Criminal Investigation: Forbidden Rose

Leng Xiangrong died suddenly in a fitness club under the "Black Diamond" club in the CBD center of Yan'an City.Unlike regular gyms, this gym is only open to Black Diamond membership card holders.The annual fee of the Black Diamond Club is tens of thousands a year, money alone is not enough, and a certain social status is also required.Rather than saying that this is a "gym", it is better to say that this is a social place for the upper class of Yan'an City after work.

After one and a half months, Xia Yi retrieved the surveillance footage from the day of Leng Xiangrong's accident again.The location of the treadmill Leng Xiangrong chose was not good, and it was not covered by the camera, but there was a camera in the corridor that captured him.That day, he was wearing tight sportswear and walking towards the aerobic area with a bottle of water in his hand-if there is any useful clue to be found, it is that when the camera zooms in, it can be found that Leng Xiangrong was wearing a A pair of "Tengfei" wireless earphones.In terms of style, it is the same as Kang Cheng, it is the latest 6.0 luxury version.

However, Leng Xiangrong did not perform an autopsy after his death.

He is 45 years old. He is usually busy with work and often works overtime. At the same time, he suffers from high blood pressure, high blood lipids, and high blood sugar. His father died of a stroke very early.It is not uncommon for this kind of gold collar to die suddenly, so it is a pity that no one has ever doubted the cause of his death.

Until now, Leng Xiangrong has turned into a box of ashes and buried in the ground.No matter how advanced modern medicine is, it is impossible to "rejuvenate" to find out more information from these ashes.At that time, Leng Xiangrong's belongings, including the earphone, were also burned by his wife.

Therefore, there is no longer anything to prove whether Leng Xiangrong died of an ordinary cardiac arrest or, like Kang Cheng, received an electric shock on his head.

The police asked around, including Shen Kaiwen, no one knew where Kang Cheng's wireless earphones came from. After all, for a fashionista like him, it's normal to buy an internet celebrity earphone.As for Leng Xiangrong, he is usually too busy with work, and his wife may not see him once a week, and he doesn't know anything about her husband's life.In the end, when it came to Tengfei, the earphones with capacitors were totally unrecognizable.The company claims that the products are processed on an assembly line, and there are countless distributors all over the country. If there is any modification, it must be installed later, and the company is not responsible.

The case again stalled.

……

Thinking of Leng Xiangrong, Shao Lin tossed and turned, unable to sleep.

He instinctively felt that this couldn't be a coincidence.But why?

Shao Lin opened his eyes, seeing the light leaking from a curtain on the dark ceiling of the bedroom.But when you close your eyes, you will see a long and dense list in front of you—the survivors of the Penglai Princess.

In black and white, every stroke is so clear.Those names were twisted and entangled into a gloomy net, imprisoning him in it.

Why do you still have to remember?Why?

Many times, Shao Lin didn't know whether his damn memory was a blessing or a torture.He turned over in pain and buried his head under the pillow, but he still couldn't get rid of the picture in his mind.He was obviously very sleepy, but the taut string was still pulling him to prevent him from falling asleep.

The red Arabic numerals on the electronic clock silently displayed - 2:34 AM.

Shao Lin finally got up and took out a small white medicine bottle from the bedside drawer.

He quietly opened the door, intending to go to the kitchen to pour some water, but found a warm yellow standing lamp was still on in the corner of the living room. Xia Yi did not go back to his room, but lay on the sofa, with one hand hanging down on the floor and the other folded on the sofa. A copy of "Network Reconnaissance Tool Application" was hung upside down on his chest.

Silly.

Shao Lin frowned slightly.

His eyes fell on the sofa, which hadn't been cleaned up for a few days, and the living room seemed to have been demolished again.Xia Yi, on the other hand, breathed evenly, leaning on the cushion, and slept soundly.Shao Lin shook his head helplessly, went to Xia Yi's bedroom to pick up a blanket, tiptoed forward, and wanted to cover it up.But who would have thought that at this moment, as if he had stepped on a landmine, there was a crisp sound—"Gah!!!"—that was especially loud in the silent living room.

The two were startled at the same time.

Xia Yi jumped up from the sofa, but it was a conditioned reflex of his muscles, and his mind was not clear enough, so he shouted with blurred eyes: "I want to eat roast duck!!!"

Shao Lin removed the coat on the ground with his feet, and found a little yellow duck hidden under it, and angrily smeared the blanket on Xia Yi's face: "Eat your uncle!"

The blanket covered Xia Yi, and he spread his hands like a ghost: "Why haven't you slept yet?"

Shao Lin was upset: "I can't sleep."

"Oh. I just read and studied, and I fell asleep after reading it for a while." Xia Yi pointed to the book on the floor, "Do you want to try it?"

Shao Lin glanced at it, and the book was only turned to the tenth page, half the page was soaked with saliva.He thought silently, what kind of talent is it to fall asleep instantly after reading a book? If everyone is like this, the world will not be peaceful.

Shao Lin didn't bother to pay attention to him, turned around and was about to go to the kitchen, but was grabbed by Xia Yi: "Huh? What are you holding in your hand?"

Shao Lin clenched his fists, not wanting to be seen.

But Xia Yi's eyes were sharp, and his expression changed suddenly: "Why are you taking sleeping pills? Do you usually rely on this to sleep? How long have you been taking it? It's not good to take this!"

"I didn't. I—just today—don't eat normally." Shao Lin tried to break free from his hand, but in the end his hand was not as strong as Xia Yi, so someone broke his hand and snatched it away.

Xia Yi shook the medicine bottle, the voice inside was crisp and clear, and there were only a few tablets left, and she frowned immediately: "It's a lie, the bottle is almost finished. Do you think it's sugar?"

Shao Lin: "..."

He leaned back, sank heavily into the sofa, inserted his hands into his temples, and cursed fiercely in his heart: that damned screaming duck.He was obviously very sleepy, but he just couldn't sleep, and his head hurt like hell.

Xia Yi's tone was quite serious: "I confiscated the medicine."

Shao Lin looked at his face as if he was facing a formidable enemy, and suddenly felt annoyed and funny: "You care about me?"

Xia Yi scratched his head, sat down next to the person with his shoulder next to him, and told Shao Lin a story.He said that there was a senior in his previous team. When he was on a mission, he unfortunately witnessed his comrade-in-arms die in front of his own eyes, and was even blown out of his face by his comrade-in-arms' brains.After returning, the senior has not slowed down.At first, I couldn't sleep and took sleeping pills, but later, I couldn't quit the sleeping pills anymore.Because of psychological problems, the senior retired early, but it is still difficult to integrate into the life of normal people.When the sleeping pills were not enough to satisfy him, the senior started to drink too much, and got into some things that shouldn't be...

No one expected that the comrades-in-arms who once depended on each other for their lives would meet again at the anti-drug scene.

That day, Xia Yi checked his ID card three times, but almost didn't recognize him.Xia Yi didn't understand those mental illnesses, but he thought at the time that if he could turn back time once, he would have snatched the sleeping pill from his hand at the very beginning.

Shao Lin was silent.

In fact, he also knows that ordinary insomnia patients are fine, and PTSD patients have a probability of more than 50% to develop substance abuse, which is simply a downward slope with no end in sight.But understanding is understanding, and insomnia is torture after all.Shao Lin blinked, and his tone was flattering: "Understood, I will pay attention. You give me the medicine first, and I will quit tomorrow—"

"Today." Xia Yi was decisive, "Shao Lin, there is no tomorrow. Today."

Shao Lin: "..."

Xia Yi shook the medicine bottle in front of people, and Shao Lin subconsciously reached out to grab it.But Xia Yi acted like a magic trick, which caught him off guard.He reached out and patted Shao Lin's head vigorously, and said in a low voice, "Don't think about relying on drugs."

Xia Yi looked at Shao Lin seriously, with light in his eyes: "Depend on yourself."

Shao Lin looked at him silently, but he actually agreed with the other party's words in his heart.However, in the end, he still couldn't help rolling his eyes, got up and walked to his room.

Unexpectedly, Xia Yi also followed all the way in.

Shao Lin was helpless: "What do you want to do?"

Xia Yi blinked: "Drowsy bugs are contagious, you know? Just like fleas."

Shao Lin: "........."

Xia Yi didn't know what special talent he had. As soon as his head touched the pillow, he could fall asleep instantly on the spot.Shao Lin looked at his side face quietly in the dark, and with every breath, there was a smell that didn't belong to him on the bed.The fragrance of the shower gel is mixed with a faint, warm, body smell. Shao Lin can't tell what it looks like, but feels that it is highly recognizable, but it is inexplicably stable.

Unexpectedly, the contagious ability of this sleepy bug was quite strong. Shao Lin miraculously fell asleep, and when he woke up, he was still full of energy and his thinking was very clear.

Kang Cheng, and Leng Xiangrong...

According to the information provided by the Internet investigation, the two have no contact on WeChat, do not usually talk on the phone, and their work schedules do not overlap - except that they are both members of the Black Diamond Club, and their investments in the stock market overlap.

But this is not enough to explain why the two died strangely one after another.

In order to obtain more clues, the police contacted the Black Diamond Club.

Among them, Shao Lin heard a piece of news——

The consumption points of the Black Diamond Club can be exchanged for many expensive things, such as first-class cabins on international flights, and Michelin restaurants that need to be reserved three months in advance. In addition, each member can also redeem one trip abroad every year.And this luxury five-day tour of Penglai Princess Coconut Country worth 48888 yuan is one of the travel packages that can be redeemed last year.

Kang Cheng and Leng Xiangrong exchanged the tickets through the Black Diamond Club!However, there was a third person—Zhuang Zhengyi, an investor of Kewei Business Incubator—who bought and exchanged the ferry tickets together.

On the surface, Zhuang Zhengyi didn't seem to have anything to do with this matter, but Xia Yi searched his resume and found that this Zhuang Zhengyi graduated from Yan'an University with a major in electronic communication, and his undergraduate graduation project was on "wireless earphones"!Regardless of the fact that wireless earphones are all over the streets, several years ago, Zhuang Zhengyi's earliest chip design was the foundation of Tengfei's wireless earphone 1.0.This design was quickly acquired by a big company at a high price, and it also made him the first pot of gold.

Since then, Zhuang Zhengyi has started the business of entrepreneurial incubation.

Xia Yi quickly locked on the target: "This person not only knows Kang Cheng and Leng Xiangrong, but also has the ability to modify earphones and add capacitors!"

The West District Bureau immediately summoned Zhuang Zhengyi.

When the police asked about the headphones of Kang Cheng and Leng Xiangrong, Zhuang Zhengyi readily admitted: "I know, the latest luxury version hadn't been officially announced at the time, and I gave them a demo at the beginning of the year."

But he was shocked by the capacitor.Zhuang Zhengyi bit him to death: "The earphones I gave them have not been unpacked, so how could there be a problem? Please let me check the earphones with the problem!"

Under the supervision of the police, Zhuang Zhengyi checked Kang Cheng's earphones.

Finally, he concluded solemnly: "I didn't give it to him. The earphones were swapped."

"Don't believe me" was written in black and white on Xia Yi's face: "How can you be sure it's a swap?"

"That's right, officer." Zhuang Zhengyi said, "Every Bluetooth device has a unique address consisting of 12 numbers and letters. This address is unique in the world, and the manufacturer needs to purchase the second half. Therefore, we The serial number of a headset matches a bluetooth address in the company system... I gave them both the 6.0beta test version, although I did not record the two serial numbers, but I know that all test samples are It starts with 000. Before the capacitor is installed in this problem, the headset is indeed a product of Tengfei Company, but the matching serial numbers of these two Bluetooth addresses all start with 225, so I can be sure that this is definitely not the product I sent The earphones for Kang Cheng. What about Leng Xiangrong's pair?"

Leng Xiangrong's earphones have been burned.

but--

At that time, there was a big screen in the aerobic exercise area of ​​the gym. In order not to disturb other people exercising, the ball game on the big screen was muted.And on the day Leng Xiangrong died suddenly, he connected his wireless earphones to the treadmill in the gym to listen to the game!

When two Bluetooth devices are paired and connected, an electronic footprint of the device is left in the source code.

With the support of network investigation technology, the police successfully recovered the Bluetooth address of Leng Xiangrong's wireless headset. Zhuang Zhengyi searched the company's system and found that the serial number of the headset started with 232.

Similarly, Leng Xiangrong's earphones were unknowingly swapped!
