A Taoist temple that is popular among the neighbors. The host inside is not only a Taoist master, but also a philosophical wise man - Peng Baichuan. By chance, he met three young men, Zhang Hanzhong, Xu Boqiang, and Sima Zhiquan, and became his apprentices. The four masters and apprentices solved the problem of neighborhood hauntings and gradually became famous. One day, the Seventh Action Team of the police invited Peng Baichuan to help. With Taoist wisdom and magic, the four of them solved the cases one after another, and were gradually recognized as the consultants of the Seventh Action Team, becoming the first generation of "spies"! The story is set in Hong Kong in the 1980s, and involves traditional Chinese folk superstitions and customs, such as the Bon Festival, ghost marriage, becoming an immortal in five hells, etc. The subject matter is full of mystery.
