After the infamous Emperor Ling of Chen, a notorious ruler in history, suddenly died in his sleep, the flustered World System grabbed the soul of a modern office worker who had worked so much overtime she'd lost her senses and shoved her into the tyrant's body.
If she completed the historical mission of a notorious ruler, she could return to modern society and collect a huge fortune.
The office worker was overjoyed: Wasn't this just a chance to live a life of luxury and indulgence twice over?
Let's see what a tyrant needs to do:
Conscripting one hundred thousand palace maids by force?
Living in extravagant luxury?
Practicing alchemy in pursuit of immortality?
Imposing excessive taxes and levies?
Launching massive construction projects?
Favoring eunuchs?
Appointing relatives by marriage to high office?
Waging reckless wars?
Wrongfully executing loyal ministers and capable generals?
Great! Leave it to me!
But first, the office worker has to face a mourning period that has only just begun and still has twenty-six and a half months to go, along with the empress dowager and ministers who want to use it to strip her of power...
The main story is told in third person.
Possible trigger warnings:
1. A woman transmigrates into a man's body, then goes limp because her soul and hormonal system don't match.
2. There are children, born to the original body and his consorts before the heroine arrived.
3. The heroine has a low moral threshold.
4. This is a fictional world. The heroine comes from its modern era, which once had the same history (so historical idioms can be used), but the timeline gradually diverged later on.
Theme: May everyone in the world have a better life.
