Great Qin: From the Start, I Snatch Jing Ke and Build an Invincible Army

After transmigrating into Great Qin, I become the secret bodyguard of the eldest prince, Fusu. Just as I'm preparing to assist this benevolent prince, a mechanical voice rings in my head:

[Ding! Villain Roleplaying System successfully bound!]

[Newbie Mission: In front of Ying Zheng, kill the assassin Jing Ke with a single sword strike before Fusu can, then say: "Your Majesty, benevolence and righteousness cannot save Great Qin!"]

[Mission rewards: Max-level Sword Grandmaster cultivation, control of the Black Ice Platform, and +50% trust from Ying Zheng!]

Seeing Fusu's shocked expression, I smile. Sorry, Eldest Prince. Your virtue, your empire, and your woman: I want them all!
