Zhang Fu had long heard about the horrors of Dark Prison.
And having just undergone a round of brutal torture, he had profoundly experienced the terror of the punishment here.
Having heard Kou Hong's words, and having witnessed several cultivators being tortured into madness and disfigurement, he was very clear that he could definitely not endure the tortures here. Therefore, he decisively agreed to Kou Hong.
"If it really becomes impossible, the worst comes to worst, I'll just go back on my word and sell this person," Zhang Fu thought to himself.
However, all these little schemes amounted to nothing after he followed Kou Hong in reciting a pledge.
"Merciful Immortal?" Initially, Zhang Fu did not care about this so-called True Immortal, but later, whenever thoughts of betrayal surfaced in his mind, a mysterious sense of imminent disaster would inevitably arise.
Only then did Zhang Fu finally confirm that he indeed boarded a thief's ship.
