The End of the World: Weird Game

Zhu An is an orphan. She is withdrawn and stubborn and never talks to others. Even if she is isolated and treated coldly by others, she never cares. I have been alone for ten years and five, and nothing in the world has entered my heart. There was only one thing that bothered her for fifteen years, making her unable to sleep at night. In that fire that destroyed everything many years ago, where was the real culprit hiding? Something strange happened, and she was forced to step into the S-level dungeon and face her former family members who had turned into a terrifying BOSS. She is obsessed with finding out the real murderer and getting the long-overdue justice. But the "family" who was lingering in her dreams told her: "Let go of the past and leave the future to yourself." With a desperate future on one side and family members she hasn't seen for a long time on the other, what should she do?
