"Master Wu, what did you call me?" Wang Daniu stared at Master Wu's smiling face, somewhat in disbelief.
Master Wu was overjoyed, clapping Wang Daniu's shoulder, somewhat excitedly said, "Brother Daniu, you still try to deceive me? You might fool others but not me. Your appearance and voice may change, but palm prints and fingerprints are innate, how can they change?"
"You… you must have mistaken me for someone else?" Wang Daniu blinked his eyes.
Master Wu chuckled, knowing he'd have to present some solid proof before Wang Daniu would admit anything.
"I've had a photographic memory since I was young." Master Wu grabbed Wang Daniu's right hand and said with a light smile, "I've seen your fingerprints, remembered them very clearly, and fingerprints are unique. Faces can change, but fingerprints and palm prints don't. I recognized you as soon as I saw you take off your gloves."
