Isekai Tensei no Boukensha

I was coming to the North Gate at Grandpa's behest.

As far as I can see, are there more than 5,000 zombies who have been ambushing us, and there are still more. Probably came bypassing the village.

I regretted not using the detection, but I thought it was not fatal yet and started the attack.

"Firestorm!"

Let the firestorm go three times before the zombies notice me and sink those guys near the front row of the zombie herd into the sea of fire.

But the back row of zombies doesn't stop moving forward as if they don't care about the ocean of fire or something. Not to mention the fire went out before the amount of zombies in the back row.

"That's a fucked up method of warfare,"

And someone shrugged. Sure it's a mess, but crushing a handful of defenses in numbers, I thought this was a valid hand against us right now... apart from the zombies thinking that much.

"I'm here for backup on Grandpa's instructions!

"Ooh, that helps."

Short exchanges of words and a series of magic.

"Ground needles, fireballs, air cutters!

Multiple attributes magic reduces the number of enemies. Later, however, the zombies sprang out.

"I don't have a kiri. Even though I'm worried about West Gate... why don't you give it a try?"

and ten firestorms in a row into the center of the grunting herd, burning and killing about 2,000 people who were in the center of the herd, but the zombies were still there.

Even though the 500 m is away, a high temperature heat wave reaches the fort.

"Tenma! Stop burning and wasting your magic!

The wizard I've been catching up with advises me, but never mind.

"Everyone, get back or evacuate downstairs. Hurry!"

and give instructions out loud. At first they were all confused, but the wizard, who had found himself exercising high-powered magic, told everyone immediately and acted immediately. I cast my magic at the side of it.

"'Tornado'"

That was not particularly unusual magic. Strongly put, it was considerably more powerful than the normal one, but it was still about whether you could defeat a hundred or so zombies in one blow... if it was a normal situation.

In the past, during the Great Kanto Earthquake, about 40,000 of the approximately 105,000 deaths were said to have been caused by a phenomenon (...) that resulted in the simultaneous loss of life.

It is also said that the phenomenon occurs at a moment when large quantities of warmed air head up all at once due to massive fires.

Its name is "Fire Whirlwind," the disaster itself grows as it takes in the air around it, and the temperature of a tornado with heat is also assumed to be above 1000°C.

Tenma used magic to recreate the natural disaster.

But this was also a kind of bet, because "Fire Whirlwind" was not fully elucidated in previous life, such as the mechanism of the outbreak.

Tenma, who won the bet, slowly drove the Fire Whirlwind (Fire Tornado) in the direction of the zombies gushing.

The zombies try to escape the whirlwind, but in the end they are sucked into the whirlwind and burned, carved and shattered. The herd of zombies that were headed for the North Gate in a matter of minutes went almost completely extinct. Tenma, who has seen it through, weakens the Fire Tornado with magic.

"Awesome! The zombies are gone!

"Fuck you!

"All we have to do is lose our lives!

and cheers from the North Gate defense team, stabbing the survivors with a stop. Tenma was heartbroken.

(I'm glad it worked ~. It's highly effective, but hard to use, and if I let go of control, I'm going to come this way, and I need magic to turn it off. We have to be careful where we are.)

I drank three potions all at once, thinking.

"Tenma, I'm sorry, but could you hurry up and eat this and head to the West Gate?"

and one of the guards says so, giving him the water and the sandwich he just handed out.

"Okay."

and put the sandwich in the belly to pour in the water and fly to the west gate, the belly making a sound with the water and potion chapong chapong.

The sight I saw at the West Gate was no different from the North Gate.

To be precise, this one has more zombies than the North Gate, but because the wizard was working so hard for it, the zombie invasion was stopped.

I found Uncle Mark in command and spoke up.

"It's a tenma. I'm here for backup."

"Tenma, that would help... by the way, could that have been done by Tenma earlier?

"Yes, my magic."

Answering, Uncle Mark looked surprised, but soon after,

"Then can you ask me to do the same here?

I've heard, so look at the zombies.

"I can do it. However, please help others who can use magic."

Answer, and ask those who can use magic to hit ten fireballs at a time around the center of the zombie herd. I myself release five firestorms.

"Everybody evacuate downstairs!

and gave instructions and chanted 'Tornado' just like the North Gate.

Once again, 'Fire Tornado' hits the herd and swallows most of the zombies, and by the time it disappeared, the herd had been wiped out.

The guards, who saw him, raised their voice of joy and were about to go stab him in the face of death.

Tenma saw it and once she tried to go to the East Gate for a report, the next moment a thin black ray pierced the South Gate, sensing intense and unpleasant signs from the woods on the other side of the South Gate.

The rays reached near the center of the fort and screamed from here and there.

The south gate seemed to be blown away by the gate and some of the walls around it and several of the defense forces were hit directly.

"Dad, Mom!

I raised my voice after a few seconds of solidification and hurried to the South Gate wishing them well.
