The sequel is named because at the end of the story, what happened to Wang Yan and Yan Fen in the vacuum chamber designed by Wesley, whether it was death or life, has never been clearly stated. In the past twenty years, I don't know how many times I have been asked, what happened to these two people? What happened to these two people, there is really no answer, and it has never been mentioned in all subsequent stories, and it has always been a mystery. The idea of ​​the whole story, from the ancient Inca to ancient Egypt, is naturally created out of nothing, but there is a very complete assumption, which is a very happy thing in the process of creation.

The eternal mystery seems too cruel, I hope I can have a chance to solve it.
