Jiangning City, Telecommunications Section of Wang Puppet Security Headquarters. There are three death files on Shen Jingzhe's desk: Within two months, three latent comrades were executed by Masao Yamada due to "accidental" exposure. No one knew that a deduction was going on in the mind of this frail major - the data in every file, the micro-expressions of every witness, and the overlapping probability of every patrol route. When Masao Yamada threw the fourth "suspect list" in front of him, Shen Jingzhe closed the file and said, "Taijun, Sakurako Watanabe from the seventh class next to you bought an extra pound of glutinous rice at the rice store three days ago." Yamada's pupils shrank suddenly. That pound of glutinous rice is a symbol of conveying information. Shen Jingzhe knew that only by betraying her could he save the entire network. But the result of the deduction went awry - before her death, Watanabe Sakurako identified another hidden line. The traffic officer named Lin Xiulan was holding an eight-year-old child in her arms. Shen Jingzhe must execute the execution himself. His logic told him: fire one shot and two hundred people will live. But he didn't expect that the child's eyes would stare at him and remember him for a lifetime. Tonight, the turret is going to explode. Does he want to portray himself as a murderer or a hero?
