This city is bigger than the whole world. The city that was born together with the world is hidden in the corner of the world and cannot be entered or exited. As time passed, this city possessed advanced technology and ancient witchcraft, which gave birth to a new faith that rivaled the city owner's faction. On the one hand, there is the admiration and contempt of people outside the city, and on the other hand, there is the fighting and intrigue among the sects within the city. This city was pushed up into the clouds, but it also enjoyed the rewards of the next life. And forever isolated from the world.
