Wang Yan didn't notice Su Yamo's blush because he was concentrating on analyzing the murder case.
At this moment, the silk panties were in both of their hands, and Wang Yan said, "Some threads on these silk panties were torn, which must have been caused by the murderer's ring on their right hand catching on it when they pulled it out of their pocket. I've carefully observed that the position where these threads are torn forms a hexagon. So the gemstone shape of this ring is hexagonal."
Sure enough, Su Yamo saw that several threads at the corner of the panties were torn, and the shape of the tear was exactly hexagonal.
Upon hearing this, Su Yamo was utterly shocked and urgently wanted to know all the answers. She had completely forgotten her earlier embarrassment and asked repeatedly, "But how do you know her breasts are twice the size of mine?"
Upon hearing this question, Wang Yan glanced at Su Yamo's chest and mumbled, "I'm not sure about that, I need your help."
