Yu Zhiyan is a contemporary Chinese online-fiction author about whom limited public information is available; details of birth and death dates, place of origin, and educational background have not been clearly recorded. Two of the author's works are currently held in the collection, namely Death Overlay and The Walking Secret Rune, with the common categories centering on war and military themes and otherworldly continents. Judging from this range of subjects, Yu Zhiyan does not confine the writing to a single genre: on the one hand the author engages in military and war narratives, and on the other constructs fantastical worlds of otherworldly continents, showing a tendency to move between realistic texture and imaginary settings. Owing to the lack of the author's own statements and of critical commentary, the specific writing style is difficult to discuss in detail, yet the two representative works already sketch the breadth of the author's chosen themes. Readers interested in military subjects or otherworldly adventure stories may take these works as a starting point for becoming acquainted with this author.
