In the autumn of 1939, Linjiang City. Su Xu, the adjutant of the Third Battalion of the Puppet Army Security Corps, ostensibly collected food and collected donations for the Japanese army, but secretly put the fortifications on the cigarette box. Qiao Shouye had been watching him for three days - this brigade deputy was too clean to make money, something was wrong. Major Yamada was more direct and slapped the family list of everyone in Su Xu's team on the table: "Su Sang, sit down together. You know." Su Xu smiled and handed over the cigarette, thinking about the sketch of an improved grenade in his sleeve. The drawing was only as big as a palm, and if he drew a wrong line, he was not the only one who died. In the first test firing, the artillery shell exploded three feet outside the Japanese stronghold. Yamada was furious and wanted to shoot him, but Su Xu took the initiative to ask Ying to change the situation. The second time, the shells accurately filled the machine gun holes. Yamada patted him on the shoulder and called him "the pillar of the empire", but Qiao Shouye's face turned pale - he found out that this adjutant had a relationship with the military commander outside the city. Su Xu crushed the cigarette butt and said only one sentence to the comrades on the line: "The drawings can be revised three times. After three times, either Yamada will be sent away or I will be sent away." But he didn't know that his brother had already led the anti-traitor team into the city and wanted to personally kill him, the "traitor."
