Optical reaction, also known as actinization, refers to the chemical reaction caused by the action of light, that is, the chemical reaction that occurs when the substance absorbs light energy under visible light or ultraviolet irradiation, such as carbohydrate synthesis, dye fading in the air, film photosensitivity, etc., which contains a wide range, mainly photosynthesis and mapping.

Shadow, an optical phenomenon, belongs to mapping optics, a darker area formed by an object blocking the propagation of light, presupposing that the light and the object, once generated, can extend the projection of the object in the direction of the light.

Projection depends on what is illuminated, and all tangible objects or living beings can produce shadows, shadows, invisible matter, which can never be escaped.

In the light of the day, whether it is human beings or other creatures, who in the world can get rid of their shadows?

And at this moment, the lights are bright, and the whole building is brightly lit.

The man with glasses who figured this out couldn't help but sweat like rain, and his already trembling body was even more shocked by the speculation in his mind, the only strange thing was that although he was trembling in place, he still didn't make much movement, but looked around after turning back and scanning the face in the eyeshadow again.

It is worth mentioning that if you don't consider that the mission time is currently in a state of stopping, the man with glasses is really silent this time, and he is currently observing his surroundings, his eyes scanning everywhere from time to time, observing everything he sees.

In the field of vision, there is nothing special about the environment, the floor space is still a seemingly ordinary business building interior scene in addition to the bright lighting, as a whole, it is still a seemingly ordinary business building interior scene, after a long observation, Zhao Ping moved, he moved again, moved his legs and walked straight towards a room at the end of the corridor, although the snow-white door of the room was printed with the same words as the surrounding office, but the words were not three words for office.

Dada

Hengfeng Building is indeed a taller building in the whole city, and the height of 20 floors is enough to show that this building is extraordinary, and the hard work pays off, although he never dares to take the elevator, but with the help of lighting equipment to restore and the visibility of the vision is clear, running for a long time, He Fei and the four of them still arrived at their destination a few minutes later on two legs, and arrived at the highest floor of Hengfeng Building, the 20th floor.

"Whew! Call! Call! ”

"Huh, I'm grass, I'm really tired, which stupid fork built the building so high? I really want to greet his ancestors for eighteen generations now, whew, whew"

At this moment, with a series of somewhat rapid breathing sounds and Peng Hu's words full of dissatisfied curses, the four executors who stopped running and were collectively located at the staircase on the 20th floor were all panting and sweating without exception, Peng Hu and Cheng Ying were okay, don't look at the bald man scolding, but he can actually hold on with the same strong physical fitness as Cheng Ying, and the cursing in his mouth is just whining, but He Fei and Ye Wei are a little different, Although these two people often exercise their physical fitness in the hell train, and their physical fitness is indeed better than that of ordinary people, these ten or twenty layers still tired the two of them enough to run up in one breath.

Because of this, if Peng Hu, who has a strong physique, and Cheng Ying, who has excellent physical fitness, are just out of breath, then He Fei and Ye Wei, who have been running for a long time, are really sweating, and they are currently holding on to the wall with one hand and the other on their knees, gasping for breath.

Of course, tired and tired, the reason why they are willing to ignore their physical strength, and even rush here without resting halfway is still very clear about their purpose, sure enough, after barely breathing, He Fei, who recovered, was the first to walk towards the center of the corridor, and similarly, seeing He Fei have moved, Ye Wei, Cheng Ying and Peng Hu, who have the same purpose, also followed.

The next thing was very simple, they didn't even have to look for it, and as soon as they arrived in the middle of the corridor on the 20th floor, everyone found that thing, the thing they had been looking for for a long time.

At this moment, on the wall of the corridor in front of the four people, a black machine with a half-mosaic wall and half exposed appeared in everyone's field of vision, the machine is not large, although the shape is not common, but the obvious half-palm-sized groove in the center is enough to prove that this is a punch card machine, which belongs to the working machine used by security personnel to prove the number of patrols when patrolling, and the middle-aged security guard in the video preview did swipe the card on this machine before he died.

Seeing that the target was found, without waiting for He Fei, who was staring at the machine, to make a move, Peng Hu immediately reached into his pocket as if he had an understanding, and began to rummage through his pockets, not to mention, under this flip, the bald man really took out a magnetic card from his trouser pocket, a black magnetic card that looks like a bank card.

"Hey! Found it, the curse didn't lie, I really got an extra magnetic card in my pocket, if I'm right, I think this thing should be used to swipe in front of the machine. ”

While speaking, the bald man's hand holding the magnetic card also subconsciously pasted the card swipe of the machine in front of him, however

Syllable!

For some reason, just as Peng Hu was about to paste the magnetic card in his hand on the machine, He Fei on the side suddenly reached out and grabbed Peng Hu's wrist.

"Brother Peng, wait first."

"Huh? What's wrong? ”

He Fei's blocking move surprised everyone present, after all, the purpose of the four of them coming here was to check in, and the purpose of punching in was to try to break the time stop, not to mention that it was He Fei himself who first proposed the punch in strategy, so when he found that he was stopped by the other party, for a while, not only Peng Hu, who was stopped by the young man, asked with a puzzled face, but even Ye Wei, who had always been calm, and Cheng Ying, who had always been alert in the mission, both turned their suspicious eyes on He Fei and threw them at the young man who had a strange expression since he saw the machine.

It is true that most of the people around him are puzzled, and Peng Hu did ask questions directly, on the surface, the three of them all looked suspicious, but in fact, these three people all knew He Fei, whether it was He Fei's personality or his previous style, the three of them all understood without exception, at this moment, seeing that the young man just stopped Peng Hu from punching in and did not answer, in silence, Ye Wei, Peng Hu and Cheng Ying all had a tacit understanding and did not continue to ask, but instead stood in front of the machine with He Fei in a silent posture without moving.

During this period, Cheng Ying also observed the surroundings of the corridor while He Fei bowed his head and began to guard everyone.

Getting back to the point, let's not talk about what Ye Wei and the others were thinking for the time being, and not talking about how many people had doubts about He Fei's blocking Peng Hu from checking in, the reason why He Fei stopped Peng Hu was not that he planned to give up punching in, let alone found any dangerous anomalies, but from the experience before and after, from the reintegration of a series of experiences before and after in his mind during the process of going upstairs, after all, since entering this seemingly difficult ordinary task, He Fei's brain has never stopped thinking, let alone rested for even a second, It is for this reason that before making a certain decision, He Fei believes that it is necessary to be cautious!

And this so-called integration refers to the changes that have occurred during the entry into the mission world, including watch failure, mobile phone failure, time stop, Yao Fujiang exclaimed that there is a sting, and the events experienced during the power room, as I have said many times before, as early as the first car 1 After watching the video preview, He Fei has always been very concerned about this ordinary mission!

cares, incomparably cares, and the root cause of this concern comes precisely from the mysterious death of a middle-aged security guard in the video preview.

For the executor who is often struggling on the edge of life and death, it stands to reason that there is no need to make a fuss about the killing of the living by special means, after all, the ability of the mantis is strange, generally speaking, although the executor cannot deny that he must understand the mantis as much as possible in a task, but he is mainly committed to finding clues to obtain information, and he can find a way to survive with enough clues, indeed, this is true, this is true, but through this video preview He Fei faintly felt a feeling, which felt very peculiar, For the first time, he felt that the threat of death in this paranormal mission did not come from the mantis, but from the performer himself!!

Yes, this is what He Fei felt after watching the video preview, the video preview ended, and then everyone entered the mission world, and everything that happened next really revealed weirdness and many incomprehensible places everywhere, through some observation and analysis, he himself first found out the amazing phenomenon of time stopping, which had never happened, and then followed this clue to link the time stop with the punch card machine, and the time stopped inexplicably was a curse, and the task information had specifically mentioned the punch card machine, And the curse will never leave some meaningless words in the mission information, to sum up, since the mission information mentions the punch card machine, if you want to break the time stop, then find the punch card machine to test it, what if you hit the card can break the time stop? All of this is so plausible and logical, at least to others.

However, in He Fei's personal opinion, although all of the above is in line with speculation and logic, it is still not perfect, at least so far, no matter how he observes and thinks, there are a few doubts that he still hasn't figured out.

The first point, why did Yao Fujiang, who has lost his trace now, say that there are stalks behind everyone's backs? Since there are mantises, why would they not kill people when they are close to the executor? They were even allowed to run to the 20th floor in one go, and even went to the power room to restore the power of the building? Would the moth be so kind? Will the executor be so laissez-faire to move around the building with impunity?

The second point, what is the inexplicable uneasiness of Ye Wei when she is in the power room? Ye Wei herself couldn't give an explanation, after all, Ye Wei and herself at that time had the same thoughts, the logic was clear, and the clues obtained were indeed constantly refuting Ye Wei's sense of unease, and in the end, relying on the coin toss, everyone still chose to restore the lighting system of the building.

As for the last point

If the above two items can be temporarily put aside and temporarily suppressed on the grounds of priority breaking time stop, then this third point is precisely the real reason why He Fei didn't dare to punch in immediately after sorting out his thoughts!

Because, He Fei remembered one thing.

A cold memory that sent chills down his spine, that is, in the impression, in the original video preview, the middle-aged insurance officer died not long after swiping the card in front of the punch card machine!!

Why is it okay for a middle-aged security guard to walk down so many floors during the patrol? Why was he killed by the Black Shadow Attack not long after punching the card on the 20th floor?

Is this a coincidence? Or is it some kind of hint of the task?

Or rather

It's okay when you don't clock in, but once you clock in, it means that death is coming?

This is a creepy guess!

Let's not consider whether this is the case or not, once He Fei noticed this in the past, let alone being uncertain, he wouldn't even try.

At this point, some people may not be able to understand it, and they will definitely think of a somewhat contradictory question in their hearts, that is

Since He Feiming knew that swiping the card in front of the punch card machine was very likely to bring disaster to himself and even the entire team, why did he propose to go to the 20th floor to punch in when he was in the lobby on the first floor? Isn't this self-defeating? Isn't that inconsistent?

No, it's not contradictory, it's not contradictory at all, the reason is that even if he knows this, he knows that he has to take risks when he punches in, but he still has to do it when prompted by reality, he has to go to the 20th floor to check in without much analysis basis, even if he knows that punching in will bring danger to everyone, he still has to punch in!!

The reason is very simple, the curse will never leave some meaningless information in the mission information, once it is released, its information must have a lot to do with the task itself, yes, He Fei still clearly remembers that the mission information has separately mentioned that there is a punch card machine on the 20th floor, and the executor with a security identity can punch in front of the punch card machine, why? Why is this specifically mentioned in the mission information? And it's also the kind of plain information.,Non-mandatory information.,The task information just says that the security guard can punch in front of the punch-card machine.,But it doesn't stipulate that you have to punch in.,The charm of it is incomprehensible.。

As for He Fei, why did he have to try it when the task was not mandatory to punch in? The reason comes from the cessation of time.

Time has indeed stopped, it has really stopped, not only Hengfeng Building, but even the entire mission world is in a state of time stopping, if the failure of the watch and mobile phone alone is not enough to prove, then why has not found even the smallest time display device in the entire building from beginning to end? If that wasn't enough, then the moon and the clouds around it, which hadn't changed for a long time or even now, were the final proof.

What does it mean for time to stop? It means that this supernatural mission, which is ostensibly only for one night, will never end!

It is conceivable that the executors who are confined to the building by the rules in the state of time stop will not want to go out in this life, and the end will only be death, even if the mantis do not kill them, it will not be long before they, the executors, will still starve to death in this closed building.

Early death is death, late death is also death, doing nothing is an absolute dead end, but doing some attempts may still have a glimmer of life.

Yes, the above is the only reason why He Fei still proposed to go to the 20th floor to check in even though he knew that it would be dangerous to swipe the card, and it was also the only reason why the captain Ye Wei was willing to accept He Fei's suggestion after learning about his intentions.

Of course, if you say that, the truth is indeed the same truth, but when the matter came to an end, when Peng Hu was about to check in according to He Fei's logical analysis, He Fei, who was becoming more and more uneasy in his heart, still subconsciously stopped the other party under the impetus of fear, and instinctively stopped the other party from checking in.

He Fei knew that this card had to be swiped, but

But he was still afraid!!

"Whew"

Gradually, as he was silent for a long time, as he thought deeply, He Fei, who finally came to the conclusion that Ka Fei could not be brushed, was entangled to the extreme, perhaps because of his inner uneasiness or because he used his brain too much, He Fei, who was originally bowing his head and contemplating, suddenly showed a painful expression and let out a groan, and then slowly squatted down with his head in his hands.

No one expected that He Fei, who was fine just now, would react like this, seeing this, Ye Wei and Cheng Ying, who happened to be on the left and right sides of He Fei, hurriedly stretched out their hands, and both grabbed in front of He Fei's squatting body and supported the young man's shaky body at the same time, at the same time, two inquiries full of concern and even similar content also came straight from the mouths of the two:

"He Fei, what's wrong with you?"

"No, I'm fine."

Fortunately, He Fei's body is indeed fine, and the painful performance just now is just a stress reaction caused by the fact that he can't think of an answer, first he broke free from the support of the two while smiling bitterly, and then waved his hand to indicate that he was fine, and then, He Fei turned his head and looked at the wall again, throwing his eyes on the black punch card machine in front of him.

As mentioned above, He Fei is fine, having said that, when he noticed the young man's frowning and still slightly painful face, whether it was Ye Wei or Cheng Ying, the two could still faintly feel that the young man was very tired, very entangled, and even extremely hesitant.

Seeing this scene, the two of them inevitably had some different thoughts in their hearts, but unfortunately, it was a pity that they had no choice, or who among the few people present did not want to find a way to survive as soon as possible?

For a while, He Fei, Ye Wei, Cheng Ying, and Peng Hu all stood in place in a complicated state thinking about different things, and the atmosphere became more and more solemn, on the surface, everyone had miraculously not encountered any danger after entering the building for so long, but in fact

The more and more uneasy sense of crisis has intensified in the hearts of several people!

"Whew!"

In the end, under this dilemma that he was really not sure of but had to do, after another moment, taking a deep breath, He Fei's expression changed, and the original tangled and complicated expression was replaced by solemnity, gritting his teeth, he made the final decision!

The young man first took out a black magnetic card from his pocket that was exactly the same as Peng Hu's hand, and waited to scan the surrounding environment, and then glanced at each other with the rest of the people, and saw Ye Wei nodding, and then

He slowly pasted the magnetic card in his hand towards the punch card machine in front of him
