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

Han dynasty.

Liu Bang couldn't help but be crazy when he watched the video.

I think that when he was in Pei County, although he lived better than ordinary people, he could wear sackcloth.

It's really uncomfortable to wear.

Many ministers in the audience felt more deeply.

Before accompanying Liu Bang to rebel, most of them were ordinary people, and the clothes they wore were really tattered, and they were patched up.

The elder brother in the family wears it, and the younger brother wears it.

The key is not to keep warm, and the air leaks when it comes to the hole in winter.

Now that I'm living a good life, I've thrown away all my previous clothes.

Thinking that more ordinary people still wear such clothes, many ministers can only sigh that the common people are miserable no matter what dynasty.

Shu.

Zhuge Liang teary-eyed and gently wiped the corners of his eyes.

Before meeting Liu Bei, he personally farmed in the fields.

He knows best how hard ordinary peasants live.

I had to get up early in the morning to work in the fields, and I could only eat two meals a day, so I couldn't eat enough and couldn't dress warmly.

A gust of wind blew.

Zhuge Liang shuddered.

Winter is coming.

The people of Shu are going to suffer again.

Liu Chanzui was born with a golden key, and he didn't really understand what it felt like to wear Mai on his body.

But he knew that as an emperor, he had to do something for the people.

Tang dynasty.

Li Shimin looked at the light curtain video, the cotton that grew very well, and said enviously:

"Why isn't my Datang's cotton so good?".

In the Tang Dynasty, cotton was available, but it was mostly planted in the border areas.

Almost all of the interior is grown with food.

It's not that I don't want to grow cotton inland.

Because grain production is very low, cotton cultivation in the interior will lead to even more insufficient food.

And cotton cultivation is the most cost-effective in the frontier.

The steppe people like to grab grain, so they will plant cotton in the frontier.

Due to the fact that the handicraft industry of the steppe people is extremely underdeveloped.

Even if they grabbed a lot of cotton, they couldn't make it into clothes and quilts.

In the end, it was necessary to sell the snatched cotton to the Tang Dynasty at a low price.

Li Shimin sighed: "When the territory of Datang is full of cotton, my Datang can be regarded as a real prosperous era." "

Song dynasty.

Zhao Kuangyin frowned and pondered.

"At the end of the Song Dynasty and the beginning of the Yuan Dynasty, cotton was planted in the ...... mainland".

Suddenly, his gaze froze.

"The Yuan Dynasty was the regime established by the steppe people, and my Great Song Dynasty finally died in the hands of the steppe people?"

The sixteen states of Yanyun have not yet been recovered.

This has always been his heart disease.

Now he actually told him that the Song Dynasty died at the hands of the steppe people.

Since I already know where the future will go.

He can't afford to repeat the mistakes of the past.

Taking advantage of the current time to strengthen military training and consolidate military strength, there is still a chance to change the outcome of the Song Dynasty.

Day.

Zhao Kuangyin ordered to expand the army!

Recapture the Sixteen Prefectures of Yanyun within three years!

Ming dynasty.

The corners of Zhu Yuanzhang's eyes were moist.

As the most legendary emperor, his life was also extremely miserable.

When I was a child, my family starved to death.

As for whether he can wear warmth, it is not within his consideration.

"Sister, we must let the people of Daming be fed and clothed, and we can't let them see their families die in front of them like we did when we were children. "

Zhu Yuanzhang looked at Queen Ma and said his promise.

"Juhachi, I believe you. Queen Ma replied affectionately.

The two have been together for many years.

Needless to say, you can understand the other person's thoughts.

Zhu Biao's eyes were slightly red, "Father, son, and son also swear that they will make the people of Daming the happiest people in the world." "

"Okay, Biao'er, we also believe you, and it will definitely be the appearance of Mingjun in the future. "

The three of them hugged each other tightly.

Zhu Di: "......".

Co-authoring me is redundant.

He also has the ambition to soar to the sky, but Zhu Biao, Zhu Yuanzhang's "biological" son, stood in front of him.

At most, he can only be a vassal king who goes into battle to kill the enemy.

Qing Dynasty.

Kangxi looked at the video playing in the light curtain, and only felt a burst of novelty.

If only the light curtain had been playing interesting videos.

He can tolerate it.

He stared carefully at the light curtain, ready for the rest of the answer.

[Rush to answer the question!].

[When is the flowering period of cotton?].

[Option 1: June ~ October].

[Option 2: August ~ December].

[Option 3: January ~ June].

[Option 4: March ~ August].

"Choose ......" Kangxi was overjoyed in his heart, and he wanted to come whatever he wanted.

[End of rush answer.] 】

[Congratulations to the three of them for completing the answer at the same time, with a difference of less than 0.2 seconds.] 】

[Congratulations to Yingzheng of the Qin Dynasty, Liu Bang of the Han Dynasty, and Liu Chan of the Shu Kingdom for their success!].

[The three of them respectively obtained: 500,000 catties of cotton. 】

[Cotton planting method: open, is preparing popular science. 】

[For the manufacturing process of cotton-related products, please refer to the "Credit Mall" for details. 】

？？？

Kangxi's mouth opened halfway and was stuck.

He's clearly already answered!

Why doesn't it have its own name on it?

Could it be that this damn light curtain was really aimed at him!?

The surrounding ministers didn't dare to say anything when they saw this situation, and lowered their heads silently.

There was silence for a while.

Kangxi roared angrily: "The cannon I want hasn't been built yet?"

"The Emperor... Back to the emperor, the cannon is still making ......" the eunuch replied tremblingly.

"I don't care, get it out as soon as possible, or I'll cut down all those craftsmen!"

Kangxi was already furious.

All he wanted to do now was to knock down the light curtain in the air.

This thing not only bewitched the people of the Qing Dynasty and added trouble to him, but also deliberately targeted him and did not reward himself.

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

It's the opposite.

The people of the Qin Dynasty, the Han Dynasty, and the Shu Kingdom were crazy.

I actually got so much cotton at one time.

As long as those in power are not stupid.

In a few years, cotton will definitely be able to be planted on a large scale in the country.

They also had the opportunity to wear warmer and more comfortable clothes than sackcloth and low-quality hides.
