Afterwards, Ting Yu pointed out how Fei used the mirror of light and shadow to open the door of the temple. Then, they saw a flash of spiritual light in front of Fei, and eight spiritual crystals suddenly condensed out.
Under Fei's control, the tips of the eight spirit crystals faced each other, surrounding the two stone pillars, forming a large circle in the air. Immediately there was a flash of inspiration, and a ray of light shot out from the tip of each spirit crystal.
The light converges at the center of the great circle to form a circle of light, and with the continuous injection of light, the circle of light begins to expand rapidly. Not long after, a blue light curtain like water waves appeared in the middle.
