Peng Hai walked up to a milky white wall nearby and drew an imaginary line. Soon, a vibrant hologram shone on the wall.
As Peng Hai quickly punched in a few glyphs, a burst of buzzing noise came from the ceiling before a metal disc lightly fell from above.
The disc was approximately two meters in diameter, and with over a thousand glyphs engraved on a winding course, it formed a spiral-like glyph array. Its edge was slightly raised and was also embedded with over a hundred shining, transparent crystals. Evidently, one could easily discover an unlimited amount of starlight clustered at the center of each crystal.
It didn't take long for Li Yao to recognize that it was an extremely high-rank transmission formation.
From the many crystals inlaid on its edge, it was quite evident that this transmission formation required an exorbitant amount of spiritual energy to start. Certainly, the transmission formation must teleport to a very remote place.
