Meanwhile, at Cha Wenhui's request, Li Jing sent additional troops to reinforce his army to again prepare to attack Jian. Wang sent Yang Sigong and Chen Wang to resist. Chen initially took a defensive posture and set up his defense on a river, and the Southern Tang army did not dare to attack. However, Yang, stating that it was Wang Yanzheng's order, insisted that Chen attack. Chen was forced to attack the Southern Tang army, and fell into a trap set by the Southern Tang general Zu Quan'en (). Chen was killed, and Yang was forced to flee back to Jian. Hearing of this, Wang Yanzheng panicked, summoned additional troops from Quan (commanded by Dong Si'an and Wang Zhongshun) to reinforce Jian's defenses, and prepared for a siege. It was said that the people of Jian, tired of the warfare among the Wang clan members and the heavy-handed rule imposed by Yang, were welcoming the Southern Tang army and opening roads for them.
