Christina stood in a palace above the clouds. It was as if the gods had built it. The pillars supporting the sky were hundreds of meters high. In front of her was a flight of stairs that led to an unknown place. Each flight of stairs was several meters high.
She had followed Watson to the underground city's 100th floor. She touched the World Transformation Mirror in the middle of the palace and entered that place.
She knew some things about the trial's final floor from her father, so she did not panic. The last level would clone the challenger and choose the environment based on their personal conditions. The World Transformation Mirror would usually select a place the person would be most uncomfortable.
