The Han army erected ten well fences, ten catapults, and a hundred sunset crossbows, and launched an attack on Jiameng Pass.

First, through the catapult, the fire meteor was projected on the close, and the fire meteor was filled with gunpowder and iron pellets, and when it fell, it exploded, and the explosion was extremely violent.

Supplemented by the Sunset Crossbow, it keeps firing fiery arrows. This flaming arrow is also bound with gunpowder iron pills.

The range of siege equipment is much more than that of ordinary bows and arrows, so the Shu army on Jiameng Pass can only watch the Han army launch fire meteors and fire arrows, and the dry staring, the bows and arrows in their hands can't shoot the Han army at all.

At the same time, it is necessary to accept the grave fact that there are many casualties.

After a wild bombardment, in less than half an hour, Jiamengguan had been blown into ruins.

The well bar began to push forward.

Due to the progress of Luoyang's casting and forging process, as well as the continuous mining of iron ore and the continuous expansion of the casting and forging workshop, the combat attributes and usability of the well bar have also been greatly improved, and it has been improved from the original three layers to the current two.

The bottom layer is the body of the car, which is used for walking, and inside can be soldiers or livestock, which is used to push the movement of the well fence.

The upper floor is the battle part, and there are soldiers inside, who shoot out with bows and arrows.

Moreover, the current well fence is wrapped with iron sheet from top to bottom, and holes are opened in the iron sheet for observation and archery, which is light and strong, and can defend against the attack of ordinary arrows.

And in this era, only Luoyang has this kind of process for producing iron sheets.

Therefore, the Han army has used the well bar technology to the extreme, and in appearance, it is simply a primitive "manpower tank".

However, it was said that after the city wall was blown down by catapults and sunset crossbows, the well fence was pushed forward, and the horse shot rushed forward, and it didn't take long to rush to the Jiameng Pass.

I saw that the ruins were full of corpses of the Shu army, as well as Shu soldiers who knelt on the ground and surrendered.

Liu Xie ordered that those who surrendered were not guilty and should not be killed! In addition, to track Zhang Ren's whereabouts, a Shu army reported that Zhang Ren led a thousand troops to escape from Jiameng Pass and fled in the direction of the Sword Pavilion in front.

Liu Xie ordered the cavalry to advance quickly, to the Sword Pavilion, and the baggage logistics and engineering troops swept the tail behind, disassembled and loaded all the siege equipment, and slowly came behind.

There are only more than 10,000 defenders of the Shu army in Jiameng Pass, because the pass is dangerous, so there is no need for many people to guard, who can know that the Han army is powerful, and it will not take long to break through the pass.

The Sword Pavilion is the fastest way to enter Shu in Hanzhong, the mountain road is steep, and there is basically no road to go. There was originally a plank road on the Sword Pavilion that could accommodate sergeants to pass through, but when Zhang Ren fled back, the plank road was demolished.

When the cavalry of the Han army came to the Sword Pavilion Qian, they saw the mountains and mountains in front of them, and there was a slender canyon in them, which could only accommodate one person and one horse to pass side by side.

Liu Xie called Zhuge Liang and his wife over and asked, "Kong Ming, Yueying, it's getting late, you two look, how should we get over?" ”

Zhuge Liang looked around and said, "Your Majesty has been in Hanzhong for four months, right?" There was no conquest for four months, and Wechen guessed that Liu Zhang had four months to prepare, so Wechen thought that there must be an ambush in this Sword Pavilion. The ambush and the steep road, even if we have a strong weapon, it will be difficult for us to pass. ”

After Zhuge Liang finished speaking, he pointed to the canyon and said: "Our 400,000 army, this road is narrow and long, and it can only accommodate one person to ride through, even if there is no ambush, it will take a long time to complete." ”

Liu Xie asked: "Then according to the military division, there is no strategy to pass?" ”

Zhuge Liang said: "There are strategies, but they are a bit hard. ”

"But come on."

Zhuge Liang pointed to the mountain and said, "Go over the past." ”

Liu Xie rode on the horse, looked up, and couldn't help but gasp: "This is very difficult." ”

Zhuge Liang said: "Otherwise, you can go by detour, but it will take at least a month." ”

"A month? That's absolutely not good, the grain and grass can't keep up. Liu Xie said, "We must rush to Fucheng as soon as possible." Summoning the order to go down, prepare the rope, and prepare to climb over the Sword Pavilion. Let's set up camp first. ”

Liu Xie only brought 100,000 cavalry to come first, and after giving the order, he immediately set up camp and convened the generals to discuss. Looking at the map, Liu Xie fell into a deep groan, the Sword Pavilion is actually a very vast place, but if you want to go to Fucheng, you can only go through the mountains in front of you, otherwise, as Zhuge Liang said, you can only take a detour.

And the steep mountain to be crossed, its straight-line distance is not long, after the past there will be a large section of smooth road, can quickly reach Fucheng.

Zhuge Liang said: "Your Majesty, Weichen looks at the sky, there is heavy rain tonight. ”

"Heavy rain?" Liu Xie turned to look at Zhuge Liang, and at the same time, the small dictionary in his brain also said: "Yes, master, there is heavy rain tonight, and there is heavy rain when the sky is almost dawn." ”

"Yes, Your Majesty," Zhuge Liang said: "If Weichen is not mistaken, it should be the second half of the night, and there will be intermittent rain tomorrow, this is the first heavy rain in Shu since the beginning of spring." ”

Liu Xie began to walk back and forth in the hall, thinking.

"Your Majesty......" Zhuge Liang said softly.

"Yes."

Zhuge Liang walked to the map, and there were two maps hanging in the hall, one was drawn by Liu Xie, and the other was drawn by Zhang Song. Zhuge Liang looked at it carefully and said, "Weichen thought that this rain was very timely. ”

"Oh, let's hear it."

Zhuge Liang pointed to the map and said: "Your Majesty, you see, it is very easy to set up ambushes on both sides of the canyon, and we go about ten miles to this side, you see, this is this place, it is the best place to climb." Climb to the top of the mountain, and then go to the edge of the canyon and launch a surprise attack on the enemy ambush, then ......"

Liu Xie took over and said, "Even if the canyon is opened? ”

Zhuge Liang said: "Yes, Your Majesty." And on rainy days, the enemy is prone to slackening, and we also launched a surprise attack. ”

Liu Xie smiled and said: "What a praying mantis catching cicadas and yellow finches are behind." ”

He called Zhang Song over again and asked, "How many garrisons are there in the Sword Pavilion?" ”

Zhang Song said: "The Sword Pavilion is too remote, so there are not many garrisons, at most three thousand. ”

Liu Xie said: "One husband should be closed, and three thousand is enough for us." ”

Liu Xie looked at the map carefully, pointed to another place and asked Zhang Song: "Can this place be climbed?" ”

Zhang Song also looked at it carefully and said, "Yes." ”

Liu Xie looked at the map and thought for a while, and said to the generals: "The generals will listen to the order!" Xu Chu, Xu Huang! ”

"Wechen is here."

"Xu Chu, you lead a thousand troops with firearms and ropes, climb over the upper ridge from here overnight, go to the top of the canyon and ambush here, and wait for the heavy rain to pour tomorrow morning to launch a surprise attack on the enemy troops on the ridge!"

"Weichen Command!"

"Zhang Song, how are you doing?" Liu Xie asked.

Zhang Song knew what he meant, so he said; "It's no problem for Weichen to climb over the steep."

"Okay, you are the guide officer, and you will climb with Xu Chu. Xu Huang ......"

"Wechen is here."

"You follow me and lead a thousand troops to climb here!"
