Identity and Motives: The protagonist is renamed Chen Ji, a data analyst who is on temporary leave due to a laboratory accident. He rented Room 303, Building 11, with the initial motive of seeking purity. His strong logical thinking ability and keen intuition of anomalies drove him to transform from "passive compliance" to "active experimentation" - he systematically recorded the mutation rules of "Sundial Chronicles" and designed small-scale, controllable rule trials to build a "behavior model" of the building. In the middle, he discovered that his missing mentor had been an early researcher in this building, and his goal changed to deciphering the building's operating logic and finding the core data left by his mentor.
· Special abilities: Chen Ji does not have supernatural abilities, but because of his instinct as a data analyst, he can interpret the "information flow" contained in the plaque texture of "Sundial Chronicles". He was able to determine the "weight priority" and "danger incubation period" of the rules through the growth direction and density of the plaque, thereby discovering the key information that "the seventh floor is the 'buffer overflow area' of the building's logical flow."
