 During the invasion of Jin China, Muqali acted as Genghis Khan's second-in-command, and was promoted to Viceroy of China, and was entrusted with a great degree of autonomy once Genghis Khan departed to conquer Central Asia.Unlike many Mongol leaders who were willing to massacre to gain any advantage, Muqali usually attempted to convert foes into friends by more conciliatory means, and change the Mongol image in China.By the time of Ogedei's reign (1229-1241), he was viewed as the best of the extraordinarily talented pool of Mongol generals.
