fell, and Murong Bao and Murong Sheng were forced to flee to Jicheng. Murong Sheng's father-in-law Lan Han then took control of Longcheng and offered to welcome Murong Bao back. Murong Sheng, not trusting his father-in-law, advised his father to secretly advance south to try to join forces with his granduncle Murong De, who had been still defending Yecheng, not realizing that by that point Murong De had abandoned Yecheng and regrouped at Huatai (滑台, in modern Anyang, Henan) and declared his own independent state of Southern Yan.

Murong Sheng and Murong Qi then conspired for Murong Qi to flee out of the city and start an uprising. Murong Sheng, meanwhile, suggested to Lan Han that Lan Ti, not himself, was behind Murong Qi's rebellion. Further, at this time, because of a severe drought, Lan Han went to pray to the
