Chen Bo's father, Chen She, was once the world's strongest beast-taming genius, and his mother was the Holy Maiden of the Beast God Temple. When Chen Bo was born, the Beast God Orb chose him as its master. During the beast-summoning ceremony, Zhao Lingjun used a beast-contract plundering ability to steal his innate, max-level beast power. Chen Bo could summon only an F-rank pink toad, becoming a laughingstock and being relegated to the beast-taming district to clean up after the animals. In his despair, the toad awakened the god-tier talent Infinite Devouring, allowing it to devour all things and evolve. During the rookie trials, Chen Bo fights back against those hunting him and evolves his toad into the Crimson Gold Demon Toad, Purple Gold Demon Toad, Black Gold Demon Toad, and Gilded Gold Demon Toad. He defeats Zhao Lingjun and kills his SSS-rank Howling Wind White Tiger, leaving Zhao Lingjun crippled. His goal is to rescue his imprisoned mother, take control of the Beast Alliance, and destroy the Zhao family.
