Wen Xingzhi indeed did not lose his head over the fall of Liangzhou City, but as Yan Qing had predicted, he was in desperate need of supplies.
Therefore, even though he knew that Ling Hua's hundred thousand troops were trailing Yan Qing's hundred and fifty thousand troops from behind, he calculated the time, noting that there was only a half-day's distance between them, which was not enough for Ling Hua to join forces with Yan Qing. With his two hundred and eighty thousand troops, he could certainly defeat Yan Qing's forces, even if Yan Qing was a skilled fighter. Two against one meant certain victory.
Thus, Wen Xingzhi pursued them.
Upon receiving a report that the Youzhou Army had arrived, Ling Hua smiled and said to Yan Qing, "Brother, as expected, your foresight is uncanny."
