In the cataclysmic era when Blue Star and the world of Shan Hai Jing merged, the rampage of alien beasts and the revival of spiritual energy completely changed human civilization. In order to resist the invasion of monsters, some humans awaken the "beast soul" by stimulating the potential of their bloodline - a system of extraordinary abilities that resonates with ancient beasts. Beast soul users are divided into F to SSS levels according to their talents, their strength levels range from Bronze to Supreme Nine Stars, and their cultivation rules cover six levels from Yellow Level to Creation Level.
