Prehistoric: the Beginning of Rebirth of Chaos and Pangu's Obsession

What would you do if you were reborn in an era when Hongmeng had not judged the world yet? What would you do if you became the brother-in-law of Pangu? If you could modify the rules and recreate magic weapons at will, what would you do? What would you do if Nuwa and Houtu were involved? What would you do if this was all a conspiracy?
