Xiao Meng works as a nanny for the Sima clan's children, though his role extends far beyond childcare. A eunuch, he's a member of the Crippled Legion—a position his status technically qualifies him for, though he's deeply sensitive about the subject and reacts badly to anyone who brings it up. His beauty is legendary, almost unnervingly so, which only adds to his prickly nature around anything touching on his gender.
Within the Legion, Xiao Meng handles logistics and serves as a field operative, whether defending flanks during combat or working undercover. His exceptional archery skills and striking appearance have consistently proven invaluable to his comrades. During a covert mission targeting Dong Zhuo, he took on the alias "Diao Chan"—a name forever linked to one of Chinese history's most famous (and entirely fictional) women, a connection that follows him even now.
Like Liaoyuan Huo, Xiao Meng is fiercely protective of his comrades and forms deep attachments to them. Despite his status as a eunuch, he's developed genuine romantic feelings for Liaoyuan Huo, and it's fairly clear those feelings aren't entirely one-sided.
