Can y'all recommend me a novel where the MC teaches or trains one student or disciple? It's ok if he's weak or if he's OP.
World Teacher if you haven't already read it. Edit: Search the tag for Master-Disciple Relationship and you'll find almost every novel where MC teaches someone.
The MC didn't only train one student/disciple, so I don't see a problem with it? Nvm, you want a ONE student only.
I did that to emphasize the fact that I only want the MC to train One dude/grill. Not the other way around. Nvm, you corrected yourself.
