On the Central Province Continent, peace is shattered by the Blood Shadow Sect's evil plot. They intend to use an ancient ritual to open the Gate of the Nine Netherworlds and unleash an ancient Demon God, sacrificing the souls of a million cultivators to plunge the entire Central Province into an abyss of darkness.
Lin Yuan bears the bloodline of the Tiger Clan and possesses the powerful ability to control dark purple energy. Once the phantom of three heads and six arms appears behind him, it unleashes enough power to destroy heaven and earth. Xiao Zhan possesses a mysterious star chart that can not only point the way but also conceal the secrets of the primordial celestial orbits, giving it the power to turn the tide of fate. Chu Yi, an elite disciple from the Heavenly Sword Pavilion, has mastered sword formations to perfection. As his sword energy sweeps across the battlefield, enemies can barely get near him.
By a twist of fate, the three join forces to fight the Blood Shadow Sect. In Myriad Immortals City, they withstand the sect's frenzied assault. Neither the Soul-Devouring Demon Hammer's terrifying attacks, the rampage of cultivators controlled by Soul-Devouring Gu within the city, nor the many crises threatening the city's protective formation can make them retreat. Lin Yuan ventures deep underground to destroy the Nine Netherworlds Guiding Array, while Xiao Zhan and Chu Yi hold the city gates. Together, the three thwart the Blood Shadow Sect's plot.
To eradicate the Demon God's remnant soul once and for all and stop the Blood Shadow Sect's next move, they resolutely set out for the Netherworld Abyss. There, they face attacks from the Nine Netherworlds' guardians and vengeful spirits, as well as obstruction from the Blood Shadow Sect's surviving forces. Their showdown with the sect leader on a stone bridge is especially harrowing. He intends to use them as sacrifices to reforge the Starfall Divine Iron and take control of the Nine Netherworlds. At the crucial moment, Lin Yuan manages to obtain the Starfall Divine Iron, only to fall into the sect leader's trap. The divine iron begins to fuse with the Demon God's remnant soul, and the ultimate battle, one that will determine the fate of the Central Province, begins.
