Appearance in Fengshen Yanyi
In the famed ancient Chinese novel ''Fengshen Yanyi''. Muzha is the second son of Li Jing and Lady Yin. In appearance, Muzha is seen wearing a small top knot, a silk sash, linen shoes, and a cotton like garment. Thus, Muzha was seen as a celestial being - such as that of a superiorman - in appearance.
For many years, Muzha had left his father, Li Jing to study under Superiorman Universal Converter of White Egret Cave. Following the rebirth of Nezha, and the near death of Li Jing, Li Jing would luckily run into Muzha -- as to save his life. Muzha would react with great anger towards Nezha and would soon battle it out with his renowned long sword against the fire-tipped spear. Soon enough during their fierce duel, Li Jing would try to make another escape; this was the point in which Muzha would be defeated by Nezha's golden brick -- which thrusted him to the ground due to its great weight. Following this point, Muzha would later present himself before Li Resounding, one of four superiormen of Nine Dragon Island. Unfortunately, Muzha chose to immediately kill Li Resounding at the first sign of defiance towards his words. Muzha would remain as a celestial protector of the Western Foothills with Nezha and Jinzha following this point.
