In addition to the navigation of ships, Lu Chensheng is preparing to connect the canal with the city.

There is an underground river in the city, which has been gushing water from the outside, but in fact, how long this water can gush, Lu Chensheng doesn't know.

There's water outside, and that's the best thing to do.

Even if one day, the underground river runs out of water, Seonghan City will not face a shortage of water.

Uncle Lin understood Lu Chensheng's plan, and nodded directly when he heard this, "Then I'm going to survey the dock, choose a good location, and start construction directly?" ”

"Well, in addition, this is the latest ship I have come up with, and Uncle Lin will find a way to build it."

Lu Chensheng handed over a drawing, which depicted a combination of a kind of ancient ship, a sail and a waterwheel.

If there is wind, you can just raise the sail, but if there is no wind, you can use a propeller-like waterwheel as a power.

This kind of device, arranged on both sides of the boat, looks like there are more waterwheels on both sides of the boat, which looks a little weird.

But in terms of power, it is extremely easy to use.

This thing...

Uncle Lin took the drawings and looked at them carefully, "Okay, I'll go back to find someone to study this thing and build it as soon as possible." ”

After Uncle Lin looked at it a few more times, he secretly wondered in his heart where the shopkeeper got so many ideas, such a ship would not be weak in terms of power.

If the power is fast, it can replace many ships.

Uncle Lin went to study it, and by the way, he found a place to build the dock, and Lu Chensheng also handed over this matter directly to Uncle Lin with confidence.

The spring planting in the city has begun, and in a large open space, all the green fields in the past are all planted seedlings one by one, and they are fluttering with the wind at the moment.

"Shopkeeper, the Great Cangguo is here!"

Just as Lu Chensheng was about to continue to go to the workshop to have a look, an attendant hurriedly ran over, and then whispered to Lu Chensheng.

Lu Chensheng raised his eyebrows when he heard this, and returned to the main hall with the attendant, this is the place to receive guests, no matter what the other party comes from, it is here to receive them.

"Lu Gongzi!"

Seeing that Lu Chensheng came back, Zhao Qianhua, who came here, immediately bowed his hand.

Lu Chensheng nodded when he saw the other party, and said casually, "Lord Zhao is here, but is there anything wrong?" ”

Zhao Qianhua originally wanted to be polite with Lu Chensheng, but he didn't expect Lu Chensheng to be so straightforward, and he was stunned for a while.

Lu Chensheng was also too busy, and he really didn't have time to be polite to the other party, so he directly asked the other party about his intentions.

"That's the case, the emperor is worried about the flood, so he sent his official to inquire about it."

Mainly after the New Year, the spies explained that after Lu Chensheng came back, he was not going to the Pingyun Mountain Range, but sent the rest of the people, but the number was only about a dozen.

About a dozen people, can such a number of people really cure water?

Now that the money and grain have been taken by Lu Chensheng, and the other party is still mining iron ore or something, the emperor is a little worried, so let people ask.

Lu Chensheng naturally knew the worry in the other party's heart, and waved his hand directly at this moment.

"Lord Zhao don't worry, the water control is ongoing, if everything goes well, Lord Zhao will naturally be able to see the effect at the end of the year."

Lu Chensheng replied, signaling the other party to rest assured, there was no need to worry so much.

Zhao Qianhua opened his mouth when he heard this, "Then, I don't know if I can let this official know the progress of Lu Gongzi's water control method?" ”

Lu Chensheng frowned, looking at the other party's appearance, I was afraid that if he didn't say it, the other party would not give up easily.

Thinking of this, Lu Chensheng replied, "Actually, it is not much different from that of Yunmeng City, they are just diverting and controlling floods, and the diversion place is on the Pingyun Mountain Range, and now everything is not completed, so there will be no change on the side of the Great Cangguo." ”

As soon as Lu Chensheng said this, Zhao Qianhua immediately understood.

The water sources all come down from the Pingyun Mountains, and if you want to control the floods, you can go to the Pingyun Mountains and lead the water down.

Thinking of this, he immediately regretted it, why didn't he think of it before?

Just go to the Pingyun Mountains, dig a river, and divert the water away, so there will be nothing to do? Instead, he found Lu Chensheng and gave Lu Chensheng so much silver.

"What, Lord Zhao thinks this is an easy job?"

Lu Chensheng looked at Zhao Qianhua's appearance, where he didn't know what Zhao Qianhua was thinking, and shook his head again and again at this moment.

"Lord Zhao knows, this water is not casually dug up, a canal is very easy to dig, but after the river is dug well, the impact of the water potential accumulates over time, if Lord Zhao does not dig well, the river canal dug will become bigger and bigger, and it is normal to change the river channel over time.

At that time, the Great Cangguo was originally a flood, and I am afraid that it will become a drought after that. ”

Digging a river is easy to say, but it's not that easy.

Under the continuous impact of the water, it will carry away the sediment on the bank of the river, and with a little impact, some of the sediment at the bend of the river will be carried away, and some places will silt up.

After that, the river was directly diverted, which is also a normal thing.

So, it's not that simple.

If the other party wants to build a dam on that lake, it is even more whimsical.

Where does Zhao Qianhua understand these things, when he heard Lu Chensheng say this at this moment, he was stunned for a moment, and he didn't know what Lu Chensheng meant at all.

It's just that the general meaning, he heard it clearly, that is, you can't dig casually.

In this way, it is easy to affect the water conservancy of Yunmeng City.

Hearing this, Zhao Qianhua couldn't help touching the sweat on his forehead, it seems that this flood is really not something that can be treated casually.

If he doesn't get it right, he will turn the entire Great Cangguo into a dry country, and he will become a sinner for the ages.

"The official understands, so he will go back to report, and ask Lu Gongzi to be able to control the water and bother more."

Zhao Qianhua got the answer, and seeing that Lu Chensheng seemed to be very busy, he was ready to retire.

"Take people's money and do things for others, and naturally they will do this well."

Lu Chensheng nodded seriously, sooner or later, the Great Cangguo will be his own, and this flood will naturally have to be seriously managed.

Otherwise, you will have to do it all over again in the future? Lu Chensheng felt that he didn't have that much time.

Where did Zhao Qianhua know Lu Chensheng's thoughts, and when he saw Lu Chensheng said very sincerely, he would take care of this flood, and he was relieved a lot, so he turned around and left directly.
