After the Tang army converged in Guangchang County, the front of the troops was suspended, because if they fought further south, the situation they faced would be different. Guangchang County is located at the intersection of Puyin and Feihu, so it can be said that this is a crossroads. Whether it is along the Flying Fox to the north to Dai County and other places, or to the south to Zhongshan, Changshan and other places, you have to pass through here.

In the same way, whether it is along Puyin to the east into Fanyangguo, Yanjun and other places, or west to Lingqiu, into Yanmen Pass and other places, it must also pass through here.

In this way, the county seat of Guangchang has become a place that extends in all directions, mastering the main roads in all directions.

To put it bluntly, this place became a springboard that could become a base for the Tang army to go out in the future.

Fortunately, Guangchang County is located in the basin, surrounded by the Taihang Mountains. Otherwise, such a place is destined to become a place of constant war, and with the mountains guarding it, it will become an easy place to defend and difficult to attack.

If it weren't for Murong Ping's incompetence, it would not be an easy task to really rely on hard fighting to take down this place. After all, the Yan troops in the south and east will inevitably rush to support in large numbers after hearing the news of the attack here.

It can only be said that Murong Ping did a good deed this time and gave Tang Jun a big gift. Taking the county seat of Guangchang means that the Tang army has taken another big step forward, and it is already the place that has begun to threaten the heartland of the Yan Kingdom.

"The importance of Guangchang County, there is no need for this king to say more! Now that this place has fallen into our hands, we must not allow it to be lost again! However, at this point in the war, there is nothing to fight here. Next, it's time to change the target! In the county government, Li Xin held a meeting again.

"Your Highness, now that Murong Ping has fled in embarrassment, I'm afraid that the Yan army in Zhongshan, Changshan and other places has already known the news of their defeat. There are still Changshan Pass in the south and Wuruan Pass in the east, which are still in the hands of the Yan army. Why don't we take it away while it's unprepared? In this way, even if the Yan army counterattacks in the future, it will not be able to threaten Guangchang County! It is said that it is Daijun Yanmen and other places! Liao Chuan suggested.

"That's what this king wants! Now those two passes, when Murong Ping fled, he went east. In this way, Wuruan Pass should know the news first. Yao Chang, you lead 3,000 soldiers and horses, immediately go south to take Changshan Pass, and then stay there first to guard against the enemy! Shi Yue, you also led 3,000 soldiers and horses to take the Wuruan Pass, and then left behind to defend the town. As for the rest, this king has his own schedule! Li Xin nodded, and then nodded generally!

Shi Yue was originally a general of Fu Qin, and later when Fu Qin was destroyed, he also followed the Huashan army. Over the years, he started as a small soldier, and because of his military exploits, he was eventually promoted to the position of general, and he was among them in this dispatch.

"Your Highness, rest assured, the last general will definitely complete the military order!" Yao Chang and Shi Yue hurriedly stood up and responded.

"Guangchang County is an important place, and the impact between gains and losses is significant, and there is no room for loss! Immediately transfer Shao Zisong to come here to guard! As for Liao Chuan, you will return to the bank of Luoshui with this king, and go east to Guangning Shanggu and other places, and be sure to take these two counties as soon as possible, and the general will be in your hands! At the end, Li Xin ordered everyone again.

"The last general obeys!" Everyone bowed in unison.

If you go northeast along Luoshui from Daijun, you will arrive at Huailai, Zhangjiakou and other places in the future.

This place was under the jurisdiction of Guangning County and Shanggu County at this time, and the land of Zhangjiakou was not called this name at this time. In addition, the region was divided between Quang Ninh County and Sang Gu County.

The land of Guangning County originally belonged to Shanggu County, but during the time of Emperor Wu of the Western Jin Dynasty, Shanggu County of Youzhou was divided into a part to set up Guangning County. Its seat of governance is in Xialuo County, that is, the west side of Zhuolu County in later generations.

However, with the fall and chaos of the north, the territory of Quang Ninh County became smaller and smaller, and now, there are only three counties left. They are Xialuo County, as well as Pan County to the south and Zhuolu County to the southeast.

The history of the establishment of Shanggu County is very long, and the earliest time can be traced back to the time of King Yan Zhao during the Warring States period. After he defeated Donghu, he set up five counties in the north: Shanggu, Yuyang, Liaodong, Liaoxi, and Youbeiping.

Later, Qin Shi Huang unified the world and set up 36 counties, and Shanggu County was also one of them. The Han Dynasty inherited this setting from the Qin Dynasty, and even after the great chaos in the world, after the Three Kingdoms, the Wuhu Rebellion, etc., basically the governance of Shanggu County did not change much.

Today's Shanggu County, there are only two counties left, namely the county of Fuyang County, and the east of Juyong County. Among them, Fuyang County is located in the southeast of Huailai County in the later generations, while Juyong County is located in the east of Yanqing in the later generations.

The two counties of Shanggu and Guangning are bordered by Yanshan Barrier Desert in the north, the army in the south overlooks the Central Plains, and there is Xiaowutai Mountain in the west and Dai County is adjacent to it. In the past, this place was still the starting point of the Yan Great Wall, controlling the entry and exit of the Juyongguan Great Wall.

Although it is divided into two counties, there is not much difference between Quang Ninh and Sang Gu counties when they are connected. These two counties blocked the military capital of the North China Plain over the Taihang Mountains and into the Datong Basin and the Loess Plateau in the west.

Since ancient times, the Central Plains Dynasty went out of Saiweibian, and expeditions to the desert often entered Shanggu County from the military capital, and then crossed the Yanshan Mountains from the northern side of Zhangjiakou to reach the outside of Saiwai. When the brilliant Emperor Wu of the Han Dynasty defeated the Xiongnu, this was one of the main routes to go out.

From this, we can see the importance of these two counties, and if anyone masters this place, they can go straight into the desert grassland. If you retreat, you can enter the Central Plains such as Jicheng in Yanjun County through the military capital, and if you go west, you can enter Taiyuan Shuofang and other places, and then threaten Guanzhong.

Basically, the importance of the two places in Shanggu and Guangning is still above the county seat of Guangchang. If you can't take down this place, then, even if you get all the places in Dai County and Yanmen County, you have to always worry that the Yan army will kill to the north of Flying Fox through the military capital.

In that case, the value of places such as Guangchang County will be greatly reduced. The important thing is that for the Tang army stationed in Daijun and other places, the threat is too great, and it is very difficult to defend it thoroughly.

The general strategy of marching into the army was already considered at the beginning. This is one of Li Xin's habits, before every big war, he has to plan in advance to see which places must be taken down and which places can be abandoned.

Of course, if you can win them all, it will be the best. But there is no such thing as perfection, so sometimes you have to give up!

This alliance with Huan Wen was actually an idea he came up with on a whim to a large extent. Because for places such as Kamitani Daigun, he has actually been salivating for a long time, but he has never found a good entry point.

It just so happened that Huan Wen sent troops to the south and was able to share the pressure on himself in the north. In this way, you will be able to achieve your goals and achieve your long-standing strategic intentions.

Ordinary people may not be able to see it, but for a master like Wang Meng, it has long been seen that he seems to be playing ordinary chess. Although Wang Meng also asked tentatively in the past, Li Xin always smiled and did not speak.

The overall situation is there, and when everything is in order, everyone in the world will understand. Whether it was to win Shuofang before, or to send troops to take Daijun and other places this time, it was actually just one step in this big game of chess.

After the arrangements were made, Li Xin led the army back again. Since the various parts of Dai County have basically been pacified, this time Li Xin mobilized a group of town troops from Yanmen, Taiyuan and other places.

In addition to important places such as Changshan Pass, Lingqiu Pass, and Feihukou, which are still guarded by the regular army, the remaining Daixian, Mayi and other places will be handed over to the town army to be responsible.

In this way, when he led his army to Quang Ninh and Shanggu to kill again, he would have more than 20,000 troops in his hands.

Although such a force may not seem like much, Li Xin did not want to mobilize a large army from the rear. After all, there are not many regular troops in the Huashan Army today. Moreover, the soldiers are not much more expensive, wasn't Murong Ping a good example before.

There are not many roads from Dai County to Shanggu and Quang Ninh, after all, this is at the junction of Taihang Mountain and Yanshan Mountain Range, full of cliffs and dangerous peaks, and various geological conditions are extremely poor.

The most suitable way is to cross the river from the confluence of Luoshui and Qiyishui, and then head northeast. The road is relatively open and flatter, making it suitable for large armies. But the problem is that even the dullest enemy in such a place will inevitably step up its precautions.

Also, if you get from here, you'll have to take a detour, which is a much longer distance.

The second way is to go directly east along Luoshui and go through the mountains and valleys. This road is high and dense because it runs through the mountains. If there are not a guide and there are not many of them, it is very dangerous.

However, the straight-line distance of this road is the shortest, and it can be directly from the place where the former Sangkan county seat of Dai County is located to the city of Luo County, which is under the rule of Quang Ninh County.

The third way is from the northeast of Dangcheng County, all the way over the mountains and rivers. The distance of this road is not too long, and, compared to the second road, it should be relatively better.

After getting out of this road, it is the border of Zhuolu County, and you can kill all the way to the county seat of Shanggu County.

"This time, after our victory, we will take the opportunity to forge ahead, take the city as the second, and destroy the enemy as the most important! Therefore, it was necessary to arrive at the predetermined destination before the enemy reinforcements from Yanjun and other places arrived. Therefore, I am afraid that the ordinary method of marching into the army will not work, we must act separately! On the way to the army, Li Xin said to the generals.
