The protagonist starts off as an "abandoned son". He did not gain the trust of the organization, but was stigmatized as a traitor and hunted by the organization. His only reliance is the unbroken private intelligence line he established during his time as the "Blue Bird", and a heart burned by hatred and faith at the same time. He used the identity of his dead comrade as a cover to sneak into the "Pseudo-Chinese Youth National Salvation Corps" controlled by the Japanese and puppets. Starting from the bottom, he sold false information to the Japanese army in exchange for promotion. He exchanged his "crimes" for the trust of his enemies, and then used his enemies' trust in him to protect more important people.
