A Scientific Urban Detective

"Nitrogen Armor," as the name suggests, is a layer of "armor" that can cover the entire body, rather than just a shield that can defend the front of the body.

Moreover, during the "Dark May Project," Kinuhata Saiai was implanted with Accelerator's mindset in terms of "defense," to the point that she is "naturally" more skilled at defense.

A mere high-pressure gas explosion is not enough to pose a substantial threat to her.

She sensed the damage to her "Nitrogen Armor" and immediately repaired it to ensure the "armor" was ready for use at any time.

Kinuhata Saiai felt even more confident and chased after the enemy without restraint.

Compared to Kinuhata Saiai's growing confidence, Metokouba was a little panicked. The "trump card" she had placed her hopes on had been taken head-on by the opponent, and without even getting hurt.

This gave Metokouba a feeling of being at her wit's end—even her explosions were ineffective against the target, so what kind of attack could break through her defense?

"Who exactly are you!" Metokouba couldn't help but ask, "What is this ability of yours!"

"Nitrogen manipulation," Kinuhata Saiai answered truthfully, not worried about any problems that might arise from revealing her ability information. "Surrender obediently, or else…"

Before she could finish her words, she saw Metokouba smile: "Nitrogen? As expected, no wonder the air pressure around you is abnormal."

With that said, a violent burst of air suddenly erupted in front of Metokouba.

Kinuhata Saiai subconsciously prepared to resist the impact—with the protection of "Nitrogen Armor," she wouldn't be injured, but the objective reality of her weight was there; if she didn't take certain measures, she could easily be blown away by a slightly stronger wind.

But unexpectedly, Kinuhata Saiai discovered that the "wind" was not blowing towards her head-on, but was attacking from behind her, as if someone had pushed her hard in the back.

Metokouba was rapidly compressing air, creating a localized vacuum!

—She was trying to seize control of "nitrogen."

Kinuhata Saiai immediately understood.

So she took advantage of the momentum and charged forward, as if swept up by a strong wind, and plunged into the enemy's embrace.

A fist enhanced with "Nitrogen Armor" smashed towards the opponent.

Bang!

Metokouba released the air she had just compressed, deflecting Kinuhata Saiai's attack, and then took advantage of her unsteady footing to slap down with her palm.

—As expected, a defense made of gas?

The palm strike was blocked by an invisible barrier. Metokouba snorted coldly and released the "high-pressure vessel" hidden in her palm.

The high-pressure airflow was like a sharp arrow, piercing into this barrier…

Kinuhata Saiai seemed not to notice the attack coming at her head and continued to concentrate on attacking the enemy with her other hand.

Bang bang, with two sounds of air exploding, the two were literally blown apart by the air, separated by a distance of about three meters.

Kinuhata Saiai's fist was once again deflected by the compressed air, and Metokouba's high-pressure airflow failed to completely break through the defense of the "Nitrogen Armor."

"Too inexperienced. Newcomers still need to strengthen their training," Mugino Shizuri commented from the sidelines.

Although both combatants were Level 4, Kinuhata Saiai's ability was undoubtedly more advantageous. Her "Nitrogen Armor" could be described as absolute defense below Level 4, naturally placing her in an invincible position.

Although Metokouba's attacks were powerful and fierce, they didn't seem to pose a substantial threat to Kinuhata Saiai.

In this situation, the fact that the two fought to a draw was, in Mugino Shizuri's view, something that shouldn't have happened. It was purely due to a lack of combat experience.

"Frenda, teach her some combat skills later when you have time," Mugino Shizuri said.

"Okay!"

The "Item" members were not worried about the outcome of the battle at all and didn't even intend to intervene.

Just like the analysis earlier, even if Kinuhata Saiai, who possessed defensive abilities, couldn't win, at least she wouldn't lose too badly.

"So troublesome…" Kinuhata Saiai muttered to herself. The enemy's attacks were far more troublesome than she had imagined.

Since advancing to Level 4, this was the second superpower that had made Kinuhata Saiai feel a fatal crisis.

By the way, the previous one was Mugino Shizuri's "Meltdown," which was indeed a terrifying attack that easily tore through the "Nitrogen Armor."

As for Komaba Toshimi, they had only probed and sparred a little before, so she didn't feel any danger.

But if the Metokouba in front of her became serious and concentrated all her strength to attack, she could probably break through the "Nitrogen Armor."

—My defense is no longer so "invincible," so I must be more careful.

On Metokouba's side, she was purely annoyed. In the previous battle, she had been stabbed in the shoulder by Komaba Toshimi's rapier, making it difficult to move one of her arms; at this time, she also had to deal with another powerful enemy, which was really a headache.

The most ⊥ new ⊥ small ⊥ said ⊥ is ⊥ in ⊥ six ⊥ 9 ⊥⊥ book ⊥⊥ bar ⊥⊥ first ⊥ hair!

"Tch, I've never encountered a superpower user with such a turtle shell in the underground arena…" Metokouba muttered.

After a series of exchanges, she could also judge that the key focus of the opponent's "nitrogen manipulation" was not on "gas," but on the "nitrogen element."

Although the two were almost synonymous in daily life, there was a significant difference in the superpower system.

—Simply depriving nitrogen is useless. This is not a closed space, and it is difficult to completely isolate the replenishment of external nitrogen.

"So…" A hint of ruthlessness flashed in Metokouba's eyes, "I'll use the strongest attack to break her shell and kill her in one fell swoop!"

With a strange cry, Metokouba charged towards her opponent, and a phenomenon of air distortion was already apparent in her palm—a rather astonishing mass of compressed air was brewing.

Kinuhata Saiai's expression was solemn. Without dodging or evading, she also clenched her fist and met the attack head-on. The layer of "Nitrogen Armor" on the surface of her body was constantly solidifying and reinforcing, and vaguely, one could even see the approximate outline through the refraction of light.

With "air" as the carrier, the head-on confrontation between the strongest spear and the strongest shield was about to erupt!

When only the distance of two arms remained between the two, Kinuhata Saiai suddenly twisted her body and threw a piece of marble debris in her hand.

The target was aimed directly at the opponent's face!

At such a close distance, even without any practice, it wouldn't be too far off the mark.

Although Metokouba's superpower was powerful, her body was only at the level of a normal human. At such a close distance, being hit in the face by a stone would still cause some injury.

In other words, even an attack at the level of a street brawl, as long as it hit, could still cause effective damage.

Not everyone can set up a powerful defensive ability close to the body like "Nitrogen Armor."

It was precisely because she realized this that Kinuhata Saiai had just casually picked up a piece of broken paving stone.
