Yu Rusong, codenamed "Fisherman," woke up and became a traitor to the military who was secretly executed in No. 76. The bullet was loaded and the muzzle of the gun was pressed to the back of the head. The entire Jinling Station knew that he was an abandoned son, but no one knew that he had five layers of spy files in his mind, and the list of secret suspects of the Japanese, the Wang Puppet, the Central Government, and the Qing Gang were all engraved in his memory. No one knew that he would personally hand over his death list to the director of the Special High School, and exchange it for four words: the code name "Osprey". What he has to do is not to survive, but to reshuffle this decadent intelligence battlefield according to his rules.
