In the ancient wilderness, the world was in chaos, ferocious beasts roared in the mountains and forests, poisonous insects lurked in the grass, and weak tribes could only survive in the cracks. On the verge of death, Shi Yan unexpectedly awakens the inheritance of his ancestors. Armed with the secrets of survival and iron-blooded will, he vows to lead the declining tribe out of despair. When there was no ready-made fertile soil, they used stone axes to split thorns to open up the wilderness; when there were no solid barriers, they used giant trees and rocks to build walls; when there was not enough food, they formed teams to hunt ferocious beasts and tried slash-and-burn farming. He taught the tribesmen to identify herbs, refine tools, set traps, and struggle to survive amidst the cruel laws of nature. Internally, he used his strength to unite people's hearts and break old habits; externally, he used his iron-blooded tactics to intimidate those who wanted to conquer the surrounding small tribes. From a desperate situation with no food to eat, to a tribe full of grain; from a weak person who is bullied by others, to a strong person who can intimidate one party, Shi Yan will embark on a path of rise for the tribe in this wild land, and finally face the conflicts of all races and achieve an immortal legend.
