Zhao Tiezhu wakes up to find himself time-traveling to the Three Kingdoms era, becoming a personal guard trapped defending Maicheng. Knowing history well, he is aware that Guan Yu taking the small path to break through will inevitably fall into Lü Meng's ambush, ending up beheaded. Seeing Guan Yu stubbornly taking risks, Zhao Tiezhu risks his life to remonstrate publicly and strongly urges changing the breakthrough route. Even avoiding the small path, the Wu army's inescapable net still closes in step by step. Fighting bloody battles to break through and Shangyong closing its gates to deny reinforcements, a group of people goes through life and death fleeing around. Holding historical spoilers in his hands, he defies heaven to shatter Eastern Wu's fatal scheme, trying his utmost just to bring Martial Saint Guan Yu alive out of the desperate situation.
