Grey remained silent for several seconds. His thoughts kept returning to what the old man had said. Although it sounded safe on the surface, there must be some hidden motive behind his words.
But even if there were, Grey couldn't do anything about it. He was completely at the other party's mercy.
"What would you like to know about the outside world?" Grey asked after a long moment. He stopped retreating, but the vigilance in his eyes did not decrease one bit.
When the old man heard his words, he smiled calmly before making a small gesture with his fingers. Very soon, a multitude of black threads appeared from the darkness and swarmed forward.
Each of these threads emitted an extremely powerful and life-threatening aura. Grey even felt that a single thread would be enough to kill him without resistance.
