I'm making soy sauce in the detective world

"Yeah." Xiaolan nodded in agreement, "I hope I can catch the murderer soon."

After the two had finished speaking, Shancun Cao said, "However, in the deceased's mouth, we did not find the trace left by the rope."

"Well..." Yuanzi was lost in thought.

It should leave traces, right?

How could it not be found?

Is her reasoning wrong?

It shouldn't.

While Yuanzi was still thinking, Conan took out the handkerchief he used to wipe his nose from his pocket and gestured to Yuanzi.

Yuanzi happened to see Conan's actions, and suddenly figured it out:

"It's a handkerchief!"

"Didn't it mean that a handkerchief dipped in curry fell beside the body?"

"Yes." Shancun Cao nodded and asked puzzledly, "Does that handkerchief have anything to do with what you just said?"

"Of course there is." Uncle Maori glanced at the mountain village fuck that he hadn't figured out so clearly, and explained to him.

"Just wrap the rope with a handkerchief and let Mr. Yan Fu bite in his mouth."

"If you do this, there will be no traces of the rope left in your mouth."

Seeing everyone understood what he meant, Conan nodded repeatedly.

It seems that this method is still feasible.

Although there were some small errors in the process, the train to the truth was finally back on track.

"It turns out that it's such a thing." The mountain village made a look of knowledge.

"However, when the body was found, my hands were not tied." Uncle Maori questioned, "In this case..."

"As long as you grab the rope with your free hands, you can cry out for help."

Although the corpse's hands and wrists were found to be tied up, the hands were not tied up when the corpse was found.

And Akashi Hiroto also said before that his father has the habit of tying rubber bands on his hands.

Many rubber bands were also found under the pillows in the bedroom.

This method is indeed feasible, but if it does not solve this problem, it will not work.

"Furthermore, the light in that bedroom was still on an hour and a half ago, but it was turned off when the body was found." Uncle Maori questioned again.

"During that time, no one had been to that room, so how should I turn off the light? Mr. Yan Fu couldn't have turned it off himself, right?"

He explained all the loopholes in this method.

Only by filling these loopholes can this modus operandi be established.

"That's right." Yamamura Cao also felt a little puzzled. "Could it be that the murderer in this case was someone outside?"

What is strange is that there were no signs of intrusion by outsiders.

No matter on the second floor or the first floor, all the windows and doors in the whole house showed no signs of being forcibly opened.

The police did not find other people's fingerprints on the edge of the window or on the door. There may be fingerprints, but they did not find it.

At least for now, they have not found any clues to prove that outsiders broke in.

Therefore, the possibility of outsiders entering the house to commit crimes is very small.

Looking at the people who were thinking about it, Akashi Hiroshi secretly relieved in his heart.

Fortunately, he thought of that institution.

As long as the mechanism is not discovered, he can use other reasons to get past everything.

But at this moment, Conan suddenly climbed onto the table, stretched out his hand, and pulled the light rope.

"Patter!"

The lights dimmed a bit and Akashi Hiroto became a little nervous.

This voice sounded like the footsteps of a "hunter" in his ears.

"Conan, you can't be so messy!" Xiaolan didn't know Conan's thoughts, and hurriedly stopped.

After seeing Conan's actions, Uncle Maori paused, as if thinking of something.

Then, instead of stopping, Conan pulled the light rope twice.

"Pap! Pap!"

The light dimmed again, and then disappeared directly, and the whole room was suddenly enveloped in darkness.

"Patter!"

There was another sound, and the lights turned on again.

Sitting back in his seat, Guangyou tore off the plastic packaging bag of Dorayaki that he brought back when he pulled the light cord, and took a bite.

On the side, Xiao Ai helped Guangyou pour the water, and looked at the book that she had just pulled out from the shelf.

One of them came out occasionally to remind and correct the direction of reasoning, and the other didn't want to get involved at all.

"Unfortunately, I finally went out for a vacation, and I was soaked again."

"Fortunately, this case should be over soon."

As if taking Dorayaki as the Akashi Hiroto who ruined their vacation, Kosuke took a big bite.

"Conan, how can you play a prank like this?" Xiao Lan quickly got up and took Conan off the table.

"I know." Uncle Maori wanted to understand, he knew what method to use to fill the two loopholes.

"Tie both hands with the cord on the electric light, and then tie a bow."

"In this case, when Mr. Yan Fu runs out of strength, he will loosen the rope in his mouth and his body will fall."

"While being hung up, it's like pulling down the light rope, the light will naturally go out and the bow will loosen."

"So, when we find the body, it will become that state."

"So the thin marks on Mr. Yanfu's hands and wrists are really the marks left when he was tied?" Shancun Cao continued.

"If nothing happens, it should be like this." Uncle Maori nodded and said.

"But lights like this have three levels of brightness." Xiaolan asked suspiciously, "Just now Conan pulled the cord three times before the light went out."

The lights in this room all have three levels of brightness:

The first gear, which is the brightest gear, is all on except for the warm light in the middle.

In the second gear, except for the warm light, the outermost lamp will not light up.

In the third gear, only the warm light in the middle is on.

This kind of light does not have a quick shift button, only a light cord is used to control it.

The third level of brightness means that if you want to turn off the light from the brightest first level, you have to pull it three times.

But it's not that there is no way to do it all at once.

The method is also very simple.

Afterwards, while eating dorayaki, Guangyou explained to Xiaolan and the others who had not figured it out:

"Actually, as long as you loosen the bulb of the warm light in the middle, and adjust the brightness to the second gear, you can pull it once and the light will go out."

Not to mention, this brand of Dorayaki tastes good.

No wonder Fat Blue likes eating this thing.

Realizing that his thoughts were a bit off-track, Guangyou shook his head and turned his gaze back to Uncle Maori.

"Yes, that's what I meant." Uncle Maori nodded in agreement.

After staring at the one on the light rope, he knew that the knot was very complicated. After observing for a while, the mountain village Cao asked suspiciously:

"It does make it possible for people to be absent and to turn off the lights."

"But can this knot be untied?"

"Huh? Why untie it?" Uncle Maori asked puzzledly.

"Mr. Maori, look." Shancun Cao said, pointing at the lamp rope.

"If you want to tie Mr. Yan Fu's hands, you shouldn't be able to tie them when the light is connected."

"So, I think this knot must have been untied by the murderer once, and then tied up again."

"Well, it makes sense." Uncle Maori nodded in agreement.

"But, it seems that this knot is very complicated." Shancun Cao leaned close to the lamp rope and carefully observed the knot on it.

After he finished speaking, the others also turned their gazes to the lamp rope that was specially extended.
