The Demon Doctor's Clinic GL

Dugu Xin is a world-renowned cardiothoracic surgeon, medical doctor, professor at Haida Medical School, director of the cardiothoracic surgery department at Haida Medical School's First Hospital, director of its Heart Disease Center, and head of the heart and lung transplant team at its Key Laboratory of Multi-Organ Transplantation and Key Laboratory of Organ Transplantation.

But he has another identity: attending physician at the Demon Doctor Clinic.

Every night, a Demon Doctor Clinic opens in a remote little alley.

Demons, spirits, ghosts, and monsters may all seek treatment here, but they must pay an equivalent amount of demonic power in exchange.
