"Elder Huo, you keep talking about the 'Sword Heart,' but what on earth does it actually refer to?" Duan Lingtian asked, puzzled.
"It's hard to explain the Sword Heart in specific terms. You just need to know that it represents the peak of the Sword Dao achievable within a secular plane... In the myriad realms, countless people give birth to a 'Sword Heart,' but almost all of them do so within the myriad realms themselves, which is nothing special."
"After all, the cultivation environment and resources in the myriad realms are ridiculously good. Unless they are utterly inept sword cultivators, almost anyone can give birth to a 'Sword Heart' there."
