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

All the emperors didn't expect that the light curtain would actually play this hand.

At the time when popular science was the most complicated and boring knowledge, a rush to answer suddenly appeared.

Qin Dynasty.

Ying Zheng just closed his eyes.

A pop-up window pops up on the light curtain.

Li Si's eyes widened, and he shouted excitedly: "I'll answer for Your Majesty, it's option four!".

[Hint, can only be answered by the emperor of each dynasty in person, to be valid.] 】

[Hint!].

[The emperor has completed the answer!].

Li Si was suddenly lost his temper.

It's not that his answer is invalid, it's that someone answers faster than him!

Which dynasty is the emperor?

Ying Zheng saw the content on the light curtain, and the corners of his mouth twitched slightly.

He only took less than two breaths to relax, and the reward was gone from !! of him

......

Han dynasty.

"The fourth!".

"Option four!".

"Your Majesty, get up quickly and answer the question!".

The civil servants are gossiping and eager to open one more mouth.

It's the same in the court as in the vegetable market.

Liu Bang, who had just closed his eyes and rested, was woken up, and he said angrily: "Silence!".

Only then did the civil servant quiet down.

Liu Bang glanced at the audience and soon noticed that something was wrong.

The eyes of the crowd were regretful, as if they had just missed a great good deed.

Fan Hao turned his head and complained with a stomach full of resentment: "Your Majesty, you slept well this time, and the reward was given away." "

Liu Bang: "..."

He looked up at the blindfold.

The bowels of regret are blue.

.........

Shu.

"It's a good soup, I've warmed up a lot after drinking it. "

Liu Chan drank the ginseng soup with a beautiful expression, but he didn't notice that Zhuge Liang's face was terrifyingly dark.

"Father, it's all to blame!".

He reacted instantly.

I feel a little cold when I sit outside when I am young and strong.

Xiang's father is already old, and his health is far inferior to that of young people.

He only cared about drinking ginseng soup for himself, and didn't prepare a bowl for his father.

Liu Chan felt guilty on his face, and instructed the servant standing on the side: "Come and give a bowl of ginseng soup to my father." "

Zhuge Liang couldn't keep his composure, pointed to the sky with a fan, gritted his teeth, and said: "Your Majesty! "

Liu Chan was furious when he saw Zhuge Liang.

Hurriedly shrunk his neck and said aggrievedly: "Yes, father, I just look up." "

Then, he was stunned.

also understood the reason why Zhuge Liang was so angry.

...........

Tang dynasty.

The eldest grandson Wuji thought quickly in his head.

Soon, in reminding Li Shimin and answering the light curtain directly, he chose the latter.

"Option four!".

"It's option four!".

[Hint, only the emperors of each dynasty answer is valid.] 】

[Hint!].

[The emperor has completed the answer. 】

The voice of the eldest grandson Wuji attracted Li Shimin's attention.

Li Shimin first saw the stunned expression of the eldest grandson Wuji, and then followed his gaze to the light curtain.

"Only my answer works?".

No wonder Fang Cai shouted loudly, but there was no response. "

He sighed helplessly: "It's all to blame." "

At the same time, he guessed in his heart, who was the one who succeeded in answering?

And what rewards can you get?

........

Song dynasty.

Zhao Kuangyin inexplicably missed the rush to answer the link.

When he reacted and looked up at the sky, the rewards for answering were in the hands of others.

Zhao Kuangyin: "......

".

This thing has nothing to do with me.

That's it.

Ming dynasty.

Zhu Yuanzhang stared at the light curtain almost the whole time, unable to take his eyes off it.

He really wanted to know why sugar cane could grow so stout.

[Rush to answer the question!].

[What kind of sugar can be extracted from sugarcane?].

[Option 1: Glucose.] 】

[Option 2: Maltose.] 】

[Option 3: Fructose.] 】

[Option 4: Sucrose.] 】

[Option 5: Lactose.] 】

"Uh-huh!?

".

Zhu Yuanzhang's expression stiffened slightly.

It was almost instantaneous.

I let the reward slip away last time, and I can't let it go this time!

His eyes quickly swept over the answer, and then he fixed his gaze on the fourth.

In the Ming Dynasty, it was called sugar.

However, since it is sugar cane, the extracted sugar is of course called sucrose.

He had also seen it in the popular science of the light curtain before.

"The fourth!".

[Successful answer!].

[Congratulations to Zhu Yuanzhang of the Ming Dynasty for completing the answer. 】

[Reward: 5,000 kilograms of sugarcane seedlings of Guitang No. 42, and obtain the "Yellow Mud Water Sugar Method".] 】

[Tips: Guitang No. 42 has an average yield of 7 tons per mu and an average sugar content of 15.3%. 】

[Yellow mud water drenching sugar method: first appeared in the middle of the Ming Dynasty, in ancient times is an efficient process for making white sugar, the specific steps are ......].

The next second.

A large number of sugarcane seedlings appeared out of thin air, and there was a process flow chart that recorded the "yellow mud water drenching sugar method".

Zhu Yuanzhang had an ecstatic expression on his face.

Ming Dynasty one stone 50 kilograms.

The yield of 8 tons per mu is 160 stone !! per mu

Completely crush other crops!

And Guitang No. 42 sugarcane also has an amazingly high sugar content.

Coupled with the rewarding process of refining white sugar, Daming can even rely on white sugar to feed the people!

Zhu Yuanzhang even fantasized.

When a famine occurred in a place, he didn't even need to allocate silver, and directly sent dozens of truckloads of white sugar for disaster relief.

It is also very convenient to eat, and it is no problem to eat it directly or soak it in water.

More importantly, as long as the white sugar is not damp, the shelf life is far beyond that of ordinary grains.

Even in modern times, it is a strategic-level material.

"Congratulations to Your Majesty, congratulations to Your Majesty! With this crop, it has been vigorously popularized in the Jiangnan region, and I will be able to recover in just a few years!"

Li Shanchang smiled and congratulated loudly.

The stronger the Ming Dynasty, the more benefits he would naturally get from it.

"Congratulations to my father!" Zhu Biao also congratulated.

He has a more long-term vision.

After the Ming Dynasty recovered, it could also monopolize this method of sugar production, and merchants had to pay money if they wanted to use it.

In this way, the treasury of the Ming Dynasty was enriched.

Queen Ma swept away the gloom on her face before, "Chongba, this time I took two good things." "
