The elevator quickly reached the ninth floor.
This building had one elevator serving two apartments per floor, making the rooms easy to find. As long as you entered through the correct main door, you'd know right away which apartment it was after exiting the elevator.

However, as she was pressing the doorbell, suddenly there came a clatter of footsteps from the nearby emergency staircase. The sound was too familiar, and Xiao He thought in surprise: No way—turning her head, she indeed saw the kid from the ground floor who had a fractured bone.
