Dong Yan, who came through his soul, was born in a world with declining culture and Taoism, carrying the inheritance of a full-level Confucian sage. In Qingshi Town, he intimidated the rogue gangsters with his holy words of "rituals cannot be abolished", exposed Zhang Shijie's cheating with his literary self-promotion in the examination room, and recited "Song of Righteousness" in the suburbs to purify evil beasts. In this world, a sect was established to recruit disciples, spread its method of "studying things to gain knowledge", use Confucianism to organize the new world structure, single-handedly block the evil spirits, and finally integrate the sect's power to fight against the evil catastrophe that will destroy the world.
