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

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

Zhu Yuanzhang seemed to have seen the love food in his dream.

Good guy.

These potatoes are bigger than his fist! They are so cute.

In comparison, wheat and rice are not impressive at all, and the yield per mu is so low. Heartache

"Father! This is the food that Ming Dynasty needs most at present."Zhu Biao was equally excited.

The reactions of the father and son were almost the same.

Queen Ma's face was full of surprise.

Can such a high yield per mu of food really be grown from the ground?

【Popular science continues!】

【Sweet potatoes are native to South America】

【It is generally believed that sweet potatoes were introduced to China during the Ming Dynasty】

【During the Ming Dynasty, Chen Zhenlong, a native of Changle, Fujian Province, and his son Chen Jinglun, who had been doing business in Luzon for many years, saw a root crop called"sweet potato" growing there. It is edible when cooked, has high yield, and can be widely planted and resistant to barrenness."】

【He thought of his hometown in Fujian, which has many mountains and few fields, poor land and insufficient food, so Chen Zhenlong decided to introduce sweet potatoes to China.】

【In 1593, Luzon was under colonial rule, and sweet potatoes were regarded as a rare commodity and were"not allowed to leave the country.""】

【After careful planning, Chen Zhenlong"took potato vines and twisted them into the water-drawing rope" and smeared mud on the rope. In the early summer of 1593, he cleverly avoided the inspection of the colonial checkpoint and"began to cross the sea.""】

【After seven days of sailing, we returned to Xiamen, Fujian Province in late May of the lunar calendar】

【Because sweet potato comes from outside the region, people in Fujian call it"sweet potato"."】

【Chen's introduction of sweet potatoes was discussed in Ming Dynasty's Xu Guangqi's"Agricultural Policy Complete Book" and Tan Qian's"Zao Lin Zazu".】

【......】

Snapped!

Zhu Yuanzhang slapped his thigh so hard!

He never imagined that sweet potatoes were in Luzon.

And that small country actually secretly hid such a good thing, deliberately preventing others from discovering it.

"Okay, great, this small country has kept it secret from us for so long!"

Zhu Yuanzhang is not a good-tempered person.

He was about to explode with anger.

The people of the Ming Dynasty were starved of food, but Lu Song just ignored such good things and refused to offer them as offerings, and even hid them secretly.

Even the people who have always been known for their kindness Zhu Biao also looked angry at this time.

"How brave!"

"It's just a small country, how dare it do this.

Zhu Yuanzhang immediately ordered:"Where is Xu Da?" Send an imperial edict to the Lord of Luzon as soon as possible and offer the sweet potatoes obediently, or else wait for the soldiers and horses to attack him."

Xu Da, who had been waiting for a long time, immediately followed the order.

He was also very angry.

It depends on how the king of Luzon chooses.

If he doesn't know what to do, I don't mind grabbing it directly.........................

Qin Dynasty.

Ying Zheng is already confused

"America?"

"Luzon?"

"I have never heard of where it is."

It is too painful to not get such good food.

Zhao Gao thought for a while and replied:"Your Majesty, America is probably far away from Daqin, but Luzon can be reached in seven days across the sea."

Ying Zheng calmed down.

That's right.

Luzon is definitely not far from Daqin.

But I don't know if there are sweet potatoes in its territory now. If you can't find it, you can only look for America.

It seems that the plan to attack Baiyue southward, We need to advance some time.

The Kingdom of Shu.

Zhuge Liang racked his brains and couldn't figure out where Luzon is.

Otherwise, he would have risked his life to bring the sweet potatoes back to the Kingdom of Shu.

【The Q&A session begins!】

【What was the name of the first person in China who brought sweet potatoes back to China?】

【Option 1: Liu Huaqiang】

【Option 2: Bald and strong】

【Option three: Chen Zhenlong】

【Option 4: Zhao Gao】

【Option 5: Cai Dakun]

Liu Chan’s eyes lit up.

This was the opportunity he was waiting for.

Zhuge Liang didn't wait until he finished reading the question.

Liu Chan stood up and shouted:"Option 2!"

【wrong answer!】

"ah?"

Liu Chan's expression froze and he didn't even dare to look at where his father-in-law was.............................

Tang Dynasty.

Li Shimin was thinking about where America and Luzon were.

A pop-up window suddenly popped up in the light screen.

He gave it a very cursory glance.

Almost instantly I saw three familiar words that I had seen in popular science before.

There wasn't much hesitation.

He shouted directly:"Option three!"

【correct answer!】

【Congratulations to Li Shimin of the Tang Dynasty for completing the answer and winning 10,000 kilograms of sweet potatoes. 】

Crash.

A bunch of sweet potatoes bigger than your fist fell from the sky

"Congratulations to Your Majesty!"

The ministers knelt down and shouted.

Li Shimin was still in a state of enlightenment.

He didn't even read the question. He just saw that option three was very familiar, so he chose it instantly.

Unexpectedly, it really succeeded!

God bless the Tang Dynasty.

God bless the Tang Dynasty..Li

Shimin's heart was sweeter than eating candied dates.

Looking at a lot of sweet potatoes, he believed that in a few years, Datang would usher in an unprecedented prosperous age!

In a few decades, the population of Datang would have doubled several times.

By then, it would be completely Don't be afraid of the grassland people.

You can kill them even with heads!

In the Ming Dynasty,

Zhu Yuanzhang didn't even see clearly what the question was. He was answered by Li Shimin!

He suspected that Li Shimin was cheating!

Or he was just lucky enough to explode.

Otherwise, how could he act like this? Quickly?

Didn’t get the sweet potato.

Let him take all his anger out on Luzon.

"We are so angry that we write another letter to the leader of Luzon and ask them to hand over another hundred thousand taels of silver!"

"yes!"....................................

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

【Fifth place: sweet potato, science popularization completed】

【After 3 minutes, the fourth place of popular science begins: corn! 】
