Super Hardcore Teacher

As Uchiha Fugaku revealed his Three Tomoe Sharingan, Hiashi Hyuga fearlessly opened his Byakugan to meet his gaze.

Their Hyuga Clan and the Uchiha Clan were ancient enemies. In the late Warring States period, they had even experienced a brutal war, with the Hyuga Clan nearly being crippled by Uchiha Madara and his Uchiha forces.

He had not forgotten this deep-seated blood feud!

Similarly, Uchiha Fugaku held no good feelings towards the Hyuga Clan.

"What a shame!"

He retracted his Sharingan and turned his gaze to Hiashi Hyuga, who wore the Konoha forehead protector. Uchiha Fugaku sighed regretfully.

He had been keeping a close eye on the leading figures of the Hyuga Clan in this generation. He understood clearly that in terms of talent and strength, Hiashi Hyuga, the younger brother, was stronger. Unfortunately, he was branded with the Caged Bird Seal, which not only caused a weakness in his Byakugan and damaged his potential but also significantly dampened his spirit.

This person was ruined. At best, he would become an Elite Jonin in the future, with no possibility of becoming a Quasi-Kage.

As for Hiashi Hyuga...

"Heh heh..."

Fugaku let out a cold, disdainful laugh and left with Mikoto Uchiha.

Hiashi Hyuga was indeed not bad, but at most, he would only reach Quasi-Kage Level. He would have no chance of becoming a True Kage Level expert. Fugaku didn't even bother to look at such a person.

The Hyuga Clan was destined to be trampled under the feet of the Uchiha!

Fugaku's disdainful cold laugh before leaving made Hiashi Hyuga's face turn ashen. The veins around his eyes throbbed incessantly due to the activation of his Byakugan.

All Uchiha deserved to die!

"What's with all the arrogance!"

Staring at Fugaku Uchiha's retreating back, Nawaki Senju grumbled discontentedly. Then, he looked at the Shimura clan member who had picked up the iron hook.

"Uncle, let me try too!"

After another moment of silence, the Shimura clan member handed the two-meter-long iron hook to Nawaki Senju.

Having specialized in Taijutsu for the past few years, Nawaki Senju's physical condition was not weak. Coupled with the enhancement of Chakra, he could drag the heavy outer shield, but that was all he could do.

It was absolutely impossible for him to lift it, let alone approach it due to the radiation from the Sealing Crystal.

Next, the elite class students from various grades also stepped forward to try, gaining a further understanding of Shimura Kentei's strength.

"Choza, when you were thirteen, could you have had strength like his?"

Shikaku Nara asked, squatting on the ground and looking at the heavy outer shield. This physical quality was truly astonishing.

"At thirteen, I probably wouldn't be worse than him, but I only have strength. In terms of flexibility and speed, I'm not as good as him. If I use the Expansion Jutsu, my strength can crush him."

Choza Akimichi replied, chewing on beef jerky. He indicated that by the time he was thirteen, he would also possess this kind of strength, and even more so after using the Expansion Jutsu.

It should be known that Choza Akimichi's uncle, Defū Akimichi, had a super-sized steel battle axe weighing tens of tons, specifically made for the Super Expansion Jutsu. In terms of physical strength alone, he was the best in the Ninja World.

Of course, this was only in terms of strength; his speed and agility were significantly inferior.

"How did he adapt to this thing?"

Shikaku Nara thought of another problem. He had just tried it himself. After getting within half a meter of it, the Chakra within his body began to go out of control. If he hadn't retreated in time, his Chakra would have surely gone berserk. That was no joke.

So the question was, how did that guy adapt to the radiation of this Sealing Crystal?

Others were also pondering this question. If it were just a set of armor and a shield, it wouldn't be much. It was said that the samurai from the Land of Iron often did such things.

But once it was combined with the Sealing Crystal, it became completely different, making them almost immune to ninjutsu.

Shimura Kentei, naturally, was unaware of everyone's thoughts. He was currently receiving treatment from Tsunade, with several physicians assisting him.

These physicians from the Konoha Hospital were responsible for the fractures in other parts of his body, while Tsunade focused on his shattered arm and damaged internal organs.

It had to be said that Tsunade, with the Senju Hashirama's Body, had a unique advantage in Medical Ninjutsu. With the assistance of powerful Yang Release Chakra, within an hour, the fractured bones of his shattered arms had initially healed. From then on, it would only take continuous nourishment for them to fully recover within a week without any problems.

"You little pervert, the hardness of these bones is very abnormal!"

Tsunade examined a piece of bone the size of a fingernail, even pinching it. She became even more curious about this cheap disciple.

The hardness of these bones was very abnormal. The calcium content within far exceeded that of ordinary people, and it was not inferior to that of Elite Jonin who had specialized in Taijutsu.

Most importantly, the density of these bones was very uniform. In fact, the bone density and strength throughout his entire body were almost identical. This was very abnormal.

Looking at the broken bone being subjected to all sorts of abuse by Tsunade, Shimura Kentei felt completely unwell.

That piece of broken bone was naturally his. He could have gathered it back, but this woman forcefully took it out for research.

Were the leading teachers this hardcore and brutal these days?

"That's the Bone Forging Secret Technique from the Body Strengthening Technique developed by our Shimura Clan. It can enhance bone density, thereby improving bone strength, toughness, and other characteristics."

"Body Strengthening Technique? You really do have a complete set of Body Strengthening Secret Techniques!"

Tsunade replied with an expression of "as expected." While treating Shimura Kentei's injuries earlier, she had conducted a detailed examination and found that all aspects of his body far exceeded those of ordinary people, and even his internal organ functions were very powerful.

However, his vitality was very ordinary. It was certain that he did not possess the Senju Clan's Hashirama's Body bloodline.

After all, the essence of the Senju Clan's Hashirama's Body was powerful vitality. With powerful vitality, one could cultivate strong physical qualities.

Thus, it seemed that this brat's possession of such physical qualities was not due to innate reasons but was achieved through hard work and cultivation.

This showed the power of the Shimura Clan's Body Strengthening Technique, which could almost mass-produce Taijutsu-specialized Chunin.

This has reached a strategic level and is of great significance.

Of course, although Tsunade was very interested in this Body Strengthening Technique, she didn't ask for it again.

The inheritance of secret techniques is the foundation of ninja clans. Even the Hokage has no right to seize others' secret techniques, so she naturally wouldn't violate this taboo.

Moreover, the Shimura Clan is not weak nowadays, and Danzō Shimura is the second-in-command of the village. He also advances and retreats with Hiruzen Sarutobi and others, so no one would dare to provoke them.

"Tsunade-sensei, I plan to use this opportunity to deepen my practice of the Body Strengthening Technique. Please cooperate with your Medical Ninjutsu."

Seeing that Tsunade held back from asking, Shimura Kentei thought highly of her and then stated his intention to practice the Body Strengthening Technique, further tempting her.

Although in the original work, Tsunade passed down her family's secret techniques like the Yin Seal and Monster Strength Technique to Sakura Haruno, the Senju Clan had already declined and even disappeared by then, so there was no need to worry about others.

But now, the Senju Clan is at its peak. Even if it's not as powerful as when Hashirama Senju and Tobirama Senju were alive, it is still extremely strong, arguably the number one clan in the Ninja World, even suppressing the Uchiha Clan.

Therefore, at this stage, if he wanted to learn the Senju Clan's secret techniques like Monster Strength Technique from Tsunade, he would need to use some means.

"This is not part of your mission to heal your injuries!"

Although she was tempted by this proposal, which would allow her to glimpse the secrets of the Shimura Clan's Body Strengthening Technique, she, Tsunade Hime, was a professional with integrity and never did anything outside her missions.

Unless she was paid more!

"Ten million Ryo!"

Shimura Kentei, who had long seen through the essence of this teacher, unhesitatingly displayed his wealth and power, once again deeply shocking Tsunade.

"How should I cooperate?"

With a change of expression, Tsunade asked with a smile.

"Can't you have some integrity?"

Jiraiya, lying on the adjacent hospital bed, couldn't help but complain, feeling that Tsunade was lowering the prestige of their three-person team.

"You're one to talk about integrity?"

Tsunade shot him a disdainful look, having long been annoyed by this pervert.

"None of you three have any integrity!"

Shimura Kentei grumbled inwardly. In Naruto, these three were the representatives of a lack of integrity, deeply mired in the path of gambling, women, and drugs, truly the shame of Konoha.

"Kentei-kun, if you need help with practicing the Body Strengthening Secret Technique, I think I can lend a hand."

At this moment, a handsome young man with long black hair walked into the ward. His golden snake-like eyes were filled with a burning passion, as if he had seen his beloved.

Who else could such a monstrous figure be but Orochimaru?

" (→_→) "

Are you sure you just want to lend a hand and not slice me up for research?

He grumbled inwardly, speechless, but Shimura Kentei didn't show it and happily said, "It would be even better if Senior Orochimaru could help."

"You two continuously channel Yang Release Chakra into me, flowing according to the guidance of my Chakra Threads."

After a simple instruction, Shimura Kentei quickened his breathing, and his throat produced rumbling sounds like muffled thunder, which was the core of the Body Strengthening Technique, Tiger Leopard Thunder Sound.

The complex sound waves reverberated within his body, tempering his entire body along with Chakra, including bones, tendons, muscles, skin, fascia, marrow, organs, meridians, acupoints, and even the neural network.

This tempering method greatly opened the eyes of Orochimaru and Tsunade; it was the first time they had seen such a miraculous training method.

Actually, Shimura Kentei's inspiration for creating this sound wave Body Strengthening Technique came from the martial arts novels he had read in his previous life, which mentioned the concepts of Tiger Leopard Thunder Sound and Hum Ha Two Sounds.

He wasn't sure if such magical martial arts truly existed in reality, but Shimura Kentei knew that three types of sound waves could produce resonance reactions with different objects. Infrasound could better resonate with soft matter, which was perfect for tempering muscles, skin, and internal organs.

Ultrasound could better resonate with solids, which was ideal for tempering bones. Combined with the human body's slight self-adaptation and evolution abilities, it resulted in the current Body Strengthening Secret Technique.

Of course, all of this was based on Chakra. Without the cooperation of Chakra, doing this would absolutely lead to death, and it had to be done slowly.

He had practiced the Body Strengthening Technique for several years before his physical fitness reached a level comparable to Rock Lee's during the Chunin Exams in the original work.

Don't underestimate Rock Lee, because in the Forest of Death during the second stage of the Chunin Exams, Rock Lee pulled a tree root with a diameter of over a meter with one hand from the ground to block an enemy's attack.

And at that time, Rock Lee had not used the Eight Inner Gates Formation, relying purely on physical strength. The strength of that was unimaginable, definitely in the tons.

Furthermore, the weights he discarded before fighting Gaara smashed two large pits in the ground, kicking up several meters of dust and causing the entire indoor arena to vibrate. The weight was definitely in the tons.

This means that he currently cannot defeat Rock Lee at the Chunin Exam stage, as the Eight Inner Gates Formation provides too much of a boost to Taijutsu, far beyond what his current Super Strength Technique and Super Speed Technique can match.

This training session lasted for a full hour before it stopped. Tsunade wiped the fine sweat from her forehead and said sternly, "Kid, you're being too reckless. This kind of training causes immense damage to your body, and the gains don't outweigh the losses."

"This method of strengthening the body does indeed come at a great cost!"

Orochimaru, on the other hand, agreed, his interest in the Shimura Clan's Body Strengthening Technique significantly diminished.

If it was a cultivation method that required such a huge price, its value would be greatly reduced. After all, there were plenty of similar methods, and compared to them, the Shimura Clan's Body Strengthening Technique was not particularly outstanding.

"What happened now?"

Jiraiya, who had been silent, saw his two friends with solemn expressions and asked worriedly, guessing that there might be a problem with the Body Strengthening Technique Shimura Kentei was using.
