A cramped space
Liu Hui Ying pinned Liu Fei Fei with a stoic gaze and asked, " Nanny Cheng cannot even see anything clearly, do you think that she can even see whether or not you were in the room? She most probably saw someone lying on the bed on which you usually slept and then took it as if you were the one who was sleeping there."
She noticed Nanny Cheng's struggle when she was trying to look at her, she was a detective and she did not have to stay with someone for a long time to see if there were any problems in their normal behaviour and she indeed noticed that Nanny Cheng had difficulty narrowing her vision, it took her a long time to focus on someone and that too when she was staying still if she was moving then Liu Hui Ying was certain that Nanny Cheng only relied on her hearing senses to find out who was the person who was standing in front of her.
