Enchanting Body Tempering Technique

Satoru had noticed it long ago.

These brats, seven or eight years old, were quite precocious.

But thinking about it carefully, he felt relieved.

Kids in kindergarten in his previous life would often declare "XX is my wife!"

How many times had he seen them egging each other on?

It's just that...

"These guys... Nono is old enough to be my daughter, she's barely qualified to be my sister!"

Satoru gritted his teeth, staring at Shikaku's retreating back. He really had to introduce this guy to a strict wife in the future...

Nono seemed completely unaware of the situation. The little girl was startled by the commotion, but they seemed to be welcoming her...

"Don't mind them... a bunch of guys who like to mess around."

Satoru could only comfort Nono with a wry smile. His teacher really knew how to find trouble for him.

He still had magic to research, how could he have so much time to tutor Nono...

"Classmate Satoru... from now on, it'll... it'll be troublesome for you. I learn things quickly, so it won't take up too much of your time!"

Nono's adorable little eyes were like a kitten's.

"No problem, leave it to me!"

Could anyone resist the gaze of a little kitten?

"I certainly can't..."

Satoru, a former cat lover, helplessly closed The Book of Medivh and took out his own class notebook to hand to Nono:

"Here are my notes. Take a look first, and feel free to ask me if you don't understand anything."

"Th... thank you!"

Nono took Satoru's notebook and eagerly opened it—

The page was filled with neat, beautiful handwriting. The knowledge points were clearly organized, with Satoru's own annotations, and even directions for further research.

"As expected of classmate Satoru, whom the teacher praised so highly. I've never seen this kind of knowledge analysis method before..."

Nono quickly became immersed in this unprecedented notebook.

Many of the knowledge analysis techniques Satoru used, the application methods he proposed, and their integration with history and legends opened a new door for Nono.

As a mage who studied knowledge, this was Satoru's strong suit.

Combined with his rigorous and rational thinking from his previous life as an engineer, and his scientific analysis methods, Satoru's notebook was sufficient to be used as advanced teaching material.

It's just that Satoru clearly had no intention of showing off.

The reason Choza, Shikaku, and Inoichi had so much time and energy to practice Taijutsu with Satoru was also related to Satoru sharing his notes with them, greatly accelerating their learning speed.

With the help of the notes, it wouldn't take Nono too long to catch up to the second-year students' progress.

Unexpectedly having a kitten-like junior classmate to look after, Satoru still didn't neglect his magic and Taijutsu training.

Before he knew it, another year had passed. Under Might Duy's guidance, Satoru's physical fitness and Taijutsu combat skills had far surpassed those of his peers.

And hard work paid off. Satoru had successfully developed a method to apply Enchanting Body Tempering Technique as an enchantment for others.

Although the effect was much weaker compared to applying it to himself, once he became stronger, he could replace the previous enchantments with more powerful body-tempering enchantments.

This Enchanting Body Tempering Technique primarily strengthened the internal body, making it more resilient. It didn't have any immediate visible effects on combat power, at most slightly improving his resistance to damage.

However, for Might Duy, who was cultivating the Eight Gates Formation, the significance was entirely different.

With this, regardless of whether Might Duy could survive in the future, was it possible for him to annihilate the entire Seven Ninja Swordsmen?

Moreover, Might Duy, with his extremely high physical toughness, was an excellent experimental... ahem, subject.

When Satoru found Might Duy training alone and told him about this achievement, Might Duy couldn't believe it.

"To think... such a secret technique exists!"

Might Duy understood perfectly what kind of help this Enchanting Body Tempering Technique would provide him if it had the effects Satoru described.

"For the sake of secrecy, this technique has not yet been tested on anyone... and there are differences compared to the version I cultivate myself."

Satoru frankly told Might Duy that this was his personal secret, but Might Duy was slightly taken aback before accepting it.

"Youth always has its little secrets!"

Might Duy's teeth flashed with golden light, and he laughed heartily, giving Satoru a thumbs-up:

"Brother Satoru, don't worry, no secret can be leaked from me, Might Duy!"

"To risk exposing a secret and share such a profound technique with me, a mere Genin, I am truly... truly..."

Tears streamed down Might Duy's face. He hugged Satoru, who was grimacing, and said emotionally:

"From now on, you are my brother!"

"I've never feared danger! Feel free to experiment!"

"..."

Satoru finally broke free from Might Duy's bear hug. He looked at Duy's now incredibly determined face and nodded seriously.

"Don't worry... even if it fails, it will just have no effect. It won't get any worse."

Performing a large-scale enchantment on a human scale, and without the boost of Azeroth's mana-rich magical materials, Satoru could only use Arcane Power in conjunction with a magic circle.

To Duy, the magic circle looked like a slightly stranger ninjutsu formula, more magnificent and mysterious than a ninjutsu formula.

Duy sat cross-legged on the ground. Satoru drew a magic circle around him with special ink imbued with abundant Arcane Power, summoned The Book of Medivh with a wave of his hand, and began to cast the spell.

Satoru unleashed mysterious incantations and complex hand gestures. The magnificent purple of Arcane Power lit up from the magic circle, growing brighter and brighter.

Duy, sitting cross-legged in the center of the magic circle, felt a strange yet familiar power slowly seeping into his muscles and bones.

It seemed different from Chakra, yet also related.

Satoru's eyes lit up with a bright purple glow, and a bright purple radiance emanated from his body—

This was a phenomenon caused by Arcane Power being used to its extreme.

To Duy, however, it just seemed like a special kind of Chakra.

Satoru uttered the last few mystical syllables rapidly. The magic circle flared brilliantly, engulfing Duy in the center...

"Enchanting Body Tempering Technique—Complete!"

"Crack!"

The magic circle shattered into scattering arcane fragments and slowly disappeared. Duy, in the center, slowly opened his eyes.

"This feeling... it's truly beyond imagination!"

Duy clenched his fist in shock. He had been sensing the changes in his body with his eyes closed. As a ninja specializing in Taijutsu, his control over his body surpassed that of most people.

Now, his physical strength was about ten percent greater than before!

What did this mean?

In just a few minutes, the increase in Duy's physical strength was equivalent to a year of his hard training!

And this was a comprehensive enhancement, including his bones!

Conventional training could build muscle, but bone strength was incredibly difficult to train!

"I feel... I'm at least fifty percent stronger than before!"

Standing up, Duy couldn't help but want to let out a long cry to the heavens to vent his excitement, but he held back.

"It's good that it worked."

Satoru took a breath. The enchantment magic circle had consumed a lot of his energy. This was the first time he had used such a distinctly Arcane magic in front of someone else.

"But my strength is still far from enough. I can only enhance this much for now."

Satoru felt a little regretful. His current understanding of The Book of Medivh was only a little over 20%. Not only in terms of Arcane knowledge, but even in activating this powerful artifact, he could only unleash this much power.

"It's already very strong!"

Duy took a few deep breaths, his expression serious, and clenched his fists.

"Eight Gates Formation, First Gate of Opening—Open!"

"Second Gate of Healing—Open!"

"Third Gate of Life—Open!"

"Fourth Gate of Pain—Open!"

"Fifth Gate of Closing—Open!"

Before Satoru's astonished gaze, Duy's entire body turned red, veins bulged on his forehead, and only the whites of his eyes were visible!

"He's opened up to the Fifth Gate!" Satoru thought admiringly. Duy had clearly held back a lot when demonstrating for the four of them earlier.

Just as Satoru thought this, Duy let out a fierce roar, "Sixth Gate of Joy—Open!"
