PS: I'm sorry, I'm going to do birthday for the old man tonight, it's late to update, please understand.

In later generations, even if people who have only read "Romance of the Three Kingdoms", they may not know Fu Luo Dao, Bao Chuan Dao, or even Sanguan Old Dao, but they will not ignore the name "Meridian Valley".

In the ninety-second episode of the romance, "Zhao Zilong slashed five generals Zhuge Liang outwitted the three cities", it is said that Zhuge Liang discussed Cao Wei and gathered the generals to discuss-"Wei Yan went to the account and offered advice: 'Xiahou Nan is a child of anointed Liang, cowardly and unscrupulous. Yan Yuan got 5,000 elite soldiers, took the road out of Baozhong, followed the east of the Qinling Mountains, and threw himself into the north when the Meridian Valley, but in ten days, he could go to Chang'an. If Xiahou heard that a certain sudden arrival, he would inevitably abandon the city and look at the Hengmen Mansion and leave. A certain came from the east, and the prime minister could drive the horses from the valley. In this way, to the west of Xianyang, it can be determined in one fell swoop. ’”

This is the so-called "Meridian Valley Strategy" that has received mixed reviews in later generations, and it is not made up by novelists. "Wei Luo" quoted by Pei Shu in "Wei Yan's Biography", in which the specific details of Wei Yan's strategy are slightly different-

"Wen Xiahou is young, and the son-in-law is also cowardly and unplanned. This holiday, 5,000 elite soldiers, 5,000 grains, straight out of the praise, follow the Qinling Mountains to the east, when the meridian to the north, but ten days to Chang'an. When the news is prolonged, they will flee by boat. In Chang'an, there are only imperial history, Jingzhao is too guarded, and the Hengmen Pavilion and the Valley of the Scattered People are full of food. It is still twenty days before the East is united, and the prince who comes from the valley will be enough to reach it. In this way, it can be determined in one fell swoop to the west of Xianyang. ”

In other words, Wei Yan suggested that at the same time as Zhuge Liang's troops left Qishan, he should lead 5,000 elite soldiers, carrying the necessary rations, to make a surprise attack on Guanzhong through the Meridian Valley. He judged that there were no heavy generals in Chang'an City, and Xiahou Nan not only did not know how to fight, but was also timid, so he would inevitably abandon the city and leave. Then, regardless of whether he can take Chang'an or not, he Wei Yan can take advantage of this chaotic situation and spend more than twenty days in Guanzhong. Then more than a month is long enough, Zhuge Liang's main force must have left Qishan, and he will be in danger of being wiped out. Therefore, "in one fell swoop, the west of Xianyang can be determined".

At that time, Zhuge Liang directly rejected Wei Yan's suggestion, "I thought that this was in danger, it was better to be calm and frank, and I could take Longyou evenly, and I would be safe." It is true that he did not only take the Qishan Road, but "raised his voice to take the road from the Xiegu Road, making Zhao Yun and Deng Zhi suspicious troops, and according to the Keigu", in order to attract and confuse the main force of Cao Wei led by Cao Zhen. However, Zhao Yun immediately repelled Cao Zhen. failed to really play a role in cooperating, Zhang He directly saw through Zhuge Liang's map, and went west along Liupan Valley Road, directly taking the important street pavilion on the side of Qishan, and finally led to the futile return of Cao Wei.

Therefore, for Wei Yanna's "Meridian Valley Strategy", which was not officially implemented, later generations had different opinions, or thought it was a real trick, but it was a pity that Wuhou did not use it. Or think it's pure whimsy, it's normal for Zhuge Liang to refuse to listen. Yeshun himself in the previous life. is more inclined to Wei Yan's plan, and there are three key points:

First, Wei Yan was a general of the Shu Han Dynasty, and he had been guarding Hanzhong for many years, and his understanding of the situation and geographical situation of the enemy and us was not comparable to that of later generations. Plainly. If the soldier comes out of the Meridian Valley and dies without life, unless he is crazy, there is no reason for him to fall into death. Some people also used Cao Zhen's many southern invasions later, and the meridian valley had not completed half of the road in a month to oppose Wei Yan, and the problems all ignored the previous four words "Dao Fenglin rain" - Wei Yan is stupid. It's not enough to count the two-month journey into ten days.

Second, Zhuge Liang's first northern expedition, when Guanlong was empty, Cao Wei focused on the southern line of Eastern Wu, for Shu Han was waiting for him to fend for himself, and he never expected Zhuge Liang to attack boldly. Under this premise, the outstanding surprise soldiers are likely to win by luck - besides, there is only Xiahou Nan in Chang'an, so what is the opponent to worry about?

Third, there has never been a sure way to win military operations, and it is inevitable to take risks, especially when Shu Han is small and big, and if he does not take risks, he will not be able to obtain the greatest benefits, and he cannot completely change the trend of small and large, and the possibility of success is very slim. Therefore, although Wei Yan's plan is in danger, it is not completely impossible to consider, especially his purpose is only to cut off the connection between Guanzhong and Yuluo, so as to wait for Zhuge Liang to go to Long, and he does not have the luxury of hoping that he can achieve a complete victory with only these 5,000 people.

Of course, in the future, there is indeed a loophole in Wei Yan's strategy that is difficult to make up, that is: with Zhuge Liang's cautious personality and marching speed, he may not be able to go to Long and fight against him in more than a month......

The key lies in whether military adventures are necessary and whether there is a certain possibility of success. Just like Deng Ai smuggled into Yinping later, his danger index was really not lower than the "Meridian Valley Strategy", but he won the battle, so he became famous through the ages.

Based on the above reasons, it was the Xunhui who paid more attention to the direction of the Meridian Valley than the contemporaries and military generals, and he believed that the current situation of Shu Han was even more dangerous than the original history of Zhuge Liang's Northern Expedition - one was that Cao Wei had settled Jiangdong and Jiaoguang, and the other was that Nanzhong was still unstable - if they didn't dare to take risks, they would have almost no chance of turning the tables. And Liu Bei's gambling is more than a hundred times stronger than Zhuge Liang......

That's why he proposed, "I'm afraid that this situation is in danger", and suggested that Cao Cao quickly appoint a new governor of Guanzhong, so as not to let the Shu people take advantage of the loophole. But Xiahou Chong disagreed, he said Taiwei, you don't know the geographical situation of the Guanzhong region, the meridian road is very difficult to walk, and even more on the west of Fu Luo, Bao Xie, the Shu army is prominent, it is possible to disrupt our campaign deployment, but it is unlikely to take the meridian road. That's why my father sent the famous generals Zhang He and Xu Huang to the west, and gave way to the road to guard the meridian crossing - the road move is indeed insufficient, but it is not a big problem to deal with the direction that the enemy cannot make a big breakthrough.

Most of the ministers also agreed with what Xiahou Chong said, thinking that Xun was thinking too much, and only Jia Wenhe was silent. Cao Cao asked, "What does Wen He think?" "You have been in Guanzhong for many years, so you should be more familiar with the geographical situation than Shixun, what do you think about this problem?

Jia Xu replied: "Sun Ziyun: 'Therefore, the method of using soldiers, there is no fear that it will not come, and I will wait for it; There is no need to attack, and there is nothing to attack. 'If you think that he should be oblique, in fact, he may not be oblique; If you think that he should not go out of the meridian, in fact, he may not not be out of the meridian. ”

You've thought of everything and blocked it, so what's the enemy fighting for, just surrender. Since they refuse to surrender, and they still want to resist stubbornly or even survive in death, then maybe they will make bad moves, and it is impossible for you to guess them all. Thinking that Dong Zhuo was in chaos, the world was in chaos, Guanzhong's household registration was scattered, and many people fled to Hanzhong through the meridian and other roads, the other party should know better than us whether the road is feasible.

In the end, he concluded: "The minister thinks that the layout of the Zhu State is correct, but the Taiwei's concerns are not unfounded...... and he is not offended by both sides - "I am now three times the pawn and ten times the strength to the Han and Shu, but there is no error, and it must be broken." "Our strength is here now, we don't need to do any tricks, as long as we don't make mistakes, then Liu Bei will die.

The implication is that it is still more inclined to Xun: at this time, even if you find a small loophole, it is better to make up for it as soon as possible, so as not to make a mistake and lose the whole game.

Cao Cao made a decision: "I am suitable for filial piety with my son, and I should go to Chang'an on behalf of the sick." Cao De next to him panicked when he heard it: "The minister is not involved in the matter, dare to be a general?" Please retract your order. Cao Cao glanced at it, oh, you're there, I didn't even see it...... Comforted Cao De at the moment: "Go here and go, but do it according to the plan, the generals can also be unified, there is no need to interfere in the military, I should send those who can use soldiers as the secretary of staff." "Look around at the ministers, and say that you should discuss who to send to assist Cao De and sit in Guanzhong.

The ministers discussed for most of the day, and finally decided on the next three candidates, as Cao De's staff officers, and traveled west together. The first is Cao Zhen, and the second is Xiahou Shang, Xiahou Yuan's nephew, all of whom are the best of the younger generation of Cao Xiahou, and they have all fought - Cao Zhen followed Shixun to conquer Liaodong, Xiahou Shangjiu Zhenbei, and fought with Xianbei and Karasuma many times. Originally, Xun also wanted to recommend Zhuge Liang, but Kong Mingshi was in charge of the military department and could not leave it, so he finally recommended Lu Meng and Lu Ziming.

Lu Meng was originally a powerful general under Sun Quan, and after Sun surrendered, it was Xun who specially summoned this person to the Zhongshu to listen to it. At that time, Xun You was very strange, saying that this is a pure martial artist, if you think he is available, he should also be placed in the army, why was he called to be a scribe? At that time, Shi Xun's answer was: "Before going south, I heard that Lu Ziming was loyal and brave, but he was finally a member of the Sun family, and he should not be allowed to command the army. ”

Lu Zi is really a rough man, but that is the talent tree is temporarily crooked, in fact, the inner endowment can be regarded as the most important. Shi Xun specially summoned him to his command, and later transferred him to the military department and handed him over to Zhuge Liang for training, asking him to read more history books and military books to enrich himself as soon as possible. Lu Meng originally had no intention of surrendering to Cao, but because of the situation, he had to be an ear - he was a member of the Runan Shu clan, if he really went back to his hometown, he would be a small landlord for a lifetime, and he had no way to advance, and if you Sun clan officials all stuck their necks and did not cooperate, would the lord Sun Quan still have good fruits to eat - so you let me take care of things, I will be perfunctory and let me study, then study well.

As a result, after a few years of studying, not only did his ability skyrocket, but even his temperament began to change. It turned out that this person was a pure martial artist, with a rebellious temperament, and belonged to a fiery temper that could swing his fist if he didn't agree with three sentences, and gradually became modest, gentle, and polite, which was really no different from a scribe. Shi Xun occasionally asked Zhuge Liang how Lu Ziming is now? Zhuge Liang replied: "Since studying, I have been self-denying and courteous, and I have the style of a countryman." Yes Xun asked again, can this person be a general? Zhuge Liang replied: "Those who can bravely crown the three armies can be generals, and those who can endure what others can't endure can be handsome." "Now he's more than capable of taking on the task.

So Shi Xun ordered Zhuge Liang to recommend Lü Meng to Xiahoudun, Cao Ren and other generals, thinking that if those people felt that Lü Meng was available, they could restore him to his military position. As a result, after a few earnest conversations, Lu Ziming not only got the respect of the two, but even got on the line with Cao Hong, and Cao Zilian was full of praise for him. So this time, Xiahoudun suggested that Cao Cao send Lü Meng to Cao De as a staff officer, and waited until Shixun proposed this proposal, and since Cao Hong helped him, it was successfully passed.

That night, under the advice of Zhuge Liang, Lu Meng personally came to meet Shixun and said: "Meng has today, all the Taiwei makes it reasonable to teach and read, and if he makes meritorious contributions on the battlefield, he will be the virtue of the Taiwei......" (to be continued......
