[Transmigration + Alternate History + Crown Prince + Kaiyuan Golden Age + Devoted Couple]
When history PhD Xiao Xuan opened her eyes, she had become the legitimate eldest granddaughter of Xiao Song of the Lanling Xiao clan, and Chang'an's foremost talented woman, freshly pulled from Qujiang Pool.
Chang'an in the twelfth year of Kaiyuan was alive with brilliant stars:
Zhang Jiuling, the man who wrote "The moon shines over the sea," was still only a Secretariat Drafter;
Li Bai had just left Shu. The poet who wrote "Heaven gave me talent, and it must be put to use" had yet to become famous across the land;
Du Fu, the future Poet Sage who would write "Though the kingdom is broken, its mountains and rivers remain," was still a young boy;
Wang Wei was famed throughout the capital for his mastery of both poetry and painting;
Princess Yuzhen was cultivating the Dao outside the city, Li Longji was in his prime, and Zhang Yue was chancellor, with his remonstrations heeded.
She knew how their lives would unfold. She also knew that all this splendor was merely the light of the night before a chaotic age.
But no matter how many history books she searched, she found only a hundred or so words about one man:
Li Ying, Crown Prince to Emperor Xuanzong of Tang, was deposed and reduced to a commoner in the twenty-fifth year of Kaiyuan.
That ending had already been written.
Except for her.
She was the only person in this world who had read the ending.
She had thirteen years to rewrite that line with her own hands.
She had only meant to record his life, but instead she traveled across the mountains and rivers of the Tang with the Eastern Palace mission: surveying the household registers of Hexi, opening a thoroughfare through the Shu Road, promoting education in Lingnan, and bringing disaster relief to the northeast. Between the court and the frontier, they would safeguard the Kaiyuan Golden Age together.
