[Tough, strong, and insensitive little sun Family blood feud, the immortal family is indifferent, she is determined to break up with her master, but she doesn't know that under the black iron ghost, the mad devil who protects her every night... A big outrageous incident in the three worlds, the new love and the old love are actually the same person? ! [Warning for abuse of the male protagonist] The ancient battle caused the male protagonist to have evil thoughts in his body, and after that, he went crazy online watching the immortal master with two souls in one body! He is both the cold and broken leader of the Yuxiao clan who cuts out his heart and resists calamity; and he is also the fierce and domineering Supreme Being of the Demon Realm who protects her from danger. The fairy soul has exhausted its original source and is on the verge of death; the demon soul suppresses the overwhelming demonic nature and is willing to act as a "substitute" - "I am not him! You see clearly!" When Little Sun wants to accept the crazy demon master, he is shocked to find that the master's spirit of hatred is locked under his skin - let go of the past and love him? But they... Are one person? 2 People? 1.5 People? ! She is messy! The Demon Lord is also crazy: Is she approaching because of him? Or looking at that cold fairy soul through him? ! Until he cut out all his evil thoughts and left only the "perfect" immortal body - the peace of the three realms, she caught a hint of familiar evil in his cold eyes: "What? Are you starting to think about 'myself'?" The "purification" of the Demon Lord is not to disappear, but to be accepted by the subject. It turns out that accepting darkness is his strongest stance! > Core idea: Strength comes from completeness, not from rejecting a part of oneself. [Both male and female protagonists heal and grow]
