Belch.

Ye Xuanfeng was choked all of a sudden.

He wanted to hint that Ye Ling'er had missed Fang Jue, but Fang Jue deliberately talked about King Qin.

This made the old man even more depressed.

Whether it was Fang Jue or King Qin, Ye Ling'er originally had a chance, which could be described as an opportunity to soar into the sky.

However, it was all completely destroyed by her own sassy operation.

"I heard that Miss Ling'er has not been in a good mood recently, and she has dropped a lot of things at home...... After all, the Ye family is deeply favored by the emperor, you have to be careful, don't let her break the things given by the emperor......"

Fang Jue was a little gloating, and he didn't even hide it.

Ye Xuanfeng was a little stunned, he didn't expect the world's geniuses to be so stingy.

Such a talent should be more generous, and he won't be so cautious when he suffers a loss, right?

The pattern is a bit low.

"Sir, rest assured, according to the system, Ling'er can't use the things given by the emperor." Ye Xuanfeng said casually.

The Ye family still cares about this kind of regulation and will not give people a handle.

Fang Jue nodded, he planned to anger Ye Xuanfeng again.

This old man does not have a cardiovascular and cerebrovascular emergency, which can be stimulated.

"Your Majesty came that day and saw sweet potatoes and cassava, and I had something to show him, but His Majesty was too shocked at that time...... I was afraid of frightening him, so I didn't dare to say anything more. ”

Fang Jue looked at Ye Xuanfeng: "The old man came today, it's also time, that thing is just ready to be harvested, let's dig one up and taste it, right?" ”

"Dig what?" Ye Xuanfeng didn't feel good.

But listening to Fang Jue's meaning, it seems that there is still more productive food?

Dianichi handed over a hoe.

Ye Xuanfeng took it, followed Fang Jue, and went to the core of Fangjiazhuang.

He saw a piece of land, at least three acres or more, all planted with something, the color was not visible in the moonlight, but it was estimated to be green.

"There's nothing here?" Ye Xuanfeng said.

"Underground."

Fang Jue walked over and dug a hoe under a nest of rattans, bringing up a piece of dirt.

A few more hoes went down, and several huge fruits were dug out of the ground.

"Bigger than that sweet potato!" Ye Xuanfeng was shocked, the yield of this thing is only higher.

Fang Jue said: "This thing is called cold potato, the skin is thin and easy to peel, and it is juicy and sweet...... Whether it's a vegetable or a fruit, or as a staple food, it's fine. ”

Cold potatoes are generally not used as a staple food.

But there was once a famine, which was barely survived by cold potatoes, so it can also be said that it is a staple food.

Fang Jue peeled off a small one and handed it to the old man:

"Taste?"

The old man was not polite, took the cold potato and took a bite, and then his eyes lit up:

"It's delicious!"

This thing can be eaten raw or even cooked, which ...... In these special times, this is better than all the staples now!

Ye Xuanfeng instantly tasted this information: "If it is used as military food...... It can be used without fire for a short period of time, which is convenient for surprise attacks! ”

Fang Jue nodded, as long as the cold potatoes are dug out with soil, they can be stored for a long time without washing or hurting the skin.

"Lao Guogong is worthy of being a military person, this thing can indeed be used in this way, but it will lose moisture and umami if left for a long time."

As a food, cold potatoes have an undeniable disadvantage, that is, the storage time is not as good as other staple foods.

But if you cook it, its shelf life is too long.

"Sweet and refreshing, big and full, it looks like the yield should be higher than sweet potato cassava?"

Ye Xuanfeng looked at Fang Jue: "Sir, is the yield of this cold potato a secret?" ”

Fang Jue nodded: "Count, but it's okay to tell the old man, you have dedicated your life to the country, and you won't leak secrets." ”

"That's nature." Ye Xuanfeng was eager to know, and did not hesitate to use his reputation as a guarantee.

Fang Jue smiled and stretched out a finger.

"Only a thousand pounds?" Ye Xuanfeng was a little disappointed.

Fang Jue shook his head: "It's 10,000 catties...... Above. ”

The yield of cold potatoes is so terrifying!

Fang Jue also said that he was conservative, and if he really calculated it, even under the current conditions, the yield per mu could reach more than 12,000 catties.

Of course, it has to be planted according to Fang Jue's method, and the old method of slash-and-burn cultivation has to be improved.

"One, 10,000 catties ......"

Ye Xuanfeng held the cold potato stalk in his hand, and couldn't help but marvel and even tremble.

A grain with a yield of 10,000 catties per mu and can even be used as a staple food...... There is no need to say much about what this means.

"Paddy...... The average yield per mu settled by the household department this year has only ...... Four hundred and seventy pounds ......"

It's been a good year!

More than twenty times the difference!

Even if the nutrition of cold potatoes is worse than that of rice, it is not ten or eight times worse.

Ye Xuanfeng's simple old peasant thought told him that the Great Xia Kingdom had picked up a treasure!

"Sir is so calm, he really has a lofty vision." Ye Xuanfeng smiled bitterly, he saw Fang Jue's eyes looking at him, as if he was looking at a bun.

He was not angry, but felt that he should repair his relationship with Fang Jue.

……

Ye Guogong left, took the cold potatoes that Fang Jue gave him, and left first.

On the morning of the second day, Ye Guogong recovered from his illness for a long time and went to court for the first time.

After the dispersal of the dynasty, the old prince asked to see the emperor and went to the imperial study...... With cold potatoes.

In the imperial study, there was a lot of noise soon.

"What!?"

"10,000 catties per mu!?"

"Old man, I'm afraid you're not dizzy, how can you ......" Xiao Pingsi felt that this old man was not sick and not well.

10,000 catties, even Mr. Fang didn't dare to blow it like this!

Ye Xuanfeng said: "Last night, the minister went to Fangjiazhuang, Mr. Fang invited the minister to eat cold potatoes, and told the minister that the yield of this thing was ......."

"That'...... I also went that day, why didn't he say it!? ”

"Mr. Fang said that His Majesty's heart was surging that day, and he was afraid of scaring His Majesty."

"This ......"

……

Fangjiazhuang.

Classroom.

King Qin came early, and after he dispersed, he didn't even care about the errand arranged by His Majesty, so he hurried to class.

He couldn't wait to know the follow-up lessons, looking forward to how many mysteries there were in this world.

However, when the teacher came, he found out that he did not bring a globe.

The textbook is not yesterday's.

"Teacher, don't talk about geography today?"

"Well, I'll teach you math today."

Fang Jue handed the textbook to King Qin.

King Qin: "Sir, mathematics is mathematics?" ”

"Pretty much."

"Then I've also studied, sir, let's talk about geography......"

Fang Jue glanced at him playfully: "Your Highness are you sure you have learned?" ”

"Teacher, it's not a disciple who is entrusted to the university, my math grades from childhood to adulthood are among the best in the princes and even the entire country!"

King Qin was very confident, and even said: "The master said that I have talent, if I am not a prince, I can be the heir of mathematics!" ”

"Really?"

Fang Jue glanced up slightly, took chalk from the small box on the podium, turned around and wrote a binary equation on the rough blackboard.

"Come on, genius, you come up and solve it."

King Qin's eyes straightened, and when Fang Jue wrote the first character, he realized that he was about to be beaten again.

"What is this, sir...... Symbol? ”

King Qin wanted to say that ghosts draw talismans, but he was afraid of being beaten and reluctant, so he decisively changed his words.

Fang Jue said lightly: "Mathematics is unfathomable, this is just the entry level...... These symbols are also something you need to learn, if you don't have the talent to understand them yourself, why don't you let me explain them? ”

King Qin decisively admitted: "Please advise Mr.!" ”

He understands that he can't pretend in front of the teacher, otherwise the teacher will really not give face.

"Mathematics is the foundation of all paths, you have to learn more than you imagined, don't be proud of the things you have learned in the past, that is not real mathematics."

"Yes, Teacher!" King Qin was shocked, the teacher actually disdained Guozijian's mathematics department, if this was spread out, he was afraid that the master would come to the door.

"Then learn the first step...... Learn how to write numbers in a simple way, and this is also the homework you will go back to today. ”

Fang Jue felt that it was time to give King Qin a homework assignment.
