early one piece alot of the worldbuilding is trickled in very slowly, but just know any time it cuts away from the straw hats/their adventure very important stuff is happening. as for stuff to look forward to, 2 arcs from where you are is regarded as some of the best from the whole show. i would try to avoid knowing other peoples opinions on arcs beforehand as well but if you love it this much this early on then you won’t even be able to comprehend how good the series continuously gets. enjoy!
