[No personal heroism, no intelligence, urban] Jiang Xiao, a college student who had a headache with internships and papers, woke up from a sleep and came to a different world. Jiang Xiao: No, why can he become a knight if he likes it? Why can the tomb guard control the corpse? I really want to go home. Friend: No, how did my cold friend turn into a funny guy? Why does my little brother like him more? Parents: Where is our wonderful son? Teacher: Why do I feel like my good student has become stupid? Enemy: Didn't you say that he is the protagonist? Why does he look like a roadside guy? Jiang Xiao: Look at my ability to pretend to be sweet.
