Xue Xi is forced to fall in love at first sight with this dangerous man on their first meeting. With death being the only other option, she makes the first move:

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.

He Lang died by his own hands for the sake of his imperial younger brother’s ambition, whom he loved. He was offered to be reborn in exchange for giving up his past romantic feelings. Reborn without the burden of his romantic feelings, he brings with him a manual to new worlds. He wholeheartedly followed the instructions of the manual to complete the tasks, not knowing that the originally slag gong was blackening…
He pleaded to his affectionate Emperor brother to release him, he pleaded to the paranoid prisoner next door, but until the end he remained baffled.
In the end, he discovered that the full name of the manual was – “Slag Shou Cultivating Manual”
