A cross-temporal mystery and tragic romance built around “three lifetimes of reincarnation,” with “BE blind boxes” as its storytelling hook and reader participation in rewriting fate at its heart. Blending power struggles in the late Ming dynasty, espionage in the Republican era, and near-future science fiction, it follows a clean timeline with one era per volume and tightly controlled flashbacks. Under the control of fate, a man and a woman go from saving one another to defying destiny, ultimately drawing the readers into the script as villains in the fourth life.
