Nan Hua walked out of the ward and headed towards the bathroom. After she entered, she saw that it was empty. The seventh floor didn't really have many people who would use this one because there was bathroom in the ward.
But she purposely didn't use the one at the ward.
Nan Hua took out disposable gloves from her pocket and then a mask that she had carried inside. Her hair had long been tied up to a ponytail, so it would not hinder her when she was moving around quickly.
Entering one of the cubicle, Nan Hua looked up at the ceiling. She climbed up the toilet and then reached to the ceiling where she opened the ventilation's window before climbing up.
Her movements were fast and quick.
She entered the ventilation and slowly made her way up.
