They didn't dwell on the matter for long, as their attention quickly returned to the battlefield. Once the topic was dropped and the two had caught their breath, they stood back up and resumed their assault.
Ren Isana watched the battle below in silence, having no intention of intervening. As the fight raged on, the number of Gastrea corpses continued to pile up, prompting Seitenshi to dispatch a cleanup crew to the area.
However, these people weren't there to fight. While Ren's classmates were slaughtering the enemy at the front, the dispatched civil security officers were busy clearing the aftermath from behind.
The battle continued to intensify as more monsters fell, and the students pushed further into the horde.
The cleanup crew moved efficiently, ensuring the path was clear for the advancing fighters.
While Ren Isana was watching the show from atop the Monolith, someone else arrived. A helicopter flew near the Monolith, and two figures leaped from the cabin.
A flash of surprise crossed Ren Isana's eyes when he saw them. Once they landed safely and approached him, he couldn't help but ask, "What are you two doing here?"
Hearing his question, Miori Shiba giggled and immediately explained, "To watch the live broadcast in person, of course! Although we can watch via satellite, it's nowhere near as impactful as being here on-site."
With that, Miori Shiba sat down next to Ren Isana, followed by Kisara Tendo. Ren Isana looked at them, somewhat speechless. After a moment of thought, he spoke up. "If you have nothing better to do, you can prepare to head over to my side next."
Ren Isana brought up the matter directly. Miori Shiba's eyes lit up instantly, filled with pleasant surprise. "I can go over now?" she asked, her voice trembling with excitement.
Kisara Tendo, on the other hand, found it a bit hard to believe. Could she go too? Was he serious? For a moment, she was filled with doubt.
"Of course. I have no reason to lie to you. If you're finished with your business here, I can send you over. You'll need to attend school there; there's a dedicated academy for people from other worlds, specifically designed for those like you to learn," Ren Isana explained, giving them a brief overview of the situation.
Listening to this, both girls became energized. They were incredibly eager to learn knowledge from another world, especially Miori Shiba, who had already come into contact with magic and was actively studying it.
She had been practicing [Meditation] for several days now, but the Magic Power she possessed was still insufficient to cast even the weakest spell. She was currently in the process of accumulating more energy.
If she could truly study in another world, it would be an incredible opportunity for her. Moreover, she had the ambition to expand her family's heavy industry into the other world as well.
Before that, she needed to understand the environment there, so the earlier she went, the better. Ren Isana bringing this up now was nothing short of a massive, pleasant surprise.
"That's the general situation. So, if you want to go, start preparing. Once things are settled here, I'll send you over," Ren Isana told them.
Seeing this, Kisara Tendo couldn't help but raise her hand and ask, "I can go too? There's a spot for me in this?"
She wanted to be sure. She thought perhaps Ren Isana had misspoken, as he had never mentioned this to her from the beginning, and she had never even considered that she would be allowed to go.
"Of course you can. If you don't want to, you don't have to. Regardless, that school is prepared for people from other worlds. If you want to study there, I'll just have my teacher arrange it for you," Ren Isana said with a casual air.
Kisara Tendo's eyes brightened upon hearing his words. Her great revenge was already satisfied, and her physical issues had been completely resolved. As a healthy woman, she naturally wanted to learn more and grow.
She could finally have a life of her own. As for the Tendo Familia behind her? Kisara Tendo never cared whether they lived or died, even though she was currently the head of the family.
She had no affection for the remaining members. Since she had taken over the Tendo Familia, quite a few people had jumped out over the last few days, claiming they were the 'orthodox' successors.
It was hilarious. If she hadn't been cooperating with Ren Isana's plans, she would have killed those fools long ago. They had zero talent but acted as if they owned the world; it was truly pathetic.
"Fine, then I'm going. I'll go back and settle the Tendo Familia's affairs in a bit. A family like that should just be dissolved. I'll donate all the Tendo Familia's assets to Seitenshi!" Kisara Tendo decided on the spot.
Those guys wanted the Tendo Familia so badly? Fine, she would give the assets to Seitenshi. If they wanted them, they could go ask Seitenshi themselves—if they even had the guts!
Ren Isana's expression turned quite strange when he heard this. That was certainly one hell of a gift for Seitenshi, considering how rich the Tendo Familia's resources were.
However, he didn't care what she chose to do. Instead, he offered a reminder. "Even if you're giving it away, make sure to keep some money for yourself. Cultivation on our side costs money, and you'll need equipment and such. It's best to have some funds prepared."
He left it at that; what she did was her own business. Kisara Tendo nodded, understanding his point. She would go back and liquidate the assets immediately.
"Our world's currency won't work on your side, right? Antiques and paintings probably won't be in demand either. So, is there any hard currency?" Kisara Tendo asked.
"Gold. If you want to exchange for money, it's best to bring gold. Or perhaps some rare metals." These were the universal hard currencies on his side because gold was useful in almost any world.
As such, its price remained stable, and trade with other worlds was often conducted using gold as the primary currency. "Gold? I understand! I'll have my father start collecting it immediately. We'll hoard as much gold as possible while we can." Knowing it was hard currency, Miori Shiba's eyes sparkled.
Without a second thought, she pulled out her phone and called her father, rambling on about how he needed to gather gold for their future in another world.
Due to the apocalypse, gold wasn't particularly valuable in their world. Its price had remained low because it wasn't circulating well, meaning it lacked significant utility.
Now that it was needed on Ren Isana's side, it suddenly had immense value. They needed to collect it quickly; there was even a chance they could make a profit if the price started to rise later.
Seeing this, Kisara Tendo also began making arrangements. There were still a few usable people in the Tendo Familia, and since she was the head, people naturally flocked to her. She simply ordered them to handle the liquidation.
She instructed them to start buying up gold in the market and even used the Tendo Familia's influence to snatch up gold from other regions. Once both women had finished their arrangements, they returned to Ren Isana's side.
Miori Shiba looked at the Gastrea corpses below and couldn't help but ask, "Are you using Aldebaran to lure Gastrea here to be killed? How much longer will this go on?"
Looking at the piles of corpses, she felt numb. These people from another world were conducting an absolute massacre. Just cleaning up all these bodies would take an eternity.
Seitenshi was going to have a massive headache. For several kilometers, there was nothing but corpses. It had reached the point where there was no place to even step; if you wanted to move, you had to tread on the remains of the Gastrea.
Standing on the Monolith, they could smell the thick, overpowering scent of blood. Anyone with a weak constitution would likely faint upon seeing such a scene.
Had they ever seen a river of blood? They were seeing one now. As the Gastrea corpses piled up, their blood converged into small streams, eventually flowing toward the lower ground and forming a crimson river.
"It's about done. Most of the Gastrea in this area have been dealt with. It's time to handle that big guy as well." Ren Isana observed the situation closely after hearing Miori Shiba's words.
Fewer and fewer Gastrea were approaching now. Since that was the case, the 'big guy' had served its purpose. Moreover... Ren Isana had already completely figured out Aldebaran's method for summoning Gastrea.
Ren Isana could use that method himself now, so keeping the creature around was useless. It was better to just finish it off. If he needed to summon Gastrea in the future, he could do it himself, likely with even greater efficiency.
Miori Shiba was stunned by Ren Isana's statement. She was about to say something when she saw him drop straight down. After a period of free-falling, he took flight and began heading toward Aldebaran.
Seeing this, Miori Shiba and Kisara Tendo immediately grew excited. The real show was about to begin! They had seen Ren Isana blast Aldebaran away before, so now that he was going to finish the job, an even more terrifying power was bound to erupt.
Seitenshi and the others also noticed Ren Isana's sudden movement, and everyone's spirits rose. Once he reached a certain distance, Ren Isana stopped and pulled out his magic staff.
Seeing Ren Isana in the sky, Aldebaran became visibly restless. Its entire body writhed as it tried to break free from the massive block of ice, even attempting to command other Gastrea to attack Ren Isana.
Just as Ren Isana produced his staff, a laser beam shot toward him from a distance. Fortunately, his reactions were lightning-fast; he raised a hand and instantly deployed [Protection Magic].
The laser was easily blocked. Ren Isana looked at Aldebaran, the corners of his mouth curling into a slight smirk. An invisible force radiated from his body, instantly disrupting the pheromones Aldebaran was emitting.
The students below also noticed Ren Isana in the air. Was he finally going to make a move on Aldebaran? Everyone immediately accelerated their actions, clearing out every Gastrea in sight.
If they didn't hurry, there wouldn't be any more Gastrea being summoned once Ren Isana killed Aldebaran. Or rather, had it already started? Everyone noticed that some Gastrea were already turning tail and fleeing in terror.
Once Ren Isana interfered with the pheromones, the surrounding Gastrea were no longer being manipulated. Without the pheromone interference, the pungent smell of blood immediately terrified them.
Their biological instincts took over, and without the external control, they began a frantic retreat. Ren Isana didn't pay any mind to those Gastrea. After this, it was unlikely any Gastrea would return to this area for a very long time.
"Class Rep, can I live-stream your next move?" Asagi Aiba's voice rang out. Hearing this, a flash of surprise crossed Ren Isana's eyes.
However, he quickly understood her intentions and gave his consent. "Go ahead and stream it. It's good for the commoners to see, and those children too. Tell them if they want to learn magic, they should come here."
Asagi Aiba nodded. She operated her equipment with rapid precision, and a moment later, her voice rang out again. "It's all set. Go for it! I've started a forced broadcast."
As soon as she finished speaking, every television in the world with a signal was forcibly switched to the satellite feed. The footage was taken from high altitude, so Ren Isana's face wasn't visible.
The resolution wasn't high enough for that. All people saw was a figure flying in the sky and a literal river of blood below—everywhere the figure passed was covered in Gastrea corpses.
Many people turned pale at the sight. What on earth was this? The average person was stunned by the sheer brutality of the scene. What kind of broadcast was this!?
However, the next image to appear left everyone completely speechless. They saw the figure in the air slowly raise his staff and point it at the colossal Gastrea.
In the next instant, a [Magic Circle] appeared. That's right, a [Magic Circle]. A massive formation generated, expanding to dozens of meters in the blink of an eye.
The students fighting below suddenly felt a surge of Magic Power from the sky, and they were all startled. Looking up, they saw the borderline-absurd [Magic Circle].
"Good grief, how much Magic Power does that take? Does the Class Rep really have that much?" Looking at the [Magic Circle], everyone felt like their minds were breaking. This was simply too terrifying.
Without hesitation, the students scrambled to get further away, fearing they would be caught in the aftermath. Meanwhile, Aldebaran became even more frantic, sensing the imminent approach of death.
Unfortunately, the prison Ren Isana had constructed for it was too strong. No matter how much it struggled, it couldn't break free from the freezing spell he had placed upon it. At that moment, Ren Isana's [Piercing Magic Cannon] was fully charged. Looking at the distant Aldebaran, he launched his attack. A terrifying amount of Magic Power converged into a massive beam of light that descended from the heavens.
Boom! A colossal mushroom cloud rose into the sky as terrifyingly high temperatures began to vaporize everything in their path. The explosion instantly vaporized Aldebaran; even with its monstrous regeneration speed, it couldn't possibly recover from such overwhelming power.
Ren Isana didn't even need to use special metals to suppress the Gastrea Virus's regeneration. Why bother with metals when high heat was so effective?
As long as the temperature was high enough, any virus would be vaporized. Did they not understand the concept of high-temperature sterilization? In the face of absolute power, a virus was nothing more than a joke.
The other students had long since ducked for cover. They shielded themselves from the incoming shockwave, their hearts filled with shock. After an attack like that, would there even be any remains of Aldebaran left to find?
"What a waste. I wonder if Aldebaran had any useful materials on it? If it did, they've probably been vaporized by now," Sora said with a look of regret, staring at the center of the explosion.
After this, there probably wouldn't even be ashes left. It was truly a pity, a massive pity!
Hearing Sora's words, the people around her didn't know whether to laugh or cry. Who else would be thinking about materials at a time like this? Besides, if any material remained after a blast like that, it would have to be the best of the best.
Floating in the air, Ren Isana put away his staff after the spell concluded. Firing that [Piercing Magic Cannon] had left him feeling refreshed. The power was certainly sufficient, and he felt he could have pushed the output even further.
The upper limit of the [Piercing Magic Cannon]'s power depended entirely on the user's Magic Power, and Magic Power was the one thing Ren Isana had in abundance. He could have made it even stronger, though he chose not to.
As the explosion subsided, a massive crater was revealed before Ren Isana. The area where Aldebaran had stood was now a pit dozens of meters deep and over a hundred meters wide.
The entire hole looked as if it had been formed by a meteorite impact. Ren Isana scanned the crater and noticed something lying at the very bottom.
At that thought, Ren Isana decisively flew down from the sky and landed in the pit. In the center of the crater, a long rib bone had appeared. Seeing it, Ren Isana's eyes lit up.
"The restorative ability is actually this strong? A material that comes with its own auto-repair function—what a find!" This spinal bone had completely inherited Aldebaran's terrifying regenerative power.
There were many scorch marks on it from the high temperature, but it was already starting to slowly repair itself. One could only imagine how terrifying its recovery rate truly was.
Ren Isana didn't hesitate; he walked up and collected the rib bone. It was an excellent material. With a bit of processing, he could craft a weapon that repaired itself automatically.
And this was only from a Tier 4 Aldebaran. What about a Tier 5 Gastrea? What kind of existence would that be? At that moment, Ren Isana felt a surge of excitement. There were still several Tier 5 Gastrea left in the world.
Those were the true natural disasters. If he vaporized them all, what would they leave behind? Ren Isana fell into deep thought until Sora's voice drifted down from the top of the crater.
"Class Rep!" Sora and the others had appeared at the edge of the deep pit. Hearing the call, Ren Isana snapped back to reality. He would go after those Tier 5 Gastrea once this was over.
After all, there were only so many in the world. If he didn't deal with them, someone else eventually would. Since he and his group were here first, they might as well take all the benefits for themselves.
This was everyone's "First Clear" reward bundle. With that in mind, Ren Isana had a plan for their next moves: they would begin a worldwide hunt for all Gastrea Tier 4 and above!
