Though their souls survived the Calamity, Nezha and Ao Bing's physical forms are fading fast. To save them, Master Taiyi intends to forge new bodies from the mystical Seven-Colored Treasure Lotus. Yet, the path to rebirth is perilous, encountering unforeseen obstacles at every turn. Where will their destiny ultimately lead them?

From the primordial essence of the universe, a Chaos Pearl imbued with immense energy is formed. The primordial lord, Yuanshi Tianzun, refines this pearl into two separate entities: the Spirit Pearl and the Demon Orb.

The Spirit Pearl is destined for human incarnation, poised to be invaluable in aiding the righteous King Wu during his campaign against the tyrannical King Zhou. The Demon Orb, conversely, is fated to spawn a Demon King who will bring calamity to the world. To prevent this, Yuanshi Tianzun casts a Heavenly Tribulation Curse – in three years' time, divine lightning will descend to destroy the Demon Orb.

The immortal Taiyi Zhenren is entrusted with the crucial task: ensuring the Spirit Pearl is born into the body of Nezha, the son of General Li Jing of Chentang Pass. However, through a twist of fate and unforeseen circumstances, the Spirit Pearl and the Demon Orb are mistakenly swapped.

Nezha, who was meant to be the world's hero, is instead born as the incarnation of the Demon Orb, becoming a mischievous, rebellious Demon King. Despite his defiant, unruly, and trouble-making nature, Nezha secretly harbors the heart and aspirations of a true hero.

But faced with the fear and prejudice of everyone around him due to his demonic origins, and with the destructive Heavenly Tribulation drawing ever closer, is Nezha truly destined to succumb to his nature and become the demon they all perceive him to be? What path will he ultimately choose?
