The Longxi problem was solved extremely smoothly. Of course, this was also a result of the Chencang Battle. In this Chencang Battle, the Wei army wiped out more than 70,000 Shu army and Sima army, almost half of which were destroyed. The Shu army and Sima army that were severely damaged were naturally full of loopholes in defense. Jieting's change of hands is the best proof that the Shu army's great defeat in Longxi is already irreversible.

Now Cao Liang's eyes have been aimed at Jiang Wei of Jiming Mountain. After losing Longxi, the Shu army of Jiming Mountain will inevitably fall into a state of being alone. In addition, Jiming Mountain is backed by Chen Cang Road, so Jiang Wei is likely to retreat to Hanzhong.

Since the Shu army currently controls the passage from Jiming Mountain to Sanguan, the Wei army basically cannot stop the Shu army from retreating to Hanzhong. They can only attack the Shu army from the direction of Jiming Mountain, and to the greatest extent, annihilate the Shu army's guards to the greatest extent, and count as much as they eliminate.

However, Yang Hu proposed a solution at this time, which was to take a detour to attack Sanguan and cut off the retreat of the Shu army.

Yang Hu's plan was very ruthless. If it could be realized, it would be equivalent to cutting off all retreats from the 70,000 Shu troops.

However, Cao Liang thought this was difficult to achieve. After all, Jiang Wei was not an ordinary person. He was well versed in strategy and was good at planning, especially when he retreated. He was the most experienced. How could he ignore the defense of Sanguan and give the Wei army an opportunity to take advantage of it? Jiang Wei would definitely send heavy troops to guard Sanguan. Therefore, Cao Liang believed that the opportunity to seize Sanguan was very slim. It would be better to concentrate troops to pursue the Shu army from Jiming Mountain, severely damage the Shu army's rear wing troops and eliminate the vitality of the Shu army.

But Huan Fan agreed with Yang Hu's plan. He believed that although Jiang Wei was prepared, Yang Hu's method was worth a try. Attack on Sanguan could also cause the Shu army to panic and unstable morale. This would be more conducive to the Wei army's attack on Jiming Mountain. It would be best if it could take Sanguan. Even if it didn't come down, the Wei army would not suffer much loss.

So Cao Liang ordered Yang Hu to lead his troops to the infantry battalion and Changshui battalion to attack Sanguan, and the remaining troops approached the line of Jiming Mountain. Cao Liang's order to Deng Ai was that the enemy would not move, and I would not move. If the enemy moved, I would move.

Before the Shu army retreated, the defense line of Jimingshan must be complete. If the Wei army launches an attack at this time, the losses will definitely be great. But if the Shu army starts to evacuate, it means that Jimingshan does not have enough troops to maintain the defense line. At this time, the Wei army's attack will definitely be twice the result with half the effort.

The main force of the Wei army was in Heisuyuan and temporarily remained unmoved. However, on the other hand, Yang Hu led the infantry battalion and Changshui battalion to stop and secretly launched an attack on Sanguan.

Although the straight line distance is not too far from Heishuiyuan to Sanguan, it has to cross a mountain range, with high mountains and dangerous roads and difficult roads. This march is indeed not easy.

Before departure, Yang Hu ordered the infantry battalion and Changshui battalion to keep all heavy equipment, vehicles and weapons in the camp. The two battalions were lightly launched. Each soldier only carried rations for seven days, and even took off his iron armor and put on extremely light leather armor. Only such outfits were conducive to light-fitting operations.

Climbing this mountain range is not easy. Although this is just a remnant of the Qinling Mountains, the mountains are steep and the difficulty of climbing is no less than that of the main mountain range. And like the main vein of Qin Xiao, this remnant also travels east-west. The only nearby valley is behind Jiming Mountain and is strictly controlled by the Shu army. If the Wei army wants to reach Sanguan, they must cross this mountain range.

The infantry battalion and Changshui battalion were the two earliest armies established by the Bingzhou Army. Their predecessors were both the Five Northern Army Clans. They followed Cao Liang to fight south and north and made great achievements. Therefore, even if there were thousands of difficulties and dangers in front of them, they could not help these two heroic troops.

Although Yang Hu is now promoted to the commander-in-chief of the Central Army, he has always served as an infantry general before. This infantry battalion is his direct unit. Yang Hu must know the infantry battalion better than anyone else.

With years of accumulation of combat experience, the infantry battalion has grown into a force that can conquer and fight tough battles. In the previous tough battles, there were almost no cities and fortresses that the infantry battalion could not capture. Other teams could not conquer the targets. As long as the infantry battalion took action, it would be easy to capture.

This sneak attack on Sanguan was not Yang Hu's sudden idea, but a bold plan made based on the conditions of the Wei army.

Now the road for the Shu army to retreat to Longxi was basically cut off as the Wei cavalry entered Longxi. Jiang Wei's plan to return to Shu from Qishan Road was basically ruined, so the only way to retreat for Jiang Wei was left was Chen Cang Road. There was no other way to retreat besides this.

Sanguan is the northern entrance to Chencang Road, and its geographical location is particularly important. If the Wei army can control Sanguan, it will be like successfully cutting off Jiang Wei's neck. The 70,000 troops have no way forward and no way to retreat, and they will inevitably fall into a desperate situation.

Since Jiang Wei advanced east from Longxi this time to rescue Chen Cang's Zhoutai, Yang Hu inferred that Jiang Wei could not carry too much food and grass. If the Wei army could cut off the retreat of the Shu army, then the Shu army in Jiming Mountain would definitely fall into the dilemma of no reinforcements and no food and grass, and would be defeated without attack.

It is precisely because of this huge profit that Yang Hu felt the need to take risks. Therefore, this time, Yang Hu changed his previous habit of being cautious in using troops and insisted on sending troops to attack Sanguan, giving Jiang Wei the heaviest blow.

Originally, Cao Liang was preparing to send other generals to lead the army, but Yang Hu believed that this plan was proposed by him, so he was responsible for the success or failure, so Yang Hu insisted on him leading his troops to attack, and Cao Liang had to agree in the end that when Yang Hu was preparing to only lead the infantry battalion to attack, Cao Liang transferred more Changshui battalion to him to ensure the Wei army's advantage in military strength.

Cao Liang didn't want Yang Hu to make any mistakes. Even if the attack was fruitless, at least he had to ensure that Yang Hu and his army could escape unscathed.

Yang Hu led his army to cross the mountains and ridges. Under the leadership of several guides, he finally reached Niujiao Mountain after a difficult journey.

The guides are local hunters. They often go to the deep mountains to hunt, so they are very familiar with the terrain of the Sanguan area. If these guides are really not guided, it would be almost impossible for the Wei army to get out of the mountains. This winding and winding bird path that is almost impossible to call the road is easily lost.

When the Wei army arrived at Niujiao Mountain, it was early in the morning. The mountains were filled with fog and there was no sight in front of them. However, the guide told Yang Hu with a confident look that the three miles south of Niujiao Mountain was Sanguan, which was not bad at all.
