Cheng Tian was a top student in the Northern Qing Dynasty, but due to an accident, he exchanged souls with his ex-girlfriend Lin Wan after breaking up for three years. The once aloof school beauty has now become his "body", and he is forced to live in her luxurious but empty mansion. To make matters worse, Lin Wan's current boyfriend is actually a newbie in the business world, and he dotes on her in every possible way. Faced with the regret of his ex-girlfriend, the hostility of his current boyfriend, and the crisis of his identity being exposed, Cheng Tian relied on his super brain and hidden cheats - the "thinking accelerator" to crush his opponents in finance, technology, and academia, and made a comeback. When Lin Wan cried and begged him to change it back, Cheng Tian sneered: "Are you worthy?"
