The fantasy of the Republic of China + the extreme environment of "Eternal Night" + the supernatural element of prediction. The heroine is not a typical bitter and revengeful heroine. She is sober and selfish, and in the harsh environment she has developed the resilience to do anything as long as she lives. The male protagonist is not a villain in the superficial sense, he is a "human weapon" whose humanity has been wiped out by the war. He came to Yongye City to avoid the capital's liquidation, but he cannot change his obsession with killing in his bones. The key words in the relationship between the two are: "savior" = the inversion of "destroying the family's enemy" + the ultimate pull of "while relying on you to survive, while planning to send you to the execution ground". The core point of the story is that the female protagonist knows that the male protagonist is her enemy, but he does not know; the female protagonist must grow up, accumulate strength, and lay a dragnet under his eyes, while also dealing with other unknown threats in the Evernight City where cases are frequent.
