In the previous life, the demon clan was bloodbathed into the sect. In order to save me, my senior brother did not hesitate to die with the demon king. My only concern in this world was gone, so I went with my senior brother.
But when I opened my eyes again, I saw the same scene as in the previous life. I am reborn! Just like in the previous life, my senior brother rescued the twelve-year-old me from the temple and brought me back to the sect. I swear that I will protect my senior brother in this life.
A system called 750 said that my senior brother was the villain in a novel, and the Demon Lord was the male protagonist. My senior brother and the Demon Lord died together in order to save me. Many readers were furious after reading the ending, the male protagonist was so vicious! I even fell in love with my senior brother and I. So let me save it, conquer my senior brother, and turn the novel into a perfect HE.
I:! Then it's great to say that senior brother liked me in his previous life, hehe~
System: Love brain is hopeless
So I started to attack the senior brother and investigate the demon king...
Mission: Tenacious struggle, world peace
