Undercover in Japan: Making Money and Fighting the War Behind Enemy Lines

In 1937, Chinese student Wu Yixuan, who had studied in Japan, is trapped in an enemy country by the war, forced to watch his compatriots massacred and his homeland trampled. No money to get home? Then he'll steal theirs! Using an assumed name, he infiltrates a Japanese town and gets by through charming all kinds of Japanese women: an army quartermaster's widowed wife, a spinning-mill worker, the local elementary schoolteacher... They give him money and gifts and trust him with their hearts, never realizing that every penny he swindles from them and every piece of information he steals will be turned into bullets and food, secretly sent back to his homeland. The Japanese look down on the Chinese? Then he'll turn their money and their trust into shells fired right back at them! Deep in enemy territory, he delivers the harshest revenge on the invaders by the most secretive means!
