Japanese Terrorist: What? I'll fight Hellstar!

After completing all the formalities and paying the tuition with Tomie's wallet, Amamiya Rin changed into her indigo dojo uniform and returned to the dojo.

Sato Shisen was already kneeling at the front of the dojo, with a wooden sword in front of him, gesturing for Amamiya Rin to sit down opposite him.

"Modern Kendo originated from ancient styles, but has evolved into a competition primarily focused on athleticism and aesthetics. Yagyu Shinkage-ryu, however, is a sword that kills, but also a sword that brings life. Every move of its origins from the battlefield, solely for subduing, injuring, and killing the enemy. Its ultimate essence lies in drawing without a blade, in control and non-killing, that is, being able to kill but not killing."

Sato Shifan paused slightly, his gaze sharp as he looked at Amamiya Rin.

"Your swordsmanship is ruthless and direct, with traces of ancient styles. But your power generation, footwork, and mental techniques still follow the framework of modern swordsmanship... even a bit of an unorthodox approach."

Sato didn't know what to say.

In his view, the girl's swordsmanship was standard modern swordsmanship, but it was too fierce. The connection of her moves had deviated from the proper modern swordsmanship and was closer to ancient swordsmanship.

"We start with the Eight Postures. The so-called Eight Postures are the eight stances and mental techniques of our Yagyu Shinkage-ryu school. They are the foundation of the foundation, emphasizing tactics that adapt to the situation, and the harmony and variation of mind, breath, and body. Mind is spirit, breath is breathing, and body is technique."

Sato Shisen picked up the bamboo sword and stood up, and Amamiya Rin also stood up.

"The momentum moves with the positions of friend and foe, and arises with every breath. The Blue Eye Formation, with the blade tip pointing towards the opponent's eyes, is both oppression and a test. Breathe deeply; inhale to gather momentum, and exhale to press your energy through the blade tip..."

Amamiya Rin made the adjustments as instructed.

The Yagyu Shinkage-ryu school also has a secret breathing method, the effects of which are completely different from the Rokumyōmon breathing method. It focuses on the changes in breath and momentum, as well as the coordination with body posture.

However, although the effects were different, with the foundation of the Six Wonders, Amamiya Rin quickly learned the trick of the first posture.

Next came the middle stance, lower stance, rib stance, and kasumi stance... Master Sato explained the weight distribution, gaze placement, breathing coordination, and corresponding tactical intentions of each stance clearly and thoroughly.

Amamiya Rin learned extremely quickly. His twenty years of swordsmanship foundation in the dream world and the body control brought by meditation allowed Amamiya Rin to truly master it both mentally and physically.

The neural circuits in the brain's motor cortex are already activated in the dream; as long as the mind is focused, the signal will be transmitted to the corresponding location.

Sato Shisen watched from the side, his surprise growing stronger.

He would occasionally speak up to correct some minor details, and Amamiya Rin would always adjust them immediately.

In just half an hour, Amamiya Rin had grasped most of the form and essence of the eight stances. All she needed to do next was practice more, and with practice, she would master them completely.

"incredible……"

A young disciple observing from a distance murmured to himself, while his classmates were speechless, wondering if they were hallucinating.

"It took me almost a month to learn these eight postures and even get them to look decent..."

After Amamiya Rin demonstrated all eight basic stances, Sato Shisen remained silent for a moment, his eyes filled with complex emotions, before slowly speaking.

"...Very good. You remember very quickly."

He had taught swordsmanship for so many years, and he had never seen such an incredible learning ability.

It's not just about resemblance in form, but about capturing the essence of every posture in a very short time.

"It seems my previous assessment was too conservative. Your modern kendo skills are at least 20 years of experience. If it weren't for your poor physical condition, you could already be taking the kendo 7th dan certificate exam... Geniuses are always so unreasonable."

After saying that, Sato Shifu sighed deeply, a sorrowful expression appearing on his face.

"Master Sato, please teach me the techniques of the Yagyu Shinkage-ryu school directly."

Amamiya Rin didn't have much time to care about Sato Shisen's feelings. His lifespan was limited, and every minute and every second had to be used meaningfully.

"Don't aim too high. You've only learned the eight stances, not mastered them. As the saying goes, if the foundation is not solid, the earth will shake. Ancient swordsmanship is not child's play; every detail is crucial."

Sato Shifu frowned and said unhappily.

Faced with Sato Shisen's attitude, Amamiya Rin chose the simplest solution.

"Please, Master, I want to see the real Koken-ryu swordsmanship."

Tomie Kawakami's eyelashes trembled slightly, and her expression, which had been somewhat indifferent due to deep meditation, became lively. Her calm and composed tone softened, and her coquettish manner made Sato Shisen's breathing become erratic.

The other disciples in the dojo were also drawn to her. Looking at Kawakami Tomie's delicate figure, they couldn't help but hold their breath, a look of infatuation flashing in their eyes.

Although the new trainee had always been beautiful, her previous indifferent and dull expression changed, and her charm increased tenfold! Her coquettish voice was like Cupid's arrow, piercing their hearts.

Teacher Sato coughed lightly and glared fiercely at the students, who quickly looked away and pretended to continue practicing.

Then, Sato Shihan silently walked to the center of the dojo and picked up the bamboo sword again.

"Since you insist... then let's start with the Three Circles of the Great Sword. These are the three basic forms for dealing with high-level slashes, embodying the Three Principles of our school, and forming the basis for all subsequent techniques."

Sato Shifu's voice returned to its usual calmness, but he spoke a little faster than usual, and his gaze was shifty.

"Inoue, come here."

Sato Shifan glanced at his disciples, and a sturdy male disciple immediately jogged forward and bowed respectfully.

"You'll play the offensive role, use the uppercut slash."

Sato gave the instructions to Inoue, and then gave them to Amamiya Rin.

"Watch closely, this is the first move of the Three Arts of the Great Sword: Cut in Two with One Slash."

Inoue gripped his bamboo sword tightly with both hands, slowly raising it above his head, assuming a high stance. Sato, on the other hand, adopted the blue-eye stance, the tip of his sword slightly pointing towards Inoue's face.

"To complete your entry and attack outside the opponent's attack range. Ha!"

Sato Shifan gave a low shout.

Almost the instant Inoue's shoulder muscles tensed and he was about to strike down, his left foot had already stepped out. He shot forward like an arrow, and the tip of his bamboo sword drew a straight arc in the air, stopping precisely in front of Inoue's Adam's apple.

But Inoue's knife hadn't even had a chance to fall.

"This is the first of the first."

Sato Shifu sheathed his sword and said in a deep voice.

"Strike at the heart of the enemy with greater determination and speed before they make their move. The key is judging distance and timing, and avoiding head-on confrontation."

Amamiya Rin watched intently, and under the meditative observation, the depth of Sato Shisen's footsteps, the instant of his waist and abdomen exerting force, and the trajectory of his relentless thrust were imprinted into his brain like a brand.

The sunlight outside the temple window gradually slanted, its color changing from bright white to warm golden yellow, and the plaque "Sword and Zen as One" hanging on the wall cast a long shadow in the slanting sunlight.

The other disciples had finished their practice and were starting to pack up their equipment, but their eyes still kept glancing at the focused girl in the center of the dojo.

Kawakami Tomie, or rather, the will of Amamiya Rin who governs Kawakami Tomie, shows no sign of ending after three hours of training.

On the one hand, time was of the essence, and he needed to strengthen his abilities; on the other hand, having finally regained a healthy body, how could he bear to rest?

Anyway, since there's the Six Wonders Breathing Method that can reduce energy consumption and increase endurance, he plans to study it until after 10 p.m.
