Lin Chen held the map in his hand, it felt heavy, seeming to be made from the hide of some animal.
Unfolding the map, Lin Chen examined it carefully.
There were mountains and rivers, but the map mainly recorded the internal structure of the cultivation ruins.
This included three major caves, four Medicine Valleys, and a main hall.
"Hmm, the map of the interior of the ruins is quite detailed... but the problem is, where are these darn ruins?"
Lin Chen was somewhat speechless.
Knowing the arrangement within the ruins was indeed crucial, but it was useless if the location of the ruins was unknown!
"However, these ruins are very likely within the borders of Yanlai Country."
Lin Chen thought to himself.
This was not difficult to deduce; the lucky explorer who entered these ruins had not yet reached the Foundation Establishment Stage, and the letter he wrote had not been sent out.
This indicated he had just finished exploring the ruins not long ago and was probably not far away.
