Shen Yan, a cunning and powerful modern man, transmigrates into the Great Feng dynasty as Prince Jingyuan. He commands three thousand Snow Dragon Riders and wields immense power, and he even becomes the husband of Princess Huaiqing. Incredibly handsome and unfathomably clever, he calls Wei Yuan his brother and earns the Imperial Astronomer's favor. He had hoped to use his foreknowledge from transmigrating to make up for past regrets and protect those he loved, but before long he finds himself caught in an ever-growing romantic predicament.
Huaiqing's cool, probing advances, Mu Nanzhi's tender dependence, Luo Yuheng's mutual respect between powerful rivals, Lin'an's spoiled persistence, Chu Caiwei's innocent devotion, Li Miaozhen's chivalrous affection, Fuxiang's confidante-like companionship, and Princess Pingyang's adorable pursuit... Each of these beautiful women has her own charm, and they all fall for him.
The court is a treacherous maze of political intrigue. He asserts his authority through the tax silver case, consolidates his power through the Sangpo conspiracy, puts down the rebellion in Yunzhou, and foils the Buddha's schemes, dancing on the edge of a blade. Meanwhile, undercurrents swirl in his romantic entanglements. Jealous bickering is part of daily life, and tent-side confrontations, accidental catches in the act, and moonlit contests for his favor follow one after another. He keeps several women close while proceeding with utmost caution, trying both to soothe their jealousy and protect the Great Feng dynasty.
Fighting alongside Xu Qian'an, extending Wei Yuan's life, and helping Huaiqing ascend the throne, Shen Yan stirs up a storm in Great Feng. On one side lies the ambition to wield power over all, and on the other, an impossibly tangled web of love. In this dual struggle of politics and romance, can he have it all, make every regret right, and find a place for all the love he has been given?
