After My Younger Half-Sister and I Switched Betrothals, She Cried Herself Unconscious in the Slums

[Medical skills + feel-good revenge + a powerful heroine who hustles for money and takes her whole family along + business + a legendary songstress]

A battle-hardened prince confined to his sickbed and a clear-eyed village beauty: married first, falling in love later, fighting to survive against all odds.

As the eldest daughter in her family, Chen Qianqian has no skill at music, chess, calligraphy, or painting, and she can't compare with the noblewomen of the capital. But slaughtering chickens, butchering sheep, and doing hard labor are right up her alley. She's the toughest girl in the village, does all the work usually done by men, and can support her entire family.

Her stepmother accepted two marriage offers without finding out the details. One was to become a princess consort buried as a funeral sacrifice, and the other was to become a wealthy merchant's concubine.

Her half-sister was lazy and greedy. When she heard that the man she was supposed to marry would be buried as a sacrifice, she refused at all costs and insisted on switching marriages with Chen Qianqian. She stole Chen Qianqian's marriage.

After the swap, the younger sister married into the merchant's household as a concubine, but was thrown out in less than a month and became a laughingstock in the village.

Meanwhile, the elder sister became the War King's consort and enjoyed a lifetime of wealth and glory. When one person rose to power, even her relatives benefited.

The younger sister was insanely jealous. She knocked on her brother-in-law's door every day, trying to steal him away, until the whole city was laughing at her!
