Summoners War: Only I Summoned Divine Beasts

*Bam!*

An earth-shattering sound traveled through the sky, forcing all of them to cover their ears instinctively.

"Kh." Nathan gritted his teeth and turned around, looking at the sky. "What's going on?"

"An enemy attack?" Selena looked worried.

"The sound is so loud…"

"I don't know what's happening…"

Nathan's expression turned solemn. He could hear the people panicking outside, wondering the same thing.

He bit his lips and said, "I'll take a look outside."

"We'll follow you."

Nathan looked worried, but he wasn't aware of what happened. If it was an attack, it would be better if they were to stick together because he could protect them. Explore more stories at empire

Nathan nodded. "Sure. Let's go."

Nathan summoned Nidhogg while shouting, "Nidhogg. Go up. We'll check the surrounding area."

Nidhogg immediately took off as Nathan summoned Jinwu.

"Jinwu. Check in that direction. There was a loud sound coming from that direction. If we couldn't find anything within five minutes of flying, it would be better to go back." Nathan explained.

To their surprise, there was nothing they could see in that direction, even though they had been flying for two minutes. He sent Jinwu forward because if there were powerful summoners, they wouldn't think much of Jinwu, as he looked like a normal crow from afar.

However, Nathan was wrong. All of a sudden, the earth-shattering sound once again shook the sky.

"!!!" Nathan's expression turned grim.

"The sound wave is traveling so fast…" Nidhogg turned his head around as if trying to follow the sound wave.

On the other hand, Jinwu returned to Nathan and explained, "I'm afraid we should stop here. If there is indeed someone capable of producing such a sound, going there will result in our death.

"Although I'm curious, it's better to survive. We better head back to the village if not go back to the Frexia Academy right now," explained Jinwu.

Nathan bit his lips. He fell into deep thought, wondering what he should do. On the one hand, Jinwu's advice was reasonable. On the other hand, there was something that bothered him. This sound was a bit weird, but he couldn't recall any information about it.

"Summoner!" Jinwu raised his voice as if he wanted to reprimand Nathan. Yet the sound wave once again shook the sky, which startled them. "Tsk."

"Nidhogg. Hurry up and bring them back."

"Yeah. I agree." Nidhogg nodded and turned around, not bothering to wait for Nathan's order.

One more time, the sound rang in the sky, which caused them even more panic, believing that there was such a powerful summoner.n/o/vel/b//in dot c//om

"Are we going to die or something?" Selena frowned.

"I'm not sure." Jinwu shook his head. "There's something weird about this sound wave. How do I say this… The sound wave is coming at the same interval, making me wonder if it's the same sound or not…"

"Same sound?" Nathan widened his eyes in shock, as though he remembered something. "That's right. It's the freaking same sound."

"What? Do you know anything?" Selena blinked her eyes a few times.

Instead of answering, Nathan looked down and fell into deep thought.

'What kind of thing can produce a sound so loud and powerful that it can travel the world multiple times? Is it related to the earthquake? Volcano?

'Is there a volcanic eruption… there is… I think I've heard or read this somewhere. After a certain novel used a volcanic eruption as a trope, I couldn't help but try to understand it a bit better to see if the author was bullshitting or not.

'That's right. I think I heard about it from the Play Button Tube about such a volcanic eruption. It was only surface-level information since I only used 8 minutes of my life to watch the video.

'There was one volcanic eruption from Indonesia that was so loud that the sound traveled around the world three or four times. How about the impact? Ash?

'I don't think it gave that information, but there was one eruption in the same century and in the same country. It was said that this volcanic eruption spewed so much ash into the atmosphere that that year is known as the year without a summer.

'Was the volcanic eruption similar to this one? The earthquake itself was quite huge, and it spread without anyone knowing the location.

'If that's the case, this is going to be hard. Is there any other possibility? A supervolcano?

'Now that I think about it, there is one more volcano from that same country… poor country getting bullied by volcanoes… Anyway, this supervolcano spews so much ash into the air that it basically covers the sky, preventing the sunlight from reaching the ground.

'As a result, the temperature decreases sharply. It should create a mini ice age lasting for a few years to a decade.

'If this is the case, the situation is much more dire than I originally thought. I just hope…' Nathan suddenly stopped when he recalled a certain dream.

It was the dream he had before this trip. A dream of him fighting against a lot of elite class aliens after climbing a small cliff.

In that dream, he remembered that the world was so cold and dark. More importantly, it rained ash.

'Is that not a dream but a premonition? The world is going to get covered by ash. And my master once told me about more dangerous aliens living deep in the alien's territory.

'If that's the case, having a lot more elite class aliens is pretty understandable.

'I can't imagine the impact this eruption can bring. I have read a lot of ridiculous tropes, like a continent falling from the sky, but a supervolcano?

'Fuck. What a way to actually start this shitty new year.' Nathan couldn't help but curse the current situation due to how bad it was.

He also noticed that the sound wave circled around the globe eight times.

While clenching his fists, Nathan looked at the three girls with a serious face. "Listen up, everyone. What I'm about to say is a secret, so don't tell anyone else first. Also, Nidhogg. We'll go back to the inn and immediately head back to the Frexia Academy. I will have to talk with my master after this."
