The straw hat and his party officially sneaked into the deep sea and came to Mermaid Island. Defeated the "new fisherman pirates" who tried to seize the sovereignty of "Fisherman Island" and Vander Decken IX who was crazy about "White Star". Then Luffy asked Jinbe to join the straw hat gang. Jinbe refused, because he still had unfinished business, and promised Luffy that he would be very happy to join the straw hat gang once it was settled.

Worried about the safety of "Mermaid Island", Neptune of Mermaid Island and Jinbe discussed that they would like to let "Mermaid Island" borrow the reputation of straw hat to safeguard the safety of residents if it is separated from the protection of "Aunt". At this time, the Royal Guard came to report that the men of "Aunt" had come to collect snacks.

Luffy, Sauron and Shan Zhi pursued cribb, who stole the treasure from the palace, to the main island of "Mermaid Island", and successfully defeated cribb to obtain the lost treasure of "Dragon Palace City". In the dim sum factory, they met Bokmus and Baron Tamago, the subordinates of Aunt, and reported to Aunt that they could not take back the dim sum.

"Aunt" was very angry, and the phone bug wanted to sue Porkmoth and Baron Tamago. As a result, Lufei first picked up the phone bug, loudly admitted that he had eaten all the snacks left on Mermaid Island, and offered to exchange the treasure for the right to eat snacks, but "Aunt" refused to accept it.

So "Aunt" turned to Luffy and others and said that she would wait for the straw hat and his party to arrive in the new world. Luffy declared war on "Auntie" and threatened to defeat her in the new world. Mermaid Island was divided into its own territory. After that, the straw hat and his party set out for the "New World".

Leaving Mermaid Island and entering the new world, Punk Hazard is the first island where straw hat pirates landed after entering the new world. The straw hat pirates and the newborn "King of the Seven Seas" Trafalgar Law formed a pirate alliance on this island, plotting to overthrow the Four Emperors.

Under the discussion of Luo and Luffy, in order to draw out the four emperors behind them, it was decided to capture Caesar alive first, Luffy was responsible for capturing Caesar alive, and Luo was responsible for destroying Sade.

Luffy later caught Caesar and fought fiercely with him. The poisonous gas released by Caesar had no effect on Luffy in the battle, but Luffy was beaten at a disadvantage by armed domineering. Then he used the empty world to stun Luffy and the heavy smoker and catch them.

Caesar is going to use Luffy and others as experimental subjects, and use telephone bugs to inform the bosses of the New World to watch their newly developed killing weapons. Caesar used mucus as a weapon and released poison gas to poison everyone. Luffy, Luo and the heavy smoker escaped from the cage together and then started their own battles. After Caesar was defeated by Luffy, Luo used it as a bargaining chip and threatened to withdraw from the position of Qiwuhai.
