The seven Celestial Nether Towers were all located within the massive and magnificent halls of the Cyan Nether Sword Sect.
Powerhouses on the outside had no way of directly seeing the changes within the Celestial Nether Towers, but this wasn't much of a problem.
After hundreds of years of development, the Cyan Nether Sword Sect had long since devised its own unique methods to display the combat situations of the powerhouses inside the Celestial Nether Towers.
Of course, even after the screening in the Cyan Cloud Secret Realm, there were still a thousand powerhouses remaining. It was naturally impossible to display the battle scenes of so many people at the same time.
For this very reason, there was a special team within the Cyan Nether Sword Sect.
This team, led by an Inner Sect Elder, operated over a thousand miniature Mirror Image Arrays.
As the name suggested, a Mirror Image Array was a type of Array that could display scenes.
