I actually came across 'Emperor' after reading a lot of historical web novels, and the main plot initially follows a fairly classic rise-from-humility arc. The protagonist starts as someone with little power or status, navigating a brutal court or empire filled with political schemes. The central drive is his ascent to the throne, overcoming aristocratic factions, rival princes, and sometimes even supernatural threats depending on the specific version. It's less about grand battles and more about the intricate, often ruthless political maneuvering—who to trust, when to strike, how to manage public perception.
Honestly, a big part of the appeal for me was the protagonist's internal struggle. He's often portrayed as someone who has to sacrifice his own morality or relationships to secure power, which creates a constant tension. Is becoming the emperor worth losing his humanity? That question hangs over a lot of the later chapters. The key characters are usually his small circle of loyal advisors, a love interest who might be from a rival family, a scheming eunuch or chancellor figure, and of course, the sickly or paranoid current emperor. I remember one version where the main character's most trusted general betrayed him in the third volume—totally gutted me, I didn't see it coming at all.
