[Copyable Tag: Detective]

[Effect: Acquisition of deductive reasoning]

Five very simple words, seemingly unremarkable at first glance.

But Li En knew what the term "deductive method" meant.

This is a reasoning method used by Sherlock Holmes, namely "to deduce the complete chain of facts from subtle clues at the scene," which means first observing the details, then integrating the clues to arrive at the only reasonable conclusion.

Although Sherlock Holmes is a fictional character, his reasoning method still has a certain scientific basis.

The only thing that can limit this method of reasoning is the number of details observed.

"Deductive reasoning... This effect certainly lives up to the label of a detective."

Li En remained expressionless and incorporated the label into his copying process.

If he had this labeling ability, perhaps he could deduce the relationship between his father and that London serial killer.

Please maintain a close and stable distance from your target.

Half an hour is acceptable.

"Let's wait until that Oxford professor arrives before we proceed with the next step," Joel said, pulling up a chair for Li En. "You can sit here and rest for a while, or look at the files."

Li En responded and obediently found a relatively close spot to sit down, ensuring the copying process proceeded smoothly.

Joel immersed himself in the investigation, and a large number of case files were dumped on the table. Although the environment was quite messy, the officers worked in an orderly manner, and there was no behavior that hindered their work.

This also proves, from another perspective, that Joel Greg, as sheriff, was highly competent in guiding the work.

Not long after, a dark brown sheep burst through the door of the criminal investigation office, barging in with a violent cough.

"Cough cough cough... This is terrible! The pollution in London is like a stain on Britain's face!"

Upon closer inspection, Li En realized that it wasn't a dark brown sheep, but a middle-aged gentleman wearing a dark brown wool coat.

With his dark bow tie and straight trousers matching his coat, he really did look like a chubby sheep at first glance.

The shiny leather shoes on her feet were sheep's hooves.

"Hello, Professor Parker," Joel greeted the Oxford professor respectfully, "It's kind of you to come all the way from Oxford. We really need your help."

Professor Parker stated frankly, "If it weren't for His Majesty's public criticism, I probably wouldn't have come. If this case is solved with my assistance, remember to report my name."

"Understood, of course," Joel nodded slightly, waved for Lyon to come over, and introduced him to Professor Parker, "Professor, let me introduce you. This is Lyon Wales, a theology student at Miskatonic University. He is an expert in occultism and is the assistant I specially found for you."

"An assistant?" Professor Parker looked Li En up and down, but couldn't see anything particularly outstanding about him. "Who is your mentor?"

"Ellie Enso, Cole Osborn, sir," Lee replied honestly.

Professor Parker, initially mistaking it for a person's name, paused for a moment, "Why is the name so long?"

"I have two tutors, sir."

The atmosphere was a little awkward. Professor Parker cleared his throat and changed the subject, "So it's that famous Eli Enso, who is renowned in academia but has no ability to teach students."

"None of his students have ever reached the finals of the Golden Dawn Open. He is respected in academia, but his reputation is ruined in education."

Although Li En felt that Professor Parker was right, as a student, he still had to uphold his teacher's image. "Excuse me, sir, please take back your statement. Professor Eli's teaching methods are just a bit extreme. Only truly talented students can understand his courses."

Professor Parker looked at Li En with great interest. "You mean, you're the truly gifted student?"

"If that's how you see it, then it's true," Lee En smiled politely, "I am a genius."

Coming from Oxford University, which focuses on tradition and etiquette, Professor Parker rarely sees a student as high-profile as Li En. Perhaps this is a common trait among students from Miskatonic University?

"Interesting. I hope your abilities match your boasts," Professor Parker said, not angry at all. He was more curious about Li En's true skill level. "Sheriff, let's go check on the body first."

Joel nodded, took the lead, and gestured to Professor Parker, "Please follow me."

Scotland Yard does not have a dedicated morgue, and bodies are not disposed of there.

However, due to the unusual nature of the London murder case and the unexpected nature of the incident, Joel ordered the police to leave the body behind.

After leaving the main building, the group arrived at the prison area in the courtyard.

As soon as he stepped out of the main building, Professor Parker was immediately choked by the thick gray fog and took out a handkerchief to cover his mouth and nose.

"My God," Professor Parker muttered, "this place is hell!"

splat—

He took a step forward and stepped into the wet, soft, and uneven ground. The rainwater that had not yet dried and the coal dust floating on the surface stuck to his leather shoes, covering the originally shiny surface with a layer of spots.

"Good heavens... couldn't the ground be paved a little more evenly?"

Listening to Professor Parker's complaints, Li En didn't say anything.

While Oxford also has pollution, it is mostly limited to urban pollution and household waste. Compared to London, it is indeed more like a world inhabited by living people.

After all, Oxford is not an industrial city like London, and it doesn't have such large-scale coal smoke pollution.

With its stark class divisions, severe environmental pollution, and appalling security problems, London could easily be called hell.

In order to store the body, Joel specifically requested that a cell be vacated to house it.

Although the surrounding prisoners protested, the guards would gag them with their batons.

Upon entering the cell, which had no windows, two corpses were placed side by side in the center of the cell.

There were no windows, and the only source of light was a dim gas lamp. Joel stood outside the door, blocking the remaining officers and letting Professor Parker go in first.

"Professor, I'm in trouble."

Professor Parker nodded slightly, covered his mouth and nose with a handkerchief, and leaned close to the two corpses to examine them carefully.

He pulled a jewel-like magnifying glass from his waist; it was a folding type, hanging from his waist on a thin chain, and was quite exquisite.

Using a magnifying glass, Professor Parker examined every detail of the corpses, while also lifting the white sheets covering them to inspect the wounds.

After completing all the investigation work, Professor Parker put away the magnifying glass and tucked it back into his waistband.

"Professor," Joel asked quickly upon seeing this, "have you found anything? Even just a clue that can help in solving the case would be helpful."

Professor Parker said, "I suspect this has nothing to do with the occult."

"The deceased's body was cut open with a knife, an act that does not require any knowledge of occultism."

"Of course, if you ask me whether this knife is related to mysticism, then I have no way to answer that unless you bring the weapon in front of me for me to examine."

Upon hearing Professor Parker's answer, the police officers watching outside the cell immediately let out a disappointed sound.

"Does it have nothing to do with the mysticism?"

"Is it really God punishing the wicked?"

"My God, what on earth is going on?"

After coughing twice, Professor Parker suddenly spoke up: "Of course, this is just my personal opinion; a comprehensive opinion is often the most reliable."

He then looked at Li En and said, "Mr. Wells, as Sheriff Greg's handpicked assistant, now offer your opinion. I'm curious to see what insights you can provide."

Lee turned to Joel, asking for his opinion, "Should I go take a look?"

Even a theology professor from Oxford made such a definitive judgment, so frankly, no one had any expectations for Li En.

If students were more capable than professors, wouldn't Li En have become a professor long ago?

But since the person had already been borrowed, Joel nodded.

"This is troublesome."

The moment Joel uttered his reply, the characters in Lee's vision changed.

Exactly, not a second off, not a minute off.

Fine.

Li En strode forward, the gray mist carrying coal dust, as a visible medium, brutally carrying the stench of corpses and prison cells, flowing like a river from both sides of him.

Let's play Sherlock Holmes for once.
