Chen

He walked up to the top. He pointed to the left and right.

"The Eight Gates and Breath Activation Technique each have their advantages and disadvantages. Let me explain briefly - the Eight Gates has a higher difficulty. Even the first and second gates aren't something everyone can learn. It requires you to constantly challenge your physical limits," Kyōichi said, then paused to give everyone sufficient time to think.

The jōnin all looked towards Might Duy.

Recently, Might Duy had been promoted to tokubetsu jōnin. During this time, everyone had witnessed this "new jōnin's" peculiar behavior - doing extreme training every day while shouting embarrassing slogans, truly a performance art.

So.

When Kyōichi mentioned "challenging limits" and Might Duy's name was signed under the Eight Gates section, they immediately associated it with Duy's various bizarre behaviors, making them shudder.

Did one have to act like that to master the Eight Gates?

"Ahem, everyone please don't misunderstand. There are many ways to challenge your limits. Those are just my personal preferences, not the standard," Might Duy was familiar with these expressions. He stood up to explain.

"Duy-senpai, are there other methods?" Tekuno immediately asked.

"I personally kept increasing my training volume, persisted for a while, and eventually naturally opened the Gate of Opening, so..." Might Duy said awkwardly.

This was the truth.

This was how he taught Might Guy as well.

The jōnin fell silent.

Just training until it opens...

Simple and brutal.

However.

Learning it in a short time obviously couldn't use such a crude method. Their gazes shifted from Might Duy to Kyōichi. They had heard of Kyōichi's abilities.

Not to mention, Kyōichi's various educational ideas had become famous throughout Konoha recently. Anyone with children knew about these measures and their significance.

In Kyōichi's eyes right now, they were no different from the children he used to teach at the ninja academy.

"Of course there are other methods, but these methods are all unconventional. For example... rock climbing with one hand without using chakra," Kyōichi said.

This was how Kakashi did it.

Without using chakra, relying purely on physical strength to climb with one hand, challenging his limits, he eventually succeeded in opening the first gate.

As for the second Gate.

Once you had the first gate, this one became easier to open.

"One-handed rock climbing?"

Hearing the requirement, Tekuno could imagine how difficult it would be.

No wonder it could open the Gate of Opening.

Everyone fell silent again.

This was just the first gate.

The human body has eight gates - how monstrous must someone be to open all eight gates?

They heard...

This Might Duy was capable of opening all eight gates.

They looked at Might Duy, their eyes now filled with reverence and admiration.

There were many strong shinobi.

However.

Those who became this level of ninja purely through effort and struggle were extremely rare in the entire ninja world. Might Duy deserved their respect.

"So, shall we discuss the Breath Activation Technique now?"

"Yes, yes, yes!"

"Jōnin-Kyōichi, let's talk about the Breath Activation Technique. I think this one is easier, and it's more suitable for those of us who use ninjutsu."

"Indeed."

As soon as Kyōichi finished speaking, many jōnin immediately chimed in. Some even wondered...

If the Eight Gates was so difficult, what about the Breath Activation Technique?

Would it be simpler, or...

More difficult?

They had heard that Kanda Kyōichi occasionally had some educational quirks, perhaps this was one of those times.

However.

Soon, everyone dismissed their doubts.

Because after Kyōichi's explanation, they discovered that while the Breath Activation Technique was difficult, compared to the Eight Gates, this technique was much easier to get started with.

The challenge was how to master it in a balanced way, ensuring the whole body improved evenly, rather than having extremely active cells in one area while another part showed no improvement at all.

This required extremely strong chakra control ability, which was also the threshold condition that Kyōichi had been trying to lower.

However, after researching for a long time, even as the fourth activation was nearly complete, lowering the threshold still hadn't met requirements. Finally, he had to give up, and what the jōnin saw now was the final version.

"Using oxygen to enhance cellular activity indeed has a lower threshold than the Eight Gates," Tsunade spoke up. 

"However, correspondingly, the price is higher. The first two gates of the Eight Gates only cause minor damage to the body with little overall impact, while the Breath Activation Technique will reduce lifespan."

"Staying alive is what matters," someone said. "Reducing usage frequency means a bit of lifespan isn't much. Also..."

Speaking, he bowed deeply, full of pleading: "Duy-san, I want to ask you something. If my student can practice the Eight Gates, could you teach them the complete version?"

Kyōichi didn't recognize him at first because this person's appearance was vastly different from the anime, almost like a different person, but after hearing Duy's address to him, he immediately remembered.

"Chen-san, please don't do this. I'm not planning to hide the Eight Gates, it's just that this technique causes great harm to oneself, and the threshold is too high, which is why I only released the first two gates," Might Duy quickly helped him up while explaining.

Chen?

The taijutsu expert from the anime.

Kyōichi instantly remembered.

"My student only knows taijutsu, no ninjutsu or genjutsu at all. Others think he can't be a ninja, but he still became one."

"He made me believe that even with just taijutsu, one can become a qualified ninja. I want to give him a broader path!"

Chen began to talk about his student.

In terms of taijutsu skill, Chen was stronger than the current Might Duy and Might Guy, but once the Eight Gates opened, they weren't even in the same league.

In reality.

During the Third Shinobi World War, Chen's student died in battle due to not knowing ninjutsu or genjutsu, and Chen himself became depressed, faking his death and going into seclusion.

Kyōichi remained silent.

This was a taijutsu expert worthy of respect.

He looked toward Might Duy and Sandaime, not interfering, because Chen wasn't asking for the forbidden technique for himself, but for his student.

The nature was different.

"I can trade my taijutsu techniques!" Chen suddenly thought of his taijutsu.

This was all he had to trade.

"Could you demonstrate?" the Sandaime said.

He wasn't coveting the taijutsu, but rather couldn't set a precedent of freely giving away forbidden techniques, otherwise everyone would come asking for them citing various difficulties, and the concept of forbidden techniques would become meaningless.

"Chen-san, let me be your opponent. Meanwhile, I'll also demonstrate how to use the Breath Activation Technique and the Gates of Opening and Rest," Kyōichi stepped forward.

In terms of pure taijutsu, naturally Might Duy was stronger than him.

However.

When it came to coordination and highlighting an opponent's abilities, Might Duy definitely couldn't perform as well as him.

"Alright, I'll hold back..."

"No need, Chen-san. You can go all out, don't worry about hurting him."

Tsunade smiled.

Others also smiled knowingly.

Indeed.

Kyōichi himself was a medical expert, and with Tsunade, the world-renowned medical ninja present, anything short of death wouldn't be a problem.

Hearing this, Chen bowed gratefully, then formed the confrontation seal.

The next moment.

He launched his attack.

"Normal state."

Kyōichi didn't draw his sword, instead engaging in pure taijutsu.

When Chen was about to hit him, he avoided it at the absolute limit, but at this point, he had no chance to counterattack.

This wasn't an act - he truly had no opportunity—

Chen was too fast!

"So fast!"

Some jōnin exclaimed.

At Chen's speed, without using Body Flicker Technique or Substitution Jutsu, they couldn't dodge at all, yet Kyōichi avoided it with pure physical speed and reaction.

Just this point alone made everyone stop underestimating Kyōichi.

This kid's jōnin rank had zero padding!
