Prison Doctor

Three years ago, he was angry with his girlfriend and hurt someone. He was imprisoned for intentionally hurting someone.
When I returned three years later, my family encountered changes. My elder brother and sister-in-law were killed in a car accident. My father was lame in one leg. My seven-year-old nephew contracted leukemia. The medical clinic passed down from my ancestors was gone.
In order to maintain the family income, my father borrowed money from usury and the family was completely devastated.
At this moment, his girlfriend betrayed him, and his ex-girlfriend gave him a cuckold.
That can only be a showdown. He is not a reform-through-labor prisoner, he is a prison doctor, and he is the prison emperor.
His name is Chen Pingan.
