In 2149, the Star Skeleton Clan flattened the earth with one cannon.
There are only 100,000 people left out of 7 billion, and civilization is on the verge of extinction.
The last hope is to dismantle the enemy's crashed space-time core and transport yourself to the ancient times of the earth - to escape pursuit and start over from the beginning in the prehistoric era when dinosaurs were not extinct and alien beasts were rampant.
Teammates are separated, supplies are lost, and communicators are damaged. There are no modern weapons or industrial bases in this era, only——
The wind-god pterosaurs that covered the sky and the sun, the thunder dragons that flattened the woods, and the violent dinosaurs that emitted weird energy rays from their bodies.
To make matters worse, he soon discovers: this world has a master.
The aborigines known as the "Lingxi Tribe" possess space-time technology that far exceeds that of humans. Some of them wanted to kill all the outsiders, some watched indifferently, and some... Secretly saved his life when the forest was about to be torn apart by strange beasts.
At the same time, a track appeared in the sky that should not exist——
The pursuer has arrived.
He only knows one thing:
You must survive in the mouths of dinosaurs, the hands of natives, and the pursuit of the Star Skeleton Tribe, and then take revenge.
