I traveled through time and became a scholar from a poor family. My family was poor and I still owed three stones of millet to the Lord of Hell. Looking at my crying sister and the dilapidated thatched house with draft, I sighed. It's not just that I forgot high math, or I'm confused about chemistry, but as an engineering student, I still have the basic common sense. The first thing was to improve the stove so that my sister could have a hot meal. The second thing was to use lard and plant ash to make a rough soap to wash away all the dirt. When Zhang Yanwang came to collect debts, I drew a drawing of a waterwheel, and his eyes instantly brightened. "This, this thing can be used to offset your debt?" He asked with a trembling voice. I smiled slightly: "More than that. I want you to use three hundred acres of paddy fields to exchange for the next drawing."
