Transmigrated into a Book in the 1970s: My Wife Is Sweet and Cunning

[Sweet romance + world inside a book + talented people + supernatural powers + building a fortune]

The System rewards Chu Yanxi with a trip transmigrating into a book because she has read too many novels? That's just... ridiculous!

Since she's here, she decides to lie flat! She spends her days tormenting scumbags and watching the drama unfold, enjoying a carefree little life. But what's with this awful man?

The first time Qiao Beicheng meets Chu Yanxi, who's gone to the countryside, he thinks: Why is this woman here? No, I need to keep my whole family away from her, or we'll all end up miserable.

Later, Qiao Beicheng sees the woman surrounded by his family, who are fussing over her, and his handsome face takes a proper beating. The next second, he squeezes his way in and stakes his claim: “She's my wife! Mine!”

[This is my first time writing a story set in the 1970s. Please overlook any implausible details. It's a world inside a book or a parallel world, so don't overthink it!]
