Background

Liu Xing is a 22-year-old graduate of Rongcheng University of Traditional Chinese Medicine. Born into a family that has practiced medicine for three generations and owns three clinics, he refused his father’s offer to join the family business because he wanted broader experience. After clashing with a department director, he resigned and was left unemployed while searching unsuccessfully for hospital work. 1

A longtime Cthulhu Mythos tabletop RPG enthusiast, Liu Xing clicks an advertisement for the Cthulhu Mythos Tabletop RPG Game Hall while passing time at home. He registers under the ID Old Chinese Doctor, a name reflecting his lifelong study of traditional Chinese medicine under his grandfathers. 2

His first Novice Room session establishes his approach to the Game Hall: rather than merely survive, he investigates the mansion’s family-annihilation case, identifies his three companions as ghosts, and completes the side quest for an A-level evaluation. 4 5 6

Cthulhu Mythos Knowledge	1
Credit	50, temporarily 60 after the Ains Castle hidden ending
Damage Bonus	None

His high Intelligence, Inspiration, Education, Willpower, and Luck make him effective at gathering information and resisting mental pressure, but his low Constitution, small build, 8 HP, and lack of damage bonus leave him highly vulnerable in direct combat. His high Inspiration is especially dangerous, as it increases his likelihood of encountering abnormal phenomena and suffering forced SAN loss. 6 9 39

Personality

Liu Xing is analytical, cautious, and proactive. He habitually examines inconsistencies in behavior, scenery, and game logic, then turns them into working theories. This allows him to expose the Novice Room ghosts, recognize the Elder Sign wallpaper ruse at Ains Castle, and identify the electric gate opener as the group’s viable escape route. 5 26 27

He is also willing to accept calculated risks when greater rewards are at stake. He insists on pursuing the Novice Room side quest, climbs to Ains Castle’s second floor despite poor Climb skill, and takes the ominous parchment because it may weaken the scenario’s Magician boss. 4 19 20

Despite his self-preserving instincts, Liu Xing prioritizes team survival when practical. He builds his Character Card around healing and SAN recovery, volunteers to negotiate with Gary, and argues that rescuing Minami Kotori would improve the group’s eventual evaluation. 9 28 50

He is susceptible to exceptional beauty. Isabella’s appearance causes him to lower his guard, making him vulnerable to her manipulation during the Ains Castle scenario. 21 37 38

Story Role / Major Arcs

Novice Room

Liu Xing enters the Ghoul Area’s Novice Room under the identity Old Chinese Doctor. He refuses to settle for merely protecting the candle, investigates the side quest, exposes the three apparent players as the ghosts connected to the mansion’s 2000 family-annihilation case, and earns an A-level evaluation. 3 4 5 6

Ains Castle

As the team’s doctor and investigator, Liu Xing probes Old Wayne, infiltrates the castle’s second floor, takes Gary’s parchment, and establishes the electric main gate as the group’s escape route. He serves as the group’s negotiator at the banquet and against Gary. 15 19 20 27 28 30 32

Liu Xing helps Isabella escape Gary’s control and reaches the hidden ending, though he later learns that Isabella had manipulated him into recovering her necklace, controlling the ghouls, and shifting blame for the killings onto Gary. His 42% contribution rate earns him MVP status, 120 points, and contacts with Isabella and Chris. 36 37 38

Intermission Growth and Harvest Festival

Following Ains Castle, Liu Xing reflects on his mistakes and uses Intermission Growth to improve First Aid, learn English, and gain driving ability. He then begins his first Shoggoth Area Advancement Match, Harvest Festival, where he joins a new group of players and investigates the ritual’s offerings and the Mirror World threat. 39 40 41 42 45 50

Trivia

• Liu Xing’s game ID, Old Chinese Doctor, comes from his inability to choose new usernames and his childhood training in traditional Chinese medicine. 2
• He habitually “pushes up” nonexistent glasses when presenting a deduction. 4 5
• He is a Manchester United fan; the Game Hall assigns him a Manchester United jersey in the Ains Town scenario, leading him to suspect that it can read his mind. 10 11
• His grandfather taught him to reflect on important experiences and summarize both successes and mistakes. 40
