The surveillance footage captured her up to the point where she stepped out of the hospital, where she possibly hailed a cab. That was not within the surveillance range of the hospital, so they had no way of finding out where she was headed.
"Have you checked with the others? She left on her own accord," Lei Qingyi turned to Lu Yi. "Maybe she went home. Have you asked Aunty?"
"I did. She didn't go home," said Lu Yi, pressing his fingers against his temples. His head was close to bursting from the headache. He dared not imagine what he would do if she got into an accident in her frail state.
Yan Huan had left on her own will, that much was certain. Lei Qingyi watched the clip again. It was blurry, but he could sense that Yan Huan was calm and objective in her actions. She descended the stairs, left the hospital, and hailed a cab. In fact, she made her way to the entrance of the hospital, as though she was trying to avoid the cameras.
