Xiaoguan is located in Guyuan County, Ningxia today. The Liupanshan Mountains lie across the northwest of Guanzhong and serve as its northwest barrier. The main passage from Longshan to Guanzhong is the Wei River, Jing River and other rivers cut through to form a valley lowland. Several huge canyons crossing Liupanshan, which has become the main business road to the west to the Silk Road, and it is also a convenient way for northern nomads to enter Guanzhong.

Since the Qin Dynasty, the Central Plains Dynasty built the Great Wall along Liupan Mountain for defense, and the famous Xiaoguan was also formed.

Xiao Pass is not a pass, but refers to the Great Wall defense system about twenty miles long from Muxia Pass to Liupan Pass. It is actually three points and one line.

At one point to the south is Liupan Pass, which consists of three passes, including Wujin Mountain, Xiandi Mountain and Longdongyuan. The Guanbao Fortress was built, and beacon towers were built at high places.

The middle point is Wating Gorge, which is also a huge canyon that runs across Liupan Mountain. The Qin Dynasty relied on the mountain to build a solid pass here, called Wating Gorge.

Muxia Pass is one point north, and Gaoping County is outside the pass, which is also a place where Wuhuan troops are concentrated. These three passes are collectively called Xiaoguan, also known as Sanguankou.

Compared with the rugged and steep Jieting to the south, Xiaoguan Valley Road is flattering and more convenient for caravans, cavalry and other animal forces. Therefore, Xiaoguan Road has become two important roads as famous as Longguan Road since ancient times.

Over the past decades, the Mihu continued to invade the south, and Xiaoguandao gradually fell into the hands of the Hu people and was successively controlled by nomadic peoples such as the Huns and Wuhuan. At present, Xiaoguandao was controlled by the Anding Wuhuan people.

Xiao Guandao was like a button of a piece of clothing, closely linking the two lapels of Longxi and Guan's inner clothes. It is precisely for this reason that regaining Xiao Guan became the first step for the Han army to launch the Guanshuo Battle.

However, over the past few decades, the sphere of influence of Han and Hu have gradually stabilized. North of Xiaoguan belongs to the Miscellaneous Hu forces, and south of Xiaoguan is the Central Plains dynasty. This division of spheres of influence has become a tacit understanding between the two sides and is recognized by both sides. To break this tacit understanding, we must patiently wait for the opportunity to appear.

At this moment, the Wuhuan people in Anding crossed the border to harass the residents of Guanzhong, killing people and plundering money, and were fierce and cruel, which gave the Han army an excellent excuse to send troops.

Outside the Wating Canyon are rolling hilly slopes, and the mountains are gradually rising to the east. A strong Great Wall pass was built at the dangerous terrain at the entrance of the canyon. It is easy to defend but difficult to attack. In addition, a military city was built based on the mountain. The military city was two miles long and one mile wide. The city was two feet tall and seven feet high. The city wall was one feet thick and three feet thick, and the bottom was two feet thick. The enemy tower was erected, with dense marches, eight piers and seven sinks, standing as a majestic town. This is the famous Wating City.

Wating City was built during the Spring and Autumn Period and the Warring States Period. It was originally intended to defend against Wurong, so it was also called Wushi County. Later, Wushi County moved eastward, Wating City became a pure military city. It is currently controlled by the Wuhuan people. There are 500 troops stationed in the city, and a thousand soldiers on the Great Wall formed a very strict defense system.

Since Wuhuan chief Bian Shu felt that the Han army was going north, the Wuhuan army, led by Chining, stationed 7,000 heavy troops on the Xiaoguan line to defend the Han army from heading north.

That night, the wind was dark and the moon was covered with dark clouds. The five fingers were missing. An army marched rapidly in the mountain road canyon and headed towards Wating Pass several miles away.

This Han army was about 8,500 people, all of which were Liu Jing's direct troops. Among them, Wang Ping led 3,000 barbarian soldiers, Liu Zheng led 500 Eagle Strike Army, and Ma Dai led 5,000 cavalry. Their mission was to capture Wating Pass and Wating City outside the Pass, and detour northward to intercept the Wuhuan Army.

Liu Zheng and deputy general Ren Ping led the 500 Eagle Strike Army to advance first. Since capturing Guanzhong, the Eagle Strike Army has been in a state of rest. Although Liu Zheng was unwilling to calm down and pulled the 500 Eagle Strike Army to the West Sea Plateau for nearly a year, there was no military operation for a year, and almost caused Liu Zheng to get sick. Tonight, the Eagle Strike Army finally received the first mission in a year. Liu Zheng was ecstatic and led the 500 elite troops to Wating Pass.

The task of the Eagle Strike Army was to capture Wating Pass and Wating City. The subsequent battle was handed over to the barbarians and cavalry. After crossing a ridge, countless highlights appeared in front of them, and a long line was lined up in the low night sky, which was the Great Wall. The highlight was the torch lit by the Wuhuan people, and the place where the flames gathered was the Wating Pass City Tower.

Wating Pass is actually part of the Great Wall. The city wall is two meters high. Outside the pass is a huge slope that slowly descends, with a drop of dozens of meters below the slope. The terrain is very dangerous. From the pass inside, it is basically level with the city wall. You only need to climb the Great Wall that is two meters high to seize the pass.

But soon, the Eagle Strike Army discovered that things were not that simple. A scout rushed over and reported to Liu Zheng: "Report to General, the situation of the pass has been found out."

Liu Zheng immediately ordered: "Make a account!"

Several soldiers quickly set up a double-layer marching tent behind the ridge, with four corners covered tightly. The inner tent was lit with candles, and the light did not leak out. A military blanket was laid on the inner tent, and a wooden model with a pass-like appearance was placed on it. There was a wall on each side, almost exactly like a tile pavilion.

Liu Zheng and Ren Ping sat cross-legged on both sides of the carpet and listened to the scout's report. The scout pointed to the model and said, "Although the city wall is not high, a large number of enemy troops gathered on the city. If you climb up the city, you will inevitably fight fiercely with the enemy. The enemy has obvious advantages and we will suffer heavy losses."

Liu Zheng pondered for a moment and asked again: "What if he went up from the city walls on both sides?"

"Although there are not many soldiers on the walls on both sides, they are built on the mountain. The mountain is very steep and steep, and the stones are very smooth and difficult to climb."

"How wide is the city wall?" Ren Ping suddenly asked.

"About two to three feet."

Liu Zheng nodded and said to the scout: "You retreat first!"

The scout retreated, with only Liu Zheng and Ren Ping in the inner tent. Liu Zheng sighed and said, "The key is that we did not carry a siege ladder. We were surrounded by bare stones and trees. We could only climb the city by ropes. But once discovered, the ropes were easily cut."

Speaking of this, Liu Zheng looked at Ren Ping again and asked tentatively: "What do you think?"

"If you don't leave Guancheng, go up from the walls on both sides!"

Ren Ping's attitude was very clear and said, "Although the mountains on both sides are steep, they are really nothing to our Eagle Strike Army. The more important thing is that there is a foothold above. As long as we have a foothold, we can easily get to the city."

Liu Zheng pondered for a moment and decided resolutely: "Go up from the walls on both sides!"
