“You want me to become a eunuch on my wedding day?”
Rumor has it that the Great Xia dynasty has two peerless beauties. The elder sister, Su Qingfeng, is a spirited martial arts devotee, while the younger, Su Qingyue, excels at music, chess, calligraphy, and painting. Yet both have been betrothed to Gu Yuan, a wastrel from the Prince of Zhennan's household.
On their wedding night, the emperor issues an edict forbidding Gu Yuan from consummating the marriage.
The capital's number one beauty, his new wife Su Qingyue, has her heart set on her first love. The emperor schemes against him, and the Chancellor's household humiliates him. All of them want to use the Prince of Zhennan's family as a stepping stone to test the waters for curbing the power of the vassal princes.
Everyone thinks Gu Yuan, a useless wastrel who has yet to begin martial arts training at the age of twenty, will kneel in tears and accept the edict.
“Eunuch, do you really think the eight hundred thousand cavalry of the northern frontier can't lift their blades anymore?!”
Gu Yuan tears up the secret edict on the spot, kills the old eunuch who “falsely proclaimed” it, and forcibly consummates the marriage.
The third prince, his wife's first love, barges into the Prince's residence to take Su Qingyue away? Gu Yuan strikes, and the prince is castrated on the spot!
The emperor summons him? The Prince of Zhennan personally leads his cavalry back to the capital to apply pressure, forcing the Son of Heaven to admit that the eunuch forged the edict and that the third prince got what he deserved!
From then on, after consummating the marriage and awakening the Yin-Yang Sacred Body, Gu Yuan stops hiding the fact that dual cultivation makes him stronger.
He brings all his literary and martial talents to bear, subduing Su Qingfeng, his twin sister-in-law who has returned to the capital at the head of an army to settle the score, and taking her on as a blade in his service.
From cold, glamorous female generals to resentful women locked away in their chambers, from the supreme emperor to the palace's martial experts...
Gu Yuan turns the capital upside down.
“If you can sit on the dragon throne, then so can I!”
