Driven by curiosity, Chen Nan continued to swim forward.
About two hundred meters ahead, more brilliant white lights appeared in front, not just one this time.
Without a doubt, these were the skeletons of peerless masters.
Chen Nan's heart shook. So many peerless masters had all perished here! He swam closer and, without any surprises, these were all female skeletons.
Piles of white bones stacked like mountains.
The size of the Underground Lake was unknown, and Chen Nan followed the direction where the bones were most densely piled, constantly swimming forward.
He swam at least two thousand meters, and along the way, there were bones everywhere, with the most being those severely decayed emitting a faint glow, estimated to be in the thousands, and those with slightly brighter light, also in the hundreds.
And the skeletons of the peerless masters that shone like lamplight numbered over twenty.
