In the immortal realm, Immortal Venerable Yun Che was deceived in his early years by junior sister Lin Wanyi, mistaking her for his savior from back then. For three hundred years, he blindly repaid her kindness, constantly exploiting and harming his dao lü Qingyu, who had truly saved him, until at the master's ascension ceremony, he personally extracted Qingyu's immortal bone, causing Qingyu to bleed to death in misery. Qingyu's soul lingered in the mortal world for forty-nine days, witnessing the entire process of Yun Che misplacing his sincere heart and shielding Lin Wanyi, only to fall into endless madness and remorse after the truth came to light.
