Most of the protagonists in traditional spy rebirth novels bear "bloody feuds." The protagonist of this book is "potted" at the beginning, but besides revenge, he has an extremely calm personality: he is a "focused calculator." He will not cry or complain, but will regard the entire process of rescuing, lurking, and finding the traitor as a game of Go that is about to be won. The audience will not see the painful struggle, but how the protagonist uses his death certificate to turn the "dead man" identity into an all-conquering disguise card, luring enemies and traitors into the game step by step. This ultimate calmness and cruelty are the most exciting aspects of this idea.
