Wizard: I brought the wrong system.

Chapter 115 Fiery Sword Technique
Just as the Instantaneous Movement Technique doesn't require bare feet to cast, when it comes to the problem of high temperatures, Yaro's first thought is to wear a pair of gloves.

But the real difficulty lies not in this, but in the longsword that comes with this martial art.

Simply wearing gloves is not enough to solve the problem of heat buildup.

If this heat is not dissipated, even if you wear gloves, the accumulated high temperature over a long period of time will still cook your hands.

Therefore, two more devices are needed here.

One is a sword hilt cooling device, and the other is a heat absorption device.

What is the best, cheapest, and most readily available cooling material?
Without a doubt, it's water!

Water is readily available, and as it vaporizes, it carries away a large amount of heat, keeping the temperature around 100 degrees Celsius. Combined with the heat insulation of the gloves, this ensures that the palm temperature remains normal.

Simply ensuring the normal temperature of the palm is not enough, because this temperature is caused by the heat fusion technique.

Yaro didn't cast the Helium spell to vaporize water into steam; he needed to find a way to utilize the heat.

Yaro vaguely remembered that the thermal conductivity of water was around 0.x.

Among conventional materials, diamond has the highest thermal conductivity, ranging from over one thousand to over two thousand.

Among conventional metallic materials, silver has the best electrical and thermal conductivity, which is around 500 degrees Celsius.

Based on this knowledge, Yaro planned to equip the hilt of the longsword with a mesh-like evaporative cooling system.

The middle part of the mesh is covered with silver or diamonds.

These silver or diamonds will serve as heat transfer materials, running along the core of the sword all the way to the blade.

Because the thermal conductivity of the material in the center is much higher than that of water, most of the heat will be absorbed by it, and the remaining little heat will be controlled by the water evaporation system, so it will no longer cause any harm to your palm.

As for the blade, Yaro plans to cover it with extraordinary materials such as hot molten stone. Based on the principle that high temperatures will activate fire elements, the heat transmitted from the sword core will be absorbed by these hot molten stones, which will also violently activate the fire elements contained in the hot molten stones.

In this way, when the blade strikes the enemy, the fire element on the blade will come into contact with the low-temperature object, causing a violent explosion.

The specific principle can be understood by referring to the phenomenon of water droplets falling into hot oil.

These explosions will deal both elemental and physical damage, greatly compensating for Yaro's lack of offensive capabilities.

……

The previous theories were all correct; the key issue lies in how to handle the steam after the water in the handle cools down.

Steam should definitely not be released from the blade, as that would cause the active fire elements accumulated on the blade to be directly ignited by the steam, which would not only consume the stored energy but also cause random explosions, thus affecting the stability of the sword.

Taking all factors into consideration, the steam outlets could only be designed at both ends of the sword hilt, and could only be emitted diagonally backward.

In that case... could we use this steam to increase the power of our slashing?
The added power from steam may not be much, but even a little bit is good!

……

He was extremely excited while writing, but after he finished, Yaro looked through the notebook and hesitated.

"This thing... is it really a move that a normal person could learn?"

There are too many things to pay attention to in this move.

The water temperature and volume at the hilt, the amount of steam, the direction of steam release, and the heat content of the blade...

Furthermore, because steam is ejected diagonally backward from both ends of the hilt, the moves must be redesigned, which means that variations such as 'upward slash, thrust, and slash' are also included.

……

[Ding! Martial art "Blazing Sword Technique" discovered. Do you wish to learn it?]

This system is awesome!

But I've always relied on myself!

Learn!

"Hiss~" The indoctrination of knowledge is not comfortable, but the feeling of becoming obviously stronger and quickly learning new moves is too exhilarating.

Yaro could clearly sense that countless new pieces of knowledge were being injected into his consciousness, and that his muscles were undergoing subtle changes, with many different memories being added.

At the same time, some of the knowledge one already possesses is being integrated and consolidated.

These feelings came and went quickly; in just a moment, all the pain had dissipated, leaving only a thoroughly enjoyable sensation.

"Cool!"

Once his emotions had calmed down, Yaro thought about his previous feelings and thoughtfully opened the system.

……

Perhaps due to his increased height, Yaro's stamina has recently increased slightly.

Gently tapping the table, Yaro thought to himself, "Several basic sword techniques are indeed gone, and the newly learned skills have directly reached the intermediate level."

Recalling the newly learned martial arts techniques, one can clearly sense that the previous moves have not been forgotten, and the new variations are also well understood. However, there are still some flaws in the coordination with the power of the longsword.

There's no need to rush this, since the Fiery Sword only exists in theory; no physical prototype has been made, and it can't be practiced.

Yaro shook hands slightly, but it was as if he had suddenly grasped a red-hot piece of charcoal; the burning pain made him reflexively pull his hand away.

Looking at his slightly reddened palms, Yaro couldn't help but smile.

"The heat fusion technique is complete."

……

After changing his clothes, Yaro prepared to go out.

Today he's going to explain the situation to Wizard Bosco, to relieve him of the task of collecting fluorescent powder so he can focus on alchemy later, and also to demonstrate how he learned and mastered the 'Heat Melting Technique' in just one day.

Many people spend a long time just learning a zero-level magic trick.

For example, Keita, who sensed mental power along with Yaro, still cannot cast a level zero spell out of thin air, let alone a level one spell, which is more than three times more complex than a level zero spell.

The reason why Yaro was able to cast the level zero trick - Magic Hand - yesterday was because he was familiar with three level zero tricks, and the structure of Magic Hand was relatively simple. Even so, he still needed the assistance of hand seals when casting it, and he only managed to succeed after several failures.

From these perspectives, this 'Heat Melting Technique,' which can be cast empty-handed and without hand seals, is definitely something worth having.

"Look! Here's a super genius in alchemy, just waiting for you to train him. Why waste time catching wanted criminals!"

Hmm... that's what Yaro was trying to say.

Although he didn't know whether his sharp edge would ultimately be a good thing or a bad thing, he didn't have time to worry about that now.

With a trembling heart, Yaro stepped into the mysterious hall once again. When he passed by the law enforcement headquarters, he was surprised to find that all the law enforcement officers coming and going had serious expressions and the atmosphere seemed somewhat tense.
