This article was written two years ago. It is my first science fiction novel. The idea was conceived in various domestic and foreign fantasy movies. The main inspiration comes from the famous "brain in a vat" theory. Maybe we are all living in other people's dreams, maybe we are living on a small candy, maybe we are all dead, and only the brain is left running, and we live in our own imagination. You don't exist, and neither do I. The imagination is wide open, the intertwining of virtuality and reality, the joke between fate and us. Highly recommend the film "The Man Without a Surname". In the parallel world, we live different lives because of different choices. Each time I was teased by a different fate, and each time was not perfect. Inexplicably, I like this line in the movie, "When we turn back time in 2092, the old people in their twilight years have just begun their lives, and the babies born in their twilight years are already in their twilight years. I'm just afraid that my life is not exciting enough."
