That was a middle-aged man who took the Evil Eye from Duan Gujin and examined it carefully for a moment.
After confirming that the Evil Eye was indeed the eyeball of some kind of demon, the middle-aged man then placed the Evil Eye into the eye socket of the Ghost Mask.
He compared it and judged that the Evil Eye was a perfect match for the Ghost Mask.
"Now, my friend, may I ask if you know what kind of demon this monster really is?"
The middle-aged man became interested immediately.
Duan Gujin said, "Please prepare a piece of paper, ink, and a brush, and I will draw it for you right away!"
"Okay!"
The middle-aged man waved his right hand and called over an attendant.
After taking the instructions from the middle-aged man, the attendant hurried off to prepare paper, ink, and a brush.
Moments later, the attendant rushed back and placed the paper, ink, and brush on a table, then asked Duan Gujin to come over and draw.
Without hesitation, Duan Gujin stepped forward to draw.
