"That's how it happened."

In the dean's office, the students of Class VII. who had been summoned reported the incident to the dean who had arrived temporarily.

"To the elevator deeper underground... I didn't expect such a thing to appear. The head of the house, who had heard the report, muttered deeply.

"When I was on the shift a week or so ago, I remember that there really wasn't that kind of thing." Sarah frowned, "Hmm—I always feel like I've been tricked." ”

"And the old school building still seems to be going underground." Rien interjected, "Although this time it seems that you can't go down any further when you reach the second layer. ”

"It turned out to be a mystery too... There doesn't seem to be a need to unblock it. Alyssa added.

"Where, how many floors does the old school building last to the basement?" Elliot, the orange-haired boy, spoke.

“。。。 No, basically, I haven't heard of any deeper floors in the past few decades. The head of the house replied, "Until last month, I remember that there was only a floor for orienteering adventures. ”

"That is, did it appear out of nowhere?" Brown-haired boy Gaius jacked.

"And there is also an obvious way to move the elevator." Laura answered, "It's impossible to understand how to say that it's a relic of the 'Dark Ages'. ”

“。。。 Ike, did you find anything? The Headmaster was silent for a moment, then turned to look at Ike.

"The first is the structure of the floor." Ike replied, "Structurally, the area below ground is obviously much larger than the area of the old school building above ground, and it really doesn't look like a modern work in terms of the age of the building, and the guide light can continue to illuminate until now without anyone repairing it, which is simply not possible with current skills." Ike replied, "The second is the magic element, and the further down the level, the stronger the magic element becomes." Although there is no higher-level attribute yet, it cannot be ruled out that the influence of lower-level attributes will be greater, and I speculate that this old schoolhouse should be built on the elemental root ground. ”

"Roots?" Li En asked suspiciously.

"The magical element of this world does not appear out of thin air, but is an energy generated by this continent after countless years, and this energy is often buried deep underground, and accidentally leaks out after experiencing changes in the earth's crust. And among the land that gives birth to these powers, there is one of the most abundant places, which is also the place where the energy was first born, and we are used to calling this place the root place, and all the power is generated from these root places as the starting point. The dean replied.

"And these energies, because they come out of the ground all year round, have experienced tens of millions of times high pressure during the deep burial process, which has caused large-scale morphological changes in the originally invisible energy, and evolved into the dale crystals you are using now." There was a hint of gloom in Ike's expression, which was quickly disguised, "And these roots... Well, in layman's terms, it should be called - flare crystal veins are more appropriate. ”

"Dazzling Crystal Mine?!" Everyone couldn't help but be surprised, in today's rapid development of the Guiding Revolution, the importance of a flare crystal vein does not need to be explained, everyone knows the value of it.

"Impossible!" Alyssa stepped forward and shouted, "If there were a vein of dazzling crystals here, the people in the past would have discovered it a long time ago, right?" It would be strange to build a building that deep into the ground on a vein if it hadn't been discovered yet. ”

“。。。 Maybe it's something to do with the 'Draekers the Great'. The headmaster, who had not said a word, suddenly spoke, his calm eyes with a sagtic glint in them.

"The Lionheart Emperor?" Alyssa asked.

"Well, since the establishment of this academy, each generation of academy directors has passed down the emperor's 'certain words' among each generation of academy heads." The dean replied, "Keep that building, the old school building, well preserved until the 'coming day' comes." ”

"The day that is coming ... What does this mean? Elliot was puzzled.

The meaning of this sentence is still unclear. The head of the house shook his head regretfully. "There are also those who claim that it is related to the 'Battle of the Lions' 250 years ago and the 'Holy Lady Sandrot'."

"The Saintess of the Gun – Liana Sandrot... Is it? Ike muttered softly with all sorts of complexity in his eyes.

"In the era of the 'Lion Battle', the warriors who led the 'Iron Cavalry' to gallop on the battlefield with the Emperor. There is still a statue of her in my hometown, and it is said that the Church of Nanyao also recognized her as a saint. It should be a hero that everyone knows in the Empire. Laura answered.

"Even in my hometown, which is on the border, the name is sung." Gaius answered.

"There are indeed all sorts of legends and mysteries about the Holy Maiden ... In other words, does that have anything to do with the old school building? ”

"It's not certain. However, the recent change has no way to say that it has nothing to do with what the Emperor said in the past. The dean replied. It's just that we can't understand anything based on the current clues, and we still need to search for it. ”

"yes, we'll search again if we have the chance." Lane sighed helplessly.

"Thank you, Class VII, but you're only students now, so please be careful when searching. I thank you from the bottom of my heart. The dean replied sincerely.

"No, no, no, no! It's a pleasure to help. Elliot replied hurriedly.

"We will report what the investigation finds in the future as soon as possible." Lane nodded, "Then, let's take our leave." ”

"I'm sorry for you." The Dean stood up and replied. watched the crowd leave.

"Everyone, thank you for your great help." Closing the door to the dean's office, Rien turned to Alyssa and the others.

"Don't worry, since you've been involved so much, of course you want to solve the mystery." Alyssa replied.

"yes, it seems to be a good cultivation." Laura nodded. "When you want to search that place again, you can call me at any time."

"I see, thank you all again." Lane replied gratefully.

“。。。 Sarah-sensei? What are you thinking? As he was about to leave, he suddenly saw Sarah holding her chin in thought, and Elliot asked puzzled.

"Hmm—I always feel like I'm going to remember something, but I don't have a clue at all." Sarah said a little irritably, "Ahhhhh ”

"Are you thinking about something? Sarah, a teacher. Rien interjected.

"It's just the topic, and I always feel like I've caught some clues. But I can't seem to remember. Sarah replied with some annoyance.

"Clues? Is it from the old school building? Rien asked.

"It's not, it's about ... Concerning... Right! That's right! It's about the Holy Maiden of Guns! Sarah suddenly excitedly amplified her voice, "The Saint of the Spear's direct subordinate troops, Iron Cavalry!" ——”

The voice stopped abruptly, and he turned his head to look around with an incredible look, and in the place that originally belonged to someone, Ike's figure had long since disappeared into the crowd of Class VII, and only Sarah's muffled voice remained in the air.

"Iron Rider... Iron Fleet... ”
