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

Han Dynasty.

Liu Bang couldn't help but be fascinated watching the video.

I remember that when he was in Pei County, although he lived better than ordinary people, he still wore linen clothes.

That thing is really uncomfortable to wear.

Many ministers in the audience were deeply moved.

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

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

The key is not to keep warm. In winter, air will leak from the holes.

Now that I am living a good life, I have thrown away all my previous clothes.

Thinking that more ordinary people still wear such clothes, many ministers can only lament that the ordinary people have a hard life no matter what dynasty they are.

Shu Kingdom.

Zhuge Liang's eyes were filled with tears and he wiped the corners of his eyes gently.

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

He knows best how miserable ordinary farmers live.

I have to get up early in the morning to work in the fields. I can only eat two meals a day, and I don't have enough to eat or keep warm.

A gust of wind blew.

Zhuge Liang shuddered.

Winter is coming.

The people of Shu will suffer again.

Liu Chan was born with a golden key in his mouth, so he didn't really understand what Mai felt like when wearing it.

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

Tang Dynasty.

Li Shimin looked at the cotton that was growing extremely well in the light screen video and said with envy:

"Why is my Datang cotton not so good?"

There was cotton in the Tang Dynasty, but it was mostly planted in border areas. Almost all food was grown in the inland.

It's not that they didn't want to grow cotton in the inland.

Because the grain yield is very low, growing cotton in the inland will lead to even less food.

And Cotton cultivation is most cost-effective in the border areas.

Prairie people like to grab food, so they should increase their cotton production in the border areas.

Since the grassland people's handicraft industry is extremely underdeveloped, even if they grab a lot of cotton, they will not be able to make clothes and quilts.

In the end, they will have to He sold the cotton he grabbed to the Tang Dynasty at a low price.

Li Shimin sighed:"When the territory of the Tang Dynasty is full of cotton, the Tang Dynasty will be truly prosperous."

Song Dynasty.

Zhao Kuangyin frowned and thought

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

Suddenly, his eyes narrowed

"Yuan Dynasty? At first glance, it sounds like a political power established by the grassland people. Will the Song Dynasty eventually fall into the hands of the grassland people?"

The Sixteenth Prefecture of Yanyun has not yet been recovered.

This has always been his heartache.

Now he is actually told that the Song Dynasty fell at the hands of the grassland people.

Since he knew the future direction, he cannot repeat the same mistakes.

Take advantage of now to strengthen military training, consolidate military strength, and return There was a chance to change the outcome of the Song Dynasty.

On that day,

Zhao Kuangyin ordered to expand the army!

Recapture the sixteen states of Yanyun within three years!

The Ming Dynasty.

Zhu Yuanzhang's eyes were wet.

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

His whole family starved to death when he was a child.

As for whether he could Dressing warmly is not a consideration for him

"Sister, we must ensure that the people of Ming Dynasty are fed and clothed, and we cannot let them see their family members die before their eyes like we did when we were children."

Zhu Yuanzhang looked at Queen Ma and said his promise

"Chongba, I believe you."Empress Ma responded affectionately.

The two have known each other for many years.

You don't need to say much to understand each other's thoughts.

Zhu Biao's eyes were slightly red,"Father, I also swear that the people of Ming Dynasty will become the happiest people in the world."

"Okay, Biao'er, we also believe in you, you will definitely be a wise king in the future."

The three of them hugged each other tightly.

Zhu Di:"......"

Co-authoring me is redundant.

He also had ambitions to reach the sky, but Zhu Biao, Zhu Yuanzhang's"biological" son, stood in his way.

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

Qing Dynasty.

Kangxi looked at the video played on the light screen and felt a sense of novelty.

If only the light screen kept playing interesting videos.

He can tolerate it.

He stared at the light screen carefully, preparing for the next Q&A session.

【Q&A session!】

【In what month does cotton bloom?】

【Option 1: June to October】

【Option 2: August to December】

【Option three: January to June】

【Option 4: March to August】

"select......"Kangxi was overjoyed, and whatever he thought of came to him.

【End of Q&A】

【Congratulations to the three people who completed the answer at the same time, with a difference of less than 0.2 seconds.】

【Congratulations to Ying Zheng of the Qin Dynasty, Liu Bang of the Han Dynasty, and Liu Chan of the Shu Kingdom for successfully answering!】

【The three of them received: 500,000 kilograms of cotton.】

【How to grow cotton: open to the public, science popularization is being prepared】

【For the manufacturing process of cotton-related products, please see the"Credits Mall""】

? ? ?

Kangxi opened his mouth halfway and got stuck.

He has clearly already answered!

Why is there no own name on it?

Could it be that this damn light curtain is really targeting him!! ?

The surrounding ministers did not 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?"

"emperor...Back to the emperor, cannons are still being made......"The eunuch shook his head and replied

"I don't care, get it out as soon as possible, otherwise I will kill all those craftsmen!"

Kangxi was already furious.

All he wanted now was to blow down the light curtain in the sky.

This thing not only confused the people of the Qing Dynasty and caused him more trouble, but also deliberately targeted him and refused to reward himself...................................................... to the opposite.

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

I actually got so much cotton at once.

As long as those in power are not stupid.

In a few years, cotton will surely be grown on a large scale in China.

They also had the opportunity to wear clothes that were warmer and more comfortable than linen and inferior animal skins.
