Yan Yu was a monster in Hanzhong, and it was not afraid of Jiang Wei's hind legs invisibly. Only Zhong Hui in Dazhong still made Deng Ai a little afraid.

Zhong Hui's troops had about 30,000 people, almost all of them were Sima Lun's subordinates. They were brought from Guanlong when Sima Lun surrendered to Shu.

During the Battle of Longxi, Sima Lun suffered heavy losses. Originally, more than half of the 100,000 troops were lost, and in the end only 50,000 were left. This was also the only remaining troops of the Sima family. They followed Sima Lun to surrender to Shu and stationed in the Yinping Wudu area centered on Dazhong, and were fully responsible for the defense of the West Road of the North Line.

Later, the later ruler Liu Chanxuan summoned Jiang Wei Simalun and others to meet him, and Simalun left Zhong Hui to stay here and temporarily took over his post.

According to Sima Lun's plan, he would still return to Dazhong after meeting the saint this time, but unexpectedly, after arriving in Chengdu, Liu Chan saw that Sima Lun was so capable and admired him very much, so he hired him as his son-in-law and stayed in the capital.

Later, the war in Xiling was in a tight position, and Sima Lun volunteered to help the battle. He drew 20,000 troops from Dazhong to reinforce Jiang Wei, so Dazhong's defense was handed over to Zhong Hui, and the court officially promoted Zhong Hui to General Zhenxi and Governor Yinping, so he was responsible for Dazhong's defense in full.

The position of Dazhong is no less than that of Hanzhong. The border between Wei and Shu is relatively long. Hanzhong only occupies the eastern section, while the Yinping and Wudu defense lines in the western section are also extremely important. If the Wei army seized the two counties of Yinping and Wudu, then not only the Shu army in Hanzhong is facing the danger of being attacked from both sides, but the Wei army can also go south from Guancheng Baishui, directly threatening the safety of Jiange.

Jiange is the gateway to Shu. After passing Jiange, it will be a vast plain in Shu, with almost no danger to defend. Therefore, once Jiange is lost, Shu will directly surrender with the white flag.

In order to protect the safety of Jiang Ge, Jiang Wei specially established two major defense lines in Hanzhong and Dazhong, blocking the Wei army north of Bashan and preventing them from getting close to Jiang Ge. This is the safest defense. After all, although Jiang Ge is dangerous, it is also very dangerous if the Wei army is really put under the pass. Of course, Jiang Wei does not want such a situation to occur.

Therefore, the defenses of Hanzhong and Dazhong are extremely important. No matter which one of these two important places is lost, they will be an immeasurable loss for Shu Kingdom.

The defense system in Hanzhong was established by Jiang Wei. Although Dazhong's defense was handed over to Sima Lun, Jiang Wei also seriously participated in the planning of Dazhong's defense system. At present, Zhong Hui is also implementing Jiang Wei's defense plan in Dazhong, sticking to various strategic points in Dazhong.

Zhong Hui was also a very strategic general and was Simalun's most trusted confidant. Therefore, after Simalun left Dazhong, he dared to hand over the full authority of Dazhong's defense to Zhong Hui for handling.

After receiving the order, Zhong Hui was also very diligent. He had to inspect and deploy all the fortresses in person. He had thought about how to arrange troops and arrange them carefully. Zhong Hui never let go of any details.

After all, Zhong Hui also knew the importance of Dazhong's defense, so he did not dare to slack off since he was ordered, and many things were done by himself.

The only thing that is lacking is the problem of the troops in Dazhong. According to Jiang Wei's original plan, Sima Lun's 50,000 troops stationed in Dazhong, so that each key pass has corresponding troops to garrison.

But after Sima Lun drew 20,000 troops, Dazhong's defense seemed a little empty. No matter how capable Zhong Hui was, it was a skilled woman who could not cook without rice. She was too embarrassed to set up her defenses.

Zhong Hui was indeed a little worried. Twenty thousand troops were transferred away at once. This cannot be a small number. The entire defense system in the stack had to be rebuilt, but this could not be evenly transferred. After all, some important places cannot be withdrawn by a soldier, so Zhong Hui could only reduce some of the less important or the strongholds behind the flank. As for those key defense passes, they could never move.

Deng Ai naturally knew the mobilization of the troops in Dazhong. Not only were there a large number of Wei spies operating in the direction of Hanzhong, but there were also countless spies conveying information in the Yinping Wudu area, so that Deng Ai could understand the movements of the Shu army in the Yinping Wudu area at a time.

Sima Lun drew 20,000 people at once, which was naturally a good thing for Deng Ai. The defensive power of Dazhong invisibly weakened a lot. When formulating an offensive plan, Deng Ai naturally had to make targeted adjustments.

Dazhong is the core area of ​​the Shu army's defense, so it is naturally stationed in heavy troops. In Deng Ai's march plan, he was not prepared to launch a strong attack on Dazhong. Instead, he ordered Ma Long to lead the Rui Cavalry Battalion and 5,000 garrison troops to encircle the enemy in Dazhong from Gansong west of Dazhong and the Qiang Road east of Dazhong, and adopt the strategy of encircling but not attacking to trap Zhong Hui in Dazhong.

In the roundabout way, the Ruiqi Camp naturally has a clear advantage. Although the terrain in Yinping is mainly mountainous, Dazhong is relatively wider. Otherwise, Jiang Wei would not have chosen to farm here at the beginning, so Deng Ai's task to Ma Long was to drag it to Zhonghui and surround it without attacking.

Deng Ai's real killer move was to send Qian Hong to lead the Zuowei Camp to the south of Qishan Mountain, walk through Konghan Valley, and take Wu Street. Although Zhonghui sent troops to garrison, the troops were relatively small. Most of the 20,000 troops drawn by Sima Lun were drawn from Wu Street and Qiaotou, so relatively speaking, the Wu Street area was relatively empty. Deng Ai ordered Qian Hong to launch a strong attack on Wu Street at all costs, quickly take Wu Street, and then lead his troops to go south immediately and go straight to Yinping Bridge, so that Zhong Hui's retreat could be cut off in one fell swoop.

If we really have to take the bridgehead, Zhong Hui's army will fall into a desperate situation, so Zhong Hui will definitely not sit still and wait for death and send troops to fight with the Wei army for the bridgehead.

However, the terrain on the bridgehead is dangerous. As long as Qian Hong can block the Baishui Canyon one step ahead of time, Zhong Hui will not be able to escape even if he has wings. Then, taking advantage of the panic, the Ruiqi Battalion will launch an attack from the rear wing, and it will definitely wipe Zhong Hui out at Yinping Bridgehead.

As long as Zhong Hui was resolved in the Yinping Qiaotou area, Ma Long and Qian Hong could join forces to seize Baishui Pass eastward, head straight to Jiange, and threaten Chengdu.

And the enemy in Hanzhong will be completely trapped in an isolated and helpless state.
