In the shadowy depths of a sprawling city, Zang Yan, a lonely orphan with no family and no pets, struggles to survive in the harsh slums. His life changes one fateful day when he finds a mysterious item discarded in the trash. Intrigued, Zang Yan wears the strange item, only for it to transform into a radiant light one night, embedding itself deep within his consciousness and manifesting as an egg—his soul pet. As Zhang Yan learns to harness the power of his soul pet, he discovers that it is a weak, fledgling creature with immense potential. Together, they embark on a journey to grow stronger, facing numerous trials and challenges. Along the way, Zang Yan realizes he is part of an ancient prophecy that foretells a battle against the soul eaters—fearsome creatures that grow stronger with each soul they consume. With each battle and every hard-earned victory, Zang Yan and his soul pet gradually grow in strength and resilience. In a land where danger lurks around every corner and trust is hard to come by, Zang Yan must navigate treacherous alliances and face unimaginable horrors. His quest will challenge his courage, test his resilience, and ultimately shape the fate of humanity.
