Yang'an Pass is connected to Qinling in the north, Daba Mountain in the south, Yinping in the west, and Hanchu in the east, which is the only way for Xishu to enter Hanzhong, and it is no wonder that later generations often sigh that "the most dangerous is not as good as Yangping Pass" (Yang'an Pass was changed to Yangping Pass in the Song Dynasty).

Before sending troops, Zhong Hui repeatedly studied the geographical advantages of Hanzhong and the defense of the Shu army, and he believed that only by taking Yang'an Pass could he be regarded as taking the key to open the gate of Bashu, and if he couldn't take Yang'an Pass, the entire plan to cut down Shu might be aborted, and there would even be the danger of annihilation. Therefore, after Zhong Hui entered Hanzhong, he only surrounded the two key passes of Lecheng in Seoul, and all the main forces rushed to Yang'an Pass at all costs, and they wanted to capture this dangerous pass at all costs.

Zhong Hui knew very well that the 7,000 defenders of Yang'an Pass alone were not enough to pose a threat to the 100,000 Wei army, and the only thing that made him jealous was Jiang Wei's 50,000 horses in the city. It is almost impossible to expect Deng Ai's 30,000 troops to eat Jiang Wei, and Zhong Hui does not have this luxury, as long as Deng Ai can successfully stumble over Jiang Wei, it is enough.

In order to have an extra layer of insurance, at the same time that Deng Ai sent troops, Zhong Hui ordered Yongzhou Assassin Shi Zhuge Xu to lead 30,000 troops to seize the Yinping bridgehead and cut off Jiang Weidong's path to Yang'anguan, which was a foolproof plan.

However, Yang'an Pass is connected to Hanshou in the south, although Zhong Hui's grasp of intercepting Jiang Wei's main force to return eastward, but he can't stop the reinforcements from Chengdu, once Chengdu knows that Yang'an Pass is in danger, it will definitely increase Yang'an Pass in a big way, and at that time, Yang'an Pass will be difficult to overcome.

However, it is more beneficial to Zhonghui that Chengdu to Yang'an Pass is separated by thousands of miles, and Shu Road has been difficult to go to the blue sky since ancient times.

Xu Yi was in a hurry, led the troops to rush to the city of Yang'an Pass, neither camped in the village, nor observed the enemy's situation, and directly waved the army to attack Yang'an Pass, in Xu Yi's words, he camped in the city of Yang'an Pass tonight, why bother to camp outside the city in one fell swoop. Xu Yi ordered all the armies to attack the city together, and after breaking the city, they buried the pot to make rice, killed pigs and sheep, and rewarded the three armies.

The Wei army set out from Guanzhong and marched long, and did not encounter any threatening resistance from the Shu army along the way, which undoubtedly fueled the arrogance of the Wei soldiers.

There were no large-scale siege equipment, so the Wei soldiers carried simple ladders and relied on crowd tactics to rush towards Yang'an Pass frantically.

They were greeted by a dense rain of arrows in the city, and the sharp arrows shot through the bodies of the Wei soldiers without hesitation, and in the rush forward, the Wei soldiers continued to fall, but this casualty did not seem to hinder the high morale of the Wei army, and the Wei soldiers attacked the trench under the Yang'an Pass in front of the rain of arrows.

This is a deep trench, in front of the trench, densely covered with horses and antlers to defend against the enemy's cavalry, if you want to rush to the city, the Wei army must destroy the antlers and fill the trench. For the warlike Wei army, this did not seem to be a problem, and the sappers with large axes and saws in their hands had already begun to work, clearing the horses and antlers in front of the trenches, and more Wei soldiers shouldered sandbags and threw themselves into the deep trenches.

But the location of the trench is the best range of bows and arrows, at this time the rain of arrows on the city is more dense, pouring down like a shower, in front of the trench, lying all over the Wei soldiers' corpses, blood flowing, corpses pillows.

Not to be outdone, the Wei army immediately called a large number of bed crossbows and archers, suppressed the head of Yang'an Pass, and the two sides launched a bow and arrow attack battle at a long distance, the arrows in the sky were like flying locusts, covering the sky and the sun, and the city was under the city, constantly sending out a dying scream of death, but the density of the arrows never decreased, and both sides spared no effort to fight for the suppression of the bow and arrow.

In the offensive and defensive battles of the city, the attacking side will definitely pay a greater price than the defending side, especially when there is a lack of large-scale siege equipment, this gap is even more obvious. After paying a heavy price in casualties and filling the trench with sandbags, stones and soldiers' bodies, the Wei army finally attacked the city of Yang'an Pass.

But the real bloody battle has just begun.

Countless ladders were erected, and the Wei soldiers began to step on the ladders, struggling to climb towards the top of the city. In addition to bows and arrows, the rolling logs and stones also began to exert power, those thick rolling logs almost had to be lifted by the combined efforts of several soldiers, and they were lifted high above their heads, whistling and rolling down, and a rolling log could almost sweep the Wei soldiers on several cloud ladders, and everywhere they passed, they were unstoppable. The heavy stone is even more domineering, smashed on the top of the head of the Wei soldiers, immediately the brain bursts, the flesh and blood are blurred, the bamboo wooden ladder can not bear the weight of the stone, once it is hit, it immediately breaks from the middle, and the strings of Wei soldiers on the ladder are immediately thrown down.

There is also boiling water and boiling oil, and if you pour it down, there will be a terrible scream underneath.

Fu Yan's expression was solemn, calmly commanding the battle, although the arrows shot by the Wei soldiers flew by his ears whistling, Fu Yan still sternly rejected the Chinese officer's suggestion to let him retreat, Yang'an Pass has reached a critical moment of life and death, he is the main general, there is absolutely no possibility of taking half a step back, he is in, the morale is there, the brave wins when they meet on the narrow road, as long as the morale of the defenders of Yang'an Pass is condensed, even if the Wei army is huge, it will not want to cross half a step.

Under the supervision of Fu Yan, the Shu army was united, the soldiers at the forefront fell, and the reserve soldiers immediately went up, looking up from the city, the head of Yang'an Pass seemed to have never been less than one person, and each soldier stuck to his post and never flinched.

The corpses are piled higher and higher, but this cannot stop the strength of the Wei army's attack, under Xu Yi's supervision, the Wei army's offensive is like a tide, wave after wave, in this blood-soaked land, death has made people numb, no one is afraid, and no one retreats, stepping on the corpse, except for attacking or attacking.

But the defense of Yang'an Pass is as stable as a rock, no matter how crazy the Wei army is, this city wall is their insurmountable hurdle, in the remnant sun, countless cloud ladders were burned by fire, blood, firelight, sunset, eyes full of red can no longer see other colors.
