After transmigrating into the body of a female bandit, she refuses to rob, kill, and pillage. Instead, she builds asphalt roads and concrete stone bridges, openly charging travelers tolls! Using homemade firearms, she boldly fights off government forces, sees through the county deputy's sinister scheme, and becomes the target of a conspiracy in which he sacrifices 2,000 soldiers to frame her for rebellion. When 200,000 Northern Di cavalry descend upon the border, she sets aside old grudges and rushes to defend Yanmen Pass. Unveiling her arsenal of cutting-edge technological weapons, she takes out the enemy general from ten miles away. She does not fight for the imperial court's loyalty, but to protect the countless innocent people struggling to survive in a world plunged into chaos!
