Perfect Ruling

On a rainy night, Lu Chen opened the door of his house and his family was silenced. The police hastily concluded the case as a "house invasion and robbery", but the name of the real culprit was quietly erased by the powerful. After ten years of dormancy, he tempered his hatred into a blade and used extremely cruel methods to eliminate his enemies one by one - the mastermind of the family extermination case, the forensic doctor who gave false testimony, and the killer himself. That night when his revenge was avenged, he stood in front of his family's grave, only to see countless villains on the news who had escaped legal punishment and were still laughing unbridled. Lu Chen puts on his night clothes and becomes a "dark night law enforcer" who walks outside the law, specializing in killing evildoers who have solid evidence but rely on power and money to escape crime. Detective female police officer Su Wan was ordered to track down a series of murders, but she didn't know that her beloved auto mechanic boyfriend was the real murderer she tried her best to catch. Hunting and protection, suspicion and trust, justice and lynching - the two test each step at the intersection of darkness and light, until the truth puts their love on trial.
