The entire Su family was brutally massacred, and the orphan Su Wan identified the warlord Lu Chenyuan as the killer. She lurked by marrying him for three years, waiting for a chance to take revenge. At the moment of the assassination, Lu Chenyuan confessed the truth: he was a body double for the former warlord, and the real killer who bloodbathed the Su family had long been eliminated by him. Upon learning the truth, Su Wan was filled with guilt, but her surviving sister Su Jingyue, hidden in the mansion, insisted on forcing Su Wan to take revenge, repeatedly poisoning and assassinating Lu Chenyuan. Until Lu Chenyuan produced confidential archives to clarify all past events, Su Jingyue suddenly saw the light, let go of her hatred, and entrusted Su Wan to him. The two finally broke free from the sea of blood and grievances, living in peace and stability together.
