Xue Xiaofei was really stunned when she entered the mansion. It is because the corridor alone seemed to be endless. She couldn't see the end of the corridor. Furthermore, the walls of the mansion inside were simply too tall and strong. She was sure that she could fight against a martial artist with the same strength as her in this corridor with full strength but it'll not cause any damage to the walls. The material of walls seemed to be very strong and durable.
After walking for a few minutes, they finally exited the long corridor, and the space in front of them widened suddenly. Xue Xiaofei was shocked to see the true face of the Sky Dragon Sect that appeared in front of her just now.
It seemed that the mansion outside was just an illusion created by laying down a powerful formation. The true Sky Dragon Sect was hidden behind the curtains, completely invisible to the eyes of outsiders.
