Cat's eye is a very intriguing thing.
It connects the inside and outside of the door, serving as a bond between spaces.
Inside the room, it was pitch black.
Du Wei stood behind the door, staring expressionlessly at the cat's eye, and even though it was dark in front of him, he could clearly sense that something was definitely standing outside the door.
Just for a moment, an eye pressed against the cat's eye, looking into the room.
He could be sure that the owner of that eye had definitely seen him.
But with Spirit Vision activated, there was nothing unusual outside the door.
Was it human or ghost?
Aside from himself, there were no other guests in the entire hotel, but if it really were a person, it would only be Mrs. Mary Shaw.
Du Wei thought for a moment, then slowly pulled open his overcoat and carefully slid the dagger back inside, making sure not to make any noise during the process.
However, suddenly, there was a click from outside the door.
