One Piece: King of the World - Chapter 2 - : My Predecessor Was Mentally Deficient?

It all started when the protagonist downloaded a game called “The Fool (Beta Version)”. Since then, his life has changed.

A simple text adventure game with no graphics, no music, only lines of text and countless options, but every option in the game will affect the player’s fate, because on the opposite side of the game is a real unknown world!

Players cannot enter the different world, nor can they see the scene of the different world. They can only experience what the game characters see and hear every step of the way in the different world through the form of text.

With the progress of the game, not only the rewards in the game can be realized in reality, but also various abnormal creatures in the game began to appear in reality.

Until one day, the game will be tested globally.

An era in which all people explore and hunt treasures in different worlds through “text adventures” is quietly unfolding!

I personally fed Loretta, put her to bed, and played with her. And then her reaction was…? “I want Melody to marry me!” Caught off guard by her endless affection, I too ended up entering the duke’s family, “I’ll stick right by Miss Melody’s side.” And there, it seems I’ve met a young lord who’s an even bigger ‘Melody fool’? All I did was be kind to survive, but why am I being loved…?!
