Yan Luo is the female protagonist of the novel. She is a three-year-old girl who has been reborn with complete memories of her previous life. In her past life, she possessed the Koi Luck artifact, which drained her life force and fortune until she died of thirst at age sixteen. In this life, she intentionally lets her senior sister Chu Yue take the Koi Luck while she takes the Yin-Yang Eyes, a black jade plate that allows her to see and absorb evil ghosts. She is small and slender with big black eyes, often appearing innocent and obedient. However, she is cunning and resourceful, using her knowledge of future events to avoid past mistakes. She discovers that the Yin-Yang Eyes can be fully activated with a second drop of blood, allowing her to devour ghosts to enhance her cultivation. After arriving at Duke Zhong's manor, she is adopted by the Third Branch, where she befriends the ghosts Ahua and Old Qian and begins to plot against those who wronged her in her past life.
