I Am Such a Villain!

[Fantasy + Villain + System + Time Travel] This world is full of weirdness, there are immortals, gods, monsters, demons... However, this world is inherently false. And I, an ordinary person named Lin Ran, accidentally broke into this world by chance. What made me even more unexpected was that I actually awakened the legendary golden finger system. This is exactly the treatment that only the protagonist will receive. But fate played a trick. I was set up in this world to be a villain, but fortunately I still had the Golden Finger System to rely on. In this world, I also learned the identity of the Son of Destiny, who turned out to be my junior brother who has always been harmless to humans and animals. Now that things have reached this point, I'm sorry, junior brother, but don't worry, senior brother, I will try to make you suffer as little pain as possible. I will be very gentle and will only kill you with one move.
