A Scientific Urban Detective.

Chapter 638: Unable to Save Those Who Have Already Been Saved
After removing the silver needle and completing his own treatment, Oreos still had no intention of starting a fight. Instead, he turned around calmly, exposing his back to Stiyl and Kamijou Touma, made a "Follow me" gesture, and then strode forward.

Stiyl and Kamijou Touma looked at each other and hesitated for a moment. Although they were not sure of this guy's intentions, they finally chose to follow him.

Because they are on the "back" of the world, the spatial structure here is completely beyond the normal scope of Misawa Academy.

Even the experienced Stiyl didn't know where they were moving to. Oreos finally stopped at the door of an empty classroom.

Snapped!
He raised his hand and snapped his fingers, and suddenly a huge "amber" appeared in the empty classroom.

In this "amber" that is more than one meter tall, there is a girl wearing a shrine maiden's costume sealed - Himegami Aisa.

"What did you do to her!" Seeing this, Kamijou Touma roared angrily and was about to rush into the classroom.

"Please don't come near me." A disembodied female voice came from every corner of the classroom, stopping Kamijou Touma's actions. "I have seen your ability, Kamijou Touma, so please don't come near me."

“Huh?” Kamijou Touma stood there in a daze.

The girl in "amber" opened her eyes and looked at me with bright eyes.

This scene clearly exceeded Kamijou Touma's expectations... Although his brain couldn't comprehend it for a moment, he was somewhat aware of one thing - this girl didn't seem to be simply imprisoned.

"Just as you can see." Aureos said, snapping his fingers again.

The "amber" that sealed the girl expanded and soon filled the entire classroom.

As a result, Himegami Aisa was able to move freely within the classroom. Although the area of ​​activity was still limited, it was clearly different from the "imprisonment" that had been originally envisioned.

"What's going on? What do you want to say?" Steele finally couldn't help but ask.

"I'll come see you later." Oreos did not answer directly, but greeted Himegami Aisa and then closed the classroom.

Then he opened another classroom next door.

Repeat the same operation, and there is also a large "amber" in this empty classroom.

However, there is only "half a person" sealed in this "amber".

That’s right, “half a person”.

To describe it accurately, it is "the human body in the process of desertification."

The right half of the man's body, which was stretched forward, had turned into a pile of fine sand, floating in the air - it was in this process that it was sealed in the "amber".

At first glance, no one would think that this is a "person", but rather some kind of special effect or work of art.

Thanks to this "amber", the man was sealed inside in time and barely saved his life.

"This is..." Kamijou Touma swallowed his saliva. He learned from his previous lesson and did not rush to shout.

"Vampire." Oreos said, "This is the vampire, and this is the target I want to capture."

As he spoke, Aureos grew out his long nails again: "This is the result of my reference to this vampire gentleman."

Aureus had collaborated with the "vampire killer" Himegami Aisa, aiming to use her as bait to capture vampires. "Is this a vampire?" Stiyl looked at the half-human figure in the classroom with suspicion.

To be honest, I'm quite disappointed - because it looks too weak.

"What do you think vampires and 'blood-sucking killers' are?" Aureos scoffed. "Those born strong and invincible? Wrong!"

"That's what vampires are like," Oreos said, pointing at the remains in the classroom. "Aside from being killed instantly by vampire killers, they're practically no different from ordinary people."

"As for the vampire killer... her blood can both attract and kill vampires." Aureos's face was full of sarcasm. "She is a natural vampire trapper. As long as she stands there, vampires will rush towards her like moths to a flame and then turn into ashes... that's all."

So, vampires and blood-sucking killers are nothing big – Oreos concluded.

According to Oreos's explanation, the only reason he wanted to capture the legendary creature vampire for research was to "save Index."

Because according to legend, vampires have infinite lifespans and can live forever as long as they are not killed.

Infinite lifespan means infinite memory and information. How do creatures like vampires store and manage their memories?

Oreos was inspired by this - as long as Index was turned into a vampire, the shackles on her memory could be removed.

Even if there is only 15% of memory space left in the brain, as long as I become a vampire, there should be a way to use this space to store more content without having to delete memories regularly, right?

Oleios's plan went smoothly. He did capture a vampire and sealed him before he was killed by the "vampire killer", thus obtaining a research sample.

After hearing his explanation, Stiyl and Kamijou Touma both had complicated expressions.

Recalling the scene not long ago when Lin Wuming and Misaka Mikoto refuted the "memory storage theory", he inexplicably felt that the Oreos in front of him was as stupid as they were at the beginning.

No, it should be said that this guy is a little more stupid, because he did put his plan into action and actually achieved certain results!
"And then," Stiyl asked, "you chose to turn yourself into a vampire first?"

"Of course, we can't use Index as a test subject, right?" Oreos said. "Besides, becoming a vampire has indeed made up for my shortcomings to some extent. Just drinking a small amount of blood can calm me down, which is more effective than acupuncture."

What just happened has proved this.

Stiyl sighed in his heart - the "secret" that Lin Wuming told them was no longer effective.

It seems that Lin Wuming has not realized the fact that this guy has become a vampire?

"Well," Aureos turned and looked at the two of them, "Stiyl, do you think I can save Index now?"

"Of course not, idiot," Stiyl said bluntly.

"Hey, there's no need to be so blunt." Kamijou Touma felt a little reluctant.

"For an incorrigible fool, the only way to make him understand is to explain clearly enough," Stiyl said. "Listen carefully, Aureos, you are destined to fail in saving Index!"

"Oh, why?" Oreos' expression remained unchanged, as if he didn't notice the other party's ridicule.

Stiyl said with infinite sarcasm: "Because, no matter who it is, it is destined to be unable to save a person who has already been saved."
