The Purple Void Secret Realm.
"Your Majesty found some ancient texts related to the Purple Void Secret Realm. This place was the Purple Void Imperial Dynasty's spirit medicine plantation, cultivated by the Void Spirit Race. There were a few other alien races as well, though the texts didn't specify which."
"However, the texts also mentioned that to keep these alien races in check, restrictions were put in place within the Purple Void Secret Realm. These restrictions made it difficult for them to break through to the Blood Exchange Martial Saint Realm, and practically impossible to advance beyond it."
"The guiding principle of the Purple Void Imperial Dynasty back then was: 'Those who are not of our people will surely have different allegiances!'"
"They used the harshest of methods when dealing with these alien races!"
"It's just a mystery why the Purple Void Imperial Dynasty suddenly vanished from the Taiyu Divine Continent, leaving not a single trace behind!"
