The brown-robed old man led the way.
He reached the end of the corridor and pushed open an iron door. He extended his hand and gestured the way inside. He motioned for Wang Wen to enter with a strange smile on his face.
Wang Wen straightened his lapels and smiled politely at him, like a noble and elegant gentleman. Then he walked through the door.
The iron door behind him was closed after a few steps.
The old man did not follow him in.
Wang Wen stood still and looked around.
It was a sealed room.
The surrounding area was illuminated after the metal door at the entrance was closed.
The wall had turned transparent.
The brown-robed old man was standing outside the wall, looking at him with a mocking expression.
