When Zuo Zhong woke up, he found that he had traveled to Nanjing in 1936 and became a second lieutenant leader of the second team of the Intelligence Section of the Military Command Secret Service - a character with the same name as him in the play. Accompanying the time travel are the complete plot memories stored in his mind about all the trends of the world: from the Anti-Japanese War to the War of Liberation, he knows every historical node and the fate of every key figure.
Zuo Zhong didn't know why he traveled through time, but he soon realized a problem: the body he occupied was dealing with the three forces of the military, the Japanese puppets, and the underground party in the form of a "smiling tiger" - and the plot told him that going down this road was destined to be a dance on the edge of a cliff, and if he was not careful, he would be in an abyss.
He decided to imitate everything Zuo Zhong should do. Externally, he is Dai Li's most respected military commander, who hides a knife behind his smile, is good at backstabbing, and is good at calculations; internally, he is an underground party member lurking in the heart of the enemy. He uses "plot prediction" as his trump card to make the best choice at every life-and-death juncture.
But when the day came when the plot was rewritten, Zuo Zhong discovered that: what he thought was a replica was actually no longer just a replica.
