When a modern young man transmigrates into Nezha from Ne Zha: Birth of the Demon Child, who has endured the heavenly tribulation, he discovers that he has become entangled in a shocking conspiracy that could overturn the Three Realms. Shen Xiaobao, younger brother of Shen Gongbao, and his father Shen Zhengdao are a father and son who adopted a half-demon and stand firm for justice. They are hunted down for opposing Yuanshi Tianzun's plan to slaughter the gods. Forced to ally with his old nemesis Ao Bing, Nezha uncovers the truth behind the Investiture of the Gods calamity amid the struggle between the Chan and Jie sects: the fates of the Spirit Pearl and the Demon Pill are nothing but a deception on Heaven's chessboard, while the half of Nuwa's heart she cut away when mending the sky has long since become the chaotic source tearing the Three Realms apart.
In this deadly game spanning time and space, the Red Armillary Sash coils around the dragon clan's reverse scale, while the Map of Mountains and Rivers conceals the blood and tears of three hundred orphans from the Ciyou Orphanage. When Nezha raises the God-Slaying Spear with a Demon Pill body, and Ao Bing's icy dragon breath takes on the color of karmic fire, an ancient secret erased from history rises from the deep: what people call heavenly destiny is nothing but a lie born of the gods' selfish desires. And the love that has entangled them through three lifetimes is the final glimmer of light capable of piercing the darkness.
“If Heaven's will demands that you and I kill each other, then I'll tear Heaven's will apart!”
With their vows sworn upon reverse scales and their pact sealed in karmic fire, watch the Demon Pill and the Dragon Lord slay saints and gods, and write a Book of White Hair for all living beings at the end of the Return to Ruins.
