Guang Xiaoyu always believed her senior brother was nothing more than an unremarkable cultivator—until the day his ordinary pet cow obliterated an entire legion of Divine Kings with a single hoof strike. A black dog unleashed devastating Sword Qi from its jaws, holding back millions of Demon Race warriors single-handedly. The prattling Earth Chicken she'd dismissed as mundane revealed itself as a reincarnated Ancient Phoenix bloodline! Her entire understanding of the world shattered! Zi Ji: "Senior sister, disaster strikes! The Demon Emperor commands an army of millions—they march toward us now." Guang Xiaoyu: "Senior brother, I need you!" A tale woven through divine beasts and their hidden legacies, the Demon Emperor's rebirth, the Netherworld's daughter's resurrection, and one cultivator's extraordinary path to mastering the bonds between human and beast.
