Demon Child Nezha: I Descended to Become the Third Prince's Big Sister

[A spin-off of the Demon Child Nezha series and The Tale of Ao Bing + Past and Present Lives + Ao Jia Romance + Side Couple: Nezha and Ao Bing]

PS: There are tons of personal headcanons and plot holes. I'll make changes to the original story of The Tale of Ao Bing based on my own interpretation, while trying to stay as close as possible to the movie.

For violating the laws of Heaven, the heavenly general Cangyu Star Lord was banished to the mortal realm to suffer the cycle of reincarnation. He was reborn in the womb of Yin Suzhi, wife of Li Jing, the garrison commander of Chentang Pass, as Li Lingshuang, the twin sister of their second son, Muzha.

Though she was frail, often ill, and of only average talent, unable to join her elder brothers Jinzha and Muzha in cultivating immortality, Li Lingshuang still had plenty to keep her busy in her mortal life.

For the first twelve years, she immersed herself in medical texts and worked herself to the bone mastering medicine. After that, she had to help her mother raise her younger brother Nezha, who should have been reborn as the Spirit Pearl but was accidentally reincarnated as the Demon Orb.

The siblings were very close, but that didn't make the pain of being exhausted from raising a child any easier.

While out gathering herbs one day, Li Lingshuang met a strange young man with golden hair and differently colored eyes. He was gloomy and taciturn, yet the instant their eyes met, an overwhelming sense of familiarity surged through her, as though it had come rushing from a thousand years ago.

“Who... are you?”

“I am Ao Jia, the eldest prince of the East Sea Dragon Clan, known as the Golden Dragon of the Waves. May I ask your name, senior?”

“You needn't call me senior, Your Highness. I'm Cangyu Star Lord of the Heavenly Court, sent to the mortal realm to slay the demon causing trouble.”

Previous life: Cangyu Star Lord, heavenly general × Ao Jia, the Golden Dragon of the Waves and eldest prince of the East Sea

Present life: Li Lingshuang, daughter of the Li family of Chentang Pass × Ao Jia, a wandering young man who has lost all his memories

“In this life, we loved and hated, through every right and wrong. If we meet again in the next, may we always be together, just as we are now.”
