The bed slats were rather thin. Gu Mian lifted the mattress and quickly sawed through them.
It was worth mentioning that Zhao Guanhai seemed to have taped his bank card and diary to the underside of the bed slats.
But for some reason, these two items, which should have stayed stuck to the underside of the bed, had fallen to the ground. Part of the card was poking out.
Some tape was still wrapped around them.
Untangling tape in the pitch dark wasn't exactly easy.
Even in broad daylight, Gu Mian would struggle to unwrap packages, let alone at this late hour.
After pulling off the tape, Gu Mian glanced at the bank card. There was nothing unusual about it. He quickly turned his attention to the diary lying next to it.
This notebook was rather thin, seemingly having only about thirty pages.
Zhao Guanhai would squeeze many days' worth of diary entries onto a single sheet of paper, evidently to conserve the notebook.
