In the next few days, the Jin soldiers did not launch an offensive, Wan Yan Chang wrote a letter to Wan Yan Xian also urgently asked for help, asking for support for heavy siege weapons, at the same time, Wan Yan Chang ordered the garrisons of the southern states of Hedong Road to rush to Taiyuan Mansion to participate in the war, the garrisons of the southern states of Hedong Road were mainly Han troops, numbering about 15,000 people, of which 5,000 were stationed in Jiexiu County to defend the logistics area, and the remaining 10,000 people were mainly responsible for exterminating the civilian anti-Jin troops and maintaining local order.

Although Wan Yanchang also knew that there would be hidden dangers in vacating the local army, he didn't have to think too much about it now, his task was to attack Taiyuan Mansion, and the matter of maintaining local stability was still left to Wan Yan Xian to consider.

After the fiasco of the storming of Taiyuan City, Wan Yanchang also temporarily gave up the crowd-style attack method, and began to use alternative siege methods, using strategy and ingenuity to attack the city, the Song army's earth-shaking thunder was powerful, which left a deep impression on him, and he also had three hundred Song Dynasty's earth-shaking thunder in his hands, which could play a role.

Wan Yanchang, like other Jin generals, hated the earth-shaking thunder made by the Jin State and abandoned it, on the contrary, they all liked the sky-shaking thunder of the Song Dynasty, which was practical, stable, and powerful.

At night, dozens of Jin soldiers under the cover of night, quietly approached the direction of the north city, when the gold soldiers seized the city of Taiyuan, they used a sneak attack at night, and blew up the north gate of Taiyuan with earth-shattering thunder, and the gold soldiers entered the city successfully.

Now, Wan Yanchang wants to repeat the old trick again, although the four main gates of Taiyuan are urn cities, but the city still has a weakness, that is, the water gate of Taiyuan.

Almost all big cities will have water gates, which is convenient for transportation and bulk material transportation, Taiyuan City is no exception, Taiyuan's water gate is located in the northwest corner of the city, and there is a Cao River with Fenshui in the west, because of winter, the river water has been frozen, and the water gate has temporarily stopped using.

But the water gate is a shortcut into Taiyuan City, there is no urn city inside, only two wrist-thick iron gates, the city gate is eight feet high, if the two iron gates are blown up, even the cavalry can kill into the city.

This plan was proposed by Liu Yanzong, the commander of the Han army, and was unanimously supported by the generals, and no one wanted their troops to suffer any more losses in the siege battle.

The specific implementation plan was twenty Han soldiers, they were strong in martial arts, agile in their movements, and two miles away, 5,000 Jurchen cavalry were ready, just waiting for the explosion to sound and kill at the city gate.

Twenty soldiers moved quickly, one moment bending and running, the other prostrate on the ground, getting closer and closer to the wall.

At the head of the city, the Song army was very vigilant, there were a thousand soldiers patrolling the north city, they were divided into ten teams, patrolling close to the city wall, and hundreds of soldiers stood on each battlement, monitoring any movement outside the city.

Yang Wenyi, the commander of the general on duty tonight at the head of Beicheng, was Liu Qian's subordinate, at this time, he hurried to the northwest corner of Beicheng, and several soldiers pointed not far away and said: "I saw a figure running below just now!" ”

"Did you all see that?" Yang Wenyi asked.

Several soldiers nodded, "We all saw it, there were about a dozen to twenty or so, and they were all lying on the ground and not moving. ”

Yang Wenyi immediately realized that there might be an enemy situation, and on the one hand, he sent soldiers to inform Liu Qian, and at the same time urgently dispatched 1,000 soldiers to Beicheng to support.

The twenty golden soldiers under the city also found that there were soldiers gathered at the head of the city to observe below, they suddenly felt bad, so they had to lie on the ground, not daring to run forward, and then walking forward entered the range of the Song army's divine arm crossbow, and they did not dare to expose their figures before they were sure of it.

At this time, Liu Jian also hurried to the northwest corner of the north city, in fact, he heard that an abnormality was found in the northwest corner, so he immediately guessed that the goal of the Jin soldiers must be to run towards the water gate, wanting to blow up the water gate and kill into the city.

Yang Wenyi pointed to the distance and said, "There seems to be an ambush two miles away, and the brothers heard the neighing of war horses. ”

Liu Jian looked into the distance, only to see a faint black shadow shaking in the distance, and there was indeed an ambush.

"Have you reported to the capital?" Liu Jian asked.

"Someone has been sent to report back."

Liu Jian thought for a while and said, "Don't startle the snake first, and then decide when the unification comes." ”

Not long after, Li Yanqing also rushed to hear the news, and Liu Jian stepped forward and whispered to Li Yanqing to report the soldier's discovery, and said: "Obviously, the other party wants to repeat the old trick, blow up the water gate, and open the passage into the city." ”

Li Yanqing pondered for a moment and said, "Could it be that the sound is attacking the west?" The target is somewhere else. ”

"It's unlikely, that would expose their intentions, but since they are all worried, they can strengthen their vigilance everywhere."

Li Yanqing nodded, "The first is to strengthen the vigilance, and the second is to block the possibility of them coming in through the water gate, is there any way to add the third gate?" ”

Liu Jian thought for a while and said: "It's best to use a boulder to block the door, but the boulder won't be ready until tomorrow at the earliest. ”

Li Yanqing said with a smile: "You can prepare the giant ice cube first, but don't rush to seal the door, wait for the first explosion of the Jin soldiers before sealing the door." ”

Liu Jian suddenly woke up, "Do you want to plan everything?" ”

Li Yanqing sneered: "Since they can't remember the lesson, I'll let their lesson be a little deeper." ”

.........

The soldiers lying on the ground under the city lay on their stomachs for half an hour, and their bodies were about to freeze, and the defenders at the head of the city gradually dispersed, so that the twenty soldiers breathed a long sigh of relief.

"Boss, do you want to move on?" Several soldiers asked.

The leader Jin Bing glanced at the cavalry behind him and said to one of his subordinates: "You go back and ask, see if you want to continue?" ”

The soldier slowly withdrew and retreated, and after a while, the soldier who went back to report the news came back, lay on the ground and said to the leader: "General Alihu reprimanded us for being cowardly and useless, delaying too much time, he asked us to go to the water gate first, if the Song army is not abnormal, then light the detonation thunder, if we are discovered, then give up the action, and warn us that we are not allowed to give up the action without authorization, otherwise we will be beheaded!" ”

The leader is a little embarrassed, what does it mean that there is no abnormality? Just now I found that there was an abnormality before I went to report it, to be honest, Jin Bing was still unwilling to give up, and he actually suspected that he had lied about the military situation, he secretly gritted his teeth and said: "Then let's go!" ”

Twenty soldiers got up again and rushed towards the water gate, this time they were not discovered by the Song army, almost rushed to the city in one breath, leaning against the city wall, twenty golden soldiers brought a total of three earth-shaking thunders, one inside and one outside the iron gate, and the other was a spare.

It was relatively easy to blow up the water gate, Jin Bing brought a cloth bag, first tied it to the iron fence, and then put the earth-shaking thunder in the cloth bag, from beginning to end, there was no abnormality.

At this time, the ignition gold soldier glanced at the leader, as long as the fire was lit, there was no room for repentance.

The leader looked around carefully for a moment, and after making sure that there was nothing abnormal, he nodded, and the ignition soldier shook off the fire fold and lit the fire rope that shook the sky, and the twenty men ran to both sides, and ran dozens of steps before lying on the ground, they couldn't run far, and they had to blow up the iron gate inside.

In just a moment, the earth-shattering thunder exploded, and the city wall shook with it, and a thick cloud of smoke rose into the air, mixed with a large amount of ice chips, and the explosion was so strong that almost the entire iron gate was broken off and flew out more than ten zhang away.

The sound of the explosion was the signal, and Ali, the commander of the golden soldiers in the distance, suddenly shouted, "Kill!" ”

"Kill!"

The five thousand Jurchen cavalry suddenly launched, the five thousand cavalry rushed like a tide, overwhelmingly killed, and the one thousand Wanyan Guards cavalry took the lead, killing a sharp spear to the northwest water gate of Taiyuan City.

According to the plan, when the Jurchen cavalry rushed a mile away, the second explosion should have exploded, and at this time, another violent explosion was heard in the direction of the water gate.

Ali suddenly rejoiced in his heart, the water gate must have been blown open, and he hissed and shouted, "Kill into Taiyuan City!" ”

In front of the water gate, the corpses of twenty Jin Guohan soldiers were everywhere, and the second earth-shaking thunder explosion was not caused by them, it was the city head that threw down a sky-shaking thunder, which happened to fall between them and them, and before they could react, it exploded in an instant, killing all twenty soldiers, and their bodies were torn apart by shock waves and shrapnel, and the death was extremely tragic.

At this time, the Song army in the city was quickly carrying a large ice block, a huge ice block was transported from the ice cellar, in fact, it had already been prepared, and it had been placed next to the water gate, when the second earth-shattering thunder exploded, the Song army immediately stuffed the huge ice block into the city cave, and then closed an iron gate inside.

Just as the iron gate was closed, five thousand cavalry had already killed one hundred and fifty steps away from the city wall, at this moment the long arm on the head of the city waved out, dozens of earth-shaking thunder flew up from the city, flying to the top of the cavalry group, dozens of earth-shaking thunder on the top of the cavalry a series of explosions, quenched iron pieces in all directions densely burst out, the huge explosion frightened the war horses, the cavalry turned over on their backs, countless.

At the same time, a dense number of soldiers appeared on the head of the city, raising their crossbows and firing at the cavalry, and the arrows of the stormy peninsula shot at the cavalry group, and the five thousand cavalry suffered extremely heavy casualties, and the Jurchen cavalry was frightened and scattered, and the cavalry behind turned around and fled to the north.

Wan Yanchang, who was standing in the distance watching the battle, was full of remorse, his heart seemed to be dripping blood, he couldn't hold back any longer, roared, and smashed his fist on the tree.

In just two short rounds, the Jurchen cavalry suffered more than 2,300 casualties, most of whom were hit by quenched iron pieces, and in the agony, these cavalry could not escape death.
