This was a valley on the western side of the Fourth Sea Island. From the sky, this valley looked very similar to the countless other valleys on the island: a vast and utterly barren basin without a trace of vegetation.
However, guided by the legacy black pearl, as Ye Chen flew above the valley and looked closely, he could sense faint fluctuations of the Heaven and Earth True Qi emanating from below.
Clearly, this valley was not barren at all. It was not as simple as it seemed and held secrets within!
After flying back and forth over the valley a few times, Ye Chen stopped at a certain spot in the sky above it.
Then, he formed a spell with his hands. Suddenly, the legacy black pearl, transformed from the wooden plaque, burst out from his body and flew towards the valley below with a thunderous speed.
When the black pearl reached just two or three zhang above the valley floor, it seemed to touch something and exploded with a bang.
