A university student has passed through to the prehistoric period; will history still evolve along the original trajectory?

In this ancient wasteland of ruthlessness and bloodshed, Edward armed with his imagination and human knowledge of the 21st century is out there to lead his small tribe into creating an empire for generations to remember.

From introducing fire, the secrets of the soil, and aspirin to launching the savage cave fashion show.

But against him stands his savage rivals, ferocious beasts and hundreds of barbaric ethnic groups.

This is a rewrite of my story after a hiatus. It's done in order to perfect the story. My first work had major grammar mistakes. 

I hope you may enjoy my work.
