Medical America: I Relied on the Devil to Get Through the Killing Line

Lynn has been reborn in America, but with the timeline too advanced for early crypto investments, he settles into his profession as a doctor—until he stumbles upon an illegal human organ trafficking ring and finds his life on the line. [New demon detected: Succubus]. Dismissing the system's warning at first sight of an angelic blonde American sweetheart, Lynn soon learns the harsh truth: Hell is empty, and the demons are in America. Fortunately, his Demon Identification System allows him to calculate related world lines and reap rewards, helping him survive the demonic underbelly of New York. By day, he is a law-abiding Chinese-American physician; by night, he is the terrifying Black Jack, armed with skills ranging from advanced firearm mastery to master-level blunt dissection.
