Just another cliché dungeon story

This is just a testI'm not sure if I will continue writing this. I'm not an English native so please bear with it, I'm still learning... If you can give me some pdf containing Basics, rules and etc that will help a lot. Thanks~ for the synopsis here it is.

Synopsis: This story is not an ordinary story it is a very cliché story of a dungeon that wants to be a demon lord. Watch how he buldoze all those who block him on his way to become the greatest demon lord?
