During a cross-border anti-terrorism mission, the top modern soldier Wang Lingyun encountered time and space turbulence. Carrying compressed food, tactical daggers and damaged individual soldier communication equipment, he accidentally traveled to the chaotic battlefield in the late stages of the Songhu Battle in 1937. As soon as he landed, he witnessed the Japanese army massacring a village. With his fighting skills and battlefield judgment far beyond his time, he rescued the surviving young man Chen Xiaohu and killed the Japanese army for the first time.
