Ming Dynasty: I Built a Steam Engine, but My Old Ministers Called Me Witchcraft

My head felt like someone had stuffed it into a pressure cooker, and my ears were filled with buzzing noises. No, it's not a pressure cooker, it's someone quarreling. I tried to open my eyelids, but the bright yellow in my vision made my eyes hurt. The yellow ones are curtains and the yellow ones are dragon robes. I looked down and saw that I was also wearing bright yellow - these were not work clothes but dragon robes. Etc. Dragon robe?
