Unlike Ganzhou, most of the boundaries of Mengzhou are barren, but there are some oases near Mengzhou City, and it is precisely because of this that four military towns have been established along the perimeter of Mengzhou City.

The loss of the other three military towns is only the periphery of Mengzhou City, and only the four military towns close to Mengzhou are the top priority, once lost, the middle Mengzhou City will be completely isolated.

But if it is arranged properly, it can be truly impregnable, and the 5,000 Rongguo soldiers who infiltrated in before were given an opportunity because of the scarcity of soldiers in the surrounding military towns and improper defense.

Now, under Su Qi'an's rectification, the soldiers of Mengzhou have not only regained their low morale, but also have a goal, with four commanders who say the same, as long as the four military towns are united, it will be even more difficult for the honored soldiers who are heading south to take one of the military towns as easily as before.

This is also the reason why Su Qi'an dared to lead 5,000 cavalry and went straight to the Black Wind Mountain on the western border.

As soon as Su Qi'an left, the two military towns of northern Mongolia and eastern Mongolia were attacked by the Rongbing, and the two sides fought for a while, but this time the Rongbing generals who went south obviously felt wrong.

After continuing to attack for about half an hour, the military town in front of him could not be taken, which made the Rongbing generals puzzled.

You must know that the previous three military towns were conquered by them, which was called an easy and effortless one, but now, the same military town, the same Mengzhou soldiers, only about an hour has passed, but they are judged to be two people.

The Rong general's face was solemn, and he didn't say anything, but continued to give the order to attack, they didn't believe it, almost half of the border of Mengzhou fell into the hands, how could they be stopped by this small military town in front of them.

This time, they have gathered 70,000 or 80,000 troops, even if the defense of these military towns in front of them is comparable to an iron wall, it is called intensifying the attack, and the Mengzhou soldiers in front of them will be consumed.

Countless soldiers rushed towards the military town in front of them like a tide, and suddenly, the killing shouts shook the sky...

And Su Qi'an, who led 5,000 cavalry, finally arrived at the Black Wind Mountain, which terrified Li Sheng and many other generals, after running wildly for an hour.

Su Qi'an's surroundings are barren, at a glance, empty, unobstructed, only endless yellow sand, these are okay, especially looking ahead, in addition to a barrenness, there are gusts of black wind in the air.

This is not some kind of demon or monster, but the sand on the ground is blown up into the air by the wind, which can blow the yellow sand on the ground into the sky, which is enough to show that the environment here is harsh.

This is only the periphery, at the end of the line of sight, there is a dark blur, it is the swept sand and dust, just watching from a distance, giving people a strong shock.

Su Qi'an retracted his gaze, took a deep breath, waved his big hand, and his cavalry quickly took out a piece of cloth from his arms, wrapped his head, and at the same time turned over and dismounted, and each of them was connected by thick ropes around their waists.

These are still secondary, and the most striking thing is that ten carts were pushed out of the army.

The car looks like an ordinary cart with a single wheel in the front and two wheels in the back, but in the middle of it, there is a bronze figure about two feet high.

This bronze man is very special, one arm is stretched out, pointing forward, the most amazing thing is that no matter how the cart changes direction, the direction of this bronze man's arm has never changed.

As the cart moves, you will find that there are many gears of different sizes on the bottom and inside the car, which looks very delicate.

These ten special carts are the key to whether Su Qi'an can successfully cross the Black Wind Mountain.

According to Su Qi'an's estimate, the terrain of Black Wind Mountain is special, and it is likely to be covered with a special magnetic field, under the influence of this magnetic field, it is difficult for anyone to walk into it.

Although Liangren was smart, Su Qi'an found that in this era, there were no instruments like Sinan and compass, so according to his own speculation, Su Qi'an deliberately asked the people in the R&D department to build himself a navigation instrument similar to Sinan.

According to the materials stored in Da Liang, it took a long time to build this North Pointing Car, in order to verify his conjecture, Su Qi'an immediately ordered his subordinates to push the North Pointing Car into Black Wind Mountain to test the effect.

The soldier moved quickly and stepped into the Black Wind Mountain Realm, and as the wind in front of him hit, it blew like a knife and made the north car creak, but no matter how he went, the bronze man's arm pointing to the north never changed.

Looking at this scene, Su Qi'an breathed a sigh of relief in his heart, this is the same as he thought, there is really some kind of special magnetic field in Black Wind Mountain.

Although he held the north car, Su Qi'an still didn't dare to be careless, in addition to the special magnetic field in the Black Wind Mountain that affects ordinary people who can't distinguish the direction, this black storm is also a must.

If you are not careful, the group will move forward cautiously step by step, and it is likely to be swallowed up by the sudden black storm.

In order to protect the soldiers of the North Steering Car who led the way in front, Su Qi'an deliberately installed two stout and wide iron chains on the body, and the other end of the chain was held by at least more than 100 soldiers in their rear army.

Before entering the Black Wind Mountain, Su Qi'an had already given an order with a group of subordinates, preferring to advance slowly step by step, rather than move forward carelessly and rashly, and those who violated the order would be beheaded.

Under the arrangement of many thorough preparations, Su Qi'an, who had a solemn face, waved his big hand, and the next moment, five thousand Dongshan cavalry, connected by ropes, stepped into the Black Wind Mountain little by little, and after a while, the black sand in the sky flooded everyone's figures.

What Su Qi'an should have done has already been done, as for whether he can successfully cross the Black Wind Mountain, he can only leave it to Providence.

……

When Su Qi'an arrived in Mengzhou, he adjusted the deployment in the fastest time and stabilized the situation, and at the same time, in Ganzhou, Wang Zhenshan's Ganzhou soldiers and Saktu's Western Regions coalition army, the fierce battle between the two sides also reached a white-hot situation.

As Su Qi'an expected, after the troops were divided into three routes and successfully captured five military forts, after finding that the casualties were too large, Saktu immediately changed his tactics, concentrated heavy troops, and stormed Longquan in the middle.

Xie Cang, who was in charge of guarding Longquan, had been waiting for a long time, and in the next two or three hours, the two sides fought fiercely.

At the height of the war, there were nearly 30,000 men and horses who fought together and stormed the Longquan military town.

In the face of such a menacing situation, Xie Cang was not afraid at all, and commanded his 20,000 horses to fight against him, and in the later stage of the war, Xie Cang even took the lead in leading a surprise army to raid the Central Coalition Army.

But even so, Xie Cang's surprise attack still caused a large number of casualties to the coalition forces in the middle.

When the strength of the troops is enough, the number of military forts established in front of him to block it basically has little effect, and the other party's purpose is only one, to penetrate the dragon spring in the middle with force, as for the many military forts in front of him, he did not pay attention to it at all.

Therefore, Xie Cang thought about it for a long time, and immediately gave up the idea of blocking layer by layer, scattered his troops, and walked through various military forts, fighting an ambush from time to time, and running away after the fight.

If the other party sends heavy troops to pursue, Xie Cang will send out a surprise army, directly sneak around the rear, or interspersed with division and surrounding, and eat it little by little.

If it's a small force, lure it to a place where you can ambush it, and eat it in one bite.

It was by relying on this flexible and changeable style of play that Xie Cang's 20,000 people not only did not fall into the disadvantage in the face of the 30,000 people of the Central Coalition Army, but even played with ease.

Under this continuous harassment, after two or three hours of heavy fighting, the Central Coalition Army could not bear it, received orders, weakened the offensive, and then temporarily retreated to the captured military fort, waiting for the next move.

The Central Route Coalition Army took the initiative to end the battle, Xie Cang did not send troops to pursue, and also occupied several favorable military forts as forward positions, and the large army withdrew into Longquan Military Town to rest.

In this battle, it is roughly estimated that the casualties of the Central Route Coalition Army were at least seven or eight thousand, and similarly, Xie Cang's casualties were also quite few, three or four thousand.

The other party stopped attacking for the time being because he couldn't afford it, and in the same way, Xie Cang also had time to rest, this battle would not end in a while.

The test is the patience of both sides, as short as ten days and half a month, or as long as two or three months, and the battle of Ganzhou can be over.

If the other party can be forced to take the initiative to withdraw its troops and temporarily stop the attack, it will be regarded as a victory, at least the Longquan Military Town is still in their hands.

The temporary end of the war in Longquan Military Town does not mean that the war in Tiannan and Wuwei will also end together.

Xie Cang, who finally had time to rest, soon came to him with a military report about the other two military towns.

The Western Regions coalition army was frustrated in the middle and stopped the attack, but Tiannan and Wuwei were in a stalemate.

It is obvious that the key target of the other party is the central Longquan, and as for Tiannan and Wuwei on the left and right, they are responding.

The total casualties of Tiannan and Wuwei are also four or five thousand, and the other party's consumption is also very large, estimated to be six or seven thousand, so far, the casualties of the Western Regions Alliance are almost 20,000, and they are about 10,000.

The battle loss ratio of the two sides is basically one to two, from the current point of view, they have the upper hand, but the more this time, the more they can't take it lightly, with Wang Zhenshan's understanding of Saktu, this person is proficient in the way of using soldiers, and it is impossible to lose so many men and horses in vain.

Wang Zhenshan specially sent a military report, asking Xie Cang to be cautious and cautious, and to pay attention to Saktu's movements at any time, and not to be exploited by him.

Wang Zhenshan's reminder, Xie Cang naturally put it in his heart, from the current point of view, Saktu still has the intention of attacking Longquan in the middle lane, if he is complacent, he is likely to overturn carelessly.

After all, at this time, the only thing he can rely on is himself, as for the defenders of Tiannan and Wuwei, they have been entangled by the left and right coalition forces, and they will want to help for a while, which is basically impossible.

Putting down the military report in his hand, Xie Cang's expression was solemn, and he ordered his subordinates to be vigilant and defensive, and not to give the other party a chance.

Only by trapping Saktu to death in Ganzhou and being in a dilemma can Su Qi'an's pressure in Mengzhou be relieved.

"I don't know how Brother Su is now." Xie Cang muttered softly.
