City: I Decide My Own Destiny as a Villain Through Time Travel

As a social youth in the 21st century, one day I traveled to the world of a novel. "But why would I travel to a villain? Why do I have to follow the plot when I get the golden finger? I won't follow the plot yet. You are my system's golden finger. Why don't you let me kill the protagonist? What? If you kill the protagonist, you will be discovered by heaven! Okay, okay, let's have fun! Then I can cripple him." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
