From Being Summoned by Eris

"Magic Creation - Additional Magic."

Natsume Yuu didn't say anything, and the [Magic Creation] that had been completely transformed into his own ability was activated.

【[Additional Magic] Originated from Fairy Tail.

A powerful magic that can add attributes and status to any object.

"Additional magic - Magic Sun!"Add the sun attribute of Escanor's magic, the sin of pride, to your own magic.

""The merciless sun!!!"

Natsume Yuu raised his finger, and a golden sphere like the sun appeared on his fingertips, expanding into a half-meter-tall 'little sun' in an instant.

The air around him heated up rapidly in an instant, and the heat wave rolled around.

With a wave of his finger, the fireball emitting strong high temperature flew quickly towards the Demon King's Castle.

The ground below the fireball melted into a charred black pit.

The water vapor in the nearby grass and trees evaporated and turned directly into charcoal.

It was like a falling sun that quickly hit the barrier of the Demon King's Castle.

"" Bang!!!"

A huge roar like an earthquake sounded, and the flames instantly surged and enveloped the entire castle.

���The weaker demons were burned to death. The barrier was strong enough to withstand more than 30 [Explosion Magic] rounds, and it made a sizzling sound under the scorching heat.

"Is this guy with this much magic power really a human?! ? Even the previous generation of heroes didn't have this kind of power!!"

The strongest cadre gritted his teeth, not caring at all that his beard was on fire, and the magic power in his body rushed madly to the barrier, thinking in fear.

This magic is beyond the power of [Explosion Magic], and he has never heard of it.

And it doesn't consume energy when used. Even if he has lived for so long, he has never heard of such a thing!!!

"The Demon King was not burned to death, was he? I haven't even seen what the Demon King looks like yet."

Aqua put her hand on her forehead and said in a light tone while looking at the burning Demon King's Castle.

The heat was so intense that even though she was hundreds of meters away, she could still feel the burning sensation on her face.

"Well~ He is a demon king after all, so he won’t be burned to death so easily.

After all, he is a demon king, so Huihui didn’t think he could be killed so easily.

"If I summon water to put out the fire, will it turn into a steamer inside?"

Aqua smiled slyly as her eyes turned.

"It feels good."

Huihui's eyes lit up, and she said with a curious tone.

"These two people look nice, but what they say is too scary."

Darkness thought to himself as he looked at the two people with a twitching mouth.

"Forget it, after all, we have to go in and look for the Demon King later, and we will be the ones who get hot by then.

Seeing that Aqua didn't look like she was joking at all, Chris hurriedly stepped forward with a smile to stop her.

"...I don’t want to get sticky either.

Although she is the goddess of water, Aqua doesn’t want to experience the hot and humid feeling of a ‘steam sauna’ unless she is taking a bath.

Thinking about what will happen after she goes in, Huihui nodded silently and didn’t mention it again.

As they talked passionately, the flames over there began to fade.

"I survived....It can actually cast such a terrifying magic, like the sun falling."

The strongest cadre, whose face was blackened by the burning beard, gasped and looked at Natsume Yuu in the distance in shock.

Although it was a bit reluctant and the barrier was already full of holes, it still held on with the magic power drawn from the demon world.

However, the terrifying high temperature also caused heavy casualties in the Demon King's Castle.

"？？？"

Suddenly, he found that the hero stretched out his hand to him.

Before he could react, he suddenly found that the hero who was hundreds of meters away appeared in front of him, and one hand was pinching his neck.

"......"

Feeling the warmth coming from his neck, the strongest cadre fell silent and stared at the man in front of him without saying a word.

"Can I admit defeat?"

He said with difficulty, his wrinkled face looked like a black chrysanthemum.

Natsume Yuuya smiled, and when his five fingers loosened, he turned his waist and swung his long right leg.

Under the powerful force, the strongest cadre turned into a kite and flew hundreds of meters, crashing into the barrier of the Demon King's Castle.

Without the support of the magician, the barrier, which was already shaky due to the [Merciless Sun], was directly shattered like glass. The front cadre did not stop, and broke through the wall of the top floor and sank into it.

"Oh~ Good shot!"

Aqua gave Natsume Yu a thumbs up

"The demon king should be on that floor."

Youyou said as he looked at the thick smoke rising after the explosion.

"There is indeed a very strong magic there. We can go home after getting rid of him."

Natsume nodded slightly, squinting his eyes and looking over there, speaking as if he was strolling in the garden.

In the flash of light, the figures of several people disappeared and came to the Demon King's Castle.

A sturdy old man with two horns on his head, wearing a black robe, sat majestically on the chair in the middle.

Of course, if he hadn't been sweating profusely and wiping his sweat constantly because of the heat, he would look much better.

Beside him stood several guards who looked quite powerful, but they were also sweating a lot.

And on the wall of the room, the strongest cadre was directly embedded above

"Is this the Demon King? He looks similar to a human being."

Youyou looked at the old man curiously, who looked like an ordinary person.

"Yes, although it looks like that, the oppressive feeling is indeed the Demon King."

Chris nodded and looked at the Demon King with an inexplicable look.

It is because of this person that the reincarnation rate in the world he lives in is so low.

"I didn't expect that a strong hero like you would appear in this generation."

When Natsume Yu and others were looking at the Demon King, the Demon King opposite them was also looking at them, and then said in a deep tone

"Natsume Yuu...This name, you and my ancestors probably come from the same place."

"Come to think of it, my ancestors were also heroes."

When the demon king said this, a complicated expression appeared on his face.

""Eh!!?"

Huihui and the others were extremely shocked by these words and looked at the Demon King in disbelief.

"Are you interested in knowing why it has developed to this point?"

Seeing the expressions of the few people, the devil said softly

"Not interested!"

Meihui and the others said this in unison.

This was a totally unexpected answer, and the Demon King stood there in shock, looking at them.

Why are you acting so surprised if I'm not interested!!!
