After dinner, Aunt Zhang and Madam Xu dumped the cassava from their bamboo baskets onto the ground. As they were reaching for Shen Wanning's basket, they saw the sweet potato vines inside.

"Hey, Wan Ning, what kind of wild vegetable is this? Why have I never seen it before?" Aunt Zhang took out a sweet potato vine and asked curiously.

I was so focused on the ginseng that I almost forgot about the sweet potatoes.

Shen Wanning walked over with a smile, "Mom, this is called a sweet potato vine. When you plant it, it will produce sweet potatoes, which are similar to cassava. But sweet potatoes are non-toxic and can be eaten raw, steamed, or boiled. They taste even better than cassava!"

"There is such a magical plant? But why have I never heard of this plant before?" Aunt Zhang looked at the sweet potato vine curiously, but couldn't see anything special about it.

"Yes, these sweet potatoes are not only delicious, but also have a very high yield! It's just that I discovered these sweet potato vines by accident, and there are not many of them, so I pulled them all back. When the sweet potato vines grow more in the future, if the villagers are willing, they can come to our house to cut some sweet potato vines and take them back to plant." Shen Wanning continued to explain.

Lin Jingyou didn't go back to his room after dinner. He sat in the yard and listened to them talking.

Although he had been studying since childhood, he was familiar with crops. He had never heard of sweet potatoes, let alone seen them in books. He didn't know which book Shen Wanning had read about them.

"Sister Wan Ning, excuse me for asking, but have you seen this sweet potato in a book? I have never read such books before, so I wonder if you still remember which book it was?" Thinking this in his mind, Lin Jingyou asked casually.

"Third brother, I really don't remember this. Third brother, you also know that when I came to Daqing Village, I had forgotten everything before. Even this knowledge is all in my head, and I don't know how I know all this."

Shen Wanning made up an excuse, and luckily it wasn't bad, so Lin Jingyou believed it without giving it much thought. However, he became even more curious about Shen Wanning's identity.

Aunt Zhang shook the sweet potato vine in her hand. "So can we just bury it directly in the soil? Planting it directly with the vine like this is really rare!"

Shen Wanning watched the popular science information given by netizens in the live broadcast room. She carefully memorized the method of grafting sweet potato vines and told it to Aunt Zhang.

"Yes, if we plant these sweet potato vines now, they will be mature in September. If the villagers plant them later, they will probably not be mature until October."

"Oh my god, it takes so long! The wastewater from this house has to be used to irrigate the fields, which is not enough! Not many seedlings will survive! Besides, although cassava has a high yield, it needs to be soaked in water, and water is needed everywhere." Aunt Zhang sighed, still a little worried.

"Mom, I do have a suggestion, but I'm afraid it's not easy to do."

"Sister Wan Ning, feel free to speak up if you want to. Let's pool our wisdom. If it can benefit everyone, no matter how difficult it is, we will find a way to do our best." Lin Jingyou stared into Shen Wan Ning's eyes, his eyes full of trust.

"Mom, I just said that these sweet potatoes have a very high yield. Do you know how much they can produce? Our rice yield is about 300 kilograms per mu, but these sweet potatoes can produce up to 3,000 kilograms per mu! That's ten times more than rice!"

In fact, the per-acre yield of modern sweet potatoes is generally between 5,000 and 7,000 kilograms, but because of the different land, and Shen Wanning cannot guarantee that these farmers can take good care of these sweet potatoes, the yield is still much lower.

"What? What did you say? Three thousand kilograms? Wan Ning, you are kidding me! Even cassava doesn't have this much yield, so how can sweet potatoes have such a high yield? No, no, you must have remembered it wrong, or the book is wrong."

Aunt Zhang happened to be sitting on the three-legged chair and she was so scared that she fell to the ground. Lin Jingyou quickly helped her up, and Aunt Zhang sat on the chair and shook her head.

"Yes, Wan Ning, what you learn from books is always shallow. Such a high yield has never happened in our Great Xia Dynasty. I'm afraid you can't believe everything in the book." Lin Jingyou also agreed with Aunt Zhang's words. After all, a yield of 3,000 kilograms per mu sounded too incredible.

"We have been dealing with the land all our lives, Wan Ning! You have to listen to us on this matter. It is impossible to produce 3,000 kilograms per mu. If that were the case, there would be no one dying from famine in our Great Xia Dynasty!" Lin Dashan followed.

The other members of the Lin family nodded, completely unconvinced about the sweet potato yield.

Shen Wanning spread her hands helplessly, "That's why I said this matter might be difficult to handle. Even you don't believe it, let alone other people.

Sweet potatoes not only have a high yield, but also prefer drought conditions, requiring much less water to grow than rice. If we can plant one acre of sweet potatoes, the normal wastewater can fully meet the sweet potato's water needs.

I originally suggested that since the survival rate of rice seedlings was so low, we should abandon rice cultivation this year and plant sweet potatoes instead. These sweet potatoes can also be used as a staple food to fill our stomachs.

If it rains again, we can plant mid-season or late-season rice. At least we have sweet potatoes to meet our basic needs. Until the sweet potatoes ripen, the old grains in every household, plus cassava, will be enough to tide us over for a while."

Shen Wanning chattered on and on, saying such a long paragraph, just to persuade them.

Although everyone didn't believe in the sweet potato yield, after Shen Wanning's analysis, Lin Jingyou started to think.

"Let's put it this way, Mom and Dad. Since Sister Wan Ning said these sweet potatoes are edible, let's plant these sweet potato vines first. These sweet potato vines don't need much water, after all.

As time went on and the sweet potato vines grew taller, we told the other villagers about the sweet potatoes. We didn't want to say too much about the yield, just about 500 kilograms! That way, the villagers would be more convinced.

Whether they believe this and plant sweet potatoes is up to them. We can only do our best and leave the rest to fate. At least now that we have cassava, no one in our village will go hungry.

"What my third brother said makes sense. Even we in the Lin family don't believe what Sister Wan Ning said about the sweet potato yield, let alone other people. Let's just say it's around 500 kilograms. After all, they are neighbors, and it will always be right for us to persuade them to plant more." Lin Jingcheng agreed.

Aunt Zhang hardened her heart and slammed the table. "Forget it. I believe Wan Ning is a blessed woman. She will never harm us. From today on, we will plant sweet potatoes. From now on, the wastewater will be used to irrigate the sweet potatoes first, and the excess will be used to water the seedlings."
