Cyber Heroes

When Xiangshan announced his retreat, Yuki and Hara Wenren were preparing for their next trip.

The original reporter has no short-term goals recently. The senior who did not want to be named was highly skilled and willing to spend energy teaching others, so she planned to follow him in the near future.

And the old-timer’s next goal is to head south. Generally speaking, when a knight goes south in the New World, there are only two final destinations - Paradox City and this Paralympic Games.

If the old man's goal is really these two places, then as a knight, Yuan Wenren feels that he should also contribute.

And Yuki is staring at the 3D printer.

With an isotope battery providing stable energy, this 3D printer captured from Z Organization can finally work continuously. Sometimes, Yuki and the others will also start other equipment in the car. At that time, the battery power supply was somewhat unable to keep up. But during this period, Yuki and the others will choose to temporarily shut down the 3D printer to allow the equipment to cool down and avoid damage due to excessive operation.

At this moment, these 3D printers are repeating operations quickly. They spray a layer of metal powder on the chassis, and then laser, magnetic field and ultrasonic waves immediately follow. The former heats and the latter interferes with the growth of the crystal. After this layer is quickly cooled, the machine will spray a second layer of metal powder. Repeat this, and within ten seconds, a batch of different types of metal parts will be produced.

After a batch is completed, the 3D printer's internal magnetic field changes, gathering the parts together and sending them out of the protective gas-filled chamber from a specific exit.

At the hatch, there are other robotic arms waiting. They quickly sort the parts and then perform preliminary assembly.

These robotic arms are also made with 3D printers.

At the beginning of the 21st century, Xiangshan believed that 3D printing technology was likely to change the situation of the entire industry. This was because as long as there were design drawings, a mature 3D printer could produce almost all types of appliances. As long as the first assembly machine is manually assembled, production can continue continuously.

The blueprint is just information. If intellectual property rights are not considered, downloading a design only involves the transfer of a few electrons - which requires only a small amount of energy.

Xiangshan couldn't remember whether he had realized his ideal in his youth, but now, he did have a design in mind.

The parts now produced by 3D printers are very small in size. When combined, they are only about two or three centimeters in size.

"Such a small thing, I really don't know how to fight..." Yuki whispered to himself.

"Huh?" Yuan Wenwen took a look and said, "Ah, microscopic insects. This is a way to confuse the enemy..."

Youki was stunned: "No one would target these little robots, right? Even if they carry high-explosive bombs, it would be difficult for them to hurt humans."

He didn't know what a "bug" was. He hasn't seen bugs since he was a kid, so he just calls them "little robots."

Yuki followed Xiang Shan to fight several times. Although Xiang Shan never let him go to the front line in a real life-and-death battle, he also witnessed the battles between Xiang Shan and Green Forest several times. In addition, Xiangshan will also give him some video playbacks of the battle.

He also has a general understanding of the power of explosives. Except for the "nuclear bombs" that Master said, there are very few explosives that can burst out the energy of this size to harm a fully cyborg warrior. In order to prevent knights from acquiring radioactive elements, the government rarely uses nuclear bombs, let alone equips drones with micro-nuclear weapons.

In Yuki's opinion, most of the things that can attract enemy firepower should be obviously threatening targets like drones with a diameter of about one meter.

The original reporter smiled and said, "Does the paper plane look threatening?"

The original informant has not actually seen Xiang Shan use paper airplanes, but she was present when Xiang Shan shared some combat experience, so the original informant knows that the "old senior" is good at paper airplanes. In addition, the paper airplane tactic is also an assassination method created by the legendary Wu Zu. Of course she gave this example.

Yuki fell into deep thought: "The paper airplane is used to make the radar misjudge... Does this thing have the same function?"

Using metal foil to jam radar is actually a very old tactic.

As early as World War II, when the United Kingdom faced off against the Third Reich, the United Kingdom would let aircraft drop large amounts of metal foil to interfere with radar.

In more modern air combat, pilots will rely on infrared jamming bombs filled with magnesium powder, nitrocellulose, polytetrafluoroethylene and aluminum foil to escape the lock of the opponent's missile.

The "paper plane" is essentially a way to make metal foil stay in the air longer and move faster. This is to make the foil combat method more suitable for modern cyber martial arts.

Mounting Longbo lenses and infrared emission devices on paper airplanes is also an extension of this tactic.

"Actually, paper airplanes can only be regarded as a 'stopgap measure'." The original source sighed: "The performance of this thing is not as good as more advanced jamming means, but it is simpler and cheaper. It can only jam Radar is an active detection instrument, so it is only used in situations where vision is difficult to play a role.”

Youji said: "For example, Tiehua..."

The original news person raised his forehead and said: "Indeed, such as Tiehua... But I want to say one thing, Tiehua is not a high-end smoke bomb. This thing is not particularly used in situations that interfere with vision."

Yuki was shocked.

Because he felt like his master had been using this thing as a smoke bomb.

The original informant was silent for a moment after hearing Yuki's doubts.

"Probably because you haven't attacked a truly heavily guarded base...the kind with ground-based radars." The original source said: "If it's just Tiehua and metal foil, the radar is not impossible at close range. Use great power to burn it through. Don’t doubt it, those hawks and dogs are not short of energy, and they don’t care about resources.”

Yuki felt that the world view he had established was challenged: "Isn't this... so it's used like this?"

"Seniors really like to use it this way...but in fact..." the original news person thought for a moment: "The more commonly used situations are to refract laser light, destroy electronic components and resist electromagnetic pulses. Blocking communication and interfering with vision are relatively minor. The function you want.”

Having said this, the original reporter suddenly realized that something was wrong.

If the Tiehua spreads, it will not only affect the enemy's communications, but also affect the use of one's own internal power, blocking hacking methods such as witnessing in battle.

Therefore, knights who are not very strong in internal strength will use this skill to make up for their shortcomings.

And it is true that knights on earth rarely perform witnessing techniques on government targets, because King Agni stays in the earth-moon system all year round. If the hacked target has the authority to ask King Agni for help, then the knights will almost certainly He was counterattacked from a distance by this strong internal force.

However, the old timers used it a little too little. His habitual use of Tiehua means that in this person's habits, "exerting internal energy during fighting" is not a "common preference".

But the old man’s internal strength level is obviously very high. Judging from what he said, it was really extremely high - at least that's how the original reporter saw it.

——So what kind of enemy did the old-timer fight in the past?

The original reporter couldn't help but think.

"...Sister Yuan?" Yuki called.

"ah?"

"You haven't answered my question yet." Yuki said, "You said these things are also used for interference?"

The original news person nodded. She looked at the half-finished mechanical insects and said: "As you know, little brother, many knights will install radars in their bodies. Although in close ground combat, radar waves will be reflected by the ground background to produce clutter, but as warriors When flying in the air or moving at high speed relative to the ground, if the body is not specially processed for stealth, it is still easy to be locked by radar. Moreover, warriors with the support of excellent target filtering algorithms can also pick out suspicious targets from the ground echoes for identification. and tracking.”

Youki nodded: "Master has talked a little bit, but he didn't go into depth."

"Well, senior probably hopes that you can start from scratch, master the theoretical basis first, and then proceed step by step, so as to avoid detours in martial arts practice." The original informant nodded: "You probably won't need this knowledge at this stage, but speaking of It doesn’t hurt to talk about it.”

Speaking of this, the original news person felt a little envious.

Her master died in a government raid very early on. In order for her to blend in with the crowd, the master did not hesitate to expose himself. From then on, Yuan Wenren could only explore on his own through the teaching materials and online information left by the master.

This is actually not an easy thing. At the beginning of the 21st century, one can find all the teaching materials from primary school to university on the Internet, but few people can learn these on their own. Human thinking is acquired, and teachers still need to guide them to form an overall understanding of the knowledge in the textbooks.

To this end, Yuanwen also took many detours. Her internal strength is now slightly weaker than Cui Shi, a young knight from the Red Stone Sect who has not yet started his martial arts.

It is precisely because of this that she hopes to study with the seniors for a longer period of time.

Putting away these emotions, the original source continued: "Therefore, many warriors - especially those with prosthetic bodies that are capable of supporting high-intensity combat, often install radar warning devices in their bodies to detect in time the radar that shines on themselves. Waves. Sometimes, even before the party using the radar has discovered the target, the party being illuminated has already obtained the position information of the irradiator based on the signal characteristics of the radar wave."

"It's like playing catch in the dark when you were a kid. The one who can't control the glow is the first to be exposed. Is that what it means?" After Yuki finished speaking, he suddenly realized that those lives and memories were as long ago as a lifetime ago.

"Yes, yes, junior brother You, you understand very quickly." The original informant did not notice Youji's mood swings and continued speaking to himself, "Therefore, although we often watch duels between long-range warriors, It may seem like a simple result like "I fired and the enemy fell", or "Both sides fired, one hit and one missed", but in fact, before both sides fired, radar detection had already been carried out. There are countless ways to fight detection and counter-detection."

It's a bit like the chivalrous stories of ancient times. Two heroes often confront each other for a very long time, and then suddenly end the secret fight on the spiritual level, and the winner is determined by a sword.
