Primordial: I'm the Azure Ox, Supreme Senior Brother of the Three Sects

What happens when you reincarnate as the divine beast serving at the side of the Primordial's mightiest sage? Niu Ben awakens as the Azure Ox—humble mount by day, but destined to become Patriarch Azure Ox, the demon who will shake the heavens. Armed with a god-tier choice system and sheltered under Taishang Laojun's protection, he rises from 'little ox' to the supreme power that suppresses entire eras. In a world of immortals, treasures, and ancient sects, one beast will rewrite destiny itself.
