The summit of Jigong Mountain is about fifty or sixty zhang high from Yang'an Pass, and from here you can have a bird's-eye view of Yang'an Pass, almost unobstructed. The horizontal distance from Jigong Mountain to Yang'an Pass is only about forty or fifty steps, Ah Jian tried to throw a grenade, and sure enough, it can be easily thrown onto the city wall, but the time to fall is relatively long, and this grenade has exploded before it lands.

Ah Jian ordered his subordinates to adjust the length of the fuse and bombard this section of the city wall near Jigong Mountain in Yang'an Pass. Ah Jian prepared more than 200 bamboo grenades and thousands of gunpowder arrows, and the section of the city wall south of the target was only about 100 steps. Although the stone walls of Yang'an Pass were quite strong, and these grenades could only hurt some fur, the damage to the flesh and blood of the Wei soldiers was fatal.

The dense formation used by the Wei army in the defense of the city wall is basically people by people, and people rely on people, such a defensive formation is very effective for resisting the Shu army's ant-attached siege method, even if a part of the Shu army breaks through the city wall and attacks the city, it can also be pressed down by the Wei army's dense defensive formation.

But such a formation undoubtedly provides a place for grenades, after a grenade explodes in the crowd, the huge shock wave is almost devastating within a radius of one zhang, Wei Bing has zero experience in guarding against gunpowder weapons, and does not know how to lie down and other protective measures, one by one they are first stunned, standing there stupidly waiting to be bombed, and then they are rushing like headless flies, and the whole city is in chaos.

Ah Jian coldly ordered his soldiers to keep throwing bamboo grenades and gunpowder arrows at the city, and soon the entire city was plunged into a sea of fire. The violent explosion blasted the stone chips all over the air. At the head of the city within a hundred paces. There was almost no place for the Wei soldiers.

Seeing that this round of bombardment had achieved the expected effect, Ah Jian suspended the attack and raised the flag to signal the Shu army under the city to launch a siege operation.

The Hancheng camp of the Shu army, which was already ready to go under the city, was like a tiger out of the forest at this moment, taking vigorous steps, carrying a cloud ladder, and rushing towards the city wall of Yang'an Pass, and the shouts of killing resounded.

At this time, the head of Yang'an Pass has been baptized by artillery fire. Except for a piece of stumps and broken arms, there was not a single living person in this area, and the siege of the Shu army was not hindered in the slightest, and the soldiers stepped on the ladder and climbed towards the city.

Li Fu, who had already retreated, was worried this time, and when he saw that the bombardment of the Shu army had stopped, he immediately ordered the Wei soldiers to counterattack, preparing to plug this gap.

But it was easy to retreat, and it was too late to make up for it, and the Shu army's movements were quite fast. Before the Wei soldiers rushed up, the first wave of Shu soldiers had already jumped onto the city.

This time, Ah Jian was not idle on Jigong Mountain. Although grenades could no longer be thrown in the area where the Shu army landed in the city, the two sides of this area and the deep area within the city walls could still be thrown, and the artillery fire continued all the way to continue to strike at the Wei army's ranks.

After the first wave of Shu troops attacked the city, the whole situation was like a flood that broke the embankment, and it could no longer be suppressed, and more Shu troops poured towards the city, and the Wei army launched a fierce hand-to-hand battle on the city wall.

Once the advantage of the city wall was lost, the numerical disadvantage of the Wei army was clearly revealed, and in hand-to-hand combat, more and more Shu troops joined the battle group, constantly attacking the Wei army's position, and gradually expanding the occupied area.

The Wei soldiers, who had already been blown up by bombs, were defeated and retreated under the repeated impact of the Shu army's foot soldiers.

In the fierce battle, the city gate was also lost, and the Shu army attacked the city from the city gate, and the advantage occupied by the Shu army was further expanded, and the defeat of the Wei army was irreversible.

Fang Hong's face was anxious, and he said to Li Fu: "General Li, the general trend is over, hurry up and break through!" ”

Li Fu is face was disgraced, his eyes were gloomy, he never expected that the solid and rock-solid Yang'an Pass would lose to Liu Yin's new weapon, a deafening explosion completely destroyed Li Fu's confidence in sticking to Yang'an Pass, and he still couldn't hold out until Zhonghui's reinforcements arrived.

Now the Shu army has entered the city in a big way, embattled, even if it is not easy to break through, not to mention that Li Fu is deeply entrusted by Zhonghui and sits in Hanzhong, but the final result turned out to be a complete defeat, and Li Fu felt that he did not have the face to see Zhonghui.

"It's better to be broken than to be complete!" Li Fu said in a deep voice slowly, two cold rays shot out of his eyes, he pulled his sword in his hand, looked around at the soldiers around him, and shouted: "There is no enemy and no me, there is no enemy and I am invincible!" Kill! ”

Li Fu rushed into the Shu army formation with his sword first, and those Wei soldiers, under the inspiration of Li Fu, also raised their weapons one after another, and launched a desperate fight with the surging Shu army.

But the enemy was outnumbered, and Li Fu was finally hit by several arrows and died at the crossroads of Yang'an Pass. Fang Hong risked his life to break through the siege, but more and more Shu troops blocked his way out of the city, Fang Hong rushed left and right, but failed to break out of the siege, and finally died under the chaotic knife of the Shu army.

The battle of Yang'an Pass finally came to an end, the Wei army of more than 10,000 people, nearly half of the war dead, the other half of the Wei soldiers in the main general died, the general situation has gone, disarmed and surrendered, Yang'an Pass in the fall of one year and seven months, finally returned to the hands of Shu Han.

Liu Yin knew that the loss of Yang'an Pass had become a lingering pain in Fu Yan's heart, although the Shu army had made a series of great victories in the land of Guanlong, but between Fu Yan's eyebrows, there was always a faint sadness, it was obvious that Yang'an Pass had become an eternal pain in Fu Yan's heart, and if he didn't get Yang'an Pass back for a day, Fu Yan's heart knot would not be untied.

It is a pity that Fu Tong did not have the opportunity to experience the recovery of Yang'an Pass this time, but Liu Yin believes that after Fu Tong got the information of the recovery of Yang'an Pass, a big stone in his heart can finally land.

Taking Yang'an Pass is equivalent to taking the entire territory of Hanzhong in the palm of your hand, and it can be regarded as completely sealing Zhonghui's way back. After Liu Yin entered Yang'an Pass, he immediately ordered the city defense of Yang'an Pass to be repaired, and the damaged city wall was repaired overnight, and the defense in the city was actively deployed.

With the fall of Yang'an Pass, Zhong Hui's army has really become a lone army, with no logistics supplies, no food and grass, and it is completely in a desperate situation, Liu Yin can imagine seeing Zhong Hui's face after knowing it, where will the 100,000 Wei army go, this will be the time to test Zhong Hui's wisdom.
