After Our Divorce, the Empress Begged Me to Become Regent

After returning in the latter half of his life, he finds himself a live-in son-in-law.

In a flash, he becomes the proprietor of a pleasure house.

So be it.

A pot of rough wine, a couple of tunes, and a few beautiful confidantes. He'll spend the rest of his life in idle pleasure.

But then...

His father-in-law at court asks him to solve cases, friends in the martial world beg for his help, and people from every walk of life, from officials to nobles, all come to this pleasure house to gather intelligence.

One day, even the highest authority in the empire comes in person, drawn by his reputation.

Empress: Cai Lang, I hear you want me to be your most beautiful courtesan?
