God of unknown origin, please don't ask [criminal investigation]

Wen Xichun carefully raised his mobile phone to take a picture, trying to see the true face of that shadow.

It's just that the mobile phone's lighting range is limited, and it's still hard to see who the black shadow is.

It’s just that there are only two possibilities for people who appear here at this time:

Wen Xiyuan.

Or the real murderer.

Thinking of the possibility of the latter, Wen Xichun immediately? Turn off? Turn off the phone's lighting, try to walk as lightly as possible, and slowly turn around to a big tree next to him, intending to go around it, so as not to startle the snake.

He walked very slowly, and his heart beat violently.

The black shadow is only tens of meters away from me, but walking this? In just a few tens of meters, it seems to be walking on a road that will never end. After 10 minutes, there is still a distance to the black shadow. .

It's just very strange, that black shadow should have seen the light of his mobile phone, but after so long, he has remained motionless, showing no intention of leaving.

"Crack." Suddenly, the sole of his foot accidentally stepped on a dead branch, and the branch broke with an unpleasant sound.

After hearing the sound, the black shadow visibly moved, then turned around and ran away.

"Wait a minute!" Seeing that the situation was not good, Wen Xichun also got out from behind the tree immediately, and ran forward along with the black shadow.

The black shadow ran extremely fast, and coupled with the complex terrain here, it quickly disappeared into the dense forest of dead trees intertwined with each other.

All of a sudden, Wen Xichun lost his sense of direction. He stopped in a daze, looking at the crown of trees above his head.

However, when the cool white moonlight fell, I unexpectedly found a sharp corner on the top of the tree crown, like the roof of some kind of building.

He pushed aside the branches and walked towards the sharp corner.

As the pace progressed, the sharp corner also expanded a little bit, and finally revealed the whole picture.

It is an old baroque-style building. The outer wall looks dilapidated, and the walls are unevenly distributed in pieces. The walls are heavily stained and black, which looks like traces of being burned by a fire.

Wen Xichun remembered that this was a children's welfare home built here by foreigners in the early days of the founding of the People's Republic of China, but later because of a fire, many children died here, including teachers and childcare workers, etc. However, the local people regard this place as an ominous place, and no developer is willing to take over this piece of land, so slowly this place has been abandoned.

In the middle of the building is a tall building with sharp corners, and the shorter buildings on both sides are covered with two round domes.

Suddenly, with a flash of light and flint, Wen Xichun suddenly understood!

The triangle drawn on the paper left by Wen Xiyuan is not a pine tree at all, but the roof of this building, and the two circles also refer to the dome of the annex building.

Say? Ming Wenxiyuan has been here before!

Could she be hiding in it now?

Considering this possibility, Wen Xichun suddenly felt strange.

Changing history and changing the ending of my sister's miserable murder is nothing short of great news.But Wen Xichun is not stupid, there are many strange things in this world, and the facts have their own consequences. To change the ending, there must be a price to pay, after all, there is no such thing as a free lunch.

He walked to the gate of the building, looked up at the huge stone gate, and raised his hand to try it gently, but the gate remained motionless.

At this moment, he suddenly received a text message.

It was a message from an unknown number:

[You finally found it, so first? Find a way to get in. 】

Looking at this text message, Wen Xichun immediately replied: [Who are you. 】

[Want to know me? Who it is, it depends on your ability. 】

The provocative and disdainful tone made Wen Xichun feel a little angry, but he knew that he had to calm down at this time.

[Is Wen Xiyuan with you? 】

But this time, the mysterious person did not come back.

But the strange thing is, if this note is a reminder Wen Xiyuan left for herself, then she can go home and explain that she herself has not been restricted in her personal freedom; if it is kidnapping, this mysterious He was not in a hurry to kill her, but provided clues to himself in a way similar to the escape room game, allowing him to find her step by step.

What is he trying to do.

Wen Xichun clenched his phone tightly and looked up at the stone double door.

This kind of door cannot be opened by brute force, and there are probably traps inside.

He explored along the gate a little bit, and found that the gap in the middle of the gate was decorated with digital wooden blocks, and in the middle of the gap was a rectangular wooden strip with a side length of 10 cm, in which things could be placed.

It is a good door, why is it decorated with numbers on it?

Moreover, the shape of the numbers is not the traditional shape of numbers. The overall shape is square, square, and upright, a bit like a jigsaw puzzle.

Wen Xichun raised his hand, rubbed his fingertips lightly on the edge of the numbers, and with a little force, he picked out one of the numbers.

Understood, this mysterious person should be trying to stitch these numbers seamlessly into this square wooden frame by himself, which is a bit like the pattern of Constantine's number puzzle.

He immediately removed all the digits by hand, and there were a total of ten pieces, which were "0--9".

Wen Xichun had seen this kind of digital jigsaw puzzle before at an annual meeting of the police station, but at that time no one in the police station could spell it out, either there was an extra piece or a big gap was left , if you try one by one, then you may have to try up to 10 to the 10th power?, that is, 1E11 spellings. This? Maybe you may not be able to spell them together until the universe is destroyed.

Therefore, I can only try to recall the misspellings of my colleagues at that time to find the correct solution.

First of all, the corner position must prevent fully enclosed numbers such as 8 or 0. If 2 or 5 is placed at the corner, there will be a loss of space.

According to this rule, Wen Xichun tried to put the puzzle pieces together one by one, and put them together very quickly, but——

He looked at the number "1" left in his hand, this piece of the puzzle lost its place.

He disassembled all the numbers and placed them carefully for study.

Combining 3 and 4 is the most suitable for seamless connection, so you can regard these two parts together as a whole.

Wen Xichun tried again, but in the end there was an extra "5".

He felt that instead of trying to put the puzzle pieces one by one, they should treat the two-phase puzzles as several wholes, and judge the general position first.

Time passed by, and he stood like this at the gate for nearly half an hour.

"Ding--"

At this moment, the mobile phone suddenly received a message.

Pick it up and have a look, it's still the message from the mysterious person: [You still have 5 minutes, if you can't open the door, you are ready to say Goobye with your dear sister forever. 】

Wen Xichun suddenly opened his eyes wide.

Wen Xiyuan was indeed in the hands of this person.

It's useless to talk to him now, even if Wen Xichun leads him by the nose, Wen Xichun will admit it, as long as... Wen Xiyuan is safe and sound.

Wen Xichun took a deep breath and tried to calm himself down.

Think carefully about the mistakes your colleagues encountered when they put together this digital puzzle, and then urgently review it in your mind.

It can be seen that the widths of these digital puzzles are the same. If this is the setting, there are certain requirements for the side length of the square wooden frame, otherwise it will become a BUG.

He casually picked up three pieces of digital puzzles and put them in there.

[Also? In the last 30 seconds, did you figure out the answer? ] The text message was sent tirelessly again.

Wen Xichun looked at the empty digital puzzle in front of him, opened the phone and found the measuring tool.

[Countdown for ten seconds——]

[Five, four, three——]

What is the correct answer.

【two】

【One】

【time's up. 】

Wen Xichun slowly put down the digital puzzle in his hand.

【You are nothing more than that, it seems that it is me? I expect too much from you, then, tell your sister? Goodbye. 】

"Wait a minute." Wen Xichun raised his head, instead of sending a text message, he yelled directly.

Because he knew that this mysterious person must be able to clearly see and hear his every move.

【What else? Do you want to hear my sister's last words? 】

"The width of each jigsaw puzzle is three centimeters, and the side length of the square wooden frame is ten centimeters." Wen Xichun suddenly said such a sentence with unclear meaning.

[So, what do you want to express. 】

"I want to say that such a value can never be spelled out. From the perspective of length, this is a BUG."

At this time, the mobile phone message that had been ringing constantly became strangely quiet.

What will the other party do after being caught out of the little trick? Become angry and kill him?

but--

Following a slight vibration, the door in front of him suddenly opened a gap automatically, and thick black came out through this small gap.

Wen Xichun regained his composure and turned on the phone's light.

The light dimly illuminates a small corner, and through this faint light, one can vaguely see the ashes left by the fire that were once burned on the wall.

On the wall?, there is also an arrow painted with fluorescent agent, which is particularly conspicuous in the dark.

Obviously, the mysterious person wants to follow this arrow by himself.

He doesn't think there's anything wrong with following along. According to many years of experience, following along is the right choice, because this kind of psychopath who seeks pleasure in a certain way enjoys the desperate eyes of others , not just those bloody scenes.

Wen Xichun stroked the ashes on the wall, his fingertips were dark.

The place where the arrow crosses? It is a long corridor, with a lot of dust and children's toys that have not been completely burned in the corner.

But the more you walk, the heavier the echo from the bottom of your feet, which means that the floor is hollow and has a large area.

At the end of this dark corridor, a strange light can be vaguely seen not far away, it is ice blue, and it looks a little cool.

Wen Xichun couldn't help crossing his arms, and walked forward slowly step by step.

The farther you go, the louder the echo of the hollow under your feet becomes, and the clearer the bright blue door in the distance becomes.

"Click." Wen Xichun suddenly stopped in his tracks.

He heard the sound of water, and it was the sound of turbulent water.

He walked slowly into the door, and with the louder and louder sound of water, he also saw the scene in front of him clearly.

A huge circular underground cave, about ten meters deep, and at the upper end of the cave, there are two huge iron cages neatly arranged, and there are vaguely people gathering in the iron cages.

What is it, an animal?or people??

Wen Xichun took a step forward quietly, trying not to leave any traces, because he knew that that person could watch his every move from any corner.

It's just that no matter how careful I am, the sound of my footsteps can still be heard in this too empty cave.

The creatures in the cage seemed to have heard the sound of footsteps, and raised their heads one after another. In an instant, all the iron cages made an unpleasant "click" sound, as if they were hitting the iron cage hard together, and the sound was harsh. .
