Chu Cheng (), not knowing that assassins sent by Emperor Houfei's general Xiao Daocheng had already assassinated Liu Xiufan, seized Liu Zhun and surrendered Liu Zhun's headquarters to Liu Xiufan's army, claiming that Liu Xiufan had declared Liu Zhun to be his son. (Liu Xiufan himself made no such public declaration before his death.) However, when Liu Xiufan's army later found out that he was already dead, it collapsed, and Liu Zhun was not harmed. By 477, Emperor Houfei had shown himself to be a cruel and violent ruler, often roving outside the palace with his guards and killing any person or animal that they encountered. Xiao, in fear of being killed by Emperor Houfei, engaged his associates to have him assassinated, and then used his personal control of the army to effectively force other high-level officials Yuan Can and Liu Bing to grant him near-imperial powers. He then made Liu Zhun emperor (as Emperor Shun), but the 10-year-old emperor was little more than Xiao's puppet. Reign Upon hearing of Emperor Houfei's death, the general Shen Youzhi accused Xiao Daocheng of wanting to usurp the throne, and he started a rebellion from his Jing Province (荊州, modern central and western Hubei), although he then ill-advisedly became bogged down in his progress in sieging Yingcheng (郢城, in modern Wuhan, Hubei). Meanwhile, an attempted coup by Yuan Can and Liu Bing to seize back power for the imperial clan failed in late 477, and both Yuan and Liu Bing were killed, permitting Xiao to further consolidate his power. By spring 478, Shen also had been defeated, and he committed suicide. Xiao no longer had opposition. He began to have himself bestowed with higher and higher offices and honors, posturing himself for the throne. He was also gradually assassinating some of Emperor Shun's brothers. In winter 478, Emperor Shun created Xie Fanjing, the granddaughter of the official Xie Zhuang (), as his wife and empress. In 479, Xiao first had Emperor Shun create him the Duke of Qi and grant him the nine bestowments, and then create him the Prince of Qi. In summer 479, Xiao was prepared to seize the throne, and he prepared a ceremony at which Emperor Shun was to ascend a high platform and issue an edict giving the throne to him. However, the 12-year-old Emperor Shun was fearful, and he hid under a statue of a buddha, crying.
