In an age of spiritual qi revival, supernatural incidents are happening all over the city. Qin Yu simply summons a clone and becomes an agent of justice, gleefully harvesting the kidneys of monsters.
Kobold: “Are you the Night Watch? I want to report a crime. Someone’s harvesting my kidney. That’s right, he’s doing it while I’m alive, and he didn’t even use anesthetic.”
Cat Demon: “Qin Yu is a monster! He could have had a beautiful fairy like me, but instead he went and took my kidney!”
Some Black Mountain Demon King: “I can hardly believe humans can be this shameless. He even summoned a clone to help rip out my kidney. I hope I never run into Qin Yu again in my next life.”
...Faced with the monsters’ tearful complaints, Qin Yu shrugs. “They’re slandering me, slandering me! I’ve never harvested their kidneys. I’m just the kidney delivery guy.”
