The magnetic field rotation that began in Jujutsu Kaisen

The essence of bioelectricity is ion flow.

Sodium ions, potassium ions, calcium ions, chloride ions—the movement of these charged particles inside and outside the cell membrane creates an electric current.

Muscle contraction requires the release of calcium ions.

Nerve conduction requires sodium-potassium ion exchange.

The heart needs pacemaker cells to automatically depolarize to keep the heart beating.

Every human movement and every thought is accompanied by the flow of bioelectricity.

What Dongyangping is doing now is transforming this instinctive, disorderly flow into an active and controllable "recharging".

Sweat seeped from the skin and was immediately evaporated into wisps of white vapor.

It wasn't because he was hot, but because the ions carried out by his sweat formed a weak ionosphere in the air.

Tiny flashes of light began to appear on his skin.

It wasn't the golden glow of a spell, but a pale blue, static-like faint light.

Crackling sound.

A very soft, crisp sound.

A tiny arc of electricity appeared at his fingertips.

The blue color, extremely pale, as fine as a strand of hair, danced briefly on his fingertip before disappearing.

But Dong Yangping saw it, and he smiled.

"It's done."

Dong Yangping began to try to guide these energies.

It's not about fighting, it's about "perception".

Allow bioelectricity to circulate in the body like blood.

To his surprise, it was much easier than he had imagined—because his body was already generating bioelectricity, only previously it was unconscious and disordered.

Now, he's just giving them a direction.

The nervous system is a natural conductor.

Nerve fibers are covered by a myelin sheath, much like the insulation layer on an electrical wire.

Action potentials are conducted in a skipping manner along the nodes of Ranvier, much faster than in unmyelinated nerves.

Dong Yangping directs his bioelectricity along the main nerve trunks—starting from the spine, passing through the brachial plexus to the arms, through the lumbosacral plexus to the legs, and through the vagus nerve to the internal organs.

For the first time, he could "perceive" his nervous system so clearly.

That wasn't a hallucination; it was a real perception—when bioelectricity flows through nerves, it generates a weak magnetic field, which can be perceived by a highly sensitive body.

According to Maxwell's equations, a changing electric field will produce a magnetic field.

Although the bioelectricity of the human body is weak, it does generate extremely weak magnetic fields—magnetic imaging and magnetoencephalography are based on this principle.

When the bioelectric intensity is high enough, the magnetic field will also be enhanced.

When a biomagnetic field is strong enough, it will have a unique characteristic—it will be particularly eye-catching.

Out of instinct, Tsukumo Yuki looked in the direction of Higashi Yangping and instantly noticed Higashi Yangping standing in the center of the courtyard!

At this moment, Dong Yangping had no time to pay attention to anything else; inspiration is always fleeting.

If we don't seize this opportunity and make a breakthrough this time, who knows when the next chance will come!

The faint blue glow on Dong Yangping's body is the corona discharge caused by the ionization of air. And those crackling sounds are the sounds of air being broken down.

The air in the courtyard began to feel eerie.

The raindrops that fell suddenly changed their trajectory the moment they approached Dong Yangping's body.

It wasn't repelled by any force, but rather attracted by an electric field—charged raindrops deflect in an electric field.

Dong Yangping raised his right hand, looking at the blue arc of electricity dancing on his fingertips.

It's very faint, thinner than a hair.

But he could sense the power contained within it.

It's not just electricity, it's also heat—when air is ionized, it generates high temperatures, even in a tiny area, the temperature can instantly reach thousands of degrees.

When the electric field strength is strong enough, air molecules are ionized, forming plasma. This process releases energy, and the temperature can reach 3000-20000 degrees Celsius.

Lightning has a temperature on this scale, several times the surface temperature of the sun.

Of course, the faint electrical charge on Dongyang Ping's fingertips wasn't that hot.

But the principle is the same.

As long as the strength is sufficient...

He clenched his fist, concentrating all the bioelectricity he could muster into his right fist.

No reservations were made.

This was his first time trying his best, and he didn't know what the consequences would be.

But he wanted to know.

I want to know where my limits are.

I want to know how far this road can take me.

On his fist, blue arcs of electricity began to thicken.

From the thickness of a hair, to the thickness of a chopstick, to the thickness of a finger.

The crackling sounds grew louder and more frequent, eventually merging into a piercing buzzing sound.

The surrounding air began to distort—not the kind of distortion caused by a heat wave, but a change in the air's refractive index caused by an electric field.

In Dongyangping, you can smell ozone. It's produced when the air is ionized.

There was also a burnt smell – that was from the skin on the surface of his fist, which was beginning to char under the high temperature.

But he doesn't care.

This pain was nothing to him, not even a disturbance.

"Open it!"

He threw a punch.

There was no destination in mind; I was simply facing the direction of the courtyard wall.

The instant the fist was thrown, a blue arc of electricity shot out from the fist, leaving a twisted trajectory in the air—

Then it hit the courtyard wall.

No, it wasn't "hit".

It means "through".

The electric arc seemed to be alive, instantly penetrating the interior of the brick wall.

The next second—

"boom!!!"

The courtyard wall was blown up.

It wasn't smashed apart by a punch, but exploded from the inside.

Bricks flew everywhere, and cement fragments shot out in all directions like bullets.

Dong Yangping stared blankly at the large hole, which was more than a meter in diameter, and then looked at his fist.

His punch didn't even hit the wall.

There are still at least two meters to go.

Was it that electric arc... that blasted the wall open?

No, it's not just electric arcs.

Because of the abnormally active electrical charge on his body, his brain was working at an extremely fast speed, and the knowledge deep in his memory instantly surged forth.

—When high voltage electricity passes through a non-conductor, it generates Joule heat.

Although brick walls are not good conductors, they contain moisture, and water conducts electricity.

An electric arc instantly heats water, causing it to vaporize and expand, generating enormous internal pressure—like a steam explosion.

When the internal pressure exceeds the brick wall's bearing capacity, it will burst open from the inside.

That's why the wall wasn't "smashed down," but rather "blown open."

The principle is the same as when an egg explodes when heated in a microwave oven—the internal pressure becomes too high, and the outer shell cannot withstand it.

Dong Yangping stared at the large hole, his eyes gleaming.

This was just his initial attempt.

What if he could control it more precisely?

What if he could make the current more concentrated?

What if he could increase the voltage and current?

A lightning bolt can instantly reach a temperature of 30,000 degrees Celsius, five times the surface temperature of the sun.

Although he doesn't reach that level, but—

One day, he'll be able to create an effect similar to Black Flash!

Dong Yangping suddenly realized that if this were a world with superpowers, he would have awakened lightning powers by now.

Clearly, this is the world of Jujutsu Kaisen, where superpowers don't exist.

This is a special state, a bioelectrical state!

Dong Yangping knew very well that it was impossible to maintain this state for a long time.

However, when this state is activated, the speed of nerve reaction, various bodily functions and physical strength all reach an unprecedented peak!

I'm going to take on ten!

Dongyang Ping is extremely excited!

"Feed, feed, feed—"

A familiar voice came from next door.

Yuki rushed out of her new home and stood in the yard, staring dumbfounded at the large hole that ran through the walls of the two houses.

She was still wearing that loose T-shirt, her hair was a little messy, and she was even clutching a notebook in her hand—obviously she was writing something down, when she was startled out by the explosion.

But her gaze did not fall on the hole.

She was looking at Dongyang Ping.

More precisely, she was looking at the still-flickering blue arcs of electricity on Dong Yangping's body.

"You you you you you—"

Tsukumo Yuki pointed at Higashi Yangping, her voice trembling: "What's that on your body?!"
