Returned Glory of the Sect

A fallen sect master unlocks a system that rewards him thousands of times over for training disciples. He deliberately takes in the weakest, most miserable students he can find—only to discover they are hidden geniuses carrying blood-deep grudges. Every pill, weapon, and secret technique he gives them returns to him in absurdly powerful form. With his disciples rising fast and his sect rebuilt in luxury, this broke master is about to become the most terrifying teacher in the cultivation world.
