Why is Ace always talking to himself?

Wallace is a scorpion fishman born on Fishman Island, located 10,000 meters deep under the sea of ​​the Grand Line, and is the home of fishmen and mermaids.

The island is surrounded by huge bubbles, forming a unique ecosystem. The island's unique architectural style combines the cultural characteristics of fishmen and mermaids, colorful and full of fantasy atmosphere.

The residents of Fishman Island include various types of fishmen and mermaids, who have unique appearances and abilities. Fishmen usually have strong bodies and fish characteristics, while mermaids have beautiful fish tails and human upper bodies.

Fishman Island is also an important trade center, attracting merchants and pirates from all over the world. The market on the island is bustling, selling all kinds of exotic goods and delicacies.

However, Fishman Island also faces threats and challenges from the outside world. Human discrimination and persecution of fishmen and mermaids has always existed, which has led to tensions between Fishman Island and the human world. In addition, Fishman Island is coveted by pirates and other forces, and needs to continuously strengthen its own defenses.

The social structure on the island is complex, with different classes such as kings, nobles, commoners and slaves. The king of Fishman Island is Neptune, a powerful and benevolent leader who is committed to maintaining the peace and prosperity of Fishman Island. Princess Otohime is the queen of the Dragon Palace Kingdom of Fishman Island. She is a brave, kind and visionary woman.

Princess Otohime is committed to changing the hostile relationship between the residents of Fishman Island and humans. She knows that hatred will only bring more pain and conflict, so she strives to promote peace and reconciliation.

She actively communicates with humans and tries to eliminate misunderstandings and prejudices between each other. Her kindness and tolerance have infected many people and made them begin to rethink their views on humans.

Princess Otohime also advocates for the establishment of friendly diplomatic relations between the residents of Fishman Island and humans. She believes that through peaceful coexistence, both sides can achieve better development and a better future.

Wallace is a loyal supporter of Princess Otohime. After witnessing the assassination of Princess Otohime, he was depressed for a long time. Finally, he decided to verify Princess Otohime's view of living in peace with humans. He happened to see Arlong leave that day and secretly followed him to the outside of Fishman Island. However, because of his curiosity, he was attracted by the style of Dressrosa in the Grand Line and got off Arlong's ship.

Wallace is lucky and unfortunate. Fortunately, he met humans who can accept fishmen just after leaving Fishman Island. No one here bullied and deceived the simple Wallace, and he felt respected and cared for. Unfortunately, he was spotted by a group of slave traders in a few years here. Because Wallace was relatively simple, the traffickers took a string of candied haws and abducted him. Fishmen are scarce outside and can be sold for a sum of money. In the end, Wallace was sold to the passing Tianlong man, Peter II (Saint). If nothing unexpected happens, his fate in the second half of his life will be very tragic, but he was lucky enough to encounter a robbery and escape back to the sea. Maybe the curious little fish will have good luck.

After escaping from the Celestial Dragons, Wallace discovered a truth: there is strength in numbers. So he decided to find a partner, so that if he was kidnapped, someone would come to rescue him.

While he was escaping in the sea, he happened to see Ace and others fighting with Steve, and felt that this group of people could be partners. While Lab was not paying attention, he sneaked into Lab's body.

Who knew that after entering, he found that the space inside was really large, and there was even a building that opened a door casually and walked around inside.
