[System Initalized]This is not something you expect to suddenly hear while deep underground in a cave.

Leo was lost underground in a cave and almost lost all hope to get out when suddenly, the world around him changed.

The whole planet was being altered and the cave he was in became a dungeon filled with deadly monsters.

"Huh? I can't level up without a class? I need to finish the tutorial to get one? Alright, start the tutorial!"

[Impossible to enter tutorial from a dungeon.]

[Please leave the dungeon first.]

[Exit will be open after defeating the Boss.]

Lost and alone, how will he get out? What does the appearance of the system entail for him and for the whole world?His only option is to fight, carving out answers and a path for himself in this new reality.
