I Am a Demon in the World

I traveled through time and became the last demon king, and the system allowed me to revive the demon religion. But in this world dominated by immortals, demon cultivators will die immediately when they show up. As a person who has completely lost his cultivation, how can I revive myself? Until I accepted the first cultist and unlocked the [Demon Cult Holy Fire] It can repair Taoist injuries and temper the supreme demonic body. What's even more terrifying is that the number of followers directly determines its strength and the growth rate of my cultivation! Looking at this glorious world of immortality, I realized. Isn't the so-called revival of the Demonic Cult just... Turning everyone into one of our own? From today on, all living beings in this world will enter my demonic path.
