Liu Bian at the start, so you're called Dong Zhuo, right?

Transmigrated into the body of Liu Bian, he faced an oral examination and registration by the Ten Attendants on his very first day returning to the imperial palace. Liu Bian understood clearly that surviving within these walls required him to become a consummate actor. Rather than rushing to seize power, he focused first on securing the cornerstone of the realm—building his legitimacy, earning the devotion of the people, and enlisting capable talents. Only after cementing his position as crown prince would he begin recruiting the future scholars and generals of the Three Kingdoms into his service. Yet the true crisis brewed far beyond the halls of Deyang Palace, out in Liangzhou. There, commanding the formidable Xiliang iron cavalry, a warlord named Dong Zhuo was steadily marching his military might toward the capital of Luoyang. When Dong Zhuo’s army finally arrived outside the city walls, he was met not with the sight of a terrified young emperor, but with a calm, piercing question: "So, your name is Dong Zhuo, is that it?"
