In 2005, North and South Korea jointly produced nuclear weapons, but under the pressure of international powers, the two Koreas had no choice but to surrender their nuclear weapons, and their desire for national prosperity was once again dashed. North Korean Major Jiang Min-ji (Kim Sung-woo) is unwilling to yield and takes Dr. Kim (Kong Hsiao-jin) and Flying Zhenlei, who are involved in the project. South Korea sends Major Park Zhengyu (Huang Zhengmin) to lead the pursuit, just when the two sides meet. A comet rowed across the sky, and under the influence of the powerful forces of comets such as Jiang and Park, they came to North Korea in 1572 by distorting time and space. Jiang, Park and others happened to deter the Nuzhen people who were slaughtering North Koreans, and was regarded as the "heavenly army" by the Korean ancestors. That night, a thief stole their weapons, and the thief was actually a North Korean national hero, Li Shunchen (Park Joong-hoon). At this time, Li Shunchen failed in the martial arts list and was in despair. In the face of frustrated national heroes and ancestors bullied by Nuzhen, the soldiers of the two Koreas who traveled through time and space began to fight for their respective beliefs.
