End**

It's great, the author's writing is delicate and the concept is exquisite! After searching for many years, I finally found a doomsday novel without formulas! It's a bit slow in the beginning, but it can be seen that it has paved the way for a magnificent apocalyptic world background, a clear main line, the protagonist's refreshing character, various reasonable and creative settings, and a full sense of expectation! The author must insist on writing, at least one million words!
