I Work as a Nanny in Corpse Dynasty

"You claim to be immortal, but you lock your knowledge in rote memorization of words. You are so pitifully stupid!" Facing the high-ranking ladder sequencers and the famous teachers of the Nanny Guild, I casually drew a pulley set and a petri dish on the ground. They cut off my food and wanted to see me and the eight cubs starve to death in the bottom layer without soil. But they don't know that in my mind, a "short-lived insect", I have five thousand years of civilization. When my students used physics to instantly kill martial arts masters and used biology to grow sky-high-priced vegetables, those immortals who once laughed at me all knelt down and begged me to accept their children.
