A young man who can see the "backstage of the world" and a father who writes "stories".
Every time the soul travels, it is a thrilling adventure in another world; every time it returns to tell, it is a tacit secret relay between father and son.
When the young man's consciousness gallops on the battlefield of fairies, demons, and ghosts, and when the veteran writer's strokes trace out the skeleton of the magnificent world, an endless "Traveler's Diary" slowly unfolds.
This is not just one person's adventure, but a family's way of protecting each other.
The son uses life as a pen to carve footprints in the endless plane; the father uses love as ink to build a harbor for the lonely soul.
Open this book, and what you will witness is the tempering of the soul, the boundary of fantasy, and the dissatisfaction of a soul who wants to get rid of the time-travel system and just want to be a normal person!
