Lu Jing inherited a pet hospital that was on the verge of bankruptcy, but unexpectedly awakened the ability to understand the voices of mythical beasts, and was bound to the 'Ancestor Furnace of the Bloodline of Divine Beasts'. On the first day, he treated a stray orange cat (Taotie) with indigestion and helped him heal his gastric perforation by smelting his blood. Since then, the nine-tailed fox, phoenix, unicorn and other mountain and sea mythical beasts have turned into pets and come to seek medical treatment.
