A paleontology enthusiast accidentally traveled through time and became an Allosaurus baby in the Late Cretaceous 85 million years ago, falling into a prehistoric purgatory where the mortality rate of baby dragons exceeds 90%. There are no fantasy plug-ins, no anthropomorphic dialogue, only relying on the ancient biological knowledge in human thinking, and the [Predator Mark] that is slightly strengthened after killing powerful enemies. He must follow the most primitive survival laws.
After breaking out of his shell, he was faced with the test of life and death. He became five brothers with the steady rock, the unruly wind, the tough shield, and the sharp shadow. They were entrusted with life and death with their roars, limbs, and scent marks. From wandering in river valleys hunting lizards, to hunting adult herbivorous dinosaurs; from leapfrogging to kill Deinosuchus, to fighting to the death for the 10-meter-long Allosaurus overlord in the canyon; from hunting down hundreds of horned dragons on the plains, to hunting the giant land beast Alamosaurus, to going to the north to challenge Tyrannosaurus rex, a super-species monster.
There is no world-destroying combat power, only step-by-step tactics; there is no aloof path to hegemony, only the bond of brothers sharing life and death. The five hundred chapters follow the scientific settings of paleontology, restore the most authentic Cretaceous ecology, and record the legendary journey of five Allosaurus from weak cubs to sweeping across the continent of Laramidia - at the cost of blood and bones.
