During the Three Kingdoms period, with the help of Zhuge Liang, Liu Bei was able to form a three-legged power with Sun Cao, establish the Shu Han regime, and establish himself as emperor. Later, Liu Bei died of grief over the defeat of Yiling, and on his deathbed, he entrusted all the power of the state to Zhuge Liang, hoping that he could complete his unfinished business, unify the Central Plains, and return the world to the Han Dynasty.
After Zhuge Liang seized power, he exerted great efforts to govern, and under his efforts, the national strength of the Shu Han gradually became stronger. At this time, Zhuge Liang was grateful for Liu Bei's kindness, and always regarded Liu Bei's unfinished career before his death as his only goal in life- that is, the Northern Expedition to fix the Central Plains. Therefore, he wrote down the "Table of Renunciation" that has been passed down through the ages to express his firm will to the Northern Expedition.
However, in the whole process of the Northern Expedition to Cao Wei, Zhuge Liang encountered one of the strongest opponents in his life, Sima Yi, Zhuge Liang was a cautious and cautious person in his life, and he knew that Sima Yi was extremely good at military affairs and had excellent strategy, so he used a divisive strategy to make Emperor Wei alienate Sima Yi and not use Sima Yi. Although the initial results were achieved, there was no Sima Yi behind, and Cao Wei's attacks on Zhuge Liang were almost all inferior, coupled with the death of the general Cao Zhen, there was no one on the Cao Wei side who could match Zhuge Liang, so Emperor Wei recruited Sima Yi again and worshiped him as commander to meet Zhuge Liang.
At this point, Zhuge Liang and Sima Yi, the doomed enemy, began a series of battles of wits and courage, and the competition between Zhuge Liang and Sima Yi has also become a history that many history lovers talk about. In the end, after a hard battle between the two sides, Zhuge Liang finally found a once-in-a-lifetime fighter to completely eliminate Sima Yi, which is also known as the "Battle of the Upper Valley". It is said that Zhuge Liang led Sima Yi's army into the upper valley, and sealed the passages of the upper valley, using Zhuge Liang's usual fire attack to deal with Sima Yi, because the passage of the upper valley was narrow, and the intersection was sealed by Shu soldiers, Sima Yi's army was like a lamb to be slaughtered in the upper valley, and there was nothing to do. I had to watch the Wei generals being besieged by fire, and finally felt that they were doomed, so they raised their swords to think about ending their lives, who knew that at this time, it rained heavily and extinguished the fire, Sima Yi saw this and immediately made a quick judgment, the army immediately withdrew from the upper valley, and the Wei army also escaped from death.
However, Shu Bing had obviously sealed Taniguchi? Even if the fire had been extinguished, the Wei army was already a bird of fright, and its combat effectiveness was definitely extremely low. At this time, as long as the Shu soldiers came out to intercept the intersection, Sima Yi still could not run away. Why did he let Sima Yi run away? Why didn't Zhuge Liang go after sima yi? Miss this once-in-a-lifetime opportunity?
In fact, the reason is very simple, we know that Zhuge Liang knows astronomy and geography, and is also extremely proficient in numerology, everyone knows that the master of xiangshu is a very strange profession, they count people never count themselves, this kind of person seems to have the destiny of heaven, and everything they do is as if they are carrying out the mission sent to him by heaven in the human world, otherwise they will be punished by heaven. Zhuge Liang is the same, he is a person who believes in the Mandate of Heaven extremely, when Huarong Dao let Cao Cao go, it was also because he calculated that Cao Cao's life was not exhausted and could not be violated, so he let Guan Yu go to Guard Huarong Dao (because he knew that Guan Yu Zhongyi would definitely let Cao Cao go, and he could also let Guan Yu repay Cao Cao's kindness, and when he saw Cao Cao again in the future, they would not owe each other and could let go and kill). This time when Sima Yi was released, he also calculated that Sima Yi's life number was not exhausted, and Cao Wei's life number was not exhausted, and he did not dare to violate Providence, so he finally lost to Providence, let Sima Yi go, and let his life come to an end after this battle.
Therefore, we should not believe in fate too much, my fate is up to me, if Zhuge Liang believes in his fate, he should not go north, but sooner or later the Shu Han regime will not last long, but he also feels that Liu Beizhi's grace has to realize the so-called "unification of the world", Zhuge Liang is constantly struggling in this extremely complex and contradictory psychological environment. After all, he still had to believe in his fate. In fact, Zhuge Liang is also a tragic figure in history.
