Survival in the dormitory, I was pulled into the management group

Without waiting for Chen Bei to ask further, Feng Zhiji took the initiative to explain:

"There are 45 dots on the left, 9 in a group, and one dot in each group is black, so we can infer that it is a nine-square grid."

"I see. But it shouldn't be that simple, right? Otherwise you wouldn't be standing here staring blankly." Chen Bei said.

"Well, we are indeed stuck here. We just tried two combinations of numbers, and both were wrong. The reason there are two combinations is because there are two ways to arrange the Nine-square grid."

"In the first one, the number in the upper left corner is 1. In the other one, it is arranged like a calculator, and the starting number in the upper left corner is 7."

After hearing this, Chen Bei understood.

Two ways of arranging the nine-square grid.

123

456

789

-

789

456

123

-

Look at the first group of nine-square grids on the door, as shown in the picture.

○ ○ ○

○ ○ ○

● ○○

The dot in the lower left corner is black.

According to the two arrangements of the nine-square grid, the number is either 7 or 1.

And so on.

The last four numbers are also clear at a glance.

Finally, two five-digit numbers are obtained.

74825

14285

Feng Zhiji and his team had tried these two numbers, but none of them was correct.

In other words, beneath this code that appears on the surface, there are other mysteries hidden.

Chen Bei couldn't help but think of Xuejian and Leo.

If both of them were here, we would probably get the correct answer quickly.

The people present stared at each other as if they were reading faces.

Suddenly, a creepy scream came from behind the door.

"Let me out quickly!"

The sound was so shrill and strange that it pierced the eardrums.

Chen Bei's sanity attribute dropped a few points and he frowned.

The job description said there was a little girl trapped inside.

The heart-wrenching roar just now was not something a little girl could make.

"The guy inside will roar from time to time. If you enter the wrong unlock code, it will trigger a more severe punishment, causing a blow to both your health and sanity." Feng Zhijidao.

"So you don't dare to try the password randomly." Chen Bei said.

"Ah."

"74825...14285...14285...14285...Why do they feel familiar?"

"familiar?"

"I think I've seen it somewhere."

"Is it in the game?"

"No, not in the game... let me think."

Hearing Chen Bei say that he was familiar, everyone present looked at him.

Chen Bei frowned slightly and tried hard to recall, as if he was searching in a folder of memories.

Suddenly, his eyes lit up and he thought of a more complete number. He walked quickly forward, entered six digits on the combination lock, and pressed the confirm button.

Only five digits 14285 can be obtained on the door.

If you add a digit 7 to the end, you get 142857.

This is a very famous "revolving lantern number"!

142857 has a cyclic nature.

Multiply this number by two, and you get 285714. Multiply it by three, and you get 428571. Multiply it by four, and you get 571428... and so on, until you multiply it by six.

285714

428571

571428

The answers are always a few fixed numbers, only the order changes. This is the magic of the revolving lantern numbers.

Chen Bei entered the password, hoping that it would be correct.

"Ahhhh!!!"

Unexpectedly, an even more shrill scream was heard from behind the door.

At the same time, a sinister beam of light shot down from above and hit Chen Bei, leaving no chance for resistance or dodge. It was a forced hit.

Health -300

Sanity -80

Chen Bei was punished doubly and his body shook three times.

"It's not right..." Chen Bei said depressedly.

"The number you just entered is the six-digit number 142857... Oh, I see, that's what it is. This is one of the revolving lantern numbers." Feng Zhiji suddenly realized.

"But that's not right."

"That shouldn't be the case... The number we inferred should be correct."

"Try another version?"

"You mean 748251?"

"Well, someone go and try. I just got punished, so I don't want to try anymore."

There are indeed warriors present.

One player entered 748251, even though he didn't quite understand why he had to enter that number.

Another beam of light shot down, hitting the player who entered the wrong password.

Wrong again!

Either the players are thinking in the wrong direction, or they don't have enough information.

Chen Bei was still the same as usual and started to sneak a peek at the management group again.

The administrators' attention is all here, they are chatting.

[They only completed the number of the revolving lantern, but did not notice the hidden clues on the door frame.]

[The tip is hidden in such a dark place, so it’s normal that we can’t see it.]

[It's quite interesting to see them standing there stupidly in front of the door.]

-

Chen Bei's face became a little more gloomy.

It turns out to be a problem of insufficient information!

There is no point in thinking more if you don't have enough information.

"Let's check the door and the wall again. Maybe there are some clues that we haven't noticed yet." Chen Bei suggested deliberately.

The players present had already checked it and now checked it again.

Chen Bei moved closer to the door frame and looked carefully, but found nothing on either side.

Could it be on top?

Chen Bei used the Thousand Hands Cloak to push himself up so that he could see clearly above the door frame.

There was a line of inconspicuous small words hidden on the upper part of the door frame.

"Reverse revolving lantern"

From a normal perspective, the area above the door frame is a blind spot!

No wonder no players saw them here before.

"Reverse the revolving lantern...does that mean I should input the revolving lantern number I just got in reverse order?"

Chen Bei went down and re-entered a number, turning 142857 into 758241.

A piece of electronic music started playing, and a green light came on on the door, then it opened automatically.

The password is finally correct!

Everyone present's eyes lit up and they all looked towards the open door.

The door opens very slowly.

Looking through the open part, the room was pitch black.

Then a strange laugh came from inside.

"Hehehe...the door is finally open. Whoever opened the door, please help me out. This is also part of the job."

The tone of the voice was that of a girl, but it was eerily more gloomy than a normal human voice.

It turns out that just opening the door is not enough, there are additional requirements.

Everyone looked at Chen Bei who opened the door.

"What do you think? Do you dare to go in?" There was a hint of provocation in Old A's tone.

Chen Bei turned on his blood pupil vision and looked inside, but all he saw was still pitch black.

I don’t know what dangers are hidden in this darkness.

Maybe opening the door is just a piece of cake, the hard part is yet to come!

But now that things have come to this, we can't back down.

Chen Bei created a layer of ice armor to wrap his entire body, then wrapped his arms with coiled snake patterns and held the Golden Money Sword in his hand.

After making these preparations, I stepped in and entered the unknown darkness.
