Mu Huali is resolute and wise, his arms are like apes, he is good at riding and shooting, and he can hold a bow and two stones. He fought with Genghis Khan and was known for his loyalty and bravery. He once stood in the wind and snow with Borshu, supported the felt tent with his hands, shielded Genghis Khan, and did not move his feet from midnight to dawn. He once led a bow and shot a thief in a valley, and three arrows were killed to protect Genghis Khan out of the valley.
King Kereh Khan was at war with Naiman, and his army was unfavorable, so he asked Genghis Khan for help. Genghis Khan sent Mu Huali and Borshu to lead troops to the rescue. Mu Huali fought fiercely with the barbarian soldiers in the platform, and finally defeated the barbarian soldiers, and returned with a lot of armor and horses. Soon, King Kereh Khan, fearing that Genghis Khan's power was getting stronger, plotted to attack Genghis Khan. When Genghis Khan learned about it, he sent Muhua Lixuan's elite cavalry to attack the camp of King Kereh Khan at night, and Wang Khan's soldiers were defeated, and Wang Khan fled, and later died. The Kereh tribe was the most powerful of the Mongolian plateau tribes at that time, and the whole army of King Khan was defeated in this battle, and the other tribes shuddered and came to Genghis Khan. After Genghis Khan ascended the throne of the Great Khan, Feng Mu Huali and Borshu were the heads of ten thousand households.
After Genghis Khan unified the tribes of the Mongolian Plateau, he began to plan an attack on the Jin Dynasty in order to remove this obstacle to advancing into the Central Plains and moving south to the south of the Yangtze River. In March of the fourth year of Jiading in the Southern Song Dynasty (1211), Genghis Khan sent Mu Huali and other generals to the south. When the Mongol army was in high morale, it went south, first Kedexing (now Zhuolu, Hebei), then pulled Yunzhong (now Datong, Shanxi), Jiuyuan (now Wuyuan, Inner Mongolia), and entered Fuzhou (now Zhangbei, Hebei). The Jin soldiers claimed to be 400,000 and lined up in the north of Yehuling (now northwest of Wanquan, Hebei). Mu Huali led the charge into the enemy line, and the Mongol cavalry then rushed over. Genghis Khan also commanded the Zhulu army and attacked the Jin soldiers. The Jin army was in disarray, unable to resist, so they retreated. The Mongolian army chased to the Huhe Fort, and it was another period of cover-up, and the Jin army claimed that 400,000 military horses were killed at this time, and the zombies were hundreds of miles. In this battle, the Mongol army won more with less and defeated the Jin army with a big victory.
Jinzhou (now Jinzhou, Liaoning) Zhang Whale gathered more than 100,000 people, killed the envoy of the Golden Festival, called the king of Linhai County, and came to descend to Mu Huali. Genghis Khan's edict was to be led by Zhang Whale to lead the Beijing Ten Commanders to control the troops and conquer the prefectures and counties that were not annexed to Mongolia from the south of the country. At this time, Mu Huali sensed that Zhang Whale had the intention of rebellion, so he ordered his general Xiao Ye to supervise his army first. He and Zhang Whale tried to escape, but they were taken by Xiao Ye first and sent to Genghis Khan, where they were immediately killed.
When Zhang Zhi, his younger brother, heard that his brother had been killed, he was angry and occupied Jinzhou, betrayed the Mongols, and led his troops to capture Ping, Rui, Li, Yi, Guangning and other prefectures. Mu Huali led the Mongols to spend tens of thousands of troops to defeat Zhang Zhi. In the seventh year of Jiading (1214), Zhang Zhi led his troops to capture Xingzhong Mansion. In July, Mu Huali led his army to the city of Xingzhong. The Mongol army beheaded Zhang Dongping, the son of Zhang Whale, and more than 12,000 soldiers. Then he captured Kaiyi County and besieged Jinzhou. Zhang Zhi sent his subordinates Zhang Taiping and Gao Yi to fight, but they were all defeated. The Mongol army besieged Jinzhou for more than a month, and Zhang Zhi was resentful that his subordinate generals did not kill the enemy, so he killed more than 20 defeated generals. Gao Yi was afraid, so he took advantage of Zhang Zhi's unpreparedness and kidnapped him out of the city and surrendered. Mu Huali killed Zhang Zhi.
After the rebellion in Jinzhou was quelled, Mu Huali led his army south to attack Suzhou (now Suzhou, Jiangsu), Fuzhou (now Chuyang, Hubei) and Haizhou (now southwest of Lianyungang, Jiangsu).
