Adopt the in-depth setting of "double-sided undercover" + "information decoding". The protagonist's "golden finger" is not military force or superpowers, but his photographic memory and extremely unique information decoding ability. He can extract key information that ordinary people cannot detect from public documents and daily conversations. He must not only complete organizational tasks under the supervision of the Japanese and puppets at all levels, but also skillfully use the contradiction between the military commander and the Japanese and puppets to cover himself, and achieve the ultimate performance of "one person plays the role of a triangle".
