Senior Sister Faye's anxious expression disappeared as soon as their mentor Mosido and big Senior Brother Zoro entered the laboratory.
Mosido didn't look happy.
Even though he appeared cold and aloof to outsiders, Sain, who had followed him for years, noticed something different.
Senior Sister Faye had noticed Mosido's unusual behavior even earlier than Sain.
As someone who could sweet-talk Mosido and even ask for magic props, Faye had never seen her mentor look so serious.
Big Senior Brother Zoro, who followed Mosido into the lab, was also in a similar mood.
Fortunately, their mentor's and big Senior Brother's bad moods were not caused by Sain and Faye.
Seeing the two disciples who had been waiting for a long time and had already set up all the experimental equipment in the laboratory, Mosido sighed deeply and said.
"Sain, I have already arranged for half a year of leave for your mandatory academy mission. During this time, focus on studying and meditating to accumulate your mental power."
"Yes, mentor," Sain replied respectfully.
After giving instructions to Sain, Mosido turned to Faye and said, "Faye, you should also focus on your training. You have been stuck at the Advanced Apprentice level for over fifteen years. "
"Although you are not considered old in the Advanced Apprentice level, the underground world is about to undergo changes, and only sufficient strength can deal with all the crises."
Mosido's words made Sain and Faye serious.
"Crises" and "changes"?
What had happened?
While Sain was still pondering the meaning behind his mentor's words, Senior Sister Faye took the initiative to ask, "Mentor, is something about to happen?"
Faye's question and Sain's puzzled expression made Mosido's face even darker.
After a long while, he finally said, "Originally, only formal Dark Magicians of the first level were allowed to know about this matter."
"But since you are my disciples, I'll make an exception and tell you," Mosido said in a solemn voice.
"Three years ago, our airships sent to raid the Surface were targeted by someone."
"Every time our airships set out in the past three years, there were official Magicians and Knights opposing us."
"Last year, there were as many as six attackers, prompting Dean Dadalon to suspend the plan to raid the Surface this year."
"Earlier this morning, Dean Dadalon gathered all sixteen official Dark Magicians who were staying at the Dark Magic Academy and announced an early exploration of an alternate dimensional space."
"Since the message came too suddenly and due to the particularity of the Space-Time Rift on the other side, you Dark Magic Apprentices are the ones to go first to explore and help the academy bury a corresponding coordinate generator at the other end of the Space-Time Rift."
The amount of information in Mosido's words caught Sain and Faye off guard.
For them, who were only at the apprentice level, terms like "alternate dimensional exploration" and "Space-Time Rift" were too advanced.
Even the public library at the Dark Magic Academy had almost no content on this subject, which should have been intentionally hidden by the official Dark Magicians.
The mention of the airship being attacked by Mosido also indicated that there was an enemy lurking in the underground world and the academy.
Were they the Magicians on the Surface? And what about those official Knights...
While Sain was still digesting this information, Senior Sister Faye quickly said, "Did the dean suddenly decide to explore that alternate dimensional space early because of the airship attack?"
"If so, why didn't the academy just take out those attackers? Just six attackers..."
There were many Dark Magicians in Mosobla City.
According to Mosido, there were only sixteen official Dark Magicians who stayed at the academy, not to mention the powerful dean and other hidden forces.
Only six formal magicians and knights from Surface posed a threat to Mosobla City, which should have enough strength to fight back or even eliminate them.
Facing Faye's inquiry, Mosido didn't feel relaxed at all.
"Just because there are only six formal magicians and knights on the surface, who knows how many more are lurking in the shadows?"
"After all, the Wizard Continent is not a place where we Dark Magicians can run rampant. There are so many Holy Towers and Knights' Halls here..."
Mosido shook his head and said, "After this space-time exploration can be successfully completed, I will take you back to the Western Islands."
"Work hard. Although we need to borrow the power of your apprentices this time, whoever enters that Space-Time Rift at the beginning must be at least a semi-magician."
"We won't conduct any experiments today. You all go back and practice well. I have something to discuss with your senior brother." Mosido waved his hand.
After leaving the mentor's laboratory, Sain and Faye lost interest in doing anything.
After a brief chat, they parted ways.
Faye went directly to the apprentice dormitory, while Sain planned to visit the public library first.
Although he had never seen how many books on the subject of parallel worlds were in the public library before, he had a lot of Integral Points at the college.
If he searched carefully, he might find something.
...
"Plane, an independent and complete world in the star realm."
"The most common are the half-planes and the broken planes, while the relatively rare ones are the rule-complete planes that can nurture intelligent races and give birth to civilizations."
"These rule-complete planes are divided into different categories based on their power levels and overall strength..."
Sain looked at the torn page of the book titled "Microcosmic Elements" and sighed softly.
After putting away the antique book, Sain looked at another book called "Markobian Odyssey."
"Markobian Odyssey" records the story of a formal magician traveling to a parallel world named Centauria.
Although Sain couldn't figure out what level of world Centauria belonged to from the book, he could tell from the words and between the lines that Centauria was a parallel world completely ruled by the Wizarding World.
Markobius, a magician of the Wizarding World, enjoyed a high status and some privileges while traveling in Centauria.
He even had deep conversations with several female centaurs during his journey.
"Microcosmic Elements" and "Markobian Odyssey" were the only two magic books Sain found in the public library of the academy that recorded some knowledge and situations about other dimensions.
Although some other magic books also had some brief mentions of other dimensions, most of them only casually mentioned it.
The useful information was not as much as these two books.
"Centaur, what kind of creature is that? From the descriptions in the books, it seems similar to the Minotaur?"
"But the Minotaur is a man with a bull's head and a human body, while the Centaur seems to be a human head and a horse's body?"
At night, lying in bed, Sain couldn't help but sink into deep thought.
Lena didn't come back today, probably due to some experiment with Master Ferena, which was at a critical stage.
Sain couldn't share the news he had just received from his mentor with Lena, otherwise, with her intelligence and insight, she could provide some advice to Sain.
