The end is approaching, and the world is in a state of devastation. The wealthy people have followed the army code-named "Bailuhua" to the newly discovered ninth planet suitable for human survival. There are only some normal poor people left on the earth, as well as various animals, plants and humans that have mutated long ago. In this deserted environment, there is a hotel that opens its doors to everyone. Accommodation and board are provided, with only a small amount of food charged as room fee.
Mission: Unity, care for the environment
