The protagonist in modern society, Li Hao, is a typical street gangster. He is a good talker and lives a free and unrestrained life. However, something unexpected happened. He died accidentally in a "life and death duel" and was suddenly reborn in 1937, just as the Anti-Japanese War broke out. Li Hao became a Kuomintang agent, but his usual dawdling style did not change. This "gangster agent" immediately launched a story of resistance against Japan that was both humorous and full of wits and courage.
