The following two novels meet your requirements: 1. " Carry the League of Legends System with You ": This is a fantasy novel about an alternate world. The protagonist has the League of Legends system, which allows him to show off his infinite glory in the alternate world. 2. " Rebirth: Destroying the System ": This is a novel about urban life. The protagonist traveled to high school ten years ago and became another person in a parallel world. In the process of becoming an elite of society, he was dominated by the system. Rebirth was just a game, and the protagonist had to destroy the system in the end. I hope my recommendation will be helpful to you.
