Upon hearing Aunt Zhang's words, Er Yue slowly raised her head, her expression somewhat unnatural.

"No, I was worried that if I walked too fast, I might trip and fall and break this."

As she spoke, she carefully held up the hairpin she had been holding in her hand and presented it to Aunt Zhang. Only then did Aunt Zhang notice that Er Yue's hands were covered in sweat.

"Oh, you silly child, how about I help you carry it..."

"Alright, Mother, take care of those things, I'll help you walk!"

Seeing how nervous Eryue was, Aunt Zhang also became nervous. As a result, what should have been a journey that took only an incense stick's time turned into a journey that took the two of them almost half an hour.

The next day, when everyone heard that Han Yiyi was going to harvest sweet potatoes, they all rushed over early in the morning, eager to see what this thing they had been longing for looked like and whether it was edible.

Actually, Han Yiyi had told everyone before that in addition to the sweet potatoes at the bottom being edible, the leaves and stems at the top are also edible.

These days, the wild vegetables on the mountain haven't grown as fast as everyone's eating them, and now they're all bare. So everyone's eyes have turned to these sweet potato leaves. Now that I think about it, only Han Yi's family's sweet potato leaves are still intact.

Because of the sweet potatoes planted by Han Yi's family, she went to Kyoto and hardly took care of them. Now, looking at their roots, they are not very thick, so the sweet potatoes below should not be very big. But when the first one was dug out, not only everyone else, but even Han Yi was stunned.

On one stem, there were five or six sweet potatoes, each one big and long. Judging from their appearance, each one should weigh about three or four pounds. So, one stem can produce about twenty pounds of sweet potatoes.

Everyone was stunned by what they saw. Someone even swallowed hard before they came to their senses.

Because everyone was worried that digging them up too early would damage the sweet potatoes, they refrained from digging them up, no matter how hungry they were, and only ate the leaves and stems. So, this is the first time that everyone in Dajia has ever seen sweet potatoes.

“Yi-yi, this, this is the sweet potato you were talking about. This one plant can produce so many. Then, how many kilograms would this acre of land weigh…”

The village chief's voice trembled slightly as he looked at the sweet potato in Han Yiyi's hand.

Hearing the village chief's words, Han Yi thought for a moment. When they asked everyone to plant, they planted 3,000 plants per mu (unit of land area). Each plant could produce 20 jin (unit of weight) of sweet potatoes, so one mu would yield 60,000 jin of sweet potatoes.

Han Yiyi was startled by the number she had calculated. She knew that in modern times, the yield of sweet potatoes in some places was only around seven or eight thousand to ten thousand catties.

The yield here is so high, could it be because the sweet potato seedlings are produced by the system? Thinking that perhaps not every plant will produce so many, Han Yiyi dug up another one.

Sure enough, this time there were significantly fewer fruits than the previous one; there were only two larger ones, which looked to weigh about four or five pounds.

Seeing this, Han Yiyi dug up two more. Sure enough, some were big and some were small, and some were plentiful and some were scarce. Han Yiyi made a rough estimate before speaking.

"There are big ones and small ones. Judging from the size, one mu of land should yield about 6,000 jin, but we need to dig them all out to see for sure."

As soon as Han Yiyi finished speaking, she heard gasps and swallowing sounds from everyone around her.

When Han Yiyi first said that one mu of land could yield 5,000 jin, everyone was already somewhat incredulous. They never expected that it would yield even more than 5,000 jin now.

"Indeed, it's a gift from the gods. With this sweet potato, we... we'll never have to go hungry again," someone exclaimed upon hearing Han Yiyi's words. He then knelt down, kowtowed, and murmured something.

"Thank you, God, thank you, God..."

Seeing one person do this, the others immediately followed suit and began to kowtow.

Only then did Han Yiyi remember that she had said the sweet potato seedlings were a gift from a deity in order to avoid revealing her system.

A hint of unease flashed across his face; should he kneel or not?

However, remembering that Han Yiyi had previously stated that in order to promote the sweet potatoes, each family should keep some sweet potatoes as seeds for promotion, she spoke up.

"Everyone, get up quickly. I think the gods have already felt your sincerity. But don't forget what you promised the gods: each family should contribute some sweet potatoes as seeds to spread throughout Beichen. That way, none of the people of Beichen will go hungry..."

"Yes, yes, yes, we'll pay, we'll pay..."

“Yes, Han girl, whatever you say, we’ll pay…”

Hearing what everyone was saying, Han Yi realized that this promotion couldn't be accomplished overnight, so he spoke up.

“Then let’s give each family 100 jin. But there’s no rush. After everyone has dug up all the sweet potatoes, we can give the 100 jin we’re using as seeds to the village chief, who will then give them to the town supervisor to promote them.”

Upon hearing Han Yiyi's words, everyone nodded in agreement, but one person still asked a question.

"Han girl, it's not even October yet. Even if you plant rice, you'll have to wait until next year. So, can we just let the sweet potatoes in the field grow like this? We can just dig them up when we want to eat them and let them grow a little longer. Wouldn't that make them grow even bigger?"

Hearing this, the others all looked at Han Yiyi, because they also wanted to ask the same question: eating and digging at the same time, with an endless supply of food in the ground, it sounded wonderful.

"If you don't want to dig now, you can wait, but it's best to dig them all out before the end of October, otherwise they'll freeze when it gets cold..."

"Oh? They're frozen. If we dig them all out, where are we going to put them...?"

Hearing Han Yiyi say that the grain would freeze, everyone was shocked. So much grain would be wasted if it froze. Even the village chief asked anxiously.

"Yes, Han girl, if we dig all of these out, what will we do with them when it snows? Do you have any good storage methods...?"

Now, everyone is worried about the excessive production.

Seeing the anxiety on everyone's faces, Han Yiyi quickly spoke up.

"Don't worry, just dig a cellar and put them in. Of course, you can also cut them into slices and dry them for storage, or you can make some sweet potato flour to store. These methods can also be used to store them for a long time."
