A Killer and The Heroic System

Guan Yu, a mass murderer, killing over hundreds of people over the past decade. But the most shocking thing of all, he was only 11 when he killed his first victim, his abusive step-father. Unfortunately, he did not just stop there. For ten years, the police were never able to capture him for at least once Until today. After a swift chop to his neck with a large silver ax, he was transported to a cultivation world with a system. But not just any system, The Heroic System! The moment he saw the functions of the system, he cursed the heavens for giving him this system. "Thank you, Guan Yu, for saving me from those bandits!" "I give you my gratitude for rescuing me from those filthy men." "Sir Guan Yu! Let me give you my thanks for saving me from the legions of the undead king!" "I have nothing to offer you, Sir Guan Yu, except this simple thanks of mine for giving me this wealth to live a new life again." Guan Yu sighed as he looks at his back, only to see thousands of people giving him their gratitude. "At least, I still get to kill people. Sigh, what a life."
