Episode 92 Heat Shell

I could only think of a magic that used the property, the Heat Dissipation version of 'Thunder Arrow'. Then, it wasn't likely to be more powerful than 'Thunder Arrow'.

It would be possible to increase its power by increasing its size, but since the magic level that it could be learned at was limited to '9', I didn't think it could be given more attack power than the SeventhHighBlade.

Magic level 9 was Alisa's current magic level. It might go up in the future, but since it was a magic that Alisa would use, it would be better to limit it to magic level 9.

"Wait a minute. I don't know if that's true. I should actually try it."

I prototyped an enlarged version and an enlarged thermal version of 'Thunder Arrow'. I couldn't try them here, so I thought I should go to the dungeon and try it.

While making such prototypes, an idea came to me. Among tank shells, there was a thing called a shaped explosive shell. The detonation of explosives produced detonation waves, and the detonation waves caused metals such as copper to collapse and liquefy. When the liquid metal was shot forward with ultra-high pressure, an ultra-high-speed jet 'Metal Jet' was created and penetrated the target.

It seemed that something called the Monroe-Neumann effect was involved, but I wasn't sure. Therefore, I decided to try to reproduce it by creating ultra-high pressure and detonation waves with ultra-high heat.

The D-Particles were shaped like a bowl used for cooking, with a diameter of about 25 cm, similar to the 'Thunder Bowl'. I formed it with the open side up.

Then, I applied 'Roll' in it to generate a vortex of air. That was for sucking in air and compressing it. Once the highly compressed air was created, the shape of the D-Particles was transformed into a cannonball shape so as to envelop it.

I fired it at a monster. The moment the cannonball hit the monster, the additional characteristic activated and heated the compressed air at once. As a result, the air rapidly expanded thermally and erupted from the tip of the cannonball, damaging the monster.

"It was supposed to generate a Metal Jet, but I couldn't prepare the metal with magic."

It seemed that the metal could only be put in when I was preparing it and compressing the air.

The next day, I bought copper wire and pliers along the way and headed to the second floor of the Suigetsu Dungeon. It was to test the magic I made yesterday. The second floor was a forest area, where Orcs and AttackBoars lived.

You could be reading stolen content. Head to the original site for the genuine story.

In a place where there were no monsters or humans, I tried a new magic targeting a tree.

The first was an expanded version of 'Thunder Arrow'. By increasing the size of the D-Particle cone, the speed and the electric current emitted increased, but the consumption of magic power also increased. Was it about a 30% increase in power.

Subtle. The power increased, but the consumption of magic power increased more than that. Poor cost performance, no good. So, next I tried something that used instead of .

When I tried 'Heat Arrow', the tree trunk pierced by the TripleHeatArrow was set on fire. Raw wood was hard to burn because it had moisture, but it seemed that the high heat blew the moisture away and ignited a fire.

Its power was subtle, but it might be an effective attack depending on the type of monster. I tried making a magic called 'Heat Bowl' before, but I rejected it. 'Heat Arrow' this time will also be put on hold.

Now then, I decided to try the 'Heat Shell', which was my favorite.

First, I tried without multiple activations and without metal injection. I created compressed air in a bowl of D-Particles, shaped it into a cannonball, and shot it at a tree.

The reason why the shape of the D-Particles could be changed even after it had been determined was that it was connected by a circuit, which was the mechanism of 'Remote Plate'. Because it was connected by a line, it could transform at the desired timing and shoot at the target. However, it couldn't be transformed into any shape. I could only specify the timing for transforming into a fixed shape.

The cannonball-shaped D-Particle Shell exploded at the tip the moment it hit a tree and emitted high heat. As if the compressed air inside exploded, it expanded rapidly and was forced out of the collapsed tip. In the end, the D-Particle cannonball itself could not withstand the pressure of the expanding air and exploded with a bang.

I knew that if I made it sturdy enough to withstand the pressure, it would become more powerful, but if I made it possible to learn the magic at magic level 9, I had to sacrifice something. In this case, toughness was sacrificed.

I checked where it hit. There was a small hollow. I thought it happened because of the pressure. It seemed to be as powerful as hitting with a hammer.

I cut the copper wire I bought to an appropriate length and rolled it up.

Then I activated TripleHeatShell. When the air was compressed, the copper was put in and released towards the trees. The launched D-Particle Shell flew at high speed.

The moment it hit the tree, an explosion sounded and the tree shook. The blast ruffled my hair. After the blast subsided, when I examined the hit point, it was charred black and had a hole about 5 cm deep. I found a half-melted copper nugget on the ground.

It seemed that the heat generated by the triple activation was not able to melt all of the copper. I felt a response and decided to try it with a five-fold activation. I activated QuintHeatShell and threw in copper. I aimed at the same tree and shot.

The D-Particle Shell disappeared. The next moment, I heard an explosive sound that echoed in my stomach from the trees, the trees shook violently, and the blast wave hit me. After it subsided, I examined it and found a hole about six centimeters in diameter in the trunk of the tree.(TN:These must really be some sturdy trees ...)

The hole penetrated the trunk about thirty centimeters in diameter.

"Oh no, monsters have gathered."

It must have been because I made a loud noise. Three AttackBoars were running towards me.

Of course, the three AttackBoars were instantly killed, but this place didn't seem to be a suitable place to test new magic. I thought that if it was a tree in the dungeon, there would be no complaints even if I destroyed it, so I did it here, but it was no good if the sound attracted monsters. I changed places.

I went to the Adventurer's Guild and asked if there was a place where I could practice magic.

"That's right. If it's a low-power magic, I don't mind if you use the Adventurer's Guild training ground, but if it's a high-power magic, you'll have to go to the paid training ground in the suburbs."

"Paid training ground?"

"I have a map, so I will give it to you."

I got a map and decided to go there. It was about thirty minutes away by bus.

It was a facility that could only be described as gigantic. The facility that was built by hollowing out the mountains had 10 practice fields, and it seemed that the rental fee varied depending on the size.

I rented the smallest practice field. Even though it was called small, it was about the size of a tennis court, and inside was a concrete target.
