Since the Wei army had occupied most of Hanzhong, it became much easier to send messages to Xiling. There was no need to send them to Guanzhong and then head south from Wuguan. Instead, they directly lead from Hanzhong to Shangyong, and directly from Shangyong to Xiling.

If you pass the fastest Yima, it will only take about seven days at most to deliver the memorial to Xiling.

At this time, Cao Liang had arrived in Xiling and participated in the command of the battle to attack Yong'an. The five battalions of the Right Legion and some of the naval fleets had all arrived at the Yong'an front line and launched an attack on the Yong'an defense line of Shu Kingdom.

Compared with the invincible progress of the left legion on the northern line, the attack of the right legion on the central line was not very smooth. The main reason was that the Shu army assembled 100,000 troops in the Yong'an area and relied on Yong'an's solid defense line to carry out tenacious resistance, which led to the hindering of the right legion's advance. After more than a month of fierce fighting, the Wei army failed to break through Yong'an's peripheral defense line.

This made the soldiers of the Right Army who participated in the war worried. The three armies of the Wei army besieged Shu Kingdom, and everyone wanted to compete for the first achievement of destroying Shu. Although the Central Army has not moved and there is no sign of sending troops, the Left Army is extremely powerful. In less than a month, even the three counties of Hanzhong, Yinping and Wudu have made great progress.

At this speed, the left legion was just around the corner to fight to Chengdu, but the right legion was blocked outside Yong'an City and had no time to make progress. If it really developed at this pace, the right legion would not be able to make any contribution this time.

So the generals of the Right Army all asked Du Yu to fight, asking Du Yu to send his army to the attack, striving to seize Yong'an as soon as possible and open the eastern gateway to Sichuan.

But Du Yu was in a dilemma. To be honest, Du Yu himself was also dissatisfied with the current situation, but the plan to launch an attack on Yong'an was not something Du Yu could decide alone. After all, the Central Army had His Majesty Cao Liang's commander in person, and he, the governor of the Right Army, did not have greater autonomy like Deng Ai and Yang Hu.

Although Cao Liang did not interfere too much in the tactical arrangement, Du Yu may not be able to make any decision at the strategic level.

The offensive plan this time was basically formulated by Cao Liang. Although Du Yu, Deputy Governor Shi Bao, Liu Jing and Navy Governor Wang Jun also participated, Cao Liang's opinions occupied the majority, and the others only played an auxiliary role.

In Cao Liang's plan, although the Right Legion was strong, it did not really invest too many troops in the attack, and even the naval fleet had more troops than the Right Legion.

Cao Liang's arrangement made the generals of the Wei army very confused. Since the Wei army had started the battle to destroy Shu, we should not be afraid and launch an attack with all our strength. Even if the Shu army's defense in Yong'an is strong, for the Wei army, which is invincible in the case of attacking, this small difficulty can be overcome. As long as they give their all their strength to launch an attack, many people do not believe that they cannot defeat Yong'an.

As for the cost of casualties, there must be one. If there are immortals in the war, it will be worth it if they can successfully win Yong'an, even if they pay some price.

However, Cao Liang seemed calm and composed. The Wei army failed to defeat him repeatedly, and Cao Liang seemed calm and unhurried.

After all, Cao Liang's level of consideration must be more profound than the generals of the Right Legion. The battle against Shu is a big game of chess, and each legion is like chess pieces on a chess board. How to use these pieces more efficiently to achieve the goal of effectively attacking the enemy's chess pieces is what Cao Liang needs to consider.

Yong'an has a dangerous terrain, which is the gateway to the east of Shu Kingdom. It gathers more than 100,000 troops from the Shu army, accounting for more than half of the Shu army's strength. If the Wei army launches a strong attack here, it will not be easy for the Wei army to capture Yong'an with the defense capabilities of the Shu army.

In order to avoid major casualties, when launching an attack in the middle, Cao Liang did not let the Right Army do his best, but instead adopted a restraining style of play.

In fact, Cao Liang's purpose was also very simple, which was to drag the Shu army's troops to Yong'an and not give them the opportunity to reinforce elsewhere. In this way, the Wei army's attack would become simpler and easier in other directions.

Cao Liang actually had high hopes for Deng Ai on the Northern Line. In real history, Deng Ai was a hero in destroying Shu. His magical stroke of smuggling through Yinping Path was called the most famous surprise attack in history.

Now Deng Ai has successfully captured the three counties of Hanzhong, Yinping and Wudu on the northern line. The troops are approaching Jiange, attracting the attention of the main force of the Shu army. If Deng Ai uses his magical hand at this time, raids Jiangyou from the Yinping path and enters the Shuzhong Plain in one fell swoop, then the situation of Shu Kingdom will collapse like a collapse, and the destruction of Shu is just around the corner.

In the prior communication, Cao Liang and Deng Ai did not mention the attack from Yinping Path. For Deng Ai, the preferred attack direction is Jiange. I am afraid that he would consider marching from Yinping Path when the attack from Jiange was blocked.

Since sneak attack on Yinping Road was an alternative plan and it also needed to be kept strictly confidential, Deng Ai did not negotiate with Cao Liang on this matter in advance.

However, even if Deng Ai did not report Cao Liang in advance, Cao Liang knew this very well, because he knew that with the defense of Jiange, no army could break it from the front for thousands of years. It was difficult for Deng Ai to open Jianmen Pass from the front.

If Deng Ai had no success in attacking Jiange, he would have a high probability of going back to Yinping Path and attacking Chengdu from that remote route.

This is of course related to Deng Ai's personality. Deng Ai's military use has always been known for being a strange and dangerous person. He often takes a wrong approach and often has unexpected things.

Cao Liang had never communicated with Deng Ai about the raid on Yinping Xiaodao, and he would not accept the orders of the outside king. Due to the unmatched relationship, Cao Liang was relatively relaxed in the military operations of Deng Ai. He believed that with Deng Ai's ability, he could handle all matters on the front line well. He was on the middle side, so he just needed to wait for good news.

After the Wei army captured Hanzhong, the post station passage between Hanzhong - Shangyong and Xiling was quickly established, which was of great benefit to Cao Liang's timely grasping the battle situation on the Northern Line. In the past, it often took ten days and half a month to pass the Guanzhong memorial. Now it has almost reduced the time to half, which is much more convenient and quick.
