In the 1980s, I Swapped Marriages and Snatched the System; Sign-In Rewards Me with a Rugged Big Shot

[Historical era + sign-in System and space + building wealth + face-slapping + raising an amnesiac tycoon from Hong Kong into a rugged man]

"Hmm? You knocked me unconscious, made me lose my memory, and took advantage of me. How are you going to pay for that?"

Su Nianhe was cornered against a wall by a Hong Kong tycoon who had just regained his memories. She touched her belly and explained guiltily:

"I really didn't do it on purpose..."

Only after Su Nianhe died did she learn that she was merely a cannon-fodder foil in a story set in a bygone era.

Her family had favored her older sister, the heroine, since childhood. The son they had raised for over twenty years was actually her sister's, and even the golden finger that should have belonged to Su Nianhe had been stolen by her sister.

Even the only man who had firmly chosen her in the marriage swap eventually told her, "I regret it..."

Reborn on the day of the marriage swap, she gives them what they want!

She takes back her golden finger, cuts ties with her family, heads to Pengcheng, collects scrap, builds a business, and grows rich along the way...

But what's with the amnesiac man she picked up in a ditch?

How did he suddenly go from a clingy, rugged man to a refined and elegant heir from Hong Kong?

And that scumbag former husband from her past life: Didn't she give you what you wanted? Why do you keep... regretting it?

Regret, regret. Do you think you're a broken record? Is that the only thing you can say over and over?
