Lu Feng understood this strange movement of the Kirin Ring very well. Hao Ran was indeed connected to the Ancient Desolation Altar!
It was still the disturbance caused by the Mysterious Ball on the newly opened third level. Before this, whenever it neared the Vitality Sword, the Mysterious Ball would faintly stir. Especially when the Vitality Sword had been seized by Ji Lanxin, that stirring had been particularly obvious. Had Lu Feng not deliberately suppressed it, it would likely have flown out more than once already.
With no one beside him now, Lu Feng no longer suppressed the Ancient Desolation Altar's aura and allowed it to fly out of the Kirin Ring.
Sure enough, the instant the Ancient Desolation Altar appeared, the Mysterious Ball in its third-level space pounced toward the iron rack and wrapped the black lump within the ancient iron box into its body.
Although Lu Feng could not make sense of this strange phenomenon, he had no time to worry over it. Letting the Mysterious Ball fuss about as it pleased, he began searching for the mechanism that would open the hidden passage.
He practically turned over every rack and every object in the Stone Chamber, yet failed to find any mechanism capable of reopening the hidden passage.
Lu Feng's expression gradually grew anxious. Chu Youwei had fallen into that hidden passage some time ago, yet even now, he could not determine whether she had fallen into the Sword Scabbard Space beyond the Stone Chamber, or somewhere else—
If it was the former, then from such a height, Chu Youwei was likely doomed;
If she had fallen into something like the lava from earlier, or the like...
Lu Feng knew full well how perilous Chu Youwei's situation was. There was no room to delay any longer!
