Timeline: Parallel Universe

Any groups, individuals, etc. In this work are purely fictitious and are prohibited from being brought in. After reading the dark forest theory, I couldn't help but think, why can't this theory be applied to a parallel world? So this work was born. The subject tells the story of the major crises that their world has experienced from the perspective of three generations of the Wang family, from the time machine to parallel time and space to the parallel time and space alliance. The prologue serves as a supplement to the world view of the official chapters. It means that you can only understand some of the characters' choices after reading the prologue. Of course, there is no problem if you don't read it. After all, the two parts are completely different. That's it, enjoy
