Crazy Doctor: I Treat the Old Gods as Patients

I always thought I was just sick. Until I saw eyes sprouting from the back of the professor's neck, the food in the cafeteria began to rot into lime, breathing ruins were buried under the campus, and all abnormalities would be quietly repaired by the world the next day, as if they had never happened. So I decided to treat them. Cut open the monster, clean the lesions, record the symptoms, and continue taking the medicine. But the more I treated him, the more reality collapsed; the closer I got to the truth, the more I discovered that those monsters knew me. And I am the most dangerous disease in this world. When the old gods begin to use medicine to explain the indescribable, the first one to be cut open is often himself.
