Optical reaction, also known as photochemistry, refers to the chemical reaction of a substance caused by the action of light, that is, the chemical reaction that occurs when a substance absorbs light energy under visible light or ultraviolet irradiation, such as carbohydrate synthesis, dye fading in the air, film Photosensitivity, etc., covers a wide range, mainly including photosynthesis and mapping.
Shadow is an optical phenomenon that belongs to mapping optics. It is a darker area formed because an object blocks the propagation of light. The prerequisite is light and object. Once generated, the object projection can be extended in the direction of light reflection.
The projection depends on the thing being illuminated, and all physical objects or living things can produce shadows, shadows, invisible substances, which can never be rid of.
When the light is sufficient, who in the world, whether human or other creatures, can get rid of their own shadow?
At this moment, the lights are bright, and the whole building is brightly lit.
After thinking about this, the man with glasses couldn't help but sweat profusely, and his already trembling body was shaken like chaff by the speculation in his mind. The only strange thing was that although he was shaking incessantly, he still didn't feel too big. action, but looked back again and glanced at the face in the eye shadow and observed the surroundings.
It is worth mentioning that, if you do not consider that the current task time is at a standstill, the bespectacled man's silence this time is really not short. He is currently observing the surrounding environment, his eyes scanning everywhere from time to time, observing all the scenes he sees.
In the field of vision, there was nothing special about the environment. Except for the fact that the floor space was clearly visible due to the bright lights, overall it was still a seemingly ordinary interior scene of a business building. After observing for a long time, Zhao Ping moved, and he had a new idea. He moved his legs and walked straight towards a room at the end of the corridor. Although the white door of that room had the same words printed on it as the surrounding offices, the words were not "office".
da da da da da
Hengfeng Building is indeed a tall building in the entire city. The height of 20 floors is enough to show that this building is extraordinary. The hard work pays off. Although I never dare to take the elevator, with the help of lighting equipment, the visibility is restored and the view is clear. After running for a long time, He Fei and the four of them arrived at their destination a few minutes later on just two legs, reaching the highest floor of Hengfeng Building, the 20th floor.
"Hoo! Hoo! Hoo!"
"Hoo, shit, is he really tired? Who is the idiot who built the building so high? I really want to greet his eighteen generations of ancestors now, hoho, hoho"
At this moment, with a series of rapid breathing sounds and Peng Hu's words full of dissatisfied curses, the four executioners who had stopped running and were collectively located at the 20th floor stairway were all panting and sweating. Peng Hu and Cheng Ying were fine. Even though the bald man cursed a lot, he could actually hold on despite being as strong as Cheng Ying. The curses he swore were just complaints. However, He Fei and Ye Wei were 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, running up dozens or twenty floors in one breath still makes them exhausted.
Because of this, if Peng Hu, who is physically strong, and Cheng Ying, who is in excellent physical condition, are just out of breath, then He Fei and Ye Wei, who have been running for a long time, are really sweating. They are currently holding one hand on the wall and the other. He leaned on his knees with his hands and panted heavily.
Of course, they were exhausted. The reason why they were willing to rush here regardless of their physical strength, and even rushed here without taking a rest in the middle, was still very clear about their purpose. Sure enough, after barely taking a breath, He Fei recovered for the first time. One walked towards the center of the corridor. Similarly, seeing He Fei making a move, Ye Wei, Cheng Ying and Peng Hu also followed him with the same purpose.
The next step was very simple. There was no need to even look for it. As soon as they arrived in the middle of the corridor on the 20th floor, everyone discovered the thing that 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 that was half embedded in the wall and half exposed appeared in everyone's field of vision. The machine was not big in size, and although its appearance was unusual, the machine in the center was obviously about the size of half a palm. The concave and convex grooves are enough to prove that this is a punch card machine, which is a working machine used by security personnel to prove the number of patrols. The middle-aged security guard in the video preview did indeed swipe his card on this machine before his death.
Seeing that the target was found, without waiting for He Fei who was watching the machine to make any move, Peng Hu immediately reached into his pocket as if he had some realization and began to rummage through his pockets. Not to mention, after this rummaging, the bald man He actually took out a magnetic card from his trouser pocket, a black magnetic card that looked like a bank card.
"Hey! I found it. The curse is not a lie. There is actually an extra magnetic card in my pocket. If my prediction is correct, I think this thing should be used to swipe the card in front of the machine."
While speaking, the bald man's hand holding the magnetic card subconsciously moved towards the card swiping port of the machine in front of him. However,
Snapped!
For some reason, just when Peng Hu was about to put the magnetic card in his hand on the machine, He Fei suddenly reached out and grabbed Peng Hu's wrist.
"Brother Peng, wait a minute."
"Huh? What's wrong?"
He Fei's blocking action surprised everyone present. After all, the purpose of the four of them coming here was to check in, and the purpose of checking in was to try to break the time stop. What's more, He Fei himself was the first to propose the check-in strategy, so When he found that he was stopped by the other party, for a while, not only did Peng Hu, who was stopped by the young man, look puzzled and asked, but Ye Wei, who had always acted calmly, and Cheng Ying, who was always alert during the mission, both cast suspicious eyes on He. Flying towards this young man who had been looking weird ever since he saw the machine.
It is true that most of the people around him were puzzled, and Peng Hu did ask questions directly. On the surface, all three of them looked suspicious, but in fact, these three people all knew He Fei, whether it was He Fei's personality or his past behavior. The three of them all understood without exception. At this moment, seeing that the young man just stopped Peng Hu from clocking in without any answer, in the silence, Ye Wei, Peng Hu and Cheng Ying all had a tacit understanding and did not continue to ask questions. Instead, they all responded in a kind of way. The silent posture was the same as that of He Fei, standing in front of the machine without moving.
During this period, Cheng Ying observed the surroundings of the corridor while He Fei lowered his head in thought, and began to alert everyone.
Let’s get back to the subject, let’s not talk about what Ye Wei and the others are thinking, and let’s not talk about the suspicions they have about He Fei stopping Peng Hu from checking in. The reason why He Fei stopped Peng Hu was not because he planned to give up punching in, nor did he find any dangerous anomaly. , but stems from the previous and later experiences, from the reintegration of a series of experiences and encounters in his mind during the process of going upstairs. After all, since entering this seemingly not difficult ordinary-level task, He Fei's brain has He never stopped thinking from beginning to end, let alone rested for even a second. It was for this reason that He Fei believed that he must be cautious before making a certain decision!
And this so-called integration refers to the changes that occurred during the period of entering the mission world, including the failure of the watch, the failure of the mobile phone, the stop of time, Yao Fujiang exclaiming that there were worms, and the events he experienced when he was in the power room. I have said this many times before. , as early as after watching the video preview in Car No. 1, He Fei was extremely concerned about this ordinary-level mission from beginning to end!
Care, unparalleled care, the reason why I care so much stems from the mysterious death of the middle-aged security guard in the video preview.
For executors who are often struggling on the edge of life and death, there is no need to make a fuss if a worm kills a living person through special means. After all, worms have many different abilities. Generally speaking, although it is undeniable that the executor must be in a situation as much as possible. During the mission, we learned a bit about the worms, but we mainly focused on finding clues to obtain information. If we grasp enough clues, we can find a way out. Indeed, this is true. However, through this video preview, He Fei faintly emerged. This feeling was very strange. For the first time, he felt that the death threat in this supernatural mission did not come from the monster, but from the executor himself! ! !
Yes, this is what He Fei felt after watching the video preview. The video preview ended, and then everyone entered the mission world. Everything that happened next was indeed full of weirdness and many incomprehensible things. After some observation According to the analysis, he first found out the astonishing phenomenon of time stopping, which had never happened before, and then followed this clue to connect the time stopping with the time clock machine. The inexplicable stopping of time was caused by a curse, and the mission information had specifically mentioned It has been compared to the time clock machine, and the curse will never leave some meaningless words in the mission information. To sum up, since the mission information mentions the time card machine, if you want to break the time stop, you should first find the time card machine and test it. , what if the time stop can be broken by punching in? It all seems so reasonable and logical, at least to others.
However, in He Fei's personal opinion, although all the above is consistent with speculation and logic, it is still not perfect. At least so far, no matter how he observes or thinks, there are several doubts that he still has not figured out.
First point, why did Yao Fujiang, who is currently missing, say that there was someone behind everyone's back? Since there is a wolf, why would a wolf not kill anyone when it is close to its executioner? They were even allowed to run to the 20th floor in one go, and even went to the power room to restore the building's power? Would you be so kind? Will the executors be allowed to roam around the building unscrupulously?
Second point, what was Ye Wei's inexplicable feeling of uneasiness when she was in the power room? Ye Wei herself could not give an explanation. After all, Ye Wei had the same thoughts as herself at that time, with clear logic, and the clues obtained constantly refuted Ye Wei's uneasiness. In the end, by tossing a coin, everyone chose to recover. Building lighting system.
As for the last point
If the above two points can be temporarily put aside and temporarily suppressed by the reason of giving priority to breaking the time stop, then this third point is precisely the real reason why He Fei did not dare to clock in immediately after sorting out his thoughts. !
Because, He Fei remembered something.
A cold memory that sent chills down his spine, that is, in the impression that in the original video preview, the middle-aged security guard died not long after he swiped his card in front of the card machine! ! !
Why is it okay for a middle-aged security guard to walk down so many floors during his patrol? Why was he attacked and killed by the Black Shadow Mantle not long after checking in on the 20th floor?
Is this a coincidence? Or is it some hint of the mission?
Or to say
It's okay when you don't punch in, but once you punch in, it means death is coming?
This is a creepy guess!
Regardless of whether this is the real situation, if it were He Fei in the past, once he noticed this, let alone being unsure, he would not even try.
Some people may not understand it at this point, and they will definitely think of a somewhat contradictory question in their minds, that is
Since He Feiming knew that swiping his card in front of the clock-in machine would most likely bring disaster to himself and even the entire team, why did he suggest going to the 20th floor to clock in when he was in the lobby on the first floor? Isn't this asking for death? Isn't this inconsistent?
No, it’s not a contradiction, not at all. The reason is that even though he knew this and knew that he would take risks by clocking in, He Fei still had to do it due to reality. He had to go to the 20th floor without much analytical basis. Try to punch in, even if you know that punching in will bring danger to everyone, you still have to punch in! ! !
The reason is very simple. The curse will never leave some meaningless information in the mission information. Once released, the information must be closely related to the mission itself. Yes, He Fei still clearly remembers that the mission information mentioned 20 times separately. There is a clock-in machine on the floor, and the executor with a security identity can punch in this paragraph in front of the clock-in machine. Why? Why is this specifically mentioned in the mission information? Moreover, it is a kind of plain information, non-mandatory information. The mission information only says that security guards can clock in at the clock machine, but it does not stipulate that clocking in is required. The charm of it is puzzling.
As for why He Fei had to try it when the mission was not mandatory? The reason comes from time stopping.
Time has indeed stopped, really stopped. Not only the Hengfeng Building, but also the entire mission world is in a state of time suspension. If the failure of the watch and mobile phone alone is not enough to prove it, then why is there no discovery in the entire building from beginning to end? A device that displays even the smallest time? If even this was not enough, the moon and surrounding clouds outside the window, which had not changed for a long time and had not even moved even now, were the final proof.
What does it mean when time stops? This means that this supernatural mission, which on the surface only has a time limit of one night, will never end!
It is conceivable that the executors who are restricted by the rules in the building when time is stopped will never want to leave in this life. The only ending is death. Even if the tiger doesn't kill them, it won't be long before they, the executors, will still be thirsty and hungry. Die in this closed building.
Early death is death, late death is death. Doing nothing is definitely a dead end. On the contrary, if you make some attempts, you may still have a chance of survival.
Yes, the above is the only reason why He Fei still proposed to check in on the 20th floor despite knowing that swiping the card would be dangerous. It is also the only reason why the captain Ye Wei was willing to adopt He Fei's suggestion after understanding his intentions.
Of course, that's what it says, and the truth is indeed this. However, when the matter came to an end, when Peng Hu was about to clock in according to He Fei's logical analysis, He Fei, who became increasingly uneasy in his heart, was still driven by fear. He subconsciously stopped the other party and instinctively stopped the other party from checking in.
He Fei knew that this card had to be swiped, but
But he is still afraid! ! !
"Woo"
Gradually, after being silent for a long time and thinking deeply, He Fei, who finally came to the conclusion that the credit card cannot be swiped, became extremely entangled. Perhaps it was due to inner uneasiness or overuse of his brain. He originally lowered his head and meditated. He Fei suddenly showed a painful expression on his face, groaned, 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 were just on the left and right sides of He Fei, quickly reached out and grabbed hold of the young man before He Fei squatted down. The bodies were swaying, and at the same time, two inquiries full of concern and even the contents were almost the same came directly from their mouths:
"He Fei, what's wrong with you?"
"No, I'm fine."
Fortunately, He Fei's body was indeed fine, and the pain he showed just now was just a stress reaction caused by not being able to think of an answer. He first smiled bitterly while breaking away from the two people's support, and then waved his hand to indicate that he was fine. Next, He Fei turned his head and turned his gaze to the wall again, to the black punch card machine in front of him.
As mentioned above, He Fei was fine. Even so, when they noticed the young man's frown and still slightly painful face, whether it was Ye Wei or Cheng Ying, they could still vaguely feel that the young man was very worried. Tired, very confused, even extremely hesitant.
Seeing this scene, the two of them inevitably had some different thoughts in their hearts. Unfortunately, it was a pity that they had no choice, or who among the few people present didn't want to find a way out as soon as possible?
For a moment, He Fei, Ye Wei, Cheng Ying and Peng Hu all stood there in a complicated state, thinking about different things. The atmosphere became more and more solemn. On the surface, it seemed like it was a miracle that everyone had entered the building after so long. did not encounter any danger, but in fact
The increasingly uneasy sense of crisis intensified in the hearts of several people!
"call!"
Finally, in this dilemma where he was really unsure but had to do something, after another moment, He Fei took a deep breath and his expression changed. The original complicated expression was replaced by solemnity. He gritted his teeth and did it. The final decision has been made!
The young man first took out a black magnetic card that was exactly the same as the one in Peng Hu's hand from his pocket. After scanning the surrounding environment, he looked at each other with the others and saw Ye Wei nodded. Next,
He then slowly put the magnetic card in his hand towards the punch card machine in front of him.
