"Your Majesty, this is impossible."

After hearing this, Feng Zheng smiled and explained, "First of all, after this object is bonded and solidified, it can be tightly fitted without leaving any gaps. Secondly, I actually added a layer of fine sand mortar to waterproof the different concretes.

"

"Oh? Added a layer of waterproof?"

After hearing this, Ying Zheng immediately smiled, "You are very careful."

"Hey, I'm just a little bit of ideas..."

Feng Zheng smiled.

The two of them stepped forward, and before they could see the dam, Ying Zheng heard a whirring sound, accompanied by a creaking sound.

He took a few steps, stepped forward and looked at it, and was stunned.

Wow?

Good guy!

What a big water truck!

That's right, what a big water truck!

Each of these water trucks is as high as six or seven feet, and it is a whole row!

After these water trucks were hit by the water flow transformed with terrain, they were filled with water buckets embedded in them, driving the water trucks, but they were not fixed. After reaching a height, the bottom of the water bucket was at the bottom.

It was disturbed by a wooden stick and then tilted down. A stream of water poured out immediately and transported it to the distance along the bamboo poles.

"That's ..."

"Your Majesty, that's the waterwheel..."

Feng Zheng pointed and explained, "I used the construction of the embankment to cut off the original water flow and raise the water momentum. Such a momentum can make the water flow heavier and faster, and the water truck can be driven faster.

"

"What about those bamboo tubes? What are the waters to do?"

After hearing this, Ying Zheng continued to ask.

"Hehe, Your Majesty, this water will be transported to various artificial pools in Chang'an Township."

Feng Zheng smiled and said, "Each artificial pool is equipped with some water trucks, which drives the wooden shaft to rotate, so that a lot of things can be operated. For example, the Ferris wheel in the playground is driven by one or two large pools.

The water truck is running."

"oh?"

When Ying Zheng heard this, he immediately smiled, "You are quite innovative... But I feel a little confused."

"Please speak with your Majesty."

Feng Zheng heard this and immediately said.

"You want the water flowing over to drive those water wheels. Then, why not use these big water wheels to directly touch them? Isn't this more strength?"

[Wow? Qin Shihuang is really awesome!]

When Feng Zheng heard this, he smiled immediately, [Even if he has never been in contact with it, he can still ask some key questions directly!]

"Your Majesty is wise, if you can use these waterwheels directly, it will be good."

Feng Zheng smiled and said, "It's a pity that these water trucks have a big problem, which is beyond my reach."

"Oh? But who is it?"

After hearing this, Ying Zheng couldn't help asking.

"Your Majesty, there is always a difference in the size and speed of this water flow."

Feng Zheng smiled and explained, "He can be fast for one section and slow for another section. The speed of the water flow is different. It has too much impact on the operation and workmanship of things, and it is not useful."

"Oh? But that's the case?"

After hearing this, Ying Zheng understood.

No wonder Feng Zheng didn't use such a large amount of water energy directly, so he had to settle for the second best.

That's right, this is also the reason why Feng Zheng gave up the first water energy.

The size and speed of the water flow are not fixed at all.

After all, the river water has never been static!

Moreover, he also wanted to build a large artificial lake upstream and make a large valve, but this is not the Three Gorges.

The terrain here is not that high, the water flow is not that big, and it is still close to Xianyang City and then Chang'an Township, so he can't afford to do too much water conservancy.

Therefore, we can only use this continuous stream of water to carry out work.

"Then, I'll ask you again."

Ying Zheng thought of something and asked again with a smile, "What should I do if the water sent over fills the pool?"

That's right, this water flow is constantly being sent over. No matter how big the artificial pool is, it must be full, right?

"Your Majesty is asking exactly."

Feng Zheng smiled and said, "This water flow can definitely fill the pool. Therefore, I have equipped each artificial pool with safety valves."

"Safety valve?"

"Yes, when the water flows to a certain height and the water flow is injected into the valve, the valve will open, and the excess water flow will flow out, so as to ensure safety."

"Haha, but that's the case..."

Ying Zheng smiled after hearing this.

"Then, I ask you, how much does it save you by using water?"

Ying Zheng looked at Feng Zheng and couldn't help but ask with a smile.

"This, Your Majesty, in terms of manpower, it is OK to save at least a few thousand people every day."

What?

Hearing Feng Zheng's words, Ying Zheng was shocked.

Only these water and wheels can help Feng Zheng save at least a few thousand people every day?

Good guy, that's really good guy!

He saved thousands of people working and eating every day, which really surprised Ying Zheng.

After all, in the entire Chang'an Township, there are only about 10,000 households and the workers who can work.

Feng Zheng’s operation is like this, so there are thousands more people working on it every day!

wrong……

This account cannot be calculated like this.

He doesn't have to prepare rations for these thousands of people.

Not only manpower, but also saves the cost of living!

This is simply amazing!

"Feng Zheng, can such a method be promoted?"

Ying Zheng immediately asked, "If it can be promoted, it will save countless things from the Qin Dynasty!"

That’s right, you can have such an effect in this place. If the entire Daqin can be promoted like this, wouldn’t it save you a lot of money?

"Your Majesty's wiseness can promote one or two..."

Feng Zheng smiled and said, "However, except for Xianyang and Wangji, there is no business in other places. Therefore, it can be beneficial to irrigation of farmland. I am afraid that there will be no more to use for the time being..."

kindness?

When Ying Zheng heard this, he was stunned and thought to himself that this was true.

Nowadays, except for the royal capital area near Xianyang, there is no business or manufacturing in other places. What can this water truck be used for?

It really doesn't work much!

However, when he heard that it could be used for farmland irrigation, Ying Zheng was also comforted.

If it can be beneficial to farmland irrigation, it means it can increase yield!

After all, farmland irrigation has always been one of the chronic diseases of underdeveloped agriculture.

How much farmland is because it is not irrigated in time and is not properly irrigated, which greatly affects the yield.

"Okay, after returning to the cabinet, you will draft a charter, and I will ask someone to first promote water truck farmland irrigation in Guanzhong and Shu."

Ying Zheng smiled and said, "Looking at this thing, you can revive Qin!"

"Your Majesty is wise, I am actually ready!"

Feng Zheng smiled and took out a memorial and presented it with both hands. "But, I haven't thought it completely, so I haven't handed it over."
