I'm a Bad Student

Is history really as written in the books? I - Qin Chuan, a scumbag in everyone's eyes, I hate history classes the most, but I traveled through time because of an accident. Living on the street, penniless, relying on only modern knowledge, he became a top student in the ancient world, making counterattacks all the way. History is written by successful people. I, Qin Chuan, want to write a piece of my own history, so that when history teachers teach this period of history thousands of years later, they will tell their students that this person's famous saying is - "I am a scumbag". This is a must-test question, and everyone must recite it.
