Modern/Republic of China: A young man in the city comes from a family with a decline in metaphysics. He learns the ancestral six-yao line, and uses small hexagrams to resolve trivial matters in the market. He meets a Feng Shui evil master for the first time, and is involved in a murderous case in a private ghost house. He uses the six-yao line to break the situation, gets acquainted with the descendants of a strange family, and uncovers the secret of the lost family tradition. With metaphysics as the core driving force, the plot revolves around deduction, solving puzzles, looking for dragons, acupoints, and determining the universe, restoring the core of Taoism "the unity of heaven and man, the Tao follows nature, and the balance of yin and yang".
