Everyone looked concerned. After knowing what happened, Sera became a bit calmer.
"Do you know anything?" Flora asked her Earth Spirit. The latter shook its tiny head. Flora fell into deep thought. "What should we do then?"
Thompson raised his head. "I will talk to the investigation and provide them with this information. Since it's from the Ancient Library of the Fairy Queen, it should be pretty credible. We will proceed with that information in mind."
Nathan pinched the bridge of his nose. He thought this mission would end after they killed some aliens. However, they were wrong.
Flora turned to Nathan. "I'm really glad that I brought you here. I know you're useful."
"Before thanking me, I think we should go right away." Nathan shook his head.
"Go? Where?"
"The mine. This kind of earthquake will cause a huge mess over there. They might need our help, especially to rescue the miners."
"Ah!" Flora gasped in realization. She immediately said, "Yes. We'll go there immediately. Mr. Thompson!"
Thompson nodded. "Alright. Make sure you don't do anything dangerous. If it's not possible, retreat immediately. We can't explain to the Azilia Kingdom if something happens to you."
Flora acknowledged his words and waved to Nathan, signaling him to go.
Nathan rose from the ground, helping Sera, who gradually calmed down.
"Thank you, Nathan. The situation becomes clearer after your information. I never thought you would have all that information. I'm really speechless." Flora smiled. "I'm really glad I brought you here."
"Still, we haven't figured out what causes it. There's a chance an alien might cause this as well." Nathan shrugged, thinking, 'In this kind of world, anything can happen. In fact, the aliens we're facing can survive in outer space, right? What if they end up sending a huge meteor to this world... Like the meteor that caused the extinction of the dinosaur?
"There's a volcano underwater? Doesn't a volcano have magma in their belly? If it's inside the sea, doesn't that mean the magma is fighting against the sea all the time? How's that going to work? There was once an experiment that dumped a huge amount of water into the volcano, but the water instantly evaporated and caused a steam explosion. If there's an underwater volcano, won't the sea heat up or even evaporate entirely?"
Nathan scratched the back of his head. "I don't know much. I read those books, not understand them."
"Fair enough." Flora nodded.
"Anyway, I'm just pointing out another possibility. It's, by no means, the truth."
"Yep." That possibility made her fall into deep thought. "Does this also make the sea god angry?"
"Sea god?" Nathan tilted his head in confusion but soon linked to another disaster. "Tsunami?"
"Tsunami?" She tilted her head in confusion.
"Yeah. If this earthquake happens underwater, it can cause a tsunami according to the book. This tsunami I'm talking about is a high wave that carries a lot of energy. It can sweep away an entire city near the ocean with ease."
"Yes. That! To think the Ancient Library also has that kind of information." Flora shook her head helplessly.
Nathan couldn't help but wonder what she would do if she knew it came from a novel from another world. And what would her response be if she knew that the master of the Ancient Library would be summoned to this world again through his master? He ended up with a headache.
However, that headache became even more serious when they reached the site.
"Nathan..." Flora gasped. They could see the mountain the Blacksmith Guild was mining. There was a colossal mature class alien leading hundreds of aliens.
A group of fighters seemed to be resisting, but with that number, they couldn't really do much.
Nathan scanned the area and said, "Sera and I will take care of that mature class alien. You should handle the rest of the aliens and rescue those people. If possible, find the supervisor and coordinate with them. There's a chance another mature class is among those aliens but with a smaller size, so this is much more suitable for you since you won't die easily from a sneak attack.
"And you have the authority of the group, so you should go." Nathan didn't wait for her reply as he commanded Nidhogg. "Go."
