Adapted from the classical masterpiece Flowers in the Mirror, the story follows the Fairy of Hundred Flowers as she attends the Queen Mother's Peach Banquet. Due to declining Change's proposal to make all flowers bloom out of season, the two get into a verbal dispute and make a wager. Later, Wu Zetian (the Mortal Incarnation of the Heart-Moon Fox) gets drunk and issues an imperial decree urging the flowers to bloom. Compelled by the imperial command, the flower fairies bloom prematurely against the rules, while only Peony holds back and is exiled to Luoyang. Implicated by oversight, the Fairy of Hundred Flowers, along with a hundred flower fairies, is banished to the mortal realm to undergo trials. Ultimately, the Fairy of Hundred Flowers reincarnates as Tang Guichen, initiating a grand epic of celestial-mortal entanglements, destined fate, and women's talent in the mundane world.
