On Shampoo Island, Luffy angered Celestial Dragons to attract General Kprusoian, which led to the adowa of the straw hat pirates. Unable to protect his partner and witness the high-level war of the master, Luffy deeply felt the importance of strength. To this end, he did not hesitate to rest for two years, followed Raleigh to learn domineering, and mastered the domineering of the overlord. Two years later, he returned from his studies, and the king of the straw hat pirates returned and officially set sail for the new world. Today's Luffy can make waves in the new world, and Rowley's teaching is indispensable.
Lufei was the first master when he was a child. He was domineering and his strength was unknown. It is said that he fought against Roger the One Piece, but he was defeated and lost with his partner. When Najib first appeared, he stared into the bear's eyes and scared it away. He was worshipped by Luffy and studied under him. However, Najib did not refuse Luffy. He once instructed Luffy to practice and was considered as one of Luffy's first teachers.
Luffy's first master as a child was also Luffy's grandfather Karp. He is also an overbearing master. According to Luffy's memory, Karp trained Luffy and Ace when he was very young, which was a terrible memory. In order to train Luffy's viability, Karp once threw Luffy into the abyss, hung it on a branch, and even tied a balloon in the sky, giving Luffy indomitable spirit and tenacious willpower.
Dada was also a great beauty when he was young, and his beauty was not lost to the female emperor. When Karp was in the capital of seven waters, he once said that he would invite mysterious friends to help him train Luffy. At that time, he thought Luffy had a mysterious master, but later he knew it was Du Dan. Although Dada's fighting capacity is not very strong, it is also the life of Luffy. She brought up Luffy and Ace and taught Luffy many survival skills.
