Gu Gaoxu said, "Brother Lu, don't tell me you've come up with another great idea?"
After a moment's thought, Lu Yuan said, "When people shell corn by hand, they can probably only get through a few hundred pounds of kernels a day at most."
Gu Gaoxu, who knew nothing about such things, said, "I suppose so."
Lu Yuan said, "Actually, I can create a device to help people shell corn."
Gu Gaochi, who was beside them, chimed in, "And what method might Lord Lu have to help people shell corn?"
Lu Yuan continued, "Crown Prince, you may not be aware, but shelling corn by hand is not only time-consuming and laborious, it's especially hard on the hands."
"These hired farmhands have been farming for years, and their hands are already chapped and cracked. I'm afraid even washing clothes and touching water must be agonizingly painful, especially in the biting cold of winter."
