After all, Zhang Wei is a general, and he is also the number one military minister under Zhang Lu, and he still has a little IQ in leading troops.

He knew that the cavalry could pursue at night when taking the main road, and the infantry must have a vision when they climbed the mountains and cut corners.

But he would not waste any time, so he immediately ordered all the infantrymen who were to set off on the fourth watch tomorrow to rest and sleep early, so that they could go on their journey full of energy when the time came.

At the same time, Zhang Wei took advantage of the last few hours before the main infantry attack, and cautiously reviewed the military situation around the area in recent days - especially where this Han envoy came from, he must find out, otherwise he will not be able to sleep when he sends out the army.

Zhang Lujun's scouts, sentinels, and meticulous work were operating at full speed, either summarizing and reporting the clues found in the past few days, or limiting the time of midnight, immediately going north to search the road, even if it was too late to find the Han army, at least some people were arrested and tortured.

Zhang Lu didn't sleep well in the middle of the night, and after the third watch in the second half of the night, a few small colonels in charge of the fine work woke him up and reported the latest situation:

"General Yu, according to the torture of the captured people, in the area of Hechi in the north, there have indeed been soldiers and horses dispatched recently, and we have made every effort to spy on them, but we only know that Huangfu Song broke Han Sui in Chencang half a month ago, and the Han envoy who secretly crossed should have been stranded north of Chencang before, or Tunyi County, or Tunmeiyang, and only after hearing that Huangfu Song broke the Liangzhou thieves, he crossed the Qinling Mountains from Chencang."

"There are soldiers and horses in the river? How many people? Whose flag? Coming at us? Zhang Wei nervously got up from the bed.

The little colonel said uncertainly: "It seems that there are not many people, or rather, there are quite a lot of them at first, and then a lot of them have gone." The Han army's movements are very secret, some hunters, medicine farmers and people have been detained, a very few escaped, after we asked, they all said that the Han army was going to go down to identify, roundabout around Tianshui. As for the banner of the generals of the Han army, it is the left general Huangfu Song. ”

Zhang Wei thought for a while: Since it is the banner of Huangfu Song, and Hechi had many soldiers at the beginning, and then disappeared part of it, it is very likely that it is really a temporary pursuit and search force after the collapse of Chencang City.

Detouring from the Qinling Mountains to Tianshui, although there is a suspicion of deliberately taking a long road, it can also be explained. Maybe Han Sui was too blocked in the Weishui River Valley in Longshan, and Huangfu Song couldn't go around behind the enemy to attack the front and rear of the surprise troops.

This kind of military operation really needs to be kept secret, because if Han Sui knew about it in advance, the Xiliang army divided its troops from Ji County to the south, camped at the Qishan Pass, and blocked Huangfu Song's partial division in the valley, then it would not be able to get out.

After thinking about these causes and effects, a stone fell to the ground in Zhang Wei's heart, and he muttered to himself: "I have long heard that the Huangfu family was a general in the era, and he didn't care about the government, he only knew the military, and he didn't have any friendship with Da Honglu and Da Zongzheng. I think he will not be able to fight heavily for those Han envoys who soothe the Quartet, even so, our army can rest assured that they will pursue the Han envoys with all their might! ”

Da Honglu is in charge of diplomatic affairs with the barbarian Hu people, and Dazong is in charge of thoroughly investigating the clan. Huangfu Song is too famous, and his friendship with the various ministries of Jiuqing is also an important piece of information that the surrounding warlords have long mastered.

Zhang Wei knew Huangfu Song too well, so much so that now he misjudged under the dark lights.

After another shift, Zhang Wei personally led 5,000 foot soldiers as the Chinese army and set off to chase Li Su.

At the same time, he also agreed with Yang Ang, the deputy general who stayed at Yangping Pass, to communicate the method: if the combat effectiveness of the personal guards around the Han envoy was too elite to take it for a while, then he could light the beacon smoke in the high place at any time, and Yang Ang could add troops to help the battle as appropriate.

……

In contrast, Li Su's troops were not in a hurry, he knew that he had distanced himself from Zhang Weijun enough.

So the night before, he lit a torch and walked south along the east bank of the West Han River for about fifty miles, and seeing that the time was almost at the end of the night (nine o'clock), he ordered to find a relatively steep place next to the road to camp and rest, and sleep well to recuperate. At the same time, do not forget to divide the sentinels in batches.

Also, because they were traveling lightly, they didn't bring tents, but only used some extra pack horses to carry felt blankets to keep warm.

In the middle of the second lunar month, the night was still a little cold, and there was no time to build a strong camp. Li Su ordered the soldiers to hastily cut down dozens of large trees, throw the main trunk on the main road of the valley to set up barricades, and use the branches to build a bonfire to keep warm.

A thousand elite soldiers slept for most of the night, and when it was the fifth watch of dawn, the last group of Zhou Tai, who was on duty at night, ran to wake up Li Su and Zhao Yundianwei, and asked all the soldiers to extinguish the embers of the bonfire so as not to expose their whereabouts.

Zhou Tai handed Li Su a piece of linen soaked in cold mountain spring water to wipe his face, and asked for the order: "Zhonglang, I heard the sound of a large number of horses' hooves at the Beishan Pass, and I can't see it clearly, I'm afraid that there are hundreds to thousands of cavalry chasing after me, it should be Zhang Wei's pursuers, only a few miles away from us, what is the right thing now?" Is it hiding or running in wartime? ”

Li Su wiped his face with a wet linen cloth, he was so cold that he was more awake, and he shook his head vigorously:

"Zilong, are you sure to repel the enemy army for a while? I don't know how many enemy troops there are...... But I estimate that according to the military situation before the war, if it was all cavalry, it would not exceed 3,000 horsemen, and there were not many horses in Hanzhong, and Zhang Lujun's war horses were all sold in the Qinling Valley in the north. ”

Zhao Yun promised: "Zhonglang rest assured, the art of war cloud 'a hundred miles and those who seek profit can pout the general', calculate the time, Zhang Wei got the report yesterday evening, sent cavalry to gallop here all night, and rushed to the night for more than 100 miles, it is already sleepy and tired, our army slept all night, to wait for work, as long as a little sober, it is not a problem to ambush and break several times the enemy!" ”

Li Su nodded, secretly thinking that when he first got up, Zhao Yun's IQ was still relatively online.

He is a weak scholar and a low blood pressure demon king, and he can't move his brain without breakfast.

He thought about having breakfast by himself, so he couldn't help but ask Yin Shuyan in a hurry: "The soldier woke up in a hurry, do you have time to use some dry food to recover your strength?" ”

Zhao Yun said with a smile: "How can there be time to eat, it's not too late to kill and retreat the enemy army, and the enemy army will definitely not eat when they are in a hurry, so we won't suffer." ”

Li Su rubbed his face: "It's better to let the soldiers drink saliva and slow down." ”

"It's nature."

After Zhao Yun finished speaking, he went to arrange for the soldiers to get on the horse, line up, arrange the formation, and ambush in an orderly manner. About a few minutes later, the cavalry of the Zhang Weijun in the valley caught up.

……

Yang Ren and his younger brother Yang Ang are the two most powerful lieutenants under Zhang Wei, and they are also rare brave men in the Hanzhong Army.

During the military meeting last night, Zhang Wei himself decided to lead the Chinese army to pursue, and let Yang Ren lead the cavalry to entangle Li Su and Yang Ang to stay at Yangping Pass.

Therefore, Yang Ren rode his horse with torches and marched all night, only taking a little rest twice in the middle, each time only for a quarter of an hour or two, letting the soldiers drink some water and eat something, and the rest of the time was on the road.

Yang Ren was quite arrogant, and he also knew that it was a problem to march in such a hurry.

But because I heard that the Han envoy's guards were only a few hundred, and he had two thousand six hundred horsemen, it didn't matter if the men were sleepy and the horses were short, the pile would kill the enemy!

At this moment, the front army finally came with a little refreshing news: "General, the valley road in front has been broken by a big tree barrier, and it needs to be moved away to continue the pursuit." ”

Yang Ren was slightly nervous: Could it be that the mission still dares to ambush himself? Or is it because you know that you may be chased, and you just want to destroy the road and delay the pursuers to buy time?

"The whole army is on alert, and some people are assigned to move the trees!" Yang Ren cautiously ordered.

Fortunately, his doubts did not last long, and the mystery was revealed.

Behind the pile of wood, and even on the slopes on both sides, hundreds of Danyang soldiers or bows or crossbows got up one after another and began to release arrows, and for a time hundreds of arrows were cross-fired, shooting Yang Ren's own soldiers who were blocking in front of the pile of wood.

Yang Ren was in a hurry, but he still had hope in his heart: "There are not many messy trees!" Don't panic! Get out of here! ”

Li Su didn't spend much time last night, after all, he didn't know if the enemy would come, otherwise the preparations would be wasted.

So much so that Yang Ren felt that with a little more corpses and a pile of wood being bulldozed, he could rush over with a prancing horse, which was nothing more than a loss of speed and impact when climbing, and he also had to avoid obstacles to delay some time and make the troops a little disjointed, which didn't seem to be a big deal.

In the face of absolute combat superiority, there is no need to be afraid of small tricks!

After paying one or two hundred casualties and panic, Yang Ren finally rushed through the pile of trees with his henchmen, trying to chase down the Danyang soldiers who had already put away their bows and crossbows and retreated.

Hehe, with the humble fortifications to delay the cavalry, and want to leave after shooting arrows?

The anger in Yang Ren's heart against these Danyang soldiers was even more intense than the hatred of the French Knights for the Breton longbow dogs in the Battle of Agincourt.

But it's a pity that the Danyang soldiers are not longbow dogs, and Li Su's guards this time are not only Danyang soldiers.

Yang Ren climbed over the obstacle and could not stand on a stable footing, when he saw a majestic general with silver spears and white horses, who had already led five hundred cavalry to line up and wave their guns towards him.

"I am Yang Ren, the general of Hanzhong, and I will die!" Yang Ren was already provoked to be angry, and when he saw this, he immediately transferred all his anger to Zhao Yun, and stabbed the needle at Mai Mangdi, without the slightest fear.

This is not a heads-up, it is just a simple hedge of two cavalry generals leading their armies along the valley.

"Have these Hanzhong people been isolated from the world for a long time, and they don't know that there is a sky outside the outside world?" Zhao Yun couldn't help but wonder with pity in his heart for a second.

But he will not underestimate the enemy because of this, and the gun is still as solemn as ever, and he does not spare any hands.

"Puff~"

Yang Ren's neck blood soared, and his eyes were full of disbelief: hasty...... I forgot that I was exhausted after a night of travel, and if I had a good meal and a good night's sleep, I would definitely be able to block this shot......

Until it slowly darkened in front of him, Yang Ren still comforted himself like this in his heart, and then there was no more.

"Why is it so empty? Looking at the posture, I thought that I would try to block my shot, but I was actually killed when I touched it. Zhao Yundu was a little surprised, he looked at Yang Ren's moves, and thought that he could stab the opponent after three or five rounds.

No matter what, while Yang Ren was blocked by a shot, Zhao Yun turned over and rushed to kill, a silver spear was like fluttering snow, and dozens of people were killed in a mixed manner, and Yang Ren's personal army was instantly shattered, like a watermelon dropped on the balcony on the twentieth floor.

Zhao Yun thought to himself that he had fought for two or three years, and he had never encountered such a refreshing charge from cavalry to cavalry.

Those Zhang Lujun cavalry who ran all night and didn't sleep simply staggered as soon as they stabbed them.

"Run, General Yang was killed by that crazy general with one shot!"

The cavalry of Zhang Lu's army was covered by Zhao Yun and retreated five or six miles along the valley, leaving behind hundreds of corpses and many more wailing wounded. The combat strength of this group of cavalry has lost at least a small half.

"Don't rush in, hurry up and keep a distance from the Han envoys, camp and hold on, the enemy doesn't move, I don't move!" Quickly notify General Zhang to come for reinforcements! Seeing that Zhao Yun didn't chase after him, the surviving colonels under Yang Ren hurriedly restrained the troops to make adjustments.

As long as he bites Zhao Yun, Zhao Yun will not dare to march at full speed, and he will have to divide his energy to guard against them, so that he can buy time for Zhang Wei. 1603367562
