Chen Jiujin is a descendant of a family that drives corpses in western Hunan. He learned Feng Shui and Yin and Yang from his grandfather since he was a child. However, when he ordered a ghost house for a neighboring village, he missed the taboo on the "corpse place", causing his grandfather to protect his soul and return to the underworld. He only left behind a incomplete "Yin and Yang Record of Walking Mountains" and the advice "Don't go to the Yin and Yang when you are in the mountains, and don't explore the bottom when you encounter water." Eighteen-year-old Chen Jiujin carried his grandfather's peach wood compass and yellow preacher's robe on his back, and embarked on the road of "paying off his wishes and eliminating karma" for his grandfather - traveling all over the country to resolve the nine bad Feng Shui problems left by his grandfather's soft heart during his lifetime. He walked from the Miao village in western Hunan to the ancient forests of the Qinling Mountains, and from the Gobi tombs in the northwest to the coastal fishing villages in the southeast. Along the way, he encountered all kinds of mountain and wild spirits: the "Tree Grandma" entrenched in the old locust tree, The "Water Monkeys" guarding the sunken ship, and the "Yin Soldiers" hiding in the ancient tombs; also got to know strangers from all walks of life: the Northeast Horse Fairy who knows how to "call souls", the Jinmen papermaker who can "tie paper figures", and Mr. Jiangnan Shui who can "cross the water". Every time he solved a bad Feng Shui situation, Chen Jiujin would find an extra page of comments in the notes left by his grandfather. These comments gradually connected a secret that spanned a century: Grandpa was not just soft-hearted, but discovered that someone was deliberately setting up the "Nine Locks Gathering Yin Formation", hoping to use the sinister energy of the mountains and mountains to awaken a sealed ancient evil. Chen Jiujin dealt with the weird stories and weird things along the way, while dealing with the evil sorcerers behind the scenes. Finally, at the "junction of yin and yang" in the Kunlun Mountains, he broke the Yin Gathering Formation with the final secret technique of "The Record of Yin and Yang in Walking Mountains", and finally understood the true meaning of his grandfather's words.
