In her previous life, Shen Qingyi was the most flawless Bai Yueguang in the Three Realms, but she was sent to the altar by her loved ones and became the emotional nourishment of the ancient god Emperor Yan. After returning from rebirth, she is still delicate on the face, but secretly holds the "Scroll of Nirvana Cause and Effect" in her hand. She played with the red thread of cause and effect with a smile, causing her hypocritical master, brother and fiancé to lose everything one after another, making life worse than death. When the aloof and ruthless god was backlashed by lust, covered in blood and fell into the dust, he humbly begged her for mercy. Shen Qingyi only used the tip of the sword to lift his chin and tied the red thread around his heart: "I won't kill you. I want you to carry this heart with you and continue to ache for me forever."
