Disguised as a Man, I Set Out to Conquer the Cold Princess

[Two female leads + Transmigrate into a book + Woman disguises herself as a man + No System, no golden finger]

Conquering the aloof princess, only to get conquered instead?

Ji Mingyuan transmigrated into a book. Transmigrating into a book isn't scary, but who gets dropped right into their enemy's arms when they do?

Although the emperor had already arranged her marriage, the original character in the book died at the hands of the princess Shen Qingcong and her destined partner.

After spending her whole life in the real world pretending to be her nephew's aunt, Ji Mingyuan decided to take the initiative and conquer Princess Shen Qingcong.

As the story unfolded, Ji Mingyuan realized that the original plot had changed dramatically due to the butterfly effect. Having read only a small portion of the novel, what was she supposed to do now?

Shen Qingcong, before learning Ji Mingyuan was a woman: I'm definitely calling off this engagement! Get lost! Maybe you're just pretending to be weak to catch me off guard!

Shen Qingcong, after learning Ji Mingyuan was a woman: This is getting interesting.

There may be a modern-day arc later on.
