Immortal Emperor Chen Feng shatters the boundaries of the world with a single thought and descends into the world of Pirate King.
Immortal spirits are nowhere to be found, leaving only crude energy. Fragments of the laws transform into Devil Fruits.
The Marines and Four Emperors are mere ants to him. Even destroying the world is child's play.
He stands with his hands behind his back in Shells Town, his moon-white Daoist robe untouched by dust.
Luffy's rubber body, Zoro's nascent sword intent, the world's conflicts and dreams... In the eyes of the Immortal Emperor, they are no more than a novel evolution of the Dao, a mortal drama worth observing.
Once the Immortal Emperor starts watching the show, the entire world becomes his stage. And he is its sole detached spectator, as well as the one behind the scenes who can rewrite it at any moment...
Don't change the plot. Just travel by yourself. Don't keep following Luffy on his travels.
