Bai Xiao stayed at the hotpot restaurant until almost ten o'clock but did not see An Zhiyuan and Jiang Shaoqing; it seemed that the two hadn't found Shang Kaijie yet.
All of Shang Kaijie's capital was in the Capital City, and even though he was a wastrel, he should understand that only by returning to the Capital City could he be safe. Therefore, Shang Kaijie must be trying to find a way to return to the Capital City right now; he couldn't afford to offend Jiang Shaoqing nor An Zhiyuan.
Thus, not running away was absolutely impossible.
