Shen Wang, a down-and-out animal communicator, unexpectedly awakened eyes that can see the "emotional colors" of all things, and was bound to a mysterious "all-spirit affinity system." After being forced to take over an old street zoo that was on the verge of bankruptcy, he discovered that the animals raised in the zoo were not ordinary animals at all, but descendants of ancient mythical beasts and otherworldly demon spirits whose bloodlines were on the verge of being cut off! So, while running a zoo in the city, rescuing extraordinary creatures hidden in the streets, he hatched eggs, raised cubs, and petted mythical beasts. Unknowingly, his zoo became the key to connecting the two worlds, and the cute "little milk dog" he hatched turned out to be the final beast in mythology that could destroy the world...!
