Wrong Interrogation Room, The First Cracked Case Shocked the World

Chapter 75: Play with psychology and defeat the psychological defense line!

"Think about it clearly—who doesn't let who off?" Ning Cheng pocketed his phone and glared at Chen Yang. The lean, stern-faced man had a sin value of 300—a significantly higher number than typical criminals, indicating multiple victims.

"What gives you the audacity to attack a police officer?" Ning Cheng sneered. "Your character flaws are glaring, Chen Yang, and now it seems your mind is also broken."

"Police? There are bad cops, too! Anyone who threatens me dies!" Chen Yang brandished a sharp scalpel. His arms, clearly well-muscled, spoke of strength. "I'll examine your heart later—see if it's black."

He advanced slowly through the darkness, a cruel grin spreading across his face. "My scalpel's specially made, razor-sharp. When it pierces your chest, it'll be quick, tearing through muscle and fascia instantly!" His body trembled with excitement.

Ning Cheng frowned. Chen Yang's behavior suggested a serious mental disorder. A normal person, caught red-handed, would flee. Instead, Chen Yang sought to kill him. This feverish desire to kill was a classic sign of psychopathy.

Nearby, Zhao Xiaoli trembled, fighting back her fear. Ning Cheng posed no threat to Chen Yang, but to a 23-year-old high school student like her, he was terrifying. He'd already killed twice, and his perverse demeanor sent shivers down her spine.

Ning Cheng watched Chen Yang approach, saying calmly, "I warn you, drop the scalpel. I can spare you the pain."

"Police are human, too. One slice to the carotid artery, and you're dead!" Chen Yang laughed maniacally.

"Stupid." Ning Cheng drew his service pistol, aiming it at Chen Yang. "I'm not a powerless woman. I'm a police officer. What gives you the right to threaten me with a knife?" The scalpel murder case had made national headlines, hence the officers' authorization to carry firearms for self-defense. While Ning Cheng was exceptionally capable, he preferred using a gun when appropriate—it saved time and effort.

Chen Yang froze, his face darkening. He hesitated.

"Stupid, why don't you attack?" Ning Cheng reminded him of the victims, his voice cold. "You only target defenseless women? Show me some courage and attack a man!"

"I'm a waste, you're right, Officer!" Chen Yang, calmer now, smirked. "I haven't killed a man...yet. You'll be the first."

He lunged at Ning Cheng, scalpel in hand. Ning Cheng wasn't surprised. A normal murderer wouldn't be so brazen when facing a gun. But Chen Yang was a psychopath, unpredictable and irrational.

Ning Cheng holstered his pistol. He didn't want to injure Chen Yang and waste time with hospital procedures and interrogations. Psychopaths required unconventional methods.

"Go to hell!" Chen Yang roared, eyes gleaming with anticipation.

"Officer Ning, watch out!" Zhao Xiaoli gasped, paralyzed with fear.

"Amateur." Ning Cheng met Chen Yang's attack with a powerful kick, sending him flying four or five meters. The impact sounded like a gunshot, knocking Chen Yang unconscious.

Zhao Xiaoli stared, stunned. One kick had incapacitated him. It felt like a movie scene. Officer Ning was incredibly strong and reassuring.

Blood foamed at Chen Yang's mouth. He couldn't rise. He looked at Ning Cheng, a proud smile playing on his lips. A taunt. He'd killed two, and he'd been caught. He'd succeeded.

"Proud of killing two women?" Ning Cheng's voice cut through the darkness.

Chen Yang searched for the source, finally realizing it was Ning Cheng. His demeanor had shifted—wild and unpredictable, the killing intent palpable. Chen Yang's eyes widened. He recognized that temperament—it was his own. Had the officer succumbed to the same madness? The thought filled him with a perverse joy. But his smile faltered as Ning Cheng picked up the fallen scalpel, moving it slowly towards his neck.

Death wasn't the fear. As a former surgeon, he was accustomed to life and death. But Ning Cheng's madness, his superior perversion, terrified him. He was facing a predator at the top of the food chain.

"Do you know who I am?" Ning Cheng raised the scalpel, the reflection in its polished surface glinting in his eyes. "I am the real scalpel killer!"

Chen Yang recoiled. His face reddened, his throat constricting.

"Your methods are pathetic, your 'heart harvesting' a poor imitation! You're crude, disgusting, like a sewer rat!"

Chen Yang's defenses crumbled. His body shook, his face flushed, gasping for air. He whimpered, his head bowing in submission.

Zhao Xiaoli covered her mouth, suppressing a scream. The scene was bizarre and terrifying. She would have fled if she hadn't been paralyzed by fear. Ning Cheng's madness was more psychopathic than Chen Yang's. She feared Ning Cheng had used some hypnotic power, and she might have obeyed him willingly.

"Enjoying being a plaything, Chen Yang?" Ning Cheng sneered.

Chen Yang looked up in disbelief. Ning Cheng's madness had vanished, replaced by calm control. It had all been an act.

"Death isn't so bad for someone like you. You enjoy toying with your victims, so I'll give you a taste of your own medicine."

Ning Cheng showed no mercy. The scene would haunt Chen Yang's final moments. It was the ultimate mental torture.

Soon, Zhou Ziyan and her team arrived, arresting Chen Yang.

"What happened? He's injured. Did you beat him?"

Ning Cheng nodded. "He tried to kill me after discovering I was investigating him."

"A madman!" Zhou Ziyan exclaimed, surprised by Chen Yang's audacity.

"He's alright," Zhou Ziyan asked, concerned.

"Besides confirming his guilt, we also determined his motives," Ning Cheng said.

"What were they?"

Zhao Xiaoli pleaded, "Officer Ning, why did Chen Yang kill my mother?"

"He killed your mother, Wang Shuzhen, because of her profession, a betrayal of sorts. And Li Rongfang, the second victim, was killed because of her perceived laziness."

"Lust and sloth," Zhou Ziyan gasped. "The seven deadly sins!"

Ning Cheng nodded. "He had a perfect life, yet he was mentally ill, disregarding life, playing God, judging others' worthiness to live."

"The seven deadly sins. Thank goodness he was caught," Mu Xiaoyu said. "Five more victims could have died."

"Why my mother? She didn't choose that career," Zhao Xiaoli whispered, tears falling.

Silence fell. Chen Yang was a psychopath who killed for pleasure. Hell was his only fitting destination.
