After the Qing dynasty’s defeat in the First Sino-Japanese War, its fortunes declined, sinister spirits ran rampant across the land, and dark sects flourished. Shen Yan transmigrates into the body of a young Daoist novice at Qingwei Temple on Mount Qingyang.
Blessed with the Profound Observation Mirror, he can distinguish good from evil, complete cultivation methods, and expose eerie mysteries. Shadow-puppet demons in the villages, official spirits in the city, and foreign sorcery overseas all wreak havoc, leaving the people in misery.
The imperial court is corrupt, occult arts are in disarray, and the righteous path is in decline. Shen Yan braves danger and descends the mountain to solve one bizarre case after another, accumulating merit and restoring the Qingwei tradition. In an apocalyptic age when the great edifice is on the verge of collapse, he uses the remnants of his own Dao to preserve one last glimmer of clarity in the human world.
