The words Lilith just said confused Bai Zemin immensely. He had many questions he wanted to ask her but that he knew would probably not be answered in their entirety if they somehow or other involved matters against the rules; for example, Bai Zemin knew that if the information he needed to know contained something that would prevent him from taking a certain path then she could not tell him anything as that would be involving herself in his immediate fate very deeply.
However, even without asking questions, there was something that Bai Zemin understood after hearing the words 'Ancient Ruins'.
Where there were ancient ruins, treasures were a given!
Regardless of the era or age, whenever a ruin from ancient times was found then that country and eventually the entire world was bound to benefit in some way or another!
