After Mo Tiange entered the door at the innermost part of the hall on her White Silk Handkerchief, she looked around. This was another narrow stone alley just like the one they passed through when they came here. However, the walls here had moonstones inlaid in them, so she didn't need to light fires like she did when she first came to this place.
In fact, this was relatively strange. Moonstones rarely lasted several thousand years. According to reason, an Immortal's Cave from several thousand years ago ought to be pitch-black, just like the path they passed at the beginning; how could the Moonstones still be functional?
Daoist Fangzheng also had the same thought as her. The two of them stood facing a wall; each pried out a Moonstone.
"This..." After studying it, Daoist Fangzheng said, "Seems to be the Mother of Moonstones!"
Mo Tiange was bewildered.
