In the Forbidden City, which has a long history and profound cultural heritage, there live many cute cats. From the perspective of humans, they live an enviable and leisurely life. Among them, six royal cats are special. They are responsible for protecting the memory of cultural relics of "Wuhua." They entered the world of Wuhua and defeated the destroyer Black Owl time and time again, bringing the world of Wuhua back on the right track and thus protecting the cultural relics.
