The miniature Freemasons' symbol clearly stamped on the silver coin suddenly made things more interesting.
Apparently, in addition to the former Freemason member who left the previous information, another group of Freemason members had been here.
However, this batch of Freemason members didn't know the discovery of the previous member, so they left after taking the murals in the obviously worse Solar Cave.
The reason why this more rudimentary cave was discovered by the later parties is that this cave is closer to the outside than the previous cave, so it was found first.
Since historically, no one has temporarily discovered the connection between the two Solar Caves, those who found this cave later did not continue the search, but instead, preserved the more grand Solar Cave.
