Shanhaiguan, the majestic pass between mountains and seas, controls the southern entrance of the western Liaoning Corridor.?

This is also the most important strategic defensive pass between the Ming Dynasty and the Tartars outside the pass and the later Qing thrones. However, in fact, the road to western Liaoning is not the only way to go out of Shanhaiguan and the Liaoxi Corridor.

In fact, in the more ancient times, during the Spring and Autumn Period and the Warring States Period, there were many small countries in Yan. Later, Yan State connected with Youji, becoming one of the seven heroes of the Warring States Period. Yan State was based in the northeast, not only competed for power with Zhao and Jin, but also actively expanded its territory to the north. The Yan Great Wall also enclosed the vast area north of Yanshan Mountain and a large area of ​​land in western Liaohe that reached the east to the Liaohe River into the Yan Great Wall, which was further north than the Ming Great Wall.

At that time, the coastal areas of the western Liaoning Corridor were mostly below sea level, and many roads were flooded every summer. The western Liaoning Corridor was more in the Daling River Valley than in the coastal line today.

The Yan State has a wider territory in northern Yan, and they are not satisfied with relying solely on the western Liaoning Corridor.

Before the Liaoxi Corridor, there are actually three ancient Liaoxi roads. These three ancient roads are Pinggang Road passing through the ancient north entrance of Miyun, Lulong Road passing through Xifengkou, and Wuzhong Road traveling north along the Qinglong River Valley.

These three roads start from three different southern entrances, all cross the Yanshan Mountains, and then cross the Luan River until further north.

Zunhua area was a small country called Wuzhong during the Spring and Autumn Period. The capital Wuzhong City was in today's Ji County. After the Yan people controlled this area, Wuzhong City became the newly established Youbeiping County and County District of Yan State.

Next to Youbeiping County is Yuyang County, and Yuyang is named because it is south of the fishing water. The so-called fishing water is the Baihe River in Chaobai River.

The southern entrance of Wuzhongdao is controlled by Wuzhong City, so the starting point of this ancient Liaoxi Road, located in the east, is named Wuzhongdao.

After the extremely large amount of water comes down from Yanshan Mountain, the Luan River runs through the entire area and flows south into the sea. Along the river valley, it becomes a natural road that passes through the Yanshan Mountains.

"This place was once Guzhu Kingdom in the Spring and Autumn Period. Like Wuzhong Kingdom, it was once a viscount and vassal state of Zhou Kingdom. Like Chu Kingdom, it was not an indigenous tribe of the Chinese clan. It was named a prince and was eventually annexed by Yan Kingdom, which made it famous as one of the seven heroes of the Warring States Period."

The army walked along the Luan River and walked along this ancient road without end.

Liu Jun listened to the guide's detailed introduction to the history of this place. This is a place with a long history. In fact, the history of Chinese civilization is also a history of conquest. On the land of the Central Plains, countless tribes lived. The tribal war between the Yan Emperor tribe and the Huang Emperor tribe, and later they joined forces to fight with Chiyou's tribe.

In short, the tribes continued to fight, annex and merge, and finally by the Qin State, the world was basically unified. Ches and the same books and writings truly formed the Huaxia Empire. The hundreds of years of continuation of the Han Empire made them more deeply integrated and the Han people.

Countless surrounding tribes were conquered and assimilated, and then they became the Chinese clan and the Han clan.

Now, except for the Qing Dynasty in the northeast outside the pass, Mongolia in the northern grassland, Korea on the Korean Peninsula, natives in Yunnan and Guizhou in Guangxi, Miao people, people from Qinghai in Gansu, Tibetans in Wusizang, etc., the vast world, basically all over the world, are basically covered with Chinese civilization. The Han people are everywhere.

During the Spring and Autumn Period, Yan State represented a member of the Chinese tribe, constantly exploring the northern border. Together with the Zhao State in the west, most of the Mongolian grasslands in the south of the desert were included in part of China.

Unfortunately, the climate of the grassland is not suitable for farming. Although the Central Plains agricultural civilization once controlled the southern desert area, it was unable to occupy it for a long time.

At the beginning of the founding of the Ming Dynasty, it had reached the Beihai several times, but now, the northern border has retreated to the line of the Yanshan Mountains. The northern foothills of the Yanshan Mountains have long been occupied by the Mongolian tribes, and the Mongols were conquered by the Qing people. Now this place is the territory of the Qing people.

Think about the Western Regions Protectorate during the Han and Tang Dynasties, the four counties of Liaodong in the Han Dynasty, and the Andong Protectorate during the Tang Dynasty.

When the Han people were the strongest, they reached the Tianshan Mountains in the west, North Korea in the east, and Lake Baikal in the north. Then, today, the northern border is only reliant on the Yanshan Mountains, and the capital of the empire is only three hundred miles away from the border.

Liu Jun looked into the distance from the horse and saw that the vast rivers and mountains of Yanbei could not become the shield of the empire, but instead became the base for the enemy's invasion.

"Remember my words."

The historian who accompanied him rushed forward and quickly turned the page and picked up the pen.

"North of Yanshan Mountain, Luanhe, Chaohe, Qinglonghe and Tuhe River basins, it was established as Yanbei Province, the 23rd province of the Han Empire, and the provincial capital Chengde."

As long as Liu Jun did not plan to move the capital and succeeded to Beijing, the Yanbei region would have to be controlled no matter what. Without the Yanbei region and relying on the defense of only one Yanshan Mountains, the strategic defense depth of the capital would be too weak. With just one defense, a distance of hundreds of miles, the enemy outside the pass could break into the capital at any time.

The Ming Dynasty was established for more than 200 years ago. Before, the Emperor of Ming Dynasty was captured by the thorns, and the army was at the city of Beijing. Later, the Qing army bypassed Shanhaiguan and again came to the city of Beijing.

All of this is because the capital lacks defense depth.

The so-called emperor guarding the country's gates is indeed very encouraging in one aspect. But on the other hand, this is a very dangerous arrangement, especially when the capital is established, the enemies in the north are often fierce nomadic peoples or fishing, hunting and farming peoples, and their military strength is often quite strong.

The thin layer of defense in Beijing is undoubtedly always attracting the enemy to go south. Once the official army has a hole in the defense layer on the Yanshan line, the entire defense network will lose its effect and cannot be remedied, and the capital will be immediately exposed to the enemy.

Although the demise of the Ming Dynasty in history was diverse, it must be related to the poor defense situation in Beijing.

Even the Yan Kingdom in the Spring and Autumn Period knew that in order to gain a foothold in the north, it was necessary to build the Yan Great Wall thousands of miles north of Yandu.

Zhang Guodong, the admiral behind Liu Jun, did not know that the emperor was thinking so long. He smiled and said, "The golden family had long declined back then, especially the Mongolian tribes in the south of the desert. Lin Danhan still wanted to cheer up and reunify the tribes, but unfortunately he was colluded with the Manchus and the Manchus and fled west. Since then, the tribes in the south of the desert have surrendered to the Manchus. Now the Mongolian tribes in the south of the desert have set up alliances to draw flags, and one by one is in front of the prince Taiji, and they are very uncomfortable and carefree to serve the Manchus."

"But this time their master will lose his own protection. In the future, the Manchus will not be able to get involved in the southern part of the desert. Your Majesty wants to establish Yanbei Province, even if it is established, Monan Province and Mobei Province are not a problem. When we have time, we will have time, please allow your Majesty to lead troops to Liaodong, and then continue to Jianzhou and Heilongjiang."

Liu Jun smiled, "What's the point of hitting Heilongjiang? Then you will still hit Chuyuerhai."

"You have no jokes. Your Majesty has agreed to the last general today. At that time, I will definitely let me lead my troops to recover Liaodong."

"Hahaha, you don't joke. If you really hit Chuyuerhai in the future, I will give you the title of Governor of Mobei."

A fast horse arrived.

The knight was dismounted from the horse, and the guards confirmed his identity and took him to the front of the carriage.

"Your Majesty, twenty miles ahead is Chengde."

"Have you arrived in Chengde? Tell me how many Qing troops stayed in Chengde?"

"Your Majesty, there are less than 5,000 soldiers and horses left in the old camp of the Qing army in Chengde, who are specifically responsible for collecting cattle, sheep, food and grass from nearby Mongolian alliance tribes and transferring them to Chaohe Front."

Liu Jun asked again, "Can the Tartars show our whereabouts?"

"The Tartars were unaware of it. There are only more than a thousand people in the camp now, and the rest have gone out to collect grain."

"Very good." Liu Jun nodded, "Zhang Guodong."

"I'm here."

"I ordered you to be the vanguard and lead a vanguard from the association to capture the old camp of the Qing army for me."

"I accept the order!" Zhang Guodong responded happily.

Liu Jun specifically explained, "If you meet the Mongols of Kalaqin Banner, you don't have to be polite to them. If they are willing to abandon the darkness and turn to the light, we can go on the past, but if they are obsessed with and want to go to the darkness with the Tartars, then destroy them."

The Luanhe River is all from Kalaqin Banner. The Kalaqin tribe has three banners, which are affiliated to the Zhuosoutu League.

Liu Jun had no good attitude towards these Mongolians in the south of the desert who surrendered to the Qing Dynasty. In the first two hundred years of the Ming Dynasty, he almost always opposed the Ming Dynasty and robbed the border. Later, he reached a peace agreement with the Ming Dynasty and traded with each other, but he did not violate the rivers. When the Jurchens first rose, he also followed the Ming Dynasty to work with the Jurchens, snatched their women, killed their children, and burned their houses.

But later, the Jurchens came and they were afraid that they could not defeat them. They knelt on the ground and sang to conquer them. From then on, they were determined to follow the Qing Dynasty to fight the Ming Dynasty.

"Please rest assured that I will fulfill my mission. This will make them look good, whether it is the Manchu wild boar skin or the Mongolian slutty tatars."

"After taking Chengde, don't go in easily, wait for me to lead most of the people over. This time, we want to net big fish, so don't alert me."

Chaohe Qing army camp.

Haoge had already ordered Zheng Lanqi's subordinates to pack up their luggage and prepare to retreat.

Duoduo still refused to retreat, and he did not allow Wu Sangui and Zu Dashou to retreat. In the camp, Duoduo was drinking wine, and his brother Ajige sat aside, "Haoge is really going to retreat, why do you still have the heart to drink? He holds 50,000 troops in his hand. If he leaves, our strength will be greatly reduced."

"It's raining and my mother is going to get married, and he Haoge is leaving, how can I stop me?"

Ajige's fist hit the table, "This dog-good Haoge, he was deliberately dismantling our station at this time. Brother, why don't we withdraw too? Liu Jiye has not made any noise yet, and I always feel uneasy. Could this bastard have already taken our way of retreat or fought against Liaodong?"

Duoduo shook his head, "Impossible, I have spies in the pass. These days I have received secret reports from the pass every day. The troops stationed in Guanning and Yanbei Great Wall have not been mobilized in a town. There are no soldiers and horses in the capital area of ​​the pass. Liu Jiye is still pretending to us. Now it depends on who can't calm down or who can't calm down, and he loses his momentum and can only give in. I want to fight Liu Jiye to the end, but I want to see how long he can last!"
