The architecture of No. 7 Mansion somewhat resembles the building style of Olay Great Capital, with an exterior that practically lacks edges and corners, favoring smooth transitions instead.
The mansion is painted in an off-white color, with a flat roof, and circular stone columns scattered throughout its corners.
It is said that in the past, nobles from Olay Great Capital lived here. After the outbreak of war, the property was nationalized, and following multiple auctions, it ended up in the hands of real estate developers who, for some unknown reason, didn't develop it and instead rented it out to become a themed restaurant.
And it was exactly during the time this restaurant was in business that the strangeness occurred.
More than one person died inside, including a two-star exorcist who also fell here.
The key to seal the door was in the exorcist's hands, and Huang Chen had it sent over as quickly as possible.
