but decided to continue the campaign anyway because he had superiority in numbers and his troops were well-trained. During the Battle of Shiting, Lu Xun remained in the central command, with Zhu Huan and Quan Cong leading the armies on his left and right flanks respectively. Their three armies advanced together and defeated Cao Xiu's forces lying in ambush and drove them further northward until Jiashi (). They killed and captured thousands of enemies and obtained much of the enemy's livestock, equipment and supplies. Cao Xiu died of illness after returning to Wei. Lu Xun and the victorious Wu forces returned to Wuchang (武昌; present-day Ezhou, Hubei), where Sun Quan held a grand reception for them. Sun Quan instructed his servants to shield Lu Xun with his imperial parasol when he entered or left the palace, and rewarded Lu Xun with many gifts.

When Lu Xun heard about it, he reprimanded Sun Lü sternly, "Marquis, you should be spending time reading the classics and enriching yourself with knowledge. Why are you doing this?"

Sun Song (孫松; Sun Yi's son), the Colonel of Trainee Archers (), who was one of Sun Quan's favourite relatives, allowed his men to fool around in camp and did not maintain good military discipline. Lu Xun punished Sun Song's subordinates by having their heads shaved. Xie Jing () admired Liu Yi's discourse on punishment before civility. Lu
