I Became a Saint by Deceiving My Master and Destroying My Ancestors.

I thought I could only lie down and die as a useless person after traveling through time to become an immortal, but unexpectedly, I awakened the "Rebel System". The system told me that every time I deceive my master and destroy my ancestor, my cultivation level will skyrocket. I backhandedly reported the master for secretly possessing demonic skills, causing him to be deprived of his cultivation. The next day I broke through the golden elixir stage. Master committed suicide in prison and left a letter in blood wishing me the path to immortality. The decent people call me a traitor, but I have become a Nascent Soul and will soon sit on the supreme position of the Immortal Alliance... This novel and its characters are purely fictitious.
