I think Zhuge Liang went out to Qishan six times under the banner of "recovering the Central Plains and reviving the Han Dynasty" in order to realize Liu Bei's last wish. To achieve this goal, the only way is to bring down Cao Cao and seize the Central Plains. To realize the strategy of recovering the Central Plains, the only tactic is to March straight into Chang 'an, even if it is a circuitous tactic, the ultimate goal should be to break through Chang 'an. However, Zhuge Liang made five northern expeditions, took the southeast of Gansu three times, and crossed the Qinling Mountains and Weibin twice by the scattered pass and the praise ramp. So transporting troops is simply a matter of seeking fish from the wood, which runs counter to the goal of breaking Chang 'an and painting the Central Plains. Let's see what he did during the Northern Expedition. First, do everything possible to go to Liangzhou to win horses. Second, he cut wheat like a thief in central Gansu. According to Zhuge Liang's explanation, it is to obtain food. In this way, I wandered around for several years, and basically didn't touch a hair on Cao Wei except for the cost of losing troops and getting insignificant extra money.

If we really want to plot the Central Plains, we should go out of the Meridian Valley to Chang 'an according to Wei Yan's clever plan. Later generations of "wise after the event" all said so. If we want to solve the salary problem, isn't Guanzhong richer than Liangzhou and Longzhong? Why do we need to plunder the barren land on the dragon? But the problem is that Zhuge Liang just didn't listen to Wei Yan's suggestion and thought his plan was too risky. In fact, sometimes a little adventurous spirit is needed in the military, otherwise, how can we make a surprise victory without fail? When it comes to adventure, Zhuge Liang himself can be called "the master of adventure". In those days, Battle of Red Cliffs was a masterpiece of adventure. But it is the same Zhuge Liang who used to be a "master of adventure", but now he has become a "master of caution". Caution is of course necessary, but being too cautious is tantamount to standing still. What year will it take to overthrow Cao Wei? Didn't you see that the commander in chief of Guanzhong was Xia Houdun, far from Wei Yan's opponent? If we had seized the opportunity at that time, we would have killed him by surprise, and Chang 'an was at your fingertips. Now times have changed, and the Shoujiang has already been replaced by Sima. Who is it, let alone Wei Yan's tricks, even Zhuge Liang can't stand him!

In fact, from another angle, Zhuge Liang can't attack the enemy. Isn't this what the two emperors of Shu Han dreamed of?

Judging from the author's villain's heart, Zhuge Liang, who is far-sighted, doesn't want to win at all. The so-called restoration of the Central Plains and the revival of the Han Dynasty is just a beautiful deceptive slogan, not a real goal. Because Zhuge Liang's two masters, the old and the new, are not selfless "living Lei Feng", and they are bent on taking back the land of the Han family from Cao Shi's father and son, and then taking back the nominal Han Xian emperor with both hands. They just want to be safe from the heart. Not only did they not want to destroy Cao Wei, but they even reached a tacit understanding with Cao Wei. Because only by letting Cao Shi and his son hold the soft-hearted Xian Di in their hands forever can the father and son feel at ease to be his Emperor of Shu. If Cao Wei was destroyed and the Central Plains was restored, wouldn't we welcome Emperor Xian back and be his big fellow emperor? At that time, neither uncle nor brother could compare with the benefits of the emperor himself. If Liu Bei, Liu Chan and Zhuge Liang spent most of their lives fighting for the world with their heads held high, but only doing good deeds like Lei Feng, wouldn't it be so noble as to be puzzling?

Although Cao He fought fiercely, he had tacitly agreed to cooperate with each other as emperor. I think when Liu Bei defected to Cao Cao, they were "childhood friends" heroes, and later they became a secret alliance to muzzle the Han family. Later, Guan Yu, a close friend of his uncle, was not killed, but was captured by Cao Cao, because Cao Liu had the same interests in his bones, so he needed to leave personal feelings for later use. Sure enough, when he arrived in Battle of Red Cliffs, Cao Cao fled to Huarong Road and performed a trick of "catching and releasing Cao Cao" in order to repay his kindness and carry out Liu Bei's secret will. In order to hide people's eyes and ears, Zhuge Liang also solemnly "watched the sky at night" and concocted the saying that "the sky will not destroy Cao" to deceive the world.

A clever man like Zhuge Liang naturally knows the thoughts of Liu and his son. You see, when he first published Longzhong Dui, he talked about all the waiting words in the world and planned two-thirds of the plans. Speaking of the recovery of the Central Plains and the revival of the Han Dynasty, he came to an abrupt end and didn't want to say anything more. Therefore, establishing Liu as emperor is the goal. The prosperity of the Han Dynasty in the Central Plains was a great cover to win people's hearts. In order to carry out this established policy, Zhuge Liang specially arranged Guan Yu and Cao Cao to perform a double-reed play of "catching and releasing Cao Cao". If Wei Yan's idiot is sent to Huarong Road, Cao Cao will be killed at once, and the deployment of Liu Bei and Zhuge Liang will be disrupted at once. It can be said that this is the collective deception of Shu Han monarchs and their subjects, but they only deceived the children of Soochow and Zhou Yu. Later, Zhuge Liang sent troops to the Northern Expedition several times, which was called the capture of the Central Plains. In fact, he is just beating around the bush in a remote place far away from Chang 'an, but he is just acting for the world. From this point of view, Zhuge Liang is really the best man in the world, that is, he has gained the tangible benefits of sealing his wife and covering his children, and won the reputation of the first sage in the ages. Even the ancient Guan Zhong and Le Yi can't compare with Zhuge Liang!
