You Are a Young and Dangerous Boy, Collecting Protection Fees and Issuing Invoices?

My name is Xue Rang, a time traveler and a young and Dangerous boy. Good news: I retain all the knowledge of a top lawyer from my past life. Bad news: He's 199cm tall, has scars all over his face, and looks like a peerless gangster. My eldest brother asked me to collect protection money. I took out the "Legal Consultant Contract" with my backhand, and my boss signed it with tears in his eyes. The eldest brother nodded with satisfaction: "Yes, Arang, the deterrent force is strong enough to defeat others without fighting!" Big brother asked me to negotiate. I pointed out 27 loopholes in the other party's contract on the spot, and the other party paid three times the liquidated damages. The eldest brother excitedly patted me on the shoulder: "Good boy, you can make the other party pay money with just a few words. You are born to do this!" My elder brother asked me to "educate" a domestic violence man. I helped his wife get a divorce, let him clean up and leave the house, and I also paid huge compensation. The eldest brother looked at the neighbors who were crying and sending banners, and was filled with emotion: "High! It's really high! It hurts people's hearts. Arang has mastered the art of intimidation!" Me: "..." No, brother, please listen to my explanation! I'm really just a good, law-abiding citizen! Big brother (handing over an AK): "Don't be humble, you will be the leader! Lead the brothers to make the club bigger and stronger!"
