I Have a Creation Cube

A girl named Qiyue got a mysterious Rubik's Cube. She didn't know where it came from. When she twisted the Rubik's Cube, something magical happened and she entered a completely blank space... Magical monsters can be created in this world, and all knowable and unknowable things can be created. Anything that is logical can be created in this world. If you are dissatisfied with the things of this world, you can destroy them in the blink of an eye. Then, suddenly one day, Qiyue discovered that she could manifest the things in this world into reality... So, she built a system for the Rubik's Cube, and then became a novelist, well, the kind that follows what she says.
