Why did Zhuge Liang surround Sima Yi to death? Is it really because of the rain that he didn't kill him?

Actually, it's not, because Zhuge Liang felt that it was raining heavily at this time and God was helping Sima Yi, so he felt very disappointed and felt that the destiny could not be violated, so he didn't continue to kill Sima Yi. Although Zhuge Liang is extremely clever, he is also a man who believes in heaven.

Zhuge Liang thought his plan should be perfect this time, but it rained at the last critical moment. Zhuge Liang's specialty is observing astronomical phenomena. He can observe the weather changes and many natural phenomena from the astronomical phenomena, which is his outstanding point.

But he is not good at physics. What he never expected was that the air over Hulu Valley would expand rapidly because of the explosion of mines. When air is heated and rises, it will accelerate the air flow.

The air outside the valley is very humid. When it meets the dry air in the valley, the two air streams will form water droplets, and the more water droplets accumulate, it will become a rainstorm.

Zhuge Liang could not explain it scientifically, so he thought that God was helping Sima Yi. He began to doubt his behavior. Is this against his fate? Is it because God doesn't want to destroy Cao?

Therefore, Zhuge Liang began to feel depressed and felt that the destiny could not be violated. If you go against the sky, you will be damned. So he became afraid and decided to let Sima Yi go and stop chasing him.

But now that we know the truth, we can also explain it through science. But people at that time could not know that people at that time were all in awe of ghosts and gods. It is not surprising that Zhuge Liang spared Sima Yi.
