Rational Upgrade

Before you open this book, please put away your expectations for a single ending. The world here is woven from multiple timelines and stacked memories: the choices of characters not only shape fate, but also drive the self-calculation of the universe. You will see encounters, misses and reflections, which test each other's boundaries like tides, rather than simple cause-and-effect answers. Read on with curiosity and patience—among the fragments and echoes, what you will get is not a final conclusion, but a new and powerful set of questions. ——To every reader who is willing to be scrutinized by the world.
