Su Wanyi, a graduate student in the Department of History, never thought that the carved moon hairpin her grandmother gave her before she died would become the key to traveling through time and space. In the museum, as soon as her fingertips touched an ancient mirror with a hairpin-like pattern, a white light suddenly appeared, and when she opened her eyes again, she turned out to be the concubine of the household minister of the Dajing Dynasty - coincidentally, the original owner of this body was also named Su Wanyi.
The original owner was cowardly, his biological mother died young, and he was like a duckweed in the house. Three days ago, he "lost his footing" and fell into the water, and was left to die in a side courtyard. Without a system or a golden finger, Su Wanyi could only survive step by step with a head full of modern knowledge and the memories of the original owner's grievances. She used modern wisdom to improve her situation, but accidentally got into trouble with Prince Jing Xiao Jue, who was rumored to be frail and sinister.
When they first met, he was sitting in a wheelchair, his plain clothes were as white as snow, his eyes were as cold as ice, and he looked at her like an ant. But when her aunt made things difficult for her, who calmly came to the rescue? When she was involved in the undercurrent of the court, who protected her behind her and whispered "Don't be afraid"?
This is a "Great Peace" that has not been recorded in history books. The court is turbulent and the aristocratic families are intertwined. Su Wanyi gradually discovered that her arrival was quietly rewriting history, and that the seemingly weak Prince Jing hid the ambition and deep love to overthrow the world. When the torrent of fate carries the two of them forward, should she comply with "God's will", or hold his hand tightly and face the unknown ending together?
A moon hairpin connects two generations. She comes from modern times, and he overthrows the dynasty for her. This is a love about survival, growth and two-way running.
