"Yes."

Ying Xuyan had already thought of a rhetoric, and immediately ordered someone to break off a corn cob and come over.

She personally tore the outer skin and pointed to the golden corn kernels to show Brother Zheng: "Father, you see, this is the corn kernel, dry it and grind it into flour." ”

"You can also roast it like this and eat it, or cook it with water."

"There is also this corn cob inside, which can not only be used as firewood to cook rice, but also used as medicine."

Speaking of medicine, Ying Xuyan hurriedly looked at Xia Wuhe: "By the way, Lord Xia, this beard is also a good thing that can be used for medicine, you can get some to try." ”

"Really?"

As soon as Xia Wuhe heard this, he came to his senses, "Please also ask the princess to teach me." ”

"I've also heard from others about this, and its specific role still needs to be studied slowly by you doctors."

Ying Xuyan didn't say anything to death, but she also provided him with ideas, "I only know that this must cure kidney and bile diseases, and also stop diarrhea; ”

"This corn cob has more functions, it can not only treat kidney, liver, gallbladder and other diseases, but also can be used in many places in daily life."

"I hope that Xia Wuji will develop and research more."

"This ...... This and this ......"

Hearing Ying Xuan say this, Xia Wuhe trembled with excitement, "Then, then please let the old man collect all these things, okay?" ”

Yingxuyan: "The boss doesn't need to worry, as long as there are people planting it every year in the future, this beard and core are indispensable." ”

"But now you can collect some and test them if you need them."

"You'll have to keep some of this cob for me, though, and I'd like to see if it does anything else."

"Alas, good, good, good."

Xia Wuhe was excited, and looked at Ying Zheng again: "Please ask Your Majesty to allow the old minister to get some corn silk and corn cobs from Her Royal Highness the princess." ”

"Since Hua Zhang has promised you, you can just watch and collect."

Ying Zheng listened to the conversation between the two, his eyes flashed with joy, and his charming gaze fell on his daughter, "I don't know where Xu'er learned this?" ”

"Also, where do these seeds come from?"

She was prepared, and hurriedly replied:

"A few months ago, Erchen, Brother Gao, and Brother Jiang Lu went out of the city to play, and they exchanged them from an old farmer."

When Ying Zheng heard this, his face did not show the slightest joy, but became a little serious: "Old farmer? ”

"Mmmm, he said that he was a farmer, but he didn't have any land to plant."

Knowing that Zu Long would not believe it easily, Ying Xu Yan had already prepared for this day, no matter what Zu Long asked, she had a reason.

"At that time, the retainers saw that he was very hungry, and took out a black thing from a pile of ashes and came out to eat."

"I was frightened, and fearing that he would eat it, so I gave him the pastry I had brought out, and she invited me to eat this black thing."

……

Under Ying Xuyan's narration, it was she who followed the royal brothers out of the city to play, and accidentally met an old man who was hungry and thin.

The other party was pulling out the black pimple from the ashes to eat, and she stepped forward to stop it and deliver the pastry, but the old farmer smiled and gave the black pimple to her.

She shook her head and refused to eat.

Then the old farmer carefully peeled off the black skin on the outside, and the inside was actually yellow flesh, and there was a sweet smell coming out, and he wanted to eat it when he smelled it.

The two exchanged foods, and then learned from each other that he had a lot of high-yielding grain from other countries, but unfortunately there was no place to grow it.

So she used the money and pastries on her body to exchange the remaining seeds in her pocket with the other party, and when she came back, she quietly planted them in the Cuiwei Palace.
