The Heart Demon Carries the Loser Female Lead Through the Cultivation World

Lin Yan wakes up one day to find herself transmigrated into a cultivation torture novel, becoming the weakest heart demon inside the destined female lead's body, one that could be purified and erased at any moment. The original female lead, Su Qingyuan, possesses a ninth-grade celestial spiritual root and is a darling of the immortal path, yet she is timid and soft-hearted, exploited by a hypocritical senior sister, betrayed by her master, and oppressed by her sect, ultimately leading to her dao heart shattering and her soul extinguishing. Watching the fragile female lead about to be toyed with to death, Lin Yan is done. If she stays passive any longer, they'll both die. From then on, the world gains an invincible heart demon hidden within a person's mind. When she cowers and retreats? Lin Yan acts with cold ruthlessness in her place. When her spiritual power is weak? Lin Yan helps her break through barriers and realms. When others scheme with hypocrisy and harm her step by step? I am the heart demon, neither good nor evil, proving the dao through slaughter, protecting my host through killing! The world says Su Qingyuan has changed drastically and fallen into the demonic path. Su Qingyuan's eyes are cold and clear, and in her sea of consciousness, a male voice overlooking all beings speaks calmly: "No matter. If the righteous path won't accept you, I'll lead you to trample it down. If heaven and earth won't accept you, I'll lead you to slaughter through the nine heavens." One heart demon, sharing life and fate, from an insignificant outer sect disciple, defying and slaying prodigies, staining the immortal path with blood, until both ascend to the pinnacle of the world! — Description from novelcodex.org
