The last three kingdoms

Chapter 70
Gathering troops and gathering valleys?Liu Yin sneered secretly in his heart. Although Jiang Wei can be called a military master, this Hanzhong defense system has a fatal loophole. From the follow-up historical process, Zhong will besiege the two cities of Han and Le instead. Attack, concentrated forces to attack Yang'an Pass, and the fall of Yang'an Pass led to the final collapse of the defense system of the entire Hanzhong. Jiang Wei finally had to abandon Hanzhong and retreat to Jiange.

Jiang Wei has always focused on offense and despise defense in the military, even using offense instead of defense. The 30 years of no war in Hanzhong has also made Shu's defense system extremely lax. The strategy of deepening the enemy and gathering troops in the valley may seem like a simple change in Hanzhong's defense system, but in fact it had far-reaching effects, and it even determined the final fate of the Shuhan Dynasty.

Hanzhong is of great significance to the entire Yizhou. It is not only the defensive barrier of Yizhou, but also the offensive base for the Shu Han to seize the world. When Liu Zhang separated Yizhou in the past, it was because Zhang Lu made him sleepless in Hanzhong Not borrowing troops to reject Zhang Lu, the result gave Liu Bei an opportunity.After Liu Bei entered Xichuan, Fazheng also reminded him again and again that Hanzhong is the key point. Up, you can crusade against national thieves and respect the Han Dynasty; plan.That's why Liu Bei followed Fazheng's advice and competed with Cao Cao in Hanzhong and defeated him. This victory also laid the cornerstone of the Shuhan Dynasty. Otherwise, whether Liu Bei dared to become emperor is another matter.

Zhuge Liang's Jiang Wei's repeated Northern Expeditions were also based in Hanzhong, and the peace of Yizhou for more than 40 years was entirely due to the impregnability of Hanzhong.

In the era when Zhuge Liang was in power, with Zhuge Liang's cautious character, Hanzhong's defense system has always been watertight. Wei Guo tried to invade Hanzhong several times, but was blocked between the mountains of Qinling, and never entered the Hanzhong Plain.After Zhuge Liang's death, Wang Pingyan used 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 used his strengths to make use of his weaknesses to lure the enemy deep. The strategy of closing the door and beating dogs may be effective, but any military action is also based on strength. It is an indisputable fact that Wei is strong and Shu is weak. It may become a way to lure wolves into the house. Although the siege of Hanzhong is strong, it is not indestructible. The siege is arranged like a long snake. As long as the Wei army breaks through any point, the situation in Hanzhong will immediately reverse.

"The general strategizes and thinks carefully. This strategy of gathering troops and gathering valleys is indeed unique. However, I still have a doubt. The siege of the two cities of Han and Le and the narrow pass of Yang'an Pass is like a long snake. Once the Wei army breaks through any City, isn't Hanzhong in danger?"

The strategy of gathering troops and gathering valleys is a plan that Jiang Wei has considered for a long time. It can be said that Jiang Wei has repeatedly considered every detail of this plan. Few people questioned that Liu Yin, as an official in Gyeonggi, had never participated in front-line combat, but he dared to question his strategy, which made Jiang Wei very unhappy, not to mention Liu Yin's age, he was only in his 20s. How dare a yellow-mouthed child talk about military affairs?

Fortunately, Jiang Wei has a good impression of Liu Yin. Liu Yin acted decisively in the court yesterday and helped Jiang Wei out of the siege, so Jiang Wei did not show his displeasure on his face, but patiently explained to him Said: "Liu Youcheng has never been to the front line, and he doesn't know the steepness of the mountains in Hanzhong. Our army has repeatedly failed in the northern expedition. It is not because of the military battle but because of the logistics. The food and grass are not enough, and the luggage is lacking. We can only use quick battles, and the Wei army is waiting for work. High fortifications and deep moats resist each other, so in the 40 years since Marquis Wu conquered Wei, although he has won a small victory, he has not gained an inch of land. Jiang’s plan to gather troops and gather valleys is just like the so-called Yi Shier. He conquered Hanzhong in the south against Wei and also crossed the plank road in Qinling Mountains Therefore, the more soldiers marching, the greater the supply of food, grass, and supplies needed, and the burden of difficult transportation on the plank road was thrown to the Wei army. The army entering Hanzhong must be trapped due to insufficient supply of food and grass. Han Leyang An is a dangerous pass in Hanzhong. After many years of construction, although it is not impregnable, it can withstand ten times the enemy's siege. Catapults, lathes, crossbows and other heavy siege equipment rely on ants to attack the city. It is wishful thinking to take these three fortified cities. After the Wei army entered Hanzhong, our army only needed to fortify the walls and clear the fields. At the same time, if our army join forces to pursue it, will there be no great victory?"

Liu Yin was already powerless to complain anymore, Jiang Wei had overly idealized his plan, only saw the good side and ignored the bad side, and the cruel facts would prove Jiang Wei's wishful thinking in the end.

"The general's plan is quite feasible, but if the general goes far away, Hanzhong's defensive power will be extremely limited. If the Wei army invades heavily, it may not be easy to deal with."

Jiang Wei chuckled and said: "If all our troops are concentrated in Hanzhong, how dare the rebellious Wei invade? To lure the enemy to go deep, we must make a fuss about this lure. Liu Youcheng is still young, and the way of war is not yet true. It takes more study. But I don’t know where Liu Youcheng came from, and he became a lieutenant Youcheng at a young age, and he is a formidable young man.”

Jiang Wei has been fighting abroad all year round and does not know Liu Yin, but it is not difficult to judge from Liu Yin's surname that he should be a son of the clan, otherwise he would not be able to rank among high officials at such a young age.

Before Liu Yin could open his mouth, he said in advance: "Liu Youcheng is the son of Anping's mourning king. Don't underestimate him as a young general. Youcheng, the first lieutenant, solved the assassination case within ten days, and he became a blockbuster. !"

"King Anping?" Jiang Wei murmured, a sharp cold light flashed in his eyes, it was fleeting, and he said indifferently as usual: "Liu Youcheng is visiting today, so I should accompany a certain book, but unfortunately I have to enter today. Gongmiansheng, I don’t dare to keep You Cheng any longer, Jiang will definitely host a banquet for You Cheng in another day, so I won’t get drunk.”

Now that Jiang Wei issued the order to chase away the guests, Liu Yin had no choice but to get up and leave. "Since that's the case, Yin doesn't dare to bother the general anymore, so I leave."

Leaving the Jiang Mansion, Liu Yin couldn't help but wondered. Although the conversation this time was not very pleasant, in general, there was not much disagreement. The sudden change of Jiang Wei's attitude made Liu Yin Some were caught off guard and inexplicable.

Why is this happening?

Jiang Wei's sharp gaze after hearing the name of King Anping—no, it is more accurate to say that there was a murderous intent in his eyes—although it was short-lived, Liu Yin was so keen that any slight change in Jiang Wei's demeanor would not matter. Never escaped his eyes.

Could it be that Jiang Wei had a grudge against his deceased father?
Liu Yin really doesn't know, but he has some doubts about Jiang Wei's mind. Even so, Liu Li has passed away, and the deceased is dead. What kind of festival still needs to be hated?

The Shuhan building is about to collapse. At this most critical moment, Jiang Wei, who is the pillar, does not accept his faithful advice, and the Shuhan is really in danger!
