Returning the way I came was now impossible; Yang Xiao only had two choices left: either take the recently used elevator, where someone had just died, or climb down the stairs.
A few seconds later, Yang Xiao quickly returned to the elevator, darted inside as soon as the doors opened, pressed the button for the highest floor, the 19th, then swiftly darted out again, standing outside the shuddering, old elevator doors, waiting for them to close. Once the elevator began to ascend, he turned toward the stairs and quietly started to descend.
The "squeak squeak" of the elevator moving away gradually gave Yang Xiao a sense of security, as if some danger was receding from him.
