[Space + System + Doomsday Stockpiling + Transmigration Across Derivative Worlds]
An ordinary person, guided by a space and a System, transmigrates between different worlds and lives as freely as they please. They experience all kinds of things and, whenever the mood strikes, can help others too. Everything is up to them! A feel-good power fantasy!
[1] This world is about doomsday disasters! (The transmigration starts later.)
The story is fairly detailed, so it may get a little wordy at times!
Some worlds have couples, others don’t. It depends on the situation!
