The temperament of Ning City had changed.
A smile appeared at the corner of his mouth. It was not cold.
However, it looked extremely strange and abnormal!
Zhang Dongyang, who had just stood up in anger, was stunned. His flushed face collapsed.
Staring at Ning Cheng's strange and neurotic smile, he involuntarily took a few steps back.
It was like a lone wolf meeting a tiger at the top of the food chain.
As a murderer, if he encountered an even more perverted murderer, he would only be played!
What was going on?
A huge question mark appeared in Zhang Dongyang's mind.
Looking at Zhang Dongyang's shocked expression, Ning Cheng's smile grew wider.
As early as the second time he flipped through the files, Ning Cheng had a bold idea.
It was difficult to find evidence of Zhang Dongyang's murder using traditional methods.
He might as well crush Zhang Dongyang's psychological defense and force him to say it himself!
However, Zhang Dongyang was able to plan such a case and even withstand the police's bombardment and interrogation. His psychological quality was extraordinary.
Thus, Ning City had no choice but to break through the conventional method and adopt a performance!
With his world-class performance experience, Ning Cheng was completely capable of using this method without worrying about being seen through!
At this moment, not only was Zhang Dongyang stunned, but he also retreated in fear.
Outside the surveillance screen of Team A's interrogation room, the criminal police were also dumbfounded.
Gazing at Ning Cheng's strange and perverted aura of a murderer, they couldn't help but swallow their saliva.
"Captain Johnson, who is this Ning City guy? Is he a police officer?”
The burly policeman, who was about 1.8 meters tall, took a deep breath and said in a trembling voice,"
"Why do I feel that Ning City is scarier than all the murderers I've caught in the past!”
"It's that murderer who killed a family of six two years ago. In front of Ning City, he feels like a younger brother.”
"Phew, I think Ning City's temperament is like Hannibal!”
Zhou Ze sighed and looked at the screen,"
"Ning City is definitely a police officer. There's no doubt about it. I reckon he's up to something.”
..........
The interrogation room was brightly lit.
However, Zhang Dongyang felt like he was in a pitch-black night, and he could be swallowed by the terrifying Ning City at any moment.
"Who exactly are you?" Zhang Dongyang asked loudly.
"I'm Ning Cheng, the person who was called by the police to deal with you!”Ning Cheng said softly.
"You're not a police officer?"
"Do I look like a police officer to you?"
Ning Cheng sat in his chair and stared at Zhang Dongyang.""We're the same kind, but I'm scarier than you!”
"I know you killed someone, your wife Meier Li!”
"I didn't kill anyone. Don't play tricks here!”
Zhang Dongyang stared straight into Ning Cheng's eyes and forced himself to calm down.
However, even though he had guessed that this was all fake, his body still trembled involuntarily and panicked.
"Oh?" "You didn't kill anyone. Why are you in the police interrogation room?" Ning Cheng chuckled.”
"I was summoned to answer the questions about my wife, Mei Er Li, and her lover.”
Zhang Dongyang gradually regained his rationality and was no longer so afraid. He said loudly,
"My wife betrayed me and left with her lover. I'm here to report this to the police.”
"You believe this nonsense?"
Ning Cheng looked at Zhang Dongyang's trembling fingers and slowly picked up a box of cigarettes from the table. He took out a Chinese cigarette and said,"
"There's a faint yellowish color between your right index finger and middle finger. It looks like you're a heavy smoker.”
"I don't want to!"
Zhang Dongyang stared at Ning City and pointed at the surveillance camera."
"Don't put on an act. I know you're a police officer. Do you know that what you're doing is suspected of being induced? There's no surveillance.”
"Whether I'm a police officer or not, it's up to you. But it seems like you know the law very well ~"
"But the more it is like this, the more suspicious I am of you!”
Ning Cheng smiled leisurely, his suspicion of Zhang Dongyang deepening.
How could an ordinary person know the police interrogation process and be so familiar with the law?
Zhang Dongyang must have made preparations!
If Zhang Dongyang didn't have a guilty conscience, how could a middle school teacher like him know the law?
"Crack!"
In the interrogation room, a flame rose.
The lighter lit up the cigarette with a click. Ning Cheng did not smoke, but placed the cigarette on the edge of the table and let it burn out.
"Do you believe that I can make you confess in the time it takes for a cigarette?”
Zhang Dongyang's body had calmed down and was no longer trembling.
But at this moment.
When he heard Ning Cheng's voice and the confident smile on his face, his body trembled.
A faint white smoke rose from the scarlet cigarette butt and filled the interrogation room, making Zhang Dongyang's heart go numb.
Ning Cheng never smoked, but he looked at the smoke with a perverted expression.
"Zhang Dongyang, did you dismember and kill your wife, Li Meier, indoors?”
"No, I didn't kill anyone!"
" You've been searching my house for a long time," Zhang Dongyang said angrily." If I killed my wife at home, where did her body go?"”
"Your forensic doctor has checked. There's no trace of blood in my house!”
Outside the surveillance room, Zhou Ze and the other police officers frowned.
The brawny criminal police officer sneered and said,""Pretending to be smart! Does that Ning City think that we won't know?”
"If Zhang Dongyang killed someone at home, how could there not be blood on the floor and walls?”
"As long as there's blood left, why can't the forensics test it with the Luminol reagent?”
Luminol reagent was a commonly used blood test method for modern forensic doctors to determine the crime scene.
Using the chemical reaction of the Luminol reagent, as long as there was a little human blood on the floor, even if it was human blood that had been around for a few years, it could be detected.
Moreover, the chemical reaction of the Luminol reagent was extremely difficult to eliminate.
Ordinary people couldn't solve this problem by searching on the Internet.
This was because the methods on the Internet could only reduce Luminol's reaction, but not eliminate it.
"There are no bloodstains in your house because the bloodstains left behind by the murder have been cleaned up.”
" The Luminol reagent is a common method used by forensics," Ning Cheng said calmly." Because of its chemical properties, it's very difficult to remove it. Even if you search on the Internet, it's difficult to find a way to remove it!”
"But you, Zhang Dongyang, are a chemistry teacher. It's not difficult to remove the Luminol reaction reagent, right?”
"You just need to use a high concentration of NaClO to destroy the mutated DNA and blood protein, then use EDA to completely couple the metal ions in the blood, remove the iron ions, and then rinse it with water.
By doing so, he could completely eliminate the blood and prevent the Luminol reagent from reacting with the blood!”
Zhang Dongyang stood rooted to the ground, completely dumbfounded.
How did Ning Cheng know that he had eliminated Lumino's reaction through such an operation?
Outside the surveillance screen, the police officers looked at each other in bewilderment.
Ning City's idea was something they had never considered!
And Zhang Dongyang's profession.
Because of time.
The police did not have the time to investigate Zhang Dongyang's school. They only knew that he was a teacher from Zhang Dongyang's mouth, but they did not know the specific subjects he taught.
How did Ning Cheng know that Zhang Dongyang taught chemistry?
Zhou Ze took a deep breath and ordered,"
"Call the forensics department in the city and ask if they can eliminate Luminol's reaction according to the method of Ning City!”
"Also, call Zhang Dongyang's school and ask if he teaches chemistry.”
The two calls were quickly made, and it didn't take long for them to receive an affirmative answer.
"Captain Johnson, the forensics department said that the method used in Peace City can eliminate the blood stains and make Luminol's reaction disappear.”
"Captain Johnson, I've called Dongyang Zhang's school. Dongyang Zhang does teach chemistry.”
Two voices rang out clearly in the monitoring room.
Many criminal police officers stared blankly at Ning City in the surveillance video.
Was this still a trainee police officer?
He was clearly so handsome and so cool. He wanted to snatch their jobs!

However, according to Ning Cheng's thoughts, Zhang Dongyang was already suspected of murder.
