The thoughtful, calm and thoughtful time-traveling heroine VS the wise prince who is very good at martial arts (in my case the heroine is absolutely powerful)
Yu Mingshi traveled through time, and as soon as he opened his eyes, he arrived at an era that was beyond his awareness. This was a feudal era, and she tried to find an era in history that matched it in her mind, but she found that there was none.
She worked hard to play the role of a famous lady in this feudal era that is not in history. Traveling to a new world is not a wonderful thing. She can only try to keep her modern will from being worn away. And she was also involved in a whirlpool of power, and the story unfolded. It's not a particularly cool piece of writing, but it's still pretty cool.
Concept: A heroine who relies on her brains to work well
