Naruto: I'm really not an evil scientist!

"boom!"

The iron railing, struck by the chakra scalpel, suddenly exploded into several pieces, the broken surfaces as smooth as a mirror.

Hanabi stared in shock at her hands. She could feel the chakra surging through her meridians, but she never expected it to unleash such power.

"This is just the beginning."

Hiruko released his grip, letting Hanabi stagger back two steps.

When you truly master the subtle manipulation of chakra, you can be like Toneri...

He suddenly stopped and changed his words, saying, "So that, like a real medical ninja, one can freely switch between saving lives and killing people."

Hanabi looked down at her trembling fingertips, where the tangible sensation of the chakra scalpel still lingered.

She suddenly understood why Hiruko always made her practice the most basic chakra control—it turned out that all those seemingly tedious training sessions were for this moment.

"Now."

Hiruko turned and walked towards the edge of the training field. "Let's begin the real special training."

"Remember, the ultimate form of the Chakra Scalpel..." He suddenly turned around, a purple light, characteristic of the Tenseigan, flashing in his eyes. "It's about making every inch of skin a deadly weapon."

"This is precisely the subtlety of advanced chakra usage."

With a flick of his finger, Hiruko sent a scalpel of chakra crackling with lightning cleaving a blue stone ten meters away in two, leaving charred arcs of electricity on the cut surface.

The essence of the Rasengan is the pinnacle of chakra transformation—compressing attribute-neutral chakra into a high-speed rotating sphere.

And when you can make every acupoint in your body create a Rasengan...

He suddenly grabbed Hanabi's wrist.

Guide her to feel the miniature spiracle that is gathering in her palm.

Imagine the destructive force of this rotation combined with the cutting properties of a chakra scalpel...

With a soft "hiss," Hanabi was horrified to discover that the Rasengan she had condensed at her fingertips had been cut in half by Hiruko using a chakra scalpel!

The Rasengan that was cut open did not explode. Instead, it revealed the chaotic flow of chakra inside, like a deconstructed machine, and blue sparks flew in the air.

"Did you see it clearly?"

Hiruko spread his five fingers, with a miniature Rasengan of different attributes floating at each fingertip.

"When the cutting trajectory of the chakra scalpel forms a specific angle with the rotation direction of the Rasengan..."

He suddenly brought his index and middle fingers together, and two wind-attribute Rasengans were sandwiched between them. As the chakra scalpel cut in, they were transformed into two spinning chakra short swords.

"This allows us to create this kind of controllable rotating sword energy."

Hanabi felt like her brain was about to overload.

She watched as Hiruko's tongue trembled slightly, and the lightning-attribute sword energy he shot out drew a spiral trajectory in the air, shredding the iron lantern three meters away into pieces.

Then he suddenly closed his eyes, and tiny chakra sword energies erupted from all 360 acupoints on his body, forming a constantly rotating sword curtain behind him—this was clearly a defensive technique that combined the Eight Trigrams Rotation with the Rasengan!

"But...but isn't the Rasengan supposed to be maintained in shape by hand?"

Hanabi recalled how Naruto always needed to use both hands to coordinate his training, and she couldn't imagine how he could create such a difficult ninjutsu using pressure points.

"This is the advantage of the Hyuga clan."

Hiruko suddenly ripped open Huahuo's collar, revealing two acupoints below her collarbone.

The Byakugan allows you to clearly perceive the flow of chakra in your meridians, while the Caged Bird Seal, though despicable, unexpectedly enhances the ability of acupoints to contain chakra.

"He placed his fingertip on the 'Yunmen' acupoint on Huahuo's face, and the girl immediately felt a burning pain coming from that acupoint."

"Now try to channel your chakra using the Gentle Fist method, but don't release it..."

Hanabi gritted her teeth and followed the instructions to compress her chakra into her acupoints.

Suddenly, she felt that acupoint vibrate violently like a lit powder keg. If Hiruko hadn't stabilized it with his chakra scalpel in time, the meridians in her entire arm would probably have been blown off.

"See, this is where the difficulty lies." Hiruko wiped the sweat from her forehead.

"The Rasengan requires chakra to maintain its shape outside the body, but we need to complete this process inside the body."

Just like...

He suddenly pulled a wire from his sleeve and wrapped it around his finger.

Twisting a steel wire into a spiral requires both hands, but now we'll do it with one hand.

Before he finished speaking, he twisted the wire into a tight spiral using only his thumb and forefinger.

Hanabi nodded as if she understood, but suddenly noticed that the wire Hiruko was using to demonstrate was shimmering with a pale blue chakra light—it was not an ordinary wire at all, but a special prop materialized from chakra!

"As for chakra nature transformation..." Hiruko opened his palm, and five Rasengan of different natures spun in his palm.

"Wind attribute increases cutting power, lightning attribute paralyzes nerves, fire attribute causes burns, water attribute slows healing, and earth attribute aggravates injuries. When these properties are combined with a chakra scalpel..."

Chapter 231 Neji Steals the Master's Skill

He suddenly fired five Rasengans at the five trees simultaneously. Amidst the explosions, the five trees were transformed into different states: charred, frozen, cracked, muddy, and petrified.

Neji's voice suddenly came from behind the ruins: "This kind of ninjutsu... has gone beyond the scope of the Hyuga Gentle Fist, hasn't it?"

He looked at the artificial mountain that had been cut into an art piece, with spiral cutting marks still remaining on it, clearly a product of combining Baguazhang and Rasengan.

"Do not."

Hiruko picked up a frosty leaf, "This is the ultimate form of Gentle Fist."

Traditional Gentle Fist uses pressure point techniques to block chakra, but this...

He suddenly unleashed seven sword energies of different attributes from his fingertips, drawing complex hexagrams in the air. "It is a quantum-level superposition of the explosive power of the Eight Gates, the rotational power of the Rasengan, and the cutting power of the chakra scalpel through a change in nature at the moment of attack."

Hanabi felt like the back of her eye was starting to burn.

She suddenly realized that what Hiruko was showing was not ninjutsu at all, but a violent aesthetic that pushed chakra science to its extreme.

When the rotation of the Rasengan meets the cutting of the chakra scalpel, when nature change meets the burst of acupoints, the resulting chemical reaction is far more complex than a simple addition.

"Then...where should I start training?" Hanabi's voice trembled slightly, but her eyes burned with a fervent fighting spirit.

She remembered how her older sister Hinata always used Gentle Fist gently, while she longed for a deadly technique that could kill with a single blow—like the beautiful yet terrifying sword energy that Hiruko was now displaying.

“Starting tomorrow, throw 10,000 punches every day.” Hiruko suddenly became serious. “Not with your fists, but with your fingertips.”

I want you to be able to use your little fingertip to perform the complete Bagua Sixty-Four Palms within three months.

He unleashed eight sword energies, carving a hexagram three inches deep into the training ground.

"We'll talk about the Rasengan when you can unleash Gentle Fist with any part of your body."

The setting sun cast long shadows of the two of them. Hanabi looked at the messy training ground and suddenly laughed.

She knew that from this day forward, she would embark on an unprecedented path—a bloody path of evolution that would perfectly blend the Hyuga Gentle Fist with scientific ninja tools.

And the end of this road may be the ability, like Hiruko, to shoot out terrifying sword energy with his tongue that can cleave mountains.

"Very good. If you can maintain this clarity and caution, you will walk a more stable path in the future."

Hiruko raised her hand and gently stroked Hanabi's hair, her fingertips slightly gathering chakra as she used the gentle touch of medical ninjutsu to comb through the fine downy hairs that stood up due to her excitement. "Chakra scalpels and medical knowledge may seem like aids, but they are actually indispensable foundations for controlling powerful forces."

He turned and walked toward the ruins of the artificial mountain that had been cut off by sword energy. With a light tap of his fingertip, pale blue chakra wrapped around the rubble like silk threads, slowly lifting it into the air.

As the chakra flowed, fine patterns appeared on the surface of the rubble—traces left by the chakra left when it was cut by the sword energy.

“Look at these marks.”

Hiruko's voice was deep and focused, "The power, angle, and direction of rotation of each sword aura correspond to the flow path of chakra in the acupoints."

Medical knowledge can help you understand which acupoints can withstand what kind of impact, and which meridians need to have buffer space reserved.

Upon closer inspection, Hua Huo discovered that the patterns on the gravel were strikingly similar to the meridian diagrams of the human body.

She suddenly remembered the "Acupuncture Atlas" that Biluhu had made her memorize. At the time, she thought those dry words and diagrams were useless, but now she understood their profound meaning.

"So... the chakra scalpel is not only a means of attack, but also a tool for understanding one's own body?" she asked tentatively.

"It's much more than that."

With a slight twitch of his fingertips, the gravel instantly shattered into even smaller particles, but the cross-section of each particle was as smooth as a mirror.

"When you can precisely control the depth of the cut with a chakra scalpel, you can create a state of feigned death in battle—for example, severing the enemy's pain nerves without damaging vital organs, or temporarily sealing your own pressure points to fake death."

He suddenly reached out and pinched Hanabi's shoulder. The girl felt a numbness on half of her body, which quickly subsided. "Like this, I just sealed your Jianjing acupoint, but only with 30% of my strength, to make sure there are no aftereffects."

Hanabi stretched her shoulders, her eyes filled with amazement.

She recalled the Hyuga clan's traditional pressure point techniques, which, while capable of blocking chakra flow, were far less precise and nuanced than Hiruko's.

"What about medical ninjutsu? What does it have to do with sword aura training?" she pressed, the contradictory image of Granny Tsunade shattering rocks with her superhuman strength punches, yet healing wounds with her palm techniques, flashing through her mind.

"Medical ninjutsu is the ultimate test of chakra control."

Hiruko took out a roll of bandage from his sleeve and slowly wrapped it around his fingertips. "To heal a wound, chakra must be allowed to permeate every inch of tissue like flowing water; and to release sword energy, chakra must be as sharp as a blade."

These two seemingly contradictory concepts actually share the same origin—both represent the ultimate control over the transformation of chakra forms.

He suddenly tightened the bandage, and a sword aura as thin as a hair shot out from his fingertip, slicing the leaves of a tree ten meters away in half, while the bandage itself remained intact. "Just like this, I can keep the chakra flowing gently on the surface of the bandage, but condense it into a sword the moment it is shot out."

Hanabi took the bandage and discovered that it still contained a faint trace of chakra.

She tried to imitate Hiruko's movements, but her chakra exploded out of control as soon as it gathered, startling her so much that she quickly took two steps back.

"Don't rush." ​​Hiruko chuckled, grasping her wrist and guiding the flow of chakra. "Remember, the core of medical ninjutsu is 'sensory perception'."

You must be able to sense the temperature, humidity, and flow rate of every strand of chakra, just like sensing a patient's pulse.

With his guidance, the fireworks gradually calmed down.

She closed her eyes and focused her mind on feeling the flow of chakra within her body.

Gradually, she seemed to "see" her meridians surging like rivers, and the acupoints like whirlpools in the rivers.

As the chakra flowed through the Yunmen acupoint, she followed Hiruko's instructions and gently manipulated the vortex with her mind—in an instant, a sharp wisp of chakra shot out from her fingertip, leaving a shallow mark on the ground.

"I did it!" Hanabi opened her eyes and looked excitedly at her fingers.

Although the marks were shallow, this was the first time she had actively released chakra that resembled sword energy.

"This is just the beginning."
