The reason Su Yu has not taken action yet is because [The King]'s will is still strong; although struggling and screaming in the hell prototype, [The King] has not yet collapsed and begged for mercy.
For now, it's unlikely to extract any information from it.
However, Su Yu is not in a hurry. Once [The King]'s will is worn down by Hell's Pain, it will answer whatever Su Yu asks, just to relieve a moment of suffering.
Hell torture is the best interrogation method, capable of turning the most resolute warriors into obedient prisoners ready to answer any question.
Unless there's a genius who can, in the midst of Hell's Pain, comprehend the true essence of the Power of Hellish Suffering, use this pain for cultivation, and break free to strike back.
But Su Yu is already a peerless genius on the Path of Hellish Suffering, with talent far surpassing that of [The King]. Therefore, once ensnared in Su Yu's hell prototype, there's basically no chance of getting out on their own.
