I Have a Door That Can Travel Through All Realms

I have a door that allows me to freely travel across all realms. This door is only open for me. As long as my thoughts flash, it will appear in front of me and take me where I want to go. It is my magic weapon to escape and my weapon to defeat the enemy. It is so easy for Buddhas, demons, immortals, fairies and ghosts to catch me wherever they want, and I can sneak attack on them at any time. This novel and its characters are purely fictitious.
