After dying following a car accident, Fen Chiang finds himself in a limbo between the afterlife and the mortal world where he meets God, who makes him a strange request: to immediately reincarnate in a world called Eden, where all species that existed on Earth (dinosaurs, prehistoric mammals, synapsids, pterosaurs, etc.) coexist together, to save it from the human beings who are destroying it due to excessive pollution. Armed with his knowledge and a System, our hero, now reincarnated as a spinosaurus named Sobek, must embark on a difficult journey to reunite the dinosaurs and curb humanity's greed. However, defeating the most powerful species that ever existed will not be an easy task even for a dinosaur army, and surely humanity will not abandon the title of dominant species very easily...

I'm a spinosaurus with a System to raise a dinosaur army

Memory reminded him of the t-rex's footsteps, which made him shiver. However, he quickly understood that it couldn't be the case: a tyrannosaurus wasn't that heavy. Those footsteps seemed to have been produced directly by a mountain that had been magically given legs and had begun to walk. 


Sobek stood up, eager to find out what was causing that sound. However, when sleep completely abandoned his eyes and he was able to focus, he almost jumped back! 


Next to the islet tha he had turned into his home there were a group of real behemoths that were peacefully crossing the swamp. They had huge necks at least nine meters long and just one of their legs was taller than him! 


[Prey identified: Dreadnoughtus schrani, titanosauridae. Experience: 200,000 points] 


Sobek was stuck. For the first time he met the giants of prehistory: the sauropods!
