Kunlun's Mystic Venerable Lan Xi botches her tribulation, crashes through a burning building, and falls into the depths of elite mercenary Noy's eyes.
Everyone knows Noy as a ruthless, decisive commander with a cold face, fastidious habits, and iron self-control.
No one knows that beneath his skin, he keeps a bloodthirsty, obsessive, violently insane dark personality locked away.
Two personalities, split between black and white, tearing at each other day and night: this is the deadly tribulation he has spent half his life trying to escape.
Only the metaphysical master who fell from the sky sees through the secret he's hidden for half his life at a glance.
"By day, you're restrained and patient. By night, you're beautiful madness to the bone."
She grips the two fatal knots in his fate, one red and one black, and laughs with wild abandon. "Both of you are mine. I'll keep you in line."
From then on, both faces of this madman bend to her.
By day, he's her cool, celibate, quietly protective source of support. He may be stubborn, but his heart is soft, and all his restraint turns to tenderness for her.
By night, he's a possessive, obsessive beast who clings to her, claiming her as his own. His madness and tenderness are for her alone.
Cursed by dark temple rites, entangled in sinister forces, he is relentlessly pursued by the deadly tribulation of fate.
Everyone fears his twin souls will run wild and turn him into a bloodthirsty demon.
Only Lan Xi wields talismans as a shield and uses herself as a seal, braving dangerous places to defy fate and change his destiny.
She mends his shattered soul and tames both of his mad sides, turning the rest of his life, as deep as an abyss, into years of endless daylight.
