Datang: I was exposed by Princess Changle

"You can see enough!"

Li Lizhi looked at the eight of them with a half-smile.

The eyes of the eight of them immediately lit up when they heard this!

There is really a fetish with a yield of nine thousand catties per mu-sweet potatoes!

Lin Xuan, who was on the side, ordered lightly after hearing the words: "Yang Xun, open this land and have a look!"

Hearing Lin Xuan's order, Yang Xun nodded slightly, and quickly got off the ground.

He skillfully picked up the hoe and started digging in the ground.

After digging a few times, Yang Xun stopped.

This Yang Xun was originally a scholar. After his parents died, he rushed to Chang'an City to take the imperial examination.

In the Tang Dynasty, subjects were set up every year to obtain scholars.

But it is a pity that he loses his name every year, six times in a row.

His own family was not rich, and the money he brought with him before going to Chang'an was all his wealth.

Migui in Chang'an is not easy to live in!

He lived frugally for six years in Chang'an.

After failing for the sixth time, he finally ran out of money.

It's the end of the mountain!

The failure of the rankings for six consecutive years has dealt a heavy blow to his self-confidence and ambition.

Sun Shan lost his name again in the sixth year, which finally made him disheartened.

He returned to Lantian County in a daze.

It was Lin Xuan who took him in when he was the poorest and dying from starvation for three days and three nights.

For him, Lin Xuan is his reborn parents, his savior!

Because he has a strong interest in farming, he is now in charge of cultivating Lin Xuan's experimental field.

Yang Xun scraped away the soil and picked up the sweet potato with his hands.

I saw a huge purple-red fruit wrapped in soil appearing in everyone's eyes!

A group of eight people looked at the sweet potato in Yang Xun's hand with surprise.

"This...is a sweet potato? It's such a big one!"

The eyes of the sixth-class maid Le Guoer were full of curiosity, it was the first time she had seen such a strange thing!

"Is this food edible?"

"Of course it can be eaten, otherwise why grow it? And one tube is full!"

Yang Xun gave her a blank stare.

But that's not all.

While speaking, I saw Yang Xun pull up a cane in his hand, and a series of purple-red fruits appeared in front of everyone's eyes.

He pulled up the surrounding vines again, which were also a series of sweet potatoes!

The field is full of sweet potatoes!

Could it be that sweet potatoes are buried in every inch of the soil?

Yang Xun pulled up the vines one by one, and the strings of sweet potatoes kept flying in his hands.

A beautiful arc was drawn in the air.

This idea, under the gaze of everyone, has been confirmed step by step!

Chapter 097 It's too incredible!

Seeing this situation, a group of eight people opened their mouths wide, their faces full of shock!

There really is such a high-yielding thing!

Nine thousand catties of grain per mu!

It's unheard of, unheard of!

"Such a high yield of gods, one can eat enough, this... this can completely become the foundation of my new staple food in the Tang Dynasty!"

The imperial doctor Luo Wuwei grabbed a sweet potato, his eyes burst into strange brilliance!

At this moment, he was thinking, no matter what, he should report this matter to His Majesty as soon as possible!

It is best to deliver this sweet potato to His Majesty as soon as possible!

Your Majesty will be very excited!

"Mr. Lin, is this sweet potato easy to grow?" the imperial doctor Luo Wuwei asked excitedly, holding the sweet potato in his hand tightly.

"It's not difficult." Lin Xuan said lightly.

After Lin Xuan paused for a moment, he explained lightly: "Before planting sweet potatoes, you need to dig the ground first."

"Break the hard and large clods in the ground and loosen them."

"The planting can only be carried out after the ridges are dug and the planting trenches are dug."

"After you've grown the seedling, trim its roots a bit."

"Afterwards, the treated sweet potato seedlings are transplanted and planted in the planting trenches in the ground."

"Then pour water in the planting ditch hole, and then cover the root system at the bottom with soil."

"I usually water and loosen the soil, and when I have time, I can apply fertilizer and weeding."

"After fifteen days, it can be harvested when it is fully ripe."

Lin Xuan said lightly.
