He is the prey he has been chasing for three years and his only salvation.
Shen Yu has been tracking the "Shadow" organization for three years. In order to capture the leader Lu Yuan, he lurked for four hours in the rainy night.
When he thought it was a life-and-death showdown between hunter and prey, the man put away his weapon at gunpoint, turned around and disappeared into the rain, leaving only one sentence: "Next time we meet, I will give you an answer."
The answer is twenty years of blood feud.
A file sent anonymously revealed the truth about Shen Yu's father's sacrifice - the man behind the scenes was Lu Yuan's adoptive father Feng Kande.
One is a detective who swears to defend justice, and the other is a "sinner" with the blood of the devil.
When the law and personal hatred intertwined, and when the pursuit turned into a joint effort, Shen Yu realized that Lu Yuan was walking on the edge of darkness not to do evil, but to push the real devil into the light.
"Shen Yu, trust me."
For these words, Lu Yuan stood in front of him with four guns aimed at him;
For these words, he held Shen Yu's out-of-control hand in the pool of blood at the dock.
The trigger that was not pulled on that rainy night finally turned into the light that illuminated the abyss.
——"Someone has to pay back what's due. And I want to give you a clean world."
