In 1945, the Battle of Xuefengshan ended and the Japanese surrendered.
Confidential Secretary Liu Wubin found a familiar name when compiling the list of the dead. Before his single-line contact died, he left him a badge that could be unscrewed and hidden, with four numbers engraved on the back: 0503.
From that day on, he became the loneliest person in Shaoyang City.
During the day, he organized files for the commissioner, read files for the military commander, and covered up crimes for the inspection captain. At night, he turned every meeting record, every corruption account, and every defense blueprint into a knife thrust into the enemy's heart.
Archives are power.
Four years later, when he used countless files and a badge to complete his rebellion against the entire city - the red flag entered the city.
He didn't run. He stayed.
A spy novel that doesn't talk about love, but only talks about "fatal trust". Two badges, one city, to live for those who cannot get out of the darkness.
