Holding up their flashlights, the group entered the Nether Acupoint.
First came a set of stairs sloping downward, the staircase was so long that one couldn't see its end at a glance.
Ye Yuqiao carefully observed her surroundings without spotting anything out of the ordinary. It wasn't until they were halfway down that she noticed something slightly different about the walls on either side.
The wall on her left exuded Yang Energy, constructed of meticulously carved Yang Stones; the right wall, however, was built of Yin Stones.
The so-called Yang Stones were those which had been bathed in sunlight for years, soaking up the Yang Energy between heaven and earth; Yin Qi, on the other hand, was the exact opposite, found in stones that had not only been deprived of sunlight for long periods but also located near graveyards, battlefields, or pits of thousands of corpses.
