A/N: I made some clarifications in chapter 188 and chapter 190. There are 2 treatments with the Duke of Duance.

The Black Market.
In the past, Rosalind never thought of earning her own gold and building her own wealth.
She had a husband that was a Baron and her Empress sister supported her, giving her everything that she needed. She did not understand how good it felt to earn her own money using her own ability. To be fair though, Rosalind did not think of asking for payment in exchange for treatments in her past life.
This time, however, Rosalind found it addictive. The feeling of looking at all the gold coins that they paid her was simply satisfying, she could not get enough of it. After treating the Duke for the second time, Rosalind got the gold that she had been waiting for.
