The conditions for Zhangxin Khan's dismissal were favorable: the Uighurs recognized Yang Hao's control of the area south of Yinshan and east of Wolf Mountain; The Uighurs withdrew their forces from the Bolithic Fort; In exchange for one hundred taels of silver or equivalent items per person, Yang Hao added two additional items: first, the Uighurs severed their ties with the Quze tribe; 2. Restart the Tiande military trade route,

In order to show his sincerity and show that the Khan had first fulfilled his obligation to withdraw his troops from the Boulder Fort, the venue of the negotiations between the two sides was determined to be Dongsai Town, northwest of Yongfeng, and the Fengzhou side sent Li Tong as the chief negotiator, Zhuang Yunqing, Qu Qingquan, Huang Yiliang, Zhang Bozhong, and Wang Qun as members, and the chief negotiator on the Uighur side was Prime Minister Chai Ge, and his deputy was Chang An Yunhe, the head of the Longwei Right Brigade.

The confrontation at the negotiating table was quite fierce, and Chaig belonged to the moderate faction in the Uighurs, who was not accustomed to the weakness of the doves, nor did he want to see the hawks dragging the khanate into the quagmire of war because of the hawks' toughness.

An Yunhe is much rougher, he is a staunch main battle faction, he can't tolerate the Uighur Khanate's loss to a border town of the Tang Dynasty, the fiasco of the Battle of Boulder Fort has become a piece of his heart, he is very tough at the negotiation table, An Yunhe's stubbornness angered Li Tong, Li Tong even overturned the table and shouted: "If you are not convinced, go to the battlefield and do it again." After Yang Hao learned of this situation, he sent Mu Lanqing to bring a sentence to the delegation: Li Tong is still the chief representative, but Zhuang Yunqing is mainly responsible; not to dwell too much on the details, to reach an agreement as soon as possible to end the state of hostilities with the Uighurs,

……

After resisting for seven days and seven nights in Shannan City, the barbarian blacks once broke through the east gate and entered the city, but they were immediately driven back, Yang Hao took the opportunity of the easing in the middle of the negotiations, and urgently ordered the Tiger Battalion, the Leopard Battalion, the Flying Tiger Battalion and the Fengya Battalion to cross the Wolf Mountain and quietly enter the territory of Yinshan County, at the same time, Cheng Keling and Yu Yanlu led the main force of the Qingshan Brigade to attack the Manhei homeland, Sui Crouching Tiger led the troops to Datongchuan, and joined with the broken camp of Suo to cut off the back road of the barbarian blacks, Guan Suo was ordered to go to the Vulture Department in person, after a threat and temptation, forced Jin Mili to promise to break the alliance with the five tribes of the barbarians and remain neutral,

Yang Hao quietly completed the encirclement of the barbarian blacks, but did not immediately start, he has his own considerations, although the total annihilation of the barbarian blacks can be powerful, but at the same time will also leave sequelae, the surrounding small and medium-sized tribes for their own safety, is likely to fall to the Uighur Khanate or the Khitans, which is bound to worsen the living environment of Fengzhou, on the contrary, if the five barbarian black tribes can be subdued, it will not only be like a tiger with wings, but also can avoid too much stimulation of the surrounding small and medium-sized tribes,

In order to be able to convince the barbarian blacks psychologically, Yang Hao decided to get a perfect victory at any cost, the barbarian blacks were afraid of pain and defeat, he summoned Ling Tong, Yu Chongchong, Guan Suo and Wang Qun who rushed back from Dongsai Town, discussed secretly for a day and a night behind closed doors, and formulated a plan to convince the barbarian blacks:

1. To conclude a secret agreement with the Uighurs to call up the five most elite thousand troops of the Tiger Guard to participate in the siege of the barbarian Negroes, and to this end certain concessions to the Uighurs in the exchange of prisoners,

2. Yu Chongchong led the main force of the Xining Army to strive for a perfect victory, making the name of "General Tian" a permanent and unforgettable memory for the barbarian blacks; Take the opportunity to expand the popularity of the Kulub heavy cavalry,

3. Resolutely suppress the brutal generals and soldiers who participated in the massacre of civilians, and ensure that the list of those suppressed is accurate, and that the crimes committed are detailed and reliable, and that they can withstand scrutiny.

Fourth, force the old man Wen to step down, choose the relatively mild Gulu Mangyue Great Elder (Prime Minister) Mei Lun as the leader of the five departments, and the barbarian old Wen, the old man, Gu Duoli and other militants moved to Feng'an under house arrest.

5. Fengzhou and the Mangyo Five Tribes concluded a secret covenant, and the Mangang Five Tribes were not allowed to enter into covenants with other tribes or local border towns in the Tang Dynasty without the permission of Fengzhou, and those that had been signed were immediately abolished.

Sixth, in the future, 100 outstanding young people will be accepted every year to study in Toyoshu, and all expenses will be borne by the Toyoshu government.

On the third day after the meeting, Zhuang Yunqing and Chai Ge reached an agreement on borrowing troops: with Chilu as the main commander, he led the 5,000 elite cavalry of the right team of the Tiger Guard, wearing the uniform of the Xining Army and secretly rushed to Yinshan County to stand by, Yang Hao transferred the armored infantry formation, the Kulubo heavy armored cavalry, the Modao team and the newly formed two longbow battalions to the Yinshan front line to listen to the use, and on the same day, Yang Hao appointed Yu Chongchong as the governor of Shannan, and unified command of all departments of the front line to participate in the siege of the barbarian blacks.

On the tenth day of the siege of the barbarian blacks, the naked five thousand elite horsemen suddenly appeared under the city of Shannan, at this time the oolong horse has been changed to the long hair of the winter, although it looks very thin, but the spirit is extremely excited, Yinshan County to Shannan City is nearly 100 miles apart, the oolong horse rushed to the battlefield in half a day, and immediately launched an attack on the barbarian blacks,

The old man was caught off guard, more than 6,000 people were suddenly washed away, and Gu Duoli was also washed away, as a general of the unified army, he had fought with the surrounding tribes for decades, and had never seen such a cavalry like wind and rain, he wondered if he was dazzled by a gust of wind, but the corpses on the ground told him that there was indeed a cavalry just now, and it was the Tang army wearing the Tang army uniform and waving the flag of the Xining army.

Kuluber's heavy cavalry then arrived, and under the cover of the cavalry of the Tiger and Leopard battalions, they launched a charge against the barbarian blacks who had just woken up from the chaos, and the rolling iron stream swept everything like a mountain and a sea, and the terrain around the south of the mountain was flat and open, which was very suitable for the charge of the heavy cavalry, and the advantages of the heavy cavalry were completely brought into play.

The barbarian blacks were dumbfounded, they had just been dizzy by the hurricane, and then they saw an iron wall pressed over, the horror in their hearts could be imagined, the only resistance was quickly crushed, and the only thing left for the barbarian blacks was to flee, but they soon found that the way to escape to the east had been cut off by the bare, and the soldiers of the tiger guard were not only good at swordsmanship, but also first-class riding and archery skills, if the barbarian blacks were not disrupted, they might still be able to fight, but now, they only had to turn their heads and continue to escape,

The west is Shannan City, there is no result in attacking for ten days, no one has time to try again at this moment, there is only one way to escape, go north into Mangmang Yin Mountain, there are twenty miles from Shannan City to Yin Mountain, the terrain is flat, there is a small river in the middle, the width of the small river is only more than ten zhang, the water depth is not a horse's knee, but both sides of the river are covered with a kind of thorns of "thorn sunflower hair", the highest "thorn sunflower hair" is about one zhang, the short one is three or four feet, the shape is like a thorn wall from a distance, people and horses can not cross,

At the beginning of the siege, Gu Duoli had the foresight to open a gap about 100 zhang wide by the river, in case of emergency, at this moment, this gap has become a life-saving "life gate", but what Gu Duoli did not expect is that Yu Chong Chong took the first step to seize this "life gate", Yu Chong Chong put the armored infantry formation at the forefront, the longbow battalion was separated from the left and right, and the longbow battalion was preceded by the Mo knife team.

At this moment, knowing that it is a trap, the old man and Gu Duoli can only jump down.

The barbarian blacks began a crazy rush to kill, hoping to open a gap from this, Yu Chongchong is worthy of being a great expert in the use of infantry troops, he did not use a cavalry, and the tortured barbarian blacks were exhausted, Yu Chongchong came forward, persuaded the barbarian old man, Gu Duoli to abandon the weapon and surrender, in order to save the remnants of the soldiers, the barbarian old man was desperate and had to admit defeat, dozens of small colonels held red flags and ordered the Quartet, and the name of "General Tian" suddenly resounded in the south of Yinshan,

Yu Chongchong concentrated the barbarian black soldiers who laid down their arms in the White Tiger Valley thirty miles west of Shannan City, and twelve high-ranking generals such as the barbarian Lao Mo and Gu Duoli were escorted to Feng'an, and at the same time, according to the list provided by the intelligence room, four hundred and thirty barbarian black soldiers and officers who participated in the massacre of the people were tried and sentenced outside the east gate of Shannan County, and then collectively beheaded for public display, and their heads were hung in the White Tiger Valley for three days and three nights.

On the day after the end of the Battle of Shannan, Cheng Keling and Yu Yan Furnace captured the hometown of the five tribes of Manhei, annihilated the defenders and captured Manlao Wen, according to Yang Hao's secret order, Cheng Keling forced the five ministers to remove the elder of Mangwen from the position of alliance ruler, and elected the elder of Gulu Mangyue to govern the alliance, Cheng Keling on behalf of Yang Hao invited Meilun to visit Fengzhou, and Meilun readily agreed.

Three days later, the eyebrow wheel and the other four leaders of the man's black set off to Feng'an under the "escort" of Yu Yanlu, along the way to greet everyone everywhere is flowers and applause, Yang Hao and the Fengzhou military and political leaders went out of the city twenty miles to meet the Meilun party, the guest and the host took a car into the city, both sides of the road are full of people who welcome the people, the eyebrow wheel and the four leaders are very moved,

That night, Yang Hao arranged a grand welcome banquet for the eyebrow wheel, the atmosphere was very harmonious, the four leaders of the bold personality even sang and danced on the spot, the eyebrow wheel made a toast and said: The barbarian black is the border state of the Tang Dynasty, the barbarian black people are the subjects of the Tang Dynasty, the barbarian black tribes are willing to be friendly with Fengzhou for generations, the barbarian Wen family provokes a war for their own selfishness, which is not tolerated by all the barbarian people, and the barbarian and black tribes are willing to strengthen exchanges and cooperation at all levels with Fengzhou,

Yang Hao made a toast saying: Fengzhou and the friendship of the Mangye tribes is tested by blood and fire, and any person and behavior who tries to destroy this friendship is doomed to failure, Fengzhou is willing to strengthen cooperation with the Mangye tribes in all aspects, and carefully maintain this hard-won friendship.

During the stay of Meilun and the leaders of the four departments in Fengzhou, they visited the cities, schools, factories, coal mines, farms and military camps in Feng'an, Fengzhou and other places, and the Meilun and the leaders of the four departments had been to the Tiande Army before, thinking that the prosperous place of the Han land was nothing more than that, and what they saw and heard in Fengzhou left a deep impression on everyone, which made them feel that the failure of the old man and Gu Duoli was not accidental, and the overall strength of the five departments of the barbarian black was not at the same level at all compared with Fengzhou,

With this foundation in place, in the ensuing negotiations, Meicha and the leaders of the four tribes accepted the terms proposed by Yang Hao almost in full, and on the same day, the Uighur envoys Chai Ge and Li Tong also reached the "Dongsai Town Agreement (Draft)":

1. The Uighurs recognized the south of Yinshan Mountain and the area east of Wolf Mountain as the jurisdiction of Fengzhou of the Tang Dynasty, and the people of all ethnic groups in both places were the people of the Tang Dynasty;

2. The two sides shall withdraw their troops from each other's territory and shall not violate each other's borders in the future;

3. All Uighur captives shall be returned to Fengzhou, and the Manu and their retinue slaves shall be resettled by the Fengzhou government if they wish to remain in the territory of the Tang Dynasty, and those who are willing to return to the Uighurs shall be redeemed by the original head of the family at the rate of thirty taels of silver or equivalent per person.

4. The Uighurs believed that the dispute between Toyosu and Quzebu over the purchase of horses was purely an internal affair of the two countries, and that the Great Uighur Khan would maintain a neutral and impartial attitude and would not interfere.

5. The Fengzhou government will assist the Uighur Great Khan in restarting the trade routes within the territory of the Tendean army; to facilitate the business of each other's merchants,

……

Half a month later, the Great Uighur Khan ratified the Tonsai Agreement.

In the same month, Yang Hao was appointed as the assassin of Fengzhou, and due to the death of Zhang Huchen, the position of the assassin of Fengzhou had been vacant for ten months.
