"Murals? These small things have that ability?"
Pointing at the crystal crabs, Feng Yuan looked incredulous, and Veronia snorted lightly and said,
"That's uncertain. The situation here is very strange. There are clearly numerous murals, yet no signs of human activity. From the tenth level onwards, each layer's murals are different."
"Mine tunnels painted with murals?"
Agunas looked skeptically at Veronia. No matter which civilization, there is no precedent for this; at least, there is no such record in the annals.
"Not mine tunnels, more like ancient passages, primarily structured with bricks and stones. I think Tamur should be more familiar with this."
"I don't know, it's just the prevailing method of that time."
Tamur shook his body lightly and said coolly, Feng Yuan smiled and said,
"So, the mine tunnel isn't everything. Wait? Agunas, is there any record in the research materials about such changes in the mine tunnels after a certain number of layers?"
"No."
