Chapter 623: Paying the Bill

Qin Xue was curious, she didn't know that Gu Beilin and the others had already left.

"I heard the sound of two women walking past," Chu Molin pointed to his ear as he spoke.

"You could hear that?" Qin Xue widened her eyes and asked him.

"Yes, the sound of a man walking is different from a woman's," said Chu Molin, who was trained to discern such details.

"I know their footfall is different, but I always feel as if the difference isn't huge. If you don't pay close attention you can't tell," said Qin Xue, a medical student, who knew about this but had trouble discerning the difference.

"A man's body scent is also different from a woman's, you can judge based on these two factors together," Chu Molin softly told his wife, who alternated between shrewdness and silliness.

"Oh." Qin Xue could tell the difference when they were close, but from afar she couldn't discern as accurately as Chu Molin just did.
