On the Beast Tamer Continent, Shen Yan has been bullied by his clan for eighteen years and is denied even an ordinary contracted beast on his coming-of-age ceremony. Pushed to the brink, he awakens the All-World Divine Cat System and forges a bond with Xingyu, the Sun-Moon Divine Cat. The countless realms are being corrupted by the Outer Gods of Cthulhu, and this continent stands as the last pure land. As the anchor of the world, Shen Yan collects all kinds of divine cats through summons, crushes his enemies in the clan, competes in beast tamer tournaments, and grows stronger to fend off the nameless horrors pouring through rifts in space-time.
