At the moment when this inexplicable frequency vibrated, Pietro's body seemed to enter an illusory state.
A terrifying aura spread from him inexplicably.
Whether it was Natasha, Wanda, or Thor, all the gods' eyes focused on Pietro. Feeling the dangerous aura, their pupils suddenly shrank.
"What is this?"
Such a question flashed through the minds of Thor and the gods.
What had Pietro done to make them feel such pressure? They even felt that if they faced him directly, there would be only one outcome—death.
Under everyone's gaze, Pietro's expression twisted slightly in pain, but he still held his cross sword resolutely and rushed toward Surtur's head.
He completely ignored the frozen ice coffin.
In an instant, Pietro pierced through the ice coffin with his sword—and through Surtur's head as well.
His figure moved from the right side of Surtur's head and rushed to the left.
All of this happened in just a moment.
Time seemed to freeze.
In the distance, the noise of war roared, explosions thundered, and chaos reigned. But here, in this moment, everything was silent.
Wanda frowned. Her thin eyebrows knitted together, red light exploded, and in the blink of an eye, she disappeared from the sky.
The next moment, she appeared beside Pietro, looking at him with concern.
"Are you okay?"
"Not too good~~"
Pietro looked at his twin sister. His handsome face had gone slightly pale, and even his breath had become weak.
Wanda glanced at the behemoth beside them. At this moment, Surtur didn't move at all. He seemed... dead.
How did Pietro do that?
Could it be...?
Wanda instantly thought of something.
Sure enough, Pietro's next words confirmed her suspicion.
"It's resonance. This is what Boss Leon once suggested to me. I can use my super speed to vibrate my body and cell molecules. This allows me to phase through solid matter for a short time."
"So... after entering the resonance state, you phased through Surtur's head, materialized inside him, cut through his brain with your sword, and then phased again?"
Wanda's voice grew cold.
"That kind of technique requires extreme computational power. If you make even the slightest mistake, you could die because your body wouldn't be able to handle the shift between solidification and intangibility."
Her eyes flared with anger.
"You're insane."
She hadn't expected Pietro to take such a risk.
She wouldn't blame Leon for teaching him such a dangerous technique, but she was furious that Pietro had actually used it in such an uncertain situation. Taking such a risk...
This completely went against the principles of the Leon family.
Unless faced with a true life-or-death crisis, everything must prioritize survival.
Was this battle really that desperate?
Surtur was strong, yes. But this wasn't an absolute life-or-death situation.
Yet Pietro still chose, in Wanda's eyes, the stupidest possible way.
She simply couldn't imagine the horror of watching her twin brother die. That was unacceptable.
Pietro understood her anger, so he simply rubbed his head, smiled sheepishly, and let Wanda scold him without complaint.
"Hehe, it was risky, yeah, but I succeeded. And now that I have the experience, I'll soon be able to master this technique completely."
After venting her anger, Wanda frowned, while Pietro thought triumphantly.
Molecular phasing—a concept Leon had proposed long ago.
By using super speed and achieving absolute control over his body, Pietro could make his cell structure vibrate and resonate at the same frequency as a solid object, allowing him to phase through it.
This ability wasn't just powerful—it was game-changing.
With this technique, Pietro could shift between reality and intangibility, making him virtually untouchable.
Once he entered a resonance state, almost no attack—physical or energy-based—could harm him. It granted him an innate form of invincibility.
And in terms of offense?
He could bypass external defenses entirely and directly attack internal structures.
It was comparable to advanced internal destruction techniques—similar to Overlord Haki's high-level application.
With Pietro's speed on top of that? His strength had increased by several levels in one go.
He had now become an absolute killer.
And the proof lay in Surtur himself.
Surtur—the ruler of the Kingdom of Fire. A Heavenly Father-level being who had once fought Odin.
His demonic body was so durable that even Thor, Natasha, Wanda, and a team of sub-Heavenly Father-level powerhouses had been unable to break through his defenses despite their relentless attacks.
Yet Pietro...
Pietro alone had managed to cut through the inside of Surtur's brain.
That alone spoke volumes about how terrifying this technique was.
Real damage. Super assassin.
Just thinking about it made Pietro feel a surge of pride.
But Wanda...
Wanda glanced at her smug twin brother in disgust.
If she could, she would have slapped him awake right then and there.
She definitely needed to keep a closer eye on him in the future.
And when they got home...
Leon was getting a lesson of his own.
Teaching powerful techniques was one thing. Not warning Pietro about their dangers? That was the problem.
But just as the twins were talking—
In the distance, Thor and the gods stood frozen, staring at the motionless Surtur lying in the ice coffin.
They didn't know exactly what Pietro had done... but the result was clear.
Still—
It wasn't time for the gods to relax just yet.
Back near the ice coffin, the expressions of Wanda, Pietro, Natasha, and the others suddenly changed.
Their advanced precognition abilities kicked in—
And they saw what was about to happen.
Pietro reacted first.
He grabbed Wanda and vanished.
In the sky, Natasha and the others blasted away in an instant, their movements shattering the air as they shot into the distance like meteors.
Thor and the gods had no idea what was happening—
Until a second later, when their pupils shrank in horror.
Surtur, who had seemed lifeless just moments ago, suddenly began to glow.
A dazzling crimson light erupted from the ice coffin.
