C17 (1/2)

Changjian led Mr. Xue through the alley and stopped in front of an arched door.

Changjian went up and said a few words to the guard. The guard went in to report, and soon, someone came to lead Mr. Xue in. Changjian was waiting for him.

She followed the guard into the same room as yesterday. Other than the maids and attendants, only Lady Liu accompanied her.

Today, the two ladies were both wearing a dress. Princess was dressed in black silk with complicated yet elegant patterns on the satin. She looked extremely beautiful.

Lady Liu wore a light blue dress with white hem. Fluttering butterflies were embroidered on the corner of her dress. It matched well with her beautiful eyebrows and beautiful eyes, making her look very elegant.

The two of them were sitting at the same spot; it was really beautiful.

Seeing Mr. Xue enter dressed in an old-fashioned suit, Princess's eyes narrowed. She didn't change her expression: ”Youyang, what are you here for?”

Mr. Xue followed the maid's lead and sat down in front of Princess Pingyang. He placed the box he was carrying on the table and smiled: ”Just now, I was packing a few things. I think that Your Highness Yu should be able to use them.”

Hearing Mr. Xue's words, Princess Pingyang showed a little interest on her face, ”What is it? Did you bring it from the Fowler? ”

Mr. Xue nodded and asked: ”May I ask Your Highness, have you heard of sweet potato and potato, these two crops?”

Princess Pingyang shook her head. ”Never heard of it. What is it? ”

Mr. Xue did not answer, but continued to ask: ”May I ask, with your Highness' current Tang Dynasty, how much food can be produced per acre of land?”

Princess Pingyang's eyes lit up, ”In Guan Zhong, the yield of a superior good field can reach three stones per mu. If it is such a barren land, the yield per mu would be lower.”

Three Stones... One stone was equal to ten fights, each battle weighed around ten jins. In other words, the yield of a good field was only around three hundred jins.

As expected, without fertilizer or scientific methods of farming, the food production was extremely low. In addition to all kinds of taxes, there were not many people who could eat their fill. No wonder the people of ancient times had almost no ability to resist disasters. In the final analysis, it was still the food production that was too low.

Mr. Xue made up his mind. He didn't keep any suspense and directly opened the box. He handed the box to the maid: ”Please have a look, Your Highness!”

The box contained two sweet potatoes, a potato, a handful of peanuts and a handful of pinch of pumpkin seeds.

Princess Pingyang took the box from the maid and asked with a strange light in her eyes, ”What is this? Can you eat it? ”

This question gave Mr. Xue a sense of familiarity.

Indeed, you are worthy of being a citizen of my gluttonous country. When you see something, the first thing you care about is whether it can be eaten or not.

Mr. Xue saluted, stood up, and pointed to the contents of the box: ”This thing is called sweet potato, also known as Gan Gang, Hong Fu, it has the function of nourishing the deficiency, strengthening the spleen and stomach, strengthening the kidney and yin, it can also be used as food, or as vegetable, it has the characteristics of high and stable production, resistance to drought, low insect pests and other diseases, is easy to plant, easy to store, and produces 1000 kg per mu, which is more than 10 stones! If you can keep up with the fat stuff, the highest you can produce is about twenty stones. ”

”Pfft ~”

This was the water that came out of Lady Liu's mouth when she was shocked!

Princess Pingyang was indeed a black-skinned person, she was able to keep her composure. If Mr. Xue hadn't been paying attention to her, he wouldn't have noticed her hand suddenly clench before releasing her grip. She still maintained a calm expression and took a sip of water calmly.

Your Royal Highness, your qi recovery skills are so great, does your father know about this?
