After Being Rejected by the Sect, I Established My Own Immortal Sect!

In my previous life, I spent ten years drifting in Beijing, only to fail miserably. Returning home to start a business, I finally achieved success. In this life, after six years of seeking immortality, I was deemed a waste and rejected by the sect, returning home in disgrace. I originally intended to settle down, marry, have children, and live a life of idle wealth. However, I unexpectedly received the inheritance of an immortal and the treasured artifact of the demonic path... I aspire to become an immortal, using the thunderous methods of a demon overlord!
