So the question is, the overall strength of the current demon barbarian race is not as good as Dachuan, so what about the future?

Don't forget, the demon clan also has a monkey with excellent qualifications and an immortal body.

Once that monkey breaks through the second grade, or the first grade, then who can stop it?

Do you rely on the salted fish of the Heavenly Master?

Then it is better to expect the old sow to go up the tree.

At that time, the demon clan will inevitably invade the Central Plains on a large scale, first, to kill Han Yun to take revenge, and second, to invade the Central Plains and expand their survival territory.

When that time comes, will the Western Regions sit idly by?

It will definitely take the opportunity to send troops to occupy the territory in the western part of Okawa.

If it was too early at that time, and now Han Yun is still thinking too far, then what about now?

He had already thought of the possibility of the demon clan bypassing the Jade Gate Pass to harass the people, and the Loulan Kingdom of the Western Regions had even done so.

So whether it is to prevent this kind of thing from happening again in the future, or to prevent the Western Regions from taking the opportunity to invade the western part of Dachuan during the future war, Han Yun must do one thing.

That is, to create two more natural risks.

One connects the Great Wall and Yumen Pass, completely sealing the passage into Dachuan from the north, and the other connects Yumen Pass with the west of the Qilian Mountains in the south, sealing the passage into Dachuan from the west.

If the army and caravan of your own country want to pass, you can just pass through the Yumen Pass.

If the enemy army wants to pass, it will have to face the head-on attack of the defenders of Yumen Pass.

And in this way, the defenders of Yumen Pass only need to defend the west and north, and the defensive forces can be more concentrated to deal with the enemy, and get twice the result with half the effort.

There is no need to worry that the Western Regions and the demon clan army will feel that they can't move the Yumen Pass and bypass from other places.

If the army of the Western Regions entered from the plateau mountain range thousands of miles west of Qinchuan, then they would not be able to wait for the logistics to be delivered, and they would not be able to go too far, and they would be starved to death.

Therefore, for them, the best way is to take the flat road of the Hexi Corridor through Yumen Pass.

The enemy would not be able to defeat the Jade Gate, and Han Yun never felt that his formation was really invincible in the world.

If the Demon Clan and the Buddha Sect were really determined to attack Dachuan with all their might, then his great array would also be broken under the joint efforts of several second-rank people.

At that time, these strong men will be responsible for fighting against the opponent's second grade, and they will have to rely on the soldiers of Yumen Pass to resist the enemy.

Thinking of this, Han Yun left Yumen Pass again and flew to the side of the Great Wall, and then, he took out the Gen and Kun beads in his Eight Wonder Beads, and used the power of the earth and mountains within him to start casting spells next to the Great Wall.

Under the stunned gaze of the soldiers at the end of the Great Wall, a tall ...... was more than ten meters high Strange things are rising from the ground.

To be honest, with the knowledge of the soldiers, it is really difficult to describe what kind of thing this is.

It's tall, it's wide, and it's flat.

Let's say it's a wall, it's a mountain stone structure.

Let's say it's a mountain, it's extraordinarily flat.

This is a mountain range, more than ten meters high and tens of meters wide, stable.

The sides of this man-made mountain range are similar to a smooth surface of 90 degrees, so that flies can slip on it, and above, there is an extremely flat runway, which can be used for the deployment and support of your own army, and also extends a female wall like the Great Wall, which is used to fire arrows to attack.

Han Yun built the mountain wall all the way, extending to the east of Yumen Pass, connecting with the northeast corner of the Yumen Pass city wall, and the height was the same.

In this way, even if the enemy army crosses the artificial mountain range with a ladder and enters the interior, Yumen Pass can also send cavalry from the east gate to kill those infantry, which is equivalent to closing the door and beating dogs and catching turtles in the urn.

And the enemy army will not cross the mountains too quickly, and it will be easy to defend.

If the enemy captures the top of the mountain range and attacks the walls of Yumen Pass against the corridor above, then they will have to face the overwhelming rain of arrows at Yumen Pass.

The passage is so wide, no matter how many enemy troops there are, the enemy troops to be faced on the wall of Yumen Pass are only at the front, and it is completely possible to fight more and consume the enemy army.

It can be said that Han Yun thought about all the tactics that the enemy could use, and then also studied the tactics against the enemy, so that the soldiers of Yumen Pass could be invincible.

Then, it took him a few days to build an artificial mountain range connecting Yumen Pass to the Qilian Mountains in the south, completely blocking the terrain that was originally wide open.

Then, he went to Nie Ze and asked him to send troops to two new mountain ranges, build beacons and forts, and arrange soldiers to garrison and patrol guards.

It's all done according to the standards of the Great Wall.

This can be called a miracle scene, and the soldiers and civilians of Yumen Pass were dumbfounded, and at the same time, they also praised the miraculous achievements of Zhenbei Hou.

This is a great cause that will benefit the present and the future.

With these two towering and precipitous Great Wall mountain ranges, they no longer had to worry about the enemy army bypassing the Yumen Pass to attack the people.

Yumen Pass has really become a natural danger pass.

After Han Yun finished these things, he returned to the Jade Gate Pass to rest.

At the same time, the reinforcements led by Zhao Long and Xie Xing also came to the west of Qinchuan and began to kill all the enemy troops they saw. m..

The western part of Qinchuan is all high mountains and mountains, as well as forts built on the top of the mountains and passes, which are all military strongholds, and many have been defeated and occupied by the enemy, but there are many more forts that have not been occupied.

In these forts, there are not too many enemy troops stationed, and the enemy troops are more concentrated in the saddle area between the mountains, where the terrain is relatively gentle, suitable for large armies.

But there are not many people stationed here, the enemy troops are scattered and stationed, and at the same time, because of the grain and grass, they have a large area of famine, and many bark and grass roots in the mountains and forests have been eaten by them.

Now both they and the defense forces are riding tigers, and food and grass are in short supply.

They cut off the food routes of the defense army, and at the same time, because their own numbers were too large, and it was difficult to transport grain and grass in the country, resulting in their stomachs that had been hungry for a long time, and even many wounded soldiers were starved to death without food and grass.

When the Zhenbei Army and the Yuejia Army arrived, they were faced with such a group of enemies who were difficult to hold knives.

Then what else to say, just hit it!

The wolf-like Zhenbei Army and the Yuejia Army charged at the enemy.

Zhao Long and Xie Xing's tactics were very simple, the two flanks of the Yuejia army were outflanked, and the central part of the Zhenbei army broke through, and after breaking the enemy camp, they killed the enemy army.

The enemy had no choice but to run to both sides, and then they would encounter the outflanking Yue army.

Zhao Long and Xie Xing used this tactic to defeat one enemy garrison after another, and easily uprooted those fortresses where the enemy troops were stationed, and the war went smoothly.
