Three Kingdoms: At the beginning, Cao Cao Sangu Maolu invited me out of the mountain

In fact, Shen Xuan blamed them wrongly.

For the understanding of the Three Kingdoms, he is still at the level of interpretation.

He knew almost nothing about agriculture, economy, etc. during the Three Kingdoms period.

Where does he know.

In the past, rural hometowns, even if it was a very common thing.

In the Three Kingdoms period, it was an out-and-out black technology.

In the eyes of Cao Cao and others, it was naturally shocking.

“There are still things in the field, please take care of yourself, and come over later to accompany you!”

Shen Xuan said to Cao Cao and the others, and then went to the ground.

Today’s sweet potato excavation, Shen Xuan is a little uneasy, must personally guard.

Cao Cao squinted his eyes and stared at Shen Xuan’s back.

Xun Yu lowered his voice: “This person’s means are unfathomable, such a wizard, no matter the cost, he must be used by the Lord and the public!” ”

Guo Jia shook his head and said, “I see that this person has an unruly temperament, and may not be willing to do things for the lord!” ”

“If he dares not obey, he would rather kill him than fall into the hands of others!”

Cao Cao said in a deep voice, with killing intent.

The domineering and majestic majesty of a generation of heroes are on full display at this moment.

Guo Jia’s lips moved, and he stopped talking.

The unfathomable Mr. Shen does not know how many powerful means he has.

If you really want to kill him, how can it be so easy?

At that time, I am afraid that I will not be able to kill him.

Perhaps, it will cause big trouble!

“Go, go to the field!”

Cao Cao brought a few people to the field.

Shen Xuan was working with a dozen peasants.

The crops in the field are strange.

Cao Cao and others had never seen or heard of it.

Several people were surprised again.

Guo Jia asked, “What kind of crop is this?” ”

“Sweet potatoes.”

Shen Xuan brought over a lot of ingredients, including five sweet potatoes.

He used these sweet potatoes as seeds, and after two seasons of cultivation, it has now grown to more than an acre.

“What is a sweet potato?”

“Don’t even know about sweet potatoes? Sweet potatoes are a kind of grain that can be used as a staple food or fed to pigs, horses, cattle and sheep. ”

……

Shen Xuan was a little annoyed, and he really didn’t want to pay attention to these sand sculptures.

These people should not be stupid.

But the limbs are not diligent, and the grains are not divided.

Dian Wei said angrily: “This thing is dug out of the ground, can it also be eaten?” Although your brain is not good, you can’t use this to deceive you! ”

“Of course you can eat it!”

“I’ll give you a taste, clean it up, and eat it raw!”

Shen Xuan threw two sweet potatoes to Dian Wei.

Dian Wei took the sweet potatoes and went to the river to wash them with the river water.

Click!

Dian Wei opened his mouth and bit off a sweet potato in half.

He’s not hungry.

Who knows if sweet potatoes are poisonous?

Testing poison for Cao Cao was his duty.

Cao Cao and the others all looked at Dian Wei intently.

Dian Wei was stunned there.

Xun Yu couldn’t help but ask, “Junming, how?” ”

“Well, delicious!”

“The taste of this fruit is really good!”

Dian Wei praised loudly and ate all a sweet potato in a few bites.

Fruit?

Shen Xuan shook his head and smiled.

Whose fruit grows in the ground?

“Bring it, let me taste it!”

Looking at Dian Wei’s eating appearance, Cao Cao also moved his index finger.

Dian Wei took out a knife, peeled the sweet potato, and handed it to Cao Cao.

Cao Cao took a small bite.

Fragrant, sweet and crispy!

What a fragrance!

Cao Cao nodded repeatedly, “This is a sweet potato?” How does it feel like fruit? ”

Guo Jiadao: “There are even fruits born underground, the big world, it’s really amazing!” ”

Shen Xuan was amused, “Sweet potatoes are not fruits, not only can they be eaten raw, but they can also be cooked and eaten, if sweet potatoes are mixed in rice porridge, they can be used as staple food!” ”

Not only quench thirst, but also serve as a staple food?!

Cao Cao and Xun Yu’s eyes suddenly lit up.

“Sweet potatoes can not only be eaten raw, but also roasted, steamed, boiled, or dried, and left for two or three years.”

“Sweet potato leaves can be used as a vegetable or as a feed to livestock.”

“Drying the leaves and vines of sweet potatoes can also be used as feed, mixed with black beans, and even used to feed war horses.”

Shen Xuan continued to popularize science to several people.

“Are sweet potatoes easy to grow?”

“How much sweet potatoes are produced?”

Cao Cao and Xun Yu asked urgently.

They have realized the importance of sweet potatoes and are breathing rapidly.

“Sweet potatoes are easy to survive, barren slopes can be planted, as for acre yield…”

Shen Xuan calculated in his heart.

“Probably, there should be four or five thousand catties!”

Shen Xuan remembered that the yield of sweet potatoes in the countryside seemed to be so high.

“Four or five hundred catties per acre?”

“Twice as much as wheat?”

Cao Cao was taken aback.

He was clearly mistaken.

It’s not that his ears are bad.

But people in this era can’t imagine that there will be thousands of catties of grain per acre.

You know, the current mu yield of wheat, can have three hundred catties, it is already a super high yield.

Shen Xuan corrected: “It’s four or five thousand catties!” ”

“How much?”

Cao Cao’s eyes were as wide as copper bells.

Xun Yu and Guo Jia were also full of incredulity.

Shen Xuan said: “Four or five thousand catties, why are you not old, your ears are not good?” ”

Cao Cao opened his mouth wide, but he couldn’t slow down for a while.

Xun Yu and Guo Jia gasped.

Dian Wei was stunned, his head was not good, let the wrench count.
