Xue Rengui
After defeat of Ashina Funian, he left for the Mongolian steppe, from where he raised an army of 17 generals and 5,000 men. He started with an attack on Huige in 681. He reconquered most of the lands of the first Eastern Turkic Khaganate, founding the Second Turkic Khaganate. In 682 Xue Rengui was commissioned to attack Ashide Yuanzhen, now an aide of Ilterish. His presence intimidated Tujue soldiers, who had thought that he was long dead, and he scored a major victory over Ashide Yuanzhen.
