Should i write a book based on this?

Well... um... I would improve your writing first. You tell the story instead of showing it. That it the number one thing you need to worry about. Also slow everything down, it goes way too fast and before the reader gets done with one thing they are yanked to another. It's too busy. Also it's a bit random. You have too many things going on and it gets unrealistic which shouldn't happen. Even those fantasy books have to have realistic aspects to it otherwise it doesn't work. You need to balance it. Describe everything more, it's too blank to me, instead of a painting being painted for me there is a blank canvas with scribbles from a pencil on it. It's not vivid enough. This is called constructive criticism and it works wonders. I hope I helped you!
