After a long time, he shook his head, returned his sword to its scabbard and turned, leaving the Tower of Purging Dust.
Within the tower, only Chen Chang Sheng remained. He looked at the empty arena, looked at the grey wall opposite and slightly tilted his head, seeming to be rather bewildered.
It was very quiet, without any sort of sound.
His gaze persisted for a long time before he finally regained his senses, feeling rather tired, wanting to rest for a while.
He retreated backwards a few steps, getting closer to the wall, slowly returned his short sword to its scabbard. He then sat down, wiping his forehead, but it was hard to determine what was on his sleeve, be it blood or sweat.
