The witch doctors in the program team are constantly improving the details of the experiment, striving to find out most of the problems that may be encountered before officially starting the research, and then find solutions in advance.

Although there are many problems, if you don't get started, you may not be able to encounter them in advance;

But it's hard to say that they're doing useless work, because there are many more things that are obviously going to be obstacles, and the witch doctors are finding out and overcoming them.

At the same time, the witch doctors in the instrument group were not idle, various instruments were designed and finalized, mass manufactured, and various cell dyes were also modified.

After the soldiers who went to hunt monsters also returned with their loot, the research work of detection spells was also carried out in a timely manner.

Originally, Blade Fang was still a little worried, because he wasn't sure if the tribe could really get the ability they wanted from the kind of demonic beast that Morligan Witch Doctor had said.

What if it was a 'normal ability' like that of bats in previous lives?

Fortunately, after taking out the magic core and analyzing it, the witch doctors successfully decomposed the corresponding 'sonic wave' type spells.

Bladefang breathed a sigh of relief and sighed at the strange nature of the evolution of the creatures in this world.

Here, the evolution of living things seems to have its own set of trends, and most of the enhanced abilities will eventually appear as 'spell-like'.

The witch doctors have two diametrically opposed views on this.

Some of them are believed to have intracranial magic crystals, and then let the creatures gain relevant abilities on this basis;

The other part believes that it was the creatures that slowly evolved the precursor of spell-like abilities based on their needs, and then gradually evolved and enhanced them into spell-like spells that existed in the magic crystals.

The blade itself is more supportive of the second point of view.

He speculated that sorcery-like spell-like was an adaptive change in which creatures sought to enhance their abilities and wanted to actively control them.

For example, 'brute force' spells may have been just a hormonal response from an organism in response to danger, just as 'adrenaline' was for humans in previous lives.

Later, due to the peculiarities of this world and the instinctive pursuit of that state by living beings, specific areas of the brain gradually change.

In the early days, this change may be to make the brute force instinct more easily stimulated, then to be actively excited, and later it may also go through the process of 'effect enhancement'...... and slowly evolved into a spell-like ability.

Of course, this is just a speculation, and it is not enough to form a definitive conclusion without rigorous research.

But no matter what the outcome is, the magic crystal spells of the Monster are like a gift from heaven to the witch doctor.

Because this greatly lowers the initial threshold for witch doctors to study spells.

Among the various magic crystals, there are always various types of spell abilities;

These spell abilities can be further refined and converted into strange rune groups;

Within various rune groups, various runes can also be decomposed into different functions.....

As a result, although the witch doctors are still in a state of knowing what the magic is and not knowing why, these various runes are enough to support their continuous development.

Someday, they will develop in this 'support' to the point where they can go back and truly understand the underlying logic of the spell.

Maybe that's when the witch doctors really grasp the rules."

Getting back to the point, the witch doctors first began to analyze the blind bat's magic crystal.

The Blind Bat is a specialized low-level magical beast that has only resolved a complex set of runes from its magic crystals, which is exactly the 'sonic wave' related spell that the witch doctors are looking for.

Then, in repeated attempts, they gradually figured out what kind of tasks each component of the rune group took on in the complete system.

As a result, the complete rune group is divided into three sub-rune groups, which play the roles of vocalization, directional propagation, and receiving feedback.

In 'Vocalization', the witch doctors find the lower rune group that determines the frequency of the sound waves;

The lower limit of the wave frequency is within the normal hearing range of the troll, and the upper limit is beyond the range of the troll's hearing.

In response to this, Bladefang named the part that went beyond it after the troll word "ultrasound", and listed "determining the value and unit of sound wave frequency" as the tribe's future research plan.

The research on the remaining two sub-rune groups also has its own results.

For example, the subordinate rune groups determined in 'Directional Propagation' can be used to change the direction and path of 'sound waves';

Another example is the subordinate rune group obtained in 'Vocalization', which can play a role in adjusting the vibration frequency of the vocal area.

When these results were combined with the various runes already in the tribe, a new spell was created that could be used by the troll witch doctor, named 'Ultrasonic Detection'.

The release principle of the 'Ultrasonic Detection Technique' is to change the frequency of the troll's throat through the technique, so as to emit sound waves at a frequency within the target range;

It also enhances the ability of hearing to receive sound in a specific wavelength range, and enhances the ability of specific areas of the brain to process this type of sound wave information.....

Under the effect of these factors, it will eventually play a corresponding detection role.

However, this kind of sound wave is very easy to be lost in the air, so it must be used as close as possible to the 'detection target', so it does not have the effect of 'long-distance detection'.

But when it comes to medical research, it's just right.

However, in this way, the 'inspection' posture becomes more strange to the blade teeth, and the practitioner has to stick the face to the inspected area as much as possible to reduce the error rate.

But the witch doctors were quite satisfied with this, and they didn't think that the 'personal examination' was a big deal.

Not only did Blade Tooth not scoff at their concept, but compared the two, he found the inappropriateness of what he was thinking.

'Damn.... It's all like this, what kind of hypocrisy am I! Is there a little bit of self-consciousness of scientific researchers! “

Considering himself a 'researcher', he deeply reflected on his previous hypocritical thoughts, and put aside the idea of "swearing not to use this technique", and looked forward to the role it could play in the research along with the other witch doctors.

With the successive arrival of detection methods such as acoustic techniques and microscopes, the successive achievement of experimental subjects and experimental sites, and the mass manufacturing of small tools and small instruments such as ice crystal slides, resin gloves, and tweezers, the preparations have become closer and closer to perfection.

Next, after the experimental design is ready, the research can be officially started.
