Xie Wensheng looked at the half-drawn face Chen Xiao had sketched, full of confusion.
"Whose smiling face are you drawing?"
"It's no one's."
"Then why are you drawing it?"
Xie Wensheng inquired.
Chen Xiao took a deep breath and replied, "The hardest part of our discussion is that the murderer wanted to kill these six people, yet they were completely off guard during their last meal. This indicates that they had met the murderer before and were very familiar with them."
"Moreover, the murderer is very familiar with the local area, otherwise, it would have been difficult for them to connect Xiong Ruru's tattoo 'Renxin Bridge' on the tiger's mouth spot and equally challenging to recall Yaoxi, an old place name that was replaced over a decade ago."
Xie Wensheng nodded, tentatively saying, "So, the half face you've drawn is a smiling face, while the other half is one showing menace, right?"
