Period: I'm a Butcher, and from the Start I Married a Rich Heiress

[Period setting + big shot + System + heiress from a capitalist family + Cao Cao] One moment, Jiang Yan is attending his company's IPO celebration banquet. The next, he transmigrates to the 1970s and into the body of a butcher's son who shares his name. Dumped by his fiancée from the start? He awakens the Daily Intelligence System in an instant! Today he finds his father's secret stash; tomorrow he gets a hundred-jin fat pig for free. While others are still struggling to get enough to eat, Jiang Yan has already led his three older sisters into a comfortable life. Just when everyone thinks he'll inherit the family business and spend his whole life slaughtering pigs, he instead saves a powerful capitalist who has been framed. Everyone mocks him. “Jiang Yan's gone crazy! He's actually getting involved with one of the ‘Black Five Categories’!” Then he marries the big shot's breathtaking daughter, opens the county's very first private enterprise, and becomes a trailblazer of reform and opening up... The ones who once treated you with indifference now can't even hope to reach you! See how a humble butcher's son uses intelligence to stir up the world,
