Pirates: Ruler of the World

When Link came to the world of One Piece, it was like a shark came to this small pond and ran rampant. Joyboy is just an ordinary person who was not born in my time. No system, no following, no wisdom, overall planning, clever use of people's hearts, and use force to suppress others. Suitable for old bookworms, but not for people who have no brainers. I just saw someone say that the introduction does not mention the protagonist's cheating. The protagonist of this book does not have any cheating in the form you think. How can I introduce the introduction if there is nothing? The protagonist relies on his brain, but this book is a semi-invincible novel. All readers who read the back must agree with this point of view. Because the protagonist's IQ is really high, he does not rely on the so-called system or other plug-in tools, he himself is his own plug-in.
