My Disciples Keep Becoming Emperors

A peak master of a cultivation sect awakens a system that gives him 10,000x rewards for every disciple he trains. He takes in a useless disciple and gives him junk items — but the system triggers massive returns, making both the disciple and himself grow stronger. He takes on more outcast disciples, defeats a dark sect, saves his sect, and eventually becomes its leader, setting off on a journey across the realms.
