BXBX NOVEL Chapter 127: Kekkei Genkai and Secret Ninjutsu!
Chapter 127: Chapter 127: Kekkei Genkai and Secret Ninjutsu!
This was different from combination ninjutsu. Combination ninjutsu involves enhancing each element to boost the power of the jutsu, while a Kekkei Genkai is when two chakra natures combine to form a completely new nature—something far more complex and difficult to achieve.
Even with the Lava Release from the Four-Tails as a reference, Shūichi had been working tirelessly up until now.
Of course, this wasn't the only project he had been focusing on.
Time passed unnoticed. Nonō Yakushi and Asuka, who had gone out, returned home, but neither of them disturbed Shūichi.
As they crossed the courtyard, however, Asuka let out a surprised gasp, turning toward Shūichi.
"What's wrong?" Nonō Yakushi asked quickly.
Asuka, filled with excitement, exclaimed, "Shūichi has awakened a new power!"
Nonō immediately understood. "Lava Release?"
At that moment, molten lava chakra began to emanate from Shūichi's body, quickly enveloping him.
It was the Lava Release Chakra Mode, creating a Lava Armor around him!
"Finally, it's complete!" Shūichi lowered his hands and smiled.
This achievement had only been possible thanks to the Four-Tails' Lava Release as a model. Otherwise, the difficulty of creating a Kekkei Genkai would have been even greater—far more challenging than developing an S-rank forbidden jutsu.
"As expected, Kekkei Genkai is fundamentally different from ordinary chakra nature transformations."
"The Lava Release Chakra Mode... I don't even need to rely on the Yin Seal or the Creation Rebirth technique. While it helps that my chakra reserves have significantly increased, it's a fact that Kekkei Genkai powers are inherently easier to control."
Shūichi silently observed the changes.
He could feel his body being affected by the Lava Release chakra.
This sensation was different from when he had mastered Yang Release, Yin Release, or Lightning Release. There was something unique about this power.
"Perhaps it's because of the strength of the power, or maybe there's another secret to it."
"This energy is subtly soaking into my cells, imprinting itself into my very genes."
Shūichi pondered. "In fact, from a genetic perspective, there's no difference between Kekkei Genkai and ordinary chakra natures. I was born with Wind and Fire Release, inherited from my father and mother. Later, I gradually mastered several other nature transformations. In theory, my offspring could inherit these as well."
"They might inherit one, or several, or even all of them."
"And since Lava Release is a new nature transformation I've created, it too could be passed down to my descendants."
Whether it was regular nature transformations or Kekkei Genkai, they could potentially be inherited by future generations.
However, genetic information can sometimes be lost, and gene expression may vary.
"For example, the Uchiha clan's Sharingan requires a certain stimulus to activate. That's a specific form of gene expression."
"And there are some Uchiha who, despite experiencing such stimuli, never awaken their Sharingan—that's a case of genetic information being lost during inheritance."
Shūichi thought to himself that when the time came to have children, he would definitely have to prepare carefully. Only in his best condition could he ensure the highest likelihood of passing down his superior genes.
Reining in his thoughts, Shūichi dispersed the Lava Armor. Yet, inside his body, the Lava Release chakra continued to circulate, flowing through every cell via the Creation Rebirth technique.
This method was designed to accelerate the adaptation of his body to the new power of Lava Release, helping him to master it more thoroughly and efficiently.
The reason he had been able to manifest the Lava Release Chakra Mode and Lava Armor so quickly was that he had already become very familiar with Lava Release beforehand.
It was like a ninja who wasn't naturally attuned to Wind Release gradually mastering the nature transformation through training—they too would need time to become proficient and adept at its use.
...
"Shūichi, you're amazing!"
As Shūichi finished his training, Asuka and Nonō Yakushi quickly approached him.
Shūichi turned around, not even trying to be modest. "Of course!"
Nonō didn't say anything, only smiling warmly, but in her heart, she was truly happy. The stronger Shūichi became, the more secure their home would be.
At this moment, Asuka asked, "Shūichi, isn't it said that Kekkei Genkai can't be learned and can only be inherited through bloodline?"
Shūichi chuckled. "That statement isn't exactly wrong."
"Before I synthesized the nature transformation for Lava Release, I couldn't learn any Lava Release jutsu."
Asuka blinked in surprise. "Oh, so that's how it works?"
Shūichi smiled and asked, "Can humans learn to fly like birds?"
Asuka shook her head.
Shūichi continued, "But if you had wings like a bird, then you could learn to fly."
Asuka seemed deep in thought, while Nonō laughed softly. "It's similar to medical ninjutsu. Without first learning Yang Release nature transformation, you can't learn medical ninjutsu."
"Lava Release jutsu is the same. Without the Lava Release nature, it's impossible to learn it."
"Of course, it's usually said that Kekkei Genkai can't be acquired through learning because it's a new nature formed from the combination of two chakra natures. For one person to use two nature transformations in combination is already extremely difficult, let alone synthesizing a brand-new nature. Very few people can achieve that."
Shūichi nodded in agreement.
It's like the Uchiha clan's Sharingan, famous for copying abilities. Why can't it copy Kekkei Genkai or secret jutsu, the clan-specific techniques?
If you don't have the nature transformation of the Kekkei Genkai, how could you perform the jutsu? Kekkei Genkai techniques rarely require hand signs, making them even harder to replicate.
Then there are secret clan techniques, like the Inuzuka Clan's—leaving everything else aside, you'd at least need a ninja dog first, right?
And the Aburame Clan's secret insect techniques—without the insects, what would you copy?
In fact, even ordinary jutsu can't be copied by Sharingan without the right chakra nature. If you don't have the necessary chakra type, even if you know the hand signs and chakra flow, you still can't use it.
Otherwise, why is Kakashi the only one known as the Copy Ninja, despite so many Uchiha having three-tomoe Sharingan?
The reason is simple: Kakashi has mastered so many chakra natures that he can use the jutsu he copies immediately.
Also, intelligence plays a part.
Discussing whether something can be learned without considering the threshold or intelligence is unreasonable—and frankly, unfair.
The three of them entered the house, and Asuka joked, "Shūichi, does that mean you could learn my Adamantine Sealing Chains too?"
"After all, you're an expert in sealing techniques, and you've mastered Yin Release as well!"
Shūichi thought for a moment and cautiously replied, "If I understand the principles and have the right mindset, it shouldn't be impossible."
The Adamantine Sealing Chains were ranked A-rank in difficulty!
Of course, A-rank techniques are already very challenging, surpassing the difficulty level for most Jōnin.
But secret clan techniques, especially those involving unique bloodline traits, often had principles that even the users themselves couldn't fully explain.
Like Asuka herself.
Her Adamantine Sealing Chains had been awakened through a stimulus—something that just burst out from within her.
So, when the conversation turned to principles, Asuka felt a little embarrassed and quickly said, "I'll ask Kushina tomorrow—she should know the details!"
Nonō hesitated slightly and said, "Wouldn't that be a bit intrusive? After all, it's a clan secret technique."
Asuka shrugged it off. "The Land of Whirlpools and Uzushiogakure have been destroyed. Now it's just me and Kushina left from the Uzumaki Clan. There might be others scattered around, but it's not like we're still a united clan. There's no point in keeping it secret anymore."
Then she smiled again, adding, "Besides, Shūichi is family to me—and to Kushina too. She even taught you the Dead Demon Consuming Seal, which is a forbidden jutsu! She's like a mentor to you, so she wouldn't mind."
Hearing this, Nonō laughed and nodded. "Then let's give it a try!"
Shūichi, however, wasn't as optimistic as Asuka, but he was somewhat hopeful.
It wasn't that he absolutely had to learn the Adamantine Sealing Chains, but by studying the technique, he could expand his own knowledge of sealing jutsu and perhaps lay the foundation for creating his own unique sealing technique.
...
After chatting for a while, the three of them washed up, and before they knew it, it was already 10 PM.
Once they were in bed, Shūichi Hoshita's spiritual form manifested beneath the Tag Tree.
When he completed the Lava Release Kekkei Genkai, a new tag was triggered.
Shūichi looked up at the new tag leaf.
Tag: [Kekkei Expert]
Conditions to Obtain: Master at least 5 different Kekkei Genkai abilities.
Effect: Increases physical attributes by 100%, mental strength by 100%, body compatibility by 100%, and chakra nature transformation talent by 100%. Nature fusion now holds no secrets for you—the only thing holding you back is your body, your mind, and your wisdom.
Just from reading the effects, this tag was clearly on a different level than his previous ones.
This was at least on par with the [Ninjutsu Professor] tag.
But mastering five different Kekkei Genkai? Without the powerful [Transformation Master] tag, Shūichi would've found that idea daunting.
"One-Tail's Magnet Release, Four-Tails' Lava Release, Five-Tails' Boil Release... I'll need to further investigate the abilities of the other Tailed Beasts."
After dispelling his spiritual form, Shūichi quickly fell asleep.
---
The next day, before heading to the lab, Shūichi used the Flying Thunder God technique to make a quick trip to the Land of Wind, leaving behind a shadow clone before returning to Konoha.
The clone began to take the form of various birds in the Land of Wind, observing the progress of the war between the Sand and Stone ninjas. It also looked for opportunities to gather corpses for study.
If he could find a Kekkei Genkai user, that would be even better.
Additionally, the One-Tail of the Sand Village was also on Shūichi's radar.
---
When Shūichi returned home that evening, he found Asuka looking a bit down, so much so that she didn't even notice he had come back.
With a quick guess at what was bothering her, Shūichi sat beside her and gently asked, "Did Kushina-san also have trouble explaining the principle behind the Adamantine Sealing Chains?"
Asuka nodded, her spirits low. "Kushina said Lady Mito guided her in mastering the Adamantine Sealing Chains, but she couldn't explain it clearly either."
Shūichi placed his arm around Asuka's shoulders and smiled. "That's normal. Even before the fall of the Land of Whirlpools, not everyone could master that sealing technique."
"Besides, not every Uchiha can awaken the Sharingan, and they can't really explain its principles either."
"I couldn't tell you how to combine two nature transformations to get Lava Release—it's not a matter of formula or proportion."
"I could only understand the Lava Release through directly feeling the power of the Four-Tails and slowly attempting it until it clicked."
Some things are too mystical to be put into words.
Seeing that Shūichi wasn't disappointed, Asuka felt a bit better, though she still couldn't shake her feeling of frustration.
After coming to Konoha, Asuka had become much more outgoing, but due to her childhood in Kusagakure, she still had a gentle nature and cared deeply about the feelings of others—especially those close to her.
She had a strong need to feel useful.
After thinking for a while, Shūichi said, "Actually, there's another way!"
Asuka immediately perked up. "What is it?"
Shūichi smiled. "The mental world, of course!"
"Don't forget, chakra can link people's minds, and in the mental world, you can exchange information through chakra as well."
Uchiha Obito was able to lend his Sharingan to Kakashi after his death. In a world created by the chakra-linked mind, Asuka could potentially gain a more direct understanding of the Adamantine Sealing Chains, or even the Kagura Mind's Eye.
Though with the Listening Technique, there was no need to waste time on the Kagura Mind's Eye.
Remembering how Shūichi had helped her awaken the Kagura Mind's Eye and Adamantine Sealing Chains in the mental world before, Asuka's eyes lit up. She eagerly said, "Shūichi, let's try it now!"
Shūichi chuckled helplessly. "Let's eat dinner first."
Hearing this, Asuka quickly got up. "Then let's make dinner fast! Once Nonō comes back, we can eat!"
Shūichi laughed and followed her into the kitchen.
After dinner, around seven o'clock, Asuka was already impatiently dragging Shūichi into the study.
Nonō, seeing this, smiled before heading out to Konoha Hospital.
Much like her work at the orphanage, Nonō diligently sent most of her earnings back to support the orphanage, continuing to care for it in her own way.
---
In the study.
Shūichi and Asuka sat across from each other, holding hands. Their chakras linked, and soon their minds connected, creating a mental world.
"Shūichi, what should I do?"
Inside the mental world, Asuka asked.
Shūichi replied, "Let down all your defenses. I'll take care of the rest."
Asuka nodded firmly. "Got it!"
"Alright, follow my lead."
"Now, use the Adamantine Sealing Chains."
Following his guidance, Asuka nodded. Soon, the sound of chains clattering echoed, and golden chains began emerging from her back.
"Very good!"
Shūichi continued, "Now, my chakra will merge into yours. Don't resist..."
As he spoke, his chakra slowly infiltrated Asuka's, fusing with her power.
The chains began to dance, and a layer of blue flames appeared on them.
But this was only the beginning of the fusion between Shūichi's and Asuka's power.
Layer by layer, Shūichi's chakra penetrated deeper, peeling back the outer shell of the Adamantine Sealing Chains to explore their secrets. This could only be done because Asuka had lowered her defenses.
In this state, it was almost as if Shūichi was reading the information hidden within Asuka's chakra and brain, though it was limited to the knowledge of the Adamantine Sealing Chains.
This was quite similar to how Shūichi had studied Lava Release by tapping into the Four-Tails' chakra.
The difference was that Shūichi had full control over the Four-Tails' chakra, while Asuka's power was not entirely his. She had merely allowed him to feel and study it.
But now that they had reached this step, the next stage seemed entirely possible.
