Fen Chiang's fatal car accident becomes an unexpected second chance when God offers him a unique mission: reincarnate in Eden, a world where dinosaurs, prehistoric mammals, synapsids, and pterosaurs thrive alongside modern humanity. Tasked with preventing ecological collapse caused by human pollution and exploitation, Fen awakens as Sobek, a spinosaurus blessed with a System and vast knowledge. To counter humanity's dominance, Sobek must rally the fractured dinosaur species into a unified army capable of challenging civilization's grip on the planet. Yet building such a force proves devastating—uniting ancient predators and herbivores requires more than strength, and humanity's refusal to yield their supremacy transforms the conflict into a brutal struggle for Eden's soul.
