Chapter 476: Detective Chinatown 2 (2)

"The walls of the deceased's basement were covered with steel plates. I also visited the scene and found that the interior decoration was not complicated. There was only a set of chairs, a wooden bookshelf and a small safe."

In front of many detectives, Qin Feng made an analysis calmly.

"These conditions, coupled with the bullet marks on the surrounding walls and ground, are indeed more consistent with a ricochet caused by an accidental shooting.

In addition, based on these traces, you should have also analyzed the trajectory."

He took out a laser pointer from somewhere, placed it at the place where the bullet was ejected, and started fiddling with it.

Soon, when he had done all this, with the flick of a switch, beams of lasers appeared at the virtual crime scene and eventually pointed to the same place, which was the direction where the body was standing.

"Based on these ballistics, it can be determined that the direction in which the bullet was fired is consistent with the direction in which the deceased was standing."

"That's right. It is based on this that we determined that Li Zhiyuan committed suicide."

Chen Ying nodded. However, Noda Hao, who had been observing the scene and ranked third among detectives and was in competition with Qin Feng, suddenly walked to the front and spoke while looking at the corpse.

"The autopsy showed that the angle of penetration of all bullets in the deceased's body was less than 15 degrees, and the parallelism error of the impact trajectory did not exceed 0.5 degrees.

Assuming it was a ricochet as you say..."

He waved his fan and 3D modeling special effects appeared in the air.

"According to the 2006 New York University's Indoor Bounce Probability Model, the effective killing angle of a single ricochet on a concrete wall is only 4.7 degrees.

To create eight effective ricochets in this 5.8m x 3.2m basement, and all ricochets must hit the same target——"

Noda Hao closed his eyes and did mental calculations. A bright red probability formula appeared in the air and a large number of numbers rolled. Finally, with a "swish", he threw open his folding fan, covered his mouth, and spit out a result.

“P=（4.7/360）^8≈2.7×10^-15！这相当于连续中17次强力球头奖。”

"So..." Noda Hao leaned forward and looked at Officer Chen Ying, "Do you believe that miracles exist in this world?"

"Tsk, we are staunch atheists!"

Tang Ren, with a grumpy face, suddenly inserted himself between Noda Hao and Chen Ying and helped the mixed-race female police officer out of trouble.

The audience had already noticed that Tang Ren had taken a liking to Officer Chen, and they all burst into laughter.

But Officer Chen in the movie didn’t laugh.

"Since you say Li Zhiyuan didn't commit suicide, then where is the murderer?" she retorted angrily.

Whether it was Qin Feng, Noda Hao, or other detectives at the scene, they all shut their mouths, feeling very embarrassed.

The reason why "Uncle Seven" invited so many famous detectives from Crimaster (Crime Master) to come is because this case is really difficult, extremely difficult.

The difficulty lies in this secret room.

"We can now confirm that the death was not suicide, but homicide."

Qin Feng took the initiative to stand up and spoke first:
"We can slowly think of the murder method, but we have to identify the murderer first. Otherwise, every second of delay will increase the chances of the murderer escaping."

"I have called up the surveillance cameras around the deceased's home, but due to local privacy protection regulations, the surveillance coverage is very small and there are many blind spots." Female hacker Kiko was the first to respond.

“Generally speaking, murders in closed rooms are usually committed by people who are acquaintances.

After all, the United States doesn't ban guns, and Li Zhiyuan doesn't have bodyguards around him. It's easy to kill him. There's no need to go through so much trouble for a stranger to murder. Just shoot and run. With the rate of solving shooting cases here, it's hard to catch him."

Qin Feng analyzed at this time and suddenly asked a question.

"Who was the first person to discover Li Zhiyuan?"

“It was his family’s cleaning lady, a fifty-year-old Mexican woman.

According to her confession, Li Zhiyuan hired her to clean his home three times a week.

Although Li Zhiyuan usually stays in the basement at home on weekdays, he will basically say hello to her.

But this time, Li Zhiyuan did not respond after two consecutive visits to clean the house. She realized something was wrong and called the police.”

"Does the cleaning lady have a key to the deceased's house?"

"No."

"That means the cleaning lady was not the first witness at the crime scene." Qin Feng's face was serious.

Chen Ying shook his head. "No, the first witness should be the FCF (fire brigade) member who helped break open the basement door. They opened the door and found Li's body, and then notified the police in the area."

“Generally speaking, even if the owner is missing, the local fire department should not have the right to break open the basement door of a private house at will with just a cleaner.

Shouldn't normal procedure be to try to contact the victim's family first?"

Qin Feng suddenly pointed out a suspicious point, and Chen Ying's face immediately showed embarrassment.

"Also, what about the documents in the victim's home, especially in the basement? I saw he had a bookshelf and a safe. Maybe there is something in there that might have given the murderer a motive for killing."

Qin Feng continued to ask questions, and Chen Ying became even more embarrassed.

As the plot develops to this point, even the audience who have been led by the nose have discovered that something is wrong. Li Zhiyuan’s death is not a simple murder case. There are more unspeakable things behind it.

Soon, what Chen Ying had hidden was revealed.

Female hacker Kiko hacked into the local government network system and found the firefighter who broke into Li Zhiyuan's basement door and entered the room first that day.

Time was running out, so Qin Feng and the others didn't think much about it and immediately went to look for the first witness at the crime scene.

However, the detectives soon encountered another group of foreigners wearing black suits, who looked like bodyguards or armed men.

The other party was obviously one step ahead and had already taken control of the firefighters who had entered Li Zhiyuan's basement.

Such a plot conflict naturally arose, and both sides engaged in a lively street fight. When the conflict subsided, the leader of the group appeared.

It turned out that these people were security personnel from a New York technology company called "Sapiens". The reason they wanted to control the firefighters who had entered Li Zhiyuan's home was because the company had cooperated with Li Zhiyuan.

"Dr. Li is our company's specially hired expert. Everything he researches should be considered our property!"

Chris, the deputy director of the security department of Homo sapiens, a middle-aged white man with blond hair, glasses, and a vulture-like face, walked out from behind the security guard and said to Qin Feng and others.

"So all the books and materials in the deceased's home, as well as the contents of the safe, were taken away by you!"

Qin Feng looked at the deputy director of the security department of the intelligent being, then turned his head to look at Chen Ying. The female police officer subconsciously avoided his gaze.

"That's right, the company's property is sacred and inviolable. Dr. Li accepted our funding and established his own laboratory, so his research results should naturally belong to us.

As for you weird guys..."

The deputy director of the security department of the Sapiens Company glanced at the strange-looking detectives at the scene and smiled contemptuously.

"I advise you to be honest and not violate American laws."

There was one more thing he hadn't said, which was that the Sapiens Company had a strong enough team of lawyers and deep influence and connections in the local prosecutor's system, enough to send them all to jail. As for those who were put in jail here... naturally there were plenty of ways to deal with them.

Faced with this situation, some detectives also began to retreat.

After all, as the deputy director said, personal strength is indeed not worth mentioning in front of big companies and big capital.

And the key point is that the other party obviously took action earlier than them, and all the important information, materials, and documents were in the other party's hands.

In this case, it is extremely difficult to continue investigating this case.

"What else are you investigating? The murderer must be that company dog.

This Dr. Li must have developed some very advanced high-tech, and that company wanted to keep it all to themselves, so they arranged for someone to kill him to silence him and take the research results for themselves.

The firefighters who discovered the scene were detained to keep their mouths shut and prevent the news from leaking out."

Tang Ren suddenly jumped out and expressed his own opinion.

Although it looks funny, there is some truth in what it tells.

"Yes...it's possible, but we need to know first...what exactly did Dr. Li research?"

Qin Feng stuttered and said:
"Did he...did they say that Dr. Li also has a...laboratory?"

"Dr. Li is a professor at Columbia University."

The female hacker Kiko had already found relevant information on the Internet. She took the lollipop out of her mouth and said:
“He has a position at Columbia University as the general director of the quantum computing laboratory.

Generally speaking, it is difficult for Chinese people in the American scientific community to hold such important laboratory positions and enter the core circle.

Although Dr. Li has strong scientific research capabilities, the investment from Sapiens must have been an important factor in his appointment as the head of this laboratory.”

"However, due to the pressure from Columbia University, Sapiens was unable to get involved in this laboratory."

Chen Ying suddenly said:

"But the area has been sealed off. Even our police have only been inside once, and we are not allowed to take anything away."

"I want to go and take a look at this laboratory!" Qin Feng said firmly.

What happened next was naturally that Qin Feng and Tang Ren, with the help of a group of detectives, disguised themselves as cleaning staff and sneaked into the quantum computing laboratory of Columbia University.

Naturally, they made a lot of jokes here, especially with Tang Ren's academic level. Entering a high-tech place like a laboratory, his ignorant and frightened look really made the audience laugh.

Fortunately, there is Qin Feng. Although he has not yet entered university and has just graduated from high school, he has accumulated a lot of knowledge and has read a lot of books in order to become an excellent detective.

In addition, he was not alone and had the help of other detectives outside. After some twists and turns, Qin Feng finally found some clues in this laboratory.

On the one hand, they figured out what Dr. Li was researching.

"According to the public papers available online, plus the information in the laboratory, Dr. Li is very likely researching 'quantum decryption' technology."

Qin Feng spoke with a serious face, but Tang Ren next to him was confused about the situation and couldn't understand what he said.

"What decryption? Decrypt what?"

“The so-called ‘quantum decryption’ is a hybrid decryption technology evolved from the Grover algorithm and Shor algorithm based on quantum computers.

It can find orderly patterns from disordered chaos and perform brute force cracking and dimensionality reduction attacks on any encryption system - it can compress the RSA-4096 encryption that traditional computers need millions of years to crack into 8 hours. "

Japanese detective Noda Hao suddenly spoke up to explain.

"And it's not just about brute-forcing any encryption system. Quantum decryption algorithms can even analyze any code, secret code, or even any language that exists in reality."

"You're so amazing. No wonder those people in the company want to kill Dr. Li. But I didn't expect that you, who are only a little bit more handsome than me, actually know so much."

Tang Ren made jokes at the right time, while Noda Hao looked very proud.

“Although our Noda family’s company has not been involved in quantum technology, there are still many talented people in the laboratories under its name.

Moreover, this algorithm is a hot topic in the scientific research community, and Dr. Li is not the only one working on it.”

"Dr. Li is not doing research alone. He has two assistants!"

New clues emerge, and it turns out that the deceased Dr. Li Zhiyuan had two assistants.

Qin Feng and others hurriedly investigated the whereabouts of the two people. It turned out that one of them had returned to China two months ago for graduation. And judging from the other party’s graduation thesis, that person’s research on "quantum decryption" should not be very in-depth. He chose the topic of "artificial intelligence + quantitative investment".

As for the other female assistant, her name is Lin Wanru, and she is also of Chinese descent.

Her whereabouts -

"disappeared?!"

"Yes," Chen Ying said solemnly, "After Li Zhiyuan died, we also checked the people close to him, and Lin Wanru was no exception. But when we went to look for her, she had already disappeared."

"When did you disappear?"

"It should be five days before Li Zhiyuan's accident." Chen Ying replied.

Tang Ren shouted indignantly at this time: "Is there any need to think about it? It must have been done by that company. They not only killed Dr. Li, but also kidnapped Lin Wanru."

Now all the clues point to the company called "Homo Sapiens", and the two sides have no choice but to confront each other.

However, with the strength of Qin Feng and his men, they are definitely no match for the Intelligent Company.

Fortunately, Dr. Li is not just Dr. Li.

That night, Chris, the deputy director of the Homo sapiens security department, who was wearing a black mask on his head, was tied up and brought back by the "Longqing Society" with double red sticks.

Under the interrogation of these professionals, Chris confessed everything he knew.

According to him, Li Zhiyuan was not killed by them.

"You Chinese have an idiom called 'killing the chicken to get the eggs'. Dr. Li is the chicken that lays the golden eggs. How can we kill him?"

Chris looked aggrieved and explained sincerely:

"The reason why we care so much about Dr. Li is that in the past year, many well-known scientists around the world have either committed suicide or been murdered. This is obviously abnormal."

"So Dr. Li also noticed something was wrong?" Qin Feng asked solemnly.

Chris nodded.

"Just a week before Dr. Li passed away, he found us and said...he said..."

"What did he say?"

"He said he was haunted by a 'ghost.'"
