Shen Weixi, a modern archaeologist, unexpectedly transmigrates to the turbulent Great Jing Dynasty and becomes a descendant of the previous emperor, whose family was wiped out in the Jingnan Rebellion. Burdened with a blood feud and her family's final charge, she is forced into the treacherous struggle for power within the palace.
To clear the late emperor's name, she secretly takes control of Rouge, the secret-guard System left behind by her ancestors. Using modern thinking and archaeological methods, she gathers hard evidence in the tightly guarded imperial court. Her greatest opponent is the young emperor Yuwen Yuan, who seized the throne with an iron fist and is suspected of regicide. Between court and harem, the two engage in one perilous contest after another, at once enemies and allies. Suspicion and attraction go hand in hand, as murderous intent and affection grow side by side.
Then the layers of mystery are swept away, and a truth capable of overturning everything crashes down upon them. The hidden story of the twins' birth and the carbon-14 dating of the coiled-dragon jade seal bind them together inescapably: the tyrant she swore to overthrow is her own brother, bound to her by blood!
