Azure Files: the Strongest Sensei

The products produced by Brother Man must be high-quality products! When the original teacher was dead and no one knew, a volunteer picked up the Shiting Box and bound his fingerprints to the Shiting Box again. Becoming a new teacher, he embarked on a path different from others! Ps: You must read the introduction of this fan work, otherwise you will not know how the protagonist became a teacher. At the same time, this is Brother Man's first time creating a work, so please give me your advice!
