In the last years of the Dajing Dynasty, the literary arts were in decline and the martial arts were rampant. The Immortal Sect was aloof and regarded ordinary people as stupid dogs. In Qingzhou City, Qingzhou, Ling Yunxiao, a scholar from a poor family, lost his parents when he was young. He was adopted by an old scholar from a dilapidated temple in the south of the city. He made a living by copying books every day. An old pen in his hand was his only thought. Who would have thought that this seemingly ordinary writing brush was actually a "world-shaking brush" left by an ancient literary sage, containing the inheritance of literature and Taoism. In order to protect him, the old scholar died tragically at the hands of a martial arts monk. Before his death, he warned him: "The pen can carry the Tao and control the law; literature can stabilize the country and can stabilize the sky. In this troubled world, a pen is needed to bring order to the chaos." With hatred and entrustment, Ling Yunxiao embarked on the journey. He entered Taoism with writing and used his pen as a soldier. Writing the word "loyalty" can gather great righteousness, drawing the shape of "shield" can block thousands of troops, and writing the word "reason" can set the rules of the world. Along the way, he met Ye Qinghan, a rebellious swordsman girl, Su Muyan, a medical successor who cared about the common people, and Mo Chenyuan, a young demon master with a swaying attitude, and started dealing with martial arts sects, decayed fairy sects, and ancient demon courts. He discovered that the decline of Wen Dao was not accidental, but the legacy of the ancient "War of Divine Wen Dao". In order to compete for the destiny of the world, the immortal sect and martial arts joined forces to suppress Wen Dao. As a mortal, Ling Yunxiao traveled thousands of miles, read thousands of books, and understood the way of the world. In the end, he not only wanted to rectify the name of literature and art, but also reconstructed the rules of the world - let immortals, martial arts, literature, and mortals all have their own places, let reason prevail over power, and use a pen to settle the broken rivers and mountains, and bring peace to all living beings.
