They say that atop Juejian Peak lives a genius sword immortal named Shi Nian. When she joined Wenjian Peak, the sect-founding patriarch's immortal sword, Chunjun, chose her as its master. None of the elders dared take her as a disciple, so she practiced alone on Juejian Peak. No one knew her character or how profound her cultivation was.
Li Wanyuan, the empire's eldest princess, was found to have a spiritual root and joined Juejian Peak. The ancestral divine sword Chixiao chose her as its master, making her Shi Nian's officially recognized junior sister.
The divine swords in this book are inspired by famous ancient swords. It's not just a case of similar names anymore (sliding away!).
