Cao Ruomei's disappearance.

Cao Ruomei searched her pockets to bring out his spare medicine that she always carried with her and put some into his mouth, trying her best to make him swallow it but he was too weak so she was forced to put some into her mouth and chew. She endured the bitter taste and bent down to kiss him, transferring the liquid medicine into his mouth and she continued to push some into his mouth until he finally swallowed it. She wiped her mouth clean and also used her thumb to clean his lips as she said. "Take a rest now. I will wake up later."

She glanced at her wristwatch where the time showed that it had reached midnight so she was not worried that she would be discovered since she had already tied up the unconscious police officer and she knew that his shift would last throughout the night. She stroked his head as he slept and waited.
