Luguan is located in the valley, where the mountain is high and steep, like a gourd, so it gets its name. This place controls the Hetao in the north and Yan'an in the south, and has been a border fortress for soldiers since ancient times. Historically, many poets have written poems to praise this pass, and the great poet Du Fu is one of them. Speaking of which, Li Xin is relatively lucky. Because today's northern Hu people are a mass of scattered sand, not as strong as the Xiongnu in the Qin and Han dynasties. Otherwise, it would be absolutely impossible for this land of Luguan to be taken by Shao Zisong so easily.

Although today's Luguan is already in disrepair, it is still very strong today because the predecessors invested a lot of manpower and material resources to build it. Coupled with the danger of the terrain, it has not been damaged too much.

Standing on the wall of Luguan, Li Xin looked around and saw a world of ice and snow in front of him. Seeing this scene, Li Xin couldn't help but say to himself: "This is really a northern scenery!" It's thousands of miles of ice, thousands of miles of snow drifting! ”

Everything is withering, all under the snow, a white world in front of you, everything seems so pure and pure! However, by next year, it will all be green.

Outside of Luguan and further north, dozens of miles away is where the grassland Gobi is located, where the Hu people really live. It is precisely because of the proximity to this place that whenever the Hu people from the north invade the south, Luguan becomes the first place to bear the brunt.

In addition to Luguan, the other most convenient place is Xiao Pass in Beidi County. It is about the same latitude as Luguan, and the two can be said to be one east and one west, jointly defending the north gate key in the pass! Naturally, its importance is needless to say.

"Luguan! Here, how many people have died on the battlefield, and the yellow sand is stained with blood! Did you know that before Qin unified the Six Kingdoms, this was once the land of Yiqu? After watching silently for a while, Li Xin spoke.

"The last general doesn't know, he only knows that this place has been an important place since ancient times, and the soldiers will fight for it!" Shao Zisong was stunned for a moment, and replied a little ashamedly.

"It's not surprising that you don't know, after all, when Yiqu controlled this place, the time was not very long, and soon this place was owned by Qin! This is nothing, the important thing is that later, after Qin Shi Huang unified the six countries, he sent Meng Tian to lead 300,000 troops and garrison them in this area, in order to guard against the Hu people! Hearing this, Li Xin couldn't help but smile and continued.

"This, Meng Tianmo will know! I have heard of this person, he is a famous general in the Qin Dynasty! He defeated the Huns, so that the Huns no longer dared to go south! Hearing this name, Shao Zisong said.

"Yes! However, the Huns were more than 700 miles away, so that the Hu people did not dare to go south and herd horses, and the soldiers did not dare to bend their bows and complain! What a situation! It's a pity that later the world was in turmoil, and the Huns became strong again, otherwise, where would there be so many things later! By the time of the Han Dynasty, the flying general Li Guangwei was the Taishou of Shangjun, and once led his troops to fight inside and outside Luguan, which made the Hu people shocked when they heard his name! Li Xin nodded and said with emotion.

"The name of General Fei is praised in the world! I heard his story when I was young! ”

"Time flies! In the blink of an eye, these heroes are already far away, and only this cold Luguan is still standing here. Generations of soldiers are stationed here, is it just for this cold city? Among them, they are all brave and loyal to defend the country and defend against foreign enemies! Li Xin sighed.

"General, rest assured, we and the soldiers of the Huashan Army will definitely guard this pass, swear not to retreat, and will never let the enemy cross this pass!" When Shao Zisong heard this, he couldn't help but get his blood surging and shouted loudly.

"Swear not to retreat, guard Luguan!"

"Swear not to retreat, guard Luguan!"

......

For a moment, the entire Guancheng people shouted in unison, as if to show Li Xin their determination.

"I know I wouldn't have sent you here if I didn't believe you! It's been three years, almost three years! It has only been more than three years since the establishment of our Huashan Army. But we have been fighting in the south and the north over the years, and there have been countless wars of all sizes! I, Li Xin, can say in front of everyone today that none of the soldiers of our Huashan Army are of a bad breed! Compared with other soldiers and horses in the world, it is far more than that! It is precisely because of you that our Huashan Army will become stronger and stronger, and people in the world will not dare to despise it! You are the pride of my Li Xin! Seeing everyone's excited expressions, Li Xin stood on a brick next to him, raised his hand to silence everyone, and then said slowly.

The soldiers guarding the place listened intently, and the snowflakes gently fell on their iron armor. Hearing his words, especially the last sentence, someone's eyes couldn't help but moisten~. In this bitter cold place, facing the cold and loneliness, Li Xin's words are the greatest affirmation of them!

Li Xin has an incomparably lofty position in the hearts of the officers and men of the Huashan Army, especially for those who have followed Li Xin from the beginning. Therefore, his affirmation is more glorious than anything else.

After spending the night in the land of Luguan and having a meal with the soldiers guarding the pass, Li Xin set off early the next morning. This time, he was going to the last stop of the trip, which was located in the place where Xiao Pass in Northland County was located.

If you want to talk about Han Xiao Pass, it is actually not accurate, because this place was actually established during the Qin Dynasty. But because the Qin Dynasty was too short, and the Han Dynasty inherited its Zuo, it is more accurate to call this pass the Qin-Han Xiao Pass.

In the land of Xiaoguan, there are actually several places in the later generations. Among them, it is located more than 200 miles northwest of Maling County, and is located at the intersection of the east and west sources of Malingshui, which is the Qin-Han Xiaoguan, and Malingshui is the ring river of later generations!

This place is located in a relatively open river valley and mountains, so the transportation is relatively convenient. In addition, the development time is relatively early, and a complete system has been formed since before the Qin Dynasty.

The reason why Hanxiao Pass is important is that if you go south from here, you can go directly to Xinping County, and then you will enter the pass in the south, which is less than 800 miles in total.

In addition, in the past, the straight road built by the Qin Dynasty happened to be located here to intersect! As a result, it has become a natural thoroughfare.

It is very convenient for the Hu people to go south, but in the same way, it is also the most convenient place for the Guanzhong forces to go north to fight against the Hu people. And it is precisely because of this geographical advantage that Malling County has been a place where merchants gather in the past.

But for Li Xin and Hua Shanjun, this place now has another meaning. That is the center of the entire northern border defense of Guanzhong. This is also the reason why Li Xin put Li Erhei here to guard.

From Xiaoguan to the north, you can enter the Hetao, and it is more than 300 miles away from the previous Zhujuan County. And to the east to Luguan, it is only more than 300 miles, to the west to Shimen, into Gaoping City, Wushi County, it is just nearly 300 miles away.

In this way, whether Luguan in the east is attacked by the enemy, or there is a problem in the north of Lujuan County, or the enemy has already hit Wushi County, Li Erhei, who is sitting in Maling County, can quickly mobilize troops and horses to support.

Moreover, these four places are places that affect the whole body, and if the Hu people in the north want to go south to Guanzhong, they must pass through this defense line of hundreds of miles. And no matter where you pass through, you will inevitably be threatened by other passes.

After all, since the time of the Qin Dynasty, this Xiao Pass has not only been as simple as a pass. It is more like the Hangu Pass, which was built by Emperor Wu of the Han Dynasty later, and is actually a defensive system.

Of course, in terms of the current financial resources of the Huashan Army, it is naturally impossible to restore the entire system like the Qin and Han dynasties. At most, we should pick some of the most important places and recover for the time being.

After all, if you want to build up the entire line of defense, it's not just about money. In particular, Li Xin didn't have much interest in this idea of pure defense, what he wanted was to stabilize his position first and block the enemy's peeping.

When the time is ripe, this line is probably of little use, because this place will eventually become the mainland!

On the way from Luguan to Xiaoguan, you have to pass through several obstacles guarded by soldiers and generals, and there are not many soldiers and horses stationed in these places, but they are all located in dangerous places. Moreover, they guard the beacon tower, and if something happens, they can immediately warn all directions, so that all localities can be prepared.

Comparatively speaking, these places are more difficult. Therefore, Li Xin went to comfort these soldiers, and they were all moved by this.

On the way, he rested in a barrier for one night, and when he hurried the next day, he directly entered the territory of Maling County. Li Xin did not go to the county seat of Maling, but rushed directly to Xiaoguan. In this way, when you return home, you can just pass through Maling and other counties!

Li Erhei was training soldiers near Xiao Pass, so the two sides just caught up. Although the weather was cold, Li Erhei and his soldiers were steaming, and they were obviously training very hard.

"After all, it is a world-renowned Xiongguan fortress! It's even more majestic than Luguan! It looks like the castle is almost finished! After entering the customs, Li Xin first looked at the city wall and couldn't help but say.

"Let's take this place relatively early, so it will naturally be repaired faster than the Luguan side. Besides, although this pass has been abandoned for many years, it is the world's Xiongguan after all, and the foundation is still there, so it is easier to repair! Li Erhei followed and replied.

With the fall of the Qin Dynasty and the establishment of the Han Dynasty, this Xiao Pass immediately shifted its location and moved to the side of Wushi County. This Xiao Pass is naturally slowly abandoned.

But no matter what, this is a key road for the Hu people to go south after all. Therefore, no matter who controls Guanzhong, they will inevitably garrison troops here. It is because of this that it was not finally abandoned.
