Zhang Zhihe (Zhang San) originally just wanted to be a casual Feng Shui master - helping people adjust their homes, doing rituals occasionally, and earning a little money to make ends meet.
But who would have thought that just because he helped the old man pray to the Supreme Lord for longevity three times, he was directly brought to him by the King of Hell: "You have overstepped your authority to interfere with Yin and Yang matters, and I will punish you as a part-time errand for one year, investigating cases of abnormal life and death!"
From then on, Zhang San's life was completely messed up: during the day, he had to help customers with the Feng Shui evil-eliminating array, and at night, he had to follow the rigid old Zhou and the lively Xiao Lin to investigate "murder cases that should not die" - it might be the "soul-falling array" set up by his competitors, or it might be the "Qi-eating Bureau" caused by family grievances.
What made him even more entangled was the olive branch offered by the King of Hell when his part-time job expired: "If you become a full-time employee and stay in office, you will be given 1,000 merit points for each case. If you save 100,000 points, you will directly become a judge at the end of your life. Your father is working as a temporary clerk in the underworld? Converting to a formal establishment is a matter of one sentence."
On the one hand, there is the freedom of being a casual cultivator, on the other hand, there is the responsibility of the underworld and the stability of his family, as well as those who are waiting for him to break the situation and save lives... Zhang San finally chose to stay.
What's even more surprising is that Taishang Laojun personally descended to earth, gave his sect the "Qing Sect", and allowed him to open the door to accept disciples. The King of Hell also expressed his support and hoped that he would cultivate Yin Cha's successor. Three disciples with very different personalities (Lin Xiaoman, Zhao Lei, Xiao An) became apprentices...
From personal practice to sect inheritance, from Feng Shui in the Yang world to order in the underworld, Zhang San proved in his own way: Feng Shui saves people but does not harm others, and both Yin and Yang worlds need to be upright.
