After the northern border was determined, the existence of the "unarmored battalion" was enough to deter the raids of the northern nomads.

Under the gap of absolute force, it is believed that it will not be long before the rules of Heian City will be introduced to the wider grasslands of the north, and thus become the most desirable refuge for those nomads.

After eliminating the threat from the north, Li Yan once again looked at Yanmen Pass in the south.

Due to the existence of Yanmen Pass, the daily communication between Ping'an City and the people of Wei was seriously hindered.

If those ordinary people can't even get out of the door, and they still talk about the principles and policies of gathering manpower, it is simply a tree without roots and water without a source.

Therefore, the problem of Yanmen Pass must be solved.

On the computer, I opened the high-definition digital map recently collected by the staff of Guangliang Surveying and Mapping Company, and drew a circle centered on the Ping'an City under construction.

After seeing the length of the radius of the circle, Li Yan smiled.

The entire section of the mountain range where the Yanmen Pass is located has been covered by this circle, and the farthest point has even included most of Dingxiang County.

Within the control of Ping'an City, no force can raise swords and soldiers, which was made clear by Wei Minsheng at the beginning of the city's construction.

Since the area within a radius of 200 miles of this Ping'an City is under the control of the Huaxia Kingdom, this Yanmen Pass has also lost the significance of preventing the invasion of the Xianbei people.

Li Yan informed the interpreter who had announced the territory to the Tuoba Liwei tribe, and after explaining some things, he asked him to go back to Yanmen Pass to pass the word first.

Then, he took ten members of the Chinese Self-Defense Force to the outside of Yanmen Pass again.

The towering green mountains are still the same, if it is Wei Minsheng, he may still think about how to protect this world-famous Xiongguan.

But for Li Yan, this so-called Xiongguan is nothing more than some earthen cities built of stones.

Even with the same use of stone, the educated laborers of the Huaxia Kingdom, who had mastered the new tools, built a that looked much more pleasing to the eye than the so-called Xiongguan.

Coupled with the fact that it already has absolute air supremacy, the significance of this Xiongguan is not so important.

However, due to the large number of buildings, many checkpoints, and complex terrain in this pass, if not properly handled, it is likely to become a shelter for rogues.

If it was those Wei soldiers who were guarding the pass, he could have threatened the King of Wei with force to withdraw his soldiers from Yanmen Pass.

But if Yanmen Pass falls into the hands of those rogues, there is only one way to clear it by force.

In roadway warfare in complex terrain, the advantage of thermal weapons is almost completely limited, and it is very difficult to take it down without hurting a single bit.

Li Yan's solution was simple and rude, using a bazooka to open the way, and directly blasted off the outermost gate of Yanmen Pass.

Then he forcefully demanded that the garrison of Wei immediately withdraw from Yanmen Pass, and if they did not withdraw the next day, they would use more violent weapons to forcibly destroy Yanmen Pass.

The words of the interpreter, as well as what he saw and heard during this time, especially the hundred-mile pursuit of 2,000 men and horses by 20 people, made these Wei guards unable to resist at all.

Just kidding, those people of Huaxia can not only fly in the sky that the eight bull crossbows can't reach, but the other swords and arrows are even more powerless.

Coupled with the terrifying weapon that smashed the door when it was closed, all the soldiers on the gate of the wild goose gate were only beaten, and they had no power to fight back.

In the case of absolute military superiority, people can be regarded as saluting first and then soldiering.

The words have come to this point, if you still don't know what to do and what to do, you don't know how to advance or retreat, and you can't blame others for your own death.

Li Yan's purpose in doing this was to make the Wei guards' soldiers clearly see the gap between their military strength and that of the Huaxia State.

When two adults fight, more often than not, when they are evenly matched, everyone thinks that they will be the one who wins in the end, and this fight can be fought.

And a child fights with a strong man, it can only be in a reckless situation, the child completely gives up his own safety, maybe he can make the strong man injured, but if you want to win, it is very difficult.

When the difference in strength between the two sides is not large, violent conflict is most likely to occur.

But if the difference in strength between the two sides is like an ant and an elephant, this fight will not be fought at all.

Because, a small ant can't cause any damage to the elephant even if it is broken to pieces, and such a gap is undoubtedly very desperate.

For an elephant approaching with its head held high, those little ants can only avoid its edge, and try to stay away from the elephant to avoid being devastated by the elephant.

Obviously, those Wei guards' guards retreated, and in such a situation, personal bravery could no longer stop the progress of Huaxia Kingdom, and take a step back to open the sky.

Besides, if this Yanmen Pass falls into the hands of this Huaxia country, with the strength of twenty of them to chase down two thousand Xianbei warriors and flee in embarrassment, where would those Xianbei people dare to spread wild here.

Arranging the guards here to other nearby passes can also strengthen the defense capabilities of other places, which can be regarded as a reason to comfort yourself.

Seeing that the garrison had begun to evacuate, Li Yan directly used an excavator to tear down all the checkpoints and walls built on the side of the main road to ensure that the entire gallop road could be unimpeded.

Using an excavator to demolish those stone and wood buildings is a bit overkill.

Those wooden houses with a teasing structure are like tofu in front of the bucket.

Everywhere the bucket went, there were only ruins and rubble.

Tear it down all the way, and it's like a bamboo.

For those walls made of earth and stone, the stones are not tightly bonded at all, and the stability of the structure can only be ensured by gravity and friction.

But such a structure, in the face of the powerful machinery, has no advantage at all.

Although demolishing the wall was a little slower than demolishing the house, watching the large pieces of stones easily thrown aside by the excavator, those original Wei soldiers still felt a chill in their vests.

As soon as you dig down, even hard stones can be dug into pieces, and if you touch them, there will be several holes, and if you dig into a person's body, it may be a puddle of flesh and mud.

Such a steel monster, if it is encountered on the battlefield, several times the border army, who can resist it?

The last soldiers to retreat cowered at the back of the line, staring in horror at the steel behemoths that were rampaging through the major levels.

The panicked and small footsteps all revealed the helplessness in their hearts.

A little farther away from that thing, even if it was only half a foot away, it seemed as if I felt a little farther away from danger.
