Deep within the bustling city lies Guixu, a mysterious antique shop with no sign or plaque. Only those burdened by strange karmic ties and chosen by fate can knock on its wooden door. The shopkeeper, Lin Wan, is cool and distant, a descendant of the Keepers of the Ruins. She can see the blood, tears, and resentment clinging to objects, and wields the power to judge karma. Through the “Mouth of Guixu,” she purifies guilty souls and fills the abyss known as the Ruins, preserving the balance of the world. She has kept watch alone for a century, seeking to atone for a mistake she made a hundred years ago and recover the soul of the lover who fell because of her. Her own soul is sealed, leaving her unable to reincarnate.
Lu Chen, a special consultant to the major crimes unit and the descendant of a legendary police officer, believes in logic and order. But a strange cold case draws his attention to Guixu. He is coolheaded and meticulous, yet haunted by dreams of a past life and troubled by a deep, soul-level sense of familiarity and attraction to Lin Wan. He finds himself torn between fascination and suspicion.
Lin Wan recognizes at once that Lu Chen is the reincarnation of the lover she has searched for over a century. Their reunion leaves her struggling between longing and resistance. As one artifact from Guixu after another appears and secrets of karma are revealed, the two move from suspicion and opposition to sharing life and death, their souls resonating with each other. Lu Chen’s memories of his past lives gradually awaken, and the bond they shared before merges completely with their feelings in this life.
Lin Wan also discovers that the destruction of her family a hundred years ago, her lover’s tragic death, and her own predicament were all part of a carefully orchestrated plot by a hidden enemy. This enemy seeks to control karma and the power of the Ruins to achieve a sinister goal.
The lovers, reunited across a century, must finally fight side by side and face the hidden enemy and the ultimate secret of the abyss known as the Ruins. Can Lin Wan break free of her seal and redeem herself? Can Lu Chen uphold justice and protect the one he loves? A battle of karmic reincarnation and redemption is about to begin.
