In her previous life, she spent her entire fortune helping a scumbag ascend the throne.
In the end, her child was killed and her beauty destroyed.
As she lay dying, the beauty in the scumbag's arms smiled dazzlingly. "A merchant's daughter thinks she can be empress?"
Reborn, she returns.
Her stepmother is vicious? Hang her up and beat her!
Her stepsister is heartless? Beat her in all sorts of ways!
She has no powerful allies?
She opens one shop after another until she's richer than the state itself.
Her stepsister becomes a consort and bullies her?
She builds an army in retaliation and supports a eunuch as emperor.
On the day the land is finally at peace, he corners her against the wall, dressed in imperial robes. "My empire needs an empress."
She sneers. "You're a eunuch!"
Before she can finish, he seals her lips.
The next day, she clutches the wall and cries. "That was brutal!"
