Being an undercover cop is very difficult.
Luo Xin resolutely broke into the Jiu Ming gang, not only for the sake of the people, but also to find an undercover policeman who entered Jiu Ming five years ago.
There is no news about him, and his life or death is uncertain.
But Luo Xin didn't believe it.
He had been waiting for him for a long time. Others said he might be dead, but if Luo Xin couldn't find him, he would keep searching for him to the end of the world...
Intention: The joy and sorrow of meeting again after a long separation
