"Hydrogen peroxide?"
Listening to Cheng Shi's words, Shu Yunwen still didn't understand what it meant: "...How could she wash away her sins with hydrogen peroxide?"
"Uh..." In the bathroom of the clinic, Chengshi was speechless and immediately replied: "...Hydrogen peroxide can destroy the DNA in the blood and affect the identification results. You don't even know this?"
Affect DNA test results?
Shu Yunwen was stunned for a moment, and finally understood what Cheng Shi meant——
What he found now was enough evidence to prove that Sano Izumi was the murderer, which was the blood stains on the soles of Sano Izumi's skates. If Sano Izumi used hydrogen peroxide to destroy the blood DNA, they would not be able to prove that the blood on the soles of Sano Izumi's shoes was the blood of the victim Chihiro Itami, and she might be able to get away with it smoothly...
Shu Yunwen's thoughts turned and he immediately ordered in his mind: "...Chengshi, no matter what method you use to stop her from cleaning the blood on her shoes, I will be there right away!"
"Okay, Lord Yunwen!"
Narishi responded, and Tsukamoto Sumi also noticed something strange about Shu Yunwen. He turned to look at Shu Yunwen and said, "...Yunwen-kun, what's wrong? Did something happen?"
"Well, it's nothing. It's just that Cheng Shi suddenly told me just now that the murderer wanted to destroy the evidence..." Shu Yunwen answered casually.
"Murder? Destroyed evidence?" Tsukamoto Sumi was stunned for a moment, and then immediately said, "...you just told me that the murderer was Miss Sano Izumi, right? Really, Yunwen-kun, you knew who the murderer was before, but you If you don’t tell the police quickly, you have to watch the fireworks with me... What if the murderer really destroys the evidence?"
After Tsukamoto finished his beautiful words, Shu Yunwen immediately said with a smile: "...It's okay! Anyway, the murderer can't escape. You Chengshi is staring at her. She can't even destroy the evidence... Besides, no matter how important the case is, I won't accompany you." It’s important to watch fireworks together…”
"Well..." Tsukamoto Sumi couldn't help but blush a little after listening to Shu Yunwen's words. She lowered her head and glanced at Loli Ai who was still watching the fireworks, "...I hate it, Yunwen-kun, Xiao Ai is still here..."
When Loli Ai heard this, she glanced sideways at Shu Yunwen and Tsukamoto Sumei, and the corners of her mouth twitched twice——
By the way, Shumei, do you mean to remind us that we should get away from home?
Also, you two loving dogs have been showing off in front of us since just now. Are you done with it?
Loli Ai raised her head and glanced at the fireworks exploding in the sky - well, I really want to tie these two things to the fireworks and shoot them into the sky side by side with the sun...
Loli'ai felt unhappy for a while, turned around and walked towards the skating rink hall: "...Sorry, you two continue to watch the fireworks. I'll go to the hall to take a rest."
"Well... let's go together!" Tsukamoto Sumi reached out and pulled Shu Yunwen, "... Yunwen-kun, let's not watch the fireworks and tell the police the murderer!"
"Okay." Shu Yunwen nodded, then looked at Huiyuan curiously and said, "...By the way, Huiyuan, can using hydrogen peroxide destroy the DNA in the blood?"
Huiyuan said "hmm" and then explained: "...Liquid hydrogen peroxide can alkylate with nucleophilic groups of nucleic acids and proteins, such as sulfhydryl groups, carboxyl groups, hydroxyl groups, amino groups, phosphate groups, and heterocyclic nitrogen atoms. It directly damages the DNA template, thereby affecting the DNA identification results... Can you understand what I am saying?"
When Shu Yunwen heard this, there was a black line on his forehead——
Damn it! We know you said a lot of "gay", who the hell can understand?
Sure enough, Loli Ai, you are also a scientific dog who only knows how to show your superiority! ~
…
In the bathroom of the clinic.
After Izumi Sano locked the bathroom door, he stood in front of the mirror and quickly took off the blood-stained skate. He landed on one foot and looked at the blood on the skates on the sole. A sneer appeared at the corner of his mouth, his voice was low and his expression was low. ferocious:
"...I really didn't expect that my shoes would be stained with blood. Fortunately, I found it early... Damn Chihiro and Oda, it was because of them that Narita died..."
As Sano Izumi spoke, he picked up the cotton ball and unscrewed the bottle of hydrogen peroxide. He was about to use the hydrogen peroxide to clean the blood on his shoes, but he found that the bottle of hydrogen peroxide seemed to have been hit by something and rolled directly in. into the sink, and the liquid slowly flowed into the drain...
When Sano Izumi saw this scene, his movements froze and he looked around in panic: "...What, what is going on?"
Sano Izumi felt a little hairy on her body. She looked at the remaining hydrogen peroxide in the pool, gritted her teeth, and actually sealed the drain. Then she picked up a cotton ball and soaked it in the pool. From the look of her, she seemed to be planning to wash it off. Bloodstains.
Narumi floated beside her, helplessly reaching out and patting Sano Izumi twice on the shoulder.
Feeling the power coming from her shoulders, Sano Izumi screamed "Ah", and then stumbled. She could no longer maintain her balance with one foot on the ground, her body fell sideways, her head hit the wall, and she fainted.
Narumi was stunned when he saw this, and quickly came to Sano Izumi to take a closer look, and then looked speechless——
By the way, we really just wanted to stop you from cleaning the blood, so why did you faint?
Narumi was speechless when a knock on the door suddenly sounded outside the bathroom, followed by Takagi Wataru's voice: "Hey! Miss Sano, what's wrong with you? We seemed to have heard your scream outside just now... Are you okay? Right? Sorry, I'll ask the nurse to go in and take a look..."
After Takagi Wataru finished speaking, the nurse walked into the bathroom. Then she saw Izumi Sano lying on the ground and shouted quickly.
Hearing the nurse's voice, Takagi quickly walked in, and then he and the nurse helped Sano Izumi out.
As for Cheng Shi, he honestly reported to Shu Yunwenhui: "...I'm sorry, Master Yunwen, I had an accident here... Sano Izumi fainted!~"
"What? Fainted?" Shu Yunwen was stunned for a moment at the door of the skating rink hall, "...are you scared?"
"No! She fell down on her own!"
…
In the women's bathroom where the crime occurred.
Under the leadership of the police, Komatsu Raiko, Oda Kunitomo, and Misawa Koji, who had completed the transcripts, returned here to accept police questioning.
The three people simply answered a few questions from the police, and then Oda Kunitomo suddenly asked: "...Mr. Police Officer, why hasn't Sano come over yet? Isn't her transcript finished yet?"
"Are you talking about Miss Sano Izumi? She wanted to go to the bathroom and change her shoes. We had a police officer go with her..." Officer Megure had just finished speaking. Suddenly, Takagi hurried in:
"Officer Megure, Miss Sano Izumi fainted in the toilet of the clinic just now!~"
"What?!" As soon as Takagi finished speaking, Oda Kunito's expression changed drastically and he immediately ran towards the clinic.
Komatsu Raiko and Misawa Koji also wanted to run over, but were stopped by the police. Conan asked curiously: "Mr. Oda seems to be very concerned about Miss Sano..."
"Well, of course." Komatsu Raiko nodded, and then whispered:
"...Before that incident, Oda was Koizumi's boyfriend..."
