In October of the fifteenth year of Xiantong, the west city on the north bank of the Xihetao was surrendered.

The Tang Dynasty established the Three Surrender Cities on the north bank of Hebei, also known as the Three Cities Outside the River. The three cities were subordinate to the Tiande Army and the Zhenwu Army, of which the west city belonged to the Tiande Army, and the middle city and the east city belonged to the Zhenwu Army. Although the three surrendered cities were named "surrendered", they were not built to accept the surrender of the Turkic nobles, but were stationed outside the city group, and formed a defense system inside and outside the Hetao in the middle and late Tang Dynasty with the surrounding military towns and prefectures.

The three cities were built in the time of Zhongzong, and it took only two months before and after.

During the reign of Emperor Zhongzong of the Tang Dynasty, the destroyed Turks restored the country, and often Koubian, and the imperial court built three surrendered cities on the north bank of the Hetao to defend. The city of Zhongshou is located in the location of the Fuyun Temple, southwest of Baotou City, Inner Mongolia. The eastern surrendered city is in present-day Inner Mongolia Tuoketuo, and the western surrendered city is in the southwest of the United Banner of the Central and Later Urad in present-day Inner Mongolia, each of which is 400 miles away from the surrendered city. He also set up 1,800 beacons in the northeast of Niutou Chaona Mountain (in the east of present-day Guyang, Inner Mongolia) in the northeast of Zhongshou City, and vigilantly monitored the movements of the Turks and transmitted news in a timely manner.

The city of Xishou, referred to as Xicheng, was subordinated to the Tiande Army after 796. Xicheng is located in the south of the mountain pass of Jilang Mountain in Shilan, Inner Mongolia, and the ferry port on the north bank of the Yellow River. At the beginning of the city's construction, the Anbei Metropolitan Protectorate moved into the city from Xi'an City in the Hexi Corridor.

Xicheng was eroded by the diversion of the Yellow River decades ago, but only after Yu Xuan took office. And please draw money and grain to restore the western city. After Yu Xuan arrived. Repair the city of the West Surrender. And please reopen the Xicheng border city, and exchange markets with the grassland Hu people and silk horses. Due to the opening of the new mutual market, Xicheng has become prosperous again.

At present, Xicheng has a population of more than 50,000 people, including 7,000 Tiande soldiers and 2,000 war horses.

The west city is a double layer, and there is an inner city in the outer city, which the locals call a big city and a small city.

At this time, the capital defense envoy in the small city. It has just been replaced with the brand of the Tiande Army's Jiedu Envoy, and the Shuangjing Shuangjie given by the Son of Heaven from Chang'an has also been sent together with the holy decree.

The commander of the Tiande Army was upgraded to the rank of Jiedu Envoy in Xuan's defense envoy, and the number of troops of the Tiande Army has also increased by 3,000, and the Tiande Army now has 10,000 soldiers. These days, the Tiande Army is setting up a recruitment banner and is constantly recruiting new recruits.

In the Shuaifu Festival Hall, Yu Xuanzheng had just received a letter from his protégé Li Jing.

Since Dengzhou came to Tiandejun to take up his post. Yu Xuan and Li Jing are not much apart. Li Jing, a protégé, still makes Yu Xuan very satisfied, and he usually writes constantly. And the gifts are even more. Not only is it indispensable to celebrate the festival every year, but also if it is not a festival, there will always be a batch of gifts delivered every other month and a half and twenty days.

Today, along with this letter, there are three thousand taels of gold, as well as a lot of silk and silk. After Yu Xuan arrived in the Tiande Army, he was able to move back from Beicheng to Xishou City, and he relied on the money sent by Li Jing several times, which helped him a lot. Otherwise, relying on the imperial court alone, it would be impossible for the city to be repaired so quickly. Moreover, after the exchange of markets, Li Jing let the caravan send a lot of goods, attracting many Hu nobles from the grassland to trade. As a result, the city of Xishou became more and more lively, and the Tiande army also received a large amount of taxes, and the food and salary rewards owed by the soldiers of the Tiande army were also repaid.

"Dashuai, Dengzhou has sent gifts again, Dashuai's protégé is really filial." The chief of Tuyuhun and the governor of Yinshan Helian Duo stepped into the festival hall with a hearty laugh.

Yu Xuan smiled and got up to greet him: "Governor Hao Liandu came just in time, and Ben Shuai has something to discuss with you." ”

Helian Duo was more than seven feet tall, with a tiger's back and a bear's waist, and a square face that was blackened and somewhat purple by the wind, and he always laughed at all times, and his laughter was very hearty. Coming in with him was Bai Yicheng, another chief of Tuyuhun. Bai Yicheng is also the chief of Tuyuhun, but he has to be thinner. Both of them were dressed in Tang dress, robes and boots, and there was no sense of Hu Ren from the outfits.

"Dashuai has such a good protégé, it really makes us envious, I don't know what kind of gifts did Lu Dao give this time?" Bai Yicheng said with a smile, and naturally found a place to sit down at random.

"Ji Yugang sent three thousand taels of gold, and there is also a batch of Jinchuang hemostasis and other medicines." Yu Xuan and them are also very familiar with each other, and they have a good relationship, and they have no concealment at the moment.

Three thousand taels of gold, Helian Duo and the others were a little surprised when they heard this. Yu Xuan's protégé is really envious of them, three thousand taels of gold can be exchanged for at least more than 20,000 copper coins. More than 20,000 yuan, even if they are chiefs, this is not a small amount. What's more, this gift is not the first time, Yu Xuan doesn't know how many times Lu Dao has received it, and which gift is not both elaborate and precious. After all, there is no gift less than 10,000 yuan each time.

"Ji Yu is indeed a good protégé, the old man didn't lose his eyes at the beginning." Yu Xuan smiled and pushed a gift slip in front of the two.

Helian Duo picked it up and looked at it, and saw that the gift said three thousand taels of gold, and there was a list under the gift list. But it was a check marked with the Four Seas Bank, the amount of three thousand taels of gold. At the moment, he couldn't help but be stunned, he was clear about this Sihai Money Village. When Yu Xuan wanted to set up a city in Xicheng, his protégé Li Jing organized a large number of goods to be sent to Xicheng, all of which were rare and in demand. And then also opened dozens of large and small stores in Xicheng, dealing in a variety of goods sent from Dengzhou. In addition to those shops, they also opened a money bank in the world. It not only operates the cash business of the counter, but also provides this kind of check business that is more convenient than the cash flying.

Just one look at the check made it clear to him that it was genuine. With this piece of paper, he was able to take three thousand taels of gold out of the bank. It's just that he doesn't quite understand that this gold was just sent to him by Yu Xuan's disciple Li Jing, why Yu Xuan wants to 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. But in fact, they are not directly under the command of the Tiande Army, Tuyuhun has its own Yinshan Governor, and they also have their own soldiers and horses. During the Tang Dynasty's wars, the Tang Dynasty often called them to send troops, which was more similar in nature to the nature of mercenaries. Help the Tang Dynasty fight, and the Tang Dynasty will give rewards. In normal times, the Tang Dynasty didn't care about them, and naturally there would be no money, food, and military salaries.

Yu Xuan pushed the check that Helian Duo pushed back again, and said slowly, "Inviting the two of you here this time is actually something important to ask for." Li Guochang of the Shatuo clan and his son made a rebellion, and the two should also know the Tao. To tell the truth, at present, the imperial court transferred Zheng Cong Xiangguo to serve as the envoy and Taiyuan Mansion Yin, the northern capital stayed behind, and the Hedong Jiedu envoy was posted. The original recruit made Li Jun have been demoted to the capital of the southern camp. And Ben Shuai, the imperial court has summoned me to be the commander of the camp in the west. In addition, my protégé Ji Yu has also led his troops from Youzhou to Datong, and is now serving as the commander of the eastern camp. “

Helianduo and the others nodded, they were naturally clear about these situations. As soon as Li Guochang rebelled, Yu Xuan had already summoned them to gather 6,000 soldiers and horses to deploy on the border with the Zhenwu army, which made Li Guochang's original plan to seize the Tiande army frustrated.

"The current situation is that Li Guochang has suddenly led his troops to Youzhou to attack Tuoba Sigong, the leader of the party who has claimed to be the assassin of Youzhou since this year. And Li Keyong, the son of Li Guochang, failed to attack the Ningwu army in Lulongfu Prefecture before, and now he has captured the land of Daibei, and has Chen Bing Tianmen Pass in the north of Taiyuan, and confronted the five-way soldiers and horses led by Zheng Xiangguo. ”

Helian Duo and Bai Yicheng glanced at each other, although these two were both chiefs, they were actually respected by Helian Duo, and Bai Yicheng was more of a strategist. After hearing so much, Bai Yicheng almost heard some meaning, and asked directly: "Yu Gong is sent, I will not give up until I die!" ”

He had already guessed that Yu Xuan might be planning to ask them to send troops to deal with the Shatuo people. In battle, the Tuyuhun people are not afraid. Even if it is the famous Shatuo people in the late Tang Dynasty, they are not afraid of the Tuyuhun people at all. What's more, although they and Yu Xuan have not been friends for a long time, they believe that Yu Xuan is a person who is worthy of trust. What's more, Yu Xuan had just sent three thousand taels of gold.

Three thousand taels of gold, if three thousand Tuyuhun soldiers are mobilized to go on the expedition, each person can get one tael on his head, this is eight guan money, at the foot of Yin Mountain, on the north bank of Xitao, this is not a small amount of money. What's more, the greatest gain from fighting a war is looting and captured booty. Without the mobilization of soldiers and horses in the Tang Dynasty, the Tuyuhun people did not dare to rob casually.

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

The military offices of Li Guochang and his son were pointed out on the map, and the current positions and situations of the departments of the two sides were explained one by one. Yu Xuan asked Helian Duo: "Does the governor think this situation is very beneficial to us?" ”

After listening to Yu Xuan's explanation, Helianduo's eyes lit up. If what Yu Xuan said is true, then the soldiers and horses of the seven towns of the imperial court will be surrounded by Li Guochang and his son in three ways. But the territory of Li Guochang's father and son was originally separated by a Yellow River in the middle, one on the west bank and the other on the east bank. But Li Guochang still has to go south to fight Youzhou.

As a result, Li Guochang went south, and his lair was empty in the Duhu Mansion alone. Similarly, the Datong nest used by Li Ke is just as empty.

The Tiande Army and the Zhendong Army are one west and one east, and the current position can be said to be absolute. As long as he makes a move, he can put this Shatuo father and son to death.

"Yu Gong, just hand over the Tuyuhun cavalry to us in the Duhu Mansion, I only need to lead 3,000 cavalry from my headquarters to take Li Guochang's lair!" Helianduo said with excitement in his eyes. The Shatuo tribe should die, and he Tuyuhun tribe should be prosperous! (To be continued......)
