The Sky Is Falling! I Became a Wicked Widowed Sister-in-Law and Got Bound to a Harem System

[Transmigration into a Book + Farming + System + Harem Rivalry Showdown]

Su Yunyun transmigrates into a book, becoming the wicked widowed sister-in-law who, from the start, is about to sell off her husband's younger sister and ends up chopped to pieces and fed to the dogs.

To stay alive, she is forced to bind herself to a "Player System."

She thinks she only has to farm and make money honestly to survive until the ending, but the System goes haywire:

[Ding! Smile at the village head's young scholar within three seconds, or pay a fine of 300 taels!]

[Ding! Have a candlelit dinner with the heir of the Duke of Zhen Guo, or pay a fine of 500 taels!]

Su Yunyun is forced into "player" mode, playing along with one man after another.

But who would have guessed that the most terrifying, stone-faced King of Hell would keep a closer and closer eye on her?

One night, Chu Yi corners her in her room, his eyes full of madness and restraint. "Your romantic luck has been pretty good lately, sister-in-law."

Su Yunyun trembles. "How about you give me a divorce letter and throw me out..."

Chu Yi grabs her chin and kisses her fiercely. "Sure. I'll throw you into my room."

Content warning: The heroine is focused on making money and building her career. She's forced into conquest at first. The hero is extremely protective and unhinged, and later he'll have to chase his wife the hard way!
