Reincarnation with AI (Unemployment-Free)

A few days later again.

Rudius had a question on his mind.

The first time I cast the spell, I used my right hand.

But why?

Why not the left hand?

Was it because I subconsciously thought of using my right hand that it became my right hand?

Is it because I subconsciously wanted to use that hand to cast the spell that it will be that hand?

This is an automated process that requires no conscious thought, but there is always a subconscious element involved.

After mastering the incantation-free technique, one can cast spells with both hands, and also cast mixed spells.

Just like waving your arm to make a movement, if you can do it with your left hand, you can do it with your right hand naturally as well.

For example, fire plus wind creates hot air, and fire plus water creates hot water.

But the question is, if hands can do it, what about feet?

Having deeply experienced the process of growing up, Rudeus instinctively began to deduce the process of releasing magic from scratch.

Rudius had a gut feeling that this was feasible.

If Goku can unleash a Kamehameha with his feet, why can't I release magic with my feet?

Although Rudius didn't have much knowledge of anatomy and had only watched some videos out of interest, the logic of limb growth must be consistent, which is not hard to figure out.

The main neural pathway in humans runs from the brain to the spinal cord. The nerves in the limbs branch off at different locations on the spinal cord, and the muscles are different, but the distribution logic should be consistent.

Based on the fact that probably no one in this world would have the idea of ​​casting magic with their feet, and even if they did, they probably wouldn't have the means to put it into practice.

Having no prior scientific experience, Rudius decided to start his own experiments.

Question: "Are the nerves and blood vessels in the human hands and feet distributed according to the same logic?"

The distribution logic of nerves and blood vessels in the hands and feet is similar, but functional differences lead to variations in the details...

That's right, the nerves in the hands and feet all branch off from the spinal nerves, and the blood vessel distribution follows the same logic, so there's definitely no problem.

People in the Middle Ages certainly wouldn't have understood this kind of anatomical knowledge; they would most likely have thought it impossible for hands and feet to be the same.

But for Rudius, who had watched videos more than once studying why humans walk upright, this was not hard to come up with at all.

Even from the perspective of historical inertia, modern people can imagine that the human limbs must retain a similar "wiring" logic.

Medieval humans were obviously unaware that their ancestors evolved from quadrupedal locomotion to bipedal locomotion, so they could not make any inferences.

Once inspiration strikes, Rudius finds various "evidence" in his mind to constantly corroborate his inspiration.

Rudius recalled how amazed his neighbor was when he saw someone writing calligraphy with their feet on television in his previous life.

But Rudius thought it was making a fuss over nothing, feeling that his neighbors weren't that different from medieval people.

This isn't something you can understand just by thinking about it.

Or perhaps you don't even need to think about it; you can understand it just by looking at it. Maybe this is the "highway" in Rudius's mind.

However, to avoid making assumptions, it is still necessary to ask the AI ​​for a definite answer.

In terms of results, things went relatively smoothly.

Rudeus began to try using his feet to cast spells without chanting.

Just like the awkward feeling you get when using a voiceless technique for the first time, although it feels awkward, you can use it smoothly.

They can even use hybrid magic that goes with the flow.

This brings us back to the analogy of hands. Although the left hand can naturally mimic the movements of the right hand, the level of proficiency between the dominant and non-dominant hand is obviously different.

This refers to the distinction between left-handed and right-handed people.

These can all be gradually strengthened and formed into habits through later training, which are the corresponding automatic bodily reflexes.

Now that it's logical to use your feet to cast a spell without chanting...

Speaking of this, we have to mention Rudeus's signature spell from the original work.

Mud marshes, a magical mixture of earth and water.

In the original work, when casting the spell, there was a gesture resembling that of a certain blond alchemist, slapping the ground with both hands to initiate the alchemy.

Now that Rudeus has learned to cast spells without chanting using his feet, he can skip this step and cast them directly with his feet.

From a tactical perspective, this eliminates the need for a crouching maneuver, which should be more practical in close-quarters combat.

And because it is performed without chanting, it is even more difficult to guard against.

Rudeus envisioned the possibility of wearing loose clothing and concealing his hands within it to unleash magic.

In a world where magic requires chanting to unleash its power, this can provide a significant advantage in battle.

It's like in a past life you hid a pistol in your clothes so you could assassinate your target through your cloak, or a short knife could be pulled out directly from your clothes.

For a more dramatic interpretation, it could be something like Itachi Uchiha in Naruto, who hides his hands inside the large Akatsuki robe to perform hand seals, or Gin Ichimaru in Bleach, who hides his short Zanpakuto inside his clothing and shoots his opponent directly.

This is undoubtedly an extremely insidious and useful combat tactic.

It involves the most important information aspects of combat.

Extending this line of thought, earth magic requires the user to touch the ground to activate it.

Warriors would definitely anticipate the mage's movements to execute extremely dangerous moves like ground spikes.

Although it has not yet been tested in real combat.

But Rudius simulates in his mind, assuming he is a warrior.

If you see a mage crouching down and touching the ground, it means they are casting earth magic, so you will stop moving immediately to avoid running into the spikes and getting yourself killed.

For the soldiers, this is a bit like playing 123, freeze.

Upon seeing the mage unleash earth magic, immediately prepare for defense. Once the magic ends and the mage begins chanting again, charge in and kill him once more.

The reason why soldiers wouldn't be wary of mud is precisely because of this.

This is not only because no one knows how to use this kind of mixed magic, but more importantly, it is to guard against the more dangerous spike attacks.

Compared to the deadly spikes that would kill if one were to collide with them, the swamp that restricts movement is obviously less important.

The opponent, on the contrary, will be trapped in the mud because they are on guard against the spikes.

As a result, after the opponent stopped in their tracks due to their preconceived notions about combat experience, they were caught off guard by the unfamiliar swamp.

This is probably why the original protagonist's swamp technique was so effective.

Because according to this logic, this magic has a percentage hit rate.

In other words, someone unaware of this move would almost certainly fall victim to it based on their regular experience fighting mages.

That's probably why the male protagonist in the original work earned the title of "Morcery".

Thinking about this, Rudius felt something was amiss.

This title, to some extent, reveals the original male lead's strength.

In other novels, information about a magician's signature spells is very important and needs to be hidden.

However, considering that the original male protagonist needed to become famous at the time, and that there wasn't that much demand for PvP in this world, it wasn't really a big problem.

Furthermore, the fact that the original male protagonist received such a simple title itself illustrates how uncommon this magic is.

If we take the simplest fireball spell as an example, then people probably wouldn't use "fireball" as a title.

Because this magic is so common, it's a basic magic that everyone knows.

If someone earns a title for using the fireball spell exceptionally well, it will likely be something like "Explosive Flame" or "Machine Gun," which better reflects their firepower or rate of fire.

It directly describes the mage's focus, rather than concentrating on the fireball spell itself.

The name "mud swamp" is so plain that it doesn't emphasize anything; it simply describes a phenomenon.

This means there's no point of comparison, which indicates that very few, if any, people use this magic.

This fully demonstrates that mixed magic has a very high barrier to entry, which is beyond the reach of most magicians.

Because it's impossible to achieve a spell without chanting, ordinary magicians must chant two spells in sequence to achieve the effect of mixed magic.

In practical terms, even if the result is the same, that kind of mixed magic is a mixture of the physical phenomena that occur after the magic is activated.

To create a swamp, an ordinary magician should first use a water cube to wet the land, and then use earth magic to form a swamp.

Instead of directly casting a spell called "swamp" like Rudeus.

This is a fundamental difference.

When you have a teacher in the future, you can ask this question.

Having realized this, I understand what a true genius is.

Rudeus focused on training his ability to combine magic and practice magic in parallel.

How to combine and activate the four elements of magic: wind, fire, water, and earth, and how to activate them simultaneously with both hands and feet.

Can all four limbs simultaneously cast mixed magic?

What is the upper limit of this?

It has nothing to do with the brain's "bandwidth"?

If not, can it be achieved through repeated practice?

After automation, is it possible to free up some "bandwidth"?

Rudius thought that "bandwidth" was called "focus" in some Western fantasy novels, and that magicians also had ways to make spells not consume "focus".

Speaking of which, I'd love to be a mage in one of those worlds...

As for now...

Only useful spells can be selected, and through constant deliberate practice, a "highway" is formed in the brain, making the casting of spells completely automatic.

In short, it's all about constant practice!

Ever since Rudeus mastered the magic of combining fire and water, he no longer wipes his bottom after defecating.

Because the toilet paper in this world is too terrible for Rudeus's delicate bottom!

So Rudius chose to wash it directly with hot water!

Since mastering the magic of combining fire and wind, I no longer feel a wet feeling in my butt crack after pooping and washing my bottom.

Because Rudius can be dried directly with warm air!

Since mastering the magic of combining fire and earth...

Okay, the fusion magic of fire and earth isn't that useful. It's about heating earth with fire to form something similar to the Lava Release technique, but to be honest, it's hard to use.

However, Rudeus created a non-fusion version of the fusion magic, concealing the fireball spell within a stone projectile.

It perfectly makes up for Rudeus's regret that he couldn't set off firecrackers in another world, and it makes up for his childhood without firecrackers in a foreign land.

just kidding.

Since they've created something resembling gunpowder, it's not just for setting off fireworks. Although fireworks are beautiful, they should be quite useful for flirting with girls.

But landmines are definitely more attractive to men.

If the left foot casts a swamp spell, the right foot will simultaneously cast a mixed fire and earth bomb spell hidden in the swamp.

What does such an insidious tactic mean for a completely unsuspecting indigenous person?

But this is not easy to do.

The fragments from the explosion of the stone bombs are unlikely to cause effective damage after penetrating the mud. Even if Rudius tried to create a one-way explosion similar to the Claymore mine, the destructive power would still be insufficient.

More effort is needed to put it into practice.

At this stage, it would be more practical to trap the opponent in the mud and then immediately use the original male protagonist's other signature spell, Rock Cannonball.

This combo is indeed simple and unadorned, yet it possesses a beautiful, unpretentious quality, like a shot delivered with a melee attack.

Focusing on practicing existing powerful attack spells is also an excellent choice, although it may lead to the opponent being on guard in battle and losing the advantage of information.

However, even without chanting, it can still achieve some unexpected effects.

The most fatal flaw is that this unexpected effect is not enough to completely ruin the opponent.

Rudyus aims to use the information gap to directly defeat his opponent at the very beginning of the battle.

Therefore, based on the differences in intelligence, hybrid magic is clearly a better choice.

Fortunately, practicing with rock cannonballs doesn't require much brainpower; the process of consuming magic power each day can be completed spontaneously.

Rather, it's more accurate to say that the original male protagonist, being a human who transmigrated from another world, failed to develop a complete set of hybrid magic that could work together with it.

Although they achieved overwhelming superiority over the indigenous people by using no chanting, they did not utilize scientific knowledge to achieve a "dimensional reduction attack" against them.

To be honest, without AI to speed up the thought process, Rudius wouldn't dare to guarantee that he could eventually achieve a level of overwhelming power against the natives; at least not at his current age.

But the original male protagonist's spirit of exploration seems to have completely disappeared after he discovered the absence of chanting.

You can't say the original male protagonist had no interest in magic; the anime clearly shows his excitement about being transported to a world of swords and magic.

The original male protagonist was also highly skilled in using various kinds of magic that could be mastered in other worlds.

As for expansion...

That person didn't finish school for some reason, but they explored on their own based on their interests and used their past life's experience to create figurines...

It has achieved considerable success on an artistic level...

Then, through collecting figurines, I made friends, and with their help, I completed the development of the magical armor...

Okay, I can't make this up anymore...

For someone like Rudius, who has a scientific mindset, he genuinely believes that anyone who can't learn math and physics is an idiot.

The original male protagonist was probably not a key researcher in the development of the magical armor.

From the perspective that knowledge is power, the original male protagonist, this shut-in who doesn't go to school, is really weak...
