On the way to escape, he also met his college goddess, and so on! Isn't the fat man I saved going to be a five-star general ten years from now? Why did he become his little brother in this life? Can this system also test the loyalty of those around you? How about I open my own apocalyptic base? This novel and its characters are purely fictitious.
