Danny from a Police Family

A modern policeman suddenly travels across the interstellar space and comes to the variety movie world transformed from a TV series he followed before, and becomes the protagonist Danny. His family is a police family in this city, and most of his family members work in law enforcement agencies. My grandfather is the former police chief, my father is the current police chief, I am a first-class police detective, my sister is a prosecutor, and my second brother is also a police officer. He was shot dead for disobeying a rogue police officer in the police station. The third brother graduated from a prestigious school, but joined the police force in order to avenge his second brother. Danny has an intelligence support system and room for growth, but it's a pity that he doesn't know how to use it. This is the first time I want to write a work. I welcome your criticisms and corrections. Thank you.
