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

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

Zhu Yuanzhang is like seeing the love food in his dreams.

Boy.

This sweet potato is long, one is bigger than his fist!

It's so appealing.

In comparison, wheat and rice are completely insufficient, and the yield per mu is painfully low.

"Father, this is exactly the food that Daming needs most at present. Zhu Biao was also excited.

The father and son reacted almost identically.

Queen Ma's face was full of surprise.

With such a high yield per mu, can it 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 in Fujian Province who had been doing business in Luzon for many years, and his son Chen Jinglun, saw that a root crop called "sweet potato" was planted locally, and the root was "as big as a fist, the skin color was vermilion, the heart was crisp and juicy, it was edible both raw and cooked, and the yield was high, and it was barren and barren." 】

[He thought that his hometown of Fujian had many mountains and few fields, barren land, and insufficient food, so Chen Zhenlong was determined to introduce sweet potatoes to China. 】

[In 1593, Luzon was under colonial rule, and sweet potatoes were regarded as a strange commodity and "forbidden to leave the country". 】

[After careful planning, Chen Zhenlong "took the potato vine and twisted it into the water rope", and smeared sludge on the surface of the rope, and in the early summer of 1593, he cleverly escaped the inspection of the colonizer checkpoint and "had to cross the sea". 】

[Sail for seven days and return to Xiamen, Fujian Province in the late fifth lunar month. 】

[Sweet potato comes from outside the territory, and Fujian people call it "sweet potato" because of it. 】

[Chen's introduction of sweet potatoes has been discussed in the Ming dynasty Xu Guangqi's "Complete Book of Agricultural Administration" and Tan Qian's "Jujube Forest Miscellaneous". 】

【......】

Smack!

Zhu Yuanzhang slapped his thigh violently!

He never imagined that sweet potatoes were in Luzon.

And that small country actually secretly hid such a good thing, deliberately not letting others find out.

"Okay, it's very good, this small country has been hiding from us for so long!".

Zhu Yuanzhang is not a good-tempered person.

He was almost angry.

The people of the Ming Dynasty were hungry, but Luzon put such good things and didn't offer them, and they secretly hid them.

Even Zhu Biao, who has always been known for his benevolence, looked angry at this time.

"How daring!".

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

Zhu Yuanzhang immediately ordered: "Where is Xu Da? Quickly send a holy decree to the lord of Luzon, obediently offer sweet potatoes, otherwise wait for the soldiers and horses to fight over." "

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

He was also so angry that his teeth were itching.

It depends on how the lord of Luzon chooses.

If he didn't know what to do, he wouldn't mind snatching it directly.

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

Qin Dynasty.

Ying Zheng has been blinded.

"America?".

"Luzon?".

"The widow has never heard of it at all. "

It's too painful to not get such good food.

Zhao Gao thought for a while and replied: "Your Majesty, this America is estimated to be far away from Great Qin, but this Luzon can be reached in seven days. "

Ying Zheng came to his senses.

That's right.

Luzon is certainly not far from Great Qin.

It's just that I don't know if there are sweet potatoes in its territory now, and if I can't find it, I can only look for America.

It seems that the plan to attack Baiyue in the south will be some time in advance.

Shu.

Zhuge Liang racked his brains and couldn't think of where Luzon was.

Otherwise, he would have to bring the sweet potatoes back to Shu with his life.

[The rush to answer the question starts!].

[May I ask what is the name of the first person in Huaxia to bring sweet potatoes back to China?].

[Option 1: Liu Huaqiang].

[Option 2: Bald head].

[Option 3: Chen Zhenlong].

[Option 4: Zhao Gao].

[Option 5: Cai Dakun].

Liu Chan's eyes lit up.

That's the opportunity he was waiting for.

didn't wait for Zhuge Liang to finish reading the content of the question.

Liu Chan got up and shouted, "Option two!".

[Answer incorrect!].

"Huh?".

Liu Chan's expression froze, and he didn't even dare to look at the location of his father.

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

Tang dynasty.

When Li Shimin was thinking about where America and Luzon were.

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

He glanced very cursoryly.

Almost instantly, I saw three words that were somewhat familiar, and I had seen them in popular science before.

There wasn't much hesitation.

He shouted directly, "Option three!".

[Correct!].

[Congratulations to Li Shimin of the Tang Dynasty for completing the rush and obtaining 10,000 catties of sweet potatoes. 】

Bang la blah.

A large pile of sweet potatoes bigger than a fist fell from the sky.

"Congratulations, Your Majesty!".

The minister of the DPRK and China knelt on the ground and shouted.

Li Shimin is still in a state of enlightenment.

He didn't even read the question, but he was familiar with option 3, so he chose it directly.

I didn't expect it to be a real success!

God bless the Tang Dynasty.

God bless the Tang Dynasty.

Li Shimin's heart is sweeter than eating dates.

Looking at a large number of sweet potatoes, he believes that in a few years, Datang will usher in an unprecedented prosperity!

Decades later.

The population of Datang has doubled.

At that time, there is no need to be afraid of the steppe people at all.

Even if you use human heads, you can pile them to death!

Ming dynasty.

Zhu Yuanzhang didn't even see what the title was.

was answered by Li Shimin!

He suspected Li Shimin of cheating!

Or simply as good luck as it exploded.

Otherwise, how could it be so fast?

Didn't get sweet potatoes.

Let him pour all his anger on Luzon.

"I'm so angry, write another letter to the lord of Luzon, and ask them to hand over another 100,000 taels of silver!"

"Yes!".
