Madam, Your Character Is Ruined

After traveling through time and becoming an abandoned concubine in a cold palace, I decided to lie down and become a salted fish. He grows vegetables and raises chickens every day, and occasionally uses modern knowledge to deceive the little palace maid. Until that day, the tyrant kicked open the palace door: "My kingdom is about to perish. I heard that you are the chosen daughter?" I held the root of grass in my mouth and said, "Your Majesty, I'm just a waste." He narrowed his eyes: "Can soap, gunpowder, and penicillin be made from waste?" "... That's called daily tips." Later, I became the queen, and the tyrant stayed in my palace every night. "Honey, tell me any other tricks to conquer the world?"
