After being betrayed by someone he trusted and falling to the lowest point in his life, Xu Yu awakens an unparalleled divine talent for beast taming. He takes in companions with naturally weak innate potential and uses his extraordinary power of evolution to help them break through their limits, one stage at a time, until they become top-tier SSS-ranked divine beasts. Breaking away from the traditional limitations of beast taming, he also builds his own personal army, journeys across countless realms, and subdues all kinds of rampaging demon beasts.
