That was a memory that Xiang Shan didn't remember now.

In 2048, in a mountain in the Russian Federation of North Asia.

A woman pressed her hat and roared loudly, "Crane! I thought you were a positive person......"

"W-what-" David Klein, who had recently grown a beard, responded.

Because the wind is really a bit strong.

"I say! I! I thought it was going to be! You're one! Serious people! And the mountain kind! Fooling around! It's not the same! ”

"Hey, you're here! A little bit! Bloody mouth! The man also yelled, "Me! That's it! Serious! Research activities! ”

"You take it! Group's! Budget! Bought! This one! Institute! Then launch for the first time! Actually! Paper airplanes! ”

"Ah, I said you two are stupid......" Xiang Shan said, "Why don't you put on a soundproof helmet and communicate with electromagnetic signals......"

The three of them were in a huge wind tunnel at this moment.

This place is the aerodynamics research institute of the former Red Alliance, which has participated in the development of several generations of MiG fighters. This huge wind tunnel may even be the product of seventy or eighty years ago.

However, with the drastic changes of the 90s, this place gradually lost its vitality. The project was canceled and the researcher was withdrawn. Most of these staff members have left the country for the Republic or the United States.

This institute is just a skeleton.

And it's the kind that is clearly priced. Its nominal ownership has moved back and forth between oligarchs a few times for at least half a century.

It's just that its owner never thought to inject blood into this dead place

David Klein bought this place not long ago. It's only worth a few hundred million.

David Klein was fascinated by the obligations of human spaceflight during the Cold War. He had bought space shuttles built by the former Red Union but not launched, a large number of obsolete and abandoned aircraft, and satellites. In addition, he also used his contacts at NASA to buy many artifacts on the other side.

The engineer considers himself the hardcore spaceman on Earth.

Incidentally, Yagmov was also involved in many of these projects. Yagmov was extremely rejective of personal enjoyment, believing it to be a sign of decay. He hardly invests the dividends he receives in his life.

After this research institute was bought by David Klein, he quickly cleaned it up and even replaced it with some advanced equipment.

According to his own words, he could consider opening a private research institute here and doing something he wanted to do.

Today is the ceremony for the reopening of this research base.

However, the woman never expected that the first project proposed by this brain-pumping guy would actually be......

"Paper Airplane Contest!" She was forcibly put a helmet on her head by Xiang Shan, and then continued to mumble, "Have you ever considered that this huge wind tunnel, due to its old design, the efficiency of energy utilization cannot be compared with the latest technology at all!" When turned on, it consumes a lot of power! What the hell is the paper airplane contest? ”

"'Items of personal interest'." David Klein shrugged: "And there's nothing wrong with that. This research team is something I just dug up, and it still needs to be run in. At this time, of course, it is important to do something interesting but not complex enough. ”

And Xiang Shan silently added in the back: "And what man doesn't like paper airplanes?" ”

"Huh? No matter how you look at it, it's a waste of luxury! We should be wary of this ......"

"No, you're wrong, Zhu." David Klein shook his head: "Humans know almost nothing about fluid mechanics. Let me tell you this, until now, human beings have only known that "airplanes are made to fly", but there is no exact answer to "why airplanes can fly......"

"It's not that Bernoulli's principle ......"

"That's one aspect at best, and it only says 'where the lift of the wing comes from', not 'why this whole can be balanced in flight'. Maybe the paper airplane in our hands can help us summarize some great theorem or formula. ”

"It's sophistry!"

"Alright, okay, dear." Xiang Shan pressed the woman's shoulder: "Aren't you having fun yourself?" As someone who works with pure numbers, you probably don't understand the fun of this kind of engineer! Come, let's get some metal foil to fold a paper airplane. ”

"Oh, we're all big."

"The thickness of the metal foil can't support it!"

It is rumored that this "paper airplane movement" has continued in this institute for more than ten years, and there are a large number of papers every year.

And those who are lucky enough to participate in this sport will naturally know a lot about paper airplanes.

It's better to say ......

"No one knows paper airplanes better than I do." Xiang Shan was so confident that he folded a small paper airplane with metal foil.

His prosthetic hand is very flexible. Such a complex three-dimensional structure may take tens of seconds in the hands of a normal person. But in his hands, it doesn't take a second.

Then, Xiang Shan threw these paper airplanes out with a hidden weapon.

This is already the third batch.

The paper airplane spun and flew like a dart – in fact, it was indeed metal. After a few seconds of flight, it unfolded thanks to the alloy's memory ability, and flew smoothly in mid-air.

Just now, there was an explosion in this hall. Although the blast has largely subsided, the blazing air in the blast is still slowly rising. The hot air held the paper airplane and rose again.

Then, it was locked by the radar.

At the beginning of the 21st century, stealth fighters generally had two ideas. The first is the use of high-tech coatings, which absorb the electromagnetic waves emitted by the radar. The second is to change the reflection of electromagnetic waves by relying on shape.

This is also the same as the appearance of some advanced fighters is very unconventional and counterintuitive. Because the electromagnetic waves reflected by him in the special frequency band are very special. To the naked eye, this is a behemoth with a length of several meters, width and height, but in the perception of radar, the electromagnetic waves reflected by this thing "look" like a bird.

Xiangshan just did the opposite.

This paper airplane is only the size of a natural person's palm. But if the proofreading is appropriate, then in the eyes of the radar, its reflection image is like a prosthetic person.

Of course, the scope of application for this thing is actually very narrow. If the other side uses not only microwave radar, but also visible light and infrared, then these paper airplanes will go bankrupt in an instant.

However, he knocked out the brightest visible light sources first, and then created scorching air by exploding, which is exactly what he did.

He disrupted the other distractions.

In this case, the enemy will probably set the AI to "fire if there is a problem with one detection method".

And this is how Xiang Shan probed the most responsive weapon system in the entire environment.

With a simple reflex speed, human beings can't keep up with intelligent weapons.

"Oops, oops, laser weapons." Xiang Shan said: "I really don't know if it's the misfortune of the knights, or my luck. Yes, the use of lasers here is also the right idea. ”

In contrast to live-fire weapons, lasers only need to be charged to be reused, and they do not riquil to cause secondary damage. If the target is a powerful martial artist, maybe the opponent can still rely on the unparalleled reflex nerve to dodge live ammunition, but the laser does not have this concern.

But foil airplanes are not only meager that will reflect radar.

It also reflects laser light.

Of course, due to the limited reflectivity, the metal foil cannot reflect 100% of the heat of the laser. If you really hit a laser, it will definitely evaporate.

However, for a few tenths of a millisecond before evaporation, it will still sputter laser damage.

You know, this is not the old generation of aluminum foil, but a real ultra-thin core, which is a great achievement of materials science in the new era.

If it is a natural person, this will cause the skin to burn or even die.

Of course, even in a prosthetic person, the fragile sensory parts such as the prosthetic eye can be damaged.

Flowers of high energy that only exist in an instant bloom in mid-air.

"What the hell are these idiot AIs shooting?" Bengel screamed, "Have they all been rewritten?" Who is the person debugging? Did he also collude with the knights? ”

"There is an upper limit to the precision of the prosthetic eye, and it is really impossible to see under this kind of strong light." Dai Jiutai said: "However, there must be a target, which is very small, but it can interfere with the judgment of the AI...... On top of that, it is bound to scatter electromagnetic waves. ”

The Apennines stood up. The food in front of him had been turned into char by the scattered mechanism, and it was really impossible to eat. The young master looked at the chaotic surroundings in confusion, not knowing what was happening.

And some of the ornaments on the ground were also lit by the mechanism, and the fire was everywhere. A warrior immediately picked up a fire extinguisher.

"Not good!" Dai Jiutai'a reacted "suddenly": "Your Excellency Bengel, his goal is to overload the laser generator!" The core crystal cannot withstand multiple consecutive launches! Make them stop! At least turn off the detection signal of the microwave radar! It is capable of scattering laser light, mostly on electromagnetic waves. ”

"Ahh Right! Bengel shouted, "Readjust the weapon AI!" ”

After a few seconds, the flash finally stopped.

But almost at the same time, several whistling sounds.

The laser emitters fixed to the walls and the dome exploded almost simultaneously.

Xiang Shanshan emptied the small missiles he had gotten.

When the frequency of the flash decreased, he walked in from the gate with more than a dozen paper airplanes.

He'd been modeling the atmosphere in that room, speculating on the direction of the paper airplanes, and then extrapolating back to where the laser weapons were based on the information the flashes were transmitting.

And now, one blow to the ground.

After twisting the necks of the two warriors beside him, Xiang Shan hummed softly: "Raise your head and look at the two vast ...... of heaven and earth"
