Traveling through Shanghai in 1939, I became an archivist at the lowest level of the military system. But it doesn't matter, I have my own "Yuanbao" intelligence system - I can tell who is the mole at a glance, and I can restore all deletion records by touching the file. When I dug out the evidence of the webmaster's corruption from the expense reports and pieced together the shocking conspiracy from the old files, those high-ranking big shots didn't know yet: this ant in their eyes was about to overturn the entire chess game with information gaps.
