Ex-husband, how could you not know I'm a divine doctor?

Synopsis

buried my god-tier surgical skills to be a docile wife, only to be dumped by my cheating ex for his mistress and their illegitimate son. When his dying boy needed my exclusive treatment, he hurt my operating hand out of malice, costing the child his life. I exposed all his sins, leaving him and his vicious family drowned in endless regret.
