Wasn't that a bunch of green plants that Xiaoying and the others had overlooked sweet potato seedlings?
If there were a sweet potato plant, there would be sweet potatoes. Su Qing pulled up the sweet potato plant; sure enough, a string of red sweet potatoes was at the bottom. The thick ones were about the size of a wrist, and the thin ones were about the size of a finger. They could be used as food.
"Everyone, come here. Do you see this? You should pick it."
Su Qing showed everyone the sweet potato seedlings and sweet potatoes. They grew sorghum, chestnut rice, other grains, and leafy vegetables. It was Ji Xiaoying's first time seeing sweet potatoes.
"Sister, can this be eaten?"
"Yes, and it's very delicious."
Su Qing saw that Xiaoying didn't recognize sweet potatoes, so she guessed that no one knew that sweet potatoes were edible crops in this era.
