The emergence of new crops directly made the voices of the DPRK and China oppose "grain ***" disappear in an instant, and all provinces have also seen the possibility of completing the threefold increase in annual grain output under the method of replacing the new crops with one to three.

The counties below the province have no time to complain, because they have to rush to the province to fight for the qualification of the new crop cultivation area.

Only by allowing the counties under his rule to win the qualifications of new crop cultivation areas can we better ensure the increase in total grain output this year.

The improvement of the plough is also under the promotion of the Ministry of Industry, and it is rapidly popularized throughout the country.

Li Yang's improved plough has greatly improved the efficiency of cultivated land.

The plough in the Qin Dynasty was a straight plow.

The characteristic of the straight plough is a triangular bronze ploughshare, with a handrail of wood on it, and the plow is at a right angle of 90 degrees to the handrail.

How to describe it, it is similar to a hoe standing on the ground. It was only the oxen that pulled the upright hoe forward. This kind of straight plough is obviously inconvenient for ploughing the field.

And Li Yang first changed the straight and long wheels to curved wheels and short wheels, and installed a plow plate that can rotate freely at the head of the wheel, which not only makes the plow frame smaller and lighter, but also easy to turn around and turn, and the operation is flexible, saving manpower and livestock. And this kind of plow, in fact, is the later Ming and Qing dynasties, has been used until the liberation of the Quyuan plow.

The plough is very simple to build, by the Shaofu one day according to Li Yang's drawings to make out, and then the improved samples will be distributed to the provinces, the blacksmiths and carpenters of the provinces will see it, so the popularization is very rapid.

Under the impetus of the policy, the support of the imperial court and the local government, the improvement of labor tools, and the land reform policy of equal distribution of land to households, the enthusiasm of the people has reached an unprecedented high, and the national cultivation and production industry has become a scene in full swing. The whole country is doing it vigorously.

Driven by the efforts of the whole country, by the end of spring, all the paddy fields in Daqin had been planted with rice, and the dry land had been planted with wheat chestnuts, as well as new crops brought by Shaohao.

The area under cultivation in the whole country has also more than tripled compared with the years when forced labor was heavier.

…………

After more than a month, although Li Yang still supervised the farming affairs, the grain chestnuts and new crops were basically planted, and he completely handed over the farming affairs to the household department to be responsible.

And Fusu seems to be even more fine, anyway, this year's grain production increase has basically become a foregone conclusion, which is already a great achievement for him during his time in charge of the country after his father left.

Just imagine, within a year, Daqin's grain production has tripled, what a proud thing.

So Fusu simply ignored all the affairs of the DPRK and China, and devoted himself to the Academy of Engineering, and studied Daqin's new inventions with Zhang Cang - hot air balloons and human-powered airships.

Because before Ying Zheng left, he had already set the direction of Daqin's development in the future.

First, the development of agriculture.

The second is the development of handicrafts and commerce.

The third is the development of the sea and air fields.

Originally, Fusu was going to go to Jiangzuofu to study explosives, but he was forbidden by Li Yang, and if there was an explosion, it would be terrible to blow up the future prince of Great Qin.

So, in the end, Fusu had to study hot air balloons and human-powered airships.

For Fusu, hot air balloons and human-powered airships are also of great interest. Because in Li Yang's description, these things can carry people and travel in the sky, and that scene is really reverie.

Regarding Fusu's nonsense, Li Yang was happy to let him find something to do, after all, if nothing else, he was the future monarch. A future monarch has a strong interest and understanding of science and technology, and has a significant impact on the future direction of Great Qin.

Thinking about it this way, Li Yang was very relieved to be in charge of the court alone and made every effort to promote the implementation of the new policy.

Actually, Li Yang is also very busy.

In the spring, the farming has just been completed, and in the summer, Li Yang has to worry about natural disasters such as floods, and he also wants to inspect the growth of new crops.

In addition to patrolling, the construction of sea vessels is also particularly important.

This is not only about the sea exchanges between Shaohao and Daqin, but also about the safety of Yingzheng.

If there were not enough sea ships, Ying Zheng would be in danger in Shaohao, and Daqin's army would not be able to send rescue. Therefore, the construction of sea ships is also imminent.

On this morning, because the emperor was not there, there was no need to go to court early, so Li Yang would basically sleep until the hour before getting up.

As usual, Li Yang hugged Yangzi with his left hand and Natasha with his right hand, and slept very contently.

In his opinion, going home and sleeping is the happiest thing in the world.

"Taifu...... Taifu ......"

He was sleeping soundly when suddenly an eerie voice seemed to appear in his room.

"Taifu...... Taifu ...... Wake up......"

Li Yang was a little confused, why does this sound so much like Fusu's voice?

What the hell, how could Fusu come to his room.

Li Yang was too sleepy because of his recent fatigue, so he didn't care about the call, and directly hugged the two girls into his arms, planning to sleep beautifully for a while.

"Taifu, Taifu......"

The call was still there, and some people were pushing themselves with their hands, and they were lifting their own quilts.

Li Yang suddenly realized that this was not a fucking dream, it was really someone calling himself by his bedside.

Quickly opened his eyes and saw that his uncle, Fusu really appeared in his room, and a pair of eyes were still admiring Natasha who was hugged in Li Yang's arms and was only wearing a tulle.

Li Yang's mood is a dog.

Where would someone sneak into someone else's room, and he would lift the quilt to see it knowing that there were two women sleeping on the bed?

Fuck, isn't this a pervert spirit!

Li Yang hurriedly grabbed the quilt, stared at Fusu with a vigilant expression, and asked, "Your Highness, what are you...... What do you want to do? ”

Natasha's wonderful body was covered by the quilt again, and Fusu finally took his eyes back, and said excitedly: "Airship, airship is done, we finally invented the airship." ”

"You ran to my room early in the morning and told me this?"

When Li Yang heard this, his face was black.

Fusu nodded, seeing Li Yang's expressionless appearance, he couldn't help but be curious: "Taifu, we will be able to take an airship to swim in the air soon, aren't you excited, aren't you excited." ”

Li Yang thought to himself, Lao Tzu is a person who has ever done an airplane, what can a hot air balloon be excited about.

Let alone...... This so-called airship has just been invented, and it is not certain whether it can carry people into the sky. Moreover, even if it can really carry people into the air, then its safety is also a big problem, what if it rises into the air and falls?

However, it is still worth affirming that they can make airships so quickly under their own orders.

Therefore, Li Yang immediately greatly appreciated Fusu: "His Royal Highness's invention of the airship hot air balloon, so that the dream of human beings to fly is one step closer, this is a strong stroke in the history of human development, you take a small step forward, is a big step in the development of human science and technology, but also laid the foundation for the future aviation field, and His Royal Highness can also be regarded as the father of the aerospace field, His Royal Highness's name will be recorded in history, so that future generations will admire." ”

Sure enough, when Fusu heard Li Yang's praise, the whole person grinned.

Seeing that the child was smiling like a monkey, Li Yang waved his hand: "Okay, you can go back first." ”

Fusu shook his head: "Lone doesn't go back, Lone is here to invite Taifu to take an airship test flight and travel the sky." ”

When Li Yang heard this, he almost didn't fall from the bed to the ground.

"What do you say? Try...... Test flight! ”

Li Yang was afraid that he had heard it wrong.

"Exactly, Zhang Cang is waiting for us in the Engineering Institute, Taifu, let's hurry over." Fusu looked like he couldn't wait to send Li Yang to the sky, and while urging, he came to pull Li Yang.

Li Yang was stupid.

Test flight?

I'll test fly your sister! Such an unsafe thing, you told me to be the first to go to a test flight? Your uncle, don't you want Lao Tzu to die!

Li Yang shook his head immediately: "You...... You let it go, this airship has just been developed, and there must still be many deficiencies, how can you just take a test flight, it's too unsafe. ”

Fusu was in the midst of excitement, where would he listen, and said hurriedly: "It's already very successful, there are no shortcomings." Taifu rest assured, Gu and Zhang Cang will take a test flight with you. ”

"If you want to fly, this hospital will never go to test flight with you!"

Such a stupid thing, Li Yang would not agree to it if he was killed. In his opinion, this is tantamount to risking his own life, and if this kind of stupidity is also agreed, what is the difference between it and being stupid?
