Super Time Detective

Ye Huairui quickly noticed that, excluding the title, this "Lost Notice" has a total of nine lines, and if the punctuation marks and the last two lines of contact information are not counted, which belong to the "text" part, each line also happens to be nine lines. words.

"Haha."

Ye Huairui smiled lightly.

The prompt is so obvious, it is not difficult to guess.

Nine lines and nine Chinese characters clearly correspond to the nine numbers from 1 to 9, so the "pigeon2" used for decoding should naturally be the following two strings of telephone and paging numbers.

In view of the fact that the decoding method demonstrated to Yin Jiaming by the second brother He was the most basic password marking the number of rows and columns, Ye Huairui felt that He Zhicong would definitely choose the same method this time.

In other words, the string of phone numbers and paging numbers must contain two pieces of information, "row" and "column".

That being the case, according to the simplest and least error-prone logic, as long as two adjacent numbers are combined, the first represents "row" and the second represents "column", no you can easily Marked a word?

Just do it, Ye Huairui picked up the pen and wrote down the decoded result on the paper.

"Contact number: 235538" is the third character on the second line, the fifth character on the fifth line, and the eighth character on the third line, which are "jie", "tai" and "ping".

"'Jie Taiping'?"

Ye Huairui whispered softly:

"It looks... like a person's name."

Next is the paging number "1251044048".

According to the previous thinking, "12" is the second character in the first line, that is, "Zuo", and "51" is the first character in the fifth line, that is, "Lun"—"Zolun".

"what!"

Ye Huairui called out softly.

Although he hasn't been back to Jincheng for a long time, as a forensic doctor, he often has to go out to work, and he has been to quite a few places.

He immediately realized that the so-called "Zolun" should refer to "Zolun Street" - it is located on the southeast side of Jincheng, and that area is an old city with some history.

The next four numbers "0440" are a little tricky, because the concept of "the fourth character on the zeroth line" and "the zeroth character on the fourth line" does not exist in "The Missing Person Notice".

In 82, Jincheng’s fixed-line telephone number had six digits, while the pager number had dozens or eleven digits more. The first three digits were the operator’s code, and the last seven or eight digits were the pager code.

He Zhicong published this "Missing Person Notice" in the newspaper in order to pass the information on to his younger brother quietly. In this case, he must not arouse suspicion, and the number must be designed to be the same as the real one.

In this way, Ye Huairui speculates that "0" may be a meaningless number filled in to make the number look more ordinary and inconspicuous-this method has a proper term in cryptography called "invalid number". decoration", or "invalid embellishment".

Ye Huairui knows that He Zhicong is a historian, and the subject is also related to the "Pigeon Telegraph" during World War II, so someone with relevant knowledge must follow the basic rules when setting up "pigeon2".

In addition, his "Pigeon Telegram" was written for that idiot Yin Jiaming, so it's too complicated to kill his brother?

Therefore, Ye Huairui thinks that these two abrupt "0"s are likely to be pure "invalid decorations". If they are removed, there will be another set of coordinates - "44".

The fourth character in the fourth line is "eight".

In the end, there is only one "48", the eighth word in the fourth line, "number".

Then, looking at it together, it is an address: No. 8 Zuolun (Street).

Ye Huairui turned on the phone and entered this address.

It's a pity that the area of ​​Zuolun Street has been renovated almost from the beginning to the end in these years, and the current "No. 8 Zolun Street" is a [-]-story office building.

But now the message He Zhicong left to Yin Jiaming is obvious.

This man named Xie Taiping was probably the guy who wrote the note, and he lived at No. 8 Zuolun Street.

Ye Huairui decided to find out the identity of this man named "Xie Taiping" first.

Since the person was found by He Zhicong, a professor at Jincheng University, Ye Huairui felt that Xie Taiping was probably related to Jincheng University.

After thinking about it, he took out his cell phone and called Tan Xi.

At that time, Tan Xi was nestling in his laboratory, taking pictures of his beloved slime molds with a micro-focus lens.

He answered Ye Huairui's call, "Is there anything wrong?"

Ye Huairui told Tan Xi that he wanted to enter their school history room and look through old yearbooks from decades ago.

"what?!"

Because this request was so peculiar, Comrade Ah Jun thought he had heard it wrong.

"You want to enter our school history room and look through the school history of the 80s?"

"Well, not necessarily."

Ye Huairui said with a smile:

"Maybe it will take a few more years to go forward."

Tan Xi: "..."

For a moment, he felt that Ye Huairui was teasing him, but his friend's tone on the phone was very serious, not like joking at all, "Why did you do this?"

Ye Huairui didn't want to hide from his friend, and said truthfully, "Because this is related to an old case I'm investigating."

Tan Xi was at a loss for words.

After a while, he sighed: "Okay, then I'll figure out a way."

For a science geek who lives in the laboratory every day and almost never participates in group activities, even if he just helps his friends into the school history room, he has already consumed a lot of social energy points.

Fortunately, Tan Xi still completed the task with difficulty.

An hour later, Ye Huairui, Tan Xi, and his assistant Ouyang Tingting, whom he specially called to help, stood in front of the yearbook display rack in the History Office of Jincheng University.

"I only have one name, 'Xie Taiping', 'Xie' from 'Xiechi' in Shaanxi, 'Taiping' from 'Taiping Prosperity'."

Ye Huairui said to the other two, "As for age and gender, whether it is a student or a teacher, I don't know anything."

Tan Xi and Ouyang Tingting: "..."

The two were silent for a while, then they raised their heads together by coincidence, looked at the yearbooks that were packed to the brim on the bookshelf, each of which was thick enough to kill people, and shuddered inexplicably.

"What year?"

Tan Xi looked at his friend tangled, and silently felt sorry for the slime mold babies in his incubator—when he returned, those cute babies would definitely be starving, "You have to know the exact year, right? "

"It's really hard to say which year it is."

Ye Huairui spread his hands honestly:

"Anyway, it must have been 82 years ago."

In fact, Ye Huairui doesn't even know whether the other party is a student or a teacher, but as long as Xie Taiping has been active in Jincheng University, there is a high chance that he will leave traces in the yearbook, even if he is just an ordinary graduate of a certain major in a certain school year born.

What's more, the second brother He was just an ordinary university professor back then, and the information channels he could get access to were not at the same level as the police.

Even the clues that he can find must not be too secret channels - Ye Huairui thinks that the yearbook should be a good choice.

Ouyang Tingting knew that Forensic Ye was investigating the Jincheng robbery recently, and she was not surprised by the number "82 years". Comrade Ah Jun was puzzled by Monk Zhanger, and had no idea what his friend was doing.

But he is a character who does more than talks.

Now that she agreed to help, Tan Xi didn't bother to ask any more questions, so she just did what she said. She scanned the shelf and pulled out the book with the number "1982".

The three of them each moved two or three yearbooks, carried them to the reading table in the corner, and began to dig through them.

Even if the yearbook back then was not as thick as the five or six hundred pages it is now, at least it started with two hundred pages, and it was very laborious to flip through.

The three of them were afraid of missing an inconspicuous name, so they read very carefully, and the speed of browsing was not fast.

Finally, after four or ten minutes, Ouyang Tingting suddenly called out:

"I found him!"

She pushed the yearbook in her hand towards the middle of the reading table:

"Here, Xie Taiping! It's a teacher!"

Ye Huairui and Tan Xi immediately moved over when they heard the words.

What Ouyang Tingting is looking through is the yearbook of 1977. "Xie Taiping" appears on a group photo of engineering graduates of the 77th grade. Below is the name of each person in the photo, followed by "Associate Professor" this title.

The accuracy of the color photos 39 years ago is very touching, and when reprinted in the yearbook, you can barely see the general appearance.

Xie Taiping in the photo looks like a tall and thin middle-aged man, about the age of forty and a half, with an ordinary appearance and a serious expression. A tight line.

"It's easy to know it's a teacher."

Ye Huairui smiled and encouraged Ouyang Tingting and Tan Xi, "Come on, let's look through and see if there are any more clues!"

…………

……

As the saying goes, hard work pays off, and the three really found more traces of "Xie Taiping".

In the yearbook of 1976, Xie Taiping, as a special designer, participated in the planning and design of the sewage pipeline renovation project in the lower ring and Xiwan areas of Jincheng that year.

The sewage pipes used by the robbers to invade the Fu Shou Branch of Dah Sing Bank are located in the Xiahuan District!

Next, in the 1979 yearbook, Xie Taiping's name appeared again.

But this time, he is no longer the outstanding designer that Jincheng University is proud of, but was expelled from Jincheng University for commercial fraud.

"I see……"

Now Ye Huairui has been able to confirm why Yin Jiaming and his second brother can confirm that this Xie Taiping must have participated in the robbery, or simply was a part of the robbers - because this is too suspicious!

And if it was in 1982, not long before Xie Taiping left school, He Zhicong should still be able to find the documents he left in the school.Comparing Xie Taiping's handwriting with the handwriting on the note, there is no possibility of misidentification.
