It was precisely because they knew the danger of Black Wind Mountain that Li Sheng and the others tried their best to dissuade Su Qi'an from going to this adventurous place, even if they asked the imperial court for help, they didn't want to see Su Qi'an lose his life.

They didn't have long contact with Su Qi'an, and they didn't have too deep feelings for him, but just showing their hands under Mengzhou City just now, and deterring these Mengzhou officers and soldiers, was enough to make them obey Su Qi'an's orders.

But Su Qi'an wanted to personally lead the troops to Black Wind Mountain, even if it was just to talk, but he dared to bring it up, and he would completely conquer the three of them at this moment.

What is the boundary of the Black Wind Mountain, they know better than anyone else, it can be said that there is no life, whether it is Mengzhou or Yuezhao across the mountain, they all regard the Black Wind Mountain as a natural barrier, and it is impossible for anyone to cross it.

However, in order to reverse the war situation in the two northwestern states, Su Qi'an not only advanced and retreated together, but also took the lead, which had never been seen among the senior officials sent by the imperial court in the past.

They are all military generals, so they can naturally understand what Su Qi'an said, it doesn't seem to be fake, and there is a strong firmness in their words, and no one can advise them.

This is the Shangguan they admire, you don't have to do a lot, you don't have to show a lot, you just need to stand up at a critical moment, his personality charm will be infinitely magnified at this moment, and for martial artists like them who guard the border, they like this kind of person the most.

finally ran into such a brave, resourceful, and charismatic official, and they naturally didn't want to see Su Qi'an sent to death, so they tried their best to stop it.

With the kindness of Li Sheng and the others, Su Qi'an naturally understood that the reason why he did this was not out of his ability, but because he had to do it as a last resort.

The current battle situation in Mengzhou is changing too fast, even Su Qi'an is unpredictable, in order to reverse the situation of the war, it is surprising to send troops.

And if you want to win by surprise, crossing the Black Wind Mountain is the most strange move, everyone knows that the Black Wind Mountain is a dead place, but the more this is the case, the more Su Qi'an has to do the opposite.

As long as you cross the Black Wind Mountain, arrive at Yuezhao, and join forces with Su Fengwu, with Su Fengwu's prestige, you can't think that you will not fight the soldiers of the people and persuade the countries of the Western Regions to withdraw their troops.

In the second peace talks, Tong Zhan makeup gardener infiltrated Yuezhao, and his task was to represent Su Qi'an, and wanted Su Fengwu to make an appointment with Mu Tuoer and let him unite against the water.

Among the countries of the Western Regions, the strongest ones are the Hui Evil, Yuezhao, and Dazhi, and now the Saktu people are not in the rear, and they have 70,000 coalition troops and Ganzhou troops fighting fiercely.

It just so happened that his rear was once again in the void, as long as he could talk to Mutor, let him turn against the water, and unite with Yuezhao to stab Saktu in the back, he would definitely catch Saktu off guard.

This plan was good, but when the two sides went to war, Su Qi'an found that he was a little too confident in this plan.

Thinking that relying on Tong Zhan and a dozen or so people, he could convince Mu Tuoer was a bit too self-righteous.

Mutol is also the lord of the big branch, and the big branch can stand at the forefront of the countries of the Western Regions for many years, which is enough to show that Mutol is not a useless waste.

If you want him to turn against the water, it is impossible to rely on Tong Zhan alone for a dozen or so people, if there is no benefit, and if he fails to see the possibility of Saktu's defeat, how to talk about it is destined to be unnegotiable.

And it happened that the Battle of Mengzhou broke out, and Su Qi'an thought of the Black Wind Mountain, which was regarded as a grave by the two northwestern states.

In order to successfully cross through, Su Qi'an only brought the 5,000 cavalry divisions under Ermeng this time.

This cavalry division is the trump card of the Dongshan Army, as long as it can successfully cross, it is only a matter of time before the empty countries of the Western Regions in the rear are swept away.

Although his plan this time is very risky, it is much better than putting his hope in the so-called imperial court reinforcements.

For the persuasion of the three people, Su Qi'an was silent for a while, shook his head and said, "This overseer, I know the good intentions of the three of you, but now that the war is urgent, if you want to turn the tide of the war, you will have to win by surprise, this overseer has already decided, lead five thousand cavalry across the Black Wind Mountain, and Mengzhou City will ask you." ”

Looking at Su Qi'an's very firm face, Li Sheng and the three of them knew that how to persuade them, they were afraid that it would not have much effect, so they could only nod helplessly and tell Su Qi'an more.

Inform Su Qi'an of some of the geographical conditions they know about Black Wind Mountain without reservation.

Su Qi'an listened carefully to these, although he had heard most of what the three of them said, but it was also the intention of the three of them.

Through the conversation, Su Qi'an could feel that the three of them were worried about themselves, and the three of them could value themselves so much, and the previous battle under the city had a great effect.

After all, annihilating the cavalry with infantry, although the infantry has an advantage in numbers, but facing the Darong cavalry, this is to fight the strong with the weak, and still achieve all the annihilation, which is completely beyond their understanding.

Anyone else would be stunned when they saw this scene.

Su Qi'an was able to do this, mainly because of the siege formation, which was created by Su Qi'an, but it was also combined with the experience accumulated in the southern and northern wars in the past few years.

Of course, what helped him the most was a military book that Amurai left for him before he died.

In addition to recording the southern and northern wars of Amurai for so many years, this military book also has deep insights into the formation coordination between armies.

Amurai himself was a master of maneuvering, and his use of cavalry was perfect, and in the book of war he left behind, there is a record that he mentioned how to use infantry phalanxes to cooperate with each other to annihilate a small group of cavalry.

It's just that this formation Yamulei has not been completely perfected, only a third of it has been drawn, and a few key ideas have been proposed.

He was quite interested in this way of defeating the strong with the weak, and in the past few years of campaigning, he finally let him improve the infantry formation of the besieging cavalry little by little.

And the annihilation battle under the city of Mengzhou just now was the first show, and in general it was not bad, although the casualties were very large, Su Qi'an was still very satisfied.

In any case, to be able to besiege the cavalry with a large number of infantry and annihilate it, without the casualties of the other side, is a success.

Of course, this kind of infantry annihilation cavalry formation is not 100% restrained, and there are still great flaws.

The first infantry to be mobilized is more than one type of infantry, including heavy infantry, shield soldiers, crossbowmen, halberd soldiers, and death infantry... and so on, there must be a very high degree of tacit understanding between each other.

In the siege, it is not static, it must be constantly changed according to the current situation, but if the other party finds a flaw, it is very likely to break through directly, and the siege formation that has been arranged with great difficulty will be broken.

And even if there is a tacit understanding between the various arms, there is an upper limit to the number of cavalry to be annihilated after all, and the annihilation of 5,000 cavalry in one breath like today is the limit.

And it was annihilated by 10,000 infantry, and to be honest, there was more or less luck in it.

The Rongguo cavalry that infiltrated this raid may not even have expected that they would be besieged by a force of 10,000 infantry, and they were all annihilated.

It is estimated that the battle will be fought to the end, and the remaining Rongguo cavalry will have long since died, consciously breaking through hopelessly, and losing their fighting spirit, but all the cavalry that appears in this army are not afraid of death, do not retreat from the battle, and have a strong desire to survive, and will never be completely annihilated, at least more than 1,000 people can run.

This is also the reason why Su Qi'an won the battle under the city, and instead of gathering his army, he directly launched a counterattack against the Rongguo army that invaded south.

This kind of fighting method of defeating the strong with the weak and annihilating the cavalry with infantry is not always as many as possible, and sometimes there are too many troops, but it becomes a burden.

As long as it is not a burden, Su Qi'an will not continue to divide his troops, let alone risk crossing the Black Wind Mountain.

In a war, a partial victory somewhere cannot change the situation of the war, at most it can only be used to boost morale.

If you want to turn the tide of the battle, you have to surprise and break the surface with points, and only in this way can you bring about changes on the entire battlefield.

Looking at the soldiers gathered one after another under the city tower, Su Qi'an waved his hand at Li Sheng and the others, then turned around and went downstairs, and then turned over and got on his horse.

In front of him, Song Biao, Chen Dao, and Er Meng waited for a long time, and the three of them had smiles on their faces, trying their best to keep themselves restrained, and did not show worried looks.

When Su Qi'an led his troops to Black Wind Mountain, the first thing he knew was the three of them, and when the three people who learned the news, their first reaction was the same as Li Sheng.

They all tried their best to oppose it, but their opposition had no effect, and once Su Qi'an decided, no one could pull it back.

Since the matter was decided, the three of them didn't say much, and watched Su Qi'an lead five thousand cavalry away, and disappeared from everyone's sight after a while.

Not long after Su Qi'an left, the three people who came back to their senses each greeted each other, and then shouted.

"Brothers, Sir has set an example for us, and then ours, there are countless people of Da Liang watching us behind us."

"This battle can only be won, never defeated!"

"Brothers, follow me!"

With an order, the three of them rushed out first, and immediately three more long formations like a torrent appeared behind them, and there was no end in sight.

As the three of them set off, Li Sheng did not hesitate, and then led his own group of men and horses to leave, and the remaining two lieutenants stood on the city tower, looking at the four torrents that were leaving in four directions, all with solemn expressions, clenching their fists and looking away.

On their faces, there was no sadness, but inexplicable excitement, the 40,000 troops who set off from Mengzhou City, their bodies were no longer the low morale just now, but the monstrous war intent.

There is a great determination to fight with the soldiers who invaded the south at any time.

The arrival of Su Qi'an not only allowed them to find the backbone, but also clarified the direction of the battle behind Mengzhou.

What's more, their overseers and commanders are all leading the way, and if they continue to mess up, it will be a real shame for themselves.

The high morale was completely recovered at this moment, and the next battle of Mengzhou will be seen.

This kind of division of troops is precisely to see clearly the geographical advantages of Mengzhou City and the other four military towns, and if the four military towns and the four directions surround the middle of Mengzhou City, if they are properly arranged, they will be able to achieve a real impregnable wall.
