Haunted House Transaction, Zero Negative Reviews

"Every house that has passed away has an unfulfilled contract." Under the reinforced concrete of modern cities, there exists a hidden gray market - the transaction of haunted houses. Former criminal police officer Lu Chen partners with Gu Qingming, a descendant of a family of traditional Chinese medicine who can "see spirits", to run "Pure Land Real Estate", specializing in purchasing haunted houses that are 70% lower than the market price, and then resell them to make a profit after getting rid of "grievances". However, when they were cleaning up the seventh haunted house, they found that all the cases pointed to the same mysterious symbol-"The Deed of Immortality".
