I’m Bold! I Had My Way with the Prince, Then Ran Away!

Transmigration + space + building an army in ancient times + a heroine who never takes abuse + feel-good story + infrastructure building + the heroine is amazing

Xu Manning transmigrates into a book, becoming the cannon-fodder villainess in a novel called The Emperor's Gambit.

According to the original plot, Xu Manning is hopelessly in love with Prince Duan, but he deceives her for both her heart and her money. In the end, her entire family is sentenced to execution.

On the day she transmigrates into the book, she is framed and ends up sleeping with a man. She later learns that he is Prince Heng.

Prince Heng is the god of war of the Yan Kingdom, a noble and austere man who commands the military.

So she decides to join forces with him to destroy Prince Duan.

When she sees Prince Duan again, she says, "What a nuisance. I wouldn't date you if you were the last dog on earth."

She lashes out at scumbags and stabs her enemies.

She whips out pistols and cannons and shows off their power.

The pistols shock the people of ancient times and earn her many admirers.

Later, her ambitions grow, and she simply builds an army of her own.

When the emperor displeases her, she marches her army into the palace, overthrows the tyrant, and takes the throne herself.

One day, a doorway through time opens, and she returns to the modern world.

The lovesick Prince Heng has red-rimmed eyes from waiting up all night. "Xu Manning, come back."

A long novel. The pistol does not appear until chapter twenty.

The heroine is serious about building her career.
