Subsequently, Gao defeated the combined forces of the Erzhus, and after the Erzhus' defeat, Husi and the generals Jia Xiandu (賈顯度) and Jia Xianzhi (賈顯智) quickly arrived back at Luoyang first and declared a revolt against the Erzhus, killing Erzhu Shilong and Erzhu Shilong's brother Erzhu Yanbo (爾朱彥伯), while capturing Erzhu Tianguang and another brother of Erzhu Shilong's, Erzhu Dulü (爾朱度律), delivering them to Gao. Gao had them beheaded. Gao, who had declared another distant member of the Yuan clan, Yuan Lang, emperor during his rebellion against the Erzhus, now believed that due to Yuan Lang's lineage, distant from recent emperors, he was not suitable to be emperor. He flirted with the ideas of allowing Emperor Jiemin to remain emperor or making Yue Yue, whom he welcomed back from Liang, emperor, but ultimately rejected both ideas. Instead, he had Husi seek out Emperor Xiaowen's grandson Yuan Xiu the Prince of Pingyang to offer him the throne. After some persuasion by Husi and Gao, Yuan Xiu accepted the throne (as Emperor Xiaowu). Emperor Xiaowu came to trust Husi Chun quickly and entrusted much governmental responsibility to him. Meanwhile, Husi Chun heard that Gao Huan executed two generals—Qiao Ning (喬寧) and Zhang Ziqi (張子期) -- accusing them of having first serving the Erzhus and then betraying them. Because he himself followed that pattern, he feared that he would be next, and therefore he, along with Emperor Xiaowu's close associate Wang Sizheng (王思政), suggested Emperor Xiaowu to try to find ways to free himself of Gao's grip on power. Under Husi's suggestion, Emperor Xiaowu tried to rebuild the imperial army, selecting the best soldiers for the army. Also under his suggestion, Emperor Xiaowu endeared himself to the general Heba Yue (賀拔岳, Heba Sheng's brother), who controlled the western provinces, and further commissioned Heba Sheng with the command of the southern provinces, intending to depend on the Hebas to resist Gao.
