The protagonist of the second season of " Nine Regions Sky City " was not the original. In the first season, the protagonist was a young man named Qu Chuxiao. At the end of the first season, he had already left the Nine Provinces Sky City and headed far away. In the second season, a new protagonist appeared at the beginning of the story. His identity and background were not clearly stated in the first season. Therefore, the protagonist in season two was different from Qu Chuxiao in season one.
