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

Tang Dynasty, Xuanzong plane

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

Tang Xuanzong looked a little tired. He had been accompanying Concubine Yang every night these days, and his body was a little overwhelmed.

Looking at the multiple-choice questions in the sky, Tang Xuanzong became interested in the current food output of his country.

"Your Majesty, the current grain output in our Datang Dynasty is the highest in Huainan, where basically every acre of land can produce about three shi of grain."

Yao Chong was the humerus minister of Emperor Xuanzong of the Tang Dynasty. The emergence of the prosperous Kaiyuan era was partly due to this veteran minister.

"Three stones? Then converted into kilograms, how many kilograms is it?"

"Only about a hundred pounds."

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

"Why is there only so much?"

"I see that the light and shadow show that the minimum weight is five hundred pounds, which is more than five times that of ours."

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

"Is it because the people of Tang Dynasty are not hardworking enough that the food output is so low? Yao

Chong shook his head and said:

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

"It's just that later generations performed special treatments on rice, which greatly increased rice production."

"If we, the Tang Dynasty, could get this rice, the people of that world would really have no worries about food and clothing."

Tang Xuanzong nodded slightly and was about to say something else. Suddenly, a light curtain appeared in front of him. It was the selection panel.

"this...What is this? Tang

Xuanzong was startled by this sudden scene and screamed.

Gao Lishi, who was beside him, hurriedly came to Tang Xuanzong and asked anxiously:

"Your Majesty, what happened?"

The Minister of Civil and Military Affairs also looked at Tang Xuanzong in surprise.

Fortunately, after a brief shock, Tang Xuanzong slowly recovered and realized that this might be the immortal's method.

But faced with this choice panel, Tang Xuanzong I can't make up my mind at the moment, I don't know which one to choose.

"I'm fine."

Tang Xuanzong appeared to appease the officials in the court, and then asked Yao Chong:

"Yao Chong, how many kilograms per mu do you think rice can achieve in future generations? Yao

Chong thought for a while and said with some uncertainty:

"Although earth-shaking changes have taken place 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 to grains."

"I believe that due to the combination of various factors, the rice yield in later generations will be at most ten times our current yield, which is one thousand kilograms."

Tang Xuanzong thought it was reasonable, but he did not choose immediately. Instead, he looked at the big fat man below and asked:

"Lu'er, what do you think?"

This big fat man is obviously An Lushan. He often calls Tang Xuanzong and Yang Guifei his godfather and godmother.

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

"I'm just a rough guy, and I don't know anything about farming. My godfather asked me about this, which really made things difficult for me."

As he said this, he looked aggrieved.

"Hahaha, you should go to the fields and practice hard!"

Tang Xuanzong was amused and laughed.

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

【If the answer is wrong, ten years of life will be deducted. 】

Tang Xuanzong, who was originally smiling, suddenly turned red, and a mouthful of blood poured out of his chest, and then...puff!!!

Bright red blood spurted all over An Lushan's face, but he didn't bother to wipe it off. Instead, he shouted with horror on his face:

"Godfather!!!"

"Godfather, are you okay? Godfather? ?!"

Seeing Tang Xuanzong suddenly vomiting a large mouthful of blood, the civil and military officials immediately panicked.

Many emperors of Li Tang died suddenly. Now Tang Xuanzong's face looks like a dead man. How can we not make people afraid?

"none...No problem."

Tang Xuanzong gave a weak cry, then used his right hand to support his body, leaned on the dragon chair, and said:

"Help me...Return to the palace, I need it...rest."

Gao Lishi hurriedly helped Tang Xuanzong walk to the harem, leaving the civil and military ministers confused....

Above the light and shadow, the video starts playing

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

【Among them, wheat and rice have been eaten by the Chinese people since ancient times and have a long history in China.】

【The origin of sweet potato is in America, but it was introduced to China from Luzon in the middle and late Ming Dynasty. This sweet and very filling food was first planted in the coastal areas of Fujian Province, and then gradually became accepted by the Chinese people.】

【Sweet potatoes are drought-resistant and highly adaptable. More importantly, this kind of grain is a high-yielding grain, with an average yield per mu of about 1,000 kilograms.】

【Corn and potatoes are both foods produced in the Americas. Compared with sweet potatoes, the yields of potatoes and corn are even more exaggerated.】

【When planted closely, the yield of corn and potatoes can reach 1,500 kilograms per acre, making them very high-yielding crops.】

【The drought resistance of potatoes and corn is even stronger than that of sweet potatoes. In addition to drought resistance, they are also very cold-resistant. Therefore, potatoes and corn can even be planted in the Mobei grassland and the bitter cold areas of Liaodong.】

【These two kinds of food were introduced to China during the Qing Dynasty.】

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

Dahan, Hanwu plane

"An acre yields 1,500 kilograms of grain. Is this kind of grain really available in this world?"

After Liu Che saw the introduction of corn, sweet potatoes and potatoes, he immediately lost his composure. He suddenly stood up and looked at the light and shadow with wide eyes, as if he wanted to stare down the food in the light and shadow.

"Is this the type of food that humans should have? This is clearly an immortal seed!!"

"If our Han people could have these grains, how powerful would our Han people be?"

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

Liu Che's mood was extremely high. As a talented emperor, he deeply understood that the foundation of a country's strength is the strength of the people at the bottom. The strength of the people lies in their food, clothing, housing and transportation, of which food is the most critical part..

As long as the people can always fill their stomachs, the big man's taxes, money and food will be a constant source of energy, and there will be no worries about people's rebellion.

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

Emperor Wu of the Han Dynasty was extremely excited. Wei Qing on the side was even more excited than Emperor Wu of the Han Dynasty:

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

"That is the key to our ability to completely conquer the Huns. As long as we get the potatoes, the Huns will be completely wiped out by my big man!"
