The magnetic field rotation that began in Jujutsu Kaisen

The setting sun bathed this old residential area in Saitama Prefecture in a warm orange-red hue.

The courtyard gate.

Qi Haijian bowed politely, picked up his half-empty backpack, and walked towards the gate of the courtyard.

As he reached the door, he suddenly stopped and turned to look at Dong Yangping.

The boy's yellow-green eyes were exceptionally serene in the twilight.

"Mr. Dongyang."

"Hmm? Is there something you've forgotten?"

"no……"

"Your duel with Senior Tsukumo Yuki just now... I learned a lot from it!

"Thank you! This is a very interesting world around us!"

Dong Yangping paused for a moment, then chuckled, "That's really interesting! Remember to come visit often; you're always welcome. And don't forget, I've already registered you with my company!"

Qi Haijian's eyes gleamed: "Great!"

Dong Yangping watched that small figure slowly walk towards the end of the alley, and suddenly felt that something had changed—

"Tanaka," Higashiyohei called out.

Butler Tanaka strode in from outside the courtyard: "Young Master."

"Arrange a car to take Nanami-kun back. Get him there safely."

"clear."

Tanaka quickly chased after him.

The courtyard gradually quieted down.

Dong Yangping slowly stood in the middle of the tattered lawn, looking down at the scorch marks on his chest.

The traces left by the black flash.

The skin surface was a palm-sized patch of charred black, with fine cracks along the edges, resembling a dried-up riverbed.

It feels slightly warm to the touch, but there is no stinging sensation—it's a superficial wound, not even affecting the dermis.

But he did not treat the wound.

He just stood there, head down, staring at the charred area.

My fingers gently caressed the edges of the wound.

Again and again.

Tsukumo Yuki was still standing not far away, his expression complex.

She wanted to say something, but seeing Dong Yangping's absent-minded look, she swallowed her words.

She glanced at Dongyang Ping, then at Jiujiu Youji.

"He's fine." Shen Er said matter-of-factly, "He's just like that."

Yuki Kujukuri asked curiously, "What state?"

"What did you realize?"

Shen Er shoved the knife back into Chou Bao's mouth, which was perched on his shoulder: "He's often like this. After a fight, he inexplicably starts spacing out, probably thinking about what just happened, analyzing where each move and stance can be optimized or improved."

He paused, then added, "Sometimes I can space out for an entire night."

Tsukumo Yuki was stunned.

She looked at Dongyang Ping.

The man stood there in the twilight, motionless, like a statue.

But his fingers were still moving.

A very subtle movement—the index and middle fingers lightly traced the scorch marks on the chest, as if tracing some kind of path.

Then, he raised his right hand and drew a circle in the air.

Very slow, very gentle.

But the moment the circle was drawn, the air made a barely perceptible sound.

It was as if it had been stirred up by some force.

"..."

Ninety-nine yogi pupils constrict.

She saw it clearly just now—when Dongyang Ping drew the circle, there was no magic power or energy fluctuation.

It's purely physical movement.

But that circle perfectly cut into the gap in the airflow, forming an invisible "barrier".

Although the barrier only existed for a fraction of a second before disappearing, it was a real barrier that existed.

What is this? Martial arts?

But whatever it may be, Dongyangping's understanding of "force" has reached an unbelievable level.

"I'm leaving now," Yuki Tsukumo suddenly said, her voice somewhat hurried.

Shen Er glanced at her: "Not going to watch the show anymore?"

"He's fine." Tsukumo Yuki shook her head. "The fact that my black flash didn't hurt him means his physical strength far exceeds my expectations. I need to go back and reorganize the data and adjust my research direction."

She walked to the motorcycle parked outside the yard and climbed onto the seat.

The engine roared.

Before leaving, she turned back to take one last look at Dong Yangping.

The man remained standing there, head down, his fingers still unconsciously tracing lines in the air.

Dusk enveloped his silhouette.

Tsukumo Yuki put on the helmet, his eyes hardening.

"I will come again," she said softly.

With the throttle fully twisted, the motorcycle shot off like a black lightning bolt.

Shen Er stood in the courtyard, looking in the direction where Jiujiu Yuki had disappeared, and then looked at Dongyang Ping.

His voice was barely audible: "You'd better not come."

Then, Shen Er turned around and went into the house, picking up the old backpack.

"I went to the hospital."

Dong Yangping did not respond.

He didn't care at all and pushed the door open to leave.

The footsteps faded into the distance.

Dong Yangping was the only one left in the courtyard.

There was also twilight, the evening breeze, and the lawn covered in rubble.

By the time Tanaka returned after seeing Nanami Kento off, it was already completely dark.

He was startled to see Dong Yangping still standing in the same spot, in almost the exact same posture as he had been more than two hours earlier.

"Young Master?" Tanaka approached cautiously. "Would you... like something to eat?"

no respond.

Tanaka dared not disturb them any further, and quietly retreated to a corner of the yard, where he stood guard in the shadows.

The night breeze grew cool, and the moonlight was like water.

Dong Yangping still stood there, like a tree that had taken root.

His eyes were half-closed, and his breathing was long and slow—only three breaths per minute.

This is a physiological characteristic of him when he is in a state of extreme focus, where his metabolism is reduced to a minimum, maintaining only basic life activities.

The brain, however, is operating at overclock.

Black flash.

What happened in that instant?

Tsukumo Yuki's fist was imbued with cursed power, combined with pure physical attacks.

According to the theories of this world, black flashes must be triggered by cursed power—a phenomenon caused by the time error between the cursed power hitting the target and the space.

But the force of that punch was clearly very strong.

How could it break through space? Is it a problem with the cursed power? Is it a conflict between the cursed power and the physical body, or a conflict of forces?

Black Flash...

Essentially, it's about creating a visual residual effect by breaking the spatial boundaries.

The original setting states that the attack power bonus is 2.5 times...

So, the stronger the physical body, the stronger the attack power, or...?

unless……

So... is it possible to unleash a black flash using pure physical strength?

Theoretically, it should be possible to... break through space...

Dong Yangping drew another circle in the air with his finger.

This time, I drew very slowly.

He closed his eyes, focusing intently on feeling every change in resistance as his fingertips brushed against the air.

Air is a fluid.

Since it is a fluid, it has velocity, density, pressure, and shear force.

Given enough force and speed, it is possible to create "cavities" in a fluid—similar to the cavitation effect produced by a high-speed bullet in water.

Could the black flash be some kind of "cavitation" created in space when the power of the curse and the physical strength work together?

No, that's not right.

He shook his head.

The essence of Black Flash is the spatial distortion error caused by the combination of cursed power and physical impact.

Without magical power, there should be no black flash.

What if we use other forces instead of magical power to create this "cavitation" error...?

But what power should be used?

Dongyang Ping was immediately stumped; the conditions were insufficient, and he couldn't deduce the result.

Dong Yangping opened his eyes and looked down at his chest.

The scorch marks are still there.

He pressed it with his finger, feeling the tremors of the muscles beneath his skin.

Then he turned and went inside, picking up the glasses from the low table.

"The Mirror of Manifestation".

Dongyang Ping put it on.

A faint glow immediately appeared on the lenses. This was a sign that the magical power had been activated—the magical power stored in the glasses was now in operation.

He looked out the window.

There was nothing there.

He looked at his hands.

There was nothing there.

He looked out over the courtyard.

There was nothing there.

Cursed spirits, traces of cursed power, remnants of spells... all "existences" related to the world of curses are a blank in the field of vision of these glasses.

Just as I sensed, there was no magical power here.

Perhaps it once existed, but it has since disappeared.

Dong Yangping was lost in his memories again.

The instant Tsukumo Yuki's fist touched him, when the black flash struck him—

He sensed it.

It's not with your eyes, not with your ears, not even with your skin.

Instead, it uses some deeper, never-before-activated senses...
