For a while, the middle-aged man snapped back to his senses, turning off the small tool in his hand.
He touched his stubble, his expression strange, as if he had encountered some unparalleled problem or as if he had seen some brilliant solution.
There was a contradiction and confusion mixed with a hint of unexpected joy, or perhaps, unexpected shock?
"Huh..."
A huff escaped his lips, but his face showed no signs of jest.
He gave an indiscernible look at the brand new copper coin on the table and, after a moment, bent down again.
This time he flipped the copper coin over and took out the inspection tool, carefully choosing the angle. With his eyes intently fixed, he aligned it precisely before switching it on.
Hum—
The clear, metallic buzzing sounded once more.
Seconds later, the middle-aged man turned off the tool.
The humming stopped instantly.
The man took a deep breath, squatting there.
He appeared quite calm on the face.
