Sorry, I Can't Beat Anyone, but I Can Instantly Kill Supreme Experts

[Fantasy + System + Wild Imagination + Face-Slapping + Misunderstandings + Lighthearted Comedy] While getting intimate with his girlfriend, Lin Feng is struck by lightning and accidentally transmigrates to Qingyun Sect, where he becomes its sect master. But he has not an ounce of cultivation and is a complete weakling. To keep up appearances, he even shuts himself away in confinement for ten whole years. At last, one day, the System he has been longing for finally arrives. Only, this System seems a little bizarre. “System, are you saying I can kill a Supreme in an instant?” “That's right.” “Then why can't I even beat some random nobody?” “I said you can only kill Supremes instantly. You can't beat anyone else.” “What kind of scam is this? How am I supposed to play like this?” … And so, with a gloomy look on his face, Lin Feng can only sharpen his blades and go after the Supremes. If I wipe out every Supreme, no one should dare come looking for trouble, right? The Supremes cry out in alarm: “Boss, please spare us!”
