What Do You Mean, I'm an Urban Legend?

Urban Legend File No. CN-1977. Sequence: 0 — an unsolvable calamity, tentatively designated “Martial God.” The target usually appears as an ordinary human calling himself Xia Qing, but in combat may manifest as an ancient warrior wielding a fangtian halberd, along with other erased high-output forms. He insists that every abnormal and supernatural ability he possesses was gained through relentless martial arts training—despite there being no known martial art capable of producing such effects.
