A group of people walked towards the outside of the city, this Yunmeng City is extremely prosperous, at a glance there are people coming and going, and there are countless wine shops and teahouses.

Once out of town, it's even more lively outside.

The number of rice transplanters is very large, and the rice fields are full of young seedlings, and the tender green looks extremely pleasing.

If you wait until the harvest in autumn, the golden ears of rice are bent over, I am afraid it will be even more beautiful.

"What a fertile land."

Lu Chensheng couldn't help but praise it at a glance.

When Lin Gu heard this, he couldn't help but nodded, "Yes, if the flood is calm, this place must be the granary of Jiang Guo." ”

Lu Chensheng nodded when he heard this, such a fertile land is extremely flat at a glance, if there is no flood, there will only be more and more people who will come to settle here in the future.

A moment later, the group came to the incomparably wide Yunjiang River, and the water of the Yunjiang River was rushing towards the front.

Now there is no flood, and the water of the Yunjiang River seems to have the momentum of thousands of troops galloping in it.

Lin Gu looked at this Yunjiang, and a look of sorrow swelled up on his face.

Lu Chensheng watched for a moment and walked upstream, muttering silently along the way.

After walking for more than an hour, I saw a forest of peaks in front of me, and I had to walk a path to enter the mountain.

Lu Chensheng stood on the bank of the river, looking ahead, what he saw was still straight and smooth, seeing this scene, Lu Chensheng immediately shook his head again and again.

"How?"

Lin Gu shook his head when he saw Lu Chensheng, and hurriedly asked.

"This river is rushing all the way, the potential energy is constantly accumulating, once the flood will only become more and more ferocious, the river must be diverted, meandering forward can reduce the impact of the water.

It's like when the cavalry is coming towards you, if you are in the alley, the cavalry will be able to find you, and even if you find it, the impact of the cavalry will be gone. ”

"Then according to Lu Xiucai's meaning, how should it be treated?"

Lin Gu suddenly came to his senses when he heard this, just this sentence, he could hear that Lu Chensheng did have some insight, and even if he asked.

"Cut off the mountain and block the water, make it diverted, and use the dynamics of the water flow curve and the natural law of the water flow to carry out flood and sand discharge and automatic water control."

Lin Gu was stunned when he heard this, and the girls on the side also looked at Lu Chensheng with a confused face at this time.

I can hear the first few words clearly and understand, and I know what Lu Chensheng means.

But what does Lu Chensheng mean by what he said later? What is the dynamics of water flow curves? This natural law of water flow? What is the law?

They only know that the water goes low, and what is the rest of the rules?

And this automatic water control? What is automatic water control?

Lin Gu swallowed a mouthful of saliva with difficulty, feeling that his decades of books had been learned in vain, and he just couldn't understand what Lu Chensheng was saying!

"What is the dynamics of water flow curves? What is the natural law of this flow? ”

Lu Chensheng looked at Lin Gu's face with a strange look, and reacted that the other party didn't know this knowledge point at all.

"Curve dynamics, this is actually very simple, it's like we are sitting in a very fast carriage, once the carriage starts to turn, we will involuntarily fall to the other side, and this water flow is the same, this is the curve dynamics, we can use this to control the water."

What Lu Chensheng said was extremely simple and easy to understand, and when several people listened to it and thought about it carefully, they immediately understood what Lu Chensheng meant.

It's just that what shocked them a little was that Lu Chensheng could still apply this simple matter of sitting in the carriage to the flow of water?

This is really as clever as a demon!

Several people looked at Lu Chensheng's eyes, full of different colors.

"Where do you start to break the mountain?"

Lin asked once, knowing that what Lu Chensheng said was definitely not playing tricks, so he asked more sincerely.

"Let's start with that peak."

Lu Chensheng just looked at the map, although the map was a little rough, but at this time, the two were combined on the ground, and after corresponding, Lu Chensheng immediately had a plan in his heart.

"Which place?"

Lin Gu's eyes narrowed slightly, and then he was a little helpless.

"The top of that mountain is full of boulders, and it's hard to chisel through."

"If there is not a boulder, it will not be needed below."

Lu Chensheng said with a smile, what you want is not a boulder to be thrown, and it is a cliff, is it just enough to block the water?

If this is replaced with dirt, it will be washed away.

"But, how do you chisel it?"

Lin Gu muttered to himself, I'm afraid that it will be difficult to pass this level of digging boulders, the mountain rocks on this are extremely hard, and there are many rocks.

"If you set it on fire, you will be watered with water, and the rocks will naturally be fragile, and if you are lucky, you will explode."

"What is an explosion?"

...

Lu Chensheng glanced at this Lin Gu a little helplessly, "After the adults try it, they will naturally know." ”

Lu Chensheng personally determined this place, drew some more peaks on the map, and then went back together.

And Lin Gu also left in a hurry, and he wanted to gather people to start construction.

Lin Gu's side began to prepare for the construction of the building, and the city lords and county officials in Yunmeng City also knew about it, and they all looked at each other at this time.

"What do you think? This governor costs a lot of money to control the water. ”

The city lord sat on top, groaned and looked at the officials below.

"This water control has gone back and forth so many times, I'm afraid that it will be useless when the time comes, so I'd better sit on the shore and watch the fire."

The county man thought about it and opened his mouth to speak.

As soon as these words fell, the county lieutenant on the side immediately refuted.

"I'm waiting for the parents of Cloud Dream City, if we don't do our best to control the flood, will you and I be able to escape once the flood happens!

And no matter whether the other party is good or not, once we don't do our best, this governor will go up and take off his skin even if he doesn't die!

What's more, if the flood of the Yunjiang River is not solved for a day, how can you and I be able to do it safely! ”

The county lieutenant is aware of the past of this Yunmeng City, and in his opinion, if this flood is not solved one day, their position will change at any time, not to mention, it is possible to be impeached and imprisoned one day.

The county lieutenant's words fell, and the rest of the officials on the side were silent, and then they all nodded helplessly.

Yes, this flood is a thorn in their hearts, and if this matter is not solved, they will have some trouble sleeping.

"In that case, let's do our best."

The city lord made a decision at this time, "Except for us, we need to take out two taels of silver for this flood control, and by the way, we are gathering the rich merchants in the city, so that they can also contribute money to jointly control this flood." ”
