"But the ancestors were very smart. They came up with a way to control the water, so that the weather in that place has been smooth ever since. This thing is called a weir. When the rainy season comes, the weir will divert the water and discharge the water pressure, causing floods. No longer raging, when drought comes, the weir will also divert the water from the river to irrigate relatively dry areas, thereby ensuring that this plain land has water at all times."

"Although the weir is used to control water, we should learn to draw inferences from one example."

"So, I plan to use the weir in our Zimu River."

The old Dragon King was a little confused when he heard this. He was a majestic king of water, but at this moment, Han Sanqian was giving crazy lessons on water control.

However, he did not show any resistance or disgust at all, but instead learned with an open mind.

"Expand our inlet and nearby areas as wide as you can."

"To give you an idea, let me give you a number."

"For example, at the opening, we set the width to be about ten meters, so the river will flow smoothly all the way."

"But in the process, I'm asking the river's banks to start shrinking."

"It can be nine meters, eight meters, or even directly reduced to one or two meters after reaching a certain distance."

The old Dragon King shook his head, still not quite understanding. Isn't this just a simple process of building a river from wide to narrow? What does it have to do with the mother-child river?

Han Sanqian had long known that he would have such a reaction, so he picked up a branch and drew a word similar to divination on the ground.

In fact, the narrowing of the river does not mean that the entire river has really become narrow.

Han Sanqian just started to leave an embankment in the middle of the river to divert the flow.

It seems that the main river is only about four meters wide, but in fact the real width of the entire river is still ten meters, but the river bank branches off another six meters, forming another river.

In other words, the river channel was gradually divided into two.

"It's just that the other branched river channel was diverted to the other side by the river embankment and was hidden under the ground."

When the old Dragon King heard this, he frowned deeply, but soon he suddenly understood.

"I understand, the so-called Zimu River is to divide the river channel into two. In this case, our project volume has not actually increased, because from the beginning to the end, we are building three river channels."

"It's just that these three rivers were secretly divided into six by us."

Han Sanqian smiled and nodded: "Yes, that's exactly it."

"This method is wonderful. This... this will not increase our workload. On the contrary, it will reduce our workload to a certain extent."

Because originally it may be a direct distance of ten meters, which needs to be dug directly. However, because now there is a river embankment in the middle, the middle part does not even need to be dug. In this way, this does not solve the time and cost. What is it again?

Thinking of this, the old Dragon King finally smiled. JrNovels.com
