So begins the survival story of a former shut-in with incredible willpower, living as one of the lowest-ranked beasts in a world of magic!ᆖMusic suddenly started playing in my head.I'd been waiting for this moment for so long.'Snakes! Assemble'....

All I know is this is just wrong. I was just reading the latest chapter of One Piece in my computer. And an annoying survey popped up asking me if I want to play One Piece new beginning. Thinking nothing of it I said yes.And selected ‘Realistic’ difficulty.There was a game loading screen. Loading gibberish, and warning me that the world has a lot of surprises in store for me. Not all things are same, because I had to choose the ‘developer’s time-line’.And then telling me to brace for Character Synchronization. And before I knew it, I was no longer your average Joe. And this wasn’t earth either… no this was One Piece.And, I was Monkey D. Luffy. The future King of pirates.I mean what could go wrong? If Luffy could do it, so could I.But this wasn’t the same One piece world I remember. Some changes are small like Kuina being Zoro’s rival… who’s alive.While others were huge. Like… did you know, Whitebeard had an actual beard?! Man looked like Santa Claus on steroids. Jaked and shit!Just what did I get myself into?But does it matter?No.Because I’m going to have the time of my life. This was going to be one heck of an adventure.

In the past, the giants of the heavens and the gods were destroyed after the reincarnation of the world! Cruel curse, eternal hatred, Tan Yun is determined to never sink again! For the sake of loved ones and relatives, from now on, step on the corpse of the enemy step by step to surpass the peak! Defying the sky, killing all worlds, I am the only one!
