On a snowy night, Lin Yingwan, the oiran of Ningxiang Garden, rescued the dying Suolin Guard killer Ling Yan. Lin Yingwan, who is as bright as a red plum, is actually the daughter of the right prime minister who was framed as a collaborator and her family was exterminated seven years ago. She uses the Immortal Juxing Tower as a cover to secretly run the "Injustice Washing Pavilion" and is determined to take revenge. Ling Ren, as cold as a snow blade, is a killing machine carefully cultivated by Suo Linwei, carrying blood feud and poison. The two began to test and exploit each other. In the shadow of the Juxian Tower and the bloody chaos in the court, their fates were closely entangled. Lin Yingwan used herself as bait, and Ling Ren used intelligence as a blade to jointly trace the truth of the murder in the Prime Minister's Mansion, but step by step they fell into a deeper vortex of conspiracy. When betrayal and sacrifice follow, the cold killer burns himself to protect the red plum, and the proud oiran sacrifices her life in blood. In the end, Ling Ren carried Lin Yingwan's will and truth on his back, and used the endgame as a chess piece to wipe out the blood of his enemies and clear up the injustice. The music of Juxian Tower is revived, and only the new owner in red is left, guarding the cold jade bed and the plum blossom hairpin, in the endless wind and snow, recalling the bloody redemption that burned the heart and eroded the bones.
Purpose: In the abyss of darkness and hatred, two scarred souls approach each other, complete revenge and redemption at the cost of their lives, reveal the truth under the struggle of power, and finally one person bears everything and protects the light on the unfinished road.
