Yuji was once a weak human, ridiculed for his fragile body and average talent in cultivation. His only solace was his family, but even that was ripped away when a monstrous dragon obliterated his city, leaving him to perish in flames. As his body burned, Yuji made a desperate vow: if given another chance, he would rise to power and take vengeance, no matter the cost. Reborn as a lowly Red Monkey in a world dominated by powerful spirit beasts, Yuji discovers the Origin Beast Reincarnation System, a mysterious force that grants him the power to cultivate, tame beasts, and evolve beyond his wildest imagination. Starting at the bottom of the beast hierarchy, Yuji must fight tooth and claw to grow stronger, subdue his enemies, and carve out his place in a brutal, unforgiving world. With unique abilities, strategic cunning, and an unyielding thirst for revenge, Yuji sets out to become the Beast King—a force feared by beasts and humans alike. But as he rises through the ranks, forging alliances and crushing rivals, Yuji begins to realize that his journey may lead him to a destiny far greater than revenge.
