Two millennia ago, a descendant of the Yinyang Family grieved over the burning of books and the burying of scholars ordered by Qin Shihuang, the first emperor of the Qin Dynasty, as well as the destruction of the Epang Palace. Determined not to let the scholars die in vain, he began transforming their spirits into brushes for future generations to inherit. In the present day, Luo Zhongxia, an ordinary college student, accidentally acquires a brush containing the spirit of Li Bai, thereby gaining its superpower. However, before long, various forces engage in a frantic scramble for this power, placing Luo Zhongxia in danger on numerous occasions. To avoid further peril, Luo Zhongxia attempts to find a way to return the brush, but fails each time. Instead, Luo Zhongxia becomes inextricably bound to seven brush spirits.
