Qingxuan Town: Yin and Yang

Three knocks at midnight—if not human, then ghost. On the night of weeping at a deserted village grave, the living must not answer. Shen Yan, an ordinary disciple of the Qingxuan Daoist Academy, of middling talent, with no destined fate, no bloodline, no system. What he knows are the rules—peach wood to suppress evil, glutinous rice to dispel yin, rituals to ferry the dead; talismans consume vital blood, spells depend on timing, none can be omitted. Ghostly calamities all originate from humans. A century ago, a renegade genius who left the orthodox path founded the Yinyang Evil Sect, specializing in twisting taboos and inducing human malice to devour yin and yang. After the great righteous-evil war, orthodoxy withered, while the evil sect secretly wove a vast web. Fortunately, he meets Su Qingyuan, a female Daoist of Lingxiao Temple—cold and resolute, with orthodox methods. The two go from conflicting ideals to trusting each other with their lives, with no love triangles, only like-minded comrades. Those who can be saved, save; those who deserve death, kill. With solid fundamentals and a pure, righteous heart, Shen Yan, alongside his comrades, cleanses the evil sect and rectifies yin and yang. This is the righteous path.
