When Zhuge Liang went south, who used witchcraft to make the Shu army into a bitter battle?

During Zhuge Liang's southern expedition, King Mulu used witchcraft to make the Shu army into a bitter battle.

King Muru is the owner of Banan Cave and an ally of Meng Huo. Being good at magic can change the weather, control animals and command them to fight. With the help of the magic weapon, he initially won some victories over the Shu army, but after Zhuge Liang's fire-breathing wooden beast scared away his animals, he was defeated and finally died in the disorderly army.

King Muru led the soldiers out of this cave with wild animals. Zhao Yun and Wei Yan heard that the barbarians were going out, so the generals went into battle. Standing side by side in front of the front line, the two generals saw different flags and equipment of barbarians: many people were naked and ugly; With four sharp knives; In the army, drums and horns don't ring, and the screen gold is the number; King Muru came out of the banner, wearing two treasure knives around his waist, holding a clock and a white elephant. When Zhao Yun saw this, he said to Wei Yan, "I have never seen such a figure in my life." While they were meditating, they saw King Muru chanting and shaking the clock. Suddenly the wind blew hard, flying sand and stones, like a shower; At the sound of the horn, tigers, leopards, wolves, poisonous snakes and wild animals jumped out of the wind, bared their teeth and rushed over. How did the Shu soldiers arrive? They retreated. Barbarian soldiers then chased and rushed straight back to Sanjiang Street Road. Zhao Yun and Wei Yan gathered the defeated troops and came to Zhuge Liang's tent to confess their sins and explain in detail what had happened.
