Sei slid into the illusion of the wall, entering the tunnel that it hid from the outside world, sweating and breathing ever so slowly. After all, there was a well-versed chance that the figure might be hiding inside the dark tunnel to wait for him.
Sei slowly walked into the darkness, with slow deliberate steps on the rocky uneven floor. The tunnel was the same as always—calm and filled with a rusty smell—but Sei's mind was in chaos.
'Where did the man go?' he pondered while walking through the dark, slowly advancing towards the other side that opened inside the academy.
The tunnel ended. Sei reached the other end unharmed and didn't encounter anything unusual. He squinted his eyes in suspicion before abruptly turning back to look one last time. He slid his gaze through one last time—everything was normal.
