There is a subway station hidden in this world. As long as you are sincere, it can allow you to go back to the past, travel through the future, or start over in another time and space with another identity.
It's just that after so many years, very few people can actually go to this subway station. Because there is a rule in this subway station that scares the world, a fatal flaw: you can only go there but never come back.
