I Really Am a Good Teacher

Legend has it that after death, everyone goes to the underworld, where they wash away their sins and begin their next life... But no one knows that the underworld isn't a place at all. It's a person, someone who has lived for countless ages! Whatever you did in life, after death you'll be digging for ore! I'm the big shot of the underworld, and I love teaching and guiding others! I know your past and present lives, so I'll tailor my lessons just for you! Reincarnated Li Bai: Teacher, I really can't memorize any more! Every time this guy drinks, he writes poetry. How am I supposed to memorize all of it? Reincarnated Lu Xun: Teacher, I honestly don't know why he planted two jujube trees in front of his house! Ying Zheng: Sir, I know I was wrong. I shouldn't have led an army down here to rebel back then. Look, I've been mining for so many years. Could I go reincarnate now?
