#Wei Yan's Meridian Valley Conspiracy has no chance of success#
The probability of wei Yan's meridian valley plot succeeding is very small.
1. In military operations, it is necessary to know oneself and know the other, Wei Yan spoke on the basis of no investigation, he was not very clear about the topography of the Meridian Valley, only that the Meridian Valley was very close. Let's just say that Xiahou Shu, who is guarding Chang'an, is mentally retarded, but what about Cao Zhen!? The historical Cao Zhen is not as mentally retarded as written in the Romance of the Three Kingdoms, but is the commander of the three armies higher than Zhuge Liang's ability.
2. Whether the Meridian Valley Wei Yan can pass smoothly, let's leave it alone, look at the achievements of others, the former Han Xin abandoned halfway, Han Xin bing dumped Wei Yan a few streets, or choose Chen CangDao, the future Gao Yingxiang Meridian Valley was completely destroyed. As well as the Xi'an Incident, Wang Yaowu rushed to Xi'an halfway and abandoned, Wei Yan estimated that he was not much smarter than these historical military experts.
3. Even if Wei Yan led five thousand troops to Attack Chang'an, did Zhuge Liang rush from Longyou to Chang'an? The actual situation proved that Zhuge Liang could not reach Chang'an, and he could not form a pinch attack, and he broke into the sand at the street pavilion. I had to return to Hanzhong, and the coordination work was not done well. If Wei Yan rushed to Chang'an, Zhuge Liang would definitely not be able to go from Longyou, even if Xiahou Shu of Chang'an had no combat effectiveness, as long as he closed the door and held on for seven days, Cao Zhen sent his troops to Luoyang, with the strength of the State of Wei, Cao Zhen dispatched thirty thousand troops, and there would certainly be no problem in dispatching thirty thousand troops, and he would definitely be able to arrive in a week, luoyang to Chang'an all the way flat, Wei Yan from the Meridian Valley to the mountains. Even if Chang'an was at the end of the crossbow, once Cao Zhen arrived under Chang'an City, with a thirty thousand troops, against Wei Yan's five thousand tired divisions, it would definitely be a hanging blow, and the Xiahou horses in the city were also rushing out, and Wei Yan might be completely annihilated.
Therefore, the possibility of wei Yan's Meridian Valley plot succeeding is very weak, without knowing the geography and the military deployment of the other side, and Zhuge Liang is not a military attack, even if it is possible to be surrounded by Cao Zhen and annihilated by Cao Zhen when it reaches Chang'an.
Therefore, Wei Yan's Meridian Valley conspiracy was demonstrated by posterity, and some people said that it was possible, but the opportunity was delayed, and according to the actual situation at that time and the examples of later generations, it should be that the probability of success was very small. Zhuge Liang's non-adoption was certainly fully considered, and Zhuge did more than Wei Yan did things more thoroughly.
