The Most Ruthless Person in the Late Sui Dynasty: He Slaughtered the Entire Li and Tang Clan at the Beginning

Traveling through the troubled times of the late Sui Dynasty, I activated the "God-killing System" - the harder I killed, the more ferocious the rewards! At the beginning, I was surrounded and suppressed by Li Tang's army. I backhandedly slaughtered Taiyuan and slaughtered all the nine Li Yuan clans! Li Shimin knelt down and begged for mercy? Kill it with one sword! Li Xiuning wants to marry her to save her life? Send her down to meet her ancestors! "Ding! Slaughter the royal bloodline and reward one hundred thousand dead soldiers in black armor!" From now on in this world, whoever I want to die at the third watch, the King of Hell will not dare to stay at the fifth watch! Yang Guang is fatuous? Regicide to seize the throne! Wagang is powerful? Trap and kill one hundred thousand! Turks invade the border? Build the capital and see thousands of miles! The world calls me a "human massacre" and laughs at me as a "crazy devil", but they don't know that in this troubled world - kindness is the original sin, and ruthlessness is the king! "Your Majesty, the five surnames and Qi Wang have been wiped out, and no aristocratic family in the world dares to raise their head!" In this life, I want all the people the sun and moon shine on to be Han! Those who follow me will prosper, and those who go against me will kill the nine tribes! (Decisive in killing + tyrant style + fighting for world supremacy + no female protagonist)
