The Abyss Episode 20

Ning Zhen and Lu Fan try to trick Mo Bei into revealing a body's burial location, but Mo Bei stays alert, evades their initial attempts, and even gets temporarily detained by Cao Jin before being released due to a convenient confession from someone else. Mo Bei uses refrigerated trucks in his movements, further complicating the chase. Although Ning Zhen and Lu Fan eventually deduce a potential burial area based on truck routes and find disturbed ground, the body unearthed by the police is not Ning Zhen's mother. With no direct evidence against Jiang Yan, Ning Zhen faces renewed pressure from the mysterious Shen Yuan to accept his violent methods for dealing with Jiang Yan, but she remains committed to achieving justice through legal means.
