After all, if that were the case, there would inevitably be a conflict between the two, and Feng Xiaoyan would definitely scream and even knock on the neighbors' doors, surely disturbing the other residents in the building.
However, according to Chief Zhou's investigation feedback, no strange sounds were heard by nearby residents last night.
So this point can basically be ruled out.
Next is the second hypothesis: Guo Tiejun was telling the truth, the door was not opened by him but by Feng Xiaoyan herself.
But Feng Xiaoyan didn't do it intentionally; she was deceived by the Fierce Ghost disguised outside the door.
However, Yang Xiao doesn't quite agree with this either. As mentioned, Feng Xiaoyan's vigilance last night should have been high; it seems unlikely she would open the door recklessly.
Moreover, the only people who could be called insiders in this building were her and Guo Tiejun; the other teammates didn't live in this building.
