I Rely on My Second Personality to Slay Every Demon

[Dark Age, Two Souls Awaken] In an apocalypse overrun by monsters, human civilization has collapsed, and only twenty walled cities remain, struggling to survive beneath a blood-red sky. The gentle scholar Ye Chenfeng and his younger sister, Ye Tingyun, eke out a living in a lawless stronghold where the strong prey on the weak, until a sudden disaster shatters their fragile peace. To protect the only family he has left, Ye Chenfeng takes the brunt of the disaster. On the brink of death, he awakens an ancient personality sleeping within him. When blood stains his vision and he opens his eyes again, the scholar's gentle gaze has frozen into millennia-old ice. His second personality has fully awakened. From then on, a mild-mannered scholar and a cold-blooded god of slaughter share one body. His white robes stained with blood and his ink-dark blade slaying monsters, he wipes out every evil spirit that threatens his sister beneath the suddenly appeared black longsword. From the edge of the city walls to fallen forbidden zones, Ye Chenfeng advances over the corpses of monsters, gradually uncovering the astonishing truth behind this dark age. [Two souls in one body, an ink-black blade to slay evil. For family, for all living beings, he will carve a path through blood!]
