Blind Master: Raising Monster Prodigies

The students at Adrian Leigh's school are mountain spirits. Adrian is blind and has them down as village children from the hills nearby. He came into this world from another time, and a system called the Ultimate Master-Teacher System came with him. It sets him tasks, and finishing them is the condition on getting his sight back. So he teaches. His students go out and use what he taught them. They put down every force that stands against them and take rule over the tribes. Adrian works out only after that what he has raised, which is a set of demon gods with the weight to turn the three realms over.
