What's the scariest thing about teaching students? At first, he thought it was teaching a lovesick student who'd use him to smash through walls.
Later, he realized something even more frightening: getting hounded by a group of students of unknown origins. Some could fly on swords and astonish the world with their swordsmanship; some could heal the dying and raise the dead; others wielded strange flames capable of moving mountains and taming seas...
Worst of all, these students were lusting after his body! And he couldn't even beat them! All he wanted was to farm in peace and enjoy his retirement!
"Master, what are you thinking?" He suspected he might have been a pervert in his previous life. Otherwise, why would he always pick pretty, adorable students?
