Gan Ning didn't know how many tricks Li Su used to play Dong Yue and Fan Chou on the front battlefield, which made them feel that "if you work harder, you will be in sight", and he was reluctant to give up Yangping Pass.

Anyway, Gan Ning just took care of himself, so he quickly took the 10,000 Banguanman Mountain troops and arrived at the northern section of Mamingge Road three days later. He saw that there were only two valleys from Xiguan Post, and after passing Xiguan Post, he walked forty miles to Yangping Pass.

This road can be reached in just one day by mountain soldiers. Moreover, due to the improvement of the water transportation of the Jialing River, Ganning's troops could take boats on most sections of the road, so their physical strength was maintained.

In addition to fighting in the interior and defending, Gan Ning is also familiar with the terrain. He guessed that if the enemy was prepared for reinforcements from the south, he would probably be stationed in Xiguan Post and sent scouts to search. So he got off the ship in advance before he arrived at Xiguan Post. On the one hand, it was convenient for formation battles at any time, and on the other hand, he planned to take a shortcut in the last journey.

On Mamingge Road, there is not a short mountain road that can directly bypass Yangping Pass and enter the Hanzhong Basin. In history, when Liu Bei attacked Cao Cao/Xiahou Yuan in Hanzhong, Liu Bei was blocked after Yangping Pass, and suddenly crossed the mountain and took the Micang Mountain Road to reach Dingjun Mountain behind Yangping Pass after being blocked.

However, this road is very dangerous. First of all, only troops attacking from south to north can use this road, while the enemy attacking Hanzhong from north to south can hardly be used--

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

Moreover, this time, Li Suzai, the Hanzhong general, was in advance. Of course, he would not make the mistakes of Xiahou Yuan in history. So Li Su had long known that he had camped and defended at the exit of the Micang Valley Road near the side of Dingjun Mountain. Even if Dong Yue and Fan Chou were really around, he would only be ambushed and wiped out in the small road of Micang Mountain and could not enter the Hanzhong Basin.

Fan Chou could not surround Micang Mountain, and even Zhang Fei brought the main force of the Han army to Micang Mountain from Jianwei, there was a risk of falling and killing people.

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 Mountains, and Banyan Man is a barbarian mountain hunter who has lived in the Daba Mountains for generations.

In the eyes of these soldiers with the potential of "Not-dang Flying Army", the most dangerous and remote path in Micang Mountain is that they will never fall to death by just drilling. This gives Gan Ningshen the enemy troops in Xiguan Post without knowing it, and the opportunity to contact Liu Bei and Li Su.

There are still seventy or eighty miles of road along the Jialing River Valley, and only sixty miles of roads along the Micang Mountain, saving nearly twenty miles. While Gan Ning was moving forward rapidly, he quickly bumped into the scout left by Li Su. Fortunately, he saw Gan Ning's people like local barbarians, so the scout did not shoot arrows, but called for a call.

"Who will come! Stop quickly! Under the orders of the Right General, we will shoot arrows when we advance again!" The person who called was very alert.

Gan Ning was slightly surprised when he heard this, and then he became happy. He immediately asked the soldiers to spread the military flags folded in his bags. Because the flag was too windy when climbing the mountain, it was easy to blow the flag holders down and get into danger, so they did not spread them normally.

After tying up the banner, Gan Ning shouted loudly to present his identity. After the other party carefully verified, he finally let them go in batches and sent signals.

Before Gan Ning could walk out of the Micang Pass, he met Li Su and some military soldiers who were blocking the entrance to greet him. When Gan Ning saw this, he hurried forward to salute and expressed his respect for the military order.

Li Su shook the folding fan: "I think it's time to calculate the days and think that the commander Gan Du is coming. The lord ordered you to divide the troops into a group of troops to restrain them on the southern wing, and delay the enemy's arrival. Choose a small number of elite troops, which is the best way to cross the mountains and go on dangerous situations, which is of other use."

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

After entering the city, Gan Ning's elite troops had a full meal first, and then Li Su explained the follow-up combat 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. Our army suffered one or two thousand casualties, so we will not let Dong Yue and Fan Chou go back easily. These days, my lord and I recruited local medicinal farmers and hunters to find a way to reach the northwest of Yangping Pass, on both sides of the mountain road where the enemy came. It was just very dangerous and difficult to walk, and some sections of the road could only go down but not up, and they could not accommodate too many soldiers to set up ambush.

Guard Gan, your Banyan Man is the strongest person in our army to cross the mountain. You need to split two or three thousand people to take on the heavy responsibility of interception. Don’t worry that the enemy is too strong to stop it - I will help you in advance eighty Yuanrong crossbows, ambushing in the narrowest and narrowest part of the mountain road in advance. This crossbow is heavy, not easy to move, and has a short range, so it cannot be pursued, so it can only be ambushed in the narrowest part of the valley."

While Li Su was talking, Gan Ning looked at the map. Li Su talked about the road to climbing mountains. Of course, there was no road on the map. He only relied on his random guidance. He would definitely send a guide at that time.

Li Su also made it clear that this kind of road cannot be used by the siege, because it is "can go down but not up". When you go down from the mountain, you can slowly slide down along the cushion of trees, but it is impossible to climb up.

It can be compared to Ganning's walking on Mage Mountain and Fu Youde walking on Motianling. People rolled down from a steep slope with blankets, but it is absolutely impossible to roll down and climb back. Therefore, the researcher of Li Suxuan's road was not aware of its existence.

Gan Ning thought about it, but because he was not sure about the enemy situation, he was still a little worried and couldn't help asking: "Since this road is so difficult to move, the hill that can be set up is so narrow and cannot accommodate too many troops. But I wonder how many enemy troops there are in front of Yangping Pass now?"

Li Su shook the folding fan: "According to our estimates over the past few days, Dong Yue and Fan Chou should have no less than 20,000 veterans from Xiliang. They temporarily arrested Ding from the surrounding area of ​​Chencang City, and there were also 10,000 or 20,000 peasant soldiers, with a total force of 30,000 to 40,000. However, there were many casualties in the attacks in recent days, and there should be only 30,000 in total.

So, now you just want to block the back, and show weakness on the front, maybe you can take the initiative to attack on the Maming Pavilion Road and lose one or two games, making the enemy think that our first batch of reinforcements are weak and have the chance to be defeated by each one. If so, so many days are delayed, when General Zhang comes, you will have 20,000 troops in total, and it is completely certain to swallow the enemy's 30,000 tired army."

Gan Ning felt that the total timing and rhythm were fine, but when he thought of the troops who were rolling over the mountains and rolling around the slopes, he was a little worried: "Although our army has 20,000, the distribution is extremely uneven, and only 3,000 people can break the road. If the 30,000 people become a fight of beasts and fight to break through the road, I am afraid that the three thousand Banhuanman will be wiped out and will not be blocked..."

Li Su then smiled and continued to point to the map to explain to Gan Ning: "Don't worry too much about Xingba, let's look at the picture - the enemy troops are 30,000, but are not gathered together at the same time, but are in a side-shaped herringbone shape, deployed scatteredly in the valley front road in Yangping Pass.

From Yangping Pass, there are two roads that lead to the bank of the Western Han River. One is the one with a herringbone. It goes northwest to reach the bank of the Western Han River. That is the enemy's way. The second is the one with a southwest, which is the way to Jiange from Hanzhong, which is the way to reinforce you and General Zhang.

From Xiguan Post directly to the north and along the banks of the Western Han River, you can also reach the northwest route of Chencang Road and retreat to the direction of Hechi County. So this is a triangular route. I asked you to divide your troops into three thousand, but just block the stroke of "retreat directly to the northwest route from Yangping Pass to the bank of the Western Han River", and the stroke and the bottom edge of the triangle are given out.

After the enemy is blocked, you can actually try to take a detour to Xiguan Post and retreat along Hebei. So as long as your 3,000 people are strong enough, the initial strike is enough to scare the enemy and make the enemy unaware of the reality. Then they still have the chance to choose another detour instead of just carrying it with you.

However, when they wanted to circumnavigate, they would find that Yide was already attacking Xiguan Post. At this time, they had to choose whether to circumnavigate the attack of Yide at Xiguan Post and gain enough time for the subsequent friendly troops to escape on this road. It would be better to run first to ensure that they could survive. Regardless of the lives and death of friendly troops who had not had time to withdraw from the forty-mile mountain road under the Yangpingguan Wall to Xiguan Post... I think that with the brutality of the Xiliang Army and the large number of farmers who forced Latin, Dong Yue and Fan Chou would definitely not be able to control the troops by then."

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

This is a deformation version of the "three circumferences and one" in the siege battle, which has been brought to the extreme! However, this three circumferences and one circumferences are not aimed at the city wall, but a triangle formed by three forty-mile-long mountain roads. First cut off one side and force you to walk the other two sides, and then cut in half...

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

In "Fortress", the best way to use crossbowmen ambushing the walls on both sides to kill the largest number of enemy soldiers is not to completely seal the city walls and gates, but to make the city gates bends and bends, and the city gates are empty, but to repair the city walls and mazes inside the city gates...

It's a bit like a tower defense game, which requires the enemy to pass as far as possible on the way up and the time it is covered by firepower should be as long as possible.

...

After Gan Ning got the order, he quickly went to make arrangements according to the plan. First, he kept about half of Banyan Man and stopped climbing over Micang Mountain to the inner gate. Instead, he continued to stay in Maming Pavilion Road and camped more than 20 miles away from Xiguan Post.

In this way, one can show weakness, and after the scouts of the Xiliang Army discovered it, they confirmed that there were not many reinforcements in the first batch. Secondly, they can also protect the secret of "there is a small road entering the Hanzhong Basin on Micang Mountain". It seems that Gan Ning is blocked from Xiguan Post and it is impossible for him to meet with Liu Bei and Li Su, pretending that "If you want to meet, you have to enter the pass, you can only walk the road of Yangpingguan closure."

After the arrangement was made, Gan Ning knew that the time was not enough that day, and the enemy would not attack the Banyan Man who stayed in Maming Pavilion. If the enemy attacked tomorrow, then retreat directly and run to the Micang Mountain Mountain area in the east. As long as you go up the mountain, the terrain of Liang soldiers in the west would definitely not be able to catch up with Banyan Man. If the enemy retreated, then go down the mountain to gather. On the third day, pretend to try to smuggle and sneak into the pass, and then try to retreat again. Wouldn't it be tempting the enemy to drag the time to wait until Zhang Fei comes?

As for Gan Ning himself, after making this arrangement, he took 3,000 elite elites who could cross the mountains and carried eighty Zhuge crossbows in advance and went to the ambushing point in the northwest of Yangpingguan - these eighty crossbows were produced overnight by the Hanzhong Army Workshop over the past ten days, and the production capacity was only so large. Because of the difficulty of transportation, it was necessary to set up ambushing points at high places a few days in advance to preset positions.

As for the five days before Zhang Fei came, Nanzheng Workshop could theoretically create twenty or thirty Zhuge crossbows, but these were not too late to deploy to the ambush point. Then, you can stay near the wall of Yangpingguanguan to fight defensive battles - Didn’t Gan Ning leave five thousand at Mamingge Road and three thousand people at the ambush point of Northwest Mountain Road?

Gan Ning finally exerted his subjective initiative and persuaded him to stay for the last two thousand bans, and he would serve as the defender of Yangpingguan Wall. When he really launched the general attack, Li Su could open the door and pretend to be in a close combat from the inside out to cooperate.

The Xiliang Army saw that Yangping Pass, which had been unsuccessful for a long time, opened the door at the last moment. Maybe it would be even more chaotic and even more uneven in the military's morale because it could not withstand the temptation and wanted to rush to the door and grab the pass.

If there are two thousand bans blocking the door, it can ensure that the enemy will not break through the door. At the same time, it will also give the last twenty or thirty Zhuge crossbows on the wall to exert their firepower.

At that time, the Ganning army cut off the rear, Zhang Feima Mingge Road reinforcements, and Banman attacked from the gate, and accurately detonated the three sides of the enemy's triangular marching route in turn.

With such a big battle, it is not enough not to shoot a rebel general.

After listening to Gan Ning's last suggestion, Liu Bei and Li Su also praised him very much. Liu Bei personally commended him: "I didn't expect that although Xingba studied less, he had many strategies to change his skills in the face of the battle, and there will be talents of generals in the future."

Li Su was relatively cautious: "However, if you want to disrupt the enemy's target at the last moment, you must open the door and lure the enemy. This is still relatively dangerous. The fierce generals need to block the door, otherwise it will be easy to backfire. Xingba wants to set up an ambush in Beishan, and he must lead the way at that time. Yide will personally lead the attack at Xiguan Post. The important task of blocking the door... Let's first see how Dian Wei and Xuhuang and the others are injured, and whether they can take on this important task."

Liu Bei nodded repeatedly: "This is the case with this emphasis."

After the meeting, Li Su brought some meat and supplements to Dianwei's residence to visit him. After all, Dianwei was also hit by two arrows when he was evacuating from Wuzhangyuan a month ago and suffered some other injuries.

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

Li Su didn't say nonsense: "This time we came to see if your injury has healed. Five days later, all the reinforcements of Yide and Xingba will be in place. In order to lure the enemy to annihilate it, you may have to open and close the door to cover the killing - let you and Gongming lead two thousand barbarians to block the door after opening, and there will be a crossbow on the top of the city to cover you and shoot the enemy who rushed up. Can you still fight your injuries?"

"Is this a matter of saying?" Dian Wei picked up an old scrapped iron halberd and inserted it directly into the horse-tie stone at the entrance of the courtyard. He lifted the stone and swung it half a circle.
