King Mulu

Here is the exhaustive biography of King Mulu (木鹿大王) (? – 225), the fictional lord of Bana Cave (八納洞) and a powerful sorcerer-king of the Nanman, incorporating the narrative of Romance of the Three Kingdoms. He has no historical existence.

Historical Status

King Mulu does not appear in any historical source. Like King Duosi, Jinhuan Sanjie, Wutugu and the other colourful Nanman chiefs of the southern campaign, he is a pure invention of Luo Guanzhong’s novel, created to heighten the exotic and magical atmosphere of Zhuge Liang’s expedition of 225.

Romance of the Three Kingdoms Portrayal

In Chapter 90, after Meng Huo’s successive defeats, his brother-in-law Dai Lai (Brought Cave Chief / 帶來洞主) recommends seeking aid from King Mulu of Bana Cave. Mulu is described as a master of sorcery who rides a white elephant, can summon wind and rain, and is always accompanied by tigers, leopards, wolves, venomous snakes and scorpions; he commands thirty thousand “divine soldiers.” Meng Huo sends gifts and a letter; Mulu arrives mounted on his elephant, wearing gold-and-pearl ornaments and carrying two great swords, and promises to avenge the Nanman king.

In the first engagement Mulu’s beasts and storms drive back Zhao Yun and Wei Yan. Zhuge Liang, however, prepares wooden mechanical beasts that belch fire and smoke. When the two armies meet again, Mulu shakes his bell and chants; the wild animals charge—only to panic at the sight and smell of the fire-breathing contraptions. Chaos engulfs the Nanman ranks. Mulu is thrown from his elephant and trampled to death in the stampede. With their sorcerer-king dead, the Shu army overruns the cave and captures Meng Huo once more.

Family, Friends and Enemies

Family: None recorded (fictional character).

Allies: Meng Huo (whom he agrees to avenge); Dai Lai (the intermediary who recruits him).

Principal adversaries: Zhuge Liang (who devises the fire-beast counter-measure), Zhao Yun and Wei Yan (the first Shu commanders to face him).

Historical Note

King Mulu is a pure novelistic invention. No contemporary or near-contemporary source mentions a Nanman sorcerer-king of Bana Cave, still less one who commanded storms and wild animals. The entire episode—his recruitment, his magical powers, the fire-beast counter-measure, and his death under the hooves of his own elephant—exists solely to provide a spectacular mid-point obstacle in Zhuge Liang’s southern campaign and to prepare the way for the still more extravagant confrontation with Wutugu and the rattan-armoured troops. In both the novel and later popular culture he remains the archetypal “beast-master” of the Nanman.
