The Abyss Episode 17

Mo Bei is released due to lack of evidence, though Lu Fan notes his special forces background. Ning Zhen and Lu Fan investigate the Jiang siblings' past rivalry and Jiang Xiao's fear of Jiang Yan. They also link a series of unsolved disappearances of women with psychological issues (including Ning Zhen's mother) to the time of the Cangbei Naked Corpse Case. Their investigation leads them to Qiao En, whose sister disappeared after a Jiang Group drug trial, and reveals his connection to psychologist Luo Yin, raising suspicions about the doctor, especially when his travel dates align with the Cangbei case. Meanwhile, Wu Ke Ran is discharged, raises Cao Jin's suspicions with her attitude towards Jiang Xiao's fate, and is later attacked by Mo Bei. Cao Jin rescues her and takes her home. Wu Ke Ran overhears Lu Fan's theory about Jiang Yan and realizes Jiang Yan likely sent Mo Bei. Tormented, she secretly messages Shen Yuan. Ning Zhen and Lu Fan suspect Jiang Yan's laptop holds crucial evidence about the drug trials, but Cao Jin blocks their immediate investigation for safety reasons. (Source: tvrili.com)
