Wei Yan took 10,000 recruits to practice his skills in jungle warfare in the deep mountains of Hanzhong County.

In the middle of the year, the imperial court was forced to announce to the world the three major crimes of the Sima family murdering the first emperor, holding the prince hostage, and supporting the army to rebel, and then claimed to deprive the Sima family of all titles and powers, and asked the Sima family to withdraw from Yizhou and come to Luoyang to receive the crime. But these are just to deal with the Jin Kingdom, secretly, Liu Bei still maintains an excellent relationship with the Sima family, and does not do more things that are unfavorable to the Sima family in the court.

After the Jin State released Huangfu Song, Zhang Fei, Jin Xuan, and the imperial army that was captured, detained, and besieged by all walks of life as agreed, the imperial court immediately stopped its verbal and written criticism of the Sima clan in Yizhou, and there were even voices of grievances for the Sima family in the court.

Liu Bei saw very clearly that it was Zhao Xing who posed the greatest threat to the Han royal family, not the Sima family. If Yizhou is lost, then even if he and Cao Cao achieve a political alliance, it will not be able to prevent the various armies belonging to Zhao Xing from descending the Yangtze River and taking Jingzhou directly. Once Jingzhou falls, Jiangdong Sun Jian will immediately take refuge in Zhao Xing, so that only a small piece of territory in the hinterland of the Central Plains can be moved by Liu Bei and Cao Cao.

The Sima family also knew in their hearts that the court shouted loudly this time, but it was forced to be helpless, if they really let Yizhou out, they were afraid that the court would not agree. Although this kind of thing will confuse some people's hearts, as long as you firmly grasp the military power of Yizhou and block Zhao Xing's troops from Jiameng Pass and Baishui Pass, Yizhou is still the territory of the Sima family, and no one will want to grab it for a while.

Sima Yi, who suffered a defeat in the Liang Kingdom, returned to Chengdu and learned from the pain and suggested that his father and eldest brother give him military power, while they made every effort to do a good job in the construction of internal affairs, and the father and son worked together to deal with the huge threat from the Liang State to ensure that the Sima family would not be uprooted.

Although Sima Yi failed this time, both Sima Fang and Sima Lang saw Sima Yi's outstanding talent in military strategy. After some discussion, the Sima family really agreed to hand over the military power to Sima Yi, and appointed Sima Yi as the governor of the soldiers and horses of the Yizhou Fourth Route Army, and was fully responsible for the recruitment and training of soldiers in the future, the appointment and dismissal adjustment of the generals, and the stationing and deployment locations of the various armies, which can be described as full support and cooperation.

After Sima Yi was appointed as the governor of the army and horses, he first made a drastic effort to reorganize and reorganize the existing troops in Yizhou, and adjusted the posts of important generals.

Zhang Ren was appointed as the governor of the North Sichuan Road, and gathered 80,000 soldiers under his command, stationed at the first line of Jiameng Pass in Guanghan County to Yinping Road in Guanghan County, and the military division was Sima Fu, the third son of Sima Fang, and the deputy generals were Wang Ping, Chen Shi, Meng Da and Yang Ren.

Yan Yan was appointed as the governor of the East Sichuan Road, and 60,000 soldiers were gathered under his command, stationed north of Hanchang, and pressed towards Hanzhong County.

Wu Yi was appointed as the governor of the soldiers and horses of the South Sichuan Road, and gathered 60,000 Nanban troops under his command, stationed in the Kunze area of Yizhou County (near present-day Kunming), and the military division was Sima Kui, the fourth son of Sima Fang, and the deputy generals were Zhang Wei, Meng Huo, Wutu Gu and Dong Dana.

Jia Long was appointed as the governor of the West Sichuan Road, and gathered 60,000 Qiang troops under his command to garrison the area of Xixian County, which was a subject of Shu County, with Zhang Song as the military division, and Zhang Yi, Wu Lan, Lu Kai, Yonghong and others as deputy generals.

Sima Yi's major adjustment and reorganization of the Yizhou troops completely exposed the strength of the Sima clan in Yizhou for so many years, and even Zhao Xing couldn't help but take a few breaths after getting this information.

Just to defend the troops in the direction of Liangzhou, Sima Yi mobilized 140,000 troops, and also sent Zhang Ren, Yan Yan, Fa Zheng, and Wang Ping powerful characters. What Zhao Xing didn't expect was that the Sima family obviously had superb means in dealing with foreign races, and they were able to tame the southern barbarians and take the Qiang tribes in the west of Yizhou for their own use.

In the future, if Zhao Xing sent troops to attack Yizhou, he was afraid that Sima Yi would really be able to mobilize a Southern Barbarian army and a Qiang army to support Jiameng Pass and Baishui Pass, and make the Protector Army pay a huge price.

What made Zhao Xing even more troublesome was that intelligence officers reported that south of Baishui Pass and south of Jiameng Pass, large-scale construction of defense facilities by Yizhou officers and soldiers had been discovered. According to the description of the Shadow Members, Zhao Xing felt that the fortifications built by the Yizhou Army this time could be described as sparing no expense and doing everything.

Perhaps inspired by Zhao Yun's approach to building a double-layer city wall to prevent an attack when the Crouching Tiger Army defended Huguan, the fortifications built by the Yizhou Army this time were all fortresses in the shape of a chain of sons and mothers. That is to say, once Zhao Xing mobilized a large army to attack Yizhou, after the troops took a pass with casualties, they would find that there was an equally strong fortress half or a mile away in front of them. What's more, there will be three or four such fortresses blocking the path of the Protector Army's advance.

Sima Yi ordered all the armies to build the fortresses, and uniformly adopted a solid stone wall without leaving a doorway, which he wanted to completely block the road from Yizhou to Liangzhou and Hanzhong. Sima Yi knew that the gunpowder of the Jin State was extremely powerful, and he himself had commanded the troops to personally blow up the walls of Wudu Dao, so he gave this resolute order, and simply did not even leave the opening of the city gate facing the north! Without the door opening, it would be very difficult for the thunder of the Jin Kingdom to blow up the walls of the fortress.

This is just what the shadow team members saw, what Zhao Xing didn't know was that when Sima Yi ordered people to build these defensive passes, he also asked people to seal the black powder produced in Yizhou in a clay pot and bury it under the wall.

For example, in the area of Baishui Pass, where Zhang Ren was stationed, Sima Yi asked an army of 100,000 to build a fortress every mile, and built five roads. Standing on the first pass closest to the original Baishui Pass, the Yizhou army could clearly see the Liangguo army stationed on the old Baishui Pass, and similarly, Cao He and Wang Shuang and others could also see the Yizhou army more clearly through clairvoyance.

Sima Shi would rather block all the northbound roads from Yizhou to Liang and Chang'an, and in the future he would not have any trade with Liang and Jin, and also block Zhao Xing's army in the north of Yizhou. Sima Yi still has a lot of cunning methods that are secretly brewing, and once they are displayed, I don't know how much trouble they will cause to Zhao Xing.
