Metropolis: I Started with a Watermelon Knife and I Went Crazy.

Yang Tian traveled to the chaotic urban world, activated the system, and collected protection fees to become stronger. On the first day of the fight, he beheaded people on the street and killed several people in a row. Afterwards, he even came to threaten the victim's family members to change their confessions, and the murderer suddenly became a good citizen. In this world, as long as you are ruthless and strong enough, you can do whatever you want. Robbery of projects, mines, and women is commonplace. Even if people from the Imperial City inspection team come, Yang Tian will still kill them without fail... This novel and its characters are purely fictitious.
