「A hundred thousand years ago.」
Ye Yun had many beautiful companions, each one of unparalleled beauty, enough to captivate nations. But when it came to swordsmanship, Liu Yiyi was undoubtedly number one. Liu Yiyi's Sword Dao Talent was exceptionally high, and she often enjoyed sparring with Ye Yun. She could also be considered a Sword Infatuation. Because they often sparred, Ye Yun and Liu Yiyi developed a deep understanding of each other, and together they created a set of Swordsmanship techniques—the very Swordsmanship inscribed on the Sword King Stone: the Nine Heavens Lotus Sutra.
