Jia managed to recover the phone and called for help, while the signal was fitful, and she cannot even remember her bes-tie or relative's number. The destroyed elevator fell again, iron stabbed into her thigh and caused badly bleeding. Jia kept trying on dialing, without the expectation to find a hidden conspiracy, as well as a bloody monster lurked deep in the dark.
