Black spark

Dai Lin became a surgeon at a strange hospital.
Here, they don't treat diseases but various horrific and mysterious curses! Divided into the Resentful Spirit Department, Malicious Ghost Department, Evil Ghost Department, Fierce Spirit Department, and the enigmatic Demons Department...
The eerie hospital, however, had some bewildering rules:
First, believe that the hospital is called Hospital 444, not 666 Hospital.
Second, between midnight and four in the morning, doctors and nurses must never enter the outpatient area.
Third, if you experience a severe headache and notice an inverted cross on your forehead, immediately seek treatment at the hospital's Demons Department.
Fourth, all doctors in the hospital wear white masks. If you see a doctor with a red mask, ignore them and make sure they do not realize you can see them.
Fifth...
And Dai Lin obtained a magical artifact, a pair of the Devil's Eye —the left eye could detect, sense, and attack, while the right eye could imprison, seal, and even devour and absorb.
And the source of all the terror in this hospital was the director who had never been seen by anyone...

Hospital 444

An elderly man woke up and stretched lazily.


"Is it almost noon already? I can't believe I slept for so long."


He sat up and started getting dressed. Once dressed, he put on his slippers, looked towards the window, and prepared to draw back the curtains.


His curtains needed to be pulled back using a cord, a specific design choice he had made during renovation to ensure they wouldn't be drawn back by simply a blow of the wind.


The old man's legs were not as nimble as they once were, his movements shaky as he approached the window. He then grasped the cord and gently began to raise the curtain.


He stopped, walked over to pick up the phone, and saw it was a text message from his son.


"Dad, quickly pull back the curtains and have a look."


The old man returned to the window with a suspicious look and completely drew back the curtains...


The very next second, shock registered on the man's face...
