Detective Di Renjie: Luoshui Surrounds the Capital

In Chang'an West Market, for seven consecutive days, on the night of the full moon on the 15th of each month, a wealthy businessman will turn into a charred corpse at home. The body's surface was intact, but its internal organs seemed to have been burned away by fire, with a strange fragrance remaining in the ashes. Dali Temple searched for three months and found no clue. Rumor has it that a demon monk from the Western Regions cast a spell and borrowed a human body to refine the soul and prolong life. For a time, Chang'an merchants closed their doors and the night market was depressed. Di Renjie was summoned into the palace by a secret order from the Queen Mother. "Di Qing, I only give you seven days." Di Renjie resigned, and as soon as he left the palace gate, he led Li Yuanfang straight to the widow's house. He did not look at the corpse, but asked someone to pass the scent to his nose, and closed his eyes for a long time. "This is not incense." Di Renjie opened his eyes, "It is oil. Western hemp oil burns when exposed to body temperature, burning the heart but not the skin."
