Zhao Xinli's protest was futile as he was dragged by Zhou Ning to the door of the seventh-floor eastern unit. The floor was rich with footprints; after all, only a few households had moved into this complex, and the hallways were coated with thick cement dust. Such trampling had left the ground covered with overlapping footprints.
Zhou Ning looked at the ground, feeling overwhelmed with a sense of helplessness.
There was no escape; Liu Changhai was seized by Zhou Ning for labor, along with Mr. Zhao. One took photos while the other positioned the investigation mats to protect the traces on the scene as much as possible.
Before long, Mr. Zhao and Liu Changhai stepped out of the room on the investigation mats and handed the camera over to Xu Dayuan and Zhou Ning.
