Li Changge, a modern novelist, traveled back in time to his own story of the 1960s. His family was originally surrounded by walls and suffered from hunger, but he had a Goldfinger one-dollar instant killing system. He only needed one dollar to kill ten thousand times of supplies every day. In this unique era, Li Changge relied on his system, wit, courage, and cautious character to gradually make his family live a good life. He married a wife and had children, and his life became happier and happier.
