The grandfather of Chen Jinan, an ordinary college student, who depends on each other for life, suddenly disappeared, leaving only a strange "Gu" hexagram and a "no return" warning. A notebook and an old photo led him to Gu Linyuan, a top rich man who was famous in the provincial capital, and also tore away the pretense of his ordinary life.
Grandpa is not an ordinary Feng Shui master, but a reclusive master from Wudang Mountain, the holy land of Taoism. His disappearance is closely related to a shocking old case that has been silent for seventy or eighty years and is about pursuing the secret of "immortality". Only then did Chen Jinan realize that his special fate of "Pure Yang" had already made him the focus of countless greedy eyes in the darkness.
In order to find his loved ones and save himself, Chen Jinan had to step into a strange and mysterious world. Taoist Taoism, folk occult arts, mysterious institutions, evil organizations... All forces are on the stage. He must use half of the "Burial Book" left by his grandfather and his physiognomy and feng shui skills to get rid of the cocoon between the neon lights of the city and ancient legends.
However, as the investigation deepens, a more terrifying truth emerges: the biggest secret guarded by grandpa is actually closely related to his own confusing life experience. This thousand-year mystery surrounding "immortality" is waiting for him to reveal the final answer.
