Ten Thousandfold Rewards for Taking Disciples, Now I'm Forced to Rule the World

Ye Lan arrives in the Desolate Heaven World and unexpectedly awakens the Disciple-Tutoring Rebate System. He was supposed to laze around and do nothing, but his senior sister unexpectedly takes on a disciple who will one day become a female sword immortal. He has no spirit stones to give his disciple, so the system returns them ten thousandfold: a million spirit stones, just like that. Every one of his disciples is incredibly powerful, yet they all love to brag. First disciple: "Master is mine." Second disciple: "Senior sister, Master and I have already become Dao companions." Third disciple: "Senior sisters, as the junior sister, I've already introduced Master to my parents, and he agreed to marry me." Under pressure, Ye Lan passes on his power to his disciples, and the system returns it ten thousandfold. "You ungrateful disciples, look what you've done!"
