Chapter 1586: Yellow Water of the Netherworld

The trio slowly advanced ahead.

As they were following the trail of the group of four before them, they did not meet much danger along the way.

Those four young men did not leave the slightest trail behind when they kidnapped Zhao Ya and the others, which went to show that they had intentionally destroyed all marks of themselves.

In this ancient domain, however, perhaps because danger was all around, they could not bother about it anymore, or maybe they felt that no one would be able to follow them there—regardless, they had lowered their guard. That being said, their trail was still very faint, to the point of nearly being indiscernible, but fortunately, it was still barely visible through the Eye of Insight.

Those four are indeed powerful… Zhang Xuan thought grimly.

If not for his Eye of Insight improving along with his cultivation, even he would have had trouble making out their nearly indiscernible trail!
