It was once one of the eight major tribes of Momeng, which had been passed down for hundreds of years, but in Tuo'an's father's generation, it began to decline, and was finally conquered by the Naiban tribe, and the tribe was scattered and returned to those tribes who were heartily with the Naiban tribe.

In the ninth year of Xianping, the Naiman Department unified the entire Momeng grassland in a real sense, and hundreds of Momeng tribes submitted to the Naiman Ministry, which continued for thousands of years of the Chai Book Rite election Khan system, was abolished, and the position of the Khan, from now on, there will be a hereditary leader of the Naiman Department.

It was also in this year that Tuo'an's mother, in prison, gave birth to Tuo'an, in the grassland, the Hu tribe's battle is extremely tragic, has always been to cut the grass and eradicate the roots, leaving no future troubles, Datou Khan was originally going to execute Tuo'an's mother and son, is the leader of the Wacker department, the father of the servant shot interceded for him, which saved his life, and adopted as a righteous son, personally taught and raised.

Three years later, Xizong died, Pingzong succeeded to the throne, and at this time, from Wuzong's Zhongxing, but just more than 30 years have passed, the Jin Dynasty's national strength is still strong, the strong and unified Momeng, several times to the south, are successfully resisted by the Jin Dynasty, during the period, the Jin Dynasty relied on the powerful forbidden army and the commander of the famous generals, several large-scale counterattacks, but in the end, no one on both sides can help anyone, can only compromise, calm down, wait for the opportunity.

In the twenty-fifth year of Datong, Pingzong conquered six towns in Hebei in the north, and finally ended in a fiasco, hundreds of thousands of elite forbidden troops were killed and wounded, and the country declined greatly.

Pingzong was defeated in Hebei, Anbei's troops retreated south to quell the chaos, a series of good news spread to Momeng, just inherited the throne of the Khan, the young Arislan, for a time ambitious, intended to reorganize the army to the south again, and invaded the Jin Dynasty on a large scale, but unfortunately Azhislan was too young and ignorant, he didn't know at all that the tribes of the Momeng grassland at this time had been separated from him, and there was already an undercurrent surging inside.

The reason is still out of the selfishness of the two generations of Khans before Arislan, the Naiban Department is to take advantage of a series of wars between the eight tribes and the Jin Dynasty, after heavy losses, this is the development and growth, and finally replace, the lessons of the previous car, the overthrow of the rear car, so after the unification of the head of the desert, several wars with the Jin Dynasty are all half-lure, half-threatening ways, forcibly gather many tribes, let them take the lead, and the Jin Dynasty to fight hard, its headquarters Naiban Department, but in the rear to supervise the formation, the battle situation is favorable, is to step forward to help the war, Take the opportunity to occupy the greatest interests, if the battle situation is unfavorable, it is the first to retreat and escape, several big battles, the Momenghu people have suffered heavy casualties, but their Naiman tribe has suffered little loss, which has led to great dissatisfaction of many tribes, but it is only taken by the strong and obscene power of the Naiban tribe, so they have to endure it, once the opportunity comes, they will definitely make a move.

The opportunity was not long in coming.

Azhislan's father is named Omugo, Omugo has a sibling brother named Gandi, this person is very capable and good at fighting, loyal to him, and has made great achievements, Omugo has repeatedly stated in front of everyone that after his death, the position of Khan should be inherited by his brother, but the fact is that Omugo finally passed the position of Khan to his son Arislan, Omugo was afraid that after his death, Gandi would rise up and rob his son of the throne of Khan, so before he died, he was divided into Monan, and let him not ride a horse, but to go in an ox cart, which is a great insult in the Hu tribe, Gandy was angry and angry, went on a hunger strike, and his son, seeing all this, vowed to avenge his father and seek justice, this man is a servant.

At this time, Anbei and Longyou Jiedu envoy is Liu Wei, he is very clear about the situation in Momeng, when Arislan gathered troops to go south to Anbei, he sent people to the depths of Momeng, found the servant shooting, and persuaded him to establish himself as the king, the servant shooting and Azhislan have a grudge against their father, the two have a deep grudge, both look at each other unpleasantly, the servant knows that sooner or later one day, Arislan will definitely murder himself, at this time Arislan led the main force of the Hu tribe to the south, the internal emptiness, it is a great opportunity to act, how can you miss it.

While sending people to contact the major tribes and clarify their wishes, he burned wood to worship the heavens in Monan and established himself as Khan.

As soon as the news of the self-establishment of the Khan spread, the group responded immediately, and hundreds of tribes in the entire Monan expressed their willingness to surrender, and then, the servant led an army of 200,000 to kill in the north of the desert.

Arislan, who was commanding the battle on the front line of Anbei, was shocked when he learned that he had established himself as a khan and led his army to attack his old nest Mobei.

This civil strife, lasted for several years, Arislan succeeded, but also failed, he successfully shot the servant back, stabilized the situation of the entire Mobei, but he also failed, led the army to attack Monan, wanted to completely exterminate the servant, but could not be attacked for a long time, at this time, the civil strife of the Jin Dynasty has subsided, Pingzong died, the new emperor Zhao Zhi succeeded to the throne, Liu Ji, who has been the left minister, strongly persuaded Zhao Zhi to send a forbidden army, strengthen the military force of Anbei, and contain Arislan from behind, Zhao Zhi, who has just succeeded to the throne, is also extremely courageous, agreed to Liu Wei's suggestion, appointed Li Zhong as the envoy of the Anbei Festival, and led the few remaining 30,000 forbidden troops to enter Anbei.

The young and vigorous Li Zhong led 20,000 cavalry, thousands of miles to attack, directly attacking the lair of Arislan, although it was not successful, but also forced Arislan to withdraw from the south of the desert, since then, the three forces into a three-legged situation, each other containment, the desert grassland was officially split into the north and south of the desert two major Hu forces.
