A Scientific Urban Detective

"Tsk!" Looking at the results of her attack, Kinuhata Saiai reluctantly retracted her fist.

The last punch just now couldn't really be considered "Nitrogen Armor" anymore, but was closer to "Nitrogen Burst Lance"—concentrating the nitrogen blocks she manipulated to a single point as much as possible to generate maximum destructive power.

However, Kinuhata Saiai's ability was ultimately a "shield," and even at its most concentrated, it was still as thick as a bucket, far from being a "spear."

"As expected, a spear is much more useful for this kind of thing…" Kinuhata Saiai muttered, but her hands didn't slow down at all.

A hole only the size of a washbasin was impossible to pass through—they couldn't possibly expect the girls to squeeze through, could they?

But once there was a hole, they could further expand their gains.

With the enhancement of "Nitrogen Armor," Kinuhata Saiai's strength was greatly increased, and she directly tore open the door "barehanded" in a few moments.

"Alright, we can go in now!" After tearing open a passage large enough for an adult to pass through, Kinuhata Saiai finally stopped and patted the non-existent dust off her hands.

"As expected of a level 4, their abilities are so unreasonable," Frenda complained while launching a rocket she had been holding in her hand towards Kinuhata Saiai.

Kinuhata Saiai remained indifferent to the attack from behind, not even twitching an eyebrow, and instead erected "Nitrogen Armor" in front of her.

As expected, there were people inside the factory, or at least defense facilities.

A series of bullets shot towards the breach in the door like pouring water.

But none of them managed to penetrate the defense of "Nitrogen Armor."

With two whooshing sounds, Frenda's rockets streaked past Kinuhata Saiai's body and into the factory interior.

Accompanied by two small explosions, the density of the rain of bullets suddenly decreased.

Mugino Shizuri unceremoniously pushed Kinuhata Saiai aside and blasted an incredibly thick, emerald green beam of light into the factory.

"Meltdowner" was indestructible, and after the emerald green light faded, the resistance inside the factory completely subsided.

"Takitsubo?" Mugino Shizuri looked behind her.

Takitsubo Rikou shook her head: "I didn't detect any particularly powerful espers, only weak reactions below level 2, presumably test subjects."

"What about the others?"

"For ordinary people, the number is between forty and sixty," Takitsubo Rikou continued to shake her head, "Their AIM diffusion fields are even closer to zero, so I can't see very clearly."

Mugino Shizuri nodded: "In other words, besides a bunch of weak test subjects, the rest are just guys who can handle firearms?"

After confirming the enemy's strength, Mugino Shizuri flipped her hair: "Well, there's no difficulty, let's finish this quickly and go home."

With that, she took the lead and walked into the factory interior.

"Mugino, let me go first…" Kinuhata Saiai said quickly, remembering her team role as the shield at the front.

"Just protect Takitsubo," Mugino Shizuri said without looking back.

But there was indeed no need to worry. After the previous round of "Meltdowner" scans, the entire factory interior was a mess, reduced to a ghastly ruin, with not a trace of resistance.

"In the end, there were only automated defense robots here," Frenda found the two machine gun turrets she had destroyed—fully automatic, unmanned operation, essentially guard robots.

"The information says that the main part of the research institute is underground," Takitsubo Rikou looked at the ground beneath her feet, "All the fluctuations are coming from below."

Fortunately, the entrance to the underground was not destroyed by "Meltdowner," and the four of them easily reached the underground space.

They finally met the security personnel of this research institute, and then they were directly destroyed by "Meltdowner."

Only some body fragments were left on the ground, probably not enough to assemble a complete body even if several people were put together.

Kinuhata Saiai tightened her face, trying to quickly adapt to these tragic and even somewhat grotesque "corpses."

Imagining these corpses as those researchers from "Dark May," Kinuhata Saiai immediately felt much better.

Mugino Shizuri was also distracted, observing the newcomer's performance. She had deliberately made the scene so tragic—if she wanted to, "Meltdowner" could completely blow a person into ashes, or just leave a small wound on their body, leaving the enemy with some final dignity.

But Kinuhata Saiai didn't have any of the reactions of a rookie. Although she was a little uncomfortable at first, she quickly regained her composure and was even able to directly look at the corpses with ease—this couldn't be faked.

"Very good," Mugino Shizuri praised with a nod, then quickened her pace and repeated, "Speed up, let's finish this quickly!"

Frenda and Takitsubo Rikou also knew about Mugino Shizuri's "test" just now. They were also very pleased that Kinuhata Saiai was able to pass the final test and truly become a comrade.

Since the incidental matters were all done, Mugino Shizuri and Frenda went all out, sweeping through everything. It only took them more than twenty minutes to eliminate everyone in this research facility.

"It's gone." Takitsubo Rikou activated her ability again to confirm, "All 'people' have been eliminated."

"Well, that's it." Seeming like she had just warmed up and hadn't had time to start exercising properly, Mugino Shizuri was a little unsatisfied, "Let's go home… hmm? Where's that little brat Kinuhata Saiai?"

Noticing that the bodyguard was not next to Takitsubo Rikou, Mugino Shizuri raised her eyebrows, revealing an unpleasant expression.

"She's taking care of the test subjects," Takitsubo Rikou said, "She already told me just now that because the battle was over, she would go."

"You can't be so careless," Mugino Shizuri said with a frown, "What if there are still surviving enemies?"

"That won't happen," Takitsubo Rikou said with a smile, "My 'Ability Observation' won't make such a serious mistake."

In a room next door, Mugino Shizuri and the others found Kinuhata Saiai taking care of the test subject children.

Several rows of full-coverage medical pods were neatly arranged in the room.

For the sake of convenient management and cost savings, the test subjects here were uniformly stored in medical pods filled with nutrient solution.

Except when they were being experimented on, they would be forced to sleep at other times.

This situation was quite tragic, and even Kinuhata Saiai, who also came from an illegal research institution, couldn't stand it—you know, even "Dark May" didn't treat the test subjects like this. They weren't even "experimental animals," they were simply "experimental materials!"
