The loud noise from before was a phenomenon caused by the Celestial Sword Sect as they tried to breach the entrance to this Grand Array.
The commotion from their attempt was perceived by everyone in the Purple Void Secret Realm, who found it astonishing. As for the Celestial Sword Sect, who were facing the commotion head-on, their experience was naturally the most profound.
They had originally wanted to sneakily hoard all the benefits of this Super Array for themselves but, in the end, had no choice. They simply couldn't stop so many other powers.
Since they couldn't monopolize the prize, they had to open it to all.
However, they didn't give up their head start. Otherwise, they wouldn't have destroyed the Teleportation Array that led directly to the Solitary Void Trial Array.
At the entrance of the Solitary Void Trial Array, the major powers left a few people behind as backup before everyone else entered the Trial Array to face its challenges and seek the opportunities within.
