These 6 digits are: 122334, Feng Yan entered these 6 digits into the password interface of the lock screen and successfully unlocked them.

There is only one APP in the whole mobile phone, which is WeChat, at this time there is a '1' in the upper right corner of WeChat, this is a prompt for unread messages, after Feng Yan clicked in, he found that the name of this WeChat account is called Yanfeng, and there is only one friend in WeChat, that is, the person who just sent a message, this person's name is actually called Feng Yan.

The language message reads as follows: "Hello, I'm a killer, my name is Feng Yan, I heard that you are proficient in cat and mouse games, I want to play a game with you, do you see the tallest and only building in front of you with lights?" I'm right there, you need to get into the office building, I'll be waiting for you on a certain floor, find my exact location in 20 minutes, or when the time comes, I'll show up, kill you, and the timer starts. ”

Feng Yan looked up, and at a glance, he saw the tallest building not far away, and the only one with a few floors lit.

"It's really~ What time is it, I'm still working overtime, unscrupulous boss, I don't treat people as human beings at all."

It should be midnight.

Feng Yan muttered a few words, put the phone in his pocket, tried to step on the accelerator, and found that he could accelerate when he stepped on it, Feng Yan immediately drove the Jetta as a Gundam, and in less than 3 minutes, Gundam ...... Ah no, Jetta drove downstairs to the office building.

Before getting out of the car, Feng Yan searched the Jetta car and found that there was nothing useful, so he closed the door and walked towards the door of the office building.

In the hall on the first floor of the office building, there is nothing special, and the first thing Feng Yan has to do is to accurately locate which floor the killer is.

"Ah~ forty or fifty floors, where is the guy pretending to be me?"

Although there seemed to be no way to do it, Feng Yan's expression was not too distressed, he looked around casually, and soon found the sign on each floor, pasted on the west wall, with the information of all the units settled on each floor.

"Well...... Business is not easy to do, and not every floor is an office enterprise...... Ha, I see, it should be this layer. ”

Feng Yan's eyes locked on the 17th floor, and there was only one OEM called 'Yiye Teahouse' on the entire 17th floor.

Feng Yan took out his mobile phone again, clicked on the killer's voice and listened to it again, and turned the mobile phone to the maximum.

On the clouds, Xuanyuan asked Liu Zheng in a frightening dream: "Have you guessed which layer the killer is?" ”

Liu Zheng nodded and said, "It should be on the 17th floor." ”

Xuanyuan was shocked: "Is there a basis?" ”

Liu Zheng: "Just the first time I played the voice, I noticed that when the killer was speaking, there was background music, although it was very small, but I still heard some when he spoke, it was a guzheng version of the mountains and flowing water, like this very elegant song, the place where it was played was very limited, you and I can think of it, it is nothing more than some very elegant places, now there is only 17 floors on the wall is a teahouse, and there are gyms and cafes on other floors, But it is impossible for such a place to play this kind of soothing tune, or the guzheng version, so he should conclude from this that the killer is on the 17th floor. ”

As soon as Liu Zheng explained this, the audience outside understood that Feng Yan, this kid wouldn't bother to explain for this kind of thing, this is just a mental space, and Rory's wordy explanation will not have many performance points to add, unless a plot NPC asks him, otherwise he will only do things in his own way.

"Mountains and flowing water, hum, I really know how to pretend, is this a killer cultivating his own sentiments?"

Feng Yan came to the elevator entrance, pressed the button, and the only elevator door that was still running opened, and after Feng Yan entered, he pressed the 17th floor, and the elevator rose slowly.

After coming to the 17th floor, as soon as the elevator door opened, the door of Yiye Teahouse appeared in front of him, but Feng Yan did not rush in, but walked to the right, he wanted to understand the layout of the 17th floor first.

The whole 17th floor is a hollow-shaped design, the middle is the elevator lift, the southeast, northwest and four sides are offices, but as Feng Yan just saw below, there is only one teahouse on the entire 17th floor, located in the north, the teahouse will open up the entire north office, the north is all the territory of the teahouse, and the other three sides are locked doors.

There are three toilets on the entire fourth floor, located in the southeast, southwest and northwest corners, and these three places are open.

Feng Yan nodded self-consciously, and returned to the Yiye Teahouse again, the entire 17th floor was lit up, and the Yiye Teahouse was naturally brightly lit, after pushing open the glass door and entering, the melodious sound of the mountains and flowing water came out, it seems that Liu Zheng's explanation is completely correct, and the killer should be the voice message sent to Feng Yan in the Yiye Teahouse.

After a brief turn, Feng Yan did not find the killer, which was also expected, Xuanyuan Horror Dream obviously would not let him pass the test so easily.

"So in other words, the killer sent me a voice message in the teahouse, but he is not necessarily still in the teahouse at this time, apparently he left here after sending me a voice message, so where did he go?"

Feng Yan muttered to himself while starting to search the entire teahouse carefully, he didn't leave in a hurry, because he thought that there must be a hint in the teahouse that triggered the next plot, if it weren't for that, in the background music of WeChat, there would be no mountains and flowing water, everything pointed to a leaf teahouse, and now he came in but returned in vain, which was obviously unreasonable.

The interior of this teahouse is very simple, although the space is huge, but there are not many furnishings, and the decoration is exquisite, obviously not ordinary people can come in and drink tea.

Feng Yan walked all the way to the west, looking around, but there were no clues to the simple furniture, and he could immediately judge it at a glance.

At the end, there is an open study, which is naturally decorated in Chinese style, with a high long table in the center, next to which there is a pen, ink, paper, and inkstone, which is obviously prepared for writing or painting, and this table is covered with a piece of rice paper.

Feng Yan came to the table and began to carefully observe this piece of rice paper, and after a while, he found clues, there were water marks in some places of this rice paper, and the water marks had a trace of wrinkles, as if someone had written on it with a pen, but strangely, there was no half a word on the paper.

Feng Yan smiled and said: "This is too simple, isn't it just that the words are written with invisible materials, and they will be visible as soon as they are stained with water, pediatrics." ”

Saying that, Feng Yan moved a pot of daffodils next to him, pulled the daffodils out of the water roughly, threw them to the side at will, and then took the daffodil pot, dipped some water with his hands, and splashed it on the paper.

"Eat deflated stupid, haha."

"It's not very reasonable, Crazy Yan's approach should be fine."

"There's definitely a lack of triggering plots."

While the audience in the live broadcast room was discussing fiercely, Liu Zheng on the cloud also frowned, while Xuanyuan Jingmeng continued to drink leisurely.

Seeing that it didn't work, Feng Yan was not annoyed, he put down the daffodil pot and began to observe around the long table, in his opinion, the hint would not leave the table half a meter away, and soon he found a new clue.

Feng Yan noticed that the placement of the four-legged long table was not quite right.

"Have you ever been moved?" After Feng Yan looked at the positions near the four table legs, he simply sat on the ground and muttered to himself.

In the clouds, Liu Zheng, who saw the table legs and the nearby scene through the large-screen lens, soothed his brows and said, "I know, the table has indeed been moved, and you have set up a very clever game." ”

Seeing that Xuanyuan didn't speak, Liu Zheng continued: "There are four slightly whitened marks on the ground, generally when the table is placed in one position for a long time and has not moved, after moving it, there will be white marks in the four places where the four table legs are pressed, this is a unique mark that has been pressed down for a long time, especially the floor of this study is still made of floor, and the marks will be more obvious."

Obviously, the location of this table was not originally from this position, and it must have been moved recently. ”

As soon as Liu Zheng finished speaking, Feng Yan raised the table, looked at the four white positions on the ground, and accurately moved the four feet of the table to the position of the four seals, and the position after the move was about half a meter equivalent to the entire table being moved towards the right hand side by more than half a meter.

Coincidentally, there was a light bulb above this position, and the light of the bulb hit the paper directly, and some words instantly appeared on the white rice paper.
