Before the New Year holiday, at the end of November and the beginning of December, the Wei army completed the assembly in Hanzhong and Nanjun.

Before the New Year holiday, a large amount of beef, mutton, fish, chicken, and duck meat that Guo Peng gave to the frontline soldiers arrived at the frontline.

A large number of excellent military cooks tried their best to cook meat for the soldiers during the New Year's holiday.

Guo Peng also sent someone to announce the holy decree, saying that he would give the soldiers a good sticker during the New Year's holiday, which would help them better exert their physical advantages in the war and earn a wave of military morale.

Compared with the Shu army, which was assembled from all over Shuzhong and was assembled nearly a month later than the Wei army, the Wei army was simply waiting for work.

The soldiers were full of energy, and the soldiers from other places adapted to the local climate in advance and adjusted their spirits to the best state.

By the end of the first year of Yande, the overall strategy and tactics of the Wei army had been fully formed, and it was reported to Luoyang to the emperor Guo Peng, who sent it to the staff station for verification, and then sent it to the front-line troops to confirm the implementation.

The staff officer Zuo Servant shot Guo Jia and rushed to Nanjun again to supervise the battles of the armies on the Nanjun side.

Xun You, who was transferred from Henan Yin to serve as a staff officer, was also appointed to rush to Hanzhong to participate in war guidance and supervise the participation of Hanzhong armies in battles.

The position of Henan Yin was taken over by Zhang Zhao, an official of Shangshutai.

At the same time, Pang Xi, who dedicated Hanzhong to Guo Peng, was transferred from the Taishou of Hanoi County to the staff station, and also went to Hanzhong with Xun Yu as a staff officer.

The position of the Taishou of Hanoi was taken over by Zhang Hong, an official of Shangshutai.

Not only that, Guo Peng also ordered that Fa Zheng and Deng Zhi, who had surrendered with Pang Xi, be transferred from the county order positions in Hanzhong to the staff officers of the staff station, under the leadership of Xun You, and participate in the battle of Shu of the Hanzhong Front Army.

Guo Peng mobilized Liu Zhang's subordinates to participate in this war together, raising the familiarity of the Hanzhong Front to the top, and allowing a large group of people who were familiar with the road to serve in staff positions to avoid mistakes due to road problems.

As for Nanjun, there are more people who are familiar with the road, Guo Peng is not worried, Guo Jia is also an old acquaintance of Lejin, and the two have a tacit understanding, and there is no problem.

As for Guan Yu and Xun You......

Guo Peng was very worried that Guan Yu's arrogant character would make a mistake again, and he would be dissatisfied with Xun Yu, who was tainted in his temperament, and he would cause some problems.

So after thinking about it, out of trust in Xun You's desire to survive, Guo Peng chose to grant Xun You Jieyue, so that Xun You could forcibly control Guan Yu at a critical moment, so that Guan Yu had to obey orders.

And if this kind of thing really happens, Guo Peng will definitely settle accounts with Guan Yu after the war, and he can't let Guan Yu feel that he is a veteran and can do whatever he wants.

By the middle of the first month of the first year of Yande, the preparations for both Hanzhong and Nanjun had been completely ready, the logistical mobilization of the Minfu and auxiliary troops had also been completed, and the Minfu and auxiliary troops from all parts of Hanzhong and Nanjun had also been assembled, and the official battle could begin.

So, on the twenty-first day of the first month of the second year of Yande, Guo Peng issued an order to march and sent the marching tiger talisman to Hanzhong and Nanjun.

On the twenty-sixth day of the first month of the second year of Yande, the tiger talisman was delivered to Hanzhong and Nanjun respectively, and the tiger in the hands of Guan Yu and Le Jin was close together, and the battle officially began.

According to the previous plan, Guan Yu would abandon the road of Micang Mountain, and only place a partial division in Micang Mountain to play a feint, and he directly led the main force to take the Shiniu Road and directly attack Chengdu.

Through the introduction of Pang Xi and others, Guan Yu learned that the most important pass on the Shiniu Road was the Sword Pavilion, and if the Sword Pavilion could be breached, there would be no more obstacles to the road to Chengdu.

If you can't break through the Sword Pavilion, then the road to Chengdu will be blocked, and there will be no other more suitable path to take.

The Shu Road is so difficult, and the road to the Chengdu Plain is so difficult, which not only protects the Chengdu Plain, but also greatly limits the possibility of the Shu people winning the country.

Having said that, it was not easy for Guan Yu to move forward.

Before the army started, Guan Yu had already ordered the scouts to explore forward in accordance with the usual practice, and ordered the logistics troops transporting grain to advance first to create a garrison rest point for the army.

The so-called three armies did not move the grain and grass first, and marched in a place like Yizhou, where the road conditions were very bad, then the importance of grain became even more prominent, and it can be said that whether the war can be won or not depends entirely on the grain route.

Before the army attacked, the scouts had explored the road ahead, and the Shu army seemed to have given up on useless resistance north of the Sword Pavilion and concentrated its main forces on the Sword Pavilion.

This is actually a good thing for Guan Yu, because it means that Guan Yu can not worry about the problem of the grain road, and he can go deeper into the grain road in one breath without wasting more time.

Regarding the threat of the Guanghan vassal state, Gao Lan, the commander of the garrison of Wudu County, had already received a direct order from the staff station.

In order to respond to the advance of Guan Yu's army and protect Guan Yu's grain route, Gao Ran wanted to lead the army into the Guanghan subject country to suppress many foreign tribes in the Guanghan country.

Ensure that they will not attack Guan Yu's grain route because of Liu Zhang's bribery, and create conditions for Guan Yu's smooth march.

So Guan Yu marched all the way, and sure enough, he did not encounter resistance from the Shu army, and the grain route was also very safe.

Guan Yu's vanguard Cao Xiu only encountered a few Shu troops in Baishui, and it seemed that it was not for defense, but to confirm whether the Wei army had begun to attack, and then quickly went back to report without much entanglement.

Finding that the Wei army was coming towards the Sword Pavilion, the Shu army immediately began a full mobilization, and Wu Yi immediately put on the battlefield and went to the front line to conduct a comprehensive inspection of the defense of the Shu army near the Sword Pavilion to ensure that the defense of the Shu army was real and effective, and would not be easily broken by the Wei army.

After marching for more than ten days, by the ninth day of the second month of the second year of Yande, Guan Yu had already led the army deep into the vicinity of the Sword Pavilion.

By observing the nearby terrain, combined with the explanations of Pang Xi and others, Guan Yu and other Wei generals found that this was indeed a dangerous place where a husband and a wife could not be opened.

Ascending the steep mountain, you can see the Sword Pavilion Pass in the distance, Guan Yu found that the road in front of the Sword Pavilion Pass City is very narrow, not enough for the army to deploy, and it is very convenient for the army on the Pass City to defend.

The city is very high, and it is impossible to enter the city without a cloud ladder, and the Shu army is condescending, using bows and crossbows, boiling oil, rolling wood and stones, and even gold juice, which can cause great damage to the Wei army.

The Wei army was limited by the width and length of the offensive road, and it was difficult to give full play to the advantages of troops and combat power, and the offensive road was locked, almost a live target for the defenders in the city, and it was impossible to launch an attack at all, and its own casualty rate was bound to be very high.

After realizing this, Guan Yu ordered the army to slowly retreat, looking for a slightly open place to camp along the river to ensure the stability of the grain route, and prepare for a protracted war.
