Zhai Jing was an educated woman living in the modern world, until an accident caused her to be reborn in an ancient era marked by a complicated history. This world had once endured a period of cultural repression. Its people were conservative, and feudal rules were strict.
Longing for an ideal age of prosperity, Zhai Jing draws on her modern knowledge to try to break the status quo and create an entirely new society. But her actions threaten the interests of conservative feudal forces. Led by reactionary ministers at court, her opponents fear she will upset the existing balance of power and obstruct her at every turn, trying to stop her from spreading new ideas and developing new things.
As a woman constrained by feudal rules, Zhai Jing faces countless restrictions. Each time she tries to share modern knowledge, people accuse her of spreading heresy, and she is met with suspicion and rejection. Yet with her uncommon resilience and intelligence, she struggles forward through adversity.
As time passes, cultural repression grows more severe and the people's thinking becomes increasingly rigid. Zhai Jing knows she must bring about change before society becomes completely fixed in its ways. But as she works to advance her cause, her opponents betray and exploit her, repeatedly undoing what she has achieved. She faces a crisis of trust, while those around her leave one by one, misled by false impressions.
Still, Zhai Jing refuses to give up. She works to clear up misunderstandings and win the people's support, while matching wits with her enemies. In the end, can she overcome every obstacle and build the ideal age of prosperity she dreams of? The answer remains uncertain.
