Fairy Nan Yi was clever and gifted from a young age. She and Xuan Qing, the Crown Prince of the Celestial Realm, were deeply in love, and once they came of age, they were to be married.
Xuan Qing ascended the throne as the Celestial Emperor, and Nan Yi married into the Celestial Realm, becoming an immortal consort. Also marrying into the Celestial Realm was a mortal woman named Qin Zhi, whom Xuan Qing had brought back after undergoing a trial in the mortal world.
After their wedding, Xuan Qing neglected Nan Yi at every turn and showered his affection solely on the mortal woman.
In the war between immortals and demons, Nan Yi sacrificed herself to Heaven, her body and soul vanishing without a trace. Qin Zhi became the Celestial Empress, and the imperial couple lived in harmony. The Three Realms enjoyed peace.
When Nan Yi opened her eyes again, she discovered that she was Shen Nanyi, a junior disciple at Xuantian Palace. Her master was kind, and her senior brothers doted on her. Given a second chance at life, Nan Yi wanted nothing more than to eat her fill and laze around, but it turned out she had to complete missions to keep the life she had stumbled into.
Her mission: win over Jiang Guqi, a disciple in her sect whose parents and master showed him no love, and whom everyone considered a bringer of bad luck.
She had to stop him from turning evil, growing powerful, and becoming the ultimate villain.
