阴山禁地

Jia Fan, a locksmith from a small town, ventures into an ancient tomb with his childhood friend Li Mu and others in search of the truth about his origins. Upon discovering that he is a descendant of the "Faqiu" lineage, he awakens his ancestral skills and gathers the complete "Sixty-Four Character Secret Arts" from the tomb of the Faqiu founder. He then battles a grave-robbing gang led by Wu Laoda—a "Mojin Captain"—thereby preventing the tomb from being looted and safeguarding the local community.
