In Xiliu Township in the evening, you can see the smoke rising from the cooking stove in every village.

Of course, the Xie family is no exception, but tonight's Xie family's dinner is a little different from usual.

In the backyard of the house, Xie Xun and Xie Xiaoniang were surrounding a fire, listening to the 'crackling' explosion in the fire, and they could vaguely smell a fragrance.

"Big brother, when will the sweet potatoes you said be roasted?"

"Isn't the barbecue roasted over the fire? Why do sweet potatoes put under fire? ”

"Will it burn? If it's burnt, it won't taste good. ”

"Big brother, you have something to say."

Xie Xiaoniang was born with a curious baby attribute, and she was also outgoing and active, she just watched her eldest brother bury three or four sweet potatoes bigger than her palm in the firewood pile, and then told her that there would be good things to eat later.

Good stuff?

Do you mean that the red chunk?

It's a strange food, I've never seen it before.

The waiting time was the most boring, and Xie Xiaoniang couldn't bear it, so she could only mumble to Xie Xun from time to time, but unfortunately Xie Xun didn't know what he was thinking, and he didn't pay attention to his sister's question.

"Stinky big brother, bad big brother, the little lady is angry!"

Xie Xiaoniang was still muttering, but her little nose kept leaning towards the fire, and every time she moved forward, she took a hard breath.

Fragrant!

It smells so good!

Although she still doesn't know what the new food her eldest brother has gotten, with this fragrance, she feels that the taste must be no worse.

It's just a little troublesome, and I don't know how much to roast, and the eldest brother doesn't dare to stir the fire if she doesn't say it.

Xie Xun didn't speak, not deliberately ignoring Xiao Niang, but thinking about things related to sweet potatoes.

The appearance of sweet potatoes is an unknown crop reward given by the system after Xie Xun completes the mountain gate task (Village School Lishi). Just half an hour ago, he heard the system prompt to congratulate him on getting the 'sweet potato', and the whole person was stunned in surprise.

Then, Xie Xun fell into ecstasy!

There are many reasons for ecstasy, but the most important thing is naturally the sweet taste of sweet potatoes, and the yield of almost 10,000 catties per acre.

Especially when I see that the system gives itself a big bag of sweet potatoes. After estimating that there were not a hundred, but also eighty or ninety large sweet potatoes, Xie Xun waved his arms excitedly.

With so many sweet potatoes, if they are all planted in the ground, how much can be harvested in the coming year?

Conservative estimates, a thousand catties is not too much, right?

When a thousand catties of sweet potatoes are in hand, take out half of them and continue planting, how many will there be in the second year?

According to Xie Xun's estimate, it will at least exceed 10,000 catties!

To harvest 10,000 catties of sweet potatoes, the land area required for planting is likely to be no more than two or three acres, Xie Xun feels terrible when he thinks about it.

At the end of the Han Dynasty at this moment, even if it was a good year, how much rice per mu was produced?

A hundred pounds? Two hundred pounds?

If it reaches the sky, it will not exceed three hundred catties.

Three hundred and ten thousand, the two are not comparable at all.

Of course, these are Xie Xun's own conjectures, in fact, if he wants to turn this imagination into reality, Xie Xun knows very well that there is definitely a lot of trouble here.

The most regrettable thing is the season that Xie Xun crossed by himself.

It's the end of October, and it may not be long before the frost falls, followed by snow.

Sweet potatoes are not wheat, and as a typical tropical food of the Americas, they have absolutely no chance of surviving a winter in the field. Maybe it is possible to grow in Hainan, but Yanzhou is absolutely no play.

"Why didn't I come seven or eight months earlier?"

Looking at the bonfire in front of him, Xie Xun shook his head and sighed pity. Don't think about it this year, you can try to open up one or two acres of new fields around the surrounding mountains after the spring of next year.

"Plant 100 potatoes in the spring and harvest 10,000 catties of grain in the autumn."

"There is no idle land in the four seas, farmer, uh, bah, such an unlucky poem, don't read it."

There was a burst of complaints in his heart, but Xie Xun still inevitably thought of the vast uprising that could be called a textbook two years later.

"Two years is too short after all."

"If I can come to the end of the Han Dynasty a year or two earlier, with the sweet potatoes in my hand, after three or five years of promotion, I can definitely reach an annual output of one million catties."

"It's a pity that history has no ifs, and this catastrophe at the end of the Han Dynasty can't be eliminated by food alone. It would be good if he could protect Xiaoniang and his Huaxia University in the troubled times in the future. ”

I went through all the nonsense thoughts in my head, and finally turned into a sigh. When Xie Xun came back to his senses with a low sigh, he just smelled a strong potato fragrance.

"Alright."

As soon as his eyes lit up, Xie Xun picked up a big wooden stick and pushed the fire away.

Pull it twice, and soon a few black bump-like things rolled out of the fire pit.

"Big brother, it's like this when the sweet potato is baked?"

Looking at the black bump that rolled to her heels, Xie Xiaoniang's eyelids jumped. Although the fragrance is still so strong, the appearance of sweet potatoes is too unbearable.

Can you eat it?

Xie Xiaoniang expressed 10,000 doubts!

"Whew~ It's still a little hot."

Reaching out and touching the black bumps on the ground, Xie Xun stretched out his sleeves, directly wrapped a big sweet potato around the cuffs, and tore the burnt skin on the outside with his left hand, immediately revealing a piece of golden red.

"Wow~ This is a sweet potato."

Seeing the gorgeous transformation of sweet potatoes, Qiongbi immediately leaned over, knowing that her sister was a snack, Xie Xun tore off a piece of it funny, and motioned for Xiao Niang to open her mouth.

"Ah~hmm~hiss~ hot, hot, good, fragrant, delicious."

With a piece of fragrant sweet potato in her mouth, Xie Xiaoniang's whole face is comparable to everyone who has studied Sichuan opera for ten years. It was very hot, but he refused to spit it out, but he had to swallow it in his stomach, and Xie Xun, who saw it, laughed.

"Big brother villain, look at the little lady's joke!" Finally took a bite, Xie Xiaoniang puffed up her bun face again, and then turned her head, indicating that she didn't want to pay attention to Xie Xun.

The little lady was arrogant again, Xie Xun didn't pay attention to it, anyway, there were several sweet potatoes on the ground, and the little lady didn't need him to feed them all the time, so she blew on herself and started to eat sweet potatoes.

Sweet and delicious, it is absolutely 10,000 times better than any bread!

Four or five big sweet potatoes, two brothers and sisters ate separately, less than half an hour has eaten the essence, the first time to eat the sweet potato of the little lady is still unfinished, but unfortunately the fire has been extinguished, and it is even more empty.

"Little lady still wants to eat?" Xie Xiaoniang's thoughts, how could Xie Xun not see it.

"Hmm."

"It's not going to work this year, wait for next year, in another year, Xiaoniang will be able to have sweet potatoes that you can't eat every day, and then let you eat enough, until you don't want to eat anymore."

"Big brother is deceiving again, how can you not want to eat such a delicious sweet potato, and you won't get tired of having a few more little girls."

"Haha~ That's what you said, let you eat sweet potatoes every day next fall."

"Okay, okay, do you want to wait until autumn to have sweet potatoes to eat?"

In the bottom of my mother's heart, I have never eaten food more flavorful than sweet potatoes in my life.

Can you eat sweet potatoes every day?

Then I'm going to be so happy.

Looking at his sister's distracted eyes, Xie Xun shook his head with a smile, but a flash of hope flashed in his eyes.

Sweet potatoes are already available, but are other crops still far away?
