Rebirth: I Am The Boss

Reborn as a monster while equipped with the so-called "ultimate pursuit of all game BOSSes" super BOSS gear, Mo Hai discovers that he can transform into any BOSS in the game

The Endless Land, the Sea of Bones, Quantum Space, the City in the Sky, the Illusion of Time and Space, Ancient Ruins, Extraterrestrial Worlds... The legendary places that were once ruled by invincible BOSSes in games will now become his backyard

The game's background in this book is unique, with almost no depiction of reality. The protagonist does not log out of the game, and the book does not conclude until reality is returned.

PS2: This book is a traditional virtual online game, not a time-travel game set in another world. It features a map exploration and adventure storyline, with very few descriptions of dungeons.
