Sweet potatoes, in addition to raw potatoes can be brought for a month or two, cooked is absolutely impossible.

So the old woman's idea for Yu Shu was that they still had some raw ones at home, so they could sell them to Yu Shu cheaper, and when they wanted to eat them, they could bake a few by themselves.

"Really? Grandma, do you grow a lot of it at home? Can you still sell it to me? ”

When it came to biology, Yu Shu immediately recalled in his mind that the roasted sweet potatoes in the northeast were quite delicious.

If you can get some, go over there and plant a wasteland......

"There aren't many, it's a few that my son inadvertently got before, and I didn't know how to eat it at that time, so I threw it there, I saw it sprout and planted it casually, and it turned out to be some, and there was actually only fifty or sixty catties left in the family."

The old woman said, hanging her head a little embarrassed, but she said more.

Including herself, she didn't know how to eat this sweet potato, but she was reluctant to throw it when she saw that it had a lot of fruits, so she collected it and threw it in the cellar****** potatoes have roots, and naturally there are vines, and she cut the young leaves of the vines and fed them to the pigs, and the old vines were dried and burned as firewood.

It was the time of the fire, and the fragrance of some small sweet potatoes fell on the old vine, which gave her the idea of roasting sweet potatoes.

“……”

Yu Shu looked at the old woman's kind and simple face, and couldn't help but sigh secretly in his heart.

Sure enough, the invention comes from life, who would have thought that an illiterate old woman could discover the deliciousness of sweet potatoes by doing it at will.

"Then grandma, do you want to sell those sweet potatoes?"

Knowing that sweet potatoes are not only roasted to eat delicious Yu Shu, but when I heard that sweet potatoes here are not available everywhere, I was even more determined to plant sweet potatoes.

It's just that the old woman is only so sweet potato after all, and she doesn't know how much she can take away.

"Sell...... Why not sell it! I just want to keep a dozen catties as seeds, others can't recognize the goodness of this thing, I can't sell it even if I want to plant it. ”

When Yu Shu heard this, he couldn't help but be overjoyed, "Then grandma, can you sell me the rest?" ”

Fifty or sixty pounds? Buy it all?

Chu Yu frowned, and couldn't help but pull Yu Shu aside.

"Shu'er, if you like to eat, you can buy some, but you don't need more than fifty catties, there are still more places we have to pass along the way......"

"I don't know what will happen after that, but this thing must be bought! Chu Yu, don't you want everyone in the deserted city to have enough to eat? Buy this thing back, I have a way to make everyone have enough to eat. "It's just that it's going to take a while, after all, there are still too few sweet potato seeds.

Chu Yu turned his head and looked at the black thing, a little incredulous.

"That thing, can it really make people full? Book, which book did you read it from, didn't you remember it wrong? ”

Although he is not a full reader of poetry and books, he is also a person who has read many books, and he has never seen a book with such a thing as sweet potatoes.

"If you don't believe it, I can't either, but I must buy these sweet potatoes, and if you don't want to, I can also pay for it myself."

"But this is a long way, I am afraid of ......"

Before Chu Yu finished speaking, Yu Shu's clothes were grabbed by the old woman.

"Girl, this sweet potato is really a good thing, but others are not as knowledgeable as you. Since you want it all, then my wife is not a stingy person, if you go with me immediately, I will sell it to you for three cents and two catties! Do you want it? ”
