- “Immortal destiny has appeared, and I have an Immortality Illumination Vine. I can see my path to Immortality, and I will succeed!„
She is first seen during the opening of the Immortal Ancient Daoist Rite Temple where she encountered her arranged fiance, Meng Hao — a fact that neither of them are aware of. Due to various misunderstandings, they both got off the wrong footing and thus didn't have quite a good impression of each other. She would later sympathize with Meng Hao when they both learned of their engagement.
Seen as an extraordinary woman, she is a beautiful girl though only considered second to Fan Dong'er in terms of beauty. She has a glittering green willow leaf mark on her forehead.
Even amongst the Chosen of the Ninth Mountain and Sea, she is considered one of the strongest and hence has quite a reputation among her peers and elders. She is also a Divine Daughter of the Li Clan.
She used to play with Meng Hao during their childhood, before he was left on Yunjie County. The latter used to bully her, even setting her hair on fire once which resulted in her hating the child Meng Hao.
Li Ling'er, along with most of the Chosen of the Ninth Mountain and Sea, made her first appearance during the opening of the Immortal Ancient Daoist Rite Temple in South Heaven.
Li Ling'er, along with most of the Chosen of the Ninth Mountain and Sea, attacked Meng Hao to take the command medallion given to Meng Hao by Fang Xiufeng, which allows one to become a conclave disciple of the Immortal Ancient Daoist Rite Temple. He was the first among all the Chosen to attack Meng Hao, and the second one to be captured by Meng Hao, after Taiyang Zi.
Meng Hao trapped many of the Chosen into his bag of holding and had them write promissory notes to him, essentially extorting money from them. After giving Song Luodan a good beating, he finally agreed to sign the promissory note.
During the East Sun Ascension event, Li Ling'er reached 174,000 meters.
Meng Hao and Li Ling'er were set to be beloved since they were born. However, he only loved Xu Qing and, thus, was unwilling to go through with it. Using Patriarch Reliance, Meng Hao managed to escape from Fang Shuodao, his marriage with Li Ling'er, and Planet East Victory.
At the same time, Li Ling'er also escaped from the Li Clan as she was also unwilling to marry Meng Hao. On the way, she encountered Outsiders and was chased into the Ruins of Immortality. There, she was saved by Meng Hao from being raped and then killed.
Later, Paragon Sea Dream decided to take her as her disciple, presumably due to her bearing a striking resemblance to someone Sea Dream used to know.
As one of the 33 Chosen handpicked to go to the 33 Hells, she was one of the few who chose to sacrifice their life force in order to gain a cultivation base equal to that of an Imperial Lord's. She only had a single 60-year cycle left.
Like Wang Youcai, she was able to live past a single 60-year cycle. After the death of Paragon Sea Dream, she continued to execute and fulfill the dead Paragon's wishes. She founded the Sea Dream Association, now a powerful sect within the Mountain and Sea Butterfly.
While Meng Hao was traveling around the Mountains and Seas and seeing how everyone was doing after reincarnating he says that Li Ling'er became the sole Legacy disciple of a powerful sect.
