The Strongest Teacher: I Become an All-Rounder in the Instance World

In the Wild West, he is a sharpshooter;

In the world of assassins, he is the King of Assassins;

In the savage wilderness, he is the guardian deity of a tribe;

In Middle-earth, he is the strongest warrior of the human race...

But in the real world, he is an ordinary homeroom teacher at Luonan Elite High School, whose class is full of little troublemakers.
