Ghost Mirror.
Yang Jian didn't even know if this thing could be defined as a ghost, but it was, like the human skin parchment, seemingly harmless on the surface yet concealing a massive terror in the dark.
The mirror reflected his body but did not show Yang Jian's shadow.
The surface of the mirror was blank.
However, all this had been taken into account; the Ghost Mirror needed a bit of time to capture a person's shadow.
During this time, Yang Jian had to complete the remaining tasks.
He first controlled the Ghost Shadow to enter his body, while simultaneously unraveling the gold foil wrapped around the Ghost Rope.
Both tasks were completed at the same time to ensure he wasn't controlled by the Ghost Shadow after which, unable to untie the Ghost Rope, he'd die a haphazard and confused death.
