After penetrating through that light film, Zhang Tie came to a huge space which was like the size of a football field. He was in the geometrical center of gravity of the magnificent crystal pyramid.
After hearing the sound, Zhang Tie looked back and found the gate that he entered through had disappeared and turned into a huge piece of crystal. The entire space was sealed from outside, leaving Zhang Tie alone inside.
'What happened?' Zhang Tie became surprised while numerous runes appeared in those crystals and started to run fantastically. The runes ran faster and faster. In a couple of seconds, Zhang Tie, although with his knight's consciousness, had found that he could not identify those runes. After a few more seconds, those runes turned into the light.
