Why Am I Helping Qingmei Solve the Case in This Weird World?

"Liu Xingxing, how do you know what happened back then!" He asked her piously. "Liu Xingxing, how can this case be solved?" The detective asked her happily. "Liu Xingxing, if you think he is the murderer, who else can save us?" Everyone asked her in a bittersweet tone. Jiang Weiwei, who was suffering in the endless world of ghosts and monsters, watched Qingmei on the TV as she gradually wandered off. While regretting dragging her into these things, she silently kept an eye on the dangerous people who appeared around her.
