the human body.

　　Then you have to figure out the exact rules of your imaginary worlds.And you have to follow them.If humans are able to breathe underwater in Chapter 1，your character can't drown in a swimming pool in Chapter 3.The issue here is maintaining your reader's trust.That means the reader is willing to pretend along with you.If you start out with an ordinary detective novel and then throw in someone breathing underwater in the 6th chapter，you will pull the readers out of their imagination.The same thing happens if you change the rules halfway.

　　Part of your preparation work for the novel is to map out its worlds in great detail.You should decide the following issues：the history of the world，the geography，what possibilities it offers，how everything works in this new reality，and how all of these factors affect the way your characters think，feel，and react to things.You don't have to tell your readers all the rules in the first chapter.But you have to let readers know enough to understand what's going on.This also allows you to work out logical problems and contradictions before you start writing.

　　When you are writing，remember to make it feel real.You are inviting readers to visit a new world.They will want to be able to see，hear，feel，smell，and even taste what it's like.Whether your novel's about a world without disease or an undiscovered planet，help your readers feel like they're actually there.
