Yu Wenjing was indeed here. His subordinates were all elite troops from various camps. Under the leadership of the Nangongxi Mountain Camp, he walked around the mountain to the back of Guizhou City.

Once upon a time, the sea was invincible, but Wushan was not cloudy.

As for Xi Riyue who had been a prince or a governor of two states, Sun Xiurong had no need to recruit him, so Yu Wenjing killed Xi Riyue.

At the same time, the 100 people gathered around him with the essence of the Broken Leaf Army also killed all the elite warriors around Xi Riyue. Once these people died, the remaining soldiers surrendered without hesitation.

People born in the grassland admire the strong. Not long ago, Xi Riyue was still a real strong man. However, when a stronger man appeared, the Thunder Ye Army, which often affects the trend of the entire grassland, these "Tang Army" (or "Yan Army"?) dominated by Khitan and Xi people soon surrendered.

What's more, Sun Xiurong and the old chief Xi Nu were sworn brothers, so it was not difficult to surrender to him.

But it would not be so easy if Yu Wenjing met a general defending the city with Han people. This is a later story and will not be repeated.

In any case, Bogda Khan occupied Guizhou City!

Since Yu Wenjing entered the city from the west gate, he took the entire city and then let the army of the Sacred Ye army in the east enter the city for half a day, no one ran out to report to Li Guangbi. That's right, this army was still from Da Yan not long ago, and it didn't take long for the Tang army to surrender. On the surface, it still surrendered to the Sacred Ye army. For the rest, no matter who surrendered, it seemed that there was no big difference.

Li Guangbi was kept in the dark. Seeing that the Sail Ye Jun in the east for several days had not moved, he was happy to see this. His purpose was to trap Sail Ye Jun to death in the Guichuan River Basin. At the moment, Sail Ye Jun was unable to come, and he was eager to do so.

......

Three days passed in a flash.

Yunzhong County, Datong City.

As the northernmost place under the jurisdiction of the Hedong Jiedushi, the first snowfall came unexpectedly after autumn.

In the city, the prince and the governor Gao Xiuyan looked confused.

He never expected that he could get such a high status in his late seventies.

Just like Helou Yurun of Anxi, Lu Zhihui of Fan Yang, and Wang Xuanzhi of Andong, Gao Xiuyan was a standard Tang general with a certain background, but not prominent, and considered brave, but not outstanding, nor was he skillful, but he was also a master or above.

They were able to reach a high position at the end of their careers by chance.

Therefore, Gao Xiuyan is very satisfied with his current situation.

Yunzhong County is located between the Shanyu Governor's Office, Hedong and Hebei, and its geographical location is very important. After the renovation of the Northern Wei Dynasty, Sui and Tang Dynasties, Datong City is also one of the largest cities in the northern border. It is second only to Youzhou City in the same latitude and is still above Liucheng.

Otherwise, Gao Xiuyan could not accommodate 20,000 troops with the bitter, cold, barren, and cramped Yunzhong County.

Of course, in the past, the military rations of Yunzhong County were transported from Hedong. After surrendering to Dayan, they could only transport them from Guizhou. Specifically, it was a road from Guizhou City, Jingwende County, Tiancheng Army, Qing Pass Army to Yunzhong, which were all valleys between thousands of mountains and valleys.

Of course, there is a border wall to the north of Datong City, and there is also a Niupai Pass near Baideng Mountain. However, due to the great martial arts of the Tang Dynasty, the once powerful Turks had long disappeared. In the Tang Dynasty, the court's reliance on the border wall was far less than that of other dynasties, so it became disrepair.

As mentioned earlier, when Gao Xiuyan's eldest son took 10,000 elite soldiers to Guizhou east, he took that road. After 10,000 elite soldiers left, only 5,000 troops were left in Yunzhong County.

Five thousand men and horses also have protection including Datong City, Jingbian Army, Niupi Pass, and Wuzhou City, and the manpower is obviously not enough. Moreover, after An Lushan rebelled, Weizhou on the east side of Yunzhou was divided into two parts. The Qingsai Army north of the Sanggan River and Tiancheng Army became the territory of Yunzhou, while the Hengye Army, Lingqiu and Feihu were still under the jurisdiction of the Hedong Jiedu Mansion.

As a result, the military strength of Datong City became even more embarrassing.

The Weizhou that Li Guangbi promised to Xi Riyue was obviously only half of Weizhou, namely Hengye Army, Lingqiu, and Feihu.

After Li Guangbi personally led his army into the Guizhou Plain, his younger brother Li Guangjin stationed in Lingqiu (where Weizhou City is located) with 5,000 troops to protect his retreat.

Li Guangbi can make his brave and good at fighting as much as his own brother Li Guangjin personally guard Lingqiu, and obviously does not fully trust Gao Xiuyan in the north.

In fact, when Li Guangbi was in full force, the entire Hedong would be empty. At this time, if An Qingxu was braver, he would not only take over the entire Hedong, but at least he could take over Zezhou and Luzhou, which were close to Hebei to the south.

But An Qingxu was obviously not a visionary person. Seeing that the Tang Dynasty had "pardoned" him, he was always ready to play the role of the overlord of southern Hebei.

What he didn't expect was that Cui Qianyou and others, who were under him, would be willing to follow him to become local snakes?

It was once a terrible situation, so it was very suitable to put it here in Anqingxu.

I've been talking far and I've returned to Yunzhou.

On this day, Gao Mansion and even the whole city became lively, with only one reason.

Gao Xiuyan is about to celebrate his 70th birthday!

Gao Xiuyan spent most of his life fighting against the Tubo people on the Longyou Plateau. He worked hard without any credit. When he arrived at this grade, he was granted the title of Prince, which was naturally a major event for the Gao family. Although his eldest son Gao Lin was not around, the rest of the sects still worked hard for him.

Gao Xiuyan himself was also very relieved. Although he only had 5,000 troops and was still distributed in several places, the situation was almost the same as him around him. Moreover, as long as Datong City was present, the rest of the military forts would be lost. As long as Gao Lin returned to the army, it would be easy to capture the castles.

The two capable generals of Gao Xiuyan mentioned before, Tuoba Qianhui (the pioneer envoy and the Youyi envoy) from Tuoba tribe, and Tuoyuhun. However, Murong Fuyun (the marching Sima) who was a Jinshi of the Tang Dynasty, followed Gao Lin to Guizhou. In the current huge Datong City, except Gao Xiuyan and his children, is the chief of the Tuoba tribe, Tuoba Qimei.

In fact, there were only two thousand defenders in Datong City within a radius of twenty miles. If this news spread, the Zhenwu Army on one side would definitely have a different idea, but Gao Xiuyan had already transferred one thousand of Tuoba Qimei's tribal cavalry into the city, and with the young and strong people drawn in the city, he could barely gather up 5,000 people.

Gao Xiuyan had eight sons. After An Lushan's death, there was a great chaos in Hebei. Shi Siming, An Qingxu and Zhang Zhongzhi joined forces. The sons he left in Hebei naturally returned to Yunzhong.

The one who hosts his birthday is his eldest son Gao Song.

Originally, I wanted to wait until Gao Lin was in triumph, but today is Gao Xiuyan's 69th birthday. Chinese people like to celebrate their birthdays early, and people at this time are no exception. In the eyes of those who are mainly Gao Song, the Sail Ye Jun escorted 200,000 families northward, which was a bit rude. Even if the Tang army was not good, they could not defeat Sail Ye Jun, and they could still leave some Dingkou and wealth.

Li Guangbi persuaded Gao Xiuyan to use, "The bandits carried a million Dingkou to head north, and the soldiers were only 20,000 to 30,000. How could they take care of them? No matter how strong their combat power was, they could cover up half of Dingkou at most, and the remaining half would be divided equally. If the matter was successful, I would submit a report to the court and divide Shuozhou into the Datong Army."

This was naturally Li Guangbi's deception, just like he fooled Xi Riyue. In fact, from the perspective of the court, although Shuozhou is still outside Yanmen Pass, it is a place where military strategists must fight for. It is impossible to obtain any loss for a moment. How can one party decide its ownership?

But Gao Xiuyan was moved, for only one reason.

After Wu Zetian killed Cheng Wuting, Heichi Changzhi and other generals, the Tang army was once weak in the war with the Later Turks, and Yunzhong County became a battlefield for both sides. The farmers who farmed had long since ran to the inner gate (within Yanmen Pass). The Datong Army now relied on other places to import food and fodder. If 10,000 or 20,000 farmers could be moved, he, the Yunzhong Jiedushi, would be much more reliable.

The lights are on, and the birthday ceremony is officially staged!

"Report..."

In the world, eight out of ten things are unhappy, and it is also appropriate to put them here at Gao Xiuyan. When Gao Song was about to kneel down with his brothers and sisters and kowtow to Gao Xiuyan and present their own gifts, a disharmonious voice appeared in the courtyard outside.

This sound can appear in the backyard, obviously made by Gao Xiuyan's personal bodyguard.

Gao Xiuyan frowned. In fact, since Gao Lin took the army out, he pretended to be relaxed on the surface and used it as a birthday to realize that he was "well as Mount Tai", but in fact he was trembling and sweating.

But since things come to the door, I can't wince and be a turtle.

He waved his hand and asked everyone except his son Tuoba Qimei to retreat.

"Prince..."

The guard obviously wasn't willing to disturb the prince's gift at this time, but it was urgent and he had to come.

"Tell me, is it that news from Guizhou?"

"Reported to the prince, there has been news from the eldest prince. Everything is as usual. Now the Shattered Ye Army is surrounded by our army in the Guichuan River Basin and cannot move. Besides, Li Guangbi's army is in front of it. The eldest prince's army is still on the periphery. You can act according to the opportunity, so there is no major event."

"That......"

"Prince..., ahem"

"Say it, I'm sorry you are innocent"

"Yes, Prince, Niu Pi Pass Pass has been lost!"

Everyone was shocked when they heard this!

Niupi Pass, about twenty miles north of Datong City, is sandwiched between Baideng Mountain and Liuling Mountain. It is the only barrier to the north of Datong City. Although Gao Xiuyan is in a difficult military force, he also has 500 elite troops there. Because it is easy to defend and difficult to attack, it is very close to the city of the state. It is generally impossible to set off every day.

“Who is it…”

Gao Xiuyan's voice trembled.

"Prince, it looks like the Tang army. He is holding the banner of Shuofang Army. There is a word "Zhang" in it. It should be the left-wing military envoy under Guo Ziyi, the governor of Shuofang Army, and the Zhenwu Army envoy Zhang Yongji."

"Zhang Yongji?"

"The prince, most of the time, he used some of his military power to cross mountains and ridges to the south of Niupi Pass, pushed the grain cart to open and close the door, and then opened the North Close, causing the army to flock in. Because the incident suddenly happened, the defenders of Niupi Pass were taken down in a daze."

"ah......"

Gao Xiuyan screamed and suddenly fainted.

After a while, he finally woke up, "I inform the eldest son quickly and ask him to return to the army to rescue him!"

This is Tuoba Qimei, but said: "Is it inappropriate for the prince to hurry up and let the eldest prince return to the army before he had figured out the truth? Although Zhang Yongji was a powerful general, he was not a good person to use tricks. Niu Piguan was built in the Han Dynasty. After many dynasties, they were all properly repaired. The elite guarding the Guancheng was also the elite of Yunzhong County. Why did he go down in one go?"

Gao Xiuyan shook his head, "Zhang Yongji has people who are all from Shuofang Army who know the military commander Pugu Huaien. Pugu Huaien has many Hu people who are familiar with Datong. It is no problem to cross mountains and ridges. In the late Tianbao period, Pugu Huaien was the Datong Army envoy. He was not only familiar with Niupi Pass, but also with the soldiers there, and was also quite kind. Most of them promised the guards such a way."
