Yue Qianmen was one of the top ten elders at the Center Sect, and was in the Lianxu State.
He had the highest Cultivation state among the participants of the meeting, as well as the highest generation; Monk Duhai was the only one who was his equal. As such, he asked the question with an authoritative tone.
State Duke Lu replied with no change in his expression, "Absolutely no one is allowed to enter the Fiend Prison. Even if you want to interrogate a prisoner, he is only allowed to be brought out by the puppets."
In fact, those prisoners brought to the Fiend Prison had usually been interrogated by the Pure Heaven Bureau and various sects as much as possible, so there was seldom a need for further interrogation.
