Doomsday arrives, the Jurassic and modern spacetimes overlap, and cities are reduced to dinosaur hunting grounds. Office worker Lin Ye is swallowed alive by a Titanoboa, and unexpectedly is reborn as a Tyrannosaurus Rex cub, picked up and taken home by the surviving girl Su Wanwan, who names him "Xiaodai". Awakening the End Tyrannosaurus Rex System, devouring is evolution—merging the resilience of the giant python, the firmness of the carapace, and the might of the electric eel! Watch the cute little dragon devour wildly all the way, infinitely evolving from a C-grade "useless dragon" into the ultimate overlord dominating land, sea, and air!
