Rebuilding the World from a Crowbar

In the flow of time, I, an ordinary urban youth, was selected by a mysterious system that called itself the "Eye of Creation" and traveled to the distant Stone Age. When I opened my eyes, I was surrounded by the vastness and unknown of the primeval forest. The land under my feet was untamed, and the roars of wild beasts echoed in the distance. In my hand, there is only a seemingly ordinary but extraordinary crowbar - this is the initial tool given to me by the system, and it is also the key to creating a new era in this wild world.
