Lin Xi said that Chen Yingjie sneaked out of the room once made Sherlock very concerned, but Sherlock was not in a hurry to get to the bottom of it, and what he had to do now was real reasoning.

"Mr. Sherlock, if the murderer is not Xiaoying, then ......

Lin Xi looked at Sherlock with some incomprehension.

"Yes, the murderer is indeed not her, nor is it you, because you can't make the secret room, if this red line does not exist at the scene of the crime."

Sherlock casually threw the red rope on the ground, refuting all his previous speculations.

"So, that's not how the Chamber of Secrets was formed?"

Chen Yingjie was a little surprised, it was rare for such a subtle technique to be just a temporary conjecture of Sherlock, so what is the truth? Also, if the murderer is not himself and Lin Xi, isn't that the person between Luo Nan and Yan Wu? Chen Yingjie became a little nervous, looked back at the two of them, and found that their expressions were very strange.

Yan Wu bit her lip, her face was pale, Luo Nan was gloomy, there was no brilliance in her eyes, the murderer was here?

Sherlock's cough made Chen Yingjie concentrate, if the previous ones were all performances, then now it should be real reasoning, right? Everyone is looking forward to Sherlock's statement, but is it a crappy detective? Or a detective? We'll see.

"We know that the key point of this case is the secret room, how did this secret room come to be?"

Sherlock paced beside the corpse, hanging everyone's appetite, and suddenly stopped, making everyone's hearts stunned, including Watson, so far he only knew that Sherlock's psychological warfare was to obtain more information, but what was the truth of the matter? Only Sherlock himself knows.

Sherlock knocked on the window with his hand, making a "thump" sound.

"The point is here, the murderer sneaked in from here, and the tool of the crime is this rope."

Sherlock pulls out the rope he found in the grass.

"Watson and I picked it up in the grass fifty meters away. Although it was an accident to pick this up, it was not a coincidence that it appeared here, because this one was thrown out by the murderer, why should it be thrown away, I have already explained, but how to use it, do you know?"

Sherlock suddenly asked the crowd a question, but apparently no one would answer, and if he knew, wouldn't the murderer have been caught long ago?

Chen Yingjie and Lin Xi shook their heads, confused, but only Chen Yingjie and Lin Xi interacted with him, because they were not murderers, so they naturally had more leisure to guess riddles.

Sherlock straightened the rope, tugged at it, and handed it to Watson.

"Watson, you've got rock climbing experience, right?"

Watson nodded, but he was a little puzzled, didn't Sherlock know about it? Why did he ask, but he immediately understood, after all, he had handled a lot of cases with Sherlock, and Sherlock wanted to tell others at this time.

"Please tie yourself around your waist with a rope and come down from the window of 301 upstairs, and stay directly above window 201."

Sherlock instructed him to do so, and took the key to 301 off the keyring and handed it to Watson. Watson nodded and took the key, and without asking why, he went straight out.

Sherlock didn't plan to stare at Luo Nan anymore at this time, this was a man's gentleness, but even if he didn't look at it, he knew what Luo Nan's expression was at this time.

"Mr. Sherlock, you mean the killer went out of 301's window and then used a rope to enter 201?"

Lin Xi raised his doubts, and Sherlock knew what he wanted to say.

"However, the door of 301 is closed, no one has ever entered at all, and the key is also in the hands of 201 Jiang Wentai, there is a problem."

Chen Yingjie finished supplementing what Lin Xi wanted to say, and Lin Xi nodded, that's what it meant.

"I'll explain that later."

Sherlock didn't explain directly, but turned to look out the window at the round of bright moons.

After waiting for a while, Sherlock thought to himself, Watson should come down too, and just thinking so, Watson grabbed the rope and hung above Sherlock.

"Sherlock, then!"

Watson struggled, but Sherlock looked up at him unhurriedly.

"Is that stable?"

Although it was a bit hard to hang in the air, because the length of the rope was just right, Watson's body was tilted across the air, leaning against the wall, very secure.

"It's okay, you can move your hands."

"If only I could move, then this."

Sherlock smiled and took out a dagger from his military backpack and handed it to Watson, who hesitated a little after taking it.

"What is this going to do?"

"Kill me."

Sherlock said something terrible that scared Watson and the audience behind him.

"Is this how the murderer kills?"

Chen Yingjie thought it was incredible.

"That's right."

Sherlock nodded, then proceeded to Watson.

"You can kill me according to what the wound of Jiang Wentai's corpse is."

Sherlock said very horrible things very calmly, which made Watson creepy, can't you say it another way?

"Okay."

Watson agreed, Sherlock thought a little more, and then continued to advise.

"When I say it's okay, you can do it again."

"Hmm."

After getting Watson's affirmative answer, Sherlock pushed Jiang Wentai's body away, and the blood stains formed a wide crimson ribbon on the wall, and the people behind him felt that this scene was particularly cautious, but Sherlock was as casual as changing the bucket of a water dispenser, worthy of being a detective.

Sherlock took a moment to push the body away, placed it on the ground, covered it entirely with a sheet, and then stood himself in front of the bright red wall, in front of the very center of the window.

Sherlock thought of an angle to admire the moon, and then he posed, bent over, and then lay down in front of the window, and raised his head slightly, looking at the moon, and he could not see Watson hanging less than thirty centimeters above his head.

「ok。」

Sherlock snapped his fingers and motioned to Watson, who got the signal and began to move.

He took the knife, thinking about how to kill him without being discovered by Sherlock, and was just about to reach out, but he retracted again, and tried it a few times, feeling that it was a little difficult to do, and suddenly the center of gravity was unbalanced, and the whole person hung upside down, and the drooping head coincided with Sherlock, and the four eyes were facing each other, only the distance between fingers.

"Ahh

Chen Yingjie screamed, and the others were also shocked, including Watson, who suddenly saw such a handsome face.

This scene is too terrifying, if you are not prepared, if you see it, you will definitely ...... Definitely pupil doubling.

"Alright, Watson, come down."

Sherlock wasn't surprised at all, although he suddenly made almost zero contact with Watson's face, but this was also something he had thought of beforehand.

"Okay, now I'm dead."
