Su Bei sat on No-Sword Peak, contentedly watching his female disciple scurry about.That would have completed his first task for his System Quest assigned by “The Highest Ten Thousand Fold Feedback for Discipleship” system!Xia Ruoching looked at Su Bei with a serious face,“Master, this is the spiritual fruit I got from the Sect Leader. He said it'd be helpful for your injuries!”Su Bei gazed at the half-black, half-red fruit in front of him and fell into deep thought.“Are you sure this is what the fruit looks like?”“......”“This is the real deal, Master! That half is definitely not poisoned! Eating this spiritual fruit would be such a wonderful experience, ah!”“?”“......”Years later.Su Bei, while leading one of his many disciples back to Sword Sect, suddenly sneezed and muttered,“That's strange. Why do I keep feeling like a bunch of people are cursing me?”The eldest disciple looked at the new junior sisters with a stunned expression, “What? You want to kill Master too?”......The book is also known as “I Have the Highest Ten Thousand Fold Feedback System for Discipleship.”“I Am a Transmigrator, Not the Su Bei You Know!”“I Really Didn't Steal The Disciples' Talents, Okay!”“Assassinations from the Reincarnated Disciples!”“Assassinating Master”
