A once-in-a-century top ace agent of the Military Statistics Bureau, codename “Sardine,” is equally skilled in both brains and brawn, with espionage skills second to none. His only weaknesses are his love of gossip, slacking off, joining the fun, and indulging his appetite, all while keeping a laid-back attitude. His guiding principle in the field: if you can coast, never compete; if you can gossip, never work; and if an outrageous trick can solve a crisis, never bother with a serious game of wits. While others risk their lives undercover, he treats it like retirement, becoming a legend in Shanghai’s spy circles with his shamelessly goofy persona.
