When a Super Array appeared, the great powers naturally didn't want to miss out. They joined forces to break it, but ultimately failed to dismantle it completely. They only managed to open a passage for entry and exit, but this became the source of the calamity—the very reason the Alien Race appeared on the Taiyu Divine Continent.
Otherwise, even with multiple masters at the Blood Exchange Level, the Alien Race would have remained suppressed by that Super Array, unable to leave the Purple Void Secret Realm.
The Purple Void Imperial Dynasty had originally prepared this Super Array for the Alien Race. It was capable of suppressing any existence below the Divine Acupoint Realm, so it could naturally keep the aliens in check. It could even leverage the Grand Array's might to reduce their combat power by a significant margin.
