Romance of the Three Kingdoms
He was created for the novel in order to flesh-out the story of Zhuge Liang's Southern Campaign. Mulu was known as a very intimidating man, able to use magic to summon rainstorms, along with the ability to control animals in battle against Shu. Mulu ran into battle atop an elephant. When the wits of Zhuge Liang proved greater than his own, he was ultimately killed.
