One day, a poor male college student suddenly had a black eye on his way home from work. He woke up again and found himself in a world of immortality! Or a well-known and upright senior brother! Just when he was at a loss, something called the "system" appeared in his mind and told him that the world he was in was a book. He told him to be careful and threw a bunch of things at him before disappearing. Having read all kinds of novels, I immediately understood this routine - I must be the villain cannon fodder who tortured the protagonist and wanted to save him! But here comes the question, who is the protagonist? How do I save the protagonist and clear my name smoothly?
Intention: Just take a look while walking by
