At this time, when he opened the book "A Brief History of Time", Luo Fei did not find anything entrained from the book.

Could it be that the location of the "blueprints" has nothing to do with the book? After Luo Fei quickly rummaged through the book to see if there were any entrained items in the book, he looked through the pages again with some unwillingness.

This time he slowed down a lot of the page, and when he reached page 12, he finally noticed that the page number "12" had been drawn in a small circle with a black carbon pen.

This discovery gave Luo Fei renewed hope that the book "hides the secret of the blueprint".

After seeing that there was no text on the page except for the page number, he gently folded a corner of the page to mark it, and continued to turn the rest of the pages back!

Soon on page 28, Luo Fei saw that the page number of the page was also circled in black.

This is followed by pages 39, 47, 51, 64, 73, 86, 95.

These page numbers are marked with small circles in black carbon pen.

After that, no page numbers are marked. Obviously, the whereabouts of the "blueprint" are likely to have something to do with these 9 numbers!

"Judging by the numbers shown on these pages, they are not duplicated, whether they are tens or single digits!" Luo Fei, whose character's intelligence value was already very high, discovered a little bit almost immediately.

But if it's just numbers, the simplest thing to think is, these numbers are probably the passwords to some "safe" or "electronic file" that needs to be opened with a password! Luo Fei thought of this, because he didn't find the safe in the room, so he immediately focused his eyes on the computer on the desk.

Because after entering the house, Luo Fei thought that the "design drawing" would definitely not be placed on the computer desktop without any confidentiality, so he started with the books on the bookshelf.

At this time, because he got the number of "suspected password", he sat on the chair in front of the computer and pressed the boot button of the computer, and waited for the computer screen to light up with a little nervousness, hoping to find the design drawing file with the password from the computer.

However, when the boot of the computer was successfully completed, Luo Fei saw a folder with the name of "8975 Core Design Drawing", which was completely displayed on the desktop of the computer without concealment!

"How can it be so obvious?" Surprised, he tried to open the folder with his mouse.

At the moment when the folder was clicked, a very strange thought suddenly appeared in Luo Fei's mind:

That's - don't open this folder at one point, and then the files in it don't have passwords, it's the kind that can be opened and viewed just by clicking!

And the reason why Luo Fei had this idea is because if this situation really occurs, not only does it mean that his previous behavior of finding a "breakthrough point" from the bookshelf is really stupid, but even the behavior of asking him to ask for a "design drawing" before 8975 is completely "the drunkard's intention is not to drink", and there is a high probability that 8975 has already obtained the design drawing!

Fortunately, as soon as the folder was clicked, a prompt box popping up requiring you to enter a password.

And below the prompt box, it is also very eye-catching:

If you enter your password incorrectly 3 times in a day, the folder will not be opened on that day.

"Thankfully, my hard work on the bookshelf to find clues was not in vain." Luo Fei laughed when he thought of this.

Because of the situation in front of him, it was obvious that even if he turned on the computer first after entering the room, he still needed to find a way to find a way to read the books on the shelf.

"Looking at the length of this password input field, it should be able to accommodate a lot of numbers."

Although with Luo Fei's current memory, he can fully remember the "page numbers" he saw before, he still took out a black carbon pen from the pen holder on the table, opened the first page of "A Brief History of Time", and wrote those "page numbers" in the blank space on them one by one, and carefully studied them.

If there were 3 chances, Luo Fei decided to try 289714365 first.

Because these numbers may symbolize that page numbers such as 12 and 28 indicate that the first digit is 2, the second digit is 8, and so on.

However, after Luo Fei entered these 9 digits, he found that there was still about 4 digits of the password in the password input field!

If the free password is 9 digits, then Luo Fei can directly enter all the page numbers into it.

But now there are only 4 digits left in the position, which really makes Luo Fei have no clue for a while.

"Maybe I'm thinking complicated, the password doesn't have to fill the entire input box!" Since in real life, this kind of situation where you don't need to lose all of them is not uncommon, so Luo Fei decided to press the word "OK" next to the input box to try first, anyway, even if it fails, there will be two chances to try.

However, it is not so simple. After pressing OK, the folder is not opened!

The annotation below the tooltip immediately became:

You have 2 wrong chances left today and can't open the folder that day after running out

"It looks like it's really missing a 4-digit password!" Luo Fei looked at the numbers he had written on the first page of A Brief History of Time and began to consider whether they were any other combination of them.

"Can't you remember the password combination?" Since Luo Fei did not specifically ask Wang Ming to avoid it when he entered the password, Wang Ming, who had been standing beside him and watching this, asked with concern after seeing that the folder had not been opened.

"Yes, maybe I've just recovered and don't quite remember how the password came out of these numbers." Luo Fei admitted to Wang Ming without concealment.

And he had no clue for the time being, and he also took the initiative to ask Wang Ming to participate, and told him how he had just obtained the password number from 9 page numbers, and asked him to help think about whether there were other combinations!

"If you want me to try, unless you try the ten digits of the page number again, but the ten digits are also nine digits, and if the password is really 13 digits, it will be another wasted opportunity!" Wang Ming thought for a while, and then simply said his opinion.

"Try ten figures?" Luo Fei felt that the probability that the password was 9 pages and 10 digits was really not high.

He picked up the "bookmark" he had found earlier, and slowly read the two sentences again.

When he read the last four words of "too little time", a flash of inspiration suddenly flashed in his mind!

Because when Wang Ming once said his thoughts on these two sentences, he thought that the core meaning of the words was concentrated in these four words.

"That's the SJTS?" Luo Fei thought that when he was working in the real world, he also encountered some confidential materials that required a letter + number password, which was more difficult to be deciphered by others than a pure numeric password!

However, when he was about to try it with these four letters, another problem appeared in front of Luo Fei.

Because even if "sjts" is the correct answer to the remaining four digits of the password, should you enter the letters or numbers first when entering the password?
