One Piece did not directly reverse the plot after beating up Brother Ming. Instead, he continued to tell the development of the story. In the following plot, Luffy and the others experienced a series of adventures and battles. Finally, they found the legendary One Piece treasure and fought fiercely with the navy. During this process, Luffy and his companions gradually grew and became stronger. In the end, they successfully protected One Piece's treasure and defeated the navy to realize One Piece's dream.
The One Piece anime isn't fully caught up to the manga. There are still significant story arcs in the manga that haven't been animated. This is common in many long-running anime series.
It's tough to give you an exact chapter number because it keeps going. But you can easily get the latest info by visiting manga subscription services or popular manga discussion groups.
Honestly, it's anyone's guess. The production teams for the anime and manga have their own considerations and timelines. Sometimes, they might deliberately keep a gap to maintain the excitement and longevity of the franchise.
There's no set answer. It all depends on how quickly the manga progresses and how the anime production team decides to adapt the story. Sometimes, they might slow down the anime to avoid catching up too soon.
