The kingdom of the flower thorn submodule was originally a small country in the eastern part of the Caspian Sea, and its capital was Wugong Gechi (formerly known as the flower thorn submodule and Urda Chi, and the Mongols called it Yulong Jiechi, now in Urgenchi, Turkmenistan). In the sixth year of Song Qingyuan (1200), after Maha succeeded to the throne, he gradually became stronger and captured the western part of Liaoning. Through many expeditions, it annexed neighboring countries such as Persia (now Iran) and Afghanistan and reached its peak. Xindu was built in Samarkand (now Samarkand, Uzbekistan) in an attempt to explore Mongolia, and sent envoys to Zhongdu (now Beijing) to inquire about the actual situation and route of Mongolia. Since then, due to the enfeoffment of various factions, the national strength has gradually weakened.

In the 10th year of Yuan Taizu (12 15), Genghis Khan sent envoys to the kingdom of Huatuo Mozi to conclude a trade agreement. According to the agreement, Genghis Khan sent 450 envoys and caravans and 500 camels, carrying a lot of gold, silver, jewelry and commodities for trade. As for Ortera (a job is a thorn in the side, in the northwest of Chimkent, Kazakhstan), the governor also found it difficult to make a fortune, falsely accused the caravan of being a spy, reported to the king for slaughter, and embezzled goods and camels. In order to concentrate on attacking gold, avoid interrupting trade and strive for a peaceful solution, Genghis Khan sent envoys to Maha at the end of the book to accuse him of treachery and demand the surrender of the murderer. Mahamo refused to ask, killed the ambassador, shaved off the beards of the two ambassadors and escorted them out of the country.

Genghis Khan then paid Muqali to attack the gold and conquered the flower thorn submodule. In the 13th year (12 18), after the demise of the Western Liao Dynasty, the western border of Mongolia bordered the western regions. Fourteen years, Genghis Khan pro-unified army for five years. Destroy 400,000 troops and conquer the thorn submodule.
