Primordial Era: I am the direct descendant of the orthodox Xuanmen sect.

What? I took a nap and ended up in the prehistoric world?

Something's wrong with my hands. Why can't I feel my hands? Where am I?

Oh, so my hand is gone. Why have I turned into a cloud of gas?

Why do these three old men say I am their child?

Wait, aren't you three brothers? Why would you say I'm your child?

This is the story of a time traveler who arrives in the prehistoric world and causes a small change to the prehistoric world that was originally going to be completed.
