One Piece: My Strength Comes Entirely from Watching the Fun!

This is a bit toxic; it makes no sense at all. You need to store your brain elsewhere before watching it.

The title could be changed or crowdfunded. The current title is too discouraging; the idea that strength can only be improved by watching others perform is already a major flaw. The protagonist could train himself and use a system to improve, a two-pronged approach. The title could be changed to "One Piece: Watching the Show Makes Him the Strongest in the World" or "One Piece: The Justice of Gossip."

The protagonist's name is so cool! Xia Zheteng ☞ Just messing around 😂

The answer has already been given to you. You can't even copy the answer properly? The current version's answer is Physique + Conqueror's Haki + Mythical Beast Species. What's the point of adding those fancy stat points?

No, I've read ten chapters. It's fine if the protagonist suppresses his strength, but please, don't make him a babysitter. To put it bluntly, Ace wasn't worth saving. You start by saying you want to be a babysitter, which is really unwatchable. Suppressing your strength is one thing, but being a babysitter is just unbearable.

Let's talk about the Tremor-Tremor Fruit. It's a complete disaster. The plot involving multiple Devil Fruits plus the Twister-Twister Fruit is also slightly toxic. Devil Fruits are now essentially like divine attributes; you can exploit the conflict between them to make the main Devil Fruit stronger while the secondary Devil Fruit is much weaker.

It's extremely toxic; the male lead is a complete coward with incredibly weak abilities, yet he still acts arrogantly in front of Sakazuki. Why should anyone listen to him? And then there's the pimping and escorting of women.

The earlier parts were all good, but the Devil Fruit abilities are just too toxic. If you're going to write about Devil Fruit abilities, you have to respect the original settings. First, the fruit must be unique. You gave us a power-up with the Tremor-Tremor Fruit, do you think everyone's stupid? Whitebeard isn't even dead yet. And if you're going to eat a fruit, just eat it.

The Seven Warlords of the Sea only came into existence after the Four Emperors, so why is it being written that they want to recruit Shanks as one of the Seven Warlords?

The protagonist's name alone wouldn't make anyone want to watch it.
