No matter how many reincarnations there are, regardless of gender... Xun Zian travels through different parallel worlds. In different parallel worlds, he has only one purpose... He can live a good life with Yin Zihao, but not all worlds have the happiest endings. Some worlds will not even meet each other, and some worlds have passed each other countless times, familiar and strange, but they dare not recognize each other... And in some worlds, they may be childhood sweethearts and grow old together...
Concept: Among different parallel worlds, there is always a world where you and your loved ones will live how you want.
