remember what Childe confessed." Zhen Yan should go down.

"How many days will it take?" Yuan Xu asked.

"More than a month." Zhen Yan replied: "The wall will be closed in a few days, and crops can be planted in the field first." ”

"The seed was given to you a long time ago." Yuan Xu nodded: "You have to plant it in time." ”

Coming to the river, he looked back at the fields: "How are you going to irrigate?" ”

"Manpower." Zhen Yan said: "The people in the farm are all slaves transferred by me from the Zhen family, and they have endured hardships......

"It's just that it's going to suffer." Yuan Xu said: "You also have to know how to cheat. ”

"Tricks?" Zhen Yan was puzzled: "Childe is talking about stealing and playing tricks?" ”

"Stealing and tricking are two different things." Yuan Xu said: "For example, irrigation. How much can manpower carry water in a day? In the summer, the water that was poured out soon dried up. ”

"That's what the people have always done." Zhen Yan said: "In the past, the land of the Zhen family also relied on slaves to carry water for irrigation. ”

"I can't count on carrying water, and I can't do it with so many people." Yuan Xu waved his hand: "Breeding and planting all need manpower, and people are used in critical places." As for irrigation, what can be done by one person, why use so many people? ”

"Alone?" Zhen Yan was even more dazed.

Throughout the ages, irrigation in the fields has always relied on manual water picking, and I have never heard of a single person who can do it.

Yuan Xu said to him: "Arrange people to dig canals along the ridges, and they must be high by the river and low on dry land. After the canal was dug, a water pressure was built by the river. Every day, one person can pump water from the river into the canal. ”

"Water press?" Zhen Yan had never heard of such a thing, of course he couldn't imagine it.

"You don't have to think about it, I'll find a blacksmith to build it and send it over." Yuan Xu greeted Pang Tong and Tian Feng, who accompanied him: "Let's go back to the city." ”

Leaving the farm under construction, Tian Feng asked Yuan Xu: "What is the water pressure that Gongzi said?" ”

"I was going to build a waterwheel, but it's stupid and mediocre." Yuan Xu replied: "There is no water pressure to come directly. ”

He gave an explanation, but Tian Feng was confused.

Pang Tong didn't ask, and his expression was also puzzled.

They really didn't understand what Yuan Xu was talking about about the water press.

Yuan Xu once lived in an era when electric pumping machines and tap water were popularized, but there were still some backward areas, and water extraction was still using kill wells.

A steel pipe pestle is fed into the well, and there is a crank that is raised and pressed.

The operating crank can use the principle of vacuum caused by air expansion and compression to lead water to the ground.

The same thing is placed next to the river, and as long as the structure is changed, the purpose of taking water and irrigating the ground can be achieved.

Yuan Xu knew it in his heart, but Tian Feng and Pang Tong had no concept at all.

After entering Yecheng, Yuan Xu instructed the guards: "Find a few skilled blacksmiths to come over." ”

The guards searched for the blacksmith, and he, accompanied by Tian Feng and Pang Tong, returned to Yuan's house.

Tian Feng and Pang Tong were waiting in the front hall, and Yuan Xu went to the study.

Putting on the ghost harp, he stroked the strings.

The black gas filled the air, and several shadow-like necromancers appeared.

The sound of the piano is long, and the necromancer lingers for a moment before disappearing.

When they reappeared, a drawing was placed on the table in front of Yuan Xu.

The diagram depicts the kill structure.

It is impossible for the craftsmen of the Eastern Han Dynasty to have read books, and the manufacturing process is mainly based on experience transfer, and their understanding of language descriptions is limited.

The structure of the well is too complicated for them, and it is better to get a drawing directly than to explain it verbally.
