Yang Hu completed the occupation of Jiaozhou, which means that Cao Liang could start the battle to attack Shu at any time. Not only did the two legions of Deng Ai and Du Yu participate in the battle, but Yang Hu's side also launched an attack at any time.

In Cao Liang's plan, the ultimate version of the three armies attacking Shu is the one.

In history, there were basically two routes: Hanzhong Jiange to the north and Yong'an Jiangzhou to the east. In history, Qin destroyed Shu and Wei destroyed Shu. He walked the north road, first took Hanzhong, then Jiange to attack Chengdu.

When Liu Bei entered Sichuan and took Yizhou, he took the East Road, first to take Yong'an, then Jiangzhou, and finally captured Chengdu.

These two routes are the most classic routes to Sichuan. Of course, there are other routes, such as taking Brazil directly from Shangyong and the Qiang Road west of Chengdu. However, these routes are undoubtedly more difficult and narrow, and are not conducive to the large army's operations. Therefore, for thousands of years, the battles into Sichuan have basically been locked on these two routes.

The road to Shu is difficult, and it is harder than to reach the sky. Shu is the weakest among the Three Kingdoms, and its strength is incomparable to Wei and Wu. However, since Liu Bei obtained Yizhou, the Shu Han regime has been maintained for half a century. It can stand firm for such a long time, which shows that it has a strong side. Otherwise, how could this world where the strong prey on the weak have a place?

The biggest advantage of Shu Kingdom is its geographical advantage. There are two natural dangers of Qinling Mountains in the north and the Three Gorges in Wushan in the east, just like two gateways, firmly guarding the fertile land of the Tianfu Kingdom.

Of course, such geographical conditions are also a double-edged sword. When Zhuge Liang was persistent in the Northern Expedition, it was because of the high mountains and dangerous roads and the difficulty of transferring food and grass, which made Zhuge Liang very difficult when planning the attack. Even a genius, facing such complex and dangerous geographical conditions, he could only sigh at the mountains.

Although it was difficult for Shu Kingdom to attack, they were very relaxed to defend. Wei Kingdom had used troops to Shu Kingdom twice. The first time was Cao Zhen and Sima Yi attacking Shu Kingdom, and encountered a month of rain. Originally, Shu was high in mountains and roads, and the weather was a monster. In this attack, even the Shu army was not seen, so they stopped their troops early.

The second attack was Cao Shuang's attack on Shu. After Cao Shuang took office, he was eager to change his embarrassing situation of not having military achievements. When the conditions for attacking Shu were not mature, he rashly mobilized a large army to attack Shu.

At that time, Cao Liang also participated in this battle as a Yueqi captain. Although the Wei army successfully invaded Hanzhong, it was strongly blocked by Wang Ping, Jiang Wei and others. After being defeated in Xingshi, Cao Shuang almost became a prisoner at the bottom.

These two few experiences of attacking Shu undoubtedly laid a lot of haze in the hearts of the Wei people. In the nearly twenty years after Cao Shuang attacked Shu, the Wei Kingdom had never used troops to Shu. In the battles on the Guanlong line, they were basically defending themselves. Jiang Wei kept sending troops to the northern expedition and constantly disturbing Guanlong. Although he had not obtained any inch of land, he kept disturbing the Yongliang land and uneasy.

The Wei army in Yongliang was holding his breath. Jiang Wei sent troops to disturb Guanlong so many times, which made the Longxi area uneasy. The Wei army in Yongliang wanted to send troops to fight back and taught Jiang Wei a lesson, so that he would stop acting so arrogantly and be arrogant.

However, attacking Shu is a strategic point. Not only is the ordinary soldiers of Yongliang powerless, but even the successive governors of Yongliang have no right to decide. If you want to attack Shu, you must be determined at the court level.

Of course, over the years, the power struggle between Cao Liang and Sima has also made the Wei State look unscrupulous. Being able to take a defensive position in the Yongliang area would not make the Shu fisherman profitable. This is actually a very good record.

The previous governor of Yongliang, Guo Huai, performed very well during his tenure. Although Cao Liang and Sima were fighting fiercely in Guandong, Guanzhong and Longxi have always been as solid as rocks. Although Jiang Wei repeatedly attacked and tried to fish in troubled waters, he could not get any benefits and could only return in disappointment.

Cao Liang destroyed the Sima family and gained control of Yongliang, and Deng Ai also became the new governor of Yongliang. Compared with the Guo Huai era, the Yongliang army in the Deng Ai era was stronger. In the two battles in Longxi, the Wei army severely damaged the coalition forces of Jiang Wei and Sima Lun, recaptured the five counties of Longxi controlled by the Shu army, and drove Jiang Wei back to Hanzhong again.

And after the failure of the second Battle of Longxi, Jiang Wei also left Hanzhong and moved to Yong'an. Obviously, Jiang Wei himself also thought that the road from Guanlong to the northern expedition was not accessible, so he finally chose to give up.

The Yongliang Land finally ushered in peace. Without Jiang Wei's disturbance, even the soldiers guarding the border could sleep peacefully.

But for the Wei army in Yongliang, they were holding their breath secretly. In the past, they were always beaten and beaten, and they could only passively respond, but they could not fight back. Such a battle made them extremely frustrated. As long as they were Yongliang's soldiers, whether they were from the old or the new generation, the thing they thought about most was to beat the Shu army quickly and express the resentment they had been holding in their hearts for many years.

It is impolite to come but not go. How could the Wei army be beaten by the Shu army for so many years? Even if it is a fight on the street and beaten by others, it always has to find a way to return it.

But over the years, the Shu army has always taken action, and the Wei army has always been beaten. Even if the Shu army did not get any advantage in the end, the obstacles in the minds of the Wei army soldiers may not be able to overcome.

Therefore, since Jiang Wei was transferred from Hanzhong and there was no war on the border between Wei and Shu, the soldiers of the Wei army asked Deng Ai to send troops to attack Shu, hoping to avenge a single arrow.

However, even Deng Ai, as the governor of Yongliang, had no right to make decisions at this strategic level. Deng Ai also tried to write a letter to Cao Liang to ask for battle, but Cao Liang gave him a word to keep him calm, so Deng Ai dared not do anything more.

Deng Ai knew that attacking Shu was a strategic matter. As the emperor, Cao Liang had to consider more things than ordinary people. As the governor of the Left Army and the governor of Yongliang, Deng Ai only needed to consider the affairs of the Left Army and the affairs of the two states of Yongliang, and Cao Liang had the world in mind.

So the standing height is not high, and the perspective of the problem is different. Deng Ai knows that there will definitely be a battle to attack Shu in the future. However, the time is not right now, and Cao Liang asked him to be calm, so Deng Ai can only wait patiently.

All he has to do now is to prepare for war and actively prepare for war. When Cao Liang's order is given, Deng Ai will come when he summons him and can fight when he comes.
