I make a popular science video and all the emperors learn from it!

Kangxi ordered his eunuch to pick up the books on the ground.

Holding it in front of him, he opened it and started reading.

Not a moment.

He lost interest.

After handing the book to several internal ministers, he stopped asking any more questions.

Until a few days later.

Kangxi ate the dishes cooked by the imperial dining room as usual.

Only today is different.

I saw the eunuch bringing a plate of dark things.

No one has arrived yet.

Kangxi smelled an indescribable stench

"Your Majesty, this dish is newly added today. It was recorded in the book obtained from the sky light curtain a few days ago."

"Don't look at it, it smells very bad, this smell......"

The eunuch hasn't finished praising you yet

"vomit......"Kangxi had already vomited out,"Get out of here! Take the things away!"

In just a short while.

He almost vomited out his liver juice, and the eunuch was so frightened that he immediately removed the thing.

Kangxi was in no mood to eat.

He stared angrily at the light curtain.

Knew it!

He thought he got something good, but it turned out to be disgusting to him, right?! ?

Very good, I was successfully angered!....................................

【The ten crops with the greatest scientific contribution to mankind!】

【Fifth place: sweet potato】

【Sweet potato is a perennial herbaceous vine of the genus Tiger Palm in the Convolvulaceae family.】

【Characteristics: Milky, with white, red or yellow roots; stems with adventitious roots; broad oval or oval heart-shaped leaves, with leaf colors ranging from dark green, yellow-green, purple-green, etc., with a tapered front end and a heart-shaped or ** shape at the base. Cut; the corolla is pink, white, lavender or purple, bell-shaped or funnel-shaped, hairless; the chrysanthemum fruit is oval or oblate; because sweet potatoes are cross-pollinated, self-pollination often does not produce fruit, so sometimes Only flowers but no fruits】

【Sweet potato is a high-yielding and adaptable food crop】

【It is closely related to industrial and agricultural production and people's lives; in addition to being used as a staple food, it is also an important raw material for food processing, starch and alcohol manufacturing industries.】

【Roots, stems and leaves can be used as excellent feed】

【Its yield per mu is very high, tens of stones per mu, which is twenty times better than growing grain.】

【...】

Qin Dynasty.

Ying Zheng looked at the video played on the light screen, with the accompanying text explanation, and fell into a long silence. this... how can that be possible?

Are sweet potatoes really as good as they say?

Not only is the yield per mu twenty times greater than that of millet, its roots, stems, and leaves can also be used as feed!

Impossible, absolutely impossible.

Ying Zheng suddenly had doubts about life.

The millet in his hand suddenly lost its fragrance.

Compared with sweet potatoes, the yield of this thing is pitifully low.

"Li Si, please explain to me, is what this light curtain says possible?"

Ying Zheng needed someone urgently to tell him that it was a lie.

At this time, Li Si's mouth was wide open and his eyes were full of horror. He heard the summons.

He tried hard to suppress his expression.

"Returning to Your Majesty, I also thought it was a fantasy, but what Guangmu said was basically true. Maybe this kind of food really does exist in the world."

"Your Majesty must try his best to fight for it."

The magical method of the light curtain has been verified. Even if they want to refute, they can't find evidence.

Ying Zheng didn't say anything after hearing this.

He had long regarded this kind of food as the staple food of the Qin Dynasty!

Han Dynasty.

Liu Bang got up and walked around the hall..As crops become more popular in science, their role becomes more important to a country.

"Twenty times more than grain..."

"A full twenty times."

If the yield of sweet potatoes was only several times that of grains, he could still remain calm.

Liu Bang stopped, looked at the many ministers in the audience, and shouted:"Everyone, you must help me obtain this crop!"

He couldn't imagine.

If the Han Dynasty could obtain this crop, how many times could the country's population increase!?

If the Han Dynasty really got sweet potatoes, he might also become a wise king in the mouths of future generations.

Xiao He in the audience took a step forward , solemnly said:"I will do my best to assist Your Majesty!

Fan Kuai shouted with a smile:"Your Majesty, we will definitely do our best.""

Even Han Xin, who has always been proud, jumped out and echoed......

Shu Kingdom.

Liu Chan stared blankly at the light curtain.

But Zhuge Liang had already pulled his sleeves at some point, his eyes full of longing for sweet potatoes.

‘I understand, don’t worry, Xiangfu. '

Liu Chan knew it was time to take action!

Just like the previous time, there is a Q&A session, so you can choose blindly.

If he is right, his father-in-law will definitely be impressed by him.

Tang Dynasty.

Changsun Wuji, Fang Xuanling and others knelt down and shouted:

"Your Majesty, this kind of divine food will definitely make the Tang Dynasty more prosperous!"

"By then, we, the Tang Dynasty, will not need to use the means of marriage to make concessions to the grassland people!"

Cheng Yaojin clenched his fists excitedly.

If he could increase the Tang Dynasty's grain output several times, he would be able to lead more soldiers.

With heavy troops in hand, there would be no need to worry about the invasion of the prairie people!

There is no need to use marriage methods to stabilize the situation. live them

"Damn prairie people, your grandfather Cheng Yaojin will lead an army of hundreds of thousands to your door. Let’s see how arrogant you are!"

Li Shimin's chest heaved violently.

He had sacrificed too much for the prosperity of the Tang Dynasty and lost a lot.

Marriage was a scar in his heart.

A huge country actually needed marriage to protect its border security.

When he married his daughter to the grassland, he I feel bad too..................................

Song.

Zhao Kuangyin was surprised again and again

"Sweet potato?"

"The yield per acre of this thing is so high!"

"I don’t know if there is any fate with me......."

He was manipulated several times by the light curtain and became Buddhist-like in his heart.

If you can get it, keep it. If you can't get it, don't be disappointed.

Take it easy.

Otherwise, he is worried that his mood will be influenced by the light screen all the time, and his life will be short-lived easily.

Ming Dynasty.

Zhu Yuanzhang is completely crazy!

Looking at the light curtain, he shouted excitedly:

"We are lay people and we like food with high yield!"
