In the modern era, a young boy named Luo Zhongxia stumbles upon a mystical pen spirit deeply linked to the 'Seven Marquises of Guancheng.' This encounter unlocks the door to a marvelous world related to the 'Pen Tomb' for him. Yet, as the boy experiences this extraordinary adventure, he becomes a target of various factions due to the value of the pen. Desiring to avoid these conflicts, he is dedicated to finding a way to relinquish the pen. Though his attempts to do so often go against his wishes, these trials foster his growth. He evolves from a student known for fleeing and ignorance into a responsible, tactful 'Officer of the Pen Tomb.'
