Hidden Demonic Path

(Non-time travel, no system, traditional fantasy) My grandfather died, in the aftermath of the battle between immortal cultivators. I can't cry. I buried him with trembling hands. … The Immortal Sect said that I am a cultivation genius that is rare to see in a thousand years. … But the Immortal Sect also said, I am a demon, and they want to get rid of me quickly. … In this case, let the three realms see, from mortals to immortals, and then from immortals to demons, to smash this hypocritical world.
