Fantasy City: Age of Death and Sea of ​​Fire

My name is Gu Yu, I have traveled through time, and I have traveled to the only world composed of the three major migrant workers: Pirates, Naruto, and the God of Death. But why is this world so strange? There are a lot of old fairies who have lived for hundreds of years, and there are also immortals who have lived for thousands of years, flying into the sky and escaping from the earth, and splitting mountains and rivers with their fists. And people here can only use the abilities of their own world. Pirates cannot condense Zanpakutō, Shinigami have no chakra, and ninjas have no Haki. But why can I use three powers? Only then did Gu Yu realize that he was the only one in this world who could use all abilities! "Old man, I have a bold idea!" Gu Yu came to the fantasy version of the world of the Dead Fire Sea, got the exchange system, and became the only person who could control all the power. When Yu Gu opened the eyes of the Nine Magatama, one hand turned into a thunderbolt, and the other hand appeared with a simple Zanpakutō, the world trembled!
