This article tells an old-fashioned time-travel story. The heroine failed to commit suicide because of her love. She mysteriously traveled through the era of fairy swords, met the demon Zhengzhenglou by chance, and started a long-standing story with her.
(This article uses Fairy Sword 3 as the background. Although some plots from games and TV series are interspersed in it, everything is to make the article more loving. I hope you will bear with me!)
