Be Good! Don't Make Me Take Concubines, We Don't Do That Here

[Ancient-to-modern transmigration + devoted husband + devoted wife + strong male lead + heroine thinks she's weak, but she's terrifyingly powerful]

Before transmigrating:

Her grandfather's achievements made him a threat to the emperor, and he died by suicide.

Her father and brothers were sent to defend the frontier in a crisis, and none of them survived.

Zeng Li was held hostage to keep her family's military power in check. She was married into Prince Qi's household, blocking his path to the throne, and beaten every day and punished every night after the wedding.

After transmigrating:

Zeng Li has just one wish: that her husband doesn't hit her.

So she follows the rules for wives and obeys her husband in all things.

Whenever something happens, she has a three-step plan: kneel, bow, apologize.

Life couldn't be going better.

She has few talents, except for a little music, chess, calligraphy, and painting. She also has martial arts skills that were suppressed with poison by Prince Qi, but they're gradually returning.

Then one day, she discovers that even her modest skills can make money. In this new era, women can leave home and roam freely through the world, so she gets enthusiastic about taking on all kinds of secret identities, earning both fame and fortune and filling her pockets to the brim.

The only thing that troubles her is that her husband, surrounded by beautiful women, keeps complaining that she's never jealous and acts too much like a proper wife. Boo-hoo, I'm devastated. Is even that wrong?

[A heroine who grows stronger, skilled in music, chess, calligraphy, and painting, as well as martial arts]
