You can find the same book by simply typing his name on Google.] [It's a translation of a One Piece fanfic that I like. I've read up to chapter 93 and now I have it on pause. I'm surprised it's not on Webnovel. I'll translate it with ChatGPT. I'll modify a couple of things, like Chinese names, fights costing the MC, the MC's name, etc.]
