At this moment, how could she not understand what Xu Lin meant.
"Wait...what kind of knife is so sharp?"
"Even if our..."
Suddenly, Lin Xiangxiang raised his head suddenly and thought of a joke he had made with his colleagues.
Maybe, there really is a kind of knife that can hurt people without seeing the wound.
She calmed her breathing slightly, looked at Xu Lin and said, "I wonder if Officer Xu has ever heard of a thing called obsidian."
obsidian?
Xu Lin was stunned and said, "I have heard of this kind of ore, but what does it have to do with the case I want to investigate?"
Lin Xiangxiang said: "We once saw in a magazine that the sharpness of obsidian can reach the nanometer level. In other words, this thing can completely cut molecules."
"A knife that can cut molecules can injure people without bleeding, and there is no problem at all. Coupled with a small amount of thromboxane, the moment the aorta is cut, the amount of bleeding in the aorta will be minimal due to the action of thromboxane. "
"But this amount of bleeding is fine for a short period of time. At most, you can see some red spots around the epidermal tissue. But the rupture of the aorta is there. After a while, the artery will definitely burst completely."
"This may cause delayed death like the video you just showed me, Officer Xu."
Snapped!
Xu Lin clapped his hands fiercely and used the obsidian knife to cut atoms... How terrifying is this?
No wonder, no wonder he couldn't figure out that the culprit of all this was such a high-tech weapon.
He shook his head and sighed: "It seems that we have to keep pace with the times and learn more about this kind of technological weapons, otherwise we will be repeatedly frustrated when handling cases in the future."
When Lin Xiangxiang heard what he said, he immediately shook his head and said, "No, Officer Xu, you are wrong. This is not high technology."
Xu Lin was stunned and looked at her doubtfully.
Lin Xiangxiang: "In fact, we humans have been using obsidian knives a long time ago, and they have been widely used. However, with the development of the steel industry and finishing technology, this has gradually withdrawn from the stage of history. Today's obsidian, except for some Except for researchers in the field, they are often used as decorations, such as beads, carved pendants, etc.”
Hearing his words, Xu Lin nodded immediately.
He smiled and nodded to Lin Xiangxiang, then said goodbye and left together with Chen Yan.
After leaving Renai Hospital, Xu Lin immediately said: "Chen Yan, immediately mobilize all the criminal police, film police, law enforcement teams, etc. in the city to search for obsidian-related manufacturing companies. I want to find everyone related to this industry. information, especially craftsmen who mainly use obsidian knives.”
Although this operation is similar to finding a needle in a haystack, no matter what, this is their only important clue now.
In addition, Xu Lin also asked Chen Yan to look for relevant evidence on thromboxane.
Once found, the murderer is not far away from surfacing.
"Yes!" As Xu Lin issued the order, Chen Yan immediately started making phone calls.
As the police in Magic City began to take action, this terrifying machine rotated rapidly, and everyone related to Obsidian was investigated.
Xu Lin's goal is very obvious. Anyone related to obsidian, whether you are a collector or a producer, must go through detailed inquiries.
The most important thing is that those who have had contact with Zheng Zhong and Wang Min are especially included in the list of key suspects.
Soon, suspects jumped out one by one.
After a day of statistics, the police finally sorted out the suspects. There were 14 people in total, 9 of whom had collected obsidian knives. After testing, the obsidian knives they collected were capable of killing without blood. situation.
In addition, there are 5 people who are directly related to Zheng Zhong and Wang Min.
These five people have become the targets of Xu Lin's investigation.
Zhang Ziliang is a well-known entrepreneur in Magic City. However, due to poor management, his company went bankrupt two years ago and now he relies on delivering food to support his family.
Hong Chen, a retired cadre in Magic City, likes to collect obsidian. He has been in contact with Zheng Zhong and Wang Min, and according to some insiders, the relationship between the two parties is not shallow.
Xu Lin was sitting in the office of the Municipal Bureau, looking at the files in his hand. After reading them, he immediately raised his head and said to Ren Han: "Team Ren, please come in one by one!"
"Okay!" Ren Han nodded and immediately prepared to go out and bring someone in.
But at this moment, Chen Yan hurried in, holding a metal box in his hand and his eyes full of joy.
"Found it, found it!"
He shouted loudly, startling Xu Lin in the office.
"What did you find?" Xu Lin looked up in confusion.
Chen Yan ran up to him, quickly put the box in his hand on the table, and carefully opened the box. Soon, a crystal dagger that was as black as ink appeared in everyone's sight.
Looking at the sharp blade, everyone was stunned, and then looked at Chen Yan in disbelief.
"It was found in the home of the wealthy Wang Jintian. He also likes to collect obsidian. We also extracted the victim's blood from this knife. After extraction, it was confirmed that it came from the deceased Wang Min."
He said it very excitedly, and Ren Han also looked at the crystal-like short knife very excitedly.
Asked: "Has the person been captured?"
Chen Yan: "It's under control and can be captured at any time."
Xu Lin frowned and said, "Don't worry, don't arrest him yet, it's not him."
After this short sentence came out, everyone was stunned. The evidence chain was so complete, how could it not be him?
Everyone turned their doubtful eyes to him, wanting to hear an explanation from him.
Xu Lin looked at them and said calmly: "The test showed that there were traces of the victim's blood, so is there any lectin on it?"
After hearing his words, everyone was slightly stunned.
Chen Yan shook his head: "No."
"Not even the coagulin was left behind. Do you think the murderer would leave blood stains? And the most important point is, don't forget, this knife kills people without blood. It can't even get a drop of blood on it."
As soon as this statement came out, everyone reacted suddenly.
yes!
The knife was so fast that it couldn't get a drop of blood on it. If it was cut instantly, nothing would get on it.
How is it possible that there are still blood stains on such a knife?
Xu Lin showed a sneer at this time: "It's interesting! This murderer still wants to frame up and use the rich man as a scapegoat? He also wants to trick us around. He must also have this ability."
As he spoke, a cold light flashed in his eyes, and he said, "Let's go meet that rich man."
