Ying Zheng’s surprise attack to reclaim the throne has begun. While he and a number of his own men, along with the Mountain People, keep attention on themselves at the steps of the palace, the real attack is underway, with Xin leading a separate force of Diao, Bi, a few Qin soldiers, and more Mountain People through an escape tunnel to the throne room. Their goal? Capture Cheng Jiao and remove him from the throne while the main force acts as a distraction. But Cheng Jiao is prepared and not going down without a fight, and soon Xin’s team is met with monstrous foes!
