Seeds of Civilization: A Good-for-Nothing Beats a Saber-Toothed Tiger from the Start

(Transmigration + System + Twists + Comedy + Decisive Violence)

The spark of civilization: a good-for-nothing starts out by beating a saber-toothed tiger, and a primitive tribe begs him to become their god.

A good-for-nothing transmigrates into the primitive era, faces life-or-death danger, makes fire by drilling wood (a miracle), gets a golden finger from the System (a reinforced steel spear), slaughters a saber-toothed tiger, and is worshipped as a god by the primitive people.
