Han Sen was behind Ancient Devil. He kept walking silently. When the next stone clock rang, the danger was considerably less. The speed of time in different areas could be segmented. As long as one did not have a death wish, one would be fine.
Han Sen wanted to ask Ancient Devil if he fought against Bury Path God and big sky demon over the relics. If he asked that, Ancient Devil would know he had been there. Therefore, Han Sen did not ask him anything about that.
Ancient Devil kept walking. He eventually said, "It is pointless to keep on following me. I do not know where the sky clock is. I am only trying my luck like you."
"You are luckier than me, so following you gives me a better chance." Han Sen did not do anything. He carried on following Ancient Devil.
Ancient Devil kept walking and said, "The sky clock is hidden amongst the stone clocks, but no one knows which one is the sky clock."
