The characteristics of these videos are too obvious to be recognized at a glance.

Writer Xu said firmly: "It's a number."

"The empty room is a partition." Kang Mucheng arranged the videos in five rows.

The numbers obtained are as follows:

179

17931

183

317946

1793At

the same time, a remote control was also found on the side of the shelf. The projector used for the exhibition hall is set uniformly by the central air conditioning. There is no need to use it at all. It is very likely a machine.

Writer Xu took it and pressed the numbers on it.

No response.

"What the hell is this?" He was puzzled and dissatisfied.

Jian Jing had been outside for a long time without any response, so she couldn't help knocking on the door: "Mr. Kang?"

"I'm fine." Kang Mucheng took off his suit jacket, leaned against the door and briefly told her the results, "This string of numbers should be a password."

Jian Jing agreed and sat on the floor in distress.

She had just touched the threshold of converting letters into numbers, but she had no idea about the rules of numbers.

What does this string of passwords mean?

Inside the door, Kang Mucheng took his mobile phone and used the built-in calculator to add, subtract, multiply and divide, trying to find the connection between several numbers. Unfortunately, he found nothing.

"It's neither arithmetic progression nor geometric progression." He calculated, but had no clue. "Sometimes it's big, sometimes it's small, there's no pattern at all."

Writer Xu squatted beside him, pondered for a while, and said, "Four of the five are 179, does it have any special meaning?"

Kang Mucheng frowned: "What does it mean?"

"Suppose 179 is X, then it becomes like this." Writer Xu's fingers flew, typing out the new sequence in the memo.

The original sequence is:

179

17931

183

317946

1793

After replacing 179 with X, it is:

X31

183

3X46

X3

Kang Mucheng was silent for a while: "So what?"

Writer Xu: "..."

Awkward silence.

"I work in writing, and you ask me to do math." Writer Xu scratched his head and admitted frankly, "I have no idea. What is this? I can't understand it."

Kang Mucheng: "Same."

"Aren't you a top student at Columbia University?" Writer Xu said doubtfully.

"This password has nothing to do with my major. We didn't find the right way to think." Kang Mucheng thought and knocked on the door. "Jingjing, have you solved it?"

Outside the door, Jian Jing sat cross-legged on the cold ground and asked them, "What does the remote control look like?"

"It's just an ordinary one, with a small screen on top and buttons on the bottom." Kang Mucheng answered.

"Are the buttons numbers or letters?"

"Both."

Is it a numeric keyboard again?

The first number is 179. 1 cannot be pressed 7 times, and 7 can be pressed once, but it conflicts with 9. It is not the same password type as the previous bathroom password.

Why does 179 appear so many times? Is there something special about 179 on the keyboard?

Jian Jing opened her input method and moved her fingertips from "1" to "7" and then to "9".

Hmm.

She had an idea and drew it again. That's right, 1-7-9, it's L.

What about 17931? O? No, it's O.

Got it.

183 is V.

317946 is E.

1793 is U.

"Mr. Kang, I solved it." Jian Jing got up, "It's LOVE U. Five letters."

Kang Mucheng was surprised, then he suddenly realized it, picked up the remote control and pressed the letters.

After the five characters were entered, there was a loud "click" and a box on the shelf fell out. He picked it up and saw that it was "The Skeleton Key".

Master key.

He opened the box and found a brass key besides the film roll.

He inserted it into the keyhole and twisted it. The bolt moved and opened the tightly closed door.

Jian Jing obviously sighed and couldn't help asking again: "Are you okay?"

"It's okay." Kang Mucheng felt warm in his heart, "Are you okay? What's going on? Where are Mrs. Qin and Mr. Qin?"

Jian Jing shook her head: "Anyway, the villa's security system has been activated and we are all locked in here." She suddenly remembered something and asked hesitantly, "Mr. Kang, a private security system would have... um, something with greater lethality?"

"Of course." Kang Mucheng said, "Ordinary people can't carry guns, and the security system has no power. How can we stop crime?"

Jian Jing was confused: "Ah?"

Her stunned look was particularly interesting. Kang Mucheng couldn't help shaking his head and explaining the relevant knowledge to her: The crime rate in this world remains high, and people's lives and property safety are under great threats. Under the premise of banning guns, people will choose to install various security systems to ensure their own safety.

Under normal circumstances, security companies with national qualifications will not install lethal equipment, mostly iron cages, power grids, anesthetic gases, etc., mainly to control criminals.

However, this is not necessarily the case.

Some people will modify the equipment themselves, and some people will hire some less formal teams. The security facilities they build may have a certain lethality.

Jian Jing rubbed her temples. She blamed the system. It was not the system that made a wrong judgment, but the world had changed.

"This villa is full of treasures," she chose her words carefully, "we'd better not take risks."

Kang Mucheng had already realized this when he explained it to her, and his expression was solemn: "You are right." He walked to the original staircase, fumbled up and down for a while, and confirmed, "It's just a wall, nothing."

"It must be a mechanism." Writer Xu was originally interested in the dark room of Yuhui Villa, and immediately walked back and forth, trying to find out if there was anything that looked like a starter mechanism.

The corridor is very long, with two plaster sculptures in the middle arranged in proportion.

One is Cupid, and the other is Venus with Broken Arms.

Writer Xu tried to turn the two statues, but the threads did not move. He couldn't help but hold his chin and muttered: "It's completely different from what I thought."

Kang Mucheng was more pragmatic. Seeing that it was troublesome to find the agency, he went straight to the end of the corridor and tried to push open the window.

The windows of the villa could not be opened completely. They could only open a gap from the bottom for ventilation. However, it was only three fingers wide, so not even a human could get out.

He took out his mobile phone, and the credible number was still a cross.

"There is a jammer." Kang Mucheng pinched his eyebrows and shouted loudly, "Boss Qin, Mrs. Qin?"

The voice floated into the rain and never came back.

At this moment, in the storage room next to the cafe, Editor-in-Chief Guo and Boss Qin were talking.

"Is it open?" Editor-in-Chief Guo crossed his arms, "It's so stuffy here. It's just a warehouse, why is there a smart lock installed?"

The café was crowded, so they chose this storage room to talk. In the middle of the conversation, the power went out and the door was locked, trapping the two of them here.

"The villa needs constant temperature and humidity, so it's convenient to have an intelligent system." Mr. Qin entered the wrong password again and paced impatiently, "What the hell, my password failed."

Editor-in-Chief Guo remained calm, but there was a hidden trick in his words: "The password your wife told you is wrong?"

"It's right, it works fine normally." Mr. Qin frowned, "Maybe the system has been reset and a new initial password is needed."

Editor-in-Chief Guo asked: "What should I do then?"

"Originally, it will be sent to my mobile phone after the reset, but now my mobile phone has no signal." Mr. Qin impatiently pulled off his tie of the same color as his wife's dress and threw it aside, "I can only find an emergency password."

Editor-in-Chief Guo glanced over the tie and asked: "What emergency password?"

"According to the system settings, each area will have an emergency password, and you can leave once you find it." Mr. Qin was looking through the rows of coffee beans and roasting ingredients on the shelf, looking impatient, "I don't know where this room is hidden, you come and look for it, we have to leave quickly."

Editor-in-Chief Guo picked up a bag of cassava flour and flipped through it casually: "What are you afraid of? Haven't you been planning to divorce your wife for a long time? If you see it, you can see it, so you don't have to keep silent all the time."

Under the weak light of the mobile phone, Mr. Qin's eyes flashed with gloom, but his words were perfunctory: "It's too ugly to make a fuss like this, and it's not good for our reputation."

Editor-in-Chief Guo didn't say anything, turned his back, and curled his lips slightly, mocking her.

How could she be a naive person who didn't understand the meaning of words when she could get the position of editor-in-chief in one of the best publishing houses in the country? But this man thought that she was really blinded by her own greed and would just take whatever he said at face value.

He clearly didn't want a divorce. But

if she didn't divorce and played love games with him, did she think she was in need of love?

What she wanted was the identity of Mrs. Qin.

"Is that all?" She spoke in a gentle tone, as if she was convinced, but a little worried. "You and your wife were so affectionate before, don't you want to get a divorce?"

Mr. Qin asked back, "Do you believe that it was just a casual affair?"

Editor-in-Chief Guo stopped talking.

After a moment, "I found it." Mr. Qin found an iPad on a shelf. In addition to the account records of the incoming goods, there was also an emergency code 51361 written in the memo.

He immediately ran to the door to unlock it, feeling relieved.

Editor-in-Chief Guo shuddered suddenly, and a dark cloud passed by.

51361, it sounds like... I'm going to kill you?

"Ah." Jian Jing sighed heavily, sat down with her back against the wall, and sipped the cold milk tea.

It was 6:48, and two hours had passed since they were trapped, but they still hadn't found a way to leave the third floor. It was past dinner time, and everyone was hungry, so they could only fill their stomachs with milk tea, coffee, and popcorn sent by Mrs. Qin.

Writer Xu was crunching caramel popcorn, making small talk: "What kind of company is this? They are doing such a good job. They just sealed off the third floor and didn't let us go out?"

"No, security systems have ratings." Nowadays, the people who use security systems the most are the rich, and Kang Mucheng happens to be a rich man. He explained, "Different levels have different plans. Private pavilions are at most Class B. Even if they modify the equipment themselves, the structure remains unchanged, and there must be an escape route."

Jian Jing was still confused: "What rating?"

"Ordinary residences are Class D, and only have alarm defense facilities. For example, once someone invades your home, the alarm will be automatically sounded, and all door locks except the front door will be automatically locked to ensure your safety as the top priority." Kang Mucheng was very patient. "Companies and enterprises are Class C. In addition to alarm defense, there are also secret door mechanisms to facilitate the police to capture intruders."

"Class B means there are control equipment?"

"Yes, tear gas and power grids can be used, but according to regulations, escape routes must be left, and it is illegal to seal them all." Kang Mucheng said firmly, "There must be a way to leave here, let's look for it."

"Wait," Jian Jing stopped him, "What's Class A?"

Writer Xu laughed: "Class A can only be installed by government departments, and they are allowed to kill."

"I see." Jian Jing tried hard to absorb the common sense settings that were different from the past world.

"Writer Xu, come and take a look at these paintings." Kang Mucheng used his mobile phone to shine on the paintings on the wall, "Could the agency be hidden here?"

Writer Xu perked up and straightened up to pick them up: "Take them down and have a look."

"I'll do it." Kang Mucheng was 1.85 meters tall and could easily take them down without using any footrests.

The paintings with frames were a bit heavy, so he took them down one by one and placed them neatly on the floor tiles, aligning them front and back. Jian Jing squatted over to check and couldn't help but complain: "Mr. Kang, your obsessive-compulsive disorder is quite serious."

"Occupational disease." Kang Mucheng did not deny this minor problem. He hated errors in email format, incorrect word order or incorrect use of punctuation. Once he encountered them, he wanted to circle them with a pen and correct them.

Undoubtedly, it was the sequelae of being an editor.

Writer Xu whispered, "This kind of editing is the most annoying."

"That's right." Jian Jing agreed subconsciously.

Kang Mucheng: "Ahem!"

The two writers were suddenly silent.

Jian Jing fumbled back and forth on the picture frame, and with her extraordinary observation, she soon found a discordant bulge on the side of the frame. Scratching it with her fingernails, she found a key hidden inside.

"It really exists." She was delighted and puzzled, "What's the point of hiding it in the painting?"

"It's dark under the light." Writer Xu took the key and turned it around twice, "There's no keyhole on the wall, is this the door to open?"

He was referring to another room on the third floor.

Yuhui Villa is a residence, so it is not as spacious as a large art museum. The second floor is the main exhibition hall, and the third floor is much smaller, with only three rooms, a private theater, a toilet, and a locked exhibition hall.

Insert the key, twist, and open.

Jian Jing: "..."

The toilet is a smart lock, and the exhibition hall is a normal lock. Is there something wrong with this world, or is there something wrong with her?
