The genius writer Shen Mo accidentally traveled to the Yongzheng Dynasty and possessed a poor and frustrated scholar. He discovered that there was an undercurrent in this world: the alien race had already transformed and lurked among humans, controlling underground auction houses, buying and selling human organs and secrets, and even colluding with dignitaries in the DPRK and China to subvert the country. Shen Mo awakens the 'Zhu Yibi' system - every word he writes can be turned into a real attack, and all poems and songs can kill demons. In order to obtain information, he disguised himself as a down-and-out scholar and sneaked into an alien auction house. He witnessed the aliens auctioning human cubs with his own eyes. He was so angry that he swung a brush on the spot and shattered the auction table with his song "Ode to Kill Monsters", killing several alien masters. This incident alarmed Emperor Yongzheng, who visited privately in Weibo. Yongzheng secretly summoned Shen Mo, appointed him as a secret agent, and established the "Bi Feng Division". Shen Mo uses writing as a sword, from exposing the shady secrets of the auction house to dismantling the alien intelligence network, and gradually becoming the most feared person by the alien race. On the surface, he concealed his evil intentions, secretly plotted, and used words to uproot the alien forces step by step. In the end, in the double showdown in the court and on the battlefield, he wrote a new chapter for the human race and protected the peace of the dynasty.
