Chapter 137: Exploring the Cave (2)
The steps of the stairwell led deeper down. Just like in the path that led them into the cave, it was pitch black without the slightest hint of light.
This was a bit confusing because inside the cave, they didn’t even need to use their flashlights because the place was as bright as day.
What was more astonishing was the lack of a visible light source in the cave. Chu Miao had examined around and couldn’t find the source of the light in the cave.
Not even the famous night luminous pearls. Eventually, she had decided to forget about it because it was wasting too much time.
Now, entering into darkness again, the siblings had to rely on their flashlights to see in front of them. The darkness here was different from that in the path leading to the cave.
It was darker. So dark that one couldn’t see their own fingers. She wondered what was at the end of the stairs.
The two kept walking forward and it was obvious that the stairs lead deeper underground. They were moving diagonally downwards.
The walls around them still had the same dark material used in the path leading to the cave. Chu Miao started suspecting that it was this material that isolated sounds from outside.
However, the question was, why do something that seemed almost irrelevant? If the cave was used for studying, isolating sound from the outside might make sense, but what about the path and the stairwell?
