Following the sound, Zhou Ning quickly ascended the stairs, with Xu Dayuan right behind him.
Mr. Zhao held up an evidence bag containing an L-shaped object, dark and seemingly metallic, with one broken end showing signs of chopping.
Zhou Ning recognized it as a doorknob. Despite its simple design, the craftsmanship must be expensive since it didn't peel or deform even in the fire.
However, it seemed to bear a crocodile-skin-like pattern. Taking the bag from Mr. Zhao, Zhou Ning lifted it for a closer look and instantly thought of the scars on Dong Chengwen's hands.
"The main bedroom's door handle? Mark it for the record, and test the skin tissue on it when we get back. If Dong Chengwen wasn't lying, then this should be from the skin of his hand."
Xu Dayuan took a glance with a look of disdain and then stared at Mr. Zhao.
"Just for this thing, you're making a big fuss?"
Mr. Zhao's face was like that of a bitter gourd as he spread his hands towards Xu Dayuan, pointing around.
