Chen Changsheng, a young man whose name sounds like a joke, inherited a Feng Shui antique shop "San Bu Kan Tang" left by his grandfather that was on the verge of bankruptcy. In order to repay his debts and make a living, he had to return to his ancestral business and use the Feng Shui magic technique he had learned half a bucket of water to solve various "difficult diseases" for customers in the city.
A huge commission from a mysterious beauty involved him in a strange and haunted house. He soon discovered that this was not a simple haunting, but involved a vicious Feng Shui scheme that used human lives as sacrifices - the "Seven Kills and Raise Evil Scheme". As the investigation deepens, competitors, shady businessmen, and ancient families who have inherited evil arts have emerged one by one.
Chen Changsheng relied on his ancestral dragon-seeking and acupuncture skills and his "half-bottled" cleverness to travel between the yin and yang realms, shuttling between the reinforced concrete of the city and the ancient secrets of Feng Shui. What he has to do is not only to make money and keep his grandfather's shop, but also to find a way out for himself and the innocent victims in this treacherous whirlpool. This is a suspenseful adventure story about a little person using the wisdom of his ancestors to struggle, survive, and uncover the truth in a modern city.
