One Murder Makes Me a Criminal; Slay a Million and I Become an Emperor for the Ages

[Decisive and ruthless + invincible + revenge + crushing all opposition] After transmigrating to the Great Qian Dynasty, Lin Yu studied hard for thirteen years and finally became the top scorer in the imperial examinations. The empress took a liking to him and personally chose him to be the princess's consort. At a palace banquet, Lin Yu struck back and killed a neighboring kingdom's crown prince for harassing the princess. The emperor, however, exiled him to the enemy state as a slave, while corrupt officials slaughtered his village and wiped out its people.

He personally led an army of ten million to surround the Great Qian capital. The Great Qian ministers joined forces with the empress to hang the old emperor, all in a desperate bid to beg Lin Yu for mercy. The Great Qian Empress: “The emperor is dead. I am now the Great Qian Empress in my own right. I will marry the princess to you today. I only ask that you spare the people and soldiers of Great Qian!” Lin Yu: “I'm taking the princess, and I'm slaughtering Great Qian's million soldiers and civilians too. And you, Great Qian's empress, I never planned to spare you either...”
