On the eve of her tribulation, Su Wange, the Qingyun Sect's most gifted disciple, is branded a "calamity star of a thousand years" by the Heavenly Secrets Pavilion. As nine layers of heavenly thunder crash down, the sect's Profound Ice Formation mysteriously collapses. Not only does she fail her tribulation, she also watches the sect leader slash away her senior brother Lu Chenzhou's outstretched hand. With her dantian destroyed and her Nascent Soul shattered, she falls into the Netherworld Abyss. There, the mysterious Netherworld Venerable uses Netherworld Ghostfire to reshape her spiritual roots. From then on, she joins the Netherworld Hall and begins ten years of cultivation in secret.
Ten years later, Su Wange returns to the Qingyun Sect at the Deity Transformation stage. By chance, she reunites with her senior brother Lu Chenzhou, who has been reduced to a menial servant yet never stopped searching for her. As she uncovers the truth about the sect leader's forged prophecy and deliberate attempt to kill her, an even greater conspiracy comes to light: the sect leader is the traitor who framed the Netherworld Venerable and drove him into demonic corruption a century ago, and now seeks to control the cultivation world with the Soul-Devouring Banner. At the critical moment, Su Wange awakens her ancient Netherworld bloodline and burns away evil with Netherworld Sacred Flame. She clears her name and uncovers a century-old feud spanning both factions.
In the end, Su Wange rebuilds the Qingyun Sect and abolishes its harsh rules, while also taking on the responsibility of overseeing the Netherworld Hall and bringing the righteous and demonic factions together in peace. On her path to cultivation, reborn after overcoming tribulation, she breaks the shackles of the Heavenly Dao with her unyielding will and writes a legendary tale of immortal cultivation that transcends life and death and reshapes fate.
