The Madman of the City

As a live-in son-in-law, his life is utterly miserable. His mother-in-law and her family treat him like a useless nobody and scorn him at every turn! Unexpectedly, an act of kindness grants him the power to decide who lives and dies and determine the causes and consequences of people's fates. From then on, wealthy merchants from every corner and powerful figures from far and wide come begging on their knees to win his favor!
