The City Lord wasn't surprised he knew about this civilization, and nodded.
Cao Xing's pupils suddenly contracted.
To be honest, he was very curious about this ancient civilization.
The ancient weapons on him partly looked like the hot weapons on the Blue Star, but the technology level far surpassed that of the Blue Star.
It can be imagined that this civilization once developed to a quite prosperous level on the continent.
However, such a vast civilization silently perished, and no one even knows what happened.
This also made Cao Xing sigh, this vast continent holds too many secrets!
The City Lord continued: "Few know about this city, and those who qualify to enter are strong beings."
"Over the years, they've been secretly exploring this lost royal city."
"But after so long, not even one percent of the whole lost royal city has been explored."
"But just this one percent has brought the powerful beings astonishing rewards!"
