There's Something Wrong with This Medical Clinic

A strange resurgence occurs, and demons inhabit the city. Lin An inherited a pet hospital that was on the verge of bankruptcy. Not only could it not pay the rent, but evil forces came to collect debts. In times of despair, the Demon Illustration System awakens. As long as the demon is cured or dissected, the core magical powers and pure blood can be extracted! As a result, the style of painting began to change. The superior thousand-year-old fox demon obediently queued up to register and beg him to see a doctor; the world-destroying ferocious beast that was causing trouble was tied to the operating table and shivering. "Dr. Lin, can my headache be cured?" A certain headless ghost king asked cautiously. Lin An pushed up his gold-rimmed glasses and picked up the boning knife: "It can be cured, just change the head. The family will pay the fee first." When the urban restricted area was completely out of control, thousands of demons descended, and everyone fell into despair, they found those arrogant demon kings kneeling in front of a pet hospital, shouting "Welcome the director to visit"...
