In the seventeenth year of the Republic of China, Lu Qingxuan, a disciple of Qingxu Temple in Zhongnan Mountain, was ordered by his master to go down the mountain with the mission of searching for the lost ancient book "Xuan Yin Lu", and also with the original intention of protecting the people in troubled times. Wearing a green preacher's robe, a mahogany sword on his waist, and carrying the heavenly compass, the treasure of the town, he stepped into the world of mortals.
From the "Chuangxinsha" Feng Shui bureau in a mountain town, to the salvation of resentful ghosts in Jiangcheng's deserted cemetery, to the bloody soul curse bureau in an ancient house in the northern suburbs, and the thousand-year-old zombie guardianship of King Zhao's tomb in Qinglong Mountain, Lu Qingxuan relies on his superb Xuanmen secrets to eliminate demons and investigate and solve the bureau. In troubled times, people are unpredictable and evil spirits are at work. Not only does he have to face the demons who practice evil arts and the mysterious messengers of the netherworld, but he also has to stick to the true heart of Taoism in the midst of intrigues and wars.
The work is based on the situation of the Republic of China, interweaving Feng Shui metaphysics, supernatural things and the feelings of family and country. In the eerie atmosphere, it composes a legendary journey of Taoist disciples breaking through the darkness with a green edge and protecting the common people with the right way.
