I Made Up Cultivation Techniques, and My Disciples All Became Emperors

Pei Yan: I really don’t know any cultivation techniques. I’ll just make one up. First Disciple: Master is truly a sage! This technique is so profound. System: Tenfold rebate! Congratulations, Host. You’ve received an enhanced cultivation technique and ten years of cultivation. Pei Yan: My disciple, that’s not how you practice it. Come, come. I’ve patched a few flaws in the technique for you. Study it again. Years later, Pei Yan discovers that every one of his disciples has become a mighty Great Emperor, renowned throughout history, while he himself has become the sole ruler of the world.
