Conan: Another Famous Detective

The next day, in the Yumiya Detective Agency, in Mengyu's room.

Mengyu clicked on the keyboard, staring at the computer screen in front of her with an extremely solemn expression.

Yu Gongming stood behind her, leaned over slightly, and gently pressed her shoulders. Even though he couldn't understand Meng Yu's operation, he still watched intently.

After a while, Mengyu stopped the operation.

On the screen interface, there is only an icon of a compressed file left at the end.

"Which procedure is this?" Yu Gongming asked.

"Yes." Mengyu nodded.

"Can it be opened?" Yu Gongming asked.

"It can only be opened." Mengyu replied.

Yu Gongming was stunned for a moment, then realized something and asked: "If it is opened, will there be any adverse consequences?"

"For the computer, there are no adverse consequences, but for the program itself, once you open it, it will self-destruct within a second."

"It seems that Itakura is really worried about [the well-being of mankind]. I thought he returned the check just because he was afraid of the organization's retaliation. It turns out that he had this meaning."

Yu Gongming suddenly frowned: "Within one second? Then we won't be able to understand the content at all?"

Mengyu sighed softly: ".I tried my best, but I can only delay this self-destruction to ten seconds. Therefore, we must record the content presented inside within ten seconds."

"Record within ten seconds..." Yu Gongming thought for a moment and said:

"You can only open the program and slide quickly to display more content. I will record the process with a camera and analyze the images later."

"This method is only theoretically feasible, but in fact, the content of this program is quite large. Even if you open it through a compressed package, it may take more than ten seconds to load the content."

"Is there no other way?" Yu Gongming asked reluctantly.

"At least not yet. Maybe I will come up with a new method after studying for a while." Mengyu replied.

"That's it..." A flash of hesitation flashed in Yu Gongming's eyes, but in the end, the hesitation turned into determination.

"Then completely destroy this program." He said calmly.

"Destroyed? Are you sure?" Mengyu asked in surprise.

"Yeah!" Yu Gongming gave a positive answer and further explained:

"Bellmode came last night, which means that we have been suspected by her. If the program is left in our hands, there is still a risk of her stealing it back."

"Compared to us, the organization has recruited many top programmers. They may have a way to crack this self-destruct command."

"In this way, we will lose most of the meaning of snatching the software."

"It's better to just destroy the program now. For software like this, which is developed on a year-by-year basis, the organization will definitely not be able to complete it again in a short time."

"In the final analysis, we are looking at the content of this program just to learn more about the organization's secrets, and there is more than one way to achieve this goal."

"So, destroy."

Mengyu turned to look at Yu Gongming.

Yu Gongming looked at him calmly.

Finally, she nodded slightly: "Okay, I'll listen to you."

Turning his head, Mengyu moved his mouse and clicked lightly on the compressed package.

The compressed package is opened.

A file directory was displayed in front of the two of them.

However, in the center above the directory, a countdown appeared.

10, 9, 8…

The number keeps jumping, and after a while, it returns to zero.

The directory interface suddenly closed, and the original location of the compressed package was empty.

After a few seconds, the compressed package appeared again on the computer, and then a progress bar appeared.

The progress bar quickly reached 100%, and then the compressed package disappeared again.

Then the above process is repeated. After more than ten times, the compressed package no longer appears.

Meng Yu gently leaned back on the chair and exhaled: "Okay, after so many data overwrites, even if it is restored again, I'm afraid there will only be a bunch of meaningless gibberish left."

"What's the principle?" Yu Gongming asked curiously.

Mengyu explained: "You should know that the underlying language of the computer is actually a binary number composed of 0 and 1. For example, the A we see may be 00 in the recognition of the computer, and the B we see , in computer recognition, it may be 01, and more complex ones, such as a certain Chinese character, may be 010001."

"And all programs are formed by combining countless 0s and 1s in a certain arrangement."

"And what we usually call deleting files is not actually deleting them completely. For example, the files you can see are actually equivalent to putting a sign on a warehouse."

"Deleting the file is equivalent to taking down the sign. Although you can no longer see it, the warehouse is still there."

"However, I remember checking the memory after deleting the photos, and the space has indeed increased. What's going on?" Akira Hanamiya asked.

"You can understand it as the so-called memory space, which is the capacity that you can import new data. When the old data is deleted, its priority will be weaker than the undeleted data and the newly imported data."

"Once new data is loaded at the location of the old data, the original data will be overwritten by the new data, and during this overwriting process, the sequence of 0s and 1s that make up the old data will be destroyed. .”

"That is, the original arrangement of 0101 may become 0000, or 0010. After this arrangement is visualized, the original content will naturally change."

"The more times it is overwritten, the more serious the damage will be. In the end, it will be completely impossible to restore the original program or software."

"That's it." Yu Gongming nodded suddenly.

"So, in the future, after I delete any important information, I will immediately import new data in the original location. This way, even if someone steals my computer or mobile phone, they will not be able to find that information,"

"Just leave this kind of thing to me." Meng Yu said with a smile.

"Then I'll have to work hard on you from now on~" Yu Gongming said, gently squeezing Mengyu's shoulders.

"Well~ a little further to the left..." Meng Yu narrowed her eyes in enjoyment.

"Oh, by the way, you should know what to say when Conan smells it, right?" Yu Gongming suddenly said.

"Well, I will tell him that Itakura has tampered with this program. Because of improper operation, the program has self-destructed."

"That guy will be very disappointed after hearing this, right?" Akira Hanomiya thought of Conan's frustrated look after hearing the news.

Meng Yu snorted softly: "I wonder who gave the self-destruct order just now?"

Yu Gongming chuckled: "You are the one who operates the computer! If you don't agree, can I still force you?"

"Tch~" Meng Yu turned around and glared at Yu Gongming angrily.

"Okay, okay, you must be tired after working all morning! Come on, let's go out to eat at noon today, I'll treat you!"

Meng Yu's eyes lit up: "That's pretty much it! But please give me a shoulder squeeze for ten minutes first!"

"Yes!" Yu Gongming said with a smile.
