Rong Xiu looked at her with a glint in his deep eyes. His thin lips curved slightly as he said indifferently, "There are still quite a lot of books in the Sky-Cloud Empire. Although the world knows very little about the battle back then, there are actually some related rumors that have been recorded and passed down. It's not difficult to find out."
Chu Liuyue nodded in understanding. That's true. The Sky-Cloud Empire has stood in the God Residence Realm for tens of thousands of years and has a deep foundation. It's normal for them to know something about this.
Shangguan Jing knew very little about this place, mostly because he was an outsider. Naturally, he couldn't compare to Rong Xiu's background.
