The Abyss Episode 22

Lu Fan wakes up handcuffed by Ning Zhen, who needs his car to investigate Mo Bei's supposed burial site. After a scuffle, Lu Fan takes charge, confronts Jiang Yan's men, and uses their car. Ning Zhen deduces Mo Bei couldn't have buried a body where they thought, leading Lu Fan to the Jiang Corporation. Cao Jin arrives as Lu Fan uncovers human remains, later confirmed by DNA to include Ning Zhen's mother. Lu Fan shares this with Ning Zhen, who, triggered by her mother's belongings, revisits her old home. A flashback reveals that her mother, a cleaner for Jiang Corp, discovered issues with their drug trials, was given a USB of evidence by Lu Fan's father, hid it, and was later murdered by Mo Bei along with Ning Zhen's alcoholic father, who had tried to profit from the situation. In the present, Ning Zhen finds the USB, evades Lu Fan, who then gives the USB to Cao Jin. Ning Zhen meets Luo Yin, not denying an allegiance to Shen Yuan. The episode ends by highlighting that Qiao En had an alibi for Li Guo Kun's murder, meaning his accomplice was the killer. (Source: tvrili.com)
