The top-secret information of the Japanese army was stolen, and the special high school searched the whole city, killing anyone with suspicious personality. Qing Xu, a frail scholar, was serving tea and paper with a low eyebrow, but was kicked to the ground by an officer. No one knows that he is the ace agent "Thousand Faces" who keeps the top brass of the Japanese army awake at night. With a flash of sharpness behind his glasses, he can reproduce any human voice and gait in three seconds; with a slight movement of his fingertips, an inconspicuous pen can shoot through the throat. When suspicious eyes are fixed on this office, the fun has just begun - he will send out the intelligence in front of all enemies, and also let the Japanese army kill each other. Don't forget, the most deadly weapons are often hidden under the most harmless skins.
