After the battle in the Ming Realm, the Main Dao knew what had happened. Time Gui had ambushed Lu Yin, and Ming Qing and Saint Rou must have known about it. If the ambush had succeeded, they would have immediately attacked Xiang City. But now that it had failed, Bu Qing and Snow Queen were the price.
