Giving Disciples Will Give You Back Ten Thousand Times: My Disciples Are All Villains

Lin Mu traveled to a fantasy world and became the founder of the devil's path between heaven and earth. He was bound to the discipleship system and returned ten thousand times. Whatever is given to the apprentice, the system will return it, and it will be returned after increasing it by a certain multiple. "Ding! You give your disciple a third-grade mortal elixir, and you will get a seventh-grade elixir in return for ten thousand times the critical hit!" "Ding! You give your apprentice an earth-level mid-level skill, and you will get a heaven-level low-level skill in return for a thousand times the critical hit!" "Ding! You transfer 500 years of cultivation to your apprentice, and you will get 50,000 years of cultivation in return with a hundred times the critical hit!" ....... Many years later. "Even if the Heavenly Demon Ancestor is so strong, why are all his disciples top-notch among the monks of his generation?" "Good cannot defeat evil! Good cannot defeat evil!" "Because my master never hides his secrets!" The disciples who have become villains said proudly.
