A craze for virtual games has swept the world, where dinosaurs once ruled the Earth for hundreds of millions of years. This particular game involves traveling back to the dinosaur era, using battle cards to make one’s purchased pet dinosaurs fight against the dinosaurs in the virtual game. Something terrifying eventually happens—a hundred thousand children and youths across the world suddenly vanish. The common trait among them is that they were all deeply fond of this game, including Tianle, who loves fighting games, and his baby dragon, who also disappeared. Based on clues provided by Akun and the baby dragon, An Xiaoda discovers that the mysteriously vanished Yang Tianle has been transported to the Douluo World, and learns that this Douluo World holds the fate of humanity in its hands. An evil force is slowly closing in on both the Douluo World and the human world. With strong determination and intense curiosity, Yang Tianle, An Xiaoda, and Wang Meihan venture into the Douluo World, embarking on a difficult and thrilling adventure.
