 Soon, Erzhu Tianguang took his army to converge with Erzhu Zhao, and Erzhu Shilong's brothers Erzhu Dulü (爾朱度律) and Erzhu Zhongyuan (爾朱仲遠) at the important city Yecheng, which Gao had taken earlier in 532.Despite numerical advantage, however, Gao defeated them, and Erzhu Zhao fled back to Jinyang (晉陽, in modern Taiyuan, Shanxi), while Erzhu Zhongyuan fled back to Huatai (滑台, in modern Anyang, Henan).Erzhu Tianguang and Erzhu Dulü retreated toward Luoyang, but Husi rebelled at this time, seizing the fortress of Beizhong (北中, just north of Luoyang across the Yellow River), and when Erzhu Dulü and Erzhu Tianguang failed to recapture Beizhong, they were forced to flee, and they were captured and delivered to Husi, who in turn delivered them, as well as the heads of Erzhu Shilong and Erzhu Shilong's brother Erzhu Yanbo (爾朱彥伯) (whom Husi had earlier captured and executed) to Gao.
