Almost everyone has Adam's apple rolling, which is caused by a kind of mentality called greed.

However, Li Shimin was not worried about this kind of greed. Instead, he deliberately encouraged him and once again said meaningfully: "If every acre in the world could increase the yield by fifty kilograms!"

Before Li Xiaogong could make a move, he suddenly saw Chang Sun Wuji rushing over. The old bastard grabbed Duan Lun's hand, squatted down by the ditch with the fat man, gritted his teeth and asked: "If all of us support you,

Can your Ministry of Industry make a replica of this kind of equipment?"

The fat man didn't pay attention to his rudeness. Instead, he made calculations with a serious face. The more than a hundred people present held their breath and did not dare to disturb him. After a long time, the fat man slowly exhaled and said:

"Can be copied!"

Everyone was overjoyed.

Unexpectedly, the fat man spoke again and said: "But you can't imitate it."

Everyone was stunned for a moment.

But he saw the fat man pointing at the equipment in the ditch and said in a deep voice: "If we only copy one or two of these things, the old craftsmen from the Ministry of Works will definitely be able to copy them. But if you want to make them in large quantities, I think the Ministry of Works will make them."

Doing this is putting the cart before the horse."

Li Shimin was thoughtful and suddenly interjected: "Is it because of this iron wheel?"

The fat man nodded.

Li Shimin quickly said: "Gu Zeng got the secret recipe of the iron industry from Gu Tianya. This kind of iron wheel can be made completely."

Unexpectedly, the fat man shook his head slowly and said solemnly: "This is Gu Tianya's iron wheel."

Li Shimin understood immediately.

Everyone present also understood.

Imitation is possible, but who dares to try imitation? Although there was no patent act in ancient times, there was a set of established rules.

Tampering with other people's secret recipes is a form of sworn hatred.

As long as it moves, it will be a fight to the death.

But Duan Lun didn't seem to have finished speaking. He suddenly pushed away Changsun Wuji and stood up from the ground. The fat man looked in a direction from a distance. There was a big river there. He pointed at the river: "The giant Konoha waterwheel, let's

We have seen it before. That thing had already appeared in the Han Dynasty, but the waterwheel we have seen has obviously been modified. It is this modified waterwheel that can pump a huge amount of water into the ditch. Then, this kind of waterwheel is set up in the ditch.

We have never seen a tool that carries out the second and third steps of lifting water up. Haven't you discovered it yet? This is not the effect of a single tool, but the combined effect. Without any step, it can't work.

success……"

Li Shimin thought thoughtfully, nodded and said: "A giant waterwheel is set up in the river to draw water into the ditch. However, there is a prerequisite for this, and that is that there are ditches in the fields."

Duan Lun did not hesitate and said directly: "So digging the trench is the first step of this project." [The word "project" existed in ancient times]

Li Shimin pondered for a moment and then added hesitantly: "This kind of equipment can only be installed after the ditch is dug. But there is a prerequisite for this, that is, this kind of equipment must be manufactured in large quantities first. If it is not possible to manufacture it, you must have a large number of installations.

personnel, so that they can rush to all directions and install this thing in trenches dug all over the world."

After being awakened, the officials soon joined the analysis team.

Someone said: "Just installing it is not enough, you have to teach the people to use it. We can only see this device constantly pumping water, but there are times when any field does not need water, so there must be a way to control this device to stop it."

"

Another person said: "After doing all this, you still need to pay attention to maintaining this thing, otherwise it will break down after a year or two. Should you continue to send people to various places to install it again? That would be too costly, and it will definitely outweigh the gain."

Amidst the divergent opinions, a huge system project was gradually elaborated.

Then everyone looked weird.

At this time, they finally understood why Gu Tianya didn't care and asked his disciples to show everyone this thing.

Because this project is simply not an industry that one company can monopolize.

Li Shimin laughed and suddenly looked in the direction of Miyun County, Tanzhou. After a long time, he said with deep meaning: "So this is your purpose."

Since ancient times, the biggest motivation is to lure people with benefits. The huge benefits are right in front of you. I wonder if you are tempted or not.

Previously, everyone only talked about the increase in land production for the people, which was enough to make the entire Tang Dynasty dominate the world, but everyone knows that this talk is just a high-sounding statement.

The real big benefit is that each household's pockets will be bulging.

How much land do people have in their hands?

One family only has four to five hundred acres.

However, among the officials present, the family farmland is not comparable to that of ordinary people. Let’s not talk about the aristocratic families that have been passed down from generation to generation, let’s talk about the newly rising families in Tiance Mansion. Which family does not own thousands of acres of land? Some of them have thousands of acres of land.

The family even owns 30,000 to 40,000 acres.

If everyone can increase their grain production by more than fifty kilograms, how many years will it take for them to become a wealthy family?

This alone is enough to make everyone face Gu Tianya with a smile on his face. If a smile on his face is not enough to show his goodwill, then he has to bow down to gain friendship.

The benefits are too great.

Just at this moment, I suddenly heard a distant voice, saying calmly: "My master said that water conservancy projects are only the foundation. When dry fields are turned into paddy fields, it can indeed increase food production slightly. However, the inherent crop yield is too low.

Okay. If you work hard for an acre of land for a year, you can only harvest a few dozen kilograms of grain at most. This is not called harvest, it is called waste. Therefore, my master believes that the field yield must be at least seven or eight dan to be worthy of it.

The hard work of the people of the Tang Dynasty..."

The whole place was silent.

Everyone was trembling.

This trembling is not due to cold, because it is only the Mid-Autumn Festival, and this trembling is not due to fear. No one in the world can make this group of people afraid together.

This trembling was entirely due to shock, and this trembling was entirely due to excitement, just because they all heard one word clearly just now, Gu Tianya's apprentice said that the production field can have seven or eight stones.

If someone else said this, everyone would definitely slap him in the face, and after a beating, they would immediately say "wishful thinking".

But the person who said this was none other than Gu Tianya's female apprentice.

The words were not finished. The female apprentice was still holding something in her hand and said quietly: "This thing is called sweet potato. My master said that its field yield of seven or eight dan is considered small. If the people take good care of this crop,

, one acre of land can even produce fifteen or even twenty stones."

There was a thud and someone fell to the ground.

Everyone looked around and saw that the fallen man had squinting eyes, his eyes seemed to be demented, and his mouth was filled with irritating words. It turned out to be Duan Lun, Minister of the Ministry of Industry. The fat man was trembling at this time and kept talking.

: "Fifteen stones, twenty stones? Fifteen stones, twenty stones..."

No one despises his appearance, but everyone thinks it should be so.

The yield of fifteen shi per acre of land, or even the yield of 20 shi, is simply a myth. No one can remain calm after hearing this.

What is the yield per acre today?

The best Tianzihao irrigated land only has about one stone.
