My short video leads to ancient times, and the ancients break the defense!

Datang, Xuanzong plane.

"Yao Chong, what is the rice yield of our Datang?".

Tang Xuanzong looked a little tired, he accompanied Yang Guifei every day these days, and his body was a little unbearable.

Looking at the multiple-choice questions in the sky, Tang Xuanzong became interested in his current grain production in the Tang Dynasty.

"Your Majesty, the highest grain output in our Datang is in the Huainan generation, where basically every mu of land can produce about three stones of grain. "

Yao Chong was the minister of Tang Xuanzong, and half of the appearance of the prosperous era of Kaiyuan was due to the credit of this old minister.

"Three stones, that converted into catties and taels, how many catties is approximately?"

"It's only about a hundred pounds. "

Hearing this answer, Tang Xuanzong frowned, obviously very dissatisfied with this answer.

"Why is there only so little?".

"I look at what is shown on the light and shadow, and the minimum is five hundred catties, which is more than five times that of us. "

"This is not necessarily the true yield of hybrid rice. "

"Is it because our people in Datang are not industrious enough, which leads to such a low grain output?"

Yao Chong shook his head and said

"Your Majesty, the people of my Tang Dynasty are the most diligent in the world. "

"It's just that later generations have carried out special treatment of rice, which has greatly increased the yield of rice. "

"If I can get these rices in Datang, then the people of the world will really have no worries about food and clothing. "

Tang Xuanzong nodded slightly, and was about to say something, when suddenly a light curtain appeared in front of him, and it was the selection panel.

"It's... What is this?".

Tang Xuanzong was taken aback by this sudden scene and screamed.

Gao Lishi beside him hurriedly came to Tang Xuanzong and asked anxiously

"Your Majesty, what happened?".

The Minister of Civil and Military Affairs was also surprised to look at Tang Xuanzong.

Fortunately, after a brief shock, Tang Xuanzong slowly recovered and realized that this might be the means of the immortals.

It's just that in the face of this kind of selection panel, Tang Xuanzong couldn't make up his mind for a while, and he didn't know which one to choose.

"I'm fine. "

Tang Xuanzong showed that he appeased the ministers of the court, and then asked Yao Chong again

"Yao Chong, how many catties do you think the rice yield per mu in later generations can reach?"

Yao Chong thought about it and said with some uncertainty

"Although there have been earth-shattering changes in later generations, food will eventually grow from the ground, and hybrid rice is still rice, as long as it is rice, it will be limited by grains. "

"I think that all kinds of factors are superimposed, and the rice yield in later generations will be at most ten times our current output, that is, 1,000 catties. "

Tang Xuanzong felt reasonable, but he didn't choose it immediately, but looked at the big fat man at the bottom and asked:

"Lu'er, what do you say?"

This big fat man is An Lushan, and he often calls Tang Xuanzong and Yang Guifei the miscellaneous beards of godfather and godmother.

When An Lushan heard this, he immediately showed a flattering smile and said:

"I'm just a rough man, and I'm a mess about farming, and my godfather asked me about it, but it was really embarrassing for me. "

said, and showed a look of grievance.

"Hahaha, you, you should go to the field and have a good experience!"

Tang Xuanzong was amused and laughed.

As he spoke, Tang Xuanzong chose the second option on the selection panel in front of him.

[If you answer incorrectly, you will be deducted from your life span for ten years.] 】

Tang Xuanzong, who was still smiling, suddenly turned red, and a mouthful of reverse blood gushed out of his chest, and then... Poof!!

Bright red blood sprayed all over An Lushan's face, but he didn't bother to wipe it, but instead shouted in horror

"Godfather !!

".

"Godfather, are you okay? Godfather??!

".

Seeing that Tang Xuanzong suddenly vomited a mouthful of blood, the civil and military officials instantly panicked.

Li Tang's emperor, there are not a few who died violently, and now Tang Xuanzong's face looks like a dead man, how can he not be frightened?

"None... Anyway. "

Tang Xuanzong screamed weakly, then supported himself with his right hand, leaned down on the dragon chair, and said

:

"Fuzhen... Back to the palace, I need... Rest. "

Gao Lishi hurriedly helped Tang Xuanzong to walk to the harem, leaving the Minister of Civil and Military Affairs with a confused face.

...

Above the light and shadow, the video starts playing.

[There are many staple foods of the Chinese people, which can be roughly divided into wheat, rice, potatoes, corn, and sweet potatoes. 】

[Among them, wheat and rice are the grains that the Chinese nation has eaten since ancient times, and they have a long history in China. 】

[Sweet potatoes originated in the Americas, but in the middle and late Ming Dynasty, they were introduced to China by Luzon, and this kind of sweet and satiety grain first began to be planted in the coastal areas of Fujian Province, and then gradually accepted by the Chinese people. 】

[Sweet potato is drought-resistant, extremely adaptable, and more importantly, this grain is a high-yield grain, with an average production capacity of about 1,000 catties per mu. 】

[Corn and potatoes are also produced in the Americas, and the yield of potatoes and corn is more exaggerated than that of sweet potatoes.] 】

[In the case of dense planting, the yield of corn and potatoes can reach 1,500 catties per mu, which is a very high-yield crop. 】

[The drought resistance of potatoes and corn is stronger than that of sweet potatoes, in addition to drought resistance, they are also very cold-resistant, so potatoes and corn can even be planted in the desert grassland and the bitter cold areas of eastern Liaoning. 】

[These two grains were introduced to China during the Qing Dynasty. 】

[In the middle and late Qing Dynasty, the population of China could reach 40,000,000, and the contribution of sweet potatoes, corn and potatoes was indelible. 】

.......

Great Han, Han Wu plane.

"With a grain yield of 1,500 catties per mu, is there really such grain in this world?"

After Liu Che saw the introduction of corn, sweet potatoes and potatoes, he was not calm for a moment, and his whole person suddenly rose, staring at the light and shadow with wide eyes, as if he wanted to stare down the grain in the light and shadow.

"Is this the grain seed that should exist in the world? This is clearly an immortal seed!!".

"If the people of my Han can have these kinds of grain, how strong will my Han be?"

"The Americas... Americas.... Where is America? If I want to find there, I must get these grains!"

Liu Che's whole mood is unusually high, as an eloquent emperor, he deeply understands that the foundation of the country's strength is the strength of the people at the bottom.

The strength of the people lies in food, clothing, shelter and transportation, of which food is the most critical link.

As long as the people can keep their stomachs full, the big man's taxes, money and food will be endless, and there will be no worries about the people rebelling.

As the master of the empire, he can use this money and food to do more of the great things he wants to accomplish.

Emperor Wu of the Han Dynasty was very excited, and Wei Qing on the side was even more excited than Emperor Wu of the Han Dynasty

"Your Majesty, that potato, we big men must get it!!".

"That's the key to our complete subjugation of the Huns, as long as we get the potatoes, the Huns will be completely exterminated by my Han!"
