A Dilemma

"Fellow Daoist Lü, the void of Hidden Dragon Cave should revolve and transform according to the number of three hundred and sixty celestial cycles. By my calculations, there are twelve major cycles, switching once every twelve hours, with endless variations..."

Shui Yunzhu, dressed in elegant blue, said softly, "If we cannot comprehend the rules governing the central transformations, we could remain here for ten thousand years and still never unravel the secrets of this grotto-heaven, much less enter its core."

Lü Tiannan, clad in red with a sword at his waist, nodded slightly. Though he was not skilled in mathematical arts, he could still see that the Hidden Dragon Cave grotto-heaven had far too many variables. They had been here for a year already, yet had failed to make any sense of it.

No wonder none of the sixth-rank Pure Yang powerhouses came here. Without finding the rules behind the formation core's transformations, one could only keep cycling through thousands upon thousands of fragmentary spaces. It was utterly meaningless.

A year was negligible to a Spirit Transformation powerhouse. Yet after an entire year with no progress whatsoever, he was beginning to lose patience.

Lü Tiannan asked, "Since we cannot break the void formation, are we still going to continue?"

"In my view, although we cannot break the void formation, we can still enter certain special grotto-heavens amid the shifting void and obtain some opportunities."

Shui Yunzhu said, "These void transformations do not change the entire grotto-heaven at once. Rather, they are interwoven like a bamboo basket. Different grotto-heavens can join and combine, forming a new grotto-heaven.

"Just as the fragmentary void we occupy can shift through different directions into different fragmentary voids."

"I understand. You two mean for us to explore separately." Lü Tiannan understood. These two beautiful mermaids wanted
