Ye Chuyan transmigrated into the pampered but unloved legitimate daughter of a duke's mansion, who had been struck off the marriage register by the old emperor for causing a scene before the throne. The moment she opened her eyes, she was forbidden from ever marrying, becoming a laughingstock throughout the imperial capital!

After her scumbag father at the duke's mansion failed to beat her to death, he disowned her and threw her out. But she simply turned around and seduced Helian Yu, the newly appointed crown prince.

Beneath the red bed curtains, she loosened her robes, her eyes alluring.

"I won't marry, and you won't take a wife. We each get what we need. Your Highness, don't you want to give it a try?"

Helian Yu kept a stony expression, but his body told a different story.

Three years later, after the crown prince ascended the throne, the first thing he did was execute the entire duke's household...

[Bleep bleep bleep! Plot alert: Host, in six months you will die in childbirth along with your baby. Break out of your predicament and find a way to stay alive!]

Die in childbirth along with her baby? How exciting!

Then she'd better find the lecher who would get her pregnant, and then...

Snap! Break his neck!

Unfortunately, her fertility was just too good. Before she could even lay a hand on the lecher's neck, she turned a corner and was dragged into an alley.

She got pregnant in one night, and the lecher turned out to be the crown prince?

Wouldn't that make this child the emperor's eldest grandson?

Ye Chuyan stroked her belly, troubled. The sinister crown prince immediately went full domineering CEO: "Woman, give birth to him, and you'll be the future empress!"
