Once that question leaves Aldrian's mouth, there is only silence. The answer could not be more obvious. Moments later, Aldrian separates those who know about the devils from the innocent ones. He then checks each of the traitors' memories, and after that, he asks the other elders to bring the evidence of the traitors' connection with the devils from the patriarch's chamber.
Patriarch Tang had his own method of communication with the devils, and some of the documents reveal how he made it easier for the devils to infiltrate the family's territory. Aldrian also shows the elders his own proof, which clearly exposes the collusion between the patriarch and a few others with the devils.
The moment Aldrian presents all of this, the other elders finally accept—though with heavy hearts—that their patriarch and several others are indeed traitors and have no defense against their punishment.
