Lu Chensheng was stunned for a moment when he heard this, but he didn't expect the other party's association to be so fast.

"Well, if you build a dam with this kind of technology, it will naturally be much safer."

Lu Chensheng nodded, and with the cement and hydraulics, the embankment was built into an oval arch shape and the force was distributed to the shore.

In this way, the embankment will naturally be much safer.

Du Rufang had already seen the thickness of the city wall just now.

I didn't think much about it before, but now when I see this kind of thing on the ground, just this kind of thing is already so hard, and I immediately have an ideal.

Listening to Lu Chensheng's admission, his face was surprised and happy.

What is surprising is that Lu Chensheng actually had a way to control the water early on, and he is happy that he also knows this method.

It's just that there is no such material now, so what can you do if you know it?

Soon, a basin of water was splashed, which cooled Du Rufang's mood a lot.

"If you want to build a dam in this way, you don't have to think about it for the time being, the dam is not so easy to build, and there are actually a lot of harms to build, and the best way is to dredge the canal."

Lu Chensheng said directly.

The forging of cement materials is extremely difficult, and now it is naturally impossible to give it to the other party to build a dam, and Lu Chensheng himself is not enough!

In addition, it is really not good to build such a levee.

According to Lu Chensheng's proposal, it would be better to find a way to dredge it.

Du Rufang was a little disappointed when he heard this, according to his own ideas, it was naturally better to treat the water well.

Even if he has been demoted, it is not so easy to disperse after serving the country with all his heart.

However, it was not easy for him to force Lu Chensheng, knowing that Lu Chensheng had almost been poisoned before, which was even more difficult to say.

"Let's go ahead and have a look."

Lu Chensheng opened his mouth and continued to walk towards the front with the other party.

Du Rufang nodded, looking at Lu Chensheng on the side, his eyes flashed slightly.

"Brother Lu, according to the level of construction you have in this valley, there is actually a lot of room for development, and now you are recruiting people around, as well as buying food, etc., in fact, the emperor and they all know.

It's just to ease the relationship with you, so I didn't cut off these channels, and I hope that Brother Lu can remember these kindnesses to some extent. ”

Lu Chensheng recruited people from Dacang Kingdom, and the people came to this Star Han City one after another, will the people above not know?

Of course it can't be, in fact, we all know.

It's just that the floods in Dacang Country are serious, and the person who can control the water at the moment seems to be Lu Chensheng, and Lu Chensheng is the most promising person.

Therefore, he did not let people cut off these supplies, and prepared to ease the relationship with Lu Chensheng, and when the time was ripe, he was looking for Lu Chensheng to help, begging for this water control.

In this way, the success rate will be greatly improved.

Lu Chensheng paused slightly as he listened to his footsteps and smiled slightly.

"In addition to this, there are actually many people who can make money here, so you can't arbitrarily break the reason in it, right?"

The things you bring back from Xinghan City can make a lot of money.

Dirty salt, that's a big head, and then there's paper, and then there's soap and stuff like that.

In addition, since Lu Chensheng has now completely opened up trade with foreign tribes, some furs and other Lu Chensheng will be sold to these merchants.

Now when you come to this star seoul, you can earn a lot when you go back.

Behind these businessmen, there are some shadows of some people.

cut off these supplies for Lu Chensheng, unless they themselves don't want to make money.

Why did Lu Chensheng set the price lower so that these businessmen could make money?

In order to tie their interests together.

If they were ruthless, they could naturally give up such a piece of meat, and then completely cut off some of Lu Chensheng's supply.

For example, ore, grain, timber and other materials.

But the problem is that Lu Chensheng is not doing anything else at the moment, and all he can bring to them is money.

Naturally, it is impossible for them to have a bad relationship with Lu Chensheng so casually.

Not to mention the Great Cangguo, even the same is true for the Jiang Kingdom.

Jiang Guo's treasury is empty, and in order to make money, he only turns a blind eye to some of Biansai's behaviors.

Anyway, it was a trade with Lu Chensheng, and items such as food were not for foreigners, which made some people feel more at ease.

According to the statistics before the fifth day of the Lunar New Year, some businessmen from Jiang Guolai have become more and more appetizing in recent times, and even directly asked if there were any fireworks and other goods.

Lu Chensheng guessed that Jiang Jinjing might be behind this scene.

You can make a lot of money by selling things to Lu Chensheng, and you can make a lot of money by taking Lu Chensheng's goods back.

Such a speed of making money made Jiang Jinjing temporarily give up the idea of dealing with Lu Chensheng, thinking about making money first.

Hearing Lu Chensheng say this, Du Rufang's face was a little embarrassed.

Because Lu Chensheng is right, now that the emperor wants to cut off the supply to Lu Chensheng, it depends on whether the ministers are willing or not.

What if the emperor forcibly orders it?

The people below are against the law, or they are allowed to let the merchants go, and they should make the same money.

The emperor can't help it.

This Lu Chensheng was much smarter than he thought.

"Why, aren't you surprised why I know?"

Lu Chensheng shook his head, "Those ministers eat a lot of inside and outside, and some of them even take risks to sell blades and armor for foreigners. ”

Foreigners don't know how to smelt iron, they can't make weapons, how do they get these blades, arrows?

Some of them were looted, but many of them were sold by these ministers according to their collaborators.

For the sake of silver, these people will do anything to the extreme.

And Lu Chensheng is also selling at this time.

Lu Chensheng sold it because his wrought iron technology was three generations ahead, and it was only one generation that was sold.

So there's no big taboo.

It's not the same as the ministers.

Du Rufang's face was a little ugly when he heard this, and then nodded helplessly.

What Lu Chensheng said was the truth, this is what he knew, and there were indeed some ministers who were doing such things.

It's just that this matter is not something he can investigate.

"Originally, I wanted to use this matter to let Brother Lu help control the water, but now it looks like a delusion."

Du Rufang smiled bitterly and shook his head, feeling a little depressed.

"Since you've been demoted, why do you keep thinking about these things?"

Lu Chensheng was a little speechless, he was already a civilian, and he still wanted to do so much, and he was uncomfortable.

As he spoke, he continued to walk towards the front with Du Rufang.

"If there's one of the best things in this valley, it's the water dragon in front of it."

The water dragon is the unanimous name of the people, Lu Chensheng heard a lot, and gradually called this name.

Lu Chensheng said, pointing to the water column gushing out in front of him, which was particularly spectacular, and a rainbow could be seen under the sun.
