Li Er asked the student to get up, and Gao Buer saw that the student was frightened by Li Er's domineering spirit, and immediately stepped forward and said: "Your Majesty, what this student said is right, by trying to plant the cultivated seeds in the field, the yield has indeed increased a lot, and the farmers near Yangzhou have been planting the seeds of the first two generations. ”

"I'm really an eye-opener, Uncle Huang, aren't the seeds cultivated like this very expensive?"

"On the contrary, it is lower than the cost of keeping the seeds themselves?"

"Why is that?" Li Er wondered, in his philosophy, the better the thing, the more expensive it is.

"Because our seeds are grown in the laboratory and then planted in large experimental plots, the harvest will increase, the harvest will increase, and there will be a profit from selling it at the market price, and we can sell the improved seed as long as we don't lose money, so we divide this part of the profit into the seeds, so that the price of the seeds can be sold to the growers at a price lower than the market price. Moreover, the seeds produced in the laboratory are produced on an assembly line, which can be produced regardless of the season, and the cost itself is low. ”

Li Er didn't care if he understood it or not, he just nodded, anyway, the academy wouldn't lose money, farmers could also save some money, and they could make a lot of money if they planted good seeds to increase their income, so why not do such a good thing?

So Li Er hurriedly asked: "Can this technology be promoted on a large scale?" ”

Gao Buer heard him ask, his heart was overjoyed, just waiting for you, like this kind of public welfare can not be promoted nationwide without the imperial court in charge, Gao Buer said: "Of course you can, and this law is very easy to promote, if you can get your Majesty's support, I believe that it will not take four or five years to build such a breeding base in every state, so that the overall grain output of the country can go up." ”

"That's good, then I also ask Uncle Huang to select a batch of all the talents in this process, and I will bring them back to Chang'an and start to promote them."

Gao Buer nodded in agreement and instructed Xu Jingzong to prepare.

Then Li Er visited the new agricultural tool exhibition room, the shipyard and the distillery production line, and then came to the steam engine research and development laboratory.

Li Er stood next to the latest generation, almost two meters high, and circled around the steam engine, Li Er asked, "This steam engine may be used to cultivate land now?" ”

Gao Buer said: "Back to Your Majesty, the prototype of the tractor has been made at present, and it has been assembled last night. ”

Li Er's eyes shone and said, "How long does it take to assemble?" ”

"An hour is enough."

"Then what are you waiting for, please Uncle Huang arrange it immediately, I can't wait to see how this guy who doesn't need the power of livestock plows the land."

Gao Buer was waiting for Li Er to endorse his tractor, of course, he readily agreed, under the command of Xu Jingzong, a flat-like tractor was pushed in by a group of students, and then the simple tower crane began to work, looking at the busy crowd, working in an orderly manner.

Li Er said: "Uncle Huang, no wonder you respect this assembly line operation so much, and now it seems that it has indeed improved a lot of efficiency, it is really great wisdom." ”

Du Ruhui also echoed: "What Your Majesty said is extremely true, whether it is tools or craftsmanship from the hands of Uncle Huang, it will be of great help to promote social progress, so the prosperity of my Tang Dynasty can be expected in the future." ”

Gao Buer said modestly: "Thank you, Your Majesty, Du Xiang, in fact, this is all the credit of the academy, I gave them a direction, who knew that there is such a scale now, of course, the biggest reason for this is Your Majesty's Sacred Heart, otherwise Xinxue will not have a foothold, let alone show it in the world." ”

"As long as it is beneficial to the country, the prosperity of the country can not only rely on the strength of the soldiers, but should be in all aspects, now this way, especially to see the prosperity of Yangzhou industry, it is really comforting, I don't know what the financial department said the emperor will look like."

"Your Majesty, the minister has asked Wang Yuanbao to prepare, and after reading it, Your Majesty will be able to see a complete theory of the financial system."

"Okay, I'm really looking forward to the scene that Uncle Huang said that the country does not raise taxes and the country uses enough, since the founding of the Tang Dynasty, the country has been fighting for many years, and the country is always stretched."

Gao Fuji nodded.

Xu Jingzong walked up to the front and said: "Your Majesty, the steam engine has been assembled, and the selected test site is outside here, please ask Your Majesty and all the adults to wait outside for a while, because of the air tightness problem, the water vapor produced by the steam engine is relatively large, and people in the room are easy to be wet by the steam." ”

Li Er nodded, and walked outside with the civil and military officials.

Gao Buer, who deliberately lagged behind, asked Xu Jingzong: "Have you tried this tractor prototype, don't be the first shot when the first shot doesn't go off, and it will be even more difficult to promote it later." ”

"Lord Wang, please rest assured, the things that have not been tested by the lower officials will not dare to be brought to His Majesty."

Gao Buer nodded and quickly caught up with Li Er, and when everyone arrived at the viewing platform prepared by the academy, they saw the water vapor in the room just now.

Gao Fuji explained: "Your Majesty, these are all water vapor and harmless to the human body, because the sealing problem caused most of the water vapor to leak out, and the energy has also lost about forty percent. ”

Li Er nodded.

At this time, there was more water vapor gushing out of the room, and soon a behemoth was seen slowly running out of the smoke, and when the smoke cleared a little, everyone saw that the thing they had just seen was moving on its own.

The students of the academy had already operated dozens of experiments before, and at this time, the steady control machine began to plow in the pre-prepared land, and when the half acre of land was plowed, they changed to a special rake and ploughed it again, and after finishing it, Gao Fuji asked Li Er to wait in the field to see the effect.

The official with good deeds found a hoe, dug up the turned ground, and said in amazement: "This thing can really replace the ploughing ox, the plough is more than ten centimeters deep and effortless, the key is that this thing can be cultivated without rest, as long as the person is replaced, this thing is really wonderful." ”

Li Er was also surprised: "Uncle Huang, do you say that this can really be cheaper than ploughing cattle?" ”

"Yes, Your Majesty, now that the academy has found iron ore in the south, and the academy's iron-smelting process is constantly improving, this thing is simply a steam engine running on four wheels, nothing unusual, so the price is no higher than a cow." The words of the car maniac in later generations were plagiarized by Gao Fuji again, and now he doesn't know how many things he has plagiarized in later generations, and he estimates that he himself can't figure it out with his fingers.

Du Ruhui said: "Uncle Huang, can this thing really burn firewood and run?" "What's so much in Datang now? There are many barren mountains and of course, and of course, there is also a lot of firewood, so much so that anyone can afford to burn it.

Gao Fuji gave him an affirmative answer: "Of course you can, if you don't pursue speed, it's absolutely no problem to burn firewood and plough the land." ”

"I really hope this thing can be mass-produced soon." Li Er sighed, the people of Datang must be industrious, but due to the lack of cattle, many wastelands can not be developed, this tractor is the artifact he needs, he dreams of making Datang no longer have hunger, now there are good seeds, high-yield grain is also available, what is lacking is ploughing cattle, ah no, what is missing is what is called a tractor in front of him.
