It is said that once the Tang army relied on Xue Rengui who held the Great Revolution Seal to breach the Two Realms Pass, they stationed their troops there and ordered Qin Shubao to lead the right flank army to head westward to attack Peacock City.
Before the Two Realms Pass was breached, the Tianzhu army had approached with an army of three hundred thousand, but before they could enter the Two Realms Pass, news of its breach had arrived. This matter was no small concern, as the Two Realms Pass was as solid as a rock—let alone a million troops attacking it, even two million wouldn't have resulted in such a quick fall. Hence, the three hundred thousand troops stationed themselves within Peacock City, together with the city's defending army, totaling three hundred thirty thousand soldiers.
