As soon as Fatty turned around and entered the room to sit down, the extinguished lights in his cousin's sight lit up again. This time it was clear that the ten dots were a dialing screen.

The cousin's pupils dilated, and she memorized a series of numbers in surprise.

At this time, Ah Sheng said a few words on the other end of the phone and went upstairs. The three of them sat nervously in the living room.

"Master, can you tell me now? What kind of fried chicken is sold in the gourd?"

"Cousin, do you still remember the patterns and order you just saw?"

"It's not very clear, but the pattern is relatively obvious, so I can remember it more carefully."

The cousin picked up the pen and wrote down the position and order of the dots according to her memory.

"What do you think this pattern looks like?"

The two of them looked down at the pattern marked by Qiu Sheng's dark fingers.

"The up, down, left, and right sides of the remote control, and the dialing screen on the phone?"

"Absolutely. In fact, the Jiugongge code is not new. Almost all the mystery shows and TV series that Fatty has watched me these days have mentioned it. The most unbelievable thing is that there really is such a crazy person in real life.

Controlled the stair lights of two buildings to achieve record-free chat.”

“Chat without records?”

"That's right, as long as the person watching understands the meaning of the password, sending messages like this will not leave any chat records in any chat software, and the conversation will be completely confidential."

"Wow, the other party can go to this extent to scare us, it's quite cruel."

"The other party may not only be trying to scare us. During the day, I followed Fatty around the community several times and found that although there are many houses here, there are not many buildings with structures that can meet the needs of three rows of stair lights and window lights that he can control at will.

."

The cousin couldn't help but clapped her hands when she saw Asheng explaining in detail, her eyes full of admiration.

"Cousin, although I don't understand, I have to admire Asheng's learning ability. He has taken the time to read so many books these days, and it seems to have come in handy."

"Shh, don't disturb the master's reasoning. Since he can control the lights in the stairwell, he can control the lights in the entire community. Why did he only choose these buildings?"

"That's a good question. If you were a resident here and your home was always dark and light, what would happen?"

"I'll be scared to death."

Fatty nodded matter-of-factly, while Qiu Sheng shook his head.

"They will find it strange that in order to control lights to convey information, this person must use multiple lights at the same time. Then many residents will notice problems with the wiring in their homes at the same time, greatly increasing the risk of exposure."

"Oh, so he can only choose these two buildings."

"That's one of the reasons, and the other reason is because he is one of the residents in the two buildings."

"!"

The cousin and Fatty opened their eyes at the same time, with unconcealable surprise in their eyes.

"Master, have you guessed who he is?"

"Absolutely. The first time he 'turned on the light and sent a message' was at 12 o'clock in the morning, and the second time was at 10:30 in the evening. It's been so cold these days. If he just hid in a stairwell to scare you, that would be too much.

…”

Fatty saw the unbridled derogatory words in the master's contemptuous eyes.

"It makes sense. What's worse, I just signed a contract for my manuscript, and you caught him so quickly. I have no more material to write. What should I do?"

"Fat cousin, shouldn't we catch this pretender quickly?"

"You're right. I'm just talking casually. You can turn on my computer later and you can continue talking. I'll write as you say."

After saying that, the excited Fatty turned around, took out his laptop, opened the document and started typing.

"It's not your turn to be anxious this time, 79."

The cousin looked at her cousin who was full of energy and muttering to himself, and reluctantly twitched the corner of her mouth.

"People are like that, they go crazy when they have material. Don't be surprised, Asheng, why did you just say that he lives in these two buildings, and why did he only let me see those flashing lights?"

"To be precise, he was delivering the same message to both of you at the same time. The reason why he turned off the lights after Fatty came out was because Fatty was talking to me on his cell phone at the time, and the other party thought that Fatty was recording.

Just turn off the lights."

"No wonder, Master, you asked me to walk in and then walked out, so I said you must have some secret."

"That guy just flashed his lights for so long, what did he say?"

The cousin raised her hand enthusiastically and picked up the phone with one hand.

"Here, let me type it out to see what he said... projection, shadow, instrument? What does this mean, his Double Twelve shopping list?"

"The projector, could it be..."

Fatty guessed it, and Qiu Sheng's next words confirmed his answer.

"It seems that someone spontaneously raised their hand to 'answer' our first question. Fatty, didn't you see a woman's face in the kitchen window last time? If you guessed correctly, the other party secretly photographed a haggard lady in the community.

Then put it in the projector and project it through the image, specifically to show it to you when you enter the kitchen."

"Me! No wonder I looked left, right, up and down, and that face was stuck to the window like a sticker. I almost spit on my sleeves and rubbed it against the glass."

"Cousin Fatty, you don't have to show respect, we all know what happened to you in sorrow." The cousin put her hand on Cousin Fatty's shoulder and nodded with deep regret.

"The news is still being replayed. I will never forget the harm that guy caused me!"

Fatty picked up the phone excitedly, looked at the mark of the next pattern and pressed a series of numbers, and instantly shuddered.

"This is the lock screen password of my phone..."

"!"

"Fat cousin, why did he show me your lock screen password?"

"Cousin, is this the point? The point is that my phone may be hacked."

Qiu Sheng had a sullen face, looking like he was worried all night.

"Fat boy, think clearly, who is most likely to see your lock screen password?"

"Being seen? Didn't the other party hack my phone and see my lock screen password?"

"If the other party has such ability, why should he condescend to pretend to be a ghost in Community 79 and scare the residents here."

"That's right, the more capable a person is, the more important things they do. How can a real master do such villainous behavior?"

Fatty stood up, put his hands on his back, and walked back and forth in the living room, thinking carefully about the question Qiu Sheng just asked in his mind.

"If you want to say that there are many people who have snooped on the lock screen password of my mobile phone, I can only say that it is easiest to see...when I queue up to have my throat checked. In short, there are too many opportunities."

"At least you can remember, first of all, you can't get into trouble, because the other party's purpose is probably to make you feel panic and fear."

"What's in it for him if he does this?"

"My master has a saying that is right. He often says that we can never understand the thoughts of a bad person. Many times he has thousands of reasons to be a bad person, but he can never find a reason to be a good person."

"Master, if you can deduce who he is within half a minute, I will send my cousin to take him to the hospital in person and spend all his medical insurance."

"Hahaha, no problem."

The cousin hammered her palm with a fist, ready for a fight at any time.

"What if you have more than one person to deal with?"

"more than one?"

The TV screen just reflected my cousin rolling up her sleeves.

"It would be too cost-effective if they controlled the circuits of several buildings just to scare you two. They did this to use this special method to communicate messages."

"Master, it happens to be the 2022 World Cup. Are these guys illegally placing bets on behalf of others?"

"It cannot be ruled out, but the possibility is somewhat low. Money transactions must also involve statistics. Without records, it will be difficult to count errors. Cousin, do you remember the first time you saw these stair lights, they were connected

Two lamps, two lamps, light together and dark together?"

"Yes, we also drew very strange patterns at that time. Does it have any special meaning?"

"That's another nine-square grid password. The result was a bit beyond my expectation. It happened to be the news headline of a certain app."

"News headlines? Do you have to be so sneaky when talking about news?" The fat guy sitting in front of the computer didn't understand.

"If it were yesterday's news headline, everyone could see it, so of course there is no need to be so sneaky."

After hearing this, my cousin figured it out.

"They are passing on tomorrow's news headlines, which haven't been posted yet."

"Yes, I just can't figure out how they know the news headlines that are about to be sent out, and why do they use such a roundabout way to deliver the news?"

"What news are they delivering?"

The fat fingers that jumped quickly on the keyboard stopped, and the fat boy stretched out half his head, his eyes were very concerned.

"It's a headline about railroads."

"railway?"
