In the investigation that followed, Conan showed his ability to reason.

Tiny blood stains were found on the file bag, and then the quadrangular shape on the elevator.

Clues, too, become circles, forks, triangles, and quadrangulations.

Therefore, excluding the alibi, there are still 31 people left. However, such a situation is not of much help now.

And because we don't know the connection between them, we can't substitute these symbols into the four names.

Subsequently, Yuanzi and the others took the photocopied list of only 31 suspects after removing the people with proof of presence, and began to discuss what the names of the circles, crosses, and triangles would become when combined.

As for Officer Twilight, he asked Officer Takagi to go to the eighth to eleventh floors where the company is located to help Chiba start the investigation. Hopefully some clues can be found.

During this period, Xiaolan left the meeting under the pretext of going to the toilet. It seems that he is very concerned about the meaning of X mentioned during the discussion.

As for Conan, he didn't care about Xiaobai and Xiaoai at all and started his own search.

"Is it really good to go on like this?" Xiao Ai sipped his drink as he looked at Conan, who had been running around the scene not far away.

"Aha, I'm feeling a little tired. Why don't you give him a hint?" said Xiaobai, yawning.

"I've been saying that for a long time. Xiao Wai shrugged his shoulders and said.

"By the way, do you already know who the murderer is?" Then, Xiao Ai looked at Xiao Bai and asked.

"Well, judging from the clues obtained, the murderer is a 4-character name, and the lower part of the name is similar to a circle, a fork, and a triangle from the name. Xiaobai said.

"Why the next part?" asked Xiao Ai uncertainly.

"The documents in the bag were taken away, and all that was left on the bag were circles, forks, triangles, and quadrangles in the elevator. 」

"Judging by the bloodstains, the quadrangular should be the first, then the circle, the fork, the triangle. 」

"A quadrangular can be a shortened name. And what really matters is the circle, the fork, the triangle. 」

"??" Xiao Ai seemed to throw the question of thinking directly to Xiao Bai, knowing that the answer was why bother thinking about it.

"Imagine if the other party wrote down their name, and then because of the power outage at the time, they didn't know if it was written on the document bag or the document. Xiao Bai smiled and looked at Xiao Ai.

"You mean...... Xiao Ai is not stupid, after hearing Xiao Bai's explanation, he has an answer.

"In fact, many times, the death message is very simple to answer, but everyone complicates it and thinks it is not that simple. 」

"Well, that's true. Xiao Ai nodded in agreement.

"Looks like Judy-sensei has found out too. Then, after Conan was caught by the police again and chased away in the name of troublemaker, Judy smiled at what Conan was saying.

"For example, the defense headquarters of the United States of America is generally called the Pentagon. As soon as Bai and Xiao Ai walked in, they heard Judy talking to Conan.

"That's because the building of the Defense Headquarters is pentagonal, which means Pentagon. 」

"In the U.S., you might use a name that doesn't have the same meaning. 」

"Actually, it's more than that. For example, White· House means white house and refers to the presidential palace. As for the oval office, it is called the oval office, which is the president's office. In addition, bereau represents meaning of the bureau. 」

"The most famous example is...... FBI。 At this point, Judy paused for a moment. At the same time, the FBI is also an English sermon.

"FBI?" Although they hadn't come to the front yet, Judy's story was still heard by Bai and Ai. At the same time, Xiao Ai frowned when he heard this, and then looked at Xiao Bai.

"Please enter the game, you have no intention, but you are in. Xiaobai looked at Conan not far away and said these garbled words.

"Have they all noticed me?" Remembering the recent events, and then stringing them together, Xiao Ai had an answer.

"Well, both sides are already eyeing you. Xiaobai laughed.

"We?" Is there anyone but ourselves......?

"Well, that's exactly what you think. As if he knew what he was thinking, Xiaobai said.

"Exactly, when?" Xiao Ai lowered her head, her eyes misty.

"It doesn't matter when, this time will come eventually. Xiao Bai's right hand held Xiao Ai's left and right. Then, domineeringly, he stretched out Xiao Wai's hand, and then held it.

Feel the temperature of the palm of your hand and look at Xiaobai with a fox smile on her face.

"Even after that, no matter what you decide, I will support you. Xiao Bai's face slowly approached, and then whispered in Xiao Ai's ear.

"It seems that they won't notice us for a while, go buy something, I guess the case will be solved when we get back." Looking at Conan with a confident smile not far away, Xiaobai took Xiao Ai's hand, left the crowd, and walked towards the supermarket in the mall.

......

"What kind of identity are you?" Although he blushed a little when he was held by Xiaobai. However, the thoughts in my heart are always unstoppable to think and ask.

"The organization, the FBI, and the ......"

"The man who grew up with you......

"What's the relationship?"

"There are really too many things I don't know......

"I want to know, I want to know, I want to know more......

"But the more I learned, the more I realized that I didn't know the whole story. Or never really understood......

......

"Well, let go. Although he was choosing what he needed, everyone who passed by would be chuckling and passing by, and Xiao Ai obviously knew what the other party was laughing at.

"What does it matter if you are seen like this? Xiao Bai raised his clenched hand and looked at Xiao Wai.

"Yes, why care about other people's opinions?" Listening to Xiao Bai's answer, Xiao Wai said in his heart.

"What do you want for breakfast tomorrow?" asked Xiaobai as he chosen.

"The Doctor can't eat fried food anymore. Xiao Ai habitually responded.

"Well, in that case...... Let's make pasta. Xiao Bai said as he led Xiao Ai towards the noodle area.

......

"It's a good feeling. Looking at Xiao Bai walking in front of him, Xiao Wai smiled......
