Late at night, the Kwantung Army headquarters was suddenly surrounded by heavy troops, and the top-secret list code-named "Nightingale" was leaked! Three comrades died on the spot to protect Cheng Qian. The traitor laughed maniacally and put the gun to his temple: "Counsel Cheng, if you don't tell me you are online, I will let you watch your own flesh and blood twist with your own eyes!" Cheng Qian suddenly smelled the lingering smell of herbs on the other party's sleeves, and sneered at the corner of his mouth - Doctor? That happens to be his best disguise. Three seconds later, he took advantage of the opportunity of vomiting blood to crush the poison sac in his dentures and went into shock on the spot. When everyone thought he committed suicide out of fear of crime, he opened his eyes in the morgue, knocked out the Japanese guarding the corpse with a knife, put on a white coat and walked to the operating room. Before dawn, he personally dissected the traitor's stomach and took out the wax pill containing the map of the 731 base. But he didn't know that the dying "New Beijing Commissioner" he had just rescued was his first love who had been lost for ten years.
