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

Kangxi ordered the eunuch with him to pick up the books on the ground.

In front of him, he opened it and began to read.

Not for a while.

He lost interest.

After handing over the book to several ministers of the court, he did not bother with it anymore.

Until a few days later.

Kangxi usually eats the dishes made in the imperial dining room as usual.

It's just that today it's different.

And he saw the eunuch bring a plate of black things.

People haven't arrived yet.

Kangxi smelled an indescribable stench.

"Your Majesty, this dish is new today, and it is recorded in a book obtained from the sky light curtain a few days ago. "

"Don't look at it, it smells so bad, it smells ......."

The eunuch hasn't finished praising yet.

"Vomit ......" Kangxi had already spit out, "Get out! Take things away!".

Just a short time.

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

Kangxi was so confused that he was in no mood to eat.

He stared angrily at the light curtain.

Sure enough!

He thought he was getting something good, and it turned out to be disgusting to him, right!?

Very well, I was!

....................................

[The ten crops that have made the greatest contribution to mankind in popular science!].

[Fifth place: sweet potato.] 】

[Sweet potato is a perennial herbaceous vine of the family Tiger Palm Vine. 】

[Characteristics: with milk, the root is white, red or yellow; the stem is adventitious; the leaves are broadly ovate or ovate heart-shaped, the leaf color is dark green, yellow-green, purple-green, etc., the front end is acute, and the base is heart-shaped or **truncated; the corolla is pink, white, light purple or purple, bell-shaped or funnel-shaped, glabrous; chrysanthemum fruit is ovate or oblate; because sweet potato is cross-pollinated, self-pollination often does not bear fruit, so sometimes only flowering does not bear fruit. 】

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, dozens of stones per acre, and 20 times better than the valley. 】

【...】

Qin Dynasty.

Ying Zheng looked at the video playing in the light curtain, with a text explanation, and fell into a long silence for a while.

This....

How is that possible?

Are sweet potatoes really as well said?

Not only is the yield per mu better than that of millet 20 times, but its roots, stems, and leaves can also be used as fodder!

Impossible, absolutely impossible.

Ying Zheng suddenly had some doubts about life.

The millet in his hand suddenly stopped smelling.

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

"Li Si, you can explain to the widow, is it possible for this light curtain to say?"

Yingzheng urgently needs someone to tell himself that it is fake.

And Li Si was opening his mouth wide at this time, his eyes full of horror.

Hear the summons.

He struggled to suppress his expression.

"Back to Your Majesty, the minister also thought it was a fantasy, but what the light curtain said was basically true, maybe this kind of food really exists in the world. "

"Your Majesty will do your best to fight for it. "

The miraculous methods of the light curtain have been verified, and even if they want to refute it, they can't find any evidence.

Ying Zheng didn't say anything when he heard this.

I have long regarded this kind of food as the staple food of Daqin in my heart!

Han dynasty.

Liu Bang got up and paced in the main hall.

As the crops of popular science become more and more advanced, their role becomes more important for a country.

"Twenty times more than cereal..."

"Twenty times more. "

If the yield of sweet potatoes is only several times that of grains, he can still keep his composure.

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

He couldn't imagine.

If only the Han Dynasty could get this crop.

How many times can the population of a country increase!?

If he really got the sweet potato to the Han Dynasty, he might be able to become the Ming Jun in the mouth of future generations.

Xiao He stepped forward and said solemnly: "The minister will do his best to assist Your Majesty!"

Fan Xu laughed and roared: "Your Majesty, we will definitely do our best." "

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

......

Shu.

Liu Chan stared blankly at the light curtain.

Zhuge Liang didn't know when he pulled his sleeve, his eyes were full of longing for sweet potatoes.

'I know, don't worry, father. ’

Liu Chan knew it was time for him to make a move!

Just like the previous one, there is a rush to answer the question, and it is directly blindly selected.

If he is right, his father will definitely be impressed by himself.

Tang dynasty.

The eldest grandson Wuji, Fang Xuanling and others knelt on the ground and shouted:

"Your Majesty, this kind of divine food will definitely make Datang more prosperous!"

"At that time, I, Datang, don't need to use the means of harmony to compromise the grassland people!".

Cheng Yanjin clenched his fists excitedly.

If you can increase the grain output of the Tang Dynasty several times.

He will be able to lead more soldiers.

When the time comes, with heavy troops in hand, there is no need to worry about the steppe people coming!

There is no need to stabilize them with friendly means.

"Damn the prairie people, you Cheng Biting Grandpa Jin will lead hundreds of thousands of troops to your doorstep when the time comes, see how arrogant you are!"

Li Shimin's chest rose and fell violently.

For the prosperity of the Tang Dynasty, he paid too much and lost a lot.

Harmony is a scar in his heart.

A big country actually needs friendly means to protect the security of its frontiers.

When he married his daughter to the grassland, his own heart was not good.

..................................

Song dynasty.

Zhao Kuangyin was surprised.

"Sweet potato?".

"The yield per mu of this thing is so high!".

"I don't know if I have a fate......

He was reorganized by the light curtain several times, and his heart became Buddhist.

If you can get it, you will take it, and you will not be disappointed if you can't get it.

Keep a normal mind.

Otherwise, he was worried that he would be emotionally influenced by the light curtain all the time, and he would easily have a short life.

Ming dynasty.

Zhu Yuanzhang is completely crazy!

Looking at the light curtain, he shouted excitedly:

"We are ordinary people, so we like grain with high yields!"
