[When Miss Xia Huang saw this letter, Zai Xia had already left Wolan City, please forgive me for not saying goodbye, and give this villa to Miss Xia Huang as an atonement. - by Liu Han. 】

When Mo Ling saw this note, it was already the next morning, and the note was placed on the coffee table in the hall on the first floor and pressed by the villa's master control magnetic card.

"Is there still no real trust?" Mo Ling pinched the magnetic card in his hand and tilted his head, although it is a good thing that cannot be refused to be white, but how can this development have the illusion of being fostered?

After resetting the access code of the villa, Mo Ling walked out of the villa, and the oncoming breeze slapped on her face, and there was morning moisture.

Looking at the map on his phone, Mo Ling came to the lane closest to the villa. Before this, Mo Ling had already informed Bai Ye of his current situation.

Since the time was just over six o'clock, and there was a villa area near the mountain, so that there were basically no vehicles on the driveway, Mo Ling had to sit on the big rock on the side of the road in a bored daze.

The faint morning light fell on Mo Ling's face, the morning breeze stirred her hair, and Mo Ling was thinking about a dream she had last night.

It may be a bit inappropriate to call it a dream, because that dream is something that actually happened, and in the dream she made a pact with someone—

The man gave her three years of freedom, during which the man would not be by her side. But after three years, she had to respond to that person's feelings.

Mo Ling couldn't remember the face of the person in the dream, and she couldn't even recall the voice, but she was sure that the person in the dream was King Yu.

For a long time, Mo Ling had very little memory of King Yu in his mind, except for knowing that his surname was Yu and his strength and IQ were extremely high, there was no more information.

It is precisely for this reason that Mo Ling has been in passive resistance to King Yu, but this situation is about to come to an end after last night's conversation......

"Is this young lady waiting for a taxi?" A voice suddenly came to mind in his ears, interrupting Mo Ling's thoughts.

Mo Ling looked up, and a handsome face poked out of the taxi window, Mo Ling felt that this face was a little familiar for some reason.

Just as Mo Ling was thinking about where he had seen the other party, the young man suddenly pointed at Mo Ling and exclaimed, "You are the girl who doesn't pay attention to hygiene and litters in the wild." ”

Mo Ling looked at the other party with wide eyes, she didn't remember that she had done such a tasteless thing, could it be that Xia Huang of her predecessor did it?

"When I was in Wuxian, Miss took my car, and when we came to Wolan City, we can still meet, which has to be said to be a kind of fate!" The young driver said enthusiastically.

Wu County?

Mo Ling finally had some impressions in his mind, and the other party seemed to be the driver of the taxi when he went to the Lingshan Cemetery before returning to Wolan City.

……

The car started slowly, and the young man tilted his head and glanced at Mo Ling in the passenger seat, and asked with some confusion: "Isn't this young lady curious about why I appeared in Wolan City?" ”

"Not interested." Mo Ling sat on his knees and poked his fingers at his phone, and replied casually when he heard this.

The young man thought that Mo Ling would definitely be interested, but he didn't expect such an answer. Seeing Mo Ling's reaction, the young man began to understand himself.

"I was originally from Wuxian County, and I came to Wolan City three years ago to work in the taxi industry. A few days ago, I went back to Wuxian to do business, but I didn't expect to meet Miss as soon as I returned to Wolan, which can only be said to be fate! ”

Certificate number: 365498XXX

Name: Fang Yu

Age of occupation: three years

……

Mo Ling glanced at the service supervision card in front of him, and judging from the information on the identity card, what the young man said was indeed correct: "Well, it's really a coincidence." ”

"Miss is really cautious, but you should really be cautious with a charming appearance like Miss, after all, there are a lot of wild wolves in this world who covet beauty!"

Leaning on the seat and stretching, Mo Ling looked out the window boredly. Last night, I drove for an hour under Liu Han's driving skills, and it took more than an hour to reach the Black Tower at the current speed.

"Anyway, Miss's destination is the Black Tower, right? Is Miss the one from the White Nights? So that day in Wu County was a mission? Wuxian seems to have an A-level ......"

The young man asked a few questions in a row, but the last question was interrupted before he could finish asking, and it was Mo Ling's mobile phone email that interrupted him.

"Confidential." As for the young people's questions, Mo Ling's brief answer was in two words.

[I think Xia Huang, you might be bored now, so I sent you an interesting thing to relieve your boredom, this is a decryption question! ] The question is to fill in the password corresponding to half past six according to the following rules. 】

Half-past four: 1-5-2-???

Five o'clock: 2-6-1-7-2-8

Half past five: 1-2-3-4-5-6

Six o'clock sharp: 1-8-1-7-5-5

……

After looking at the content of the email for a few seconds, Mo Ling knew where the question came from. This half-point password, coupled with the concert fire at half past six last night......

It seems that this is the reason why Operation Tachibanari was exposed yesterday. Looking at the numbers on the screen, Mo Ling pursed his lips.

There is no pattern to these numbers at all, the only special thing is the password of this 123456, maybe this is a breakthrough?

Judging from the only information, there should be two possibilities for filling in the password. The first is to push out the next password from the previous password, and the second solution has nothing to do with the previous password.

For example, the four passwords are 123456, 111110, 999993, and 899994. Then the rule of this string of numbers is that the former is multiplied by 9, and the first six digits are taken.

If you add difficulty to this password, you can replace the password planning 9 with time, such as 4 o'clock is multiplied by 4, and 4:30 o'clock is multiplied by 43.

If the former's password difficulty is one star, the latter's difficulty can be said to be two stars. If it was such a simple and regular password, Mo Ling would not need five seconds to crack it.

Although doing this kind of topic is unbearable for Mo Ling, who is an energy conservationist, Mo Ling can't refuse at the moment, in case this is Tachibana Ri who is suspicious of his identity and wants to test her character, it will be troublesome.

However, although he can't refuse to do the question, there is still a way to alleviate the trouble, Mo Ling replied to the email: [When you enter the password at half past six, can you check the password entered at six o'clock?] 】

【No】Tachibanari's promise is also very simple.

Mo Ling tilted his head, this is obviously good news, you can't check the password history, which means that the password should have nothing to do with the former's password.

Every half an hour, you need to memorize six numbers again, but it's very brain-draining, and if you accidentally forget it, it can be a big problem. Therefore, the initial digit of the password is likely to be replaced by a unique and unchanging key.

If you ignore the last digits, just look at the preceding digits, and the password becomes very simple, leaving only four simple digits.

4.30

5.00

5.30

6.00

These four numbers would be too simple to use directly, so it is likely that there are some simple operations. For example, 4.30 becomes 4*3=12, and 5.00 becomes 5*5=25.

Mo Ling closed her eyes and leaned back on her seat, her mind space floating with countless numbers and operation symbols, which were constantly rehearsed and combined, and reversed with the password.

It's just that what Mo Ling didn't notice was that when she closed her eyes and deduced the password, the young man named Fang Yu on the side stared at the screen in her hand a few times.

……

Two numbers appeared in the ocean of data in his brain that caught Mo Ling's attention: [261728*25=6543200] [181755*36=6543180]

Is it a coincidence that the first four digits of the results are the same? If you add the ...... of half past five Well, the five-point calculation method should directly use the two numbers 53, 123456*53=6543168.

I've already seen the answer! This password question is a key-based question.

If the key is set to X, then the password is: X/time. Time is used directly when it is an even number, and time is the square of the number when it is an odd number.

The reason why only the first four digits are the same is because the key is not divisible by time, so the first six digits of the password are taken. According to this method, the key is slightly larger than those numbers......

In terms of the thinking and arithmetic ability of the able, the operation of dividing six digits by two digits could not be simpler. It seems that after knowing the answer, the seemingly complex decryption question will also make people have such a simple question.

"One-three-eight-six-zero." The sudden sound in her ears made Mo Ling's body stiffen, and after she substituted the key of the 654321 into time, she came up with the answer was these six digits.

Mo Ling turned his head to look, and it was the taxi driver named Fang Yu who spoke, and his face, which was just delicate, seemed unfathomable at this moment.

"Ahh Sorry, I didn't mean to see that. Feeling Mo Ling's gaze, Fang Yu said awkwardly.

"This problem is indeed a bit difficult, if it weren't for someone like me, who is particularly sensitive to numbers and has won countless math competitions since I was a child, I would definitely not be able to solve it."

This man is lying, this is the answer that Mo Ling came up with through micro-expression analysis.

Mo Ling lowered his head slightly and was silent for a moment, then suddenly raised his head and showed a smile: "My name is Xia Huang, Mr. Fang Yu's talent is indeed very powerful, can you give me a contact information?" ”

"Well, although I admit that I am very attractive, but you are still underage, miss! Forget about leaving contact information or something, if you have a fate, we will naturally meet. ”

"Please, what does it have to do with leaving contact information and whether you are an adult or not! Hmm, it seems to be ......" Mo Ling was complaining in his heart, and the sound of the email rang again, making Mo Ling refocus his attention on the mobile phone screen.

[How, did you find the idea to crack this password problem?] 】
