In 1938, Shanghai was a giant meat grinder, with military commanders, No. 76, The Super High School, and the underground party fighting secretly. Lin Jianlu traveled through hell, and his identity was exposed as soon as he opened his eyes. The military commander regarded him as a traitor, and No. 76 Wanted to squeeze out the last value of his use. The micro bomb in his body only had 72 hours left. The only way to survive was actually hidden in a ghost file designed by him in his previous life. With the secret combat system turned on, he can capture the micro-expression flaws of his opponent for 0.1 Seconds, can dismantle all code puzzles, and can even rehearse twelve assassination routes in his mind. When everyone thought he was just an abandoned son, he had already walked a tightrope path between the three forces: intercepting the Sakura Operation plan, making a backhand move to make the Special High School and No. 76 Fight each other, and then using false information to fish out the secret telegram of Wang Puppet's highest level collusion with the enemy. The most cruel thing is that he steals information in front of the enemy, and the other party has to pat him on the shoulder and say "Thank you, brother" - this is the thrill of a top secret battle.
