In 1937, Wu Yixuan, a student studying in Japan, was trapped in an enemy country due to war. He watched helplessly as his compatriots were slaughtered and his homeland was trampled on. No money to return home? Then grab them!
He sneaked into a small Japanese town under a false name, and used a mask to get around various Japanese women - the widowed quartermaster's wife, the spinning lady in the factory, the elementary school teacher in the town... They gave money and gifts, heart and soul, but they didn't know that this "reliable man" in front of him was converting every penny defrauded from them and every piece of information stolen into bullets and food, and secretly sent back to the motherland.
Do the Japanese look down on the Chinese? Then let their money and their trust become cannonballs aimed at themselves! In the hinterland of the enemy's country, he used the most secretive method to give the invaders the cruelest revenge!
