In the afternoon, the sky began to fall with goose feathers and snow, and the wind was blowing so hard that people could not even open their eyes.

Lin Feng walked around, and his mood was a little difficult to calm down. He always felt that there was something strange in this incident, but he couldn't say anything wrong.

Judging by the monitoring of the heavenly punishment system, the whole area is very quiet. The expected "biochemical army" did not appear, not even a single bird passing by to make soy sauce.

But it was this calmness that made him feel more and more irritable. And the closer you get to getting dark, the stronger this feeling of irritability becomes.

"Looks like it's going to be okay tonight. ”

He and Lin Yi sat on the snow outside, letting the violent wind and snow blow on their faces, hoping to calm their minds through the cold.

"Tell me carefully which direction those mutated pigs, dogs, and other things came from. Lin Feng asked casually.

"I don't know, it was already open when I arrived," Lin Yi returned, "and it was already dark at that time, the snow was falling heavily, and my vision was blurry." If there's anything out of the ordinary, it's that I feel like they're out of nowhere. When we cleaned up the site afterwards, we found that their tracks started in the col below, but then disappeared. ”

Out of thin air?

These four words made Lin Feng feel a little bad.

The biggest possibility of being able to appear out of thin air is the use of spatial teleportation. However, the space teleportation technology that can teleport living organisms is not so easy to master.

There are also such devices in the mall now, and the price is thousands of times higher than that of ordinary space teleporters, and the number of teleportations is very limited.

Can Ah San really master such a high-level technique?

It shouldn't be possible, if they really mastered this technology, I'm afraid it wouldn't be as simple as teleporting a few mutated creatures to the border.

Lin Feng never underestimated his opponent, but he also didn't overestimate his opponent.

But four words appeared out of thin air, and they still lingered in his heart for a long time and could not be dispersed. So he decided to go to the scene and maybe find something.

The two flew down the hill in a glider, and according to Lin Yi, the mutated creatures ran out of a small mountain pass.

But there is nothing else here except snow, and there are no imaginary caves or tunnels.

They landed on the ground, stepping on ankle-length snow and looking around.

"Do you think there's something wrong with this place?" After turning around, the strange feeling in Lin Feng's heart became stronger and stronger, but it was always as if it had not been pierced through a membrane.

"There's something wrong, but I can't tell. ”

Lin Feng stood motionless in the snow, but his mind was quickly analyzing everything he had just seen, and this feeling that he was only close to grasping the key was really annoying to him.

Lin Yi felt bored, turned on the strong flashlight and started searching again, looking at the series of footprints he left on the snow, Lin Feng suddenly slapped his head.

It's snow!

The snow in this col is so shallow that it can only cover the ankles, which is abnormal.

He immediately peeled off the snow and found that in addition to the relatively soft layer on the surface, the ice crystals had indeed formed more than ten centimeters below. Beyond the col, the snow here is at least knee-high!

What is it that makes the snow in the col less and thinner, and so large and so even?

Wind!

The strong air currents blow the snow away, leaving only the bottom part of the ice.

What could create such a strong wind in the col, Flying Machine!

The mutated creatures didn't appear out of thin air, but were transported by flying machines. But Lin Yi and the others did not find the aircraft, and they didn't even find the other party, which shows that the other party's aircraft is very advanced, can be stealth, and can deceive the radar!

Space teleportation technology is very high, but optical stealth technology is not a difficult task.

If this kind of aircraft, which cannot even be detected by radar and eyes, really exists, it will undoubtedly be a huge threat to Huaxia.

Ah San first conducted experiments on the border line to make sure that Huaxia's radar could not detect them, and then it was possible to make the next move.

It's really just a front to attract attention!

The other party's next step may be more drastic, but where will they put the mutant creatures?

Beijing, Shenghai, or any city in China!

Hundreds of mutated creatures suddenly burst into the crowd, and the panic caused by hundreds of mutated creatures alone is enough to cause chaos in a city!

Lin Feng calmed himself down, and he must not mess with himself at this time.

He first turned on the heavenly punishment system, let it search the entire airspace autonomously, and immediately warn if it found a UFO.

But this is probably useless, Lin Feng judged that when he used the Heavenly Punishment System to smash out that big pit here, it was still possible for the other party's stealth aircraft to stop in this mountain col to observe the situation, but he didn't find it at that time.

He immediately contacted Sima Lili.

"How do you mean how to crack a craft that can optically stealth and deceive all radars?" asked Sima Lili, "What are you doing now?"

"I don't have time to explain too much, you can help me figure it out. ”

"Well, it's actually pretty simple. "No matter what kind of stealth it is, it just can't be detected by our eyes or detection devices, but in fact it still exists in that place." So just fill that place with something else and we'll find it. ”

is worthy of Sima Lili, a word to wake up the dreamer.

Stealth is not disappearing, even a heavy rain, or a piece of gum, a stone, can make this stealth reveal traces.

It's just that Huaxia is too big, what kind of things can be used to quickly fill the airspace?

"I've thought of a way before," Sima Lili continued, "to release nanobots in the air, and they emit signals of a specific frequency between them, and once an unknown object breaks in, we can instantly detect them based on the fluctuation of the signal. It's just that this technology is too costly and too targeted to be popularized on a large scale, and later it was only used for special occasions. ”

Don't be afraid of high costs, as long as you can capture the opponent's stealth aircraft, you can research the corresponding cracking technology.

"I need some of these nanobots now, can we produce them ourselves?"

"The whole set of equipment is in the laboratory of the Academy of Sciences, and I can borrow it for you, but you have to pay for the cost of the nanobots. ”

Lin Feng flew directly to the Academy of Sciences, and in a well-guarded warehouse, he received this set of anti-stealth devices.

"It's better not to break it," said a gray-haired old professor, "this is the work of Academician Sima, and more than a billion yuan was invested at that time." ”

Looking at more than a dozen iron balls the size of a basketball on the ground, this is worth more than a billion, and it is really Sima Lili's style.

These iron balls are filled with nanobots, and as long as they are placed in a certain position, they can be dispersed into the air and then detect signals, which is quite convenient to use.

As soon as the device arrived, an alarm suddenly sounded from the Heavenly Punishment System: "Mutant biota found, number 5986, location, Linjia Village!"
