Under Li Huan's orders, most of them approached the bonfire and stopped moving.

When the plane landed, although everyone was very calm and had a very comfortable expression, they were actually scared in their hearts, because they had already gone through too many hardships, no matter how big and thick their nerves became, they were always under a safe environment, and any slightest wind and grass would make them nervous. Especially in this kind of room, where there is no darkness in the night, there is nothing to be seen on this makeshift airport except for a roaring bonfire and the light reflected off by the aluminum alloy shell of the aircraft.

The most terrifying thing is that apart from the sound of the machine cannon just now, not even a single bird call can be heard here. Human beings are essentially afraid of silence, afraid of darkness, and afraid of the unknown, and now these three things have been gathered, so everyone has to tightly surround the fire, looking for the most primitive sense of security of human beings - light.

Or there is another person who can give them a sense of security.

Now this person is sitting on the wheeled chariot, and he asks Xiaofei to import the fire control radar records of the wheeled chariot to see what the fire control radar has found. Before the communication was disconnected, Li Huan heard what Monk Chen said. In order to protect this important flight, there are a lot of weapons and equipment below to protect them at the temporary field airfield, and even the sky is blocked by fire control radar. The fire control radar of this wheeled infantry vehicle may have been set up a long time ago, and it will automatically scan for some high-threat things and shoot automatically - the problem now is that Li Huan doesn't know what it is shooting......

When Xiao Fei introduced the record of the fire control radar, Li Huan had already turned on his wild detection radar to the maximum range, and the two sub-planes had risen to the highest position and began to scan everything suspicious around. The fire control radar had already found something, but neither the Wild Detection Radar nor Xiaofei's sub-aircraft had scanned anything suspicious. Li Huan was unwilling, he even completely let go of his mental power, and slowly explored the suspicious things around him - but whether it was the wild poor detection radar, or Xiao Fei's sub-plane, or even Li Huan's mental power, it was still not suspicious at all.

Maybe after Xiaofei imports all the fire control radar records, he can find some clues.

"Did you find any suspicious records? I've been looking around now, but I still haven't found anything that would trigger the fire control radar fire...... It's weird, something that can trigger the design of the fire control radar must be a behemoth. It's impossible that I can't feel the size of a car, and that there is such a thing. Li Huan cautiously looked at everything around him, the thing that triggered the fire control radar shot just now, no matter what it was, was a potential threat in Li Huan's eyes, and he couldn't let this potential threat bring harm to himself or his crew.

"There is!" After three minutes of careful analysis, Xiao Fei suddenly popped open Li Huan's virtual screen, and at the same time, projected a radar onto the virtual screen: "You take a closer look...... About five minutes ago, the empty radar signal suddenly picked up a biological signal...... According to the records of the fire control radar, it was this biological signal that triggered the cannon fire. However, the creature only disappeared for a split second in radar range, so it only triggered a round of shots. It was so fast that it caught only a split second chance to fire. ”

"Biological signals!?" Li Huan was surprised: "Are you sure you say biological signals?"

"From the point of view of signal analysis...... This is indeed a biological signal, yes. Xiao Fei said firmly: "This fire control radar is still relatively advanced, and it can extract features from target reflection signals and clutter signals, such as extracting Doppler information, so it can analyze the nature of the specific target." ”

Today's fire control radar can easily distinguish targets.

Generally speaking, there is a system on radar called the radar friend or foe identification system, which is an electronic device used to identify the attributes of the target found by the radar. It consists of an interrogator mounted on a radar and an answering machine mounted on various aircraft, ships, and tanks. When the radar finds the target, the control interrogator sends out a signal, if it is its own target, the transponder on the target automatically sends out an answer signal, and the interrogator receives the signal and decodes it, and outputs the flag to the radar display to determine the target's friend or foe attributes.

As we all know, military radar is an important means of identifying friend and foe in modern warfare. According to the different loading positions and identification objects, it can be divided into ground identification system, which is used for the identification of aircraft, ships and tanks, airborne identification system, which is used for identification between aircraft and ground and surface targets, and shipborne identification system, which is used for identification between ships and air targets. They constitute a unified radar identification system for friend or foe on the ground, in the air, and on the water.

The radar identification system is composed of two parts: an interrogator and a answering machine, and the identification information is obtained through questions and answers. When the radar discovers the target, it controls the interrogator to send a set of password interrogation signals to the target. If it is your own target, the answering machine on the target decodes the interrogation signal and then automatically sends back the password response signal. After the interrogator decodes the response signal, it outputs an identification mark to the radar display, which is displayed together with the target echo to confirm that it is its own target. However, if it is an enemy target or a non-cooperative target, the code cannot be solved, and there is only a target echo on the radar display without identification marks. Because it uses the active question answering method, it can achieve a long range with a small transmit power and is not affected by the size of the target reflection area.

Of course, in addition to these fixed hard targets and the radar reflection characteristics recorded in the fire control computer, there are also some clutter - for example, living creatures, for example, some objects, can also be reflected on the fire control radar - for example, the fire control radar of this wheeled infantry combat vehicle can reflect biological information, and Xiao Fei will not admit it wrong.

"It's a biological signal. Xiao Fei said firmly again: "What should I do? Or is it a misjudgment of the fire control radar?"

"The probability of misjudgment is not high, I still believe in our own weapons and equipment. And whether it was a miscalculation or not, I'm going to go over and take a look. Now aren't we worrying about not being able to find a trigger point, or ...... This is the trigger point?" Li Huan thought for a while and said, "We may have thought in the wrong direction at the beginning, I think, we may be able to follow this clue and take a look." After all, we've looked at the process from circling to landing more than forty times and have found nothing so far......"

"What you said makes sense, then should we go over and take a look?" Xiao Fei also agreed with Li Huan's judgment.

"Go over and take a look!" Li Huan thought for a moment and slapped his thigh.

Next, Li Huan directly asked Xiao Fei to start the wheeled infantry chariot, and then drove to the side of the bonfire. At this time, all the people were waiting for Li Huan next to the fire, they didn't know why their boss wanted everyone to gather - anyway, when such an urgent order was suddenly given, there was always no good thing - especially when they saw this mighty wheeled infantry chariot driving over, everyone couldn't help but get nervous, after all, if there was no big event, why did you get this thing?

After seeing Li Huan driving this mighty chariot over, everyone turned their eyes on Li Huan, Li Huan jumped down from the car, thinking about how to explain to everyone what he was going to do next-after all, it can trigger the biological signal designed by the fire control radar, this kind of painting is scary enough at night, what can trigger the fire control radar to shoot, it must be a large creature, and it is larger than any creature known now - the family car is the minimum volume - But if you say this directly, you are afraid of frightening his own crew, after all, their nerves are already tense enough, if they suddenly hear a huge biological signal appear nearby......

Comparing his heart to his heart, Li Huan felt that he couldn't accept it.

Just when Li Huan was thinking about how to explain to everyone, Liu Qianhuan suddenly asked: "Brother Huan, have you found anything suspicious? Did something appear when our artillery fired automatically just now? You want to find the thing that the artillery fired just now, right?"

"Yes. Li Huan nodded, there happened to be a compliment

, Li Huan simply said his plan: "That's right, just now I repeatedly checked the fire control radar of that infantry tank, and I found a suspicious signal, so I am now going to see what the suspicious signal is coming from." Supposedly it's night, and I shouldn't have left everyone here, but we're in a parallel world right now, and this world isn't safe in the first place, and every minute you stay is dangerous. And you've probably seen it just now, and I've been thinking about it for a long, long time, but I can't imagine what dragged us into this parallel world. Since I can't find the answer, there are some anomalies now, and I think this anomaly may be the breaking point, so I'm going to go over and take a look...... Maybe I'll find the answer. ”

"Boss, what's the suspicious sign?" asked the girl in the cap who had the guts.

"It's some kind of mechanical signal...... Li Huan lied casually, he didn't want to scare everyone: "But don't be afraid that the signal only appeared for a short moment, so our infantry chariot only fired one round of shells and then stopped." I don't have any evidence, but I just think it's suspicious, and maybe it's the key to getting out of this parallel world. ”

After speaking, Li Huan added: "And you don't have to be afraid, I won't go too far, do you see it, I drove over this infantry chariot and parked next to the bonfire, and I turned on its automatic search and lock shooting function, after I leave, all of you get on the plane, if something appears, this wheeled infantry chariot will help you solve the problem - believe me, I am very sure that there is nothing in this world that can withstand the bombardment of this weapon." And, as soon as it fires, I'll rush back as fast as I can. ”

……

Although Li Huan didn't know what the reason was for them to enter this parallel world so far, Li Huan felt that as long as there was something wrong or suspicious about himself, he would check it, so he would always find the truth after a dozen times, and when he found the truth, he could take everyone out of this parallel world. Only after taking all of them out of this parallel world can this incident be perfectly resolved, and Li Huan himself is in a hurry - he doesn't think that there will be any threat to him in this parallel world, mainly because there are still things that threaten him in the real world, that is, his father and mother.

Li Huan confirmed that Yu Ting would definitely contact her father and mother first after returning to China and tell them what she had encountered in the Philippines. This matter is very nonsense, Yu Ting went back and told the second elder that she had encountered a hostage kidnapping incident in the hotel, and the second elder would definitely be worried that after the hostage kidnapping was resolved recently, Li Huan had not gone home yet, and there was a big problem with the plane...... This series of serial crises will make the second elder very nervous, if Li Huan doesn't rush back in the shortest possible time, explain all these things clearly, and let the second elder see that he is safe and sound, then Li Huan feels that his leg is almost impossible to save.

So no matter what, Li Huan must investigate this matter as soon as possible.

"Don't say that these staff are quite obedient, you just let them gather in the campfire team and hide on the plane when they are in danger, they are all on the plane now, and no one is outside. Xiao Fei said to Li Huan in the spiritual power channel: "When they poured it in, they also made the bonfire prosperous, I calculated, this bonfire is enough to burn for 7~8 hours, and the sky will be bright after 7~8 hours, you don't have to worry too much about anything." And isn't there a wheeled infantry vehicle left over there? I just adjusted its fire control system a little bit when I was reading the fire control radar data. The fire control system that I've tweaked will be more responsive and will be directly linked to me...... It's a peculiar feeling, and now it seems that there is only one fire control radar connected to me in the world, so you don't have to worry, no matter what happens, the first thing to pass is the strafing of that quadruple machine gun. ”

"That's for the best...... Are you sure it's going in this direction?" asked Li Huan.

"Determine the place where the radar has just strafed, and it is in this area, according to the radar strafing range...... Half a kilometre or so further ahead is where the anomalous biological signal appeared, but I'd advise you to be careful, as none of us have figured out what the hell is going on. Xiao Fei said: "Actually, only one sub-plane will affect my observation, do you want me to summon the other sub-aircraft as well? Anyway, there is a fire control radar on the other side of the plane, so there is no problem." ”

"It's good for you to keep a sub-machine and watch them, you don't have to summon them all, I'm scanning this generation with mental power now......" Li Huan shook his head: "There won't be any problems on my side, but I must take a good look at the situation over there, I'm afraid of encountering some tricks like diverting the tiger from the mountain, so one fire control radar is not enough." ”

"Okay...... Turn left, turn left, okay, this is the place. Xiao Fei saw Li Huan shuttling in the dense forest, and reminded Li Huan: "The abnormal biological signal that was scanned by the fire control radar just now appeared near here, you can look for the bullet marks here and see if there is anything strange." ”

After a wild run, Li Huan finally came to a gentle area in the middle of a dense jungle - this is the place where Xiao Fei had just found the abnormal biological signal according to the prompt of the fire control radar. However, no matter how fast Li Huan came, the sender of the abnormal biological signal had already fled, and he could only try to find the clues left by the guy who had just sent out the signal in this jungle.

Here, there are already thirteen kilometers from the improvised field runway.

Fortunately, Li Huan's physical strength has been strengthened by aura and nanorobots, and there is no problem at all in running 13 kilometers in a short period of time, otherwise if it were someone else, even if they saw this abnormal biological signal, they would spend a lot of time traveling through the jungle, resulting in everything that might be found being buried by the jungle - you must know that this is a primeval rainforest in the tropics, in this kind of rainforest, even the traces of an hour ago will be covered by those crazy plants and become the memory of nature. Therefore, even if the divorce comes here in the shortest possible time, he must carefully search every square meter of land around him.

But that's easier said than done.

"The rainforest here seems to be denser than the rainforest in the Western Ghats...... Li Huan said to himself, "It doesn't seem like there are any traces of huge creatures moving here...... Alas, I just asked Wangcai and Yu Ting to go back together, if Wangcai is still there, it can find out the clues for me immediately, after all, my nose is not a dog's nose. ”

Just in case it was just in the place where this signal came from at the beginning, he didn't think of how dense this rainforest was, and after he really walked into this rainforest, he left the improvised field runway that was built to land planes, and he realized that there are some rainforests in this world, which are not approached by humans at all, and then, Li Huan also understood one thing- Why are so many people lost in this jungle, maybe there is something strange about this jungle, but even if there are no such oddities, if you find a top explorer professional, he may be lost in this jungle.

The biological environment here is too complex.

The rainforest is a jumble of trees – some of which look like branches, but at first they are dry and slippery vines, like they have caught a snake. Running inside, buried deep in the shadows, in the dim light, just under the bushes, before anyone could be guarded, something jumped into the eye—and if you looked closely, it was some plant aerial roots that inexplicably arched out of the ground. Fortunately, you still think that because there is no life in this world now, there will be no abnormally dangerous animals in the voice, and if there are those abnormally dangerous animals, such as poisonous snakes and beasts, the danger level will be several levels higher.

Li Huan used the virtual screen to plan his own forward route, and he talked about the location determined by Xiao Fei, an area of nearly one square kilometer or so was divided into thirty small pieces, and they searched small pieces one by one, so that it was not easy to let go of any things and traces that might be found. But it's not easy, because the jungle is so dense that it bubbles up with a puff of fog and is finely fragmented

The plants are entangled, there is no grandeur of a big forest, let alone any elegance, and the unkempt stuffed green of the sea. Those vines swayed in the breeze, like silk flags, wrapped in a bunch by some force, wanting to unfold, invisibly bound by some kind of restraint, unable to unfold.

Li Huan quickly searched every square meter of this land, and he wanted to complete this search as soon as possible, because the longer he stayed here, the more uncomfortable Li Huan felt - this was not the jungle he was familiar with.

Li Huan is very familiar with these rainforests, of course, the density of trees here is deeper than that of the Western Ghats, but to be honest, this is still a rainforest. As long as it is a rainforest, Li Huan can easily deal with it, but he feels an unprecedented sense of crisis in this rainforest. Although he didn't see anything on the Wild Detection Radar, he always felt that something was peeking at him in the shadows. It was an intuition, a cultivator's intuition, and the cultivator's intuition was the most accurate, if he felt that something was peeping at him, then there must be something dangerous in the dark place, which was playing his mind.

In less than half an hour, Li Huan had completely searched an area of half a square kilometer.

"This ghost place is really something I don't want to see again in my life, why is there such a dense jungle, fortunately there are no creatures in this place, if I add some poisonous snakes and beasts, I will have a headache even if I am a cultivator now......" Li Huan scolded and prepared to continue to search in another grid, he complained while searching: "It's too difficult, I don't know what I'm searching for at all, if I know, where will there be such a square meter to find me and directly use mental power to detect." It's good now, I don't even understand, I wasn't so embarrassed in the rainforest before, why am I more embarrassed than before now that I've become a cultivator?"

"Don't be wordy, hurry up and find it!" Xiao Fei is also using the submachine to carefully search for an inch of space.

Of course, Li Huan just complained, because he knew why he was so embarrassed, and now the two are in a parallel world, and this world may be the same as the outside, or it may be different. So a lot of previous experience can't be used, at least Li Huan has accumulated those valuable experiences in the rainforest before, and he has been blinded here. The second thing is to search for something, the most important thing is to know the target of their search, and Li Huan and Xiao Fei don't know what they are searching for, they only have a vague biological signal, what characteristics will that biological signal leave behind, neither Li Huan nor Xiao Fei knows. The creature may have left a footprint, or a broken tree trunk, or a pulled vine...... Before seeing this anomaly, Xiao Fei and Li Huan didn't know what they were searching for, so both Li Huan and Xiao Fei felt very irritated now.

One of these two is a high-level cultivator, and the other is a super computer aI, logically speaking, as long as they know what they are looking for, they must be very fast in searching. But herein lies the problem, now they are complaining while scolding and searching, and after half an hour, they still haven't found anything.

"Do you think it could be that the fire control radar is a false alarm? I thought about it, it's possible, it's so far away, and the fire control radar is searching in the air, it must not be so sensitive to things on the ground, it may be a miscalculation. Li Huan finished searching a grid again, and began to suspect the problem with the fire control radar: "Otherwise, according to what you said, such a large creature will leave some traces no matter what! Don't talk about the rest, let's just say how it left this place! Look at the density of these trees, even I have to squeeze over, how did such a big creature leave here without leaving any traces?"

"I didn't tell you anything for sure, don't blame me, I'm just telling you about the Doppler signal found by the fire control radar, you can believe it or not. Xiao Fei said in the spiritual channel: "Of course, if you don't believe it, you can go back and look at the information left on the virtual screen, anyway, I think we have watched it forty or fifty times and haven't found the clue, so the problem must not be where we can see it." ”

"Didn't I just say that......" Li Huan sighed.

He himself knew that Xiao Fei's judgment was completely based on the misoperation of the fire control radar, and he fully believed in the sensitivity of the fire control radar, and there must have been something here, but he and Xiao Fei had not yet found evidence of the appearance of the creature—or rather, it was not a creature at all. If this is the case, then the difficulty of searching for traces will become higher, if it is a creature, Li Huan still has the confidence to find the clues he left here, but if it is not a creature, for example, if it is an object or something more dangerous, such as a soul life or something like that......

Li Huan suddenly snorted, he was startled by his own thoughts!

That's right, what is possible is a soul-state life, and if it is a soul-state life, all this can be said. When they were just in the camp, the soul-like beings crept into the nearby jungle and were locked on by the fire control radar, triggering the automatic fire of the machine guns. Soul-state life is invisible to ordinary people, but the nature of radar work explores the electromagnetic wave characteristics that can reflect objects - soul-state life can be explored in this way. If the fire control radar found this soul life, and then fired on the spot, and then the soul life was frightened and left here, leaving no trace, it would make sense.

But why is there a soul state life here, this life form is very unique, although Li Huan has encountered a soul state life, but it is also an extremely rare situation. However, the reason why Li Huan thinks this way is because he once encountered a divorce, and the place where life exploded - the most soul-like life was probably in the spatial crack of the Graystone Fort in the Mexican Kingdom, the point in time when it was frozen. There are a large number of soul-like beings on that side, so Li Huan has such an association.

That's right, since I encountered so many soul-state beings in the last parallel world, should there be some soul-state beings in this one? It's just that last time that space point was man-made, and this time it was mostly a prank of nature...... But since the nature is the same, maybe the things that exist in it are the same. And Li Huan has another reason to guess - you must know that the fire control radar of the current weapons and equipment is very advanced, and it is almost impossible to escape the pursuit of the fire control radar. Even if it is a fighter with a speed of about 2,000 kilometers per hour in the sky, it is impossible to escape the prediction and shooting of the fire control radar, let alone the "creatures" on the ground. Since the wheeled chariot has already fired, there must be some flesh left here.

Li Huan thought about it for a long time, he was searching for the grids he had demarcated, and he was thinking about this question at the same time, he thought about it, and felt that his conjecture was becoming more and more reasonable.

For one thing, you want to walk without leaving a trace in this rainforest - especially if it's a creature so large that it can trigger the fire control radar alert, and it's impossible to walk through this rainforest quickly without leaving a trace. And it's such a fast action, you have to know the speed of being able to escape from the fire control radar, it's definitely not low, with such a large size, such a fast speed through the rainforest, theoretically it is normal to hit a highway. But after Li Fang and Xiaofei, the two voice search masters, searched here for about half an hour, they still didn't find any traces, which shows that the creature that was huge enough to touch the fire control radar alert didn't even leave a trace, in short, it was evaporated from the world.

And not to mention the fire control radar, there is also Li Huan's mental power development here, as well as Xiao Fei's sub-machine scanning, Li Huan and Xiao Fei did not find any traces left by this guy, which can only show that it suddenly evaporated from the world.

Of course, there are no wonders in this world, Li Huan has always thought that the creator can endow many creatures with all kinds of strange abilities, even if they have such a large size, they can shuttle freely in the jungle without leaving traces, it is not that it is absolutely impossible.

But if you count another point, Li Huan feels that it is very likely that there has been a soul state life here.
