Fantasy: My Apprentices Are All Destined Protagonists

Su Yun traveled through the fantasy world and got the system that you are worthy of being the protagonist. As long as his apprentice does not become the protagonist of destiny, Su Yun will receive generous rewards from the system. Su Yun naturally agreed to such a good thing. The question is, why did the accident happen? That good-for-nothing who was expelled from the Xiao family and shouted "Don't bully young girls into poverty", how could I kill the Xiao family with just one finger after being fed a few mouthfuls of chicken by me? How come that loser whose supreme bones were dug out suddenly grew new bones after I treated him with *medicine? Why did that mortal who came from a mountain village turn into the famous Old Demon Han with my watering can? … To the end. Su Yun looked at the group of people who came to be apprentices, and couldn't help but roared: "Go away, labor and management only want trash!" The eldest son of the True Immortal Family, the crown prince of the Supreme Immortal Dynasty, and the true disciple of the Immortal Immortal Palace all rushed forward to hug their thighs: "Master, I am a waste!"
