After Chu's fall, he briefly continued to hold control of Chu's Jingjiang Circuit (靜江, headquartered in modern Guilin, Guangxi) before abandoning it in face of a Southern Han attack, allowing Southern Han to seize control of the circuit.
Ma Xiyin secretly summoned the general Xu Keqiong, who was then serving as the prefect of Meng Prefecture (蒙州, in modern Wuzhou, Guangxi), to come to Gui to oppose Peng with him.
Xu thereafter arrived at Gui and defeated Peng in battle; Peng abandoned Gui and fled to Hengshan (衡山, in modern Hengyang, Hunan), where Ma Xi'e was at that time after being overthrown by another brother, Ma Xichong.
[1] Xu Keqiong's abandoning of Meng allowed Wu Huai'en to seize it, and then approach Gui, pillaging the territory of Jingjiang.
I have launched an army to head toward you by both water and land, and I will surely let you, Uncle Chancellor, always have a military command and always control territory.Ma Xiyin considered surrendering to Southern Han, but could not decide immediately.
