Anyway, I don’t turn on the camera here and even the voice changer is turned on. I will definitely not admit my identity under such online chat.

"What's the matter?"

It was a little casual. When the communication was connected, Kuroyuki Kuaido asked this question.

"Can you tell me in detail why you ask Gao Yuan that he is indeed a Chinese?"

However, what Kuroyuki Kaito didn't expect was that what came from the headphones was not Koizumi Hongko's voice, but the voice of the girl who was next to Koizumi Hongko and did not appear in the camera:

"Why do you suddenly ask about this kind of thing just based on what he said about high school teachers?"

At this moment, the other party's screen camera turned off and only sound could be heard.

In response to this, listening to the other party's urgent inquiry tone, Hei Yu Kaito was a little surprised-

However, the other party was with Akiko Koizumi, and Gao Yuan asked Akiko Koizumi to take good care of her at that time, so what is the relationship between the owner of this voice and Gao Yuan?

And from her tone, she seemed to care about this answer very much...

For a moment, thinking about Gao Yuan's ambiguous attitude when facing his question, Hei Yu Kaito couldn't help but feel that if he told her what he knew, it might be a big problem for Gao Yuan. So Hei Yu Kaito couldn't help but explain:

"Miss, think about Gao Yuan's current age, think about his age, when he was in high school, what age was a high school physics teacher who was about to retire? Then convert the age of the high school teacher's birth, and think about why the foreign language he learned when the high school teacher was studying was Russian?"

In response to this, when Hei Yu Kaito finished speaking, the person behind the computer communication interface was silent for a moment, and then said with some surprise:

"you mean……"

"Not to mention that in that era, even now, foreign language education in high schools in China has always been mainly English. Even when we get to college, the second foreign language has always been the most elective students of French or German, and Chinese has only become popular in recent decades.

"It can be seen from this that it would be rare to find a foreign student in China who used Russian as a foreign language? And such people finally taught physics in high school. It can be seen that his major was not language, and Russian should be just his foreign language course.

"So, due to the times, there were very few such people in China, but in that country, it was very common!

"From this, I judged that Gao Yuan was in high school in that country!"

"But, he might have gone abroad in high school?"

Faced with the analysis of Black Feather Prodigal, the girl still raised a possibility at the other end of the communication interface.

In response to this, Kuroyuki Kaito smiled and expressed his other basis for judgment:

"Of course not only that. Before that, when I heard him mention the difference between the Chinese characters "left" and "right", he actually said the Chinese characters "gong" and "mouth" rather than the pseudonym "丨" and "中". If his first mother tongue was Japanese, wouldn't his reaction be strange?"

As he said this, Heiyu Kaito finally added:

"Of course, the above are just my personal guesses. I don't know Gao Yuan's past."

"Yes...I understand, thank you."

In this way, when the girl who was facing each other in the communication interface thanked her in this way, she hung up the communication.

In response to this, Heiyu Kaito couldn't help but smile—

Gao Yuan, don’t blame me, it’s your own flaw!

...

And for this, the person who communicates with Kuroyuki is naturally Xiao Ai who is with Koizumi Hongko.

After Xiao Ai learned about the other party's specific analysis through the communication just now, she couldn't help but feel that her understanding of Gao Yuan was far from enough.

His past, in the end...
