Li Yao, a retired assassin, woke up one day to find herself transmigrated to ancient times and became a famous shrew far and wide.

With hands on her hips, she wailed loudly. Villagers called her the bane of ghosts, and even dogs would circle around when they saw her.

She had four children, her husband had passed away, and it was a disastrous year, leaving them poor as church mice.

Fortunately, River Bay Village was nestled against a big mountain, with wild chickens, wild boars, wolves, tigers, herbs, spices, corn, sweet potatoes, potatoes… it seemed to have everything.

Rely on the water to eat, and rely on the mountain.

With her skills that exceeded the times, Yao Li quickly became the wealthiest person in River Bay Village.

She was determined to stick to her original aspirations – retire and live out her remaining years in peace.

But as a widow, there were many things at her doorstep.

Her maiden family coveted her wealth; local ruffians lusted after her beauty; the magistrate admired her talents; the prefect wanted to rely on her to build up his political achievements; the scholar admired her literary talent; the chancellor respected her breadth of knowledge…

Wave after wave, wearing down her doorstep.

Even a Prince was amazed by her, finding all kinds of excuses to frequently visit and neglect his palaces.

Li Yao adapted to the circumstances, sparring back and forth, just wishing her retirement life would remain undisturbed.

But unknowingly, the world was changing because of her.

"When will people understand.... I'm only half insane?"
