After Wearing the Book, My Apprentice and I Took Off Each Other's Vests

Traveling through books + system + rebirth + two male protagonists + cultivating immortals + villain + cannon fodder + master and apprentice + the end of the year, the ending is likely to be OE or HE Text text: Jiang Hanqiu traveled through time to a world of immortal cultivation and became Jiang Xuannian, the elder of Tianxuan Sect. In order not to be discovered, he could only take on the identity of the original owner and took on a young apprentice. He was very satisfied with the young apprentice's hard work, reliability and clinginess. I don't know if God thought that his life was too smooth. Four years later, a system calling itself "360" came to the door and said that he had actually passed through the book, and that he had transformed into the protagonist's villain master in the book. The kind that would be pulled out and whipped by the protagonist after death. The good news is that his apprentice is not the protagonist. The bad news is that the apprentice is the protagonist's cannon fodder brother. He bullies the protagonist repeatedly in the early stage and dies without a whole body in the later stage. The worse news is that the system requires him to accept the protagonist as his disciple, otherwise the system and he will be finished. Jiang Hanqiu, who didn't want to die just yet, agreed, and began the life of raising two apprentices. Keep it up, why does he feel that something is not right there? Why can't the protagonist defeat the cannon fodder? Why does the elder Ke Qing from the next peak keep clinging to him? Hey, wait! Why does this little apprentice look more and more familiar? ! ! Yan Heng: Master, you finally remember me!
