As the person who called herself Sister Hong walked into Room 504,
the lobby on the fifth floor of the post office returned to calm once more.
Yang Jian got some information from this Sister Hong and roughly understood the next steps he needed to take.
Destroying the post office completely is unrealistic; the only remaining option is to control the post office, and then, after gaining control of the post office, change its rules to completely cancel the letter delivery task. He hasn't decided on what the Ghost Post Office will become, but he definitely disagrees with Sister Hong's idea of turning it into a center for handling supernatural events.
Because such an approach is essentially no different from delivering letters; instead, it is more cruel, and forcing incapable people to deal with supernatural events is not only sending them to their deaths, but also causing chaos.
