Before leaving the cabin, he was drawn to the patch of dried brown bloodstains on the wall. He stared at it intently for several seconds. The more he looked, the more irritable he became, the less he understood why they had come here.
What secret was hidden here?
Li Yeqi stepped out of the abandoned warehouse, the just-risen sun showered him with light, easing his breath a little. He stepped into his car, started the engine, and reversed out.
Han Zheng returned to the police station. He took out a cartridge casing from his jeans pocket. It was embedded in a very hidden corner of the wall, probably overlooked by both the police and the person trying to destroy the evidence. That's why it had survived until now.
He toyed with the casing, lost in thought. This was no ordinary cartridge; it bore the imprint of a bellflower, a mark he had never seen before. After a while, he took a photo of the casing with his phone and sent it out.
