Gan Ning didn't know how many tricks Li Su used to play Dong Yue and Fan Chou on the frontal battlefield, so that they always felt that "if they work harder, victory is in sight", so they were reluctant to give up Yangpingguan.

Anyway, Gan Ning just took care of himself, and hurriedly took 10,000 Ban Yuman mountain troops, and arrived at the northern section of Ma Mingge Road three days later, seeing that there were only the last two mountain passes from Xiguan Station, and after Xiguan Station, it was Yangping Pass for forty miles.

This is the road that the mountain soldiers can reach in just a day's march. Moreover, because of the improvement of water transportation on the Jialing River, when Ganning's troops came, most of the roads could be taken by boat, so their physical strength was maintained well.

Coupled with the internal combat and defense, Gan Ning is also quite familiar with the terrain, and he estimates that if the enemy has reinforcements from the south, most of them will be stationed at Xiguanyi and send scouts to search. Therefore, he disembarked in advance and took the land route before he arrived at Xiguanyi, on the one hand, it was convenient to start a formation battle at any time, and on the other hand, he planned to take a short detour on the last journey.

On the Ma Ming Pavilion Road, it is not completely impossible to bypass Yangping Pass and enter the Hanzhong Basin - in the history of Liu Bei's attack on Cao Cao/Xiahou Yuan's battle in Hanzhong, Liu Bei was blocked in Yangping Pass, from the section south of the West Pass on Ma Ming Pavilion Road, suddenly went over the mountain and detoured, and took the Micang Mountain Road to reach the Dingjun Mountain behind Yangping Pass.

It's just that the use of this road is very risky, first of all, only the troops attacking from the south to the north can use this road, and the enemy attacking Hanzhong from the north to the south can hardly use it-

Because Micang Mountain is in the south of Yangping Pass, those who come from the north must first pass through the pass road, then go a long way to the south, and finally go around the north, in short, it is easy to be exposed, and it is easy to be cut off when winding. (In the battle of Hanzhong in history, Liu Bei fought from south to north, so he could take the path on Micang Mountain)

Moreover, this time the Hanzhong guard will have Li Su, Li Su has foresight, of course, he will not make the mistakes of Xiahou Yuan in history. Therefore, Li Su had long known that he would camp at the exit of the Micang Valley Road and near the side of Dingjun Mountain, even if Dong Yue and Fan Chouzhen went around, he would only be ambushed and annihilated in the path of Micang Mountain, and he would not be able to enter the Hanzhong Basin.

Fan Chou can't go around Micang Mountain, and even the main force of the Han army brought by Zhang Fei from Qianwei is also risky to go to Micang Mountain, and it is easy to fall to death.

But these difficulties do not exist in front of Gan Ning - strictly speaking, whether it is Dingjun Mountain or Micang Mountain, they are all part of the Daba Mountain Area, and Ban Yuman is the barbarian mountain hunter who has lived in the Daba Mountain Area for generations.

In the eyes of these soldiers who have the potential of "Wudang Flying Army", the most dangerous trail in Micang Mountain is also drilled casually and will never kill a person, which gives Gan Ning the opportunity to get in touch with Liu Bei and Li Su without being discovered by the enemy army in Xiguanyi.

There are still 70 or 80 miles of road along the valley of the Jialing River, and only 60 miles along the Micang Mountain through the mountains, and nearly 20 miles of savings. While Gan Ning was moving rapidly, he soon bumped into the scout left by Li Su, but fortunately he saw that Gan Ning's people looked like local barbarians, so the scout did not release arrows, but shouted joints.

"Who is coming! Stop! The right general will be ordered to defend here, and if we advance again, we will release the arrows! The caller was alert.

Gan Ning was slightly startled when he heard this, and then turned happy, and immediately asked the soldiers to unfold the military flag folded in the baggage - because the flag was too windy when climbing the mountain, it was easy to blow the flag bearer down and be in danger, so it was usually not unfolded.

After raising the banner, Gan Ning shouted loudly to present his identity, and after careful verification, the other party finally let them go through the mountain mouth in batches, and released the signal on the side.

Before Gan Ning walked out of the Micang Pass, he met Li Su with some blocked Tuntian soldiers to greet him, and Gan Ning hurriedly stepped forward to salute when he saw it, expressing his respectful listening to the military order.

Li Su shook the folding fan: "Counting the days, I also think that Captain Gandu should come, the lord ordered you to divide the army to contain it on the southern flank, delay the enemy army and wait for General Zhang's arrival." Choose a small number of elite soldiers, and those who can best climb the mountains and take risks will be of other use. ”

Then, he led Gan Ning and a small number of vanguard troops to Chuyang to meet Liu Bei.

After entering the city, Gan Ning's vanguard elite troops had a full meal first, and then Li Su explained the follow-up battle plan to Gan Ning in front of Liu Bei.

"It has been seven or eight days since Dong Yue and Fan Chou's troops attacked Yangping Pass in this battle, and our army has one or two thousand casualties, so we will not easily let Dong Yue and Fan Chou go back. My lord and I have been collecting local medicine farmers and hunters these days, and we have found a road that can reach the northwest of Yangping Pass, on both sides of the mountain road where the enemy army came. It's just that it's very dangerous and difficult to travel, and some sections of the road can only go down but not up, and they can't accommodate too many soldiers to set up ambushes.

Captain Gandu, the Ban Yu Man under your command is the strongest in our army, and you need to assign two or three thousand people to take on the heavy task of intercepting after this circumambulation. Don't worry that the enemy is too strong to stop - I will help you with eighty Yuan Rong crossbows in advance, and ambush you in the narrowest and most cramped part of the mountain road in advance. The crossbow was heavy, difficult to move, and had a short range that made it impossible to pursue, so it had to lie in ambush at the narrowest point of the valley. ”

Li Su said while Gan Ning looked at the map, Li Su said that the road over the mountain, of course, was not on the map, it was all up to him to point out at will, and a guide would definitely be sent at that time.

And the reason why this kind of road cannot be used by the besieging party, Li Su also made it very clear, because "you can go down but not up", when you go down from the mountain, you can slowly slide down the tree buffer, but it is impossible to climb up.

It can be compared to Gan Ning's walk on Mage Mountain and Fu Youde's walk on Motianling, both of which are rolled down from a steep slope by people wrapped in blankets, but it is absolutely impossible to climb back back after rolling down. Therefore, Li Su's choice of this path, the party tackling the key problems is not aware of its existence at all.

Gan Ning thought about it, because he was not sure about the enemy's situation, he was still a little worried, and couldn't help asking: "Since this road is so difficult to travel, and the mountain that can be ambushed is so narrow that it can't accommodate too many troops. But I don't know how many enemy troops are there in front of Yangping Pass now? ”

Li Su shook the folding fan: "According to our estimation for many days, there should be no less than 20,000 veterans of Xiliang brought by Dong Yue and Fan Chou, and there are also 10,000 or 20,000 people and peasant soldiers who temporarily captured Ding from the vicinity of Chencang City, with a total strength of 30,000 or 40,000. However, there have been many casualties in the onslaught for several days, and there should be a total of 30,000 people at present.

Therefore, you just want to block the rear now, plus show weakness head-on, maybe you can take the initiative to attack on the Ma Mingge Road and lose one or two small battles, so that the enemy thinks that the first batch of reinforcements of our army is weak and has the opportunity to be broken by each one, so many delays for five or six days, and when General Zhang comes, you will have a total of 20,000 soldiers and horses, and it is completely certain that you will swallow up the enemy's 30,000 tired divisions. ”

Gan Ning felt that there was no problem with the total timing and rhythm, but when he thought of the troops behind the mountains and slopes, he was a little uneasy: "Although our army has 20,000 at that time, it can be distributed very unevenly, and only 3,000 can break the road after the rear......

Li Su smiled at this time, and continued to point to the map to explain to Gan Ning: "Xingba doesn't have to worry too much, and look at the map - the enemy army of 30,000 is not gathered in one place at present, but in a herringbone shape coming from the side, scattered and deployed in the valley road in front of Yangping Pass.

From Yangping Pass, there are two roads that lead to the bank of the West Han River, one is the herringbone one, and it goes northwest to the bank of the West Han River, which is the way the enemy comes. The second is the way to the southwest, which is the way from Hanzhong to the Sword Pavilion, which is the way you and General Zhang will come for reinforcements.

And from Xiguanyi directly to the north, along the bank of the West Han River, you can also reach the northwest road of Chencang Road and retreat to the direction of Hechi County. So it's a triangular road. I asked you to divide the army of 3,000, but to block the 'retreat from Yangping Pass directly to the northwest to the shore of the Western Han River', and the bottom of the triangle is to let out.

After the enemy army is blocked, it can actually try to take a detour to Xiguanyi first, and then retreat along the north side of the river. So as long as your 3,000 men are strong enough and the initial blow is enough to scare the enemy, so that the enemy army does not know the truth. Then there is still a chance that they will choose to take another detour instead of directly following you.

It's just that when they want to go around Xiguanyi, they will find that Yide is already storming Xiguanyi, and at this time they have to choose whether to block Yide's attack in Xiguanyi and buy enough time for the follow-up friendly troops to escape around this road. It's better to run first and make sure that you can survive, regardless of the life or death of the friendly troops who have not had time to withdraw from the forty-mile mountain road from the Yangping Pass Wall to the Xiguan Station...... I think that with the brutality of the Xiliang army and the large number of peasants who forcibly forced Latin Latin, Dong Yue Fan Chou will definitely not be able to control the troops at that time. ”

After listening to Li Su's deployment, Gan Ning couldn't help but gasp.

This is a deformed version of the "three missing one" in the siege war, and it has been taken to the extreme! It's just that this circumference is not aimed at the city wall, but a triangle composed of three forty-mile-long mountain roads. First cut off one side and force you to go to the other two, and then stop the ......

When Li Su himself was making this deployment, he actually remembered an RTS strategy game he had played in his previous life, called "Fortress".

In "Fortress", the best way to kill and injure the largest number of enemy soldiers is to use the crossbowmen who are ambushed on the city walls on both sides, and the best way is not to completely seal the city walls and city gates, but to build nine bends and eighteen bends, and the city gates are empty, but the city gates are built inside the urn city and the labyrinth......

It's a bit like a tower defense game, so that the enemy travels as far as possible on the way up and is covered by fire for as long as possible.

……

After Gan Ning got the order, he quickly went to deploy according to the plan. First of all, he left about half of the Ban Yu Man, stopped the act of crossing the Micang Mountain and circumambulating the Guannai, but continued to stay in the Ma Ming Pavilion Road, more than 20 miles away from the Xiguan Station, and set up camp.

In this way, first, it can show weakness, so that after the scouts of the Xiliang Army find out, it is confirmed that there are not many reinforcements in the first batch. Second, it can also protect the secret that "there is a path into the Hanzhong Basin on Micang Mountain", it seems that Gan Ning is blocked because of the Xiguan Station, and it is impossible to meet Liu Bei and Li Su, pretending that "if you want to meet, you have to enter the customs, and you can only take the road of Yangping Pass".

After the arrangement, Gan Ning knew that there was not enough time that day, and the enemy would not come to attack the Ban Yu Man who stayed in Ma Ming Pavilion Road, and if the enemy army came to attack tomorrow, then he would withdraw directly and run to the Micang Mountain Mountain in the east. If the enemy retreats, then go down the mountain and assemble again. On the third day, if you pretend to try to sneak into the customs and then try to retreat, won't you lure the enemy to delay enough time until Zhang Fei comes?

As for Gan Ning himself, after making this deployment, he took 3,000 elites who were the most capable of climbing the mountain, and carried eighty Zhuge crossbows with difficulty in advance to the mountain road ambush point in the northwest of Yangping Pass - these eighty crossbows were the products produced overnight in the past ten days by the Hanzhong Army Workshop, and the production capacity was only so large. Because of the difficulty of transportation, it is necessary to go to the ambush point a few days in advance to preset the position.

As for the five days before Zhang Fei came, the Nanzheng workshop could theoretically create twenty or thirty more Zhuge crossbows, but these would not have time to be deployed to the ambush point, and then it would be better to stay on the wall of Yangping Pass to fight a defensive battle - didn't Gan Ning leave 5,000 people in Ma Mingge Road and 3,000 people in the Northwest Mountain Road.

In the end, Gan Ning also exerted his subjective initiative and persuaded the last 2,000 banbans to be left as the defenders of the Yangping Pass Wall, and when the final general attack was really launched, Li Su could open the gate and pretend to cover up and cooperate with the battle from the inside out.

And because the Xiliang Army saw the long-lost Yangping Pass, it actually opened the door at the last moment, maybe it would be even more chaotic and even more uneven because it couldn't withstand the temptation and wanted to rush to the gate.

If there are 2,000 barbarians blocking the gate, it can ensure that the enemy will not break through the gate, and at the same time, it can also give the last twenty or thirty Zhuge crossbows on the wall a chance to exert their firepower.

At that time, it was the three-way attack of the troops after Gan Ning's break, the reinforcements of the Pegasus Mingge Road, and the Ban Yuman, which was killed in the gate, and the three sides of the enemy's triangular marching route were accurately detonated in turn.

With such a big battle, it is not over without shooting a single rebel general.

After Liu Bei and Li Su listened to Gan Ning's last suggestion, they also praised it, and Liu Bei personally rewarded him: "I didn't expect that although Xingba has little reading, he has a lot of tactics for changing in battle, and he will also have the talent of a general in the future." ”

Li Su was relatively cautious: "However, when the time comes, if you want to mess with the enemy's target at the last moment, you must open the gate to lure the enemy, which is still more dangerous, you need to block the door fiercely, otherwise it is easy to be self-defeating, Xingba wants to go to Beishan to set up an ambush, and then you have to take the lead, and Yide will take the lead in Xiguanyi." The weight of this door...... Let's take a look at Dian Wei and Xu Huang first, and whether they can take on this heavy responsibility. ”

Liu Bei nodded again and again: "This is a serious opinion, and it should be so." ”

After the meeting ended, Li Su brought some meat and supplements and went to Dian Wei's residence to visit the sick, after all, Dian Wei was also hit by two arrows and suffered some other injuries when he protected Liu Bei's retreat from Wuzhangyuan a month ago.

Dian Wei saw the boss coming, and immediately went out to greet him.

Li Su didn't talk nonsense: "This time I came to see if you were injured, five days later, the reinforcements of Yide and Xingba will all be in place, and at that time, in order to lure the enemy into annihilation, you may have to open and close the door to cover up - let you and Gongming bring two thousand banban, block the gate after opening, and there will be crossbows at the head of the city to cover you and shoot the enemy troops who rush up." Can you still fight with your injuries? ”

"Do you need to talk about that?" Dian Wei picked up a scrapped old iron halberd, inserted it directly into the tethered stone at the gate of the courtyard, picked up the stone and waved it half a circle.

"Stop, stop! Okay, when the time comes, work hard, and if you win, you will be given an additional 500 stones. ”
