He Jiahui came to Yutian Biotech to investigate this time because the police obtained the illegal clinical trial information of Yutian Biotech.

Yutian Biotech also suffered extortion due to illegal conduct of clinical trials.

This made He Jiahui couldn't help but start to wonder whether the two cases were related.

"Let's investigate the two cases together. Maybe we can find clues to the student union murder case in the extortion case."

Thinking of this, He Jiahui said: "What is the phone number for this blackmail? I will go back and check."

Lawyer Jiang wrote down a number, handed it to He Jiahui, and said at the same time: "Sir, as lawyers, we have some connections. I checked this phone number through connections. It is a space card, anonymous."

"Then give me a copy of the phone recording. Although the blackmailer used a voice-changing device, with today's technology, it might be possible to restore his voice," He Jiahui said.

Lawyer Jiang immediately took out a USB flash drive, handed it to He Jiahui along with his business card, and said:

"I have copied the recording, and there is also the black handbag containing the money. We also took photos and stored them in this USB disk. If Sir He needs anything else, you can contact me at any time.

In addition, I would like to remind the two sirs that the illegal clinical trials conducted by Yutian Biotech in its laboratory in India are part of the case, and according to the law, the police need to keep the case confidential."

At this time, He Jiahui finally understood why Yutian Biotech had called the police.

The police had mastered the black material of Yutian Biological, and Yutian Biological naturally did not want the police to leak this matter. So the Yutian Biological Office chose to call the police and told the police that it had been extorted because of the black material.

In this case, the black material becomes part of the case, and according to police regulations, the police need to keep the case confidential, so the police cannot leak these black materials about Yutian Bio.

Wanting to understand this, He Jiahui couldn't help but curse in his heart: "Anyone who can become a listed company is really an old fox!"

…

The two returned to the police station. Ma Jun handed over the blackmailer's phone number and the USB flash drive to his men, and then ordered:

"Yang Zai, go check this phone number."

"Cannon, there are two recordings in the USB disk. One of the people's voices has been processed. Go to the technical department and let them try to restore that voice."

After a while, Yang Zai was the first to come back and report the situation: "I checked the phone number. It's a space card. There is no user information, and this number has only been contacted by one person. This is the only number he has contacted."

Ma Jun looked at the number and said, "It's Du Yiying's mobile phone number. It seems that this space card is specifically used to contact Du Yiying."

After a while, the cannon also returned from the technical department.

"The technical department has listened to those two recordings. The blackmailer probably just used an ordinary voice changer. It is not difficult to restore the original voice. It should be done within 24 hours." Cannon said.

"Then we have to wait until tomorrow to get the results." He Jiahui sighed, and then said: "Sir Ma, let's not be idle, let's go to the underground tunnel of the racecourse together!"

…

People in Hong Kong are keen on horse racing. Every racing day, Happy Valley Racecourse will usher in more than four hours of carnival.

The bright night inside the racecourse and the cheers from outsiders vividly illustrate the glamorous side of Xiangjiang. However, under the racecourse, the 150-meter-long underground tunnel is where homeless people make their homes.

As an international metropolis, Xiangjiang is very tolerant and has great competitive pressure. Places like Qiaodong and underground tunnels often become homes for homeless people.

Some of them would set up tents, some would put up cardboard boxes, and some would simply spread a piece of plastic paper and sleep on the ground.

These homeless people are not just locals, many foreign homeless people from Southeast Asia, South Asia, and even North Africa will also gather here to form a "United Nations Village".

Even some people with jobs will choose to live here. They work during the day and live in the underpass of the racecourse at night. They can wash up in the nearby public toilets or baths, which can save transportation costs and rent.

Since horse racing is a very important business card of Hong Kong, the government will clean the underground tunnels of the racecourse twice a week, and the police will come to check ID cards from time to time to see if there are any contraband. Therefore, the underground tunnels of the racecourse,

Health and public security are still guaranteed, but at most there is some petty theft.

He Jiahui and Ma Jun came to the underpass of the racecourse and found three red tents, but they were not fifty meters away from the entrance.

Fifty meters away from the entrance, there is a dilapidated sofa bed. A homeless man in his early fifties is lying on the sofa bed and yawning.

He Jiahui walked up and asked, "Sir, have you always lived here?"

"Where I live is none of your business!" the other party snorted coldly.

"I remember when I came here last time, this location was a red tent!" He Jiahui continued.

The homeless man didn't answer and just ignored He Jiahui.

Seeing this scene, He Jiahui was about to take out his police officer ID card, but Ma Jun took the lead and stood in front of He Jiaming.

Ma Jun stretched out his hand and slapped the sofa bed hard, causing the homeless man to get up immediately in shock.

"What are you talking about? Are you deaf?" Ma Jun stared at the homeless man, clenched his fists tightly, and said viciously.

Seeing Ma Jun's fierce look, the tramp immediately became arrogant and said: "Boss, I have something to say, what do you want to ask?"

"Let me ask you, was there a red tent here before?" Ma Jun asked.

"There was a red tent two days ago, but it was moved later," the homeless man replied.

"When did you move away?" Ma Jun asked again.

"I remember that when the government sent people to clean up the roadside on Tuesday, the tent was still there, but it disappeared on Wednesday morning." The homeless man replied quickly.

"Who lives in the tent? Have you seen them?" Ma Jun asked next.

"I've only seen him once. He was wearing a mask, but judging from his body shape, he should be a young man." The homeless man paused and then said, "The young man's clothes are quite new and he doesn't look like a street friend.

"

Ma Jun used the same method and asked a few homeless people nearby. After getting no other clues, the two turned around and left.

"Sir Ma, you are quite experienced in dealing with street friends like this!" He Jiahui said with a smile.

"These older street friends are each more cunning than the last. If you take out your police ID card, he might ask you for informant fees! But they are most afraid of being troubled by socialists, so scaring them directly is the most effective way.

." Ma Jun answered.

"It's a pity that no one saw what the blackmailer looked like. Now we can only place our hope on that recording."

…

The next day, the technical department repaired the recording.

Ma Jun pressed the play button, and a man's voice sounded: "Director Du, you should have received the letter from this morning, right?"

"It sounds like he is a young man. It feels a bit familiar. I seem to have heard it somewhere." He Jiahui said.

"Do you feel this way too? The more I think about it, maybe we have met this person before." Ma Jun said.

The recording continued to play: "It's the letter you should spend money on to eliminate the disaster because you caused a loss of life!"

"It doesn't matter who I am, what matters is that you caused a loss of life."

At this time, Ma Jun said fiercely: "It's Liu Baorui, the one in charge of accounting in the student union!"

After Ma Jun reminded him, He Jiahui also realized that this voice was very much like Liu Baorui's.

"When we recorded Liu Baorui's confession, there should be a video, right? Take it out immediately and compare it!" He Jiahui said.

Yang Zai immediately found the video of the time, and when everyone heard it, it was indeed the same person's voice.

He Jiahui was still worried, so he ordered: "Send these two voices to the technical department for comparison."

Yang Zai took the voice to the technical department to compare, and Ma Jun said: "Unexpectedly, the person who blackmailed Yutian Biotech was actually Liu Baorui. The case went around in a circle, but it went back to the student union. As expected, these two cases

There is a connection.”

He Jiahui said: "This Liu Baorui did not mention the dirty information about Yutian Bio when he was recording his confession. He avoided the important and ignored the trivial matter, talking about the 100,000 yuan reward from Friends of the Ocean.

It seems that he is deliberately diverting the attention of our police. Maybe he also knew the inside story about the deaths of Chen Zishuo and Fang Moxuan, but deliberately did not report it!"

"I have guessed before that Chen Zishuo and Fang Moxuan may also have dirty information about Yutian Biotech. Do you think it is possible that the extortion of Yutian Biotech was done jointly by the three of them?" Ma Jun asked.

.

"Impossible." He Jiahui shook his head: "Chen Zishuo was murdered a month ago, and Fang Moxuan was murdered a week ago. The blackmail case occurred on Monday, and both Chen Zishuo and Fang Moxuan were dead at that time."

"Or maybe they committed the crime separately? Chen Zishuo, Fang Moxuan and Liu Baorui blackmailed Yutian Biotech respectively. Chen Zishuo and Fang Moxuan were silenced because of this, but Liu Baorui was lucky and was not silenced." Ma Jun speculated.

He Jiahui shook his head again: "It's not very likely. Judging from Yutian Biotechnology's attitude, they are willing to spend money to eliminate the disaster, otherwise they wouldn't be blackmailed by Liu Baorui for one million.

Since Yutian Biotech is willing to spend money to solve Liu Baorui's blackmail, then if Chen Zishuo or Fang Moxuan goes to extort money, they will also choose to pay. Yutian Biotech is not short of these millions. Money can solve the problem, so there is no need to kill people.

"

"It may also be a matter of dividing the spoils." Ma Jun continued: "Liu Baorui felt that it was not cost-effective to divide the money between three people, so he decided to kill Chen Zishuo and Fang Moxuan, and then blackmailed Yutian Biotech, so that he could keep all the money.

Or maybe there was a disagreement between them, Chen Zishuo and Fang Moxuan were unwilling to blackmail Yutian Biotech, but Liu Baorui felt that these two people were blocking his way of making money, so he killed them!"

Ma Jun, worthy of being the senior inspector of the serious crime team, listed several possibilities in one breath.

While the two were discussing, the phone in the room rang.

Ma Jun answered the phone and Yang Zai's voice came from the receiver.

"Sir Ma, the technical department has compared the voiceprints and can confirm that the two sets of voices come from the same person." Yang Zai said.

"It's confirmed, the person who blackmailed Yutian Biotech is Liu Baorui! We can arrest him now."

…

Liu Baorui was taken to the police station again, and the police also searched Liu Baorui's residence.

"Under Liu Baorui's bed, we found a disassembled red tent and a black handbag, the same style as the photo provided by Yutian Biotech. There was one million in cash in it, all old banknotes, with a face value of 100 yuan.

Those who have one and one thousand yuan will each get one hundred yuan."
