Busy, constantly busy.

In the blink of an eye, three days have passed.

Three days later, Eden Machining Sector, Research Room.

Richard stood in front of the console, his face could not hide his tiredness, but his eyes were sharp, staring at the five crystal balls on the console.

They were five crystal balls that he had made himself, and they were extremely rough compared to the ones Joseph had given them. The first is that it is more than a circle of size, like the head of an ugly baby. The second is that the layout of the magic pattern on it is very confusing, as if it is randomly put together.

But Richard looked at the five crystal balls and did not dislike them, but solemnly reached out and pressed them on the crystal ball on the far left.

The mana was injected in a specific order, and the three brilliances of "red, yellow, and blue" quickly appeared inside the crystal ball on the left, which lasted for two seconds and then slowly dissipated.

And at the moment when the brilliance inside the crystal ball on the far left disappeared, the other four crystal balls on the right "buzzed", and the brilliance appeared inside the brush, and it was the three kinds of "red, yellow and blue" - exactly the same, which lasted for two seconds, five seconds, ten seconds and twenty seconds respectively, and then dissipated in turn.

It worked!

When Richard saw the phenomenon, his eyebrows furrowed, and then his whole body relaxed.

Yes, it worked!

After three days of almost sleepless efforts, his research finally made the expected breakthrough, and he had made a preliminary crackdown on the Truth Society's communication crystal ball.

In other words: he now knows the simple principles of a communication crystal ball, and can use them to do something interesting.

Very interesting thing!

Thinking of this, Richard smiled. Walked to the side of the table, took out a new blank scroll, held a quill pen, and wrote as he thought, summarizing the research project.

......

"Rustling ......"

"Through a series of experiments, it is now almost certain that the Truth Society communicates with the crystal ball, relying on a special kind of energy wave to transmit information.

The mechanism is to input mana as an energy source, and through a specific magic spell, the energy is converted into energy waves, stored in a certain amount of information, and emitted.

The emitted energy waves are extremely penetrating and can pass over many obstacles and be transmitted to the receiving crystal ball. After receiving the crystal ball, it will decrypt and express the signal contained in the energy wave. ”

At this point, Richard paused his pen and thought of some doubts.

For example, the problem of the effective range of energy wave transmission.

He conducts experiments in the laboratory, which is almost face-to-face, and naturally there is no problem in transmitting and receiving energy waves, but it is different in the outside world.

The intensity of the energy wave emitted by the crystal ball is limited, and in the process of one-to-one propagation, the quality of communication will be worse the farther away due to the scattering and absorption of the medium.

According to the information he received from Joseph, the crystal ball not only supports one-to-one communication, but also supports one-to-many, many-to-many complex communication.

This is definitely not solved by relying only on the communication crystal ball of the terminal, at the very least, it also needs to have a signal transmission and processing center that plays a pivotal role.

In addition, according to Joseph, in any corner of the world, there is no barrier-free communication, and it is not easy to do this.

In a sense, this has already equaled the technology on Earth.

How does this work on Earth? This is done through dense signal transmitting stations on the ground and numerous communication satellites in outer space, forming a huge communication network.

In this world, there are no satellites, so how is it solved?

Richard pondered.

I couldn't get an answer after thinking about it for a long time, so I had to give up for the time being and study it slowly after that.

"Rustling ......"

Richard continued.

"The results of the seventh and eighth experiments show that the crystal ball transmits information and can be intercepted......"

Yes, the information of the crystal ball can be intercepted.

In a sense, the crystal ball is like a radio station on the earth, able to intercept the energy waves it transmits and get the information it transmits.

Of course, in order to really do this, you must know in advance the frequency of the energy wave emitted by the other party, and the precise time of emittion.

Then again, once intercepted, the intercepted information would be almost as plaintext as it would have to be deciphered, given the current level of communication of the Truth Society.

This is of course of little use at the moment, because he is in the Truth Society, and he can easily get the information he wants. But if you turn your face with the Truth Society in the future, then you can give the Truth Society a big surprise in this way.

Thinking of this, Richard subconsciously squinted his eyes, then returned to normal, and wrote again with a quill pen.

"Rustling ......"

"Through the tenth and eleventh experiments, conclusions can be drawn. The energy waves transmitted by the crystal ball can be interfered with by high-energy reactions.

Under normal circumstances, the crystal ball transmission has no effect. However, once there is a high-energy field around, the signal transmitted by the crystal ball will be distorted with a high probability, and the transmission distance will be significantly reduced. When the strength of the nearby high-energy field exceeds a certain value (Attach 1), the energy wave transmitted by the crystal ball will be in a state where it cannot be effected and will be blocked.

If the value of the energy field continues to increase, reaching a peak in a very short period of time (Appendix 2), unstable fluctuations will occur, and the fluctuation amplitude will exceed half of the peak, and the surrounding energy wave transmission environment will be seriously damaged, and communication will be completely impossible in a short time.

At the same time, in this process, if the communication crystal ball in the range is in working condition, it will also be seriously damaged, and the consequences include but are not limited to cracks, magic pattern burning, and partial crushing......"

After writing a long paragraph, Richard read it out of habit, his eyebrows suddenly raised, and he couldn't help muttering: "This seems to be a bit like an electromagnetic pulse." ”

Yes, it's a bit like an electromagnetic pulse.

Electromagnetic pulse, or EMP, is a special physical phenomenon. Generally, electromagnetic radiation generated by explosions, lightning, sunspots, conduit effects, or electrical sparks, or alternating electromagnetic fields that change violently with photoelectrons due to Compton scattering or photon scattering, are produced by acting on electronic materials, blasting equipment, or surrounding media.

The effective time of the electromagnetic pulse is generally no more than one second, and in just one second, any unprotected electrical appliances and anything connected to the wires, such as power systems, electronic equipment, microchips, etc., will be irreversibly and irreparably damaged due to the impact of the electromagnetic pulse.

In addition, electromagnetic pulses can cause drastic changes in the charge density of the atmosphere, causing severe interference in various wavelength bands below ultra-high frequencies, resulting in a complete interruption of communication for a period of time.

For example, if there is a large enough electromagnetic pulse in the center of a city, the entire city's mobile phones, computers, digital products, electronic devices, etc., will be burned instantly. Power went out across the city, cars rushed off the road because of damage to electronic systems, factories exploded because they couldn't control their reactions, victims went crazy because they couldn't communicate with the outside world, and the whole city was on the verge of collapse.

This is the electromagnetic pulse, this is the EMP.
