Use Stone Tools for Fighting, Sorry, I Am a Cultivator

When tribal warfare in the Stone Age meets the lost civilization of cultivating immortals. A modern office worker travels across the wild continent and becomes the young leader of a tribe. In this land where life and death are determined by stone spears, bones and arrows, he quietly awakens the mysterious ring that comes with the journey. When a powerful enemy presses the enemy and the stone tools are about to break, the first stone spear with aura attached to it that he thrust out will become a thunder that tears apart thousands of years of ignorance. From the ruins of the battlefield to the Divine Pillar of Heaven, the fragments of inheritance scattered across the continent are waiting to be reunited, and buried deep in the wilderness is the mystery of the depletion of spiritual energy in the entire world. This is the story of a man who used the method of cultivating immortals to create a new world in the Stone Age.
