Stay away from Conan.

"When investigating the cause of death of the first minister, I excluded a subordinate from serving His Highness Yakov, hoping to find clues from his daily life. And just a few days ago, my subordinate found this in the trash can in His Highness's room..."

After the attendant took out the rope, he began to talk in English about what he had done for the investigation. The rope in his hand was displayed in front of everyone. Just one look at it showed that there was indeed something wrong with the rope.

After all, there is a knot tied on this rope at certain intervals, and the distance between each knot is different.

So, regarding this rope, Maori Kogoro asked in confusion:

"what is this?"

But for Conan and Gao Yuan, this does not require much explanation, because the knots tied on the rope at different intervals are obviously a form of encryption.

"Before the second minister died in vain, several more ropes of this kind were found in His Highness's room."

Unable to understand Japanese, the princess's attendant continued to explain the situation, explaining the evidence of the connection between the rope and the murder of the minister and the prince.

As for the communication difficulties between the attendant and Maori Kogoro, the princess made her guess after the attendant finished explaining the situation and said:

"I suspect that my uncle used this liaison killer to assassinate the two ministers."

After hearing this, Maori Kogoro took the rope from the attendant's hand and looked at it impatiently. He felt that it was just an ordinary rope and it was a bit far-fetched to link it with the minister's death. He said:

"You're just using this kind of waste rope? And if you're contacting a killer, you wouldn't use something that you would just throw in the trash, right?"

Maori Kogoro made such a guess, but seeing the princess' serious look, he calmed down and said:

"Okay, I understand. I will investigate. Anyway, since I, the famous detective Maori Kogoro, have been invited here, the princess's safety will be in my hands. I promise that everything will be fine!"

In this way, Kogoro Mori made such a promise to Princess Raduna.

At the same time, Gao Yuan saw this and said:

"We will try our best."

Just like that, after getting responses from Takato and Maori Kogoro, Princess Raduna couldn't help but say:

"Then I'll trouble you."

So, after meeting with the princess and leaving the room where the princess was receiving everyone, Maori Kogoro walked on the road holding the rope he had received from the attendant. He looked around and felt completely bored. After finding a trash can on the side of the road, he casually rolled the rope into a ball, and then flicked his finger and threw the rope ball directly into the trash can.

"Well, it's just the right amount!"

Maori Kogoro was very satisfied with his action of throwing the rope ball directly into the trash can, and then he said impatiently about the rope:

"Who would throw an important contact signal directly into the trash can? What a fuss! Using something like this as evidence!"

Then, Maori Kogoro said to Conan:

"I'll go check around. Don't run around this time, little brat!"

After saying that, Kogoro Mori prepared to investigate alone.

Conan, who stayed at the scene, was shocked when he saw Maori Kogoro throw away such an important clue. After Maori Kogoro left, he ran to the trash can and quickly picked up the rope thrown into the trash can, saying:

"I can't believe that such a rare clue was lost! What is uncle doing?"

So, after Conan picked up the rope, he unfolded it and checked it. After making sure that the knot on it was still intact, Conan breathed a sigh of relief.

Then, Conan looked at Gao Yuan and couldn't help saying:

"What do you think, Mr. Akechi? This rope..." "It should be a password."

In response to Conan's question, Gao Yuan naturally said:

only……

Gao Yuan was confused and did not continue to speak, while Xiao Ai asked:

"So how do we interpret this?"

"It takes a special deciphering ruler to decipher this kind of code!"

Conan explained this, and then explained:

"This should be the 'Aeneas knot' used in ancient Greece. Different letters are expressed by different intervals between each knot. This interval needs to be agreed in advance, so it is impossible to decipher this code without knowing it."

Speaking of this, Conan couldn't help but think:

"If Prince Yakov really passed the message to the assassin in this way, then maybe the assassin who sneaked into this airship is carrying this interpretation ruler..."

"But, in order to build momentum for this flight, the country of Panasukla invited many celebrities to board this airship. How can we check this?"

Gao Yuan roughly understood Conan's idea, and explained the existing problem like this:

There are not only members of the Panasukra delegation on this ship, but also many celebrities.

Moreover, as if to reduce the impact of the assassination two days ago and to prevent the invited celebrities from being frightened and giving up boarding the ship, Panasonic did not invite the Japanese police to board the ship to protect safety. It only checked the people boarding the ship with metal detectors before boarding to ensure that no one would bring weapons on board.

However, if it was a ruler used to decipher codes, it would obviously not be counted among the items checked, so it is completely uncertain whether anyone would bring such a thing on board.

Conan also understood the dilemma, but still said:

"There is no other idea at the moment, I can only try to investigate first..."

"Then for the sake of efficiency, let's just investigate separately. If there is any situation, contact us immediately and don't act rashly."

So, after Gao Yuan gave a warning, the two sides began to act separately.

And just like that, when Conan left, facing the situation where only Ai was left with him, Gao Yuan finally spoke:

"Now... we are the only ones left. Huiyuan, what do you want to say? Ever since you met the princess just now, I felt that something was wrong with you."

At this moment, facing Xiao Ai, Gao Yuan had already discovered that something was not right with Xiao Ai, but because there were outsiders present at the time, he did not say it out loud.

After all, Gao Yuan and Xiao Ai knew in advance that the organization might be involved. Maybe Xiao Ai discovered some clues about the organization's involvement.

In response to Gao Yuan's question, Xiao Ai did not deny it, but replied seriously:

"The backer behind Yukar Company is the organization!" (End of this chapter)
