Chen Bei's world was completely turned upside down the night he rescued the dog. He can see the "truth" hidden under the neon city: demons.
A sudden "Ten Thousand Demons Book" made him the last "demon master" in the world. But it has also become a thorn in the side of the mysterious organization "Eternal Life Pavilion" - they hunt demon clans and extract demon elements in order to seek immortality.
Forced, he established the "Beiming Ecological Conservation Center" to take in those monsters who had nowhere to go. Little did he know that he had been quietly involved in a huge whirlpool concerning the survival of two races.
When the spiritual energy is completely revived, the ancient demon opens his eyes, and fatal crises follow one after another... Will he become a hunter or a prey? Should we choose coexistence or destruction?
