Lu Yang, an ordinary migrant worker on Earth, unexpectedly died in an engineering accident and transmigrated into the body of a young boy also named Lu Yang. This boy was the eldest son of a common family in Qingyang Town. His father had gone missing five years ago during a beast tide, and now he lived with his mother and five-year-old brother.

Lu Yang quickly adapted to his new identity and discovered that he possessed a magical "Beast Taming System." As long as he met the system's requirements, he could infinitely tame beasts and even upgrade the bloodlines of his battle pets.
