The layout of the ward on the fourth floor was different from the second and third floors. On one side, there was a special treatment room, while the wards were on the other side. Since all the patients in the ward were highly aggressive, there would also be security guards apart from all the nurses and doctors.
Something had happened in the surveillance room. The door closed with a loud rattle when she went upstairs. However, both ends of the corridor remained quiet. No one came out to check, and even the nurses' station was silent. It was an unusual situation.
