Remarried to My Ex-Husband's Nemesis in the 1970s

Synopsis:
When Qin Laidi was young, she had a delicate, peach-blossom complexion, a slender waist, and long dark hair. After falling into the water, she was rescued by Zhao Qingsong, who had returned home to visit relatives. Because of this, she had no choice but to marry into the Zhao family.
Everyone said she was lucky—able to marry Zhao Qingsong, a regiment commander. Her stepson would become a future e-commerce tycoon, and her stepdaughter a famous dancer. As a stepmother, she seemed to have “won at life” effortlessly.
But not long after her husband died, her stepson kicked her out of the house. Only then did she realize that her life wasn’t one of easy success—it was a life manipulated and controlled.
“Marry me, and you won’t have to do anything—just take care of the household.”
Qin Laidi: So I had to quit my much-envied job to become an unpaid nanny.
“Marry me, and give me a soft, sweet little daughter.”
Qin Laidi: So you secretly got a vasectomy and still made me spend twenty years seeking medical help?
“Marry me, and I’ll take care of you.”
Qin Laidi: So on the very day the property certificate was issued, you secretly transferred our shared assets to your son and left me homeless?
Only before her death did Qin Laidi finally understand the scheming of this sly man. Even the person who rescued her back then wasn’t him—but it was too late.
Who would have thought that when she opened her eyes again, she had returned to the very day she fell into the water. Wonderful—this time, she wouldn’t play the cannon fodder!
However—
Her grandmother had already stormed over to the Zhao family to force the marriage.
And she even got the wrong person!
The villagers laughed: Widow Qin must be blind—she ignored Zhao Qingsong, who could become a regiment commander, and instead forced marriage on a fair and delicate little technician!
Qin Laidi took a closer look—
This “little” technician, standing 188 cm tall with sharp brows, bright eyes, and eight-pack abs, would in the future be Zhao Qingsong’s most hated rival—and a renowned wireless technology tycoon holding multiple patents.
And he was the one who truly saved her.
The villagers waited to see her regret it. Her ex-husband-to-be also waited to see her full of remorse. But they waited and waited… until she not only got married, but also had a soft, sweet little daughter—until that daughter graduated with a PhD in nuclear physics…
Qin Laidi: I do regret it—regret not remarrying sooner!
In short, it’s the story of a wireless communications tycoon and a master of traditional Chinese medicine raising their only daughter.
