Of course there is nothing wrong with it.

And the other party may be a high-ranking official in the court.

Yang Hao led the people out of the house, and pointed at the front while walking, saying, "There is the wasteland given to me by the imperial court."

Li Shimin looked up and said, "It seems that someone is logging wood on the mountain?"

"Yes." Yang Hao nodded and said. "Although the wasteland is large, most of it is mountainous. There are many trees in it. I hired a short-term worker to cut down all the trees on the hillside with smaller slopes and plant grass in the future."

"Yang Liulang, can you raise cattle?"

"I understand a little bit." Yang Hao really understands it. After all, he has been in the space for eighteen years, so he knows something. " Raising livestock is nothing more than giving them full food, trying to eat well, living a comfortable life, and finally preventing infection."

When he heard what he said was empty, Li Shimin wanted to ask more questions, but he found that he didn't know where to ask. Because he knew nothing about raising cattle.

Forget it, let’s take a look anyway. Let’s watch it in the future.

He laughed and said, "I heard that you spent a lot of money to dig a deep well in the stone layer. The well water was so much that it overflowed automatically?"

"I happened to be digging a spring." Yang Hao said with a smile. "Our village is actually on the edge of the Zhongnan Mountain Range. Zhongnan Mountain is high and dense, with excellent water and soil conservation. The spring in that well is probably connected to a water reservoir on the mountain. The terrain on the mountain is high, and when you come to the foot of the mountain, the water will rise high."

"But I heard you can see water veins."

Yang Hao blinked and said, "I understand a little bit, and I can only look at this type of water vein."

He said nonsense: "Actually, before I had time to learn from my master, he went to immortality. I think there are water veins there, but the situation there is just the same, which is very similar to the terrain of a water vein that my master once pointed in Tochar.

"I asked someone to dig wherever I was just trying my luck. I said I could look at the water veins, but I wanted my father not to stop him."

Li Shimin smiled, not saying whether he believed it or not, but asked another question that was easy to die: "You dug that well. But I see that Guanzhong is going to be drought?"

Of course, this problem cannot be told the truth.

Yang Hao thought for a while and said, "I don't know how to look at those. I dug a well but I just think about the fields I have suffered and the fields my father distributed to me are difficult to irrigate. And I plan to build a house there, which is far away from the wells in the village, so it is not easy to carry water."

"But you also stocked up a lot of food. Although you hired more than a hundred people to do work and wanted to pack their food. But as far as I know, the food you stocked up is enough for them to eat for at least two years."

Yang Hao laughed and said, "I heard from the old man that Guanzhong usually has three droughts and one flood in ten years, and there may be insect plagues. I just came back and didn't have any stock... I bought grain, but I was prepared for any trouble."

"It's really just a precaution?"

"Do not believe it or not, I believe it anyway!"

Li Chengqian chuckled.

Li Shimin was also angry at his scoundrel words: "You should think you are really prepared for any trouble. Now in Hebei, spring drought is a foregone conclusion. Have you ever seen ways to relieve drought conditions?"

Drought resistance?

This is a big proposition.

Yang Hao knew many ways, but the Tang Dynasty could not do it.

On the contrary, he didn't know much about the technical situation of this era, but he didn't know what to say.

"What, but have any doubts?" Li Shimin said with a smile.

Yang Hao pondered and said, "Why did Langjun Li ask these questions?"

"I just don't want to see the people in the world who are unable to eat or even divorce their wives and children."

"Langjun Li is compassionate to the world..." Yang Hao said that if that happens, he would not even believe in punctuation.

However, the other party was unwilling to disclose his identity, so he just didn't ask.

Anyway, this person's temperament that has been in the top position for a long time cannot deceive people.

He thought about it and felt that there was nothing to say: "I have indeed seen some methods. However, the disaster relief and production I have seen require the lead of the court and the government to be effective."

"Oh, let's hear it."

Listen! Listen to this tone...

It's like saying: Come on, give me a smile.

However, Yang Hao had no choice but to worry about him and said, "Now, we use surface water to irrigate in Guanzhong, which is the water flowing on the ground, or rainwater.

Li Shimin thought for a while, nodded and said, "It's true."

This is the case, but no one has ever described it like this. Perhaps this is what this kid said is good at summarizing.

Yang Hao continued: "And every river and stream flow through, the people along the coast must use it. When the water volume is abundant, it will be fine. If there is a drought and insufficient water volume, the upper rural areas block the river and store water, and the lower stream will inevitably have no water use.

This is also the truth. During drought, there will be water fighting in various places.

"And of course how to solve it?"

"Blocking rivers and storing water is actually a good way to resist drought." Yang Hao said of course it is not a big dam. The Tang Dynasty's technology cannot be achieved.

But it is still OK to build some small reservoirs.

"I wonder if Mr. Li can go to Danbi several miles west of Zhen County?"

Li Shimin suddenly realized and said, "Are you talking about letting the government build dams to store water during the flood season and release water during the dry season?"

"It's exactly this. But Danbi is looking for a low-lying place to accumulate water on the flat ground, and there are not many suitable places. The most suitable one for water storage is in the valley."

He stopped, turned around and pointed at the mouth of Gangu, and said, "If you build a dam in Gangu, you only need to choose the narrowest place and build a three or four-meter-high embankment in the valley. A small lake with a much larger water storage capacity than Danbei can be formed in the valley.

"It is under the jurisdiction of the government and court. In the event of a drought, it can ensure that there is water available under the Lao River."

"I'm afraid it's a lot of money."

Yang Hao smiled and said: "Spend money must be spent, but it must be worth it. As long as you build a dam well, it will benefit at least a hundred years downstream. What you should be afraid of is not spending money, but being good at coups and chaos."

"Why did Yang Liulang say this? Will the construction of a dam become a disaster?"

"Why can't it turn into a disaster?"

Yang Hao sneered: "I am afraid that local officials will build randomly for political achievements or to make profits from it. You must know that before building dams, you must understand the historical hydrology of the river.

"What is the maximum traffic in a hundred years, or even a thousand years?

"Where can be built, how can we ensure that the dam will not collapse for hundreds of years, or even hundreds of years.

“These all require statistics and calculations.”

Yang Hao smiled and shook his head, saying, "What do I say?"

Li Shimin became interested: "Why don't you say it? The court worked hard to govern. If it makes sense, maybe the court adopted it and you can still make a contribution. Moreover, you said it too. That is a good thing that benefits all the future."

"This good thing needs to be done well, that's a good thing."

Yang Hao felt that he was thinking too much.

If you only build dams in some tributaries, although it is not difficult, it is not impossible to build with the Tang Dynasty's technology.

He thought for a while and continued, "In fact, it is not impossible to repair it. It is just that it needs to be repaired by a specialist. Those who preside over the construction of dams must have skills."

"How do you say this?"

"To build a dam, you must consider how to make it work as much as possible. How high a dam body needs to be built to be suitable, and how can the dam body be ensured not to be washed away by the possible flood. Only those who understand this can calculate it.

"If the layman commands the experts... one day the dam collapses, it may become a death talisman for the people downstream."

Li Shimin nodded and said, "This concern is not an unreasonable worry."

"There are even more worrying." Yang Hao said with a smile. "Large-scale projects consume a lot of money. The more money you spend, the easier it is to get started. If you are not responsible for it, it will be difficult to supervise. Without supervision, he can build a tofu project."

Li Shimin was silent for a while and suddenly asked: "What is a tofu project?"

"It can also be said that it is gold and jade that is outside and it is broken."

Li Shimin learned: "Then do you think if you want to build a dam, what else should you pay attention to?"

"If you really want to repair it, you must arrange a dedicated person to be responsible for maintenance and a dedicated person to guard it. Once a dangerous situation occurs, you can also promptly warn downstream... and there will inevitably be crazy people. If no one guards it, the dam will be destroyed... the consequences will be unimaginable."

What Li Shimin thought of was the water attack tactics that appeared in the history of war...

There are always unruly people who want to rebel - this is something the emperor must always be vigilant about.

Li Shimin didn't say anything and walked towards Yang Hao's residence.

After walking for a while, he said, "As you said, it may take time and effort to repair dams and store water. The world is so big... Have you seen other methods?"

"If it is a small river, there will definitely be no water supply in the drought. However, if it is on the edge of a big river, you can set up a water truck to lift water from the river and irrigate fields slightly far away from the river.

"If the distance is too far and the terrain is high, this method cannot be used.

"But you can also mobilize the people to dig one or two acres of ponds from their own fields. Digging out the pond can store water on rainy days, and when there is a drought, you can lift water from the pond. It can also slightly alleviate the drought."

"Why isn't it a well?"

"In drought, it's good to drink enough well water."

The amount of diving is usually not large. If you want to get pressure water, you have to dig through the rock layer. I'm afraid that few families can afford it.

Those who dig the pond, dig slowly, and one day they will be able to dig it well.

"And there are other benefits to digging ponds. For example, you can raise fish, ducks, grow lotus roots, and even aquatic plants and bottom mud can be used as agricultural fertilizers. It can be said that you can kill multiple birds with one stone..."

Li Shimin nodded and did not make much comments.

The other party didn't speak; Yang Hao didn't say much.

He actually felt that this Langjun Li looked like a high-ranking official. He said those words just to give the other person a seed in his heart.

As for whether the seeds can germinate, he...it depends on what will happen in the future!
