Gathering troops in the valley? Liu Yin secretly sneered in his heart, although Jiang Wei can be called a military master, but this Hanzhong defense system has a fatal loophole, from the perspective of the subsequent historical process, Zhong Hui besieged Han and Le Ercheng without attacking, and concentrated his forces to attack Yang'an Pass, and the loss of Yang'an Pass led to the final collapse of the entire Hanzhong defense system, Jiang Wei finally had to give up Hanzhong and retreat to the Sword Pavilion.

Jiang Wei has always been heavy on offense and light on defense in the military, and even to attack instead of defending, Hanzhong has not fought for 30 years, and the defense system of Shu has been extremely lax, Jiang Wei changed the strategy of rejecting the enemy outside the country in the past and changed to lure the enemy into the depths, and the strategy of gathering troops in the valley seems to be a simple change in the defense system of Hanzhong, but it is actually far-reaching, and it even determines the final fate of the Shu Han Dynasty.

Hanzhong is of great significance to the whole Yizhou, it is not only the defensive barrier of Yizhou, but also the offensive base of Shu Han to seize the world, when Liu Zhang seized Yizhou in the past, it was because Zhang Lu in Hanzhong made him sleep, and had to borrow troops to reject Zhang Lu, which gave Liu Bei an opportunity. After Liu Bei became the ruler of Xichuan, Fa Zheng also reminded him again and again that Hanzhong is a key place, and he can crusade against national thieves and respect the Han family; , can encroach on Yong, Liang two states, open up the border; Below, you can stick to the key points for a long-lasting plan. Therefore, Liu Bei listened to Fazheng's suggestion and competed with Cao Cao in Hanzhong and conquered it, and this victory also laid the cornerstone of the Shu Han Dynasty, otherwise Liu Bei dared to be the emperor or not, it was another matter.

Zhuge Liang's Jiang Wei's repeated northern expeditions were also based in Hanzhong, and Yizhou was safe for more than 40 years. It is also completely thanks to the solidity of Hanzhong.

In the era of Zhuge Liang's rule. With Zhuge Liang's cautious character. The defense system of Hanzhong has always been watertight, and the Wei State attempted to invade Hanzhong several times, but they were blocked between the lofty mountains and mountains of the Qinling Mountains, and never entered the Hanzhong Plain. After Zhuge Liang's death, Wang Ping continued to use Zhuge Liang's strategy to defeat Cao Shuang, which also proved how correct Zhuge Liang's strategy of defending the enemy outside the country was.

Liu Yin didn't understand why Jiang Wei wanted to sacrifice his strengths and weaknesses. Luring the enemy to go deeper, the strategy of closing the door and beating the dog may be effective, but any military action is also based on strength, Wei is strong and Shu is weak is an indisputable fact, luring the enemy deep is likely to become a wolf into the house, although the Hanzhong Zhuwei is strong, but it is not unbreakable, the layout of the Zhuwei is like a long snake, as long as the Wei army breaks through any point, the situation in the entire Hanzhong will be reversed immediately.

"The general is strategizing. Thinking precisely, this plan to gather troops and gather valleys is indeed unique. However, there is still a question below, the two cities of Han and Le and the dangerous Yang'an Pass are shaped like a long snake, once the Wei army breaks through any city, will Hanzhong not be in danger? ”

The plan to gather troops and gather valleys is a plan that Jiang Wei has considered for a long time, it can be said that Jiang Wei has repeatedly scrutinized every detail of this plan, no matter how big or small, no matter what is calculated, Jiang Wei is extremely proud of this plan, and few people question it, Liu Yin, as an official of Gyeonggi, has never participated in front-line operations, but he dared to question his strategy, which made Jiang Wei very displeased, not to mention Liu Yin's age, he is only in his twenties, a yellow-mouthed son, and dare to talk about the military?

But fortunately, Jiang Wei has a good impression of Liu Yin, yesterday in the court Liu Yin acted decisively and relieved Jiang Wei of the siege, so Jiang Wei did not put his displeasure on his face, but explained to him patiently: "Liu Youcheng has never experienced the front line, I don't know that the mountain road in Hanzhong is steep, our army has repeatedly failed to defeat the Northern Expedition, not lost in the military battle but lost in logistics, the grain and grass are not good, and the baggage is missing, so it can only be used to fight quickly, and the Wei army waits for work at ease, and refuses to resist with high bases and deep trenches. Jiang's plan to gather troops in the valley is the so-called Yi Shi'er, against the Wei southern expedition to Hanzhong, but also to cross the Qinling plank road, the more soldiers in the battle, the greater the supply of grain and grass required, and the difficult burden of plank road transport was thrown to the Wei army, as long as a small group of guerrilla troops were sent in various valley roads, constantly disturbing its grain route, the army entering Hanzhong would inevitably be trapped because of the poor supply of grain and grass. Han Leyang Annai Hanzhong is dangerous, after years of construction, although it is not impregnable, but it is enough to withstand ten times the siege of the enemy, the Wei army came from afar, and it is impossible to carry heavy siege equipment such as trebuchets punching lathes and crossbows, only relying on ants to attack the city, want to take these three fortified cities, it is just wishful thinking. After the Wei army entered Hanzhong, our army only needed to clear the wilderness, and when the enemy's food was exhausted and retreated, our army would pursue it together, would there be no great victory? ”

Liu Yin is no longer able to complain, Jiang Wei has idealized his plan too much, only sees the beneficial side for himself, ignores the negative side, and the cruel facts will eventually prove how wishful thinking Jiang Wei is.

"The general's plan is quite feasible, but if the general goes far away, the defense force of Hanzhong will be extremely limited, and if the Wei army attacks with heavy troops, I am afraid it will not be easy to deal with."

Jiang Wei chuckled and said, "If our army is all concentrated in Hanzhong, how can the anti-Wei dare to attack?" To lure the enemy deeper, it is necessary to make a fuss about this lure. Liu Youcheng is still young, and the art of war still needs to be studied. But I don't know where Liu Youcheng came from, and he became a lieutenant at a young age, and he was terrible in later life. ”

Jiang Wei has been fighting outside all the year round and doesn't know Liu Yin, but it is not difficult to judge from Liu Yin's surname that he should be a disciple of the clan, otherwise he would never be able to become a high-ranking official at such a young age.

Without waiting for Liu Yin to speak, Yin Zheng preemptively said: "Liu Youcheng is the son of King Anping, don't underestimate his youth, the first lieutenant Youcheng cracked the assassination case within ten days, but it was a blockbuster!" ”

"King Anping?" Jiang Wei muttered in a low voice, a sharp cold light suddenly flashed in his eyes, and it was fleeting, and he said indifferently as usual: "Liu Youcheng is visiting today, and he should be accompanied more, but unfortunately he wants to enter the palace today, so he doesn't dare to stay longer. ”

Since Jiang Wei issued an eviction order, Liu Yin had to get up and leave. "That being the case, Yin didn't dare to bother the general anymore and took his leave."

Leaving Jiang's mansion, Liu Yin couldn't help but wonder, although this conversation was not very pleasant, but in general, there was not much disagreement, Jiang Wei's sudden change of attitude made Liu Yin a little caught off guard and inexplicable.

Why is this happening?
