"Nonsense!"

"That's nonsense, Jun Ito. I can sue you for defamation."

Whalei Sadao suddenly exploded and became so emotional that the gunshot wound on his hand was bleeding. "You said I was the murderer of Kameda and Xie Jiang Shijiu. What evidence do you have?"

"Just with a tennis ball?"

"Don't be ridiculous. You said you saw it slipping away under my arm. Who saw it? So many people didn't see it, but you saw it?"

"There is also a cigarette timer. This only proves that everyone present is a suspect, including you, including Officer Samezaki Shimaharu."

"Who knows if you were secretly pretending it, and then secretly killed Kameda, Xie Jiangshijiu and others according to your statement? Who can prove that you didn't forge all the notes and bullet casings?"

The sudden outburst of Whalei Sadao was completely like a rabbit in a blind corner trying to bite someone before it died.

Chen Jun looked unhurried, leaning against the railing, enjoying the sea breeze, which brought coolness and comfort. Under the night sky, the stars hung in the sky, connecting with the endless sea, like a beautiful starry sky mural.

"The starry sky is so beautiful~"

Samezaki Shimaji and others did not understand what Chen Jun meant by closing his eyes, and did not dare to disturb him.

However, it was as if Sadao Whalei had grasped something, and he kept venting his words for three minutes.

"Are you done?"

Chen Jun opened his eyes and said with great interest, "I talked longer than you just now, which made my mouth dry. Now let you experience it."

"And after all, there are so many, don't you just want all the evidence to convict you?"

"Sadao Whalei, this case is very interesting. If you want it, I will give it to you and let you die - clearly - clearly - white - white!!"

The night wind blew a strand of Chen Jun's hair under his bangs, and his sharp gaze was so intimidating that Whalei Sadao couldn't help but swallow his saliva, feeling frightened.

"What other evidence do you have?"

Officer Samezaki Shimaharu stepped forward to question. The logic of the inference just now was sufficiently self-consistent, but the evidence was indeed a bit weak.

"I am a forensic scientist, so of course I will use my professional knowledge to collect evidence!"

After Chen Jun finished speaking, he put on his medical gloves again.

Samezaki Shimaharu took a step back and took the initiative to give way to the aisle.

Chen Jun walked to Xie Jiang Shijiu's body and squatted down. Instead of inspecting the body's injuries and so on as before, he took out a bag of test strips and a row of reagents from his pocket.

He took out a piece of test paper from it, used a dropper to absorb a drop of reagent and dropped it on the test paper. The reagent component was mainly organic solution ethanol. Then he covered the test paper around the bullet hole in Xie Jiang Shijiu's temple, and then covered it with a layer of dry test paper.

This extraction process takes several minutes.

Everyone looked at each other in confusion, wondering what Chen Jun was doing.

Whalei Sadao's eyes widened, he felt inexplicably panic looking at this scene, his teeth chattered and trembled, as if he was facing a life and death arbitration.

After 3 minutes passed, Chen Jun took off the test paper.

The movements are gentle and meticulous. Even the smallest details are the key to victory or defeat in medicine, or even life or death.

"Huh~"

Chen Jun breathed out a breath, smiled softly and said, "When forensic doctors identify mechanical injuries, there is a well-known scientific cornerstone theory, that is, "when two objects come into contact, a transfer phenomenon will occur. It will take away some things, but also leave behind

Download something."]"

"Firearm shooting is no exception. During the shooting process, the firing pin hits the bullet, causing the gunpowder to burn rapidly and forming a high-pressure gas in the gun bore.

While this gas pushes the warhead away from the muzzle, it also ejects unburned gunpowder particles, gun oil, metal shavings, soot and other residues from the muzzle at high speed.

These "shooting residues" usually remain on and around the inner edge of the bullet hole, on the back of the shooter's hand, between the fingers, on the surface of the bullet, the inner wall of the barrel and the surface of related parts.

The main components of shooting residues are unburned and incompletely burned gunpowder particles (containing nitric acid and nitrite groups), metal powder (such as Cu, Pb, Fe, Zn, etc.) caused by friction between the warhead and the barrel, and percussion powder.

Combustion products (such as Ba, Sb, etc.).”

"If you want to test the shooting residue, there are generally two methods: physical and chemical testing. The advantage of the physical testing method is that it does not destroy the extracted physical evidence. The main methods include atomic absorption spectrometry, fluorescence analysis, and scanning electron microscopy.

method and medium molecule activation analysis method, etc.”

"Currently, the means are limited, so I can only use chemical methods."

Chen Jun used a dropper to absorb a drop of the solution and dropped it on the test paper he just took off. "I dropped a 1% diphenylamine sulfuric acid solution because according to the principle of gun smoke reaction, as long as the shooting residue is extracted, silver nitrate will appear.

Produce a blue reaction."

"Whalei Sadao, did you see it and react? It has been successful."

"Just now I have extracted the shooting residue from the deceased Xie Jiang Shijiu's temple. Now - I just need to extract the shooting residue from the back of your hand and test it with the solution. By comparing the two, all the truth will be clear at a glance."

"No way, that's false."

Whalei Sadao roared, and regardless of the pain in his left hand, he rubbed the back of his hand against his clothes.

"You destroyed the evidence!"

Police officer Samezakijima Haru was so strong that he knocked Whalei Sadao to the ground with one punch.

After falling to the ground, Sadao Whale finally admitted his defeat, his eyes were dull, he lowered his head and sighed, "When did you start doubting me? I thought everything was done perfectly."

Chen Jundao: "I had doubts about you when I found the charred corpse, and the reason was the watch!"

"When I boarded the boat for observation, I discovered that Mr. Xie Jiangshijiu's gold watch was worn on his right hand, while the gold watch on Kameda's body was worn on his left hand. If the murderer was Xie Jiangshijiu, he would have to

Kameda pretended to be his death, so the position of the watch cannot be wrong."

"Furthermore, your arm was injured on your right hand, so you are obviously left-handed. This habit led to errors in the position of the gold watch, which further confirms what was said above."

"As for the motive for the murder, if I am not mistaken, it should be for the money from 20 years ago."

Chen Jundao: "You held an advertisement in the name of Furukawa University to inform the other two partners that year, so that after the news passed, the three of them could receive the huge sum of 400 million yuan, and three people were needed to open the huge sum of money.

The tokens are Kameda’s Furukawa seal, Xie Jiangshiji’s key, and the signature you are holding.”

"Similarly, these three tokens are also proof of your reunion. There will be no unrecognizability due to personal plastic surgery."

"This is why you were able to quickly identify Mr. Kameda and Mr. Shijiu Xie, but at the same time, you held seals and keys to test them in front of us, which exposed this and made us suspicious."

"You're absolutely right."

"But without you, who would know about this layout?"

"No one here can see through it. As long as this day passes, no one will be able to find me after I get off the shore. It's all because of you."

"You are so terrifying, even more terrifying than Ye Caisan back then."

Whalei Sadao smiled arrogantly, as if he was in a daze, looked at Chen Jun, and said to everyone, "I'm sure you must have killed someone and committed a crime, otherwise you would never know so clearly...unless

..."

Many people at the scene just thought this was the nonsense of Sadao Whalei. Only Yukiho couldn't help but her heart beat hard. She knew it was true.

"Unless you are a god!"
