American Killer: Kill the Traitors of the Beggar Gang at the Beginning

My name is Matthew, and an accident caused me to travel to the parallel world of America. Bad news: Identity is a homeless man who fell off the kill line. Good news: I am bound to the [Xia Ke System], and you can get unique skills by "punishing evil and promoting good"! But wait, what does it mean that the streets are full of homeless people, beggars and traitors are rampant, the drug addicts on the roadside are the abominable Five Poisons cultists, and the muscle tyrants in the gym are the disciples of Yaowanggu? What does it mean that an underground killer organization uses force to break the law? Although flowers of evil are blooming everywhere in this land, this is a bit too crazy. No matter what, the world is full of demons and turmoil, how can we just sit idly by and watch? "All evil heretics, court eagles and dogs, please listen carefully. Hero Xiu Ma is here!"
