This is a Cthulhu-style fantasy adventure story. "The oldest and strongest human emotion is fear; and the oldest and strongest fear is the fear of the unknown." On the adventurous journey, what overwhelms "fear" is "longing" and "curiosity" about the unknown.
In the 447th year of the Apocalypse, the "new species" mainly on artificial satellites and the "prototype people" living on the earth started a 19-year "contract" contract. Each side sent 19 teenagers to the mysterious "Hermes" abyss to mine "relics". As a new batch of "visions", the "new species" Ogg and the "original model" Yaheng met at the entrance of the abyss. A magical but depressing adventure begins...

The writing is poor, it focuses on two male protagonists taking risks to level up and fight monsters, and the emotional line is relatively secretive.
