Undoubtedly, there was a ghost standing behind the old wooden door mounted on the dilapidated wall, separated from the living inside the room by merely a wall.
Moreover, the most unsettling part was that the ghost was actually knocking on the door.
"Thump, thump-thump!"
The dull, oppressive sound of the knocks seemed to drift in with the darkness outside, and this knocking was all too familiar to Yang Jian.
Without question, these were the knocking sounds of the Door Knocking Ghost.
But...
After the sound of knocking, no one in the room died, not even Wang Shan, who was just a regular person. This was clearly abnormal because ordinarily, someone should die after the knockings, and while a ghost manipulator might withstand one knock, an ordinary person would have no reason to survive this almost certain death rule.
So, this wasn't knock-to-kill.
If the knocking wasn't to kill, what was it for?
Yang Jian's expression changed as he stared intently at the timeworn wooden door.
