Cloud Curtain Song

At the end of the sea of ​​clouds is a world that people have never imagined. There are floating islands in the sky, and spaceships shuttle back and forth. The giant dragon soaring in the sky is coiled on the top of the mountain. Under the clouds is an endless abyss, and above the clouds are dazzling stars. Traveler in the city above the clouds, can you find your way home?
