Four Extremes Lock: The Azure Dragon Awakens

A mysterious train carrying strange ice statues suddenly appears at the border city within the Cold Heaven Secret Realm, accidentally revealing the ancient secrets of the Azure Dragon buried at the bottom of Changbai Mountain's Heavenly Pool for ten thousand years. Xiao Chen, a mountain guardian bearing the ancient bloodline of the Deep Abyss, lives alone deep in the snow mountains, tirelessly suppressing a wild beast on the verge of breaking its seal. When the seal becomes critically unstable, a mysterious black-robed powerhouse suddenly appears, calms the snow mountain disaster with bare hands, and makes a shocking proposal to Xiao Chen. Instead of waiting for the disaster to descend, they should venture into the Heavenly Pool Secret Realm to balance the only remaining ancient Azure Dragon left in the world. A journey through the secret realm that shakes the fate of heaven and earth and concerns the survival of humanity has thus dramatically begun.
