This is about Su Muyu and Su Changhe of the Dark River when they first started taking on missions.
The Dark River's two great prodigies: one wild, one quiet; one kills, one protects. They have always gone their separate ways.
No one dares approach this walking Asura.
Back then, Su Changhe scoffed. Assassins never needed a weakness, much less backup.
Side by side in their youth, a parasol shielding the Asura, traveling a thousand miles through the night, bound together in life and death.
