Ron said softly, placing the bottle back on the table, his voice calm yet courteous:
"The genuine Moon Shadow Bat Heart Ash should not be this color. It should be closer to silver and exhibit a faint blue glow under light, especially when the bottle is gently shaken. Most importantly, the real thing has a special magic fluctuation that can be felt even through the bottle."
A hint of surprise flashed in Otto's eyes, which was quickly replaced by admiration, his lips curling into a subtle arc under his beard:
"Nice eye! This is indeed a counterfeit, I just wanted to test your professional level."
He retrieved the bottle, a hint of appreciation in his tone: "In this line of work, distinguishing between real and fake is a basic survival skill."
Then, he took out a more exquisite-looking small bottle from the depths of the box.
