After Transmigrating into a Book, I Played Sweet and Innocent My Way to Becoming Empress

[Transmigrates into a book + palace intrigue + satisfying revenge + sole devotion + no System]

She transmigrates into a book as a sacrificial palace maiden, with only three months left to live.

No golden finger. No System prompts.

She relies not on luck, but on her brains.

She acts obedient, plays the victim, and pretends to be weak, turning the harem upside down.

The Noble Consort hates her, the Virtuous Consort schemes against her, and the Empress Dowager wants her dead.

She smiles and lowers her head, then turns around and sends her rivals to their doom.

At first, the emperor is simply curious:

"Why is this woman different from the others?"

Then he begins to feel for her:

"Whoever lays a hand on her will pay with their life."

In the end, he falls for her completely:

"I don't want the six palaces. I only want you."

From sacrificial pawn to the emperor's sole beloved, she only had to get one thing right:

She really is serious about acting sweet and obedient.
