From troll tribes to elf empires

Chapter 220 Application Development of Sound Waves and Volcano Exploration Team

Witch doctors have long ago discovered that they can give sounds various functional attributes by controlling the amplitude and frequency of sound waves;

And at the same time, they also learned from Warcraft spells and had the ability to create and receive sound waves in different frequency bands through rune spells.

After actual use for a period of time, they further calculated and further defined accurate values ​​for each frequency of sound waves based on vibration frequency and other indicators, and clarified the detailed relationship between various values.

Since then, the witch doctors have truly opened the door to research, and their understanding and application of the sonic field has gradually reached a stage that is completely different from the past.

However, the various theorems and axioms obtained during this period are really too obscure, and usually only witch doctors and witch doctor apprentices have the opportunity to actually use them when conducting academic research.

Therefore, in order to be popularized and to facilitate more users to have a general understanding of related concepts;

The witch doctors roughly and loosely divided them into twenty frequency bands from -10 to +10 according to the 'identifiable range'.

Among them, the natural vocal lines of trolls are between the -3 and +3 frequency bands, and because this range is the auditory recognition area of ​​most normal monsters and animals on the 'non-hearing side', it is defined as the 'normal band'.

However, the range of recognition by ordinary trolls' physical ears exceeds the upper and lower extremes of their own voices, reaching the -4 to +4 frequency band.

Therefore, the two wave frequency intervals above and below '-4' and '+4', which are outside the normal range but within the troll's hearing range, are separately defined as the 'troll special band', and each has its own application.

field of.

With the blessing of magic, it has been able to receive the '+-8' frequency band normally without any strange feeling;

The former is usually used between armies. It is the main method used by flag officers to convey commander's orders when conducting "short-distance direct audio communication" within ten kilometers.

In the early days, due to insufficient education and war demands, users of this type of totem were limited to witch doctor apprentices;

Since these four devices all use wave frequencies below '-4', the signals they send and receive are no longer supported and are directly understood by the brain in the form of 'recognizable audio'.

And if you continue to increase its intensity, it can also cause sound waves to propagate between "liquids with very small bubbles", causing the bubbles to shrink and expand, leading to violent explosions.

This is mainly because witch doctors have observed the strong penetrating power it exhibits when it penetrates solid and liquid matter, and when it carries a large amount of energy, it can also cause material particles to vibrate at high frequencies.

, thereby increasing the regional temperature.

These technical trolls are not witch doctors, nor are they apprentice witch doctors;

For them, with the blessing of spells and totems, they can indeed continue to extend the wave frequency acceptance range downward to extremely low areas;

Finally, there is another point worth emphasizing

Although advanced witch doctors can rely on their ‘ultra-low frequency infrasound’ reception ability to hear infrasound signals thousands of kilometers away;

But this does not mean that Nesta and the other four can effectively communicate from the east and west ends across the entire black forest.

Among them, the former has relatively concentrated applications in animal and plant medicine research, materials science exploration, etc. due to its good directivity, high interface wave mode conversion ability, and strong penetration ability.

As for the existing four advanced witch doctors, they are different in this aspect;

The recipients of the troll's voice message, even if they are in a non-blessed state, can use their own physical ears to recognize and directly hear effective information from the sound waves distorted by the magic within a certain range, and

No translation is required in between.

This is also proved by the elf girl;

The frequency band recognition range of her physical ears at this time has also reached the level of advanced witch doctors, within the range of -5 to +5;

On the 'audio application end', since ultrasonic waves are easily attenuated in the atmosphere, apart from the 'close range direct audio communication' that uses the 'Troll Special Band' as mentioned before, it is not better for the time being.

performance.

But with the blessing of their magical abilities, they can expand three frequency band levels beyond the upper and lower limits of the human ear, so that their sound signal reception range reaches the range of -7 to +7, and they still have enough brain power to

Parse out the part of the information you need.

Therefore, even if both the sending and receiving parties are blessed by spells and totems, the implementation of this plan has quite strict distance restrictions.

The application of sonic spells by witch doctors was actually later than the time when they had totem technology, so they were totemized soon after the spells were transformed;

Among them, 'medium distance' specifically refers to the transmission of acoustic signals within the '10-100 kilometers' section, which is mainly achieved using the '-5 level infrasound frequency band'.

Therefore, if you still want to use its characteristics to transmit messages, both the sending end and the receiving end need the assistance of corresponding spells or totems, and effective application can be achieved through the translation of the agreed code.

"I don't know, but what we are looking for is their boss. We can probably tell based on the size, right?"

Second, there is the gap in brain computing power;

From this, it can be judged that the corresponding structures in their bodies have not reached a certain level. This is the 'physical gap at the biological level'.

In addition, due to its high carrying energy and strong penetrability, there is a gradual trend towards killing in the future development direction.

However, in the more complex group casting mode, the breakthrough of the 'generating end' to the 'wave frequency above +7' is just around the corner;

Only when the frequency band was raised and lowered beyond '+-8', did she feel dizziness and other adverse reactions.

However, this is only because she is still in the growth stage and has not fully developed her physical talents. If she continues to grow according to this trend, she will gain corresponding abilities sooner or later.

If it is supplemented by magic, it can achieve full-band identification of the existing limit range. This may not be too rigorous.

In fact, when the witch doctors calculated the upper and lower limits of the sound wave frequency band, they used the recognition limits of Nesta and other four advanced practitioners with the blessing of magic to determine the value.

"Damn it. Is this guy the same guy just now?"

And of course they have become the backbone of the ruling government's Communications Department and the military command headquarters, undertaking corresponding high-level information transmission tasks.

These two comparisons have already made the difference in computing power quite obvious.

The only 'body size' factor that can be used for reference is just a guess based on the cave wolf, which is not necessarily rigorous in fact;

At least Azshara and the other three are now slightly smaller than ordinary trolls.

Although, the advanced witch doctors are still growing taller, among them Azshara, who was the earliest to advance, has become close to three meters tall again after so many years;

"It seems like I can't tell the difference between tut tut and tut tut. They all look exactly the same."

More specifically, the application of secondary waves is usually found within the four sound ranges: medium distance, medium long distance, long distance, and ultra-long distance.

The Communications Department needs to spend time measured in light hours and requires the hard work of a dozen technical trolls to calculate a set of information;

Witch doctors may only need ten lamp points to obtain the specific contents.

However, with the popularization of education and the continuous advancement of educational methods, more and more ordinary trolls have been able to learn professionally and have the ability to apply it.

Therefore, when the fanged witch doctor and Azshara went to the northwest mountains one after another, they could only communicate with the headquarters intermittently through the permanent signal relay station deployed remotely, and the sending and receiving process was abnormal.

of complexity.

It is a pity that Nesta and other witch doctors did not have the inspiration to develop a "combat power detector" similar to Dragon Ball, making this search somewhat inefficient.

As for the further downward fields of '-7th sound wave·long distance' and '-8th to -10th sound wave·super long distance', they are no longer within the reach of an 'ordinary brain'. They belong to the witch doctor and advanced fields respectively.

A special band that only witch doctors can 'use'.

Because only they have the ability to master the application methods in a short period of time.

Therefore, the witch doctors who observed this phenomenon thought that they could develop an 'ultra-high frequency sound wave technique' with enough lethality based on this, and then use this to carry out attacks.

It seems that within a few years, she will once again be on par with, or even surpass, her other compatriots in troll form.

The communication was smooth, but we encountered difficulties on the exploration side.

The creatures in the volcano do not seem to be within the range of the trolls' facial recognition capabilities. There is almost no significant difference between their lava-covered faces and bodies.

Let’s look at non-advanced witch doctors

First of all, there is no substantial gap between them and ordinary trolls in terms of ear recognition range;

Among them, the information transmission in the area from 100 kilometers to 500 kilometers, that is, the "medium and long-distance sound range" in the definition, needs to be achieved by using infrasound signals in the '-6' frequency band;

The signals in this range require more and more rigorously trained technicians, assisted by a series of complex calculation techniques, to filter out the complex signal background and parse out the part of the information they need.

, and further translate it into text.

Generally speaking, only witch doctor apprentices who have undergone specialized training, and some professional communications soldiers with extremely excellent professional capabilities, can be fully qualified for this job;

Third, there is a gap in knowledge reserves.

The "ability to recognize" that has been emphasized before actually refers to their ability to distinguish "background natural sounds".

However, the research on this technique is still in the experimental stage. Due to the frequency limit of the 'occurrence end', the witch doctors are not yet able to implement it;

The success of totemization has successfully allowed the users of this method to continue to extend downwards from the witch doctor level, giving it a wider range of usage scenarios.

In terms of feeling, this may be closer to the methods of "transmitting sounds into secrets" in Nesta's previous novels;

In the same '-7 infrasound' range, the recognition and analysis speed of advanced witch doctors is much faster than that of ordinary witch doctors;

In the same '-6 infrasound' range, the identification and analysis speed of witch doctors is also much faster than that of apprentices;

The southern end is pretty good. The southern part of the Black Forest is a vast desert area. As long as they bring sufficient supplies, the exploration department can basically set up signal relay stations there without any scruples to establish contact with the front-end exploration team.

;

But things are a little more complicated at the north end.

~~~~~

At this time, several groups of investigation employees have arrived at the volcano group and are conducting a thorough investigation of the creatures inside.

The non-early recognition areas outside of ‘+-4’ are named ‘super secondary waves’, and they also have their own application or focused development directions.

After advancing, their physical ear sound wave recognition range has been improved by 1 natural level respectively beyond the upper and lower limits of ordinary trolls, reaching the auditory recognition ability in the -5 to +5 frequency band.

And for the same information, Nesta and the other four might be able to analyze it in just a few minutes.

The members of the exploration team can only guard the crater one by one, waiting for the creatures inside to occasionally appear, so as to 'identify' them with the naked eye.

Nesta and the other four have inherited the extremely sensitive hearing system of the troll tribe;

When they advanced, they made another sublimation on the original basis, thus creating the difference between them and other trolls.

The reasons for these differences mainly lie in three aspects;

One is the difference in biological levels manifested in the physical body;

'Being able to hear' does not mean 'waiting for recognition'. Although the elf girl has shown a strong ability to receive signals, when the signal is not language but code, she does not have the ability to understand it;

When ordinary trolls and communication soldiers are given the ability to receive sounds in the same frequency band by totems, the former, who have not systematically studied, naturally have no ability to obtain information from them like the latter.

However, in practical applications, their signal recognition capabilities are limited to the '-5 secondary band', that is, the '10-100 kilometers mid-range acoustic range'.

Among them, the brain computing power of the vast majority of witch doctors is limited to the recognition of signals in the range of "long distances within a thousand kilometers";

Although the recognition range of this group of non-advanced witch doctors is still within the normal range of -4 to +4;

Its sound wave has low frequency, long wavelength, strong diffraction, small attenuation and long propagation distance, so it has wider applications in the field of 'sound information'.

"This is how to do."

And they are the main force of technical trolls such as correspondents and signal troops in the current government and military.

Perhaps by then, witch doctors can use group spells to emit high-frequency ultrasonic waves with enough lethality.

As a result, the trolls have achieved a certain sense of ‘private communication’.

And the sound signal reception range of the four of them is also based on the non-advanced witch doctors, and I don’t know how much distance they have covered.

At least, the long span between the east and west of the Black Forest and the complex terrain of the northern mountains cannot really limit their ability to use ultra-low frequency secondary waves to receive signals;

At this stage, it is only because it is impossible to make an accurate estimate that a vague definition of "ultra-long distance beyond a thousand kilometers" is given.

The so-called gap is actually ‘just’ that.

In fact, they have not acquired the ability to 'send' infrasound at this frequency, and when they tried before, all they heard was just 'natural background sound'.

Therefore, this is also the limit of conventional individual communication between the army and the ruling government. If you want to extend the effective transmission distance of sound signals further, you must use relay methods.

At this stage, witch doctors can only generate -6 mid- to low-frequency infrasonic waves and +6 mid- to high-frequency ultrasonic waves through magic and other means.

However, due to the band above +3, it will dissipate rapidly in the air;

Moreover, because their frequency bands exceed the upper and lower limits of the troll's vocal range, the output end also needs the help of magic or totems to take shape.

~~~~~

With the support of the above-mentioned infrasound communication technology, the North-South Exploration Department of the Ministry of External Exploration of the ruling government has successively launched explorations in two directions in recent years.

Because most living organisms are composed of cells, and the cells themselves belong to the category of "liquid with very small bubbles";

Therefore, the signal transmission capabilities they can achieve are not qualitatively different from the highest-level communication level of the Ministry of Communications of the ruling government.

Even if there is, it is only reflected in efficiency;

And when dealing with cave wolves before, witch doctors had already used this method and achieved good results.

Secondly, once they forcibly enter the frequency band other than '+-7', they will experience obvious physical discomfort, and in severe cases, they will temporarily lose their hearing.

As for the lower bands, since the signal has been relatively seriously mixed with the natural background, the degree has exceeded the real-time recognition range of the ordinary troll's brain, so there are relatively higher application restrictions.

The latter is used in the field of 'close range direct audio communication';

For trolls, the '+-4' band is still within the recognition limit of the human ear, but for more creatures, this range is a silent state;

Taking advantage of this difference, the signal sender can raise or lower the tone through magic or totem, and produce +-4 frequency band sounds that they cannot originally obtain through the throat;

And in this process, spells or totems can also constrain the transmission direction of sound waves to a certain extent.

But at the receiving end, because it is in an area that can be directly captured and recognized by the naked ear, it usually does not require corresponding spells or totem blessings to achieve the purpose of transmitting the message.

Being able to hear the '-8 to -10 infrasonic band' and '+8 to +10 ultrasonic band' without being damaged afterwards is a distinctive feature of this stage.

In these two bands, the frequency of sound waves has dropped to an extremely low point, and is mixed with extremely complex natural background sounds;

Without the support of a powerful brain, it is currently impossible to use paper and pencil calculations to find and analyze a specific signal among all these noises.

If we make an estimate of their capabilities based on the size of the Black Forest, then these witch doctors should be able to receive infrasound signals from the No. 3 sub-base on the west bank of the Black River from their headquarters.

The latter, ‘infrasound wave’, is just the opposite.

But this at least shows that high-level creatures are not necessarily taller than their lower-level compatriots.

In addition, this volcano group is almost all active volcanoes, and the thick smoke environment at the mountain pass affects the trolls' ability to observe with the naked eye.

So, somehow the troll got impatient and closed his eyes first, preparing to distinguish by listening.

This sounds amazing, it really gave him some clues...

I came back too late and the plot was seriously stuck.

Let me think carefully about the follow-up, that’s all for today.

Alas, the update is about to be interrupted.
