Not a hero if you are not a great wall.

Climbing the Great Wall and following the steps one by one, you will stand at the highest point. From a high place, the south is Mayi, and to the north is the south of the desert outside the border.

"The solemn autumn wind blows, traveling thousands of miles.

Where can I go thousands of miles? Build the Great Wall in the desert..."

Luo Cheng stood on the Great Wall, stroked the battlements of the Great Wall with his hands, and couldn't help but recite a poem. This is a Yuefu poem called Yinma Great Wall Cave Walk, which was first written in the Han Dynasty.

However, Yang Guang, the emperor of this dynasty, also wrote a poem about drinking horses and drinking the Great Wall Cave, which was the poem by Luo Chengyin. It was very domineering. People at that time praised him as Wei Wu and could be compared with Cao Cao. Not only did Cao Cao command troops and govern the country, but his poems were also amazing. Yang Guang's poems were indeed great to compare with Cao Cao.

"Master, are you sure you will pass from now on?" Changsun Wuji asked.

Because this kid sneaked into Khan City alone to persuade Princess Yicheng to surrender in the city, he was appointed as the captain by Luo Cheng making an exception and even arranged him to be in the White Horse Yicong.

"This mouth is called the sanhekou, which is the only mouth for the sanhedao. The sanhedao is also the only place for the three roads of Mayi, Dingxiang. In the past, Bi went south and walked here, but now he was going back, so he would still walk here. So as long as we stay here, we can wait for the rabbit."

Shenhekou, also known as Bailang Pass in the Tang Dynasty, was called Xikou in the Ming Dynasty, or Kill Hukou and Hukou. It is very famous and is the only way to Datong to Hohehotte.

Even in later generations, the important highway from Datong to Hohhot is also this route.

There is a continuous outer Great Wall here, and the Ganhekou is an important natural barrier.

It is adjacent to Tangzi Mountain in the east, Dabao Mountain in the west, Leigong Mountain in the north, Miaotou Mountain, and the Great Wall extends from northeast to southwest, like a semicircular wall surrounding the tiger's mouth.

The cliffs on both sides of the east and west are steep, and the Zi River runs through it from south to north, forming a natural pass that is only more than 200 meters wide and more than 3,000 meters long.

The open Zihe Valley between the two mountains has been an important passage between the north and the south since ancient times.

Shenhekou was once an important Great Wall pass. After the founding of the Sui Dynasty, the focus was on defending the inner Great Wall on the Yanmen line, which was also the Senei surround of the Northern Wei Dynasty.

The control of the outer Great Wall was actually not strong. The court only established Mayi County outside Yanmen. There were some cities and villages close to the inner Great Wall. In addition, there were only some small forts on the outer Great Wall line, and occasionally border soldiers were patrolling.

More than ten years after the return of the Khan of Qimin returned to the Sui Dynasty, there was no war in the south of the desert, and the Sui Dynasty suddenly stabilized, so the outer line of the Great Wall became even more relaxed.

Shibi Khan went south and crossed the dangerous gankou without any obstacles.

"The Great Wall outside is already very broken."

Luo Cheng sighed a little, grass grew on the Great Wall, and some places even collapsed.

After the Sui Dynasty unified the world, the northern overlord Turks was soon infighting with Yang Jian's strategy of separation, strength and weakness. Several times, the Sui Dynasty jointly suppressed the other, and later it was even more difficult to suppress the Sui Dynasty.

With such an advantage, the Great Wall of the Sui Dynasty was not repaired on a large scale.

That is, after Yang Guang ascended the throne, he made a major repair. That time he started from Yulin County in the west and went to the northwest of Mayi. He just happened to be near Shenhekou and there was no repair.

"This place is only 240 miles away from the Khan Court in Monan, only 220 miles away from Mayi City, and only 170 miles away from Yunnei in the east. It can also connect to Youyan and Hetao, and the military strategists are in need."

The Great Wall of Shenhekou is made of earth and is not covered with bricks. It looks gray and broken, but it can still be seen that the danger of this Guancheng.

At this time, countless people were strengthening the gate of the Ganhekou.

The city of Shenhekou Pass is rapidly changing its appearance. The city is surrounded by two miles, and the Zhongwu Army has already entered the city of four meters high.

Moreover, inside and outside the Guancheng, Luo Cheng also sent people to repair, reinforce and expand several fortresses. Although the size is not as big as this Guancheng, walls are built between the several fortresses, forming a horn to support each other.

If you are tall on the high city, you can actually take a look at the terrain here.

There are different sizes of Daibei Basins in the north and south, and this is the river valley between the continuous mountains, and the narrowest and most dangerous intersection connecting the basins.

To the northeast of Guancheng is the Liangcheng Basin and the Chanhebei Lake. There are now 60,000 Turkic troops stationed there.

However, these Turkic tribes were led by Asunasmo and Princess Yicheng, and were obeyed by Luo Cheng.

Luo Cheng never planned to go to Yanmen.

He did not plan to fight Shibi in Khan City. After all, Khan City was built on the grasslands in the south of the desert and had no danger to defend.

Luo Cheng already knew that Shibi Khan did not gain much advantage when he went south.

Although he had captured more than 40 cities in Yanmen, Yanmen was unable to capture. The emperor and the officials did not get a disaster, and he also lost more than 100,000 troops.

Although this trip south also robbed many people, Luo Cheng thought that it was a loss at first.

After all, Yanmen and Mayi are both border counties, and the population is not large. At first, they destroyed more than 40 cities and did not grab a total of 200,000 people. As for how much money can be, livestock and food were even eaten by his army.

He lost 120,000 troops, defeated more than 40 cities of Sui Dynasty, killed about 100,000 troops, and robbed less than 200,000 people. This is a loss-making deal.

What's more, Luo Cheng also confiscated his Khanate, killed more than 10,000 Duo's troops in the south of the desert, and surrendered him 60,000.

But Luo Cheng is not so easy to satisfy.

Shibi retreated from Yanmen, but it was not that easy to return to the grassland.

"As I just received, Your Majesty has appointed General Siye as the governor of Dingxiangdao, and ordered the governor of Mayi Wang Rengong and the governor of Monandao to send troops to cooperate with General Siye's pursuit of Shibi."

"The emperor also issued an order to control the troops in the four towns."

"Where is the emperor?" Luo Cheng asked.

The scar on the purple-faced Heavenly King Zhao Gui's face was purple and purple. Anyone who knows him knows that this is a sign of his unhappiness.

"As soon as Yanmen cleared the siege, the emperor immediately went to the Jinyang Palace in Taiyuan, and took away all officials and the army of the king. General Siye asked for pursuit, but the emperor refused. General Siye resisted the order and led the remaining 8,000 troops of the left army to the north. Then the emperor issued an order to grant him the title of the governor of Dingxiangdao."
