When Zhuge Liang burned Sima Yi on fire in Shangfang Valley, why did it suddenly rain heavily?

Zhuge Liang of the Three Kingdoms is famous for his resourcefulness and many strategies. Because he knows everything and can even control the wind and rain, he is known as the "demon". For thousands of years, Zhuge Liang has become a symbol of wisdom in people's minds.

The most powerful and effective tactic used by Zhuge Liang is two words: fire attack.

The first thing Zhuge Liang did when Liu Bei visited the thatched cottage and invited him down the mountain was to prove himself. To this end, he lit a fire - Burning Bowang Slope.

Faced with the powerful and aggressive Wei army, Zhuge Liang avoided direct confrontation with them. Instead, he used decoy tactics to lead the Wei army led by Xiahou Dun into an ambush circle. Finally, he lit a prepared fire and burned it to the ground. Wei Jun cried for his father and mother and was completely defeated.

This move made Zhuge Liang famous. From then on, Guan, Zhang and Zhao who were not convinced by him all obeyed him.

After that, Zhuge Liang lit another fire in Xinye, allowing Cao Cao's general Cao Ren to escape in embarrassment, allowing Liu Bei to survive the crisis and usher in a turning point.

In the Battle of Chibi, Zhuge Liang and Zhou Yu jointly planned a fire attack plan that was exquisite. In the end, the fire burned Cao Cao, cutting off his beard and abandoning his robes, and fled in embarrassment. He was reborn in the fire, and the pattern of "three parts of the world" This was established.

After Liu Bei died of illness in Baidi City, Zhuge Liang used a fire to burn the invulnerable Tengjia soldiers in the process of pacifying the Southern Yi, thus making the rear of the Shu Kingdom impregnable and solving the worries for the Northern Expedition.

Of course, if the first four fires can be called Zhuge Liang's classics, then the fifth fire has become Zhuge Liang's rare work.

During the Northern Expedition, Zhuge Liang never succeeded. In addition to various external factors, he also encountered a powerful enemy-Sima Yi.

Sima Yi's strategy is obviously different from Zhuge Liang's. For this reason, he adopts the method of staying unchanged to cope with the ever-changing situation, and has always insisted on not going into battle.

Zhuge Liang and Sima Yi faced off at the Weishui River. This time, Zhuge Liang adopted a series of tricks to make Sima Yi take the bait. Sima Yi believed that the upper valley must be the "granary" of the Shu army. In order to destroy the Shu army's food road, He decided to deliver a full blow.

The entrance to the upper valley is narrow, the hinterland is wide, the sides are high, and the middle is low. It is shaped like a gourd, but the entrance can only pass through for one person and one rider. Sima Yi knew he had been deceived when he entered the valley, but it was too late. When Zhuge Liang's fire burned in the Shangfang Valley, Sima Yi lamented that all three of his father and son would die here, and couldn't help but burst into tears.
