At the beginning of the war, our soldiers were often overwhelmed by the enemies who grew up in the rainforest because they had no experience in rainforest warfare. But this was the beginning, and later, as our warriors adapted to the rainforest climate, they were so brave that they chased the enemy like lost dogs. At the end of the fight, there are often entire formations of troops captured. But again, when I encountered a unit of the other party known as the "Rainforest Ace", the other party really had something. When the authenticity first started, this unit relied on its full understanding of the rainforest and superb skills, and made our soldiers suffer a lot. In addition to using all kinds of firearms and conventional weapons, they will also make a lot of traps according to local conditions, and these unbelievable traps make us suffer a lot. It's no wonder that most of the country is covered in rainforests, and these guys have grown up in the rainforests for a long time.

But fighting a war is not based on circumstances – it also depends on national strength.

These guys, who had been drilling in the mountains all day, finally provoked the commander of our army at that time, and he ordered the troops to be directly covered with heavy artillery, layer by layer, and under the threat of absolute firepower, these guys had to flee deeper into the mountains. The commander who led the team was ready to order his men to pursue, but the local guide said that this place must not be entered, and if you go in, you will not be able to get out - this is a local superstition, they say that there are monsters living in this ditch, as long as you go in, you don't want to get out alive, since they have run in, then let the monsters who live in this place clean them up - this is a typical feudal superstition.

However, the commander at that time was also very clever, and the feudal superstition was naturally unbelievable, but since they ran into this deep ditch, there was no need for them to pursue. Why drive them into a deep ravine, it's not that they can't beat people when they fight in the rainforest. If you give up the cover of heavy artillery and pursue it directly, if you are beaten out by someone at that time, won't it be a laughing stock?

So he gave an order for the heavy artillery to block the mouth of this ditch directly, and no one was allowed to come out.

The battle did not last long and ended in just half a year. The other party admits defeat, then we naturally don't have to block it anymore, this commander ordered his subordinates to shout into the valley, but who knew that after shouting for two weeks, no one came out. At this time, the local guide reminded the commander that they had been in for two months, and they must have all been killed by the monsters inside. Of course, the commander didn't believe this either, but he had already carried out the order to inform the people inside to come out and surrender, and since the other party didn't come out, then there was nothing he could do - of course, if it was according to the local guide, whether they were devoured by the serpent or had their lives taken by something else, there was no need to investigate.

If this is the end of the story, then this and that may be heard as a story, and what happens next is even more bizarre.

A few years after the end of the war, two soldiers of a certain unit of our army's surveyors also mysteriously disappeared as a result of transporting food through the Lost Soul. Two platoons were dispatched to search for the unit, but in the end they found nothing.

Next, a team of forest exploration and design of the local forestry department came to the Lost Soul Tai to survey and camped near the Guanmen Rock. Lao Chen, a tall technician with strong physique, and Xiao Li, an assistant, took the initiative to take on the task of breaking through the gatestone. The next day, they picked up their mapping bags, wrapped two steamed buns in paper and walked towards the gate stone. But in the middle of the night, there was still no sign of their return. From the next day, the search for the missing persons gradually expanded. A team of more than 100 people from the Forestry Bureau and neighboring counties to search for the missing people also arrived. They walked all over the green mountains and searched for the valleys, but except for the two pieces of paper used to wrap steamed buns, they never found any clues.

Had to quit the place.

Why are the fighters and forestry surveyors lost here?

Local villagers said that there is a high possibility that people and animals have gone missing and died in the ditch, and that it is very likely that they were caused by the fog. The Lost Soul Tai Forest Area is a primeval forest, there are more than 200 days a year are locked by dense fog, coupled with the steep cliffs in the ditch, there are many dark rivers, people who are not familiar with the terrain enter this deep mountain and wild valley, and if they are not careful, they will fall off the cliff, and the bones are incomplete.

Regarding the claim that the missing people are alive and dead, Mucuo, a local hunter, said that the missing people may have been taken away by fierce beasts in the mountains. The old man Mucuo also said that in the 50s and 60s of the last century, there was almost no way to go in the ditch. Most of the missing people came from other places, they were not familiar with the terrain, and there was no communication equipment at that time, so it was difficult to get out after getting lost.

It seems that there is a credible account of the disappearance. But another, even more bizarre case of getting lost makes people feel that the truth is not so simple.

In 1991, the local forestry bureau organized a team of nearly 20 people to enter Heizhugou to conduct forest resource surveys. In addition to the necessities, we are equipped with a variety of professional communication equipment. When the survey team completed its scheduled work and evacuated down the mountain, it encountered a rare heavy fog. Zhu Kaishuang, a survey and designer who entered the mountain at that time, still remembers the scene at that time. He recalled: At about five o'clock in the afternoon, fog rose in the mountains. Visibility in the forest is very low, so you can only rely on a map and compass to guide you to the way, but you can't find a way down the mountain. If you don't get help in time, you may never get out. It wasn't until I checked the map after going out of the mountain that I found that the road I took when going down the mountain was nearly 30 degrees off the correct route. The most surprising thing was that all the seven compasses carried by the expedition team were pointing in the wrong direction.

During the investigation, the scientific expedition team was surprised to find that most of the series of disappearances in Ecstasy Tai occurred in a place called Shimen Pass. So, what secrets are hidden in the vicinity of Shimen Pass, and why did the compass mysteriously fail here? For many years, people have speculated about the loss and disappearance of the Ecstasy. At the end of the 90s of the last century, some people proposed that there was a certain magnetic field in the Ecstasy, which affected the instruments carried by the people entering the mountain, so it caused many disappearances.

For this purpose, some experts have brought advanced geomagnetic detection equipment with them – they believe this claim.

The earth itself has a huge magnetic field, and the geomagnetic strength varies with the geographic latitude. The equator is the weakest and gradually strengthens towards the poles. There are many invisible magnetic field lines between the north and south poles of the earth, and it is because of the presence of magnetic field lines that the compass usually points in a fixed direction in the north-south direction. If the Earth's magnetic field changes, or if it is disturbed by strong magnetic ferrous elements, it will deviate from its original direction.

At the mouth of Heizhugou, a well-known scientific expedition team investigated the local rock formations. After on-site investigation, the expedition team came to the conclusion that the rock formations in the area are roughly divided into three parts, with the lowest layer being limestone, the middle layer being basalt, and the top layer being sandstone. Among these three layers, basalt is formed by volcanic eruptions, and the rock layers generally contain metallic elements such as copper and iron, which may produce magnetic field effects. However, as a rule of thumb, this magnetic field strength is very weak compared to the geomagnetic field and does not affect the compass deviation.

Later, they also put on special equipment.

Measured with a professional instrument, the magnetic strength measured at the mouth of the ditch is 49,400 Nat, which is within the normal range of values on this line of latitude. This shows that there is no anomaly in the geomagnetic field in this lost region. But why did the compass fail? In order to find out the truth, they decided to follow the route taken by the missing people in those years to go deep into the vicinity of Shimen Pass to investigate. Not long after the expedition team set off for Shimen Pass, the sky began to drizzle, and the fog in the mountains became thicker. The road washed away by the flash flood was very difficult to navigate, and the side of the road was a cliff, which made the expedition team members frightened.

On the way, a colored stone on the side of the road attracted the attention of the scientific expedition team.

Basalt in general is formed by volcanoes erupting on land, and there are a large number of pores. The basalt in this area is different, it is formed by volcanoes erupting from the bottom of the sea, and because of the rapid condensation, it forms basalt with a delicate texture and no pores. This rock formation is like a natural aquifer underground, holding the water and playing the role of a basin to hold and store water. A large amount of rainwater cannot penetrate and is confined to the root system of the mountain vegetation. The average altitude of this primeval forest is more than 2,500 meters. Due to the temperature difference between day and night, the water rich in vegetation is constantly evaporating during the day, and the temperature drops at night, and the moisture in the humid air condenses into small droplets, thus forming a fog in the dense forest.

The scientific expedition team advanced all the way, and after arriving at the Shimen Pass, everyone lost their way again.

Not surprisingly, this expedition team came out in disarray.

How to put it, they didn't analyze anything except the reason for the fog that was right and wrong. At that time, this well-equipped, advanced and well-prepared scientific expedition team failed to enter the exploration here, and there was no serious scientific expedition team to enter it. In the years that followed, there were reports of people going missing, but there were still some unsolved mysteries in the area.

"If there's really a reason for us to enter a parallel world, then I think it's probably because this place is inherently wrong. Li Huan remembered the legend about this place and said, but he turned his head and overturned his assumption: "But this is not right, if this place is so dangerous, then why do they want to lay a field track here? I still don't understand this legend, if even I know, then the local engineering troops must know very well, they lay the runway here, except for making trouble for themselves and making us unhappy, why not find another place?"

"You also said that this is a legend?" Xiao Fei understood now: "Think about it, you yourself say that this thing is a legend, so how much credibility does it have." For example, if you are an individual who goes out on an adventure, then you will definitely try to avoid such places. But if you think about the people who built the field runway here, it was a whole formed engineering unit. Among so many troops, I know so many troops, I have seen so many civilized troops, there may be a thousand differences in troops, but there is only one thing that is the same, that is, they only believe in their own strength, not in legends. ”

"You're right. Li Huan thought about it, Xiaofei made sense.

We are an atheistic country, which has developed from the past to the present, relying on firm materialist ideas to lead everything. What kind of legend or other nonsense may make sense to one or two scientists, but if it is a large army to carry out construction, no matter what legends and monsters you have - there are really demons and monsters in the way, and they will directly smash you.

Therefore, Li Huan felt that they should be the guiding ideology when they were building, as long as the plane could land safely, this was the goal of everything. In order to meet this goal, it is necessary to pick the place where it is most likely to land safely. And although this canyon is close to that terrifying Ecstasy Valley, where does the army believe you this?

In fact, before Li Huan became a cultivator himself, he didn't believe much in these evil things. But later, Li Huan himself became an unscientific thing, and he had to believe it. Therefore, Li Huan feels that there are indeed some mysterious things in this world, and these mysterious things cannot be said to be superstition. From Xiao Fei's point of view, it should be some kind of scientific phenomenon that human beings have never solved - if you want to say superstition, then Li Huan himself is the biggest superstition, and Xiao Fei's existence is also superstitious, what can you say, do you still tell people that there is an alien AI in your body?

That's the biggest superstition.

Therefore, Li Huan judged that the engineering unit must not have thought about the relevant legends when building the runway of the field airport, but only selected the most suitable terrain for construction, so how can this make sense.

Maybe something was triggered during their construction, maybe they liked that they were locked up in ~ parallel world, it was a matter of probability, or rather, Li Huan and their plane people were purely unlucky, God let them experience natural disasters, and after the hostages kidnapped the plane crash, they let them enter the parallel world, well, if they are so unlucky, then they should really burn incense after returning to China.

After ruling out all possibilities, coupled with the fact that this place originally had a "legend" history, Li Huan now can only believe that they have inadvertently entered a mysterious parallel world.

"Then what should we do now? How do we get out?" Li Huan had no choice but to accept this reality: "Is it like we are in Greystone Castle, we want to find some key thing to destroy or trigger?"

"That's different, it's artificially made. And this place, from your description, I speculate, should be a naturally formed rift, and after we met certain conditions, we were thrown into this parallel world, which is completely different from the last time. Xiao Fei said: "If you want to go out, you must first understand what a parallel world is." ”

The so-called parallel universe is actually an astronomical term. It refers to the parallel force universe, which is a pure elementary particle universe produced by parallel forces, and forms a multiverse theory with the universe of gravitational planets known to mankind. So the multiverse contains a universe of different interactions. The multiverse represents a collection of infinite or finite possible universes of diverse and different interacting forces. It includes everything that exists and can exist: all the different interacting forces, space, time, matter, energy, and the physical laws and constants that describe them.

In the 50s of the 20th century, some physicists discovered four known interaction forces when observing quantum. And since all matter in the universe is made up of quanta, these scientists speculate that since each quantum produces different interaction forces, it is possible that the universe is not just one interaction force, but is composed of multiple very different interaction force universes. The concept of parallel forces in parallel universes is proposed thanks to the fact of different interaction forces in modern quantum mechanics, especially the gravitational universe that is directly opposed. Among these universes, there are universes that are born under the same conditions of interaction forces as our universe, and there may be planets that are the same as the planets inhabited by humans, or planets with the same history, and there may also be universes with unknown interaction forces that are completely different from human beings. In these universes of different interacting forces, things develop with different results: species in our gravitational universe are absolutely non-existent in parallel universes.

The parallel universe of parallel forces is the opposite of the gravitational planetary universe of human beings, and the parallel forces neither coincide nor intersect, which can be described as "well water does not interfere with river water", resulting in a pure elementary particle universe, which is just opposite to the pure planet of human gravitational universe.

Some scholars use the analogy of parallel universes when describing them, they may be in the same space system, parallel forces moving in parallel, like two trains speeding on the same railway line, they may be in the same time system, but the space system is different, like a car driving in the upper and lower passages of an overpass at the same time - according to Xiao Fei, this concept has long been proposed in their world, and they have even begun to use this concept for space travel.

On Earth, however, the concept has only recently been proposed.

Since the 20s of the 20th century, many physicists have described the state of microscopic particles in quantum mechanics as a wave function. When a microscopic particle is in a certain state, its mechanical quantities (such as coordinates, momentum, angular momentum, energy, etc.) generally do not have a definite value, but have a series of possible values, each of which appears with a certain probability. That is, the motion of microscopic particles is uncertain and probabilistic. The wave function describes the probability of the spatial distribution of microscopic particles.

The well-known "single-electron double-slit interference" experiment in physics is the embodiment of the uncertainty and randomness of the motion of microscopic particles. In this experiment, a single electron interfered after passing through a double slit. In classical mechanics, an electron can only pass through one slit at the same time, and it is impossible for it to pass through two slits at the same time and interfere, whereas according to quantum mechanics, the state of motion of an electron exists as a wave function, and it is possible for an electron to pass through both this slit and that slit at the same time and interfere. But when scientists try to determine which slit an electron passes through through an instrument, they will always find only one of them. Neither instrument can detect electrons at the same time, and electrons can only pass through one slit at a time. Physicist Bohr proposed the famous "Copenhagen Interpretation": when people are not observed, there is a probability that the electron exists at both slit positions, but once it is measured, for example, the electron is measured at the left slit, and the electron has an accurate position, the probability of it at that point is 1, and the probability of the other points is 0. That is, the wave function of the electron "collapses" to that point at the moment it is measured.

Bohr introduced the observer and his consciousness into quantum mechanics, relating it to the state of motion of microscopic particles. but

The explanation of the observer and the "collapse" is not very clear and convincing, and has been questioned by many scientists. For example, how collapse occurs, whether it happens in a split second, or does it not start until a photon enters a person's eye and triggers an electrical impulse signal on the retina.

Based on this experiment, a man named Everett came up with a bold idea: if the wave function does not "collapse", it must increase linearly. In other words, the electrons in the above experiments are still in a superposition state of the left/right slit even after re-observation. Everett further proposed that people's worlds are also superimposed, and when electrons pass through the double slit, it is not only the electrons that are in the superimposed state, but also the whole world. That is, when the electrons pass through the double slit, two worlds are superimposed, and in one world the electrons pass through the slit on the left, and in the other world, the electrons pass through the slit on the right. In this way, the wave function does not need to "collapse" and randomly choose left or right, because it appears as a superposition of two worlds: people living in one world find that electrons pass through the slit on the left where they are, and in the other world, people observe electrons on the right. In the case of "Schrödinger's Cat", Everett points out that both cats are real. There is a live cat and there is a dead cat, but they are in different worlds. The question is not whether the emitting atom in the box decays, but whether it decays and does not. When the observer looks into the box, the world splits into two versions of itself. The two versions are identical in all the rest of the way. The only difference is that in one version, the atom decays and the cat dies, while in the other version, the atom does not decay and the cat is still alive. The two worlds of "the atom decays and the cat dies, and the atom does not decay and the cat is still alive" will evolve in parallel and completely independent of each other, just like two parallel worlds. Quantum processes create "two worlds", which is Everett's avant-garde "many-worlds explanation".

The advantage of this explanation is that the Schrödinger equation always holds true, the wave function never collapses, and thus it simplifies the basic theory. The problem is that the assumptions are too bizarre and the price comes from the fact that these parallel worlds are all equally real. It is no wonder that it has been said: "In the history of science, the many-world explanation is undoubtedly the boldest and most ambitious theory ever proposed." ”

Here are chapters

"Now that it's determined that this is a parallel space, we have to find a way to get out of it, but the question is how we got in, and I'm still in this problem, if we want to find a way out, we must first find the reason for getting in. Li Huan scratched his head: "When we landed, did you find anything abnormal?"

"No, if there was something out of the ordinary, then I would have found out a long time ago. Xiao Fei replied very quickly: "If you want to find out that something is wrong, it is better to go out and take a look yourself, and you are not alone now, you have to remember that the people on this whole flight are almost unable to resist." Even if you want to go out yourself, you still have a question, how do you explain to them the truth about the current situation, or do you want to make up a reason for them to wait here in peace? Anyway, in this case, I don't recommend that you take them out with you, it's better to go out and see what the situation is. ”

"If I take them out, then I'm crazy, I don't know what's going on outside, isn't it death to take them out? Li Huan sighed: "As for what the situation is, I don't think there is any need to hide it from them, after all, I have experienced so many things, and my nerves are thick enough." If I hadn't experienced anything at first, I'd have been hiding it from them. But now I think they're entitled to know everything...... And maybe someone else can give you advice. ”

"Go your way. Fei said.

After Xiaofei finished speaking, Li Huan took off the headset hanging on his ear, and after he once again confirmed that he could not receive any information, he organized his language and prepared to tell everyone about it. It's like Li Huan himself said, now that the crew has experienced all kinds of things, their nerves are already extremely thick, and they can accept this fact. And Li Huan felt that if he wanted to get out of this parallel space, he would definitely have to go out to see the situation, and if he didn't tell them the truth, it would be even more dangerous. God knows how bold these guys who survived the catastrophe kidnapping and plane crash will be. If you get out of the cabin while you're not there and get lost in the fog, you're really done. After all, I finally returned to my own country and stood on my own land, and I have experienced such a series of dangers, and only this last tremor remains...... If something happens at this time, then Li Huan will feel embarrassed.

Thinking of this, Li Huan got up from the driver's seat with repeated thoughts, and then walked to the cabin.

The excitement on everyone's faces in the cabin was palpable, and they were whispering to each other in celebration, discussing what they should do when they got home safely. Li Huan even heard some people say that this thing was written into the movie highlights - this idea is really awesome, the general movies are good-looking, if this matter is added to the movie tidbits, then it is estimated that the movie will be finished in the end, and there will be a large number of people in the screening hall who are reluctant to leave......

Everyone was excitedly talking about the next arrangement, and after seeing Li Huan walk out of the cockpit, Liu Qianhuan stood up and applauded for the first time, and under his drive, soon, warm applause filled the entire cabin, and even whistles and screams sounded one after another.

"The boss came out, and everyone applauded the boss! Oh my God, boss, this is definitely the most exciting thing I've experienced in my life. Anyway, I haven't experienced the exciting experience that has only been seen in this kind of movie so far, and the most important thing is to let us come back alive!

"Brother Huan, you are my idol! You are my idol in this life, this matter will not change, no matter who I meet in the future, you will always be the first!"

"Boss, I'll discuss something with you, can you open the cabin now and let me go down, I'm the photographer in this setting group! That's it, I see a thick fog outside, this situation is too special, this kind of white fog of the same concentration of milk, maybe ordinary people can't see it in a lifetime." There's exactly one scene in our movie, and I'm going to fill it up here, so we can start editing right away when we get back and don't have to waste a little time. ”

"Boss, what are we going to do next? Do you think we have to wait for someone else to save us?"

When they saw Li Huan coming out of the cabin, everyone almost cheered and applauded Li Huan with the sound of overturning the cabin. Their rebirth after several catastrophes was due to Li Huan's proper operation. When the plane that was almost out of control landed safely on the runway, although the situation around the runway was a bit weird, it finally fell from the sky, which proved that everyone was safe. When Li Huan was in the cockpit, everyone didn't dare to disturb him, because they were afraid that he still had something to contact and something to communicate with the outside world.

"I want to tell you one thing, maybe we are not out of danger yet. Li Huan listened to the tide of applause and cheers, and sighed.

As soon as Li Huan said this, everyone was shocked, and the cabin suddenly fell silent - but unlike the previous times, this time when Li Huan said that everyone's danger was not over, everyone just looked at Li Huan quietly, waiting for his next explanation. Because after a few things, everyone has completely believed that their boss is capable of handling all problems - the people in the entire cabin firmly believe that no matter what difficulties they encounter, as long as Li Huan thinks about it, it will definitely be able to bring everyone out of danger.

"We did land safely, and when we landed safely on the runway, I thought so, and I wasn't talking about the danger of our own existence, but that we were probably experiencing a joke of nature. After Li Huan organized the language for a long time, he finally said his guess.
