911 Highest Difficulty Mission

The chance of running into special visitors will multiply at night? The black phone is encouraging me to open for business at night?

In the morning, Specters could only hide in the Haunted House. Even ghosts like Ol' Zhou and Duan Yue were afraid of the sun. They could only appear for a few minutes in the morning and could not be hit directly by the sunlight. If it was night, there would not be such limit, and thus, the Haunted House would be several times scarier than daytime. Not only because the environment had changed but also because most of the employees were actual ghosts, and the closer it was to midnight, the more active they were.

The problem with the door hasn't been resolved, so the visitors might be accidentally injured if a Specter sneaks through the door.
