Upon learning that Death was searching for him, a scientist used cloning technology to create a "double," hoping to preserve his life by deceiving Death.
Faced with thirteen identical individuals, Death was temporarily unable to distinguish the real target and could only leave in frustration.
However, not long after, Death—who possessed a profound understanding of human weaknesses—devised a clever way to distinguish truth from falsehood.
Death returned to the thirteen identical scientists and said, "Sir, you are indeed a genius for being able to clone such near-perfect replicas.
But unfortunately, I have still discovered a tiny flaw in your work."
Before he could even finish, the real scientist erupted in anger and shouted defensively, "That's impossible! My technology is perfect! Where could the flaw be?"
"Right here," Death replied, seizing the man who spoke and leading him away.
A single word of criticism or flattery can often cause a person to inadvertently reveal their greatest weakness.
