Nearly 100,000 troops were massed in northern Yizhou. There is no doubt that the movement is very large, and it is almost impossible to completely conceal your whereabouts and not let outsiders know.

When Sima Yi learned that the Kunlun Army, the Tianyi Army and the Blue Wolf Army had arrived in Liangguo one after another, he didn't feel how to panic in his heart, the 100,000 army was indeed very scary for ordinary forces, but for the vast Yizhou, it was really not enough. The key is that there are only a few roads from the north into Shu, all of which are rugged and difficult, as long as a small number of troops are stationed to defend, the 100,000 troops of the attacking side can be blocked at the pass.

Although the Protector Army is equipped with advanced firearms, Yizhou now also has gunpowder equipment troops, not to mention that Sima Yi also let people build passes and fortresses without leaving doors, and let people bury a lot of gunpowder under the pass, as long as the Jin army comes to attack, they will suffer a fierce counterattack.

In the face of such a strong and dangerous defensive facility, all conspiracies and tricks are difficult to work, unless there is a major change in Yizhou, otherwise there will be no ten years and eight years, and the army of the Jin State will not want to march into the Yizhou Plain. The problem is that with ten years and eight years of time elapsed, the Jin State has already been dragged into the quagmire of decay, and the central court will not miss the opportunity to watch the Jin State and Yizhou consume each other and be indifferent.

What really annoyed Sima Yi was actually Jia Xu's revelation in the "Jin Bao" that he intended to spread the plague to the Xiliang region, and the fact that the troops attacking Jingzhou actually suffered a big loss in Yiling, and they have not been able to take the land of Nanjun until now.

Jia Xu's article does not seem to have hurt a single soldier in Yizhou, but it has a long-term adverse impact on the entire situation in Yizhou.

Jia Xu's hand, first of all, provided Zhao Xing with the most favorable excuse to make a move to Yizhou, allowing Zhao Xing to occupy the moral high ground. In this era, the army has always been about a division to be famous, and there is no way to fight with a way. Yizhou's repeated offenses against Liangguo have already made the people of Liangguo very hateful, and now the big crime of spreading the plague has been added, which is enough for Zhao Xing's forces to wipe out Yizhou three times.

In addition to giving people authority, Jia Xu's articles also had an impact on many generals within the Yizhou system. Although Zhang Ren, Yan Yan and other local generals in Yizhou didn't say anything, it is unknown what they thought in their hearts. The huge influence of "Jin Bao" is far from being comparable to "Yizhou News", in the face of many solid evidence, even if Sima Yi is clever and moves flowers and trees, he is only deceiving ordinary people, and resourceful people like Zhang Ren and Yan Yan are easy to be fooled?

Although the hidden adverse effects have been caused, they are still under control, and Sima Yi feels that he still has a chance to bring the unfavorable situation back. What made him speechless the most was that Wu Yi and Jia Long had a total of 110,000 people, while the Jingzhou Huangzhong troops who defended Yiling were only 30,000 people. In the case of occupying such an advantage, Wu Yi and Jia Long actually let Huang Zhong take back the Jingmen Mountain position that had already been obtained, and this Huang Zhong really surprised **.

Although the external situation began to be unfavorable to Yizhou for a while, Sima Yi still sat firmly in Diaoyutai, with a posture of soldiers coming to block and water to cover the earth, and did not show the embarrassment of being in a hurry, blocking left and right.

Sima Yi first sent a secret envoy to Luoyang to meet Cao Cao and Liu Bei, asking the imperial court to increase its support for Yizhou, and at the same time to increase pressure on Jingzhou to force Liu Biao to submit as soon as possible. Then, he appointed Zhang Ren as the marshal of the Yizhou East Route Army, and went to Yiling to supervise and command Wu Yi and Jia Long to fight, while he himself took the post of marshal of the Yizhou North Route Army, and collected Zhang Ren's troops and Yan Yan's troops under his account without a trace.

Although Sima Yi had no evidence to doubt Zhang Ren's loyalty, in the current situation, it was undoubtedly the safest way to transfer Zhang Ren to the eastern part of Yizhou to be responsible for attacking Jingzhou. Zhang Ren was originally the governor of the soldiers and horses of the North Sichuan Road, and there were 80,000 soldiers with armor under his account, and he went to Yiling not only did not reduce his position, but he was promoted to one level, becoming a marshal of the same level as Sima Yi, and the number of soldiers and horses under his command was also tens of thousands. Such an arrangement will not make Zhang Ren feel cold, but also reassure the Sima family, which is really a lot of win.

Sima Yi had an in-depth analysis of Zhao Xing's possible route to attack Shu, and he was originally worried that Zhao Xing would send a detachment of partial divisions to make a detour to the snowy plateau and raid Yizhou from Tang Xuan's territory, so he did not take the western part of Yizhou lightly for a moment. Now, judging from the news sent back by the spies in Liangguo, Zhao Xing has no such plan, and it is estimated that he was also frightened by the harsh environment of the snowy plateau.

As for Zhao Xing's secret support for Liu Biao, it was already expected by Sima Yi. Although Zhao Xing's support will bring trouble to Yizhou, such as the current Yiling War, which has become a little stalemate because Liu Biao has Zhao Xing's support, this is not a fundamental problem. As long as Yizhou, Wuzhou and the imperial court continue to put pressure on Jingzhou, Liu Biao will be unable to hold on sooner or later, and Yizhou will be able to get a piece of the pie at that time.

Now that Zhao Xing's front and rear hands had been expected, Sima Yi had nothing to worry about, and he was now eager to see what the Shu attack army, which had been assembled in Hanzhong and Wudu, could shake the fortifications that he had painstakingly operated in northern Yizhou for several years.

As if to prove Sima Yi's analysis and judgment, soon after, the vanguard army under the leadership of Zhang He went out of Baishui Pass and went down the Western Han River, encountering fierce counterattacks along the way, and after paying a heavy price, it only advanced ten miles forward. According to the attrition situation of the vanguard army, if they do not wait for them to attack below the Jiameng Pass, I am afraid that they will exhaust the 60,000 troops.

The Kunlun army, another way to attack Shu, entered the Minshan from the upper valley of Wudu County, and tried to go down the Minjiang River only to Chengdu, but it was already recognized by Sima Yi, and just out of the Minshan, it was sniped by Wang Ping and Yang Ren's 40,000 troops guarding the city in the Maoqi Road. In a panic, Xu Rong, the commander of the Kunlun army, had to fight and retreat, and hid in the Minshan Mountain behind him with the army, and no longer had the arrogance at the beginning.

Zhao Xing's assembled attack troops left the Blue Wolf Army and the Tianyi Army did not participate in the battle, but Sima Yi believed that the Blue Wolf Army would not directly participate in the battle in this battle, but only contained the Huangfu Song troops in the Chang'an region in the territory of Liangguo. No matter how good the blue wolf army is, it is a cavalry unit after all, and entering Yizhou, which is high in mountains and dense forests, will not only fail to play a role, but will also increase the pressure on logistics and transportation.

What really made Sima Yi uncertain was this "Tianyi Army" that appeared out of thin air, since this army arrived in Hanzhong, it has been silently staying at the station, and there has been no movement, which makes people feel strange.

However, it has always been a dog that can bark and does not bite, and a dog that bites does not bark, Sima Yi did not dare to despise this army that did not move.
