Zhang Chen memorized the appearances of the heads around him as he advanced, lest they enter through the main gate and end up going in circles.
In truth, the reason they had entered through the back gate and needed to take such a huge detour to lift the seal in the central area was because Ghost Tomb had become involved. Otherwise, Zhang Chen could have taken Yu Ming and Gu Chen straight through the main gate to the location where the dark creature from the Higher Plane was sealed.
"It isn't a circular passage. It looks like we've reached the exit of the tunnel ahead."
At the edge of their vision, the firelight no longer extended farther and instead vanished. The senses of the four spread forward as well. It seemed they had reached a relatively spacious area, but it was definitely not where the seal was located. No aura like the one that had made Zhang Chen feel danger last time came from within.
"Be careful. We came in through the back gate, after all. We can't rule out traps left behind by the Ghost King."
When it came to vitality, no one could compare to Gu Chen. Although Ghost Tomb had comprehended the Great Dao of Life and Death and was likewise difficult to kill, his physical recovery ability was absolutely inferior to Gu Chen's. Thus, Gu Chen walked at the front to test the situation.
The gloomy passage opened into a square hall. There was nothing inside, but there were two doors on either side. The door on the left stood completely open, while the one on the right was tightly shut by a stone door. At the very center was a slightly raised circular stone block.
"Brother Gu Chen, I'll have to trouble you."
