The aura of the White Stone Plains had changed.
It was not gentle and refined, nor was it refreshing.
A smile appeared on his face.
It wasn't cold.
However, it looked extremely strange and abnormal!
Kudo Shinichi couldn't help but sweat as he stared at the Shiraishi Plains.
He felt that Baishiyuan was like the strongest psychopath he had ever seen, like Professor Moriarty or Hannibal!
Seeing the sudden situation in the square, Police Officer Megure wanted to immediately go forward and stop them.
"Wait!" Kudo Shinichi pulled Officer Megami back and whispered.
"What's wrong?"
"Let's wait a little longer. The sudden change in Baishihara might be his technique!”
Techniques?
Officer Megure was stunned, listening to Kudo Shinichi.
Even he believed that Yamada Shouta-sensei was a great suspect in the murder of Saitou Mingyue.
"Yamagata Temple returned the key to the laboratory and has an indirect alibi!”"There's a security officer's testimony!" Officer Megami said.”
" Does Yamaganshoji have a sufficient alibi for the rest of the time except for the time in the laboratory?" Kudo Shinichi asked.”
"Yes!"
" Yes." Officer Megure nodded." After Yamaganshoji left the laboratory, he took another teacher's car home. He stayed at home with his wife the whole night, so he didn't have time to commit the crime."”
"Where are the cars from the mountain village temple?"
"He said there was a malfunction!" Officer Megure replied.
" It didn't malfunction earlier or later, but it just had to malfunction yesterday when Tsukiki Saitou went missing. There's a problem here!”
Kudo Shinichi pondered." He only has no alibi when he was in the laboratory. However, the indirect alibi from the security office is not enough. It can't prove anything!"”
" But the police department sent people to the laboratory to search thoroughly. They did not find Saitou Akira's body in the laboratory!”
Officer Megure stared at the trembling Yamaganshoji and said in disbelief,"
"If Mr. Yamada Shotera-sensei really did murder Akira Saitou, there would definitely be blood in the laboratory!”
"The forensic doctor used specialized testing methods and used Luminol reagent, but he didn't find any blood!”
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 not only reduce Luminol's reaction but not eliminate it.
Therefore, the Lumino reagent reaction test was a great tool for criminal investigation!
"How do you explain this?"
"This is also what I'm puzzled about. I'm not sure yet!”
Kudo Shinichi shook his head and whispered,"
"Let's take a look at Shiroshihara for now. The police department can wait for a cigarette's time!”
...........
Imperial Pill High School, square.
Countless gazes were cast over, but they did not give Yamada Shouta any sense of security.
Because no one dared to stop him.
There weren't even any policemen from the police department!
Could it be that all of them were afraid of White Stone Plain?
Afraid that he was a psychopath and a murderer?
No, all of this was a disguise!
Yamagoji tried his best to maintain his rationality, but his body could not help but tremble when he faced Shiraishihara.
"Baishihara, who are you?”Mountain Village Temple shouted.
"I am Baishihara!" Shiraishihara's fingers brushed across Yamada Shoji's swollen face, making Yamada Shoji feel as if there was a centipede crawling on his face. He shuddered.
"What do you want to do? I didn't kill anyone!”Mountain Village Temple's hair stood on end.
"You can hide it from the police department, but can you hide it from me?”Shiroishi Hara looked disdainfully at the mountain village temple."I'm far more terrifying than you think!"
"You killed Akira Saitou!”
"Or perhaps, you killed Saitou Mingyue because of your relationship issues!”
"I didn't kill Akira Saitou. I don't know what you're talking about.”
"During that time, I was in the laboratory!”
Yamagoji did not look into Shiraishihara's eyes and forced himself to calm down.
"Oh?" "You didn't kill anyone, so why didn't the police stop me?" Shiroshihara chuckled.”
"They have already started to suspect you!”
"The surveillance cameras in the laboratory are old and out of repair, and there's an insufficient alibi. These are all your doubts!”
Yamagata Shūji felt that he had gradually regained his rationality and was no longer so afraid. He gritted his teeth and said loudly,
"If I really did murder Akira Saitou, why isn't there any blood in the lab?”
"The laboratory is so small, how could it hide Saitou Akatsuki's body?”
Shiroishi Hara did not answer. He gently blew at the cigarette between his fingers.
Faint white smoke rose from the scarlet cigarette butt and filled the air, causing Yamada Shoji to panic.
Shiroishi Hara never smoked, but he looked at the smoke with an intoxicated expression.
"Are you sure you want me to tell you the reason? The cigarette is almost half-burnt.”
"I didn't kill anyone. Otherwise, the police department would have found out with the Luminol reagent, but there's no blood in my laboratory!”Shan Tianzhuang Temple continued to argue.
Kudo Shinichi frowned.
Shiroishi Hara-senpai seemed to have gone overboard.
Even if the police officers of the police department were not very good at reasoning, how could they not be careful at the scene of the crime?
As long as the Yamago-ji killed someone, there would definitely be blood left behind, and it would not be able to escape the test of Lumino's reagent.
"There are no traces of blood in your laboratory because the blood left behind by your murder has been cleaned up.”
" The Luminol reagent is a common method used by forensics," Shiroishi Hara said calmly." Because of its chemical properties, it's very difficult to eliminate it. Even if you search on the Internet, it's hard to find an elimination method!”
"But you 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!”
The mountain village temple stood rooted to the ground, completely dumbfounded.
How did Shiroishi Hara know that his actions had eliminated Lumino's reaction?
Kudo Shinichi's body trembled as if he had been electrocuted when he heard Shiraishi Hara's words.
Dealing with Lumino's reaction was something he had not considered.
If it was really as Shiroshihara said, that the chemical properties of Luminol could be neutralized, the investigation would be completely reversed.
Kudo Shinichi took a deep breath and instructed Officer Megami,"
"Ask the forensic doctor from the police department to see if he can neutralize Lumino's reaction!”
Officer Megure summoned the forensic doctor and received an affirmative answer. It was indeed possible to neutralize the chemical reaction of Luminol.
"Why didn't you consider this before?”Kudo Shinichi asked the inexperienced forensic doctor.
"Even if the mountain village temple did this, I think it would be very difficult to hide the corpse. I think the possibility of transporting the corpse away is very small!”the forensic doctor replied.
"Smart aleck!" Kudo Shinichi didn't hold back his criticism.
Shantian Zhuangsi was already panicking and swallowing his saliva crazily.
"I don't know what neutralising effect Luminol reagent has. I didn't kill Saitou Akira!”
" And even if Lumino's reaction can be dispelled, where did Saitou Akatsuki go? Such a big person can't possibly disappear!”
"There's only one way to hide a corpse. You dismembered her!”
"I think the body parts are still hidden somewhere in the school!"”
Dismember the body?
Kudo Shinichi was shocked, but he immediately felt that it was impossible!
How could this be?
