I'm Working on Infrastructure in Dinosaur Park

After waking up from camping, Zhang Heng fell into a parallel world where dinosaurs had ruled the earth for 160 million years. There were no asteroid impacts here. There are only giant beasts that cover the sky and human tribes in the Stone Age. Human beings are no longer the spirit of all things; Just a snack in the teeth of Tyrannosaurus rex, prey as the pterosaur hovers. Winter is coming, heavy snow has closed the mountains, His tribe only had three days of food left, and extinction was imminent. And he only has a bag of salt, A bag of candy, a Swiss Army knife, and a fifty-cent lighter. He lit the fire that the savages regarded as gods! The dinosaurs that the savages were trying to escape from, he bent his bow and arrows and killed them until they fled! Zhang Heng used his own advantages to Use science as the blade and civilization as the fire. Burn pottery, smelt iron, build cities, and train troops! Tame dinosaurs and build city-states, In this wild land, a civilized era belonging to mankind was suddenly created! Human hell is my dinosaur paradise!
