Everyone Wants to Survive, I Awaken the Prehistoric Beast Taming System!

[Protagonist fighting beasts + system + no heroine + invincibility ] When billions of people around the world were simultaneously pulled into the prehistoric world, human civilization returned to zero overnight, ushering in not a new era but the Jurassic Period for all. There is no technology, no weapons, just primitive jungles, deadly swamps, and prehistoric beasts roaring through them. Tyrannosaurus rex shreds the jungle, pterosaurs fly across the sky, and mosasaurs lurk in the deep sea. Even seemingly docile herbivorous dinosaurs may become deadly weapons in the next second. The protagonist falls into this wild land with countless ordinary people. From the initial panic to survive, he learns to identify dinosaurs, make traps, build camps, and form alliances. Some people become dinosaur rations, while others become others' prey. The protagonist awakens his survival instinct on the verge of life and death, unearths lost prehistoric relics, tames powerful dinosaurs, and establishes a human stronghold.
