Juqu Mengxun
However, Juqu Mengxun soon arrived, and he built levees to accumulate water around Dunhuang. Li Xun offered to surrender, but Juqu Mengxun refused. At this point, Song Cheng betrayed him and offered the city to Juqu Mengxun. Upon hearing this, Li Xun committed suicide, and Juqu Mengxun slaughtered the city. Western Liang was at its end.
