It cost so much to trap Shen XIII on a single floor, cut off the power supply and lock the elevator.

The elevator is too easy to lock, so long as the door of the elevator, a stool or something, can't close it, the elevator will not be used (the elevator has its own backup power supply, in the case of power outage in the hotel, it can still run for a while).

trapped in Xiaojun on the third floor, they fell into darkness again and dared not move any more. They gathered their weapons together, held a place and entered a defensive state.

and tell Shen XIXIXIII about it....
