Zhuge Liang, who is proficient in astronomy, why didn't he calculate the heavy rain that burned the valley above?

In Romance of the Three Kingdoms, when Sima Yi was burned to death in the valley above Zhuge Liang, the weather at that time was also described clearly. It was a cloudless sunny day in Wan Li, and suddenly it rained heavily. And the fire in the valley in front of Zhuge Liang is not the weather. At that time, Wan Li was clear, and it didn't mean to rain at all. But the valley above is sunny and rainy. This also fully proves that people are not as good as heaven. The historical track of the Sima family's establishment of the Jin Dynasty was not changed by Zhuge Liang alone. Because he is a human being after all, Zhuge Liang can't change God's will and historical development. First, the battle of the valley on fire in the history books

During Zhuge Liang's last Northern Expedition in history, Sima Yi knew that Zhuge Liang could not be defeated. Therefore, I have always adhered to the city, and no matter how Zhuge Liang provokes, I can't accept it. Just like the women's dress given by Zhuge Liang in the Romance of the Three Kingdoms, Sima Yi did not shy away from it. In this way, the two armies fought Zhuge Liang for half a year, and Zhuge Liang finally became ill from overwork. Later, he died in Wuzhangyuan. Because the army was big enough to March and fight, and small enough to cook, Zhuge Liang did it himself. Finally, Kongming was exhausted, and Shu was on the road to extinction. Second, the "Romance of the Three Kingdoms" in the valley on fire

In Romance of the Three Kingdoms, Sima Yi did not fight behind closed doors at first. Later, it was learned that the Shu army was in the valley, and Zhuge Liang was also in the valley. He also designed a diversion and dared to go to the valley carefully to burn grain and grass. It can be seen that Sima Yi is extremely afraid of Zhuge Liang. But in the upper reaches of the valley, Sima Yi was caught by Kong. When the fire spread, Sima Yi and his son wept bitterly, thinking that their lives would rest in peace here. I didn't know it was raining on a sunny day, but Sima Yishuai narrowly escaped. Zhuge Liang sighed and fell ill. Third, it means sunny and rainy.

Luo Guanzhong, the author of Romance of the Three Kingdoms, created it from the standpoint of Shu Han. Therefore, the story of Shu Han is also described very reasonably. It is important to know what Liu Bei-ru's benevolence and righteousness are when he occupies Jingzhou and refuses to return it. Another point is that Zhuge Liang was blown too far in Shu Han. As a great counselor, he is inferior to Lu. Sunny rain means that Cao Wei finally won the world, which also paved the way for Sima Jia to establish the Jin Dynasty in history. Zhuge Liang alone cannot change history.
