Karp can be regarded as Luffy's first master. Karp gradually practiced Luffy purposefully from an early age. He left Luffy alone in the mountains, tied a balloon and rose to the sky. Luffy suffered a lot under Karp's training since childhood, which is also the reason why Luffy has a strong and unyielding temper and self-control ability. Karp can be said to have taught Luffy the most important quality.
On a certain level, Da Dan can also be regarded as Luffy's master, because Da Dan taught Luffy various skills and methods of life. Otherwise, it will be a mistake, but it will lead Luffy astray. It also happens that Luffy has lived with Da Dan since childhood.
Mastered all kinds of life skills. This has enabled Luffy to solve various problems so far and find one powerful partner after another, even if Luffy's single-minded brain is still a bit unreliable.
Nagley, this is also the role of original TV design. He can be regarded as Luffy's master. Luffy first contacted the domineering industry and was adopted by nagley. However, nagley played a role in Roger, the navigation king. At that time, when he came to power, he also released his hegemony.
Luffy saw the strength of nagley and learned from nagley. I firmly believe that Luffy followed nagley and felt the domineering skill at that time, but Luffy is not sure. Even junior high school domineering in nagley's classroom teaching was not something Luffy could understand when he was a child.
Renageli's stage is to touch the domineering of junior high school, so Raleigh teaches Luffy the primary domineering. During the two-year tempering period, Raleigh became a better master of Luffy and taught Luffy how to learn to be domineering.
It is this precious training year that makes Luffy meet an opponent who can't win, and has been recalling Raleigh's course content, and then improving his domineering ability and defeating his opponent in one fell swoop. However, Luffy has not learned high-end domineering, and he has not mastered first-class domineering.
Now, it is finally the turn of high-end domineering, that is, first-class domineering. The master with the highest level of domineering in this education is a thin little old man named Leopard Goro, who is a swordsman and knows how to manipulate the domineering style of spreading shock waves.
Lufei saw this incredible professional skill and gradually asked Uncle Bao how to use this high-end domineering. I firmly believe that Luffy has a little more chance to learn this domineering and defeat the four emperors Kaiduo. That's my answer. I hope it helps you.
