When I'm on the night shift, all the department heads can't sleep.

Lin Ye was just an ordinary resident at the First Municipal Hospital. No one listened when he made rounds during the day, and no one believed him when he saw patients on night shifts.
Until his first night shift alone, a notification popped up in front of him:
[Common stomach pain? 97% risk of aortic dissection.]
[Death countdown: 42 minutes.]
His superiors told him to stop making trouble, the nurses advised him not to take responsibility, and the patient's family scolded him for making a mountain out of a molehill.
Lin Ye's phone call woke up the head of the cardiac surgery department.
From that night onwards, a saying circulated in the First Municipal Hospital:
You may not know Lin Ye during the day, but never turn off your phone at night.
Because whenever he works the night shift, none of the hospital directors can sleep.
