A Traveler Who Started as Douluo

(I'm a newbie. Don't scold me. I don't know how to write this. I just try to write it.) I am an immortal. An immortal who has lived for unknown length of time. My name is Tianjue. One day the door appeared in front of me. Black door. I walked in and I passed out. (Fuck, it's so bad. I failed to write the plot. Forget it, let's make it one from all realms. Just go to other worlds to play.)
