A thin curtain like a steam with space ripples covered Shi Yan's group. The teenager was still cautious, maintaining a distance from Shi Yan with eyes filled with anger.
Then, he turned and looked at the ice crystal opposite to them. He became totally baffled.
That ice crystal was smooth and flat like a mirror, which reflected everything clearly.
However, he couldn't see his image reflected in it even though he was facing that mirror ice crystal.
Any creature with a body would be reflected in the mirror. It was the rule of Nature that people couldn't break.
However, they were standing in front of the ice crystal and that crystal didn't reflect their images. And he could still see that crystal. This observation made the youngster realize something. He quieted down.
