In October of the 15th year of Xiantong, Xishoujiang City on the north bank of Xihetao.

In the Tang Dynasty, the Three Sushoucheng City was established on the north bank of Hebei, also known as the Three Hewai City. The three cities belonged to the Tiande Army and the Zhenwu Army respectively. Among them, the Xicheng Returns to the Tiande Army, and the Zhongcheng Returns to the Zhenwu Army. Although the San Sushoucheng was named "Submission", it was not built to accept the surrender of the Turkic nobles. Instead, it was a group of guards stationed in the outer city, and with the surrounding military towns, the prefectures formed a defense system inside and outside Hetao in the middle and late Tang Dynasty.

The three cities were built during the reign of Emperor Zhongzong, and it took only two months.

During the reign of Emperor Zhongzong of Tang Dynasty, the destroyed Turkic Kingdom often invaded the border, and the imperial court built the Sanshoujiang City on the north bank of Hetao to defend. Zhongshoujiang City was located in the location of Fuyun Temple, southwest of Baotou City, Inner Mongolia. The east city was in Tokto, Inner Mongolia, and the west city was in the southwest of Zhongshoujiang United Banner, Urat, Inner Mongolia, and each was 400 miles away from Zhongshoujiang City. There were also 1,800 beacon towers north of Niutou Chaona Mountain (now east of Guyang, Inner Mongolia), to monitor the movements of the Turks vigilantly and convey messages in a timely manner.

Xishoujiang City, referred to as Xicheng, was divided into Tiande Army after 796. Xishoujiang City is located at the south of the Langshan Pass of Shilanjilang Mountain in Inner Mongolia and the ferry on the north bank of the Yellow River. It controls the key traffic between the north and south. Its military status is extremely important among the three Sujiang City. At the beginning of the city's founding, Anbei Protectorate moved into this city from Xi'an City in the Hexi Corridor.

Xicheng was eroded decades ago due to the diverting of the Yellow River. However, after Yu Jin took office, he asked to withdraw money and grain to restore Xicheng. After Yu Jin took office, he repaired Xicheng and asked to reopen the Xicheng border city to trade with the Hu people and silk horses on the grassland. As the new trading was opened, Xicheng became prosperous again.

At present, the population of Xicheng is more than 50,000. Among them, Tiande's army has a total of 7,000 troops and another 2,000 war horses.

Xishoujiang City is a two-story pass, and there is an inner city within the outer city, which the locals call it a big city and a small city.

At this time, the Duowei Guardian in the small town had just changed the sign of the Tiande Army Jieduan. The two flags and double ceremonies given by the emperor from Chang'an were also sent together with the imperial edict. At this time, the Jieduan erected six signs in front of the Jieduan yamen. Even the old yamen was re-expanded to meet the status of the Jiemaster's Mansion.

The chief general of the Tiande Army was promoted to the Jiedu Governor of the Gun Defence Envoy, and the Tiande Army's soldiers increased by 3,000. Now the Tiande Army has 10,000 troops. These days, the Tiande Army is raising the banner of recruiting soldiers and is constantly recruiting new soldiers.

In the Hall of the Shuai Mansion, Yu Yan had just received a letter from his disciple Li Jing.

Since Dengzhou came to Tiande Army to take office, Yu Guan and Li Jing have not been much distant. Li Jing's disciple was still very satisfied with Yu Guan. Not only did he write letters, but he also gave him a lot of gifts. Not only were he indispensable during festivals, but he was not only not a festival during festivals. After twenty days of the month and half, a batch of gifts will always be delivered.

Just today, with this letter, there were 3,000 taels of gold and a lot of silk and silk. After Yu Yan arrived at Rentian De Army, he could move back from the North City to Xishoujiang City, and he also relied on the money sent by Li Jing several times to help him. Otherwise, it would be impossible for Xishoujiang City to be repaired so quickly by relying on the imperial court to withdraw money. Moreover, after the trade, Li Jing asked the caravan to send a lot of goods, attracting many Hu nobles on the grassland to trade. The Xishoujiang City became more and more lively, and the Tiande Army also received a lot of taxes, and the food and salary owed by the Tiande Army soldiers were also reissued.

"Master, the gift from Dengzhou is here again. The student of Master is really filial." Chief Tuyuhun and the governor of Yinshan Helianduo stepped into the festival with a hearty laugh.

Yu Yan smiled and stood up to greet him: "Governor Hao Lian is here just right. I am discussing with you if I have something to do."

Helianduo was more than seven feet tall, with a tiger's back and a bear's waist, and a square face that was black and purple with a slight purple that was stuffed into the wind. No matter when, he always smiled and his laughter was very cheerful. Another chieftain of Tuyuhun was Bai Yicheng. Bai Yicheng, also the chief of Tuyuhun, was also a chief of Tuyuhun, but he wanted to be thinner. Both of them were dressed in Tang people and robes and boots, and there was no feeling of the Hu people in their outfits.

"We are really envious of the great coach who has such a good student. I wonder what kind of gifts I gave this time?" Bai Yicheng smiled, and naturally found a seat to sit down.

"Ji Yugang sent 3,000 taels of gold, and a batch of gold-cancerous hemorrhage-stop drugs." Yu Yan and they were also very familiar with each other, and had a good relationship, so they did not hide it at the moment.

Helian Duo was surprised to hear this. The disciple Yu Guan received was really envious. Three thousand taels of gold can be exchanged for at least 20,000 guan of copper coins. More than 20,000 guan, even if they are chiefs, this is not a decimal amount. What's more, this gift is not the first time. Yu Guan doesn't know how many times he has received, and which gift is not both meticulous and precious. In short, the gift is not less than 10,000 guan each time.

"Ji Yu is indeed a good disciple. I was not confused at the beginning." Yu Yan smiled and pushed a gift list in front of the two of them.

Helianduo picked it up and saw that the gift said 3,000 taels of gold was written on it, and there was a list under the gift list. It was a check marked with the Sihai Money House, with an amount of 3,000 taels of gold. He was stunned at the moment. When Yu Ren wanted to set up a city in Xijiangcheng, his disciple Li Jing organized a large number of goods to Xicheng, all of which were rare and intimate. He then opened dozens of shops of all sizes in Xicheng, operating various goods delivered from Dengzhou. In addition to those stores, they also opened a Sihai Money House. Not only did they operate the Feiqian business of the Cabinet, but also provided this kind of check business that was more convenient than Feiqian.

As soon as he looked at this check, he understood that it was real. With this piece of paper, he could immediately withdraw 3,000 taels of gold from the money house. But he didn't quite understand that this gold was sent to him by Yu Guan's disciple Li Jing, but why did Yu Guan give it to him now?

Although the Tuyuhun tribe lived in the south of Yinshan, most of them were under the jurisdiction of the Tiande Army. In fact, they did not directly belong to the commander of the Tiande Army. Tuyuhun had its own Yinshan governor, and they also had their own troops. During the war in the Tang Dynasty, the Tang Dynasty often summoned them to send troops, which was more similar to the nature of mercenaries. When they helped the Tang Dynasty fight, the Tang Dynasty gave rewards. In normal times, the Tang Dynasty did not care about them, and naturally they would not have money, food, and military salaries.

Yu Qin pushed the check that Helianduo pushed back and said slowly, "This time I invited you two to come, but there are actually important things to ask for. The two of them should know about the rebellion of Li Guochang and his son of Shatuo clan. They should not hide it. Now the court has transferred Zheng Cong-secretary to serve as the governor of the recruitment and the prefect of Taiyuan, and the Northern Capital is left behind and Hedong Jiedu. The original recruitment Li Jun has been demoted to the commander of the south camp. The court has called me to the commander of the west camp. In addition, my disciple Ji Yu has also led his troops from Youzhou to Datong, and is now serving as the commander of the east camp."

Helian Duo and the others nodded, and they were naturally clear about these situations. As soon as Li Guochang rebelled, Yu Guan had already summoned them to gather 6,000 troops to set up defenses on the border with the Zhenwu Army, which made Li Guochang's original intention of seizing the Tiande Army fail.

"The current situation is that Li Guochang has suddenly led his troops to Youzhou to attack Tuoba Sigong, the leader of the Dangxiang people who claimed to be the governor of Youzhou since this year. Li Keyong, the son of Li Guochang, had failed to attack the Ningwu army in Lulong and Guizhou. Now he has seized all the land in the north of Daiyuan and has already set up troops to confront the five troops led by Zheng Xiangguo."

Helianduo and Bai Yicheng looked at each other. Although these two were both chiefs, they actually regarded Helianduo as their respect, and Bai Yicheng was more of a role as a counselor. After hearing so much, Bai Yicheng had almost heard some of the meaning and asked directly: "Your Duke Yu is sent, so we will die!"

He had already guessed that Yu Quan might have planned to invite them to send troops to deal with the Shatu people. The Tuyuhun people were not afraid of the war. Even even the famous Shatu people in the late Tang Dynasty, they were not afraid of the Tuyuhun people. What's more, although they had not been with Yu Quan for a long time, they believed that Yu Quan was worthy of trusting cooperation. What's more, Yu Quan had just given 3,000 taels of gold.

If three thousand taels of gold are mobilized to go to war, each person can get one tael on his head. This is eight jin of coins. On the north bank of the western tael at the foot of Yinshan Mountain, this is a considerable amount of money. What's more, the biggest gain of war is the looting and seized spoils. Without the mobilization of the Tang Dynasty's soldiers, the Tuyuhun people usually dare not rob them casually.

Yu Yan smiled with satisfaction and slowly unfolded a map on the table.

The arrangements of the military offices of Li Guochang and his son were pointed out on the map, and the current location and situation of the departments of both sides were explained one by one. Yu Qin asked Helianduo: "The Governor thought this situation was very beneficial to us?"

After listening to Yu Vin's explanation, Helianduo's eyes shone. If what Yu Vin said was true, then the seven soldiers and horses in the court would be surrounded by Li Guochang and his son in three directions. However, the troops and horses of Li Guochang and his son were originally separated by a Yellow River in the middle, one on the west bank and the other on the east bank. But Li Guochang had to go south to attack Youzhou.

As a result, when Li Guochang went south, his old nest, the Shanyu Protectorate, became empty. Similarly, Li Keyong's Datong nest was also empty.

The Tiande Army and the Zhendong Army are one west and one east, and their current position can be said to be amazing. With just one move, the Shatuo and his son can be killed.
