Three Kingdoms: Villain Liu Bei Starts by Killing Guan Yu and Slaughtering Zhang Fei

[Villain protagonist + decisive and ruthless + no romance + satisfying power fantasy + alternate history]

Dong Zhuo: "Want to see if my sword is sharp?"

Liu Bei: "Let's see if your blade is faster than my spear."

Yuan Shao: "My spear's no slouch either."

A high school student transmigrates as Uncle Liu, Liu Bei. Looking at the space packed full of supplies and weapons, he brings an arsenal of modern weapons to the ancient Three Kingdoms era and crushes everyone with overwhelming technological superiority. Arrogant and quick to kill, he has a violent temper. He later reunifies the Han by force and seizes power over the empire, but spends his days indulging in the beauty of his harem and neglecting state affairs, eventually becoming the retired emperor. He punches Yuan Shao, heir to four generations of high ministers, and kicks Cao Mengde aside. Later, he points a gun at Zhang Jiao and triggers the Yellow Turban Rebellion. To his surprise, Zhang Jiao is a transmigrator who graduated from a top university, setting up a showdown between two transmigrators in the late Eastern Han dynasty: a high school student and a top-university graduate. To win the war, Liu Bei decides to establish a modernized army. That decision puts guns in the hands of ordinary people and threatens his rule, forcing him to change his ways and win people over through virtue. As Liu Bei's fortunes begin to decline, he finds himself on the back foot in court at every turn. Yuan Shao even points a gun at him and says, "My spear's no slouch either."
