"In that case, I can help."
A young girl with light brown skin like amber squeezed through the crowd.
"Diao?" Li Ang was surprised by the arrival of the Ancient Witch Maiden.
Noticing the crowd, Diao nodded awkwardly, seeming embarrassed by her perpetually out-of-place attire.
She whispered, "Li Ang, I'm here to find you."
"There's something going on here." He wasn't sure what she intended, but the current matter needed resolving first.
"Mm, I heard half of it; I can help with this mud wall."
Diao looked at Li Ang and Zoe, then at the owner of the mud wall: "The traces you speak of, accumulated over time, are actually a result of the magical power repeatedly catalyzing the natural accretion process of the mud wall, creating something similar to strata separations. Because Li Ang precisely controlled the Power of Nature, the mud wall formed all at once, so those traces are absent."
