At the end of the Qing Dynasty and the beginning of the Republic of China, the country changed its banner and yin and yang were out of balance. The Lin family in Jiangnan was destroyed by zombies overnight, but young Lin Jiusheng managed to escape. In order to find out the truth, he went to the mountains and became a disciple of Xuan Chenzi, a retired heavenly master in Longhu Mountain, where he practiced the secrets of Maoshan Feng Shui and Qimen Dunjia.
After five years of study, Lin Jiusheng came down from the mountain to join the world, only to find that evil spirits were rampant in the land of China: corpses mutated frequently on the road to drive corpses in western Hunan, Southeast Asian merchant ships brought back strange heads, grassland shamans summoned ancient evil gods, Miao Gu masters cultivated bloodthirsty poisonous insects... Behind every strange incident, it seemed that there was a vague reference to the mysterious man wearing a ghost mask on the night when the Lin family was exterminated.
From the water towns in the south of the Yangtze River to the grasslands of Mobei, from the mountains of western Hunan to the islands of Nanyang, Lin Jiusheng relied on orthodox Maoshan Taoism to determine the universe with Feng Shui, lock Yin and Yang with strange doors, and suppress evil spirits with spells. He fights zombies, breaks witchcraft, frees heads, fights shamans, and comprehends the true meaning of Taoism on the edge of life and death again and again. As the investigation deepens, a shocking conspiracy that spans thousands of years gradually comes to light - someone is trying to gather all the magic in the world, reverse the yin and yang, and open the legendary "Gate to the Netherworld."
When the four evil factions join forces to besiege the city, when forbidden magic reappears in the world, and when close friends are forced to stand on the opposite side, Lin Jiusheng must make a choice: should he strictly adhere to the right path and proceed step by step, or risk using forbidden magic to fight violence with violence? In the end, he realized his own "Tao" - the real Maoshan technique, which is not about crushing evil spirits, but about resolving cause and effect and balancing yin and yang.
This is the ultimate showdown between traditional Taoism and evil ways. It is also a path of growth for a young heavenly master to find the right way, inherit and innovate in troubled times.
