"Uncle Cheng? Cheng Yaojin…?"
Upon hearing the beautiful girl's words, Li Xuan immediately thought of a name.
This group of people were dressed in brocade clothes and had extraordinary auras. One of them even had a jade belt with a dragon carving around his waist. This was most likely the emperor. Other than him, no one dared to risk their lives to use such a thing.
As for the man called Uncle Cheng, he was ugly and had a stubble on his face. This immediately made him think of the current Duke Lu.
"What a pity!"
After guessing their identities, Li Xuan secretly regretted it.
If he had known that it was them, he would have extorted a huge sum of money. At the very least, he would have sold them for Yiguan money!
After all, there were no sweet potatoes in this world. No matter how expensive they were, these rich people were probably willing to spend money.
In this world, it was usually equivalent to one tael of silver. 1000 copper coins. If Yi Guan had given him one, he would have gotten five taels of silver.
"Delicious…!"
Princess Changle peeled it and took a bite. Her beautiful eyes couldn't help but light up. She wiped the sweet potato by her mouth and asked Li Xuan curiously,""What is this? Why haven't I eaten it before?"
"This is called sweet potato, also known as sweet potato. I imported it from overseas. Of course you haven't eaten it before!”
Li Xuan patted the dust off his hands and casually found an excuse.
In fact, including those morning peppers, they were all seeds that he exchanged from the system with achievement points.
Moreover, the ripening period was also greatly shortened. The sweet potatoes that originally took five to six months to grow could ripen in less than two months.
The morning sky peppers, which had a growth period of more than two months, could be harvested in a month!
"Sweet potatoes…?"
Princess Chang Le blinked her beautiful eyes and looked curiously at the green farmland.
He had just heard him say that sweet potatoes were planted in this field!
However, after looking for a long time, she did not see a single fruit!
"Are there any more? Can you sell me a few more? Money is not a problem!”
Seeing that the three of them were eating with relish, Zhangsun Wuji, who was hungry and greedy, asked amiably.
"There's no more. If you want to eat it, you can only dig it yourself!”
Li Xuan pointed at the sweet potatoes.
At the same time, he was secretly calculating how to use the sweet potatoes to earn his first bucket of gold after transmigrating.
"Dig…?"
Cheng Yaojin, who was a farmer, seemed to understand something. He opened the potato seedlings and saw that there were red roots in the cracked ridges.
He grabbed the thick roots and pulled hard. Three big sweet potatoes broke out of the ground.
"This is a sweet potato?"
Princess Chang Le looked at the string of sweet potatoes and immediately understood what was going on.
It turned out that this kind of crop ate roots and not fruits.
"Haha…these two are for you!”
Seeing the sweet potatoes on the ground, Cheng Yaojin threw the remaining two roasted sweet potatoes to Zhangsun Wuji and Wei Zheng. Then, he excitedly dug up the sweet potatoes.
It was the first time he had seen such a rare thing. He planned to bring it back for his wife and children to try.
Even if it was a hundred copper coins, he could still afford it.
"Mm, not bad! It's fragrant and sweet!"
Zhangsun Wuji and Wei Zheng tasted it and couldn't help but nod.
It was sweet but not too pungent, fragrant but not greasy. It could be said to be suitable for both young and old.
No one would have thought that the red lumps growing on the ground would be so delicious after being cooked in the charcoal fire.
"How many sweet potatoes are produced per mu?"
Unlike the four gluttons, Li Er thought about how to benefit the people.
Drought-resistant and delicious, this kind of crop was suitable for planting in Longxi. However, he did not know how much it could produce.
"About 4,000 to 6,000 jin!"
Li Xuan said after a rough calculation.
In fact, the yield per mu of sweet potatoes was 6,000 to 10,000 catties, but that was calculated at 10 taels per catty. In this world, 16 taels per catty, so he had to convert it in his heart.
"Four thousand to six thousand jin…?"
Li Eryi looked at him in shock, his eyes filled with disbelief.
At the same time, Zhangsun Wuji and Wei Zheng looked up as well. Their eyes widened as though they were looking at a monster.
Although they were the upper echelons, they still understood the most basic livelihood.
Since ancient times, even the most fertile farmland could only produce about 300 catties of grain per mu, but this sweet potato could reach more than 4,000 catties. How was this possible?
"Little child, don't spout nonsense. How can there be such a magical thing in this world? This is…"
Zhangsun Wuji wanted to say that this was the current emperor and he should be careful of deceiving the emperor. However, before he could finish his words, he was stopped by Li Er's gaze.
Helplessly, he could only swallow his words.
"If you don't believe me, then forget it!"
Li Xuan couldn't be bothered to explain. After all, he didn't plan on promoting it. He only planned on growing it himself.
If he planted too many people, he wouldn't be able to rip off these nobles.
"Alright, if the yield per mu can really reach 4,000 catties, I'll buy all the sweet potatoes in this field. However, there's a condition. You have to tell me the planting method!”
Li Er said excitedly when he saw his calm expression.
If what this kid said was true, then the people of the Great Tang would no longer have to worry about not having enough to eat!
In fact, not to mention four thousand catties per mu, even two thousand catties per mu was enough to solve the problem of food and clothing for the people of the Great Tang!
How could he not be excited about such a great thing?
"Not selling!"
To his surprise, not only did this kid not have the slightest intention, but he even rolled his eyes at him indifferently. This made him, who was still excited just now, choke for a moment.

I'm asking for flowers and reviews!
