Chen Xuan awakens in a parallel world where humanity coexists with powerful phantom beasts, ranging from gentle companions to city-destroying monsters. In this realm, Beast Tamers are revered heroes who command these creatures to protect civilization. Transmigrated into the body of a young man living in the isolated Holy Dragon Village, Chen Xuan discovers he has inherited a legendary dojo and a mysterious past.

Just as he grapples with his new reality, an automatic treasure-hunting system activates, guiding him to a buried treasure: a dormant Holy Dragon Egg. Using a sacred family heirloom, Chen Xuan successfully hatches the legendary beast, triggering a burst of holy light that miraculously heals the ailments of every villager. Now bound to a rare Light-attribute dragon with immense healing and purifying powers, Chen Xuan stands on the precipice of a grand journey.

With a powerful partner by his side and a system that hunts treasures, he prepares to rise from a remote village to become a top-tier Beast Tamer, uncovering the secrets of the ancient Holy Dragon lineage along the way.
