This is a cross-time and space suspenseful sadomasochism novel with "Three Worlds of Reincarnation" as the skeleton, "BE Blind Box" as the gameplay, and "readers' participation in rewriting fate" as the core innovation. It combines the machinations of the late Ming Dynasty, spy dramas of the Republic of China, and light science fiction in the near future. It uses a clean timeline of a single volume and a single era, and strictly controls flashbacks. It tells the story of a man and a woman who, under the control of fate, go from redeeming each other to confronting fate, and finally pulls readers into the script to become a closed-loop story of the fourth generation villain.
