In the apocalyptic wasteland, demons are rampant and Confucianism and Taoism are in decline. The handsome scholar {Lu Chen} possesses the golden finger of the "Sacred Heart of Confucianism and Taoism". He appears to be carefree, but in fact he can quell evil with pen and ink and slay demons with poetry. However, he deliberately hides his clumsiness to avoid disaster. By chance, he rescued the innocent and ignorant girl Su Xiao, and accidentally got involved in the dispute between the real and fake daughter - Su Rou, the real daughter of the Su family, returned in black form, colluded with evil demons, wanted to seize the Su family's power, and even coveted Lu Chen's Confucianism and Taoism power. While Lu Chen was protecting Su Xiao from being chased, he was forced to show off his strength and use counter-tactics to slap the villain in the face: admonishing the rebellious little demon with the "Encouragement to Study" chapter, repelling the thousand-year-old demon with the "Song of Righteousness", and even exposing Su Rou's hypocritical mask. When the darkness of the wasteland approaches, Lu Chen will finally use the light of Confucianism and Taoism to carve a way out.
