After receiving the news of the attack on Gaochengling, Yang Xin immediately shrank his troops and gathered all his strength to Xiangwu to make a key defense.

As an official who has been in Yongliang, even though Yang Xin has never dealt with the Shu army in person, she has a deep understanding of the tactics of defending the Shu army.

This tactic is almost the magic weapon for defeating the enemy from Sima Yi. Simply put, it is just a word of guarding. No matter how winds in the east, south, west and north, I will remain unmoved. If I master the essence of the word of guarding the word, I can be invincible on the battlefield in Longxi.

Of course, this kind of defense is not the kind of blind obedience and ignorance, but requires judging the situation and making flexibly adjustments according to the situation. The goals that should be protected must be protected, and the goals that should be abandoned can be optionally given up.

Sima Yi is the founder of Guanlong's defense tactics. When he was in charge of Yongliang, he used his turtle technique and tactics that kept firm and did not fight, so he killed the genius Zhuge Liang.

Zhuge Liang was a recognized military and political genius. Not only did he have a strategic height of three parts of the world, he also made many great achievements in the battles between the south and the north. It can be said without Zhuge Liang that Zhuge Liang supported most of the world of Shu Han. If it were not for Zhuge Liang, the Shu Han regime would probably not have been able to last for so many years. The Wei army's iron hooves might have already broken through the Bashan and Shu River.

As Sima Yi's capable confidant, Guo Huai became the core figure of Yongliang's defense system after Sima Yi left Yongliang. With more than 20 years of guarding experience, Guo Huai has always followed Sima Yi's defensive strategy, defended and fought back steadily, and did not give Shu people any chance.

Guo Huai has been doing his duties conscientiously and hardworking for the past twenty years. Especially after Sima Yi took office, Guo Huai naturally settled in Yongliang's position as the number one person, and did his best to build the Yongliang defense system.

This also has a lot to do with Jiang Wei's repeated offenses. After all, after Zhuge Liang's death, Shu Kingdom was silent for more than ten years and had no more weapons. The situation in Yongliang also became much more eased.

But since Jiang Wei took over the military power, Yongliang's situation has become tense again, with constant attacks and constant wars.

In order to consolidate the defense line of Guanlong, Guo Huai worked hard to build two fortress cities, Ji County and Chen Cang in Longxi, and used this center to focus on managing the county cities along the Wei River line and constructing a one-stop defense form of Longyou. Other cities, Wei Army may give up, but the cities on the Wei River line must be guaranteed and cannot be lost.

After all, the entire Longxi and even Guanzhong are maintained by a river. This river is the Wei River. The Wei River is called the largest tributary of the Yellow River. It has abundant water volume and developed river transportation. The Guanzhong area has become fertile and rich because of the nourishment of the Wei River.

Yang Xin has worked in Yongzhou for many years, so he is naturally well versed in Guo Huai's way of using troops. Longxi is vast and sparsely populated, and countless people are scattered. It is very unlikely to defend it. After all, Yang Xin has only 7,000 people, not 70,000 people, so he can only choose the risk and defend it. Except for Xiangwu, all other places were abandoned by Yang Xin. He concentrated his troops on Xiangwu, just to concentrate all his troops to defend Xiangwu to the death, and never let Xiangwu fall into the hands of the Shu people.

Before the Shu army invaded Xiangwu, Yang Xin was ready to defend Xiangwu. After all, the Shu army appeared in Gaochengling area in Longxi County. Obviously, the target of the Shu army's attack this time was Longxi County, and other places in Longxi County were not considered a key point. Only Xiangwu is the top priority of Longxi County's defense. Therefore, Yang Xin concluded that Jiang Wei would definitely come to attack Xiangwu and prepare in advance to be prepared for any trouble.

But Xiangcheng also has difficulty in defending, that is, the Weishui Ferry in Xiangwu. Xiangwu City is surrounded by mountains on three sides and faces water. It is almost natural to succeed. It is definitely not an easy task to break through the city wall of Xiangwu.

However, although the ferry of the Wei River is adjacent to Xiangwu City, it is outside Xiangwu City after all, and the defense power there is relatively weak, so how to defend it is indeed a difficult problem.

The first target of the Shu army was the Xiangwu Ferry. After Jiang Wei led his army to fight, he locked the first target of the attack as the Xiangwu Ferry.

Although Yang Xin had evacuated the relevant personnel from the Xiangwu Ferry in advance and transferred all the food and supplies stored at the ferry to the city of Xiangwu, at least the dozens of ships transporting food and supplies on the ferry had no way to evacuate into the city.

After unloading the cargo on the ship, Yang Xin ordered the ships to leave Xiangwu immediately and go downstream. As long as you flee along the Wei River to other county towns, you can ensure that there is no harm.

But the Wei army's actions were still a little slower, or the Shu army was coming too fast. The ship had just unloaded the cargo and had not yet left the Xiangwu Ferry, the Shu army's large group of troops rushed over and blocked the Wei River channel at once, intercepting all of these ships in the Xiangwu River section.

When the Wei River flowed through Xiangwu, the water surface was not too wide. If the Shu army really wanted to intercept it, it would be basically no difficulty. The Shu army only needed to throw a few thick trunks into the water to cut off the ships in the Wei River.

There was not much force on these ships, so the Shu army easily intercepted all of these ships without much effort. Even the only warship that escaped from the sky did not escape the interception of the Shu army.

The Shu army fought very resolutely in this battle. A thick tree trunk almost needed other people to cooperate. They shouted horns and threw the tree trunk into the Wei River. They hit a Wei army ship that was about to escape. The entire hull was penetrated by wood, and a large amount of river water rushed in. The ship immediately leaned towards the starboard side and crossed the water surface of the Wei River.

In this case, it was equivalent to the Wei army blocking its own way, and the remaining dozens of ships fell into the hands of the Shu army.

Jiang Wei took the lead in attacking the ferry this time, aiming at the dozens of ships on the ferry, not only the ships, but also the main targets were the supplies and food on the ship.

The Battle of Gaochengling seemed to have given Jiang Wei a little sweetness. After all, the Wei army's food and grass were to be supplied to Liangzhou. If the Shu army goes further, the grain channel may be completely cut off. At that time, the Wei army team entering Liangzhou will inevitably fall into a dilemma. Jiang Wei is full of expectations for this result.
