Isekai Cheat Magician

Rin Sensei's Course on Effective Use of Modern Knowledge

"You think you're gonna do a lot of damage to the herd in one shot?

Gerard doubted his own ears at Rin's words.

The offer itself is most welcome. If extensive extermination magic can be used, there is no reason to refuse it.

But how?

Even Lemia, for example, would not be able to defeat three digits in one shot, no matter how wide a range of magic was used.

Rin said, "If you don't take it off, it'll cost you 100." I don't see how we can make that happen. No matter how many force magicians.

"Is that possible, Lynn?

Lemia was also asking Rin if she couldn't believe it.

Rin affirms without interrupting her hair.

Rin, who is Teng himself, and his friend Taiichi, who said he hasn't changed his complexion on this occasion. Neither Mullah, nor Lemia, nor Gerard knew how to take it, and they were extra.

"You should let Rin do it."

"Don't make it easy, kid."

"If Rin says he can do it, he can."

What basis is there for that? I ran out of confidence.

"... can I leave it to you? We need to get our hands on the operation now. I knew you couldn't do it.

"It's no problem. If I don't even get the timing right."

I don't seem to doubt the success of the magic itself. My eyes said, "Let me try it," if I looked at Fumi Mula and Remia.

Even as Gerard, I am very fascinated by Rin's suggestion that he can defeat a three-digit demon with a blow from the encounter.

"... let's be good. Then at least tell me what you're willing to do."

"Okay."

Rin nods.

"The attributes used are fire and water. The name of the phenomenon that causes it is a water vapor explosion"

Suji-kun. No image comes to a boil from the words. Apparently they cause an explosion, but fire and water are conflicting attributes. Normally, it activates with care not to wear it.

"How many shots can you shoot?" "Speculation, but maybe three." "Well, just one shot in the head. It's not good to use." "Right."

Watching the two of them interact, it became a story after they shot the magic. It's strange because it seems more terrible not to believe when you get an attitude that presupposes success so far.

"I've probably never used such magic before. It bothers me there." "Don't worry. I'll leave as soon as I hold Rin. I won't let Rin touch a finger." "... silly."

Pink air begins to flow between Taiichi and Rin. By watching the exchange, the three of them became feathers of heartburn.

◇ ◇ ◇ ◇ ◇

Operation that is supposed to bump into the demons directly from the front without a small workmanship. The adventurers, who had been ordered to wait temporarily before the black masses that appeared on the horizon, were bewildered.

According to a report by the scouts, each demon is divided into three herds by its speed of movement. The number in the first line is roughly 140. Almost the same total number of adventurers who took part in the Azpia Defense Battle.

Simple calculations, one at a time. Not bad as a first fight. Shoulder watermarks are a good place just because many adventurers were looking to gain momentum and morale here.

Gerard said he would shoot a single wedge in.

What does it mean to fulfill?

The answer began with one word boiling down to a different tone.

"There's tons of water on the ground."

Some are noisy, and others are just dead.

The ground creeps up and there's a lot of water accumulating there. Just in the direction of the demonic flock. It will be difficult to change direction from now on. Especially in group behavior.

The moment the demons reach that point.

Several large fireballs fly to the water reservoir. That's the signal to detonate. The ground played abruptly, like a beast waiting for its prey.

From there it was a flash of events.

An explosion of suspicious magnitude scattered a roar and swallowed a whole herd of demons.

◇ ◇ ◇ ◇ ◇

A vibration that echoes at the bottom of the belly rocks Azpia. A fierce storm struck the three at the same time. I can tell from the rooftops of the guild. How much scope did the current explosion blow?

The three of them looked blurry at the black smoke rising above them.

Water vapor explosion. When water vaporizes, the volume jumps thousands of times. Rin said it was something that caused the gas to expand rapidly and wake up.

"There's a volcano, isn't there? When groundwater and lava collide, depending on the conditions, there will be a water vapor explosion. I'm going to use that principle this time."

That's what Rin said before. Nihon knows what volcanoes are like. In this world, it is called 'the wrath of God on earth' and so on, even though he says it is a paranormal phenomenon that barely even understands the principles.

"Lemia. What's that magic worth?

Remia slowly turned her gaze to Gerard.

"... are you seriously asking?

"No way. Play."

Yeah, and Remia snorted.

"One blow changes the battlefield. Tactical. If they activate magic of that magnitude on their own, they can't do it ridiculously."

Guess so, Gerard says.

"So what do you think of the value of Lynn herself?

……

Remia doesn't answer. Next to it, Mullah salivated.

"Look, I blew 100 meters in diameter."

"... I don't know. But I don't want to threaten you."

"Hmm?"

In response, Gerard peeks intriguingly into his face.

"I don't think that's all Lynn can do. If you feel like it, it's possible to make it even more difficult."

The magic of fire attributes and the magic of water attributes were mixed and used as normal. They spoke directly of antithesis to the common sense of witchcraft in this world.

"If your mental state is normal, you won't do it personally. They are not those who boast of their power and rejoice, nor are they to be hurt by the dark clouds. That's why I can't imagine what would happen if we hunted him down without darkness."

"I see."

Arm in a convincing manner, Gerard nodding a few degrees. Lemia glanced at him and continued "to it".

"If you get your hands on Lynn poorly, Tych will definitely come out. From me, you're more of a threat."

Gerard, as well as Remia, who imposed his training, has never even seen the bottom of a fat man, Mullah, who worked with him as an adventurer. That strength despite saving power. I can't even imagine what would happen if Taiichi gave it all.

"I am."

Remia laughed invincibly.

"I'd really like to advise a fool who's got his hands on Azpaia."

Don't put your hands on what Tych wants to protect.

It's not a joke or anything. Remia's words. Mullah and Gerard nodded heartily knowing what the intention was.

◇ ◇ ◇ ◇ ◇

Rin creates fireballs and makes them stand by. One by one is a high temperature of 1500 degrees Celsius.

I say slap this into the pond that I created earlier.

"In fact, I don't know if it really works..."

Rin laughs bitterly. A rare cut-off departure for Rin. I think it will be possible to step on it.

I guess I'm anxious because I didn't experiment, Taiichi expects. There's no place to experiment, such as a water vapor explosion, so I can't help it.

"You're gonna be okay, maybe"

"It's really easy."

"Mm-hmm, you can't help it because you have to try."

"... Something pisses me off just to be honest"

During such an exchange, a period of demons had come a long way.

"Here we go, huh?

"Anytime."

Confirming that Taiichi had said so, Rin unleashed a fireball. Drop off the fireballs that tear the air and fly away.

"... eh, that"

Kakun and Rin collapse.

"Are you all right?

"Ah, haha. I didn't get 30%... I think I used half my magic..."

I've never seen Rin use half his magic. I mean, that's about the size.

"Ta..."

I was about to ask if I could stand, and there was an explosion around 100 meters away from Taiichi and Rin.

Water vapor explosion is a success. but apparently not if you're saying that.

I don't have to worry about getting caught in the explosion itself. I'm far enough away. However, the aftermath of the explosion was not limited to that. When Taiichi turns his attention, a dramatic breeze of speed is spreading in eight directions around the explosion point.

There is no way to avoid such a physical phenomenon. Instead of avoiding it, take it down.

Rin hasn't stood yet.

"Rin! Excuse me!

"What... Yikes!?

Rin's back and knee with an apology. Hands in, hugs him and jumps. It's the same 60% enhancement you had when you defeated Red Fenwolf.

Moving quickly away from the aftermath of the explosion, Taiichi stops moving.

Are you sure you want to get away from me?

Taiichi looked up at the black smoke. A view that tells the story of the awesomeness of the explosion. I felt as if it was war, etc., and realized that weapons and civilization were in a situation that was not so different from war.

If we can only help ourselves, I'm not afraid that there will be 1000 demons or 2000 demons. But Azpaia has Marie. There's Almeda. A cafe brother to a weapon shop jerk who made me better.

There are plenty of people who want to protect you.

That's why we do the number reduction.

"Rin. Are you okay now?

I still had it. Now that we are fortifying ourselves with magic, not just Rin, but about one person doesn't feel the weight of a spoon.

When I saw Rin, he was turning that way. It's bright red to the ear. I thought about how I could light up... and realized how I was holding Rin.

This is it.

Of iron plates in galgays, etc.

"It's a princess hug, I know"

"I don't know... I'm embarrassed..."

Rin's voice is weak. Let me down, what's not to say? Taiichi doesn't know her heart as well as she can see around it. Unfortunately.

"Well, it's okay because I haven't seen anyone."

"If you're watching me, I'm really dying..."

After standing still for a while, Rin finally got off Taiichi.

With his face still slightly red Rin, Taiichi turned to the herd of demons.

Reduce the total number so as not to be noticeable.

Probably going to be a protracted battle, is Gerard's valve. The more time passes, the more it becomes painful. We shall follow Remia's advice that we should reduce the number of demons we deal with around the area that was plugged in later in the fight.

Preemptive punch is a huge success. This is the real war to come.
