Calculating All of Chang'an

Shen Zhiwei, a modern finance professional, transmigrates to the Great Sheng dynasty.

While others transmigrate to farm, fight domestic battles, and fall in love, she takes an abacus and a ledger to Jiangnan, auditing the books and saving businesses on the brink of bankruptcy.

A pharmacy, a dye house, a rice shop…

At first, she thinks she's only saving one business after another.

Then a string of business scandals unfolds: shopkeepers disappear, firms go bankrupt, and owners flee with their entire families. Every business caught up in the cases has had its books examined by her.

Pei Jinghuai, sent south to investigate, begins keeping a close eye on her as well.

As their investigation deepens, the two gradually discover that someone is secretly manipulating trade routes, money, and credit, able to make a century-old business flourish one day and perish the next.

What truly needs to change has never been any single business.

It's the commercial rules of the entire Great Sheng dynasty.

This is a battle of money, commerce, and human nature.
