Datang: My identity as prince was exposed by Li Er

Hou Ji got on the ship.

Along the way, he wrapped himself up so that no one could recognize him.

By being sent back to Datang this time, he was taking a huge risk in case he was recognized by Hou Junji or anyone in the Hou family.

Hou Ji's life was in danger.

But he is not afraid.

His life was given to him by Princess Li Qing of Goryeo, and he repaid the favor

……

Tai Chi Palace.

Honglu Temple.

The envoys of Goryeo, Baekje, and Silla all begged Fang Yiai to take them to see Li Shimin.

Fang Yiai naturally refused.

He knew why the envoys from the three countries came this time.

My father, Fang Xuanling, told me that no matter what, the envoys from the Three Kingdoms must be stopped.

It is impossible for Datang to rescue any country in the Three Kingdoms, so out of sight is out of mind

……

It’s worth it.

Fang Yiai asked Du He to go to the outskirts of Wannian City with him.

Ever since I heard Li Yi say that these sweet potatoes can save tens of millions of lives.

The two of them became excited.

When they saw Cheng Chumo's glory some time ago, the two of them were already envious of him. They swore that they would also do something glorious so that they could gain respect for their father.

"Brother Du, so early?"

"Brother Fang, are you placing your orders so early?"

The two brothers met each other and exchanged greetings.

Fang Yiai sighed and said:"Hey, the envoys of the Three Kingdoms are asking Datang to rescue them. There is only so much food, and no one can save them. No, those people are pestering me. , I was bored to death, so I came here after checking the value. Du

He looked at Fang Yiai sympathetically, then thought of something and said,"You said there are not enough grains and potatoes in Taicang Liang now, but if the sweet potatoes mature, wouldn't we be able to rescue them?""

Looking at these thousands of acres of sweet potatoes, Fang Yiai also fell into deep thought.

"Just a few thousand acres of sweet potatoes can't do much.

Du He nodded:"Yes.""

"No matter, let's go see how the sweet potatoes turned out."

While talking, the two of them came to the field.

They have been taking care of the sweet potatoes for a long time these days.

They are even familiar with the growing habits of sweet potatoes, how to water them, how to cook them, etc.

Here, they see a large field of sweet potatoes. The leaves are densely packed, covering thousands of acres of land

"The teacher said that sweet potatoes, like potatoes, grow in the soil." Du He said

"Well, it looks like it’s almost done. Why don’t we dig it in and give it a try?"

While talking, the two of them didn't mind being dirty. They squatted down and dug out the mud with both hands. Not long after, a huge dark red fruit emerged from the mud.

The first sweet potato finally showed its head. It was huge because it was roughly as thick as an ordinary child's forearm.

Naturally, it could not be compared with the giant and thick sweet potatoes of later generations. The two continued to dig up the soil gradually, and the long strips of sweet potatoes like lotus roots were completely exposed. In front of them.

Huh...

Fang Yiai and Du He were stunned, and kept their eyes wide open.

In fact, it was not that they had not done anything before. It was just that at that time, most of the sweet potatoes had not yet formed, and they were just digging them open to observe their habits.

This It's... so big!

Keep digging...

Under this vine, connected to this sweet potato, another sweet potato shows its rudimentary shape.

This sweet potato... looks more like a potato. If you compare it For humans, then it is probably more like Teacher Pan among humans than the first long-shaped sweet potato.

Li Yi comforted himself that Teacher Pan is not bad, after all, concentration is the essence.

When the second one is completely exposed and unearthed, there will be......

A seedling is a large bunch. Although it is not as good as grapes and can produce dozens of fruits, this seedling actually produced five sweet potatoes. Some were large, some were small, and one was even Smaller than an egg, this child... well, it's obviously hopeless.

But the big one is as thick as a lotus root, more than an inch long.

The two looked at each other, and they both found that their eyes were as big as eggs!

"Brother Fang, how heavy do you think this is?"

"Three kilograms...well, five kilograms are all there!"

After saying this, the two of them fell silent to each other, and then both of them trembled a little.

"Walk! Go tell your mentor!"Du He stood up suddenly. After squatting for a long time, his vision went dark, and he almost sat down again.

Fang Yiai quickly helped Du He, and the two of them went to Xiuwenfang tremblingly.

"Teacher, teacher!"

From a distance, I heard the voices of Fang Yiai and Du He, with a hint of trembling in their voices.

Shangguan Yi greeted the two junior brothers curiously and said,"What's the matter?"

"The knots are over, the sweet potatoes are ripe, it’s so spectacular!

Shangguan Yi asked curiously:"What is spectacular?""

"Do you believe that the yield per mu is fifty shi?"

"Don't make trouble!"Shangguanyi thought these two guys were joking.

Even for potatoes, a magical creature, the yield per mu is only twenty or thirty kilograms.

Are these sweet potatoes even more powerful than potatoes?

"real!"

Du He couldn't help but gasp.

Shangguan Yi didn't dare to delay:"I'm going to find my mentor."

Not long after, Li Yi walked out with his hands behind his back.

He said calmly:"The yield per mu is fifty dan, is it so little?"

Young Master?

" Du He and Fang Yiai had black lines on their faces.

How many people must have been slapped in the face by this!

While they were talking, a group of people came to the outskirts of Wannian City.

Tenant farmer Wang Zhuang and the others also came over.

"Master, just wait, I'll show you!"

Du He was barefoot, and Fang Yiai followed closely behind.

The two couldn't help but began to pull the fields.

"have a look!"

"You all take a look!"

After the sweet potatoes came out,

Wang Zhuang and other tenant farmers were dumbfounded and couldn't help but gasped:"Oh my god!

Wang Zhuang quickly weighed it with his hands,"No!" Give me the scale!"

Someone handed over a weight.

"More than five pounds!"

"Do the math, do the math, how many kilograms can be produced per acre!"

"One five makes five, two five makes ten……"

Everyone did not dare to neglect, they all started counting with their fingers.

But at this time, someone took off the backpack from his back and said excitedly:"I have an abacus, I have an abacus." He took out the abacus from the backpack and crackled for a while.

For a long time, Li Yi became impatient:"Have you figured it out?"

"……"

What I got was silence...

Nima!

What a bunch of rubbish!

After a long time, someone finally calculated it,"The yield per mu... Oh my God, fifty dan, no, fifty-five dan!"

All of a sudden.

Shangguan Yi's eyes widened.

At first he thought Du He and Fang Yiai were joking.

But now, the real results are before them, and they have to believe it!

Shangguan Yi murmured:"The Tang Dynasty continued the Sui system, and among the measurement units of the Sui people, one stone was one hundred and twenty kilograms.

Fifty-five stones...

Damn it! Five or six thousand kilograms... this……"

Shangguan Yi's mind was already buzzing.

It’s not a big problem to save people or a country!

Damn it!

This sweet potato is simply much sharper than potatoes! _Feilu reminds you: three things about reading - collection,
