Although Aldebaran didn't possess high intelligence, it certainly understood pain. Being attacked like this hurt immensely. Even though it could regenerate quickly, it couldn't withstand the agony of being repeatedly blasted apart.
A massacre against the Gastrea unfolded right then and there. Ren Isana's classmates, along with the seniors, began a one-sided slaughter against the monsters.
Everyone watching through the satellites couldn't help but feel a chill down their spines. To the people of this world, Gastrea were creatures of terror—the natural enemies of humanity.
But now? In the face of absolute strength, those Gastrea were like paper, shattering upon the slightest contact. This display of power left everyone dazed and confused.
At the same time, many grew suspicious. What exactly was going on? At this moment, everyone was curious and bewildered. What was happening in the Tokyo Area?
Where did this group of people even come from? Before Ren Isana's battle was even over, Seitenshi began receiving a constant stream of communication requests from various other regions.
However, Seitenshi rejected them all. She looked at the battle footage on the screen with a complex expression. Most likely, after today, the existence of Ren Isana and his group could no longer be kept a secret.
At this moment, Ren Isana landed on the Monolith. He sat there, watching the others battle below. Not far from him were his classmates, Sayaka Kirasaka and Kumo.
Kumo had nearly exhausted her Magic Power. After leaving herself a small reserve, she came over to sit beside Ren Isana. Exhaling a breath of turbid air, she couldn't help but ask, "Class Rep, aren't you going to join in?"
Aside from dealing with Aldebaran initially, Ren Isana hadn't made another move. He had just been quietly watching, allowing the students below to fight without any intention of intervening.
"I'll leave this Excelia to all of you. If I act, the battle will be over in an instant," Ren Isana replied with a calm glance.
This wasn't a boast; it was absolute confidence. After all, killing Aldebaran would be an incredibly simple task for him. Kumo didn't doubt the truth of his words for a second.
She turned her head toward the Gastrea below and said with a hint of regret, "Unfortunately, my Magic Power is consumed too quickly. Class Rep, do you know if there's any way to increase my capacity?"
Her talent was total elemental mastery, and she had even obtained [Instant Cast]—a magic that functioned like an innate talent—while in the Dungeon. But because of this, her Magic Power was constantly insufficient.
In the [Instant Cast] state, she could only maintain a continuous bombardment for a few minutes before running out of Magic Power. While her firepower was immense during those minutes, it wasn't enough to satisfy her.
Therefore, Kumo was now desperate to find a way to raise her Magic Power limit. As long as she had enough energy, she would be the most powerful magic turret.
Listening to Kumo's question, Ren Isana fell into thought. "A way to increase Magic Power... for that, you can only rely on Intermediate Potions, but that kind of increase is probably limited. The best solution would be for you to create a permanent magic spell capable of storing Magic Power."
Ren Isana understood Kumo's situation perfectly. Even if she could increase her limit slightly, it would only be a marginal improvement. It wouldn't help much since [Instant Cast] simply consumed too much Magic Power.
Kumo nodded, saying with a troubled expression, "But if I don't increase it, I can't fully utilize the advantages of [Instant Cast]."
Her Magic Power reserves were about the same as her classmates, and even her recovery speed was similar. She was already trying her hardest to train her magic recovery speed.
But it was still too slow and couldn't meet her needs. Ren Isana just said she needed a permanent spell that could store Magic Power? That was a good lead.
However, she was at a loss as to how to begin. Kumo couldn't help but look at her omnipotent Class Rep. Ren Isana had created spells before, so according to what he said, he should have some ideas, right?
"Class Rep, do you have any thoughts? Regarding magic storage." She had spent a lot of time with Ren Isana and understood his personality well; if you needed something, it was best to just ask directly.
If you tried to be indirect or talk in circles, he might actually get annoyed. In Ren Isana's words: *What are you babbling about? Can't you just speak human!*
"Actually, I do!" You don't say, but as soon as the topic came up, ideas began to surface in Ren Isana's mind. Moreover, completing it would be quite simple for him because he had essentially done it before.
"Details, please!" Hearing this, Kumo's eyes lit up. Her gaze was full of surprise and admiration. As expected of the Class Rep—he really did have a plan.
"Take the [Weapon Storage] magic. The essence of that spell is to construct a small space and stuff weapons into it. Essentially, the weapons are thrown into a void, and the marks on them are coordinates. Every time we pull a weapon out, we're using those coordinates," Ren Isana explained slowly.
This magic storage idea was quite similar to his own heart space, only it needed a little modification. That was why he said he had already developed something like it.
Although Ren Isana's special space was for storing items, it could be modified to store Magic Power instead.
Kumo was stunned as she listened to Ren Isana's explanation. The [Weapon Storage] spell? As he continued, the principles of the magic began to take shape in her mind.
"What if we anchor the space used for storing weapons and use it to store your own Magic Power? Essentially, both your marks and your Magic Power come from the same source. As long as you construct a Magic Power transmission channel, you can store the Magic Power you aren't using and draw it out when needed," Ren Isana said in one breath.
This thing was actually quite similar to the Yin Seal of a certain Fifth Hokage. Though in this world, it should probably be called 'Magic Storage'.
Kumo began to conceptualize the idea as Ren Isana spoke, but she soon encountered a problem, leading her to ask, "But how do I construct that kind of space?"
She wasn't skilled in [Spatial Magic], and that point alone was enough to stump her. She understood the method Ren Isana described, but the actual operation was the issue.
"The human heart is the path through which Magic Power must flow. Carve a [Magic Mark] for a space into your heart, and then construct a separate transmission channel. Treat it as a backup Magic Power source," Ren Isana didn't explain the difficulties; instead, he continued to voice his ideas.
Once he started thinking, he couldn't stop. If he didn't say everything at once, he'd feel uncomfortable.
Kumo didn't rush to interrupt with more questions. Instead, she continued to listen intently because this theory truly had the potential to solve her problem.
In fact, if it succeeded, everyone could create a second Magic Power source. Who wouldn't be afraid of someone with two mana bars?
This would be an immense help to a mage, especially for someone like her who possessed infinite firepower. If she could really open it up...
"Once the channel is constructed, you can extract Magic Power at any time. However, how to form that space inside your heart to store Magic Power is the problem. Unlike a weapon, Magic Power might dissipate if you just stuff it in," Ren Isana said, and by this point, Kumo understood.
That was the biggest issue: how to store the Magic Power and how much it could hold. Regarding the construction of a magic channel, Kumo already had some ideas.
But opening a space and storing Magic Power were the two problems that blocked her. Oh, no, wait—there was also the issue of how to place a mark on her own heart. She couldn't exactly perform surgery on herself, right?
However, if it could be in the heart, it could presumably be on the skin as well? But wouldn't that be too dangerous? Even if it succeeded, a mark on the skin would need extreme protection.
Otherwise, if someone hit you there, your Magic Power might go berserk and you'd likely die on the spot. Placing it somewhere others couldn't reach was undoubtedly the best choice—like the heart.
"Hiss... so Class Rep, because the heart isn't easily attacked, and if someone does hit it you're dead anyway, you chose to put the magic storage there?" Kumo instantly realized Ren Isana's reasoning.
Ren Isana nodded. "Exactly. After all, this is just a giant battery. If your heart is pierced, you're definitely going to die, and the Magic Power source will explode along with it. That way, you can even take your enemy down with you!"
"Hmm... now that I think about it, it could also be used as a last resort. If you encounter someone you can't beat and you're going to die anyway, you can just detonate the stored Magic Power to take them with you," Ren Isana's eyes lit up as he spoke.
Wasn't this just a self-destruct magic? If a massive amount of Magic Power was stored inside, and they met an unbeatable foe...
Good heavens, they could pull off a one-for-one trade. Dragging the enemy down with them even in death sounded pretty good.
Kumo shuddered as she heard Ren Isana's words. The Class Rep was so ruthless, actually thinking about dragging people into a self-detonation? But on second thought, it really was feasible.
"But... how do we place the mark into the heart? And the part about opening the space..." In the end, it all came back to these questions.
"Let me think. If it were Yukino, her talent could do it. But for your talent... you'd need to create a [Perception Magic] for internal vision... actually, you might not even need magic. True Qi can do that as well?" Ren Isana fell into contemplation.
He began to construct a method in his mind that others could use. There were only three people on the Monolith, and Ren Isana's conversation with Kumo was heard in its entirety by Sayaka Kirasaka.
By now, she had stopped attacking the Gastrea below. Instead, she looked at Ren Isana with a bizarre expression. Was this Class Rep's way of doing things always so wild? Someone asks a single question, and you just hand over a complete solution?
Wasn't this a bit too ridiculous? Sayaka Kirasaka was truly witnessing the absurdity of Ren Isana's brilliance today.
Seeing Ren Isana lost in thought, Kumo didn't disturb him. She turned to look at the battle below. The ground was already flowing with rivers of blood, though it was all from the Gastrea.
"Kumo, how are you? Are you recovered? Do you want to come down?" Just as Kumo looked down, the [Magic Mark] on her hand chimed, and Sora's voice came through.
Hearing Sora, Kumo replied, "I won't be coming down. I was just discussing ways to increase Magic Power with the Class Rep. He gave me a lead, and now he's thinking about how to implement it."
Sora immediately became interested and started chatting with Kumo while continuing to fight. Kumo didn't hide anything and shared Ren Isana's ideas with her.
She even mentioned the part about using it for self-destruction. Her words reached the ears of everyone through the [Magic Mark], and the group was stunned.
Ren Isana's idea was truly outrageous, but thinking about it made their hearts race. Wouldn't this be another trump card? If it could be realized, everyone would want to learn it. They just hoped it wouldn't be too difficult!
After all, many of them hadn't even fully mastered [Flight Magic] yet. This new concept involved both space and magic storage—it sounded like a very troublesome project.
Not to mention, it seemed like something others couldn't help you with. Plus, it involved the heart... If you thought about it, even if Ren Isana really developed it, it would likely be 'Hell Mode' difficulty.
"True Qi can sense the state of your own body. Combined with the assistance of Magic Power, you can fully see your internal organs. You just need to use [Perception Magic] for it," Ren Isana spoke up at that moment.
He already had an idea. He might not be able to make others like Yukino, who could control every bit of energy in her body, but achieving the ability to see one's own heart or other organs was easy.
Hearing this, Kumo's spirit was roused. Sayaka Kirasaka stopped her attacks entirely and sat down next to Kumo, prepared to listen to Ren Isana's plan. This was much more interesting than a teacher's lecture!
"As long as you can observe your heart, then controlling Magic Power to place a mark shouldn't be a problem. Consider that issue resolved, then?" Ren Isana looked at Kumo.
Kumo nodded. If that could be done, the problem was indeed solved. The biggest hurdle was the inability to see the heart's condition; if Magic Power ran wild inside, it could kill you.
"Once the mark is placed, it can be maintained by connecting it to the flowing Magic Power source in the heart, just like the marks we have on our hands," Ren Isana said, showing the [Communication Magic] mark on his own hand.
Kumo visualized the situation. As long as you occasionally activated it with Magic Power, the mark would persist. If you didn't activate it, it would vanish after seven days.
But a mark in the heart would be bathed in Magic Power constantly. Thus, once placed, it would never disappear. This was perfect. Kumo nodded, her eyes shining.
"With that done, the remaining issue is the stability of the space within the mark. We wouldn't want your heart to be accidentally teleported away—that would be quite the spectacle. For things involving space, I'll have to consult Natsuki later; she's the expert in that field." Ren Isana stopped there, not saying anything more.
He had given her the logic. The remaining problems of spatial stability and the method of storing Magic Power were things she needed to figure out herself. If Ren Isana wanted to do it, he could just modify his own space or open a new one.
However, there was no need for him to do so. Ren Isana's Magic Power was inexhaustible—truly endless. His recovery speed was so fast that the day he actually ran out of power would never come.
"Mm... I'll ask Natsuki when I go back. I can start by researching the storage method first." After hearing Ren Isana's words, Kumo nodded. She had the complete logic now, and it seemed very feasible.
This was already more than enough for her. She would solve the remaining difficulties herself. Perhaps this was an assignment Ren Isana was leaving for her? After all, if the Class Rep did everything for her, what would be left for her to do?
With that thought, Kumo made up her mind. In the coming days, she would properly research Magic Power storage methods. Once that was solved, she could ask for a way to stabilize space, integrate the storage method, and finally build the transmission channel to complete the spell!
"Would this count as Advanced Magic?" Sayaka Kirasaka spoke up. If this spell truly succeeded, wouldn't it be at the level of Advanced Magic?
After all, it involved so many things. To carve a mark, you'd need to be able to externalize Magic Power, right? That was something only Tier 5 mages could achieve, and it was a technique required for many high-level spells.
Kumo was momentarily stunned by Sayaka Kirasaka's words, but she soon relaxed. She nodded and said, "It truly is in the realm of Advanced Magic. In fact, it's an entire system..."
But Kumo didn't mind. Tier 5 was all; she would reach it soon. As long as this magic could succeed, it wasn't a problem!
"If you had Yukino's talent, you wouldn't need to be Tier 5. You could even do it at Tier 3," Ren Isana smiled at the two. Yukino's talent had an absolute advantage in this regard.
The traits of high-tier mages were nothing in front of her, because her talent allowed her to do things that usually required being a high-tier mage.
The two were left speechless. They didn't have Yukino's talent, so it seemed they could only wait until Tier 5 to try it.
"I'll post the technique for seeing your internal organs in the group chat later. You can study it yourselves. In the future, you can use it to check your own body whenever you want—see if there's anything wrong with your heart or kidneys. You could even take a look at your own child once you're pregnant?" Ren Isana chuckled as he spoke.
Kumo and Sayaka Kirasaka were left completely speechless. What in the world? Take a look at your own child? What kind of skill was this? A 'Human Self-Check'?
