I've Become the Villainous Empress of a Novel

After a night of heavy drinking, I found myself transmigrated inside a novel as the villainous Empress Yulia, who will be executed for treason in three days. This is a project to find a way for the workaholic empress to live, exact her revenge, and prevent treason from happening. Will I be able to become a good and wise ruler? The constitution of an unexpected empress. The turbulent reign of the straightforward and gentle-looking, but iron-fisted Empress Yulia.
