Shen Qingli was reborn after a tragic death, swearing never to join the Jadeite Sect again. In her previous life, her birth mother Zhao Yue, the Saintess of the Jadeite Sect, brutally extracted her Phoenix Bone while she was still alive at the age of fifteen. Shen Qingli had cultivated the Phoenix Bone through nine Nirvana rebirths in a lava cave, a perfect bone forged by her own desperate struggle. Zhao Yue took the bone to save her junior sister Su Chacha, who suffered a cultivation deviation. The sect master and elders all condemned Shen Qingli for lacking camaraderie, and her most trusted junior brother Gu Cihe and the senior brother Pei Yanshu, whom she had a crush on, accused her of abuse. In her past life, after the extraction, she was thrown into the Heavenly Thunder Pool, her foundation destroyed, and she fell into demonic ways only to be killed by Zhao Yue and the sect. Now reborn, she wakes up lying in bed after the extraction, the pain still fresh. Despite her Phoenix Bone gone, she still possesses her Phoenix Soul. Su Chacha and Gu Cihe come to her room to provoke her, with Su Chacha feigning guilt and Gu Cihe mocking her for not willingly giving up the bone. Pei Yanshu also arrives, coldly stating that she is unworthy of being the head senior sister. Shen Qingli endures the pain and stands up with her Phoenix Soul, naming the disciples who had received her help but now turn against her. Gu Cihe kicks her knees, causing her to kneel, and the uncontrolled Profound Energy ruptures her meridians and skin. In desperation, Shen Qingli activates her Phoenix Soul and self-destructs it, shattering the Phoenix Bone inside Su Chacha's body as well. Zhao Yue descends to stop her but fails; the Phoenix Bone is broken. Shen Qingli collapses, and Zhao Yue takes Su Chacha away without a glance. Pei Yanshu expresses disappointment and leaves. Shen Qingli crawls back to her room, dying. But she has a secret: in her previous life, she obtained an inheritance called the Immortal Demon Transformation, a cultivation method that fuses immortal and demonic energies. She still has both pure immortal cultivation power and demonic energy. She begins to cultivate, and the immortal-demon power stabilizes her life force, rapidly healing her body. As she advances, she is drawn into a purple mist world where she obtains the Demonic Doctor Space and the medical inheritance of the Great Power who created the Immortal Demon Transformation. Within the space, she finds Primordial Chaos Qi that can reshape root bones. Shen Qingli wholeheartedly accepts the inheritance, resonating with the core principle that only by being merciless can one achieve the highest. She fuses completely, and her cultivation climbs back up. The purple energy gradually reshapes new, purple-glowing bones where her original bones were extracted. She loses track of time in the space, realizing later that three months in the space equal only three days in the outside world. Shen Qingli emerges from the Demonic Doctor Space, having reshaped her bones and reestablished her cultivation foundation. She is now determined to never have any connection with the Jadeite Sect again. She will pursue power through this merciless path, whether immortal or demonic, and seek her own revenge and destiny, no longer bound by sentimentality or the expectations of others.
