A good, law-abiding young man in the 21st century thought he was about to embrace a bright future full of freedom after the college entrance examination, but he was severely hit by a falling object while walking... When he opened his eyes again, he was greeted by a new world of swords and magic. The elements are mixed, here are some points that need attention: 1. No cp. 2. The protagonist travels through time. 3. It's not a cool novel, the protagonist is not that smart. 4. The character names are all made up, and there is no such language in reality.
