Lu Chen, a seventeen-year-old boy, suddenly encountered bad luck after taking the final exam in the summer of his second year of high school. His parents were killed in a fire, his sister's life and death were uncertain in a car accident when she was taking him to escape, and he was even framed and imprisoned. In prison, the mysterious "immortal old prisoner" Xuan Jin took a fancy to him and accepted him as a closed disciple. Six years later, Lu Chen, who had learned some skills, was released from prison early and embarked on the road of revenge. However, after every grudge, he found himself falling into a deeper conspiracy, as if he was a pawn manipulated by the mastermind behind the scenes. In order to find out the truth and seek justice for his relatives, Lu Chen had to go deep into the puzzle woven by the mysterious organization "Dark Abyss" and find hope of breaking through the lies and betrayal, even if there was endless darkness and danger ahead.
