Hangu Pass

· Six years ago, the female deputy general Shen Zheng was falsely accused of "collaborating with the enemy and betraying the country" and was exiled to the snowy plains. · Six years later, Beidi broke through the pass and there were no generals in the court. Shen Zheng led 300 "sin slaves" to attack the enemy camp at night and became famous in one battle. · She brought evidence to Beijing, overturned the case at court, and exposed the conspiracy of the old general and deputy general. · After the unjust case was revealed, she refused to accept a high position and returned to the border with a bone sentry camp, becoming a true "Guardian of the Country".
