Transmigrated as a Palace-Intrigue Extra? My System Is a Bit of a Joke!

Su Yurou was a miserly modern office worker, the kind who'd reached the highest level of penny-pinching. Then she transmigrated into a palace-intrigue novel as a disposable young concubine who wouldn't survive three chapters...

Luckily, she got bound to a System.

An ordinary family background, enemies on every side, and the System even charges for its services? Should she just lie flat and accept her fate, or... turn penny-pinching into an art form? Su Yurou's answer: Spend money? Not in this lifetime! Just watch me fleece you instead!

Years later, she looked at the System, stripped bare and spitting out streams of corrupted code, and her former enemies trembling on their knees before her. [The entire harem was actually surviving on the relief coupons she handed out?!]

She was a corporate drone in the modern world. You think she wouldn't be one in ancient times? No romance, just business... (hopefully).
