Zhong Qingxue, a top competition master, was reborn as a "scumbag" in the ordinary class of Xinglan Middle School. Due to an accident in her previous life, she was determined to hide her strength and live a stable life. However, the bullying and contempt in the elite class continued to escalate, and class monitor Ling Wei publicly mocked her many times for "holding the class back." In a city-wide joint examination, Zhong Qingxue was forced to submit a perfect answer sheet to protect her classmate who was falsely accused of cheating, which instantly detonated the campus. When she successively exposed her multiple identities such as Mathematical Olympiad gold medal winner and paper publisher, those who once despised her were slapped in the face. Even the cool school boss Cheye changed from a doubter to her ally. In the end, the whole school witnessed the "scumbag" counterattack and turned into a real academic boss.
