The steam train spewed out billowing smoke and slowly accelerated out of the platform.

Lin Xinyi also led his teammates, including Noah's Ark, to rush into the carriage aggressively before the train started.

The game finally reaches the last level.

Because of the benefits promised by the system for completing the game, Lin Xinyi now has the motivation to play this game.

He couldn't wait for Jack the Ripper to appear in front of him immediately.

But things are not simple.

Because Jack the Ripper is "missing".

It's not that he disappeared from the car, it's that he...

"He should have changed his face."

"Hidden among the passengers of this train."

Conan analyzed solemnly.

As soon as they got on the train, they saw the human skin mask that Jack the Ripper left behind when he escaped——

Disguise already exists in the world of Sherlock Holmes.

Holmes himself knew this well, and even once disguised himself as an old Italian priest in "The Final Case", with makeup so realistic that even his best friend Dr. Watson could not recognize it.

And since the Jack the Ripper in this world is related to the mysterious Moriarty, he must also have a way to learn the art of disguise.

Now on his escape route, a discarded human skin mask was found.

This shows that the face of the young coachman on the other side was completely a fake face disguised as disguise.

It may be impossible to find Jack the Ripper based on the appearance he noted down earlier.

"I see..."

Lin Xinyi understood the task of this last level.

He looked thoughtfully at Noah's Ark following him:

"Do you want us to find Jack the Ripper who changed his face and infiltrated among the passengers on this train?"

"Is this the final puzzle?"

Noah's Ark did not answer or give any prompts.

Just like a companion and an audience, I gave him an encouraging smile.

"As long as you crack this last hurdle, you can fulfill your promise just now, right?"

Lin Xinyi became very motivated when he thought of the customs clearance benefits promised by the system:

"Okay, let's go find him now!"

He immediately led his teammates to search from the last car of the train, from the back to the front, one by one to the front of the train.

There are not many carriages in this steam train.

And it was late at night, so there weren't many passengers on the bus.

Including the staff and passengers, there are only a dozen people in total.

Lin Xinyi and others used the name of the London Police, deceived and threatened them along the way, and soon gathered all the passengers they saw during the investigation.

They were brought together to a carriage at the front of the train and arranged to sit together.

"Are you kidding me?"

"Jack the Ripper, is he really among us?"

Hearing this sensational news, the passengers who were forcibly gathered together could not help but feel a little commotion.

They look at me and I look at you:

There were old men, women, young men, well-dressed gentlemen, and plain-clothed commoners.

There were all kinds of people, but they all looked ordinary and normal. None of them looked like Jack the Ripper who had just disguised himself and sneaked in.

"Everyone, please calm down."

"We will find a way to find Jack the Ripper among you."

Mao Lilan worked hard to maintain order at the scene.

Then, she tentatively asked the dozen suspects in front of her:

"Did you notice before that anyone came from the rear carriage of the train when the train was about to leave the platform?"

"This..." Everyone was silent for a while, and finally gave a disappointing answer:

"I do not see it."

"Me too, I didn't pay attention to this."

"...."

"This..." Mao Lilan turned around with some embarrassment: "Mr. Lin, what should we do now?"

She subconsciously looked at Lin Xinyi, with a look for help in her eyes.

"Well..." Conan's mood was a little subtle:

Speaking of which, I don’t know when to start...

Faced with this kind of reasoning problem, Xiaolan would subconsciously ask Lin Xinyi for help.

He even forgot that he, Kudo Shinichi, was beside him.

But this kind of N-choose-1 reasoning game that tests thinking and observation skills should obviously be the home field of a famous detective like him.

You must know that Lin Xinyi's strength is only in his knowledge reserve and practical experience in the field of criminal science, and his own mind is not much more flexible than ordinary people. This point can be seen from the fact that he was unaware of the true identity of "Jiang Shouhuang" just now.

It's already evident.

The investigation has only just begun and the clues available are limited.

Even a famous detective like himself couldn't figure it out. Could it be that Lin Xinyi could do better than him?

Xiaolan...you should ask me.

Conan children are habitually chewing on imaginary enemies in their minds...

But Lin Xinyi smiled slightly and replied confidently:

"Haha... don't worry, Miss Mori."

"There are only a dozen suspects here."

"It seems that this last hurdle is easier than I thought."

"If my prediction is correct...then Jack the Ripper should reveal his true form soon."

"Uh?" Conan was slightly startled:

He was still thinking about the solution. Why did Lin Xinyi become so confident and laugh?

This guy really figured out a way to crack it?

But this investigation has just begun...

The only clue they found after getting in the car was the human skin mask left by Jack the Ripper.

With these few clues, how did Lin Xinyi find the solution?

Could it be...

"Is there any clue? It has appeared around us a long time ago."

"But I ignored you?"

Conan couldn't help but fall into deep thought.

At this moment...

A flash of lightning flashed behind him, and an idea suddenly came to his mind:

"I see--"

"The clues should not be found on this train at all."

"The 'key' to solve this last puzzle was given to us before we even got on the train!"

Conan thought of something.

He looked down at his palm:

I saw a deep mark imprinted on the center of that young palm.

This was made with the hands and reins on the way here before -

In order to control a horse running at high speed, the driver must hold the reins tightly.

Especially at the last moment when rushing into the train station:
To be continued...
