A Little Reunion: I Transmigrated into a Book with a System and Tamed the Worst Class

After staying up all night and dying suddenly, teacher-training student Chu Fei transmigrates into a book and becomes the homeroom teacher of Class 12, Grade 12, at Chunfeng High School. He takes charge of the 35 most troublesome students in the entire grade. After activating the Devil Teacher System, he confiscates phones, wields a pointer, and drags students to the edge of the roof to establish his authority. He can even exchange points for talents to improve his students, and swears to turn his worst-performing class around within a year.
