Da Qin: I Vow Not to Take a Step Back When My Father Dies.

The First Emperor died in the sand dunes, and the Huns' dog army and Wuhuan's 200,000 cavalry pressed down on Yanmen. Fu Su wears armor and holds a sword: "My father has been dead for a long time, and this pass is like losing the Central Plains." Fifty thousand remnant troops fought bloody battles for seven days, and the bones formed a city wall. The enemy leader sneered from the high platform. I raised my bow and nocked an arrow: After shooting this one, you will guard the pass.
